Title: Concave mirror and condenser
Inventor: OKAMOTO KOUJI
IPC: H01L31/00
Filed: 1978-08-16
Abstract: PURPOSE: To apply even and high light intensity to solar batteries and reduce the quantity of light deviating from the batteries by making the focal length at each part of the concave mirror gradually shorter at the portions further from the center of the concave mirror.  
     CONSTITUTION: The distances between the points of intersection of the parallel rays 5 incident to each part of a concave mirror 6 on the optical axis 4 and the center of the condave mirror are made closer to the concave mirror at the portions further from the optical axis 4. Then, the concentration of light at one point on the optical axis may be avoided, the light diffused even to the outer side from the optical axis and the light condensed at nearly even ligyt intensity on a colar battery cell 1. The provision of the solar battery cell 1 in the place further closer to the concave mirror from the closest focal length out of the respective focal lengths of the mirror improves effect further.

Title: Appearance inspection and equipment thereof
Inventor: SATOU TETSUROU
IPC: G03F1/84
Filed: 1984-05-21
Abstract: PURPOSE:To reduce the total time of an appearance inspection operation by detecting a defective position including an erroneous detection as the first inspection and further by excluding the erroneous detection from the defective position as the second and the later inspections. CONSTITUTION:At the first time, a stage 11 is moved at high speed, a threshold voltage is set at low value and an overall high detection rate inspection is carried out. In the second inspection, the stage 11 is driven at low speed at a defective position. The results are that many erroneous detections are excluded. In the third inspection, the stage 11 is stopped or driven at low speed and the threshold voltage is continuously varied from high to low value whereby almost all the erroneous detections are excluded. At last, a final judgement is done by human viewing and the erroneous detection, if any, is excluded. In this way, the time of an appearance inspection operation can be reduced.

Title: Method for multiplexing image signal, transmission method and system
Inventor: SUGIMORI YOSHIO
IPC: H04N7/01
Filed: 1999-04-07
Abstract: PROBLEM TO BE SOLVED: To generate an image signal suitable for up-convert to the HDTV system by frequency-converting a horizontal high definition area component or a vertical high definition area component in existence on and over a line specified by a signal standard of a specific system and superimposing the frequency-converted component onto a definition area whose signal component has been eliminated to make full use of components having conventionally been cut by a filter of a camera or the like according to the standards. SOLUTION: In the case of up-converting an image signal of the 480 P system to an image signal of the HDTV system, a component in an area A (horizontal high definition area-vertical high definition area) is cut off among components of 480 P system image signals on and above a slanted line 1 tying a point 1080 Lpw and a point 480 Lph, a component of an area B (horizontal high definition area-vertical low definition area) is frequency-converted and superimposed onto the area A. The range of the area A to be cut off ranges from a vertical high definition is 320 Lph or over with respect to a horizontal high resolution of 1080 to a horizontal high definition of 360 Lpw or over. A decoded image signal has higher horizontal definition than that of the image signal of the 480 P system and then a picture with an excellent high resolution characteristic can be obtained.
