Title: Controller for opening and closing back cover of camera
Inventor: WAKABAYASHI HIROSHI
IPC: G03B17/02
Filed: 1989-12-21
Abstract: PURPOSE:To prevent a back cover from being opened as long as neither 1st nor 2nd switching means is in an on-state by manually operating the 2nd switching means and transiting a back cover opening inhibition means to a released state when the 1st switching means is in the on-state. CONSTITUTION:The controller is provided with a detection means 15 for detecting that the frame of a film where photographing is executed or not executed is housed in a cartridge, the 1st switching means 13 which becomes in an on-state at the time of detecting that the frame of the film where photographing is executed or not executed is housed in the cartridge, and the 2nd switching means 1 which becomes in an on-state when it is manually operated. When both the 1st and the 2nd switches 13 and 1 are in the on-state, the back cover opening inhibition means 2 is energized to be transited from an opening inhibiting state to an opening inhibiting released state. By providing the 2nd switch 1 at a position where it is easily used, operability is improved and the frame of the film where photographing is executed or not executed is prevented from being exposed by malfunction.

Title: Ferroelectric liquid crystal element
Inventor: KAWAGISHI HIDEYUKI
IPC: G02F1/1337
Filed: 1987-12-28
Abstract: PURPOSE:To improve the contrast of a ferroelectric liquid crystal for which an org. oriented film is used when said cell is used as an optical shutter by using the oriented layer formed by projecting an ion beam from a diagonal direction on the org. oriented film subjected to a rubbing treatment, thereby increasing the apparent tilt angle thereof. CONSTITUTION:Transparent electrode 3 are patterned and formed on a glass substrate 2 which supports the liquid crystal, then an SiO2 film is formed by a sputtering method on the transparent electrodes 3. After polyimide is spin- coated on the SiO2 film, the coating is calcined to form the org. oriented film and the org. oriented film is subjected thereupon to the uniaxial orientation treatment by rubbing using an acetate cloth; thereafter, the ion beam is projected on the org. oriented film from the diagonal direction to form the oriented layer 4. The apparent tilt angle of the cell is increased if the cell is produced by disposing two sheets of the resultant substrates 2 to face each other in such a manner that the rubbing directions with the upper and lower substrates are reversed from each other. The contrast when the cell is used as the optical shutter is thereby improved.

Filed: 1991-11-18
Abstract: PURPOSE:To manufacture a source corresponding to wide vision in an excellent way with high resolution by compensating a deficiency in the horizontal direction by means of optical compression method so as to implement image pickup with a required aspect ratio. CONSTITUTION:A CCD image sensor corresponding to the PAL system is used and since the size in the horizontal direction is 9.048mm, the aspect ratio of a hatched area WP is 9.048:5,577=14.6:9 and the aspect ratio of 16:9 cannot be obtained. Then as to the deficiency in the horizontal direction, an anamorphic lens 10 is used to compress a picture, resulting in obtaining the aspect ratio of 16:9. That is, when the vertical direction is 5.557mm, since the size in the horizontal direction to obtain the aspect ratio of 16:9 is 9.915mm, the picture is compressed by the anamorphic lens 10 so that the size 9.915mm corresponds to the size 9.048mm. In this case, the compression rate is 0.91 and the compression of nearly 0.9% is obtained.
