A semiconductor device includes a terminal electrode (4) and a terminal electrode placement member (21). The terminal electrode includes a substrate-fixed portion (31) secured to the circuit substrate (11) through a fastening member (36), and an external wiring connection portion (30) to which an external wiring is connected. The terminal electrode placement member includes a plurality of securing portions (122) which are secured to the circuit substrate, and a rotation suppressing portion (21) configured to suppress rotations of the terminal electrode. The rotation suppressing portion is provided with a penetration hole (121b) for penetrating the substrate-fixed portion therethrough. The rotation suppressing portion includes a pair of walls (121a) which are opposed to each other and also are positioned in opposite sides beside the terminal electrode which is inserted into the penetration hole at the substrate-fixed portion. The terminal electrode comes into contact with these walls, thereby suppressing the rotation of the terminal electrode.

A drafting device includes a pressing portion that increases the contact pressure between a back bottom apron and a back top apron without changing the contact pressure between a middle bottom apron and a middle top apron. This does not hinder feeding of fibers of a first roving that are held by a front bottom roller and a front top roller. Additionally, separation of fibers from a second roving and breaking of the second roving may be limited between the holding position of the front bottom roller and the front top roller and the holding position of the back bottom roller and the back top roller.

A fiber bundle supply interruption device for a spinning machine includes a drafting unit (10), which includes a back roller (14a, 14b), a duct (31), which has a length that is greater than or equal to a length of four spindles, and a fiber bundle holding mechanism (34), which is coupled to the duct. The fiber bundle holding mechanism holds a fiber bundle to be supplied to the drafting unit at a position rearward from the back roller of the drafting unit. The fiber bundle holding mechanism includes a holding member (34), which holds the fiber bundle, a biasing member (38), which biases the holding member from a fiber bundle releasing position to a fiber bundle holding position, and an actuator (40), which switches the holding member between a state in which the holding member is maintained at the fiber bundle releasing position and a state in which the holding member is released from the maintained state. The duct accommodates wiring (43, 44) required for driving the actuator.

A connecting terminal (6,7,8) includes an external terminal connecting portion (30), having an end surface to connect an external terminal thereto and located at a second principal surface side (13a) of a second circuit board (13), and a substrate-fixed portion (31) which is securely connected to a first circuit board (11). A seal attachment portion (35) is provided on a portion of the external terminal connecting portion including the end surface to attach thereto a seal member (34) to seal a gap between the portion and the case (14). The connecting terminal includes a reduced sectional area portion having a sectional area smaller than an area of the top end surface in a region close to a plurality of electronic components (9) arranged on the second circuit board (13) on the external terminal connecting portion. The reduced sectional area portion is provided from the seal attachment portion to an end in the opposite side of the end surface.

In a method for controlling a drafting device of a spinning frame, the drafting device includes a front bottom roller 12, a middle bottom roller 13, a back bottom roller 14, and motors (15, 16a, 16b, 17a, 17b) that independently drive the bottom rollers. The method includes changing a break draft ratio of the drafting device in a deactivation process of the spinning frame so that a load torque of the drafting device is smaller than when the break draft ratio is set to a value for normal operation to limit untwisting of the bottom rollers. The method further includes changing a main draft ratio when a fiber bundle, which has passed by the middle bottom roller 13 during a period the break draft ratio is changed, passes by the front bottom roller 12, to cancel influence on the fiber bundle of the changing in the break draft ratio.

An apparatus and a method for controlling steering of an industrial vehicle includes a wheel angle detector, a travel determining device, and a control calculation device that calculates a wheel angle average and a maximum variation of wheel angle in the specified period and learns a reference steering limit angle. The control calculation device determines that the steerable wheel is in a steering limit state if an actual traveling speed is maintained at the specified speed or higher for the specified period of time or longer, the average wheel angle in the specified period of time is at a specified angle or greater, and the maximum variation of wheel angle in the specified period of time is at a specified value or less. The control calculation device renews the reference steering limit angle if the steerable wheel is determined to be in the steering limit state.
