Abstract: Disclosed herein is an automatic locking retractor suitable for use in vehicle seat belt. The retractor is constructed of a take-up spindle, a cog wheel mounted integrally with the spindle, a latch gear integrally rotatable with the cog wheel, a lock lever normally kept in engagement with the cog wheel, a control member and sensor means. The control member is normally biased to a position where it is engageable with the latch gear. The control member can assume a first and second working positions when the take-up spindle is rotated respectively in the pulling-out and winding directions of the webbing. In the first and second working positions, the control member is in contact with the path of rotation of circumference of the latch gear. The control member holds the lock lever in a position where the lock lever permits free rotation of the cog wheel when the webbing has been pulled out and the control member has moved toward the first working position.

Abstract: A spin drier including a casing and a rotor equipped with at least one holder for a carrier, which is adapted to enclose a semiconductor material such as a silicon wafer therein, and embraced in the casing so that the semiconductor material placed on the rotor is dried by a gas stream which has been introduced through an intake port provided above the rotor, passes through the rotor and is to be exhausted through an exhaust port formed through a circumferential wall of the casing. The rotor is provided with at least three guide members on the outer section thereof, and each guide member includes a substantially vertically disposed curved surface with its convex side faced inwardly. The described holder is positioned between two guide members, to thereby guide the above described gas flow and thus prevent water, dusts and/or stains located on the bottom wall and circumferential wall of the casing from flowing back onto the semiconductor materials.

Abstract: A clutch brake arrangement for farm work machinery or other equipment comprises a rotary member rotatably attached to an output shaft extending through a cam plate mounted on an engine mounting. A pressure plate is mounted on the cam plate in such a manner that it is movable along said output shaft. A brake spring is provided to bias the pressure plate toward the rotary member. A lining plate is disposed between the rotary member and a clutch disc rotatable with the output shaft. A clutch spring is provided to bias the lining plate toward the clutch disc to engage it with the pressure plate. The pressure plate is moved toward the cam plate against the brake spring, so that the lining plate is engaged with the clutch disc and, thereafter, is spaced away from the pressure plate. A plurality of projections are discontinuously formed on the peripheral portion of the pressure plate which is outside of its braking plane.

Abstract: In a training unit for aiming at fictitious targets as applicable in particular to a firing simulator, provision is made for an optical sighting device in which the line of sight from reticle image to target is orientable at least at the start of a fictitious-firing event. Target signals define successive images of a fictitious target as a function of the shape and continuous relative displacement of the target at least in distance from the training unit and/or in angular position with respect to the line of sight. Each successive target image is formed by means of a luminous point moving on a screen, the successive images thus formed being projected in the field of view of the sighting device.

Abstract: After subjecting a semiconductor element to etching, it must be washed with water and then dried so as to remove any etchant therefrom. In the course of the washing and drying steps, the semiconductor element may undergo quality changes due to its contact with water. Such quality changes become remarkable when the semiconductor element is kept for a long time period in the resultant washings. The above quality changes can be successfully avoided by holding an etched semiconductor element horizontally over a water-washing tank, pre-washing its downwardly-directed front surface with an upward jet of water, thoroughly washing the front surface with pure water blown upwardly from a lower part of the tank while washing its upwardly-directed rear surface with water so that both surfaces of the semiconductor element are washed completely, and then immediately spin-drying the thus-washed semiconductor element.
