An ink jet recording method includes: a reaction liquid attaching step of attaching a reaction liquid containing an aggregating agent and water to fabric by an ink jet method; a transparent ink attaching step of attaching a transparent ink composition containing water and anionic resin particles aggregated by the aggregating agent to the fabric by an ink jet method; and a metal foil attaching step of attaching metal foil to a region to which the transparent ink composition is attached, in which the difference in landing time on the same area of the fabric between the reaction liquid attaching step and the transparent ink attaching step falls within 60 seconds.

A light source apparatus includes: a light guide having a side surface extending in a first direction, a first end surface oriented in the first direction, and a second end surface oriented in a direction opposite the first direction; an angle converter bonded to the first end surface and configured to convert an angle of light output via the first end surface; a light emitter configured to emit light toward the side surface, a holding member with which the angle converter is in contact in the first direction; and a base at which the light guide and the holding member are disposed, the angle converter including a light passage portion, and a flange protruding from the light passage portion in a direction intersecting with the first direction, the base having a first facing portion, the holding member having contacts with which the flange is in contact along the first direction, and a second facing portion facing the first facing portion in the first direction, and the holding member being fixed to the base with an adhesive that fills a clearance provided between the first facing portion and the second facing portion.

The ink jet ink composition according to an embodiment of the present disclosure contains water, a reactive dye, and a water-soluble compound with a melting point of 50°C or higher, and the content of the water-soluble compound with a melting point of 50°C or higher is 10% by mass or more and 40% by mass or less with respect to the total amount of the ink composition.

A flow path cleaning method for a preventive dental device is provided. The device includes a mixer having a powder storage portion storing a tooth surface cleaning powder, a handpiece having a nozzle portion, and a control unit. The mixer feeds compressed air to the powder storage portion to generate powder mixed gas and supplies the powder mixed gas to the nozzle portion through an internal air feeding path and an external air feeding path. The method includes an automatic cleaning process for cleaning the internal air feeding path and the external air feeding path. When an execution request of the automatic cleaning process is input to the control unit, compressed air is fed to the powder storage portion after stored powder has been removed, and the compressed air is discharged from the nozzle portion after flowing through the internal air feeding path and the external air feeding path.

A projector includes: a first light source that emits first light; a second light source that emits second light in a direction intersecting a direction of emission of the first light from the first light source; a first image generation element that generates first image light from the first light; a second image generation element that generates second image light from the second light; a first heat dissipation member that is thermally coupled to the first light source and dissipates heat generated in the first light source; a heat transport member that transports heat generated in the second light source; a second heat dissipation member that dissipates the heat transported by the heat transport member; and a first cooling unit that circulates a first airflow through the first heat dissipation member and the second heat dissipation member along a first direction, and at least a part of the first heat dissipation member and at least a part of the second heat dissipation member overlap each other in the first direction, the second light source includes a light-emitting element that emits the second light, and a substrate that supports the light-emitting element, and the heat transport member extends in a straight line along the substrate.

A method for washing a preventive dental device is provided. The preventive dental device includes a plurality of dental handpieces each having a water injection port and a body portion to which the dental handpieces are connected. The body portion has an internal liquid feeding path connected to a water supply source and supplies the water the dental handpieces. The method washes a plurality of branched liquid feeding paths branched from the internal liquid feeding path toward the respective water injection ports by feeding a liquid such as water or a chemical solution. The method includes supplying the liquid from the water supply source to the internal liquid feeding path; and intermittently supplying the liquid to the branched liquid feeding paths from branch points between the internal liquid feeding path and the branched liquid feeding paths to the respective water injection ports.

A projector includes: a first light source; an optical system configured to emit image light based on light from the first light source; a housing having a first surface and configured to house the first light source and at least a part of the optical system; a plurality of second light sources different from the first light source and configured to emit light from the first surface side to an outside of the housing; and a controller provided to the housing and configured to control the plurality of second light sources.

A technique of monitoring the condition of a vehicle occupant is presented. The technique monitors a combination of characteristics of eyes an occupant of the vehicle, and associated illumination conditions, to determine the occupant's condition, and cause a vehicle function to be performed in dependence upon the determined condition.

A method for manufacturing an inorganic alignment film includes a first step of forming pixel electrodes at a substrate; a second step of forming a first film by vapor deposition so as to cover the substrate and the pixel electrodes, the first film having multiple first columns each having a major axis direction being a direction along a Z-axis; a third step of forming a second film on the multiple first columns by vapor deposition, the second film having multiple second columns each having a major axis direction that intersects at a first angle with the direction along the Z-axis; a fourth step of forming a protective film on the multiple second columns by atomic deposition; and a fifth step of forming a third film on the protective film by vapor deposition, the third film having multiple third columns each having a major axis direction inclining by a second angle smaller than the first angle with respect to the direction along the Z-axis, the third film being thinner than the second film.

A thermal printer (100) includes a thermal head (31), a platen roller (32), a fixed blade (41), a movable blade (42), and a non-adhesive member (44a) arranged on the adhesive surface side of a recording medium. The blade edge moves beyond the non-adhesive member when cutting and retracting, enabling the non-adhesive member (44a) to peel the medium from the blade without a separate peeling mechanism.
