Title: Photovoltaic element
Inventor: KARIYA TOSHIMITSU
IPC: H01L31/04
Filed: 1993-05-07
Abstract: PURPOSE:To suppress the recoupling of light-excited carriers near the interfaces between a ZnO and pin layers and between the ZnO layer and a substrate by varying the phosphor content of a zinc oxide thin film layer having specific surface ruggedness and c-axis orientation so that the content can become the minimum at the interface with the substrate and gradually increase towards the pin layer. CONSTITUTION:This element has a zinc oxide thin film layer 102 and pin layer (p-, i-, and n-layers) composed of a non-single crystal silicon semiconductor material which are successively formed on a substrate 101. The layer 102 is composed of a crystalline layer having c-axis orientation, has surface ruggedness of 0.1-1.0mum, and contains phosphor. The phosphor content of the layer 102 varies in the thickness direction, with the content being the minimum at the interface with the substrate 101 and gradually increasing towards the layer 103. Therefore, not only the open-circuit voltage, short-circuit current, and photoconversion efficiency of the element can be improved, but also the optical deterioration and vibrational deterioration of the element can be suppressed under a high-humid condition.

Title: Projection lens
Inventor: KASHIWARA TAKASHI
IPC: G02B3/00
Filed: 1986-05-09
Abstract: PURPOSE:To obtain a projected image having an excellent resolution and a high visibility by placing an optical filter for making a light beam of a specific wavelength area pass through partially, in the front part, the rear part, or between lenses, of a lens system constituted of plural lens elements. CONSTITUTION:An optical filter 3 is installed in front of the first lens L1, and a focusing adjustment is executed by rotating and sliding an inner lens barrel 2 and adjusting an air interval between the second lens L2 and the third lens L3. The part to which hatching is performed, of the optical filter 3 shows a filter part 3a which is colored or on which a thin film has been formed, for selecting and filtering alight beam. Although it is allowed to attach the filter to the whole surface, if it is executed, the passing quantity of a light beam decreases, and lightness of an image surface falls, therefore, it is undersirable. In general, as for a light beam for passing through the outside peripheral area of the lens, its aberration becomes large, therefore, it is effective for reducing a color bleeding of an image to cut off an unnecessary light beam for passing through the outside peripheral area, and a fall of lightness of the image surface can be made as small as possible.

Title: Support structure of steering column
Inventor: TANAKA TOSHINORI
IPC: F16F7/00
Filed: 1999-04-15
Abstract: PROBLEM TO BE SOLVED: To reduce noises of a motor-driven power steering device, and to reduce the transmission of vibration to a car body from the steering column side by forming a structure of installing a car body installing bracket on the car body via an elastic body. SOLUTION: A bolt 8 is fastened between a car body installing bracket 4 and a car body 7 by a nut 9 via an elastic body 10 by insert molding. Thus, since a steering column is supported via the car body 7 and the eleastic body 10, the transmission of vibration can be reduced, and since support is the elastic body 10, installing dimensional accuracy of the car body installing bracket 4 can be relieved. At vehicle colliding time, the support elastic body 10 deflects in the shearing direction to relieve impact applied to a driver when the driver collides with a steering wheel 1. Since rigidity of a support part can be varied, a natural frequency can be adjusted, and for example, resonance in an unpleasant frequency can be avoided.
