Abstract: There is provided a spread illuminating apparatus to make effective utilization of light emitted from a light source. A light reflection plate is provided along and close to a side surface of a light conductive member opposite to a side surface facing a transparent substrate, and has on a surface thereof a plurality of prismatic projections facing toward the light conductive member and arrayed along the longitudinal direction thereof. A reflection layer is formed on the projections. Light having penetrated inclined walls at the light conductive member is reflected by means of the reflection layer along the optical axis to be effectively utilized.

Abstract: A leg rest and a seat back are rotatably mounted at the front and the back of a sea cushion of a motor-driven seat, respectively. A foot rest is mounted on the leg rest so that it can be extended and retreated. Motor-driven actuators each having a potentiometer are individually connected to them. The motor-driven actuators are controlled by a controller in response to an input of an operation switch, based on a position determined by the potentiometer, and in accordance with a predetermined reference position, thereby adjusting the angles and the positions of the seat parts. The motor-driven actuator is temporarily moved to the end of the stroke, so that limit switches are activated, and the reference position is adjusted based on the position determined by the potentiometer, thereby significantly reducing the amount of adjustment work.

Abstract: During the assembly of a small motor, insulation is installed on the outer surface of a magnetic pole. An armature coil is wound so that the wire does not touch the corners of the magnetic pole. The wound coil does not loosen and sufficient insulation for the armature coil and magnetic pole gap can be secured when the assembly is completed. This allows as much ampere turn of the armature coil as possible to be obtained. Moreover, the thickness of the motor can be made flatter resulting in easier assembly of the flat motor's stator.
