Title: Film pressure plate for camera
Inventor: NIKAIDOU HIDEO
IPC: G03B17/28
Filed: 1982-03-27
Abstract: PURPOSE:To prevent a camera from electric discharge by coating the surface of a film pressure plate which is in contact with a film formed from a material of which main component is Al2O3 by a vapor deposition method n, sputtering method, ion-plating method, or chemical vapor deposition method.

Filed: 1999-02-26
Abstract: PROBLEM TO BE SOLVED: To make a range-finding device executing a hybrid type range-finding action that an active range-finding action and a passive range-finding action are executed so as to be hard to be affected by noise without increasing the number of comparators used for deciding the finish of the accumulation of a signal. SOLUTION: The external light quantity decision comparators 17L and 17R used for judging whether a skimming action used at the time of the active range-finding action is executed or not are used for judging whether signal amount required for the range-finding arithmetic operation at the time of the passive range-finding action is accumulated or not. At this time, the skimming actions by skimming action parts 16L and 16R are not executed. Then, when it is judged by the comprators 17L and 17R that the signal amount required for the range-finding arithmetic operation at the time of the passive range- finding action is accumulated, an inverted signal is inputted to a CPU 21 from the comprators 17L and 17R. By the CPU 21, a control signal for finishing the accumulation of the signal is outputted to photodetectors 15L and 15R through a control circuit 22.

Title: Optical printer
Inventor: MOROZUMI SHINJI
IPC: G02F1/11
Filed: 1985-03-14
Abstract: PURPOSE:To improve the optical response speed of a photosensitive body by using a light-light transducer using a liquid crystal light valve. CONSTITUTION:When light is not made incident on a photoelectric converting film 25 of a liquid crystal light valve 33, a voltage is not applied to a liquid crystal because the resistance of the liquid crystal 23 is lower than that of the photoelectric converting film 25. When light is made incident on the photoelectric converting film 25, the resistance of the photoelectric converting film is reduced to apply a voltage to the liquid crystal. As the result, the reflected light from a dielectric film 24 of the incident light from a light source 30 can be controlled because the contrast of light and darkness is made between application of the voltage to the liquid crystal and non-application on of the voltage to the liquid crystal. Consequently, the light from the light source 30 forms a primary image, which is formed on the light valve 33 by a laser beam 32, as a secondary image on a photosensitive body 27.

Abstract: PURPOSE:To obtain a stable flaw detection means by a method inwhich corner section of a test material and the area around there is heated nearly up to the Cury point of the material and the corner section is magnetically saturated. CONSTITUTION:An exciting coil 3 is wound on a core 4, on which a test sample is put and is magnetized with D.C. source. There is, then, arranged a probe coil 2 for flaw detection around the intermediate point between the both magnetic poles of the core 4. By means of using such a device, it is conducted comparison between two cases: one is the sample being magnetized and the other is the same is being nonmagnetized. In the case of being magnetized, the phase angle induced from flaw signal varies nearly only within 5 deg.-10 deg. for the temperature variation range of 500- 900 deg.C and the variation of output level of flaw signal remains only within 5%. Against such a degree, however, in the other case of nonmagnetized, the both of phase angle and output vary in large scale nonlinearly at discontinuous boundary point being nearly close to 750 deg.C. There is found also the variation of phase angle of about 60 deg. for the temperature difference between less than or equal to 750 deg.C and more than or equal to 800 deg.C and still further the output level for about 750 deg.C or more than that is remarkably unstable.
