Abstract: The disclosure relates to a light controlling sheet for use with indicators which includes a louver element including an arbitrary pattern of walls which are parallel to each other and opaque so as to absorb light, and an electrically conductive film which is mounted on one surface of the louver element. This film is porous so that the light from a light source may penetrate. The oblique light strikes the opaque walls of the louver element and is absorbed in the walls, while the substantially parallel light is permitted to pass through the space or transparent portion betwee the walls. The electrically conductive film not only acts as a protective cover for the louver element but also shields unwanted electromagnetic wave.

Abstract: An apparatus for providing stepwise movement along an elongated stepped member. A holder contains at least one button that includes a pivotally mounted claw disposed to engage the stepped member when the button is depressed. The claw pivots upon engagement with the stepped member and further depression of the button moves the button and holder laterally a distance determined by the steps on the stepped member.

Abstract: There is disclosed an operating circuit for an electric discharge lamp in which a first DC operating circuit for starting an electric discharge lamp, a second DC operating circuit for making the electric discharge lamp operative by a voltage near a rated lamp voltage and by a current near a rated lamp current, and a third DC operating circuit for supplying a relatively large current to the electric discharge lamp immediately after the electric discharge lamp is started and for stabilizing the lamp luminous flux in a short time, are connected in parallel. A switching circuit for cutting off the first DC operating circuit after the electric discharge lamp is started is provided at the output terminal of the first DC operating circuit. In addition, reverse current preventing circuits for preventing the currents from reversely flowing from the operating circuits at higher voltages are provided at the output terminals of the second and third DC operating circuits.

A cylindrical ratchet wheel is coaxially rotatably supported on a shaft of a winding reel, and is covered with a case attached to one of the side plates of a frame of the device. There are provided a first spiral spring disposed in a doughnut-shaped space defined between the case and the ratchet wheel, and a second spiral spring disposed in the ratchet wheel. The first spring has one end fixed to the case and the other end fixed to the ratchet wheel, while the second spring has one end fixed to the ratchet wheel and the other end fixed to the shaft of the reel. The ratchet wheel is formed with a plurality of ratchet teeth on its periphery, and a ratchet is pivotally disposed in the case for releasable engagement with the ratchet wheel teeth.

Abstract: A turn indicator system for use in an automobile includes two sets of switches disposed around a steering wheel shaft for detecting, respectively, opposite directions of rotation of the steering wheel. The cancellation of an actuated turn indicator is carried out when the steering wheel, which has been rotated in one direction from its neutral position, is returned towards the neutral position.

Abstract: A seat belt winding apparatus for a vehicle comprises a winding reel and spring means having one end connected to the winding reel and the other end connected to a stationary part of the apparatus. The spring means is constituted by two spiral springs connected to each other though an interposed ratchet gear rotatably mounted on a stationary part of the apparatus. There is provided for controlling rotation of the ratchet gear controlling means which includes a pawl adapted to releasably engage with the ratchet gear, electro-magnetic means for selectively actuating the pawl and a switch which responds to the states of the vehicle to selectively energize the electro-magnetic actuator means, thereby to control the combined force of the first and second springs in dependence on whether the pawl is engaged with the ratchet gear or not and hence in dependence upon the prevailing states of the vehicle.

Abstract: A seat belt system for vehicle wherein one end of a seat belt for restraining an occupant is firmly engaged with one end of a steel strip which is held and guided by an anchor member firmly attached to a vehicle body in such a way that when the impact energy acts upon the seat belt, thereby forcing the steel strip out of the anchor member, the strip may be subjected to plastic deformation at least at two positions, whereby the impact energy may be converted into the forces for bending the steel strip as the latter being pulled out of the anchor member. Thus, the impact energy acting on the occupant during a collision may be effectively and safely absorbed.
