Abstract: PURPOSE:To prevent the occurrence of frame-form unexposed portions at the end parts and both side parts of photosensitive paper through simple operation of thurning a knob by the simple constitution of providing end exposure lamps and shield plates as well as side exposure lamps and shield plates. CONSTITUTION:When at the time of setting the magnification of the copying apparatus a shield plate 23 is set at an optimum angle by turning a dial knob 29 if necessary, then the side exposure lamps 31 and shield plates 41 are moved to suitable positions by the movement of a wire 36. When photosenstive paper 19 is fed by operation of a print button, the side exposure lamps 31 go on to expose both side parts of the photosensitive paper 19. Upon stopping of the photosensitive paper 19 in the exposure position, the side exposure lamps 31 are put out and the image exposure by the exposure light souce 10 and the exposure by the exposure lamps 22 are accomplished.

Title: Camera system
Inventor: EGAWA TAKESHI
IPC: G03B7/0805
Filed: 1989-03-20
Abstract: PURPOSE:To eliminate unnecessary operation at the time of selective operating and to make operation when photographing more efficient by permitting a 2nd selecting means to select a desired exposure mode after a 1st selecting means selects the combination of plural exposure modes. CONSTITUTION:Generally, a program mode P, a diaphragm prioritizing mode A, a shutter prioritizing mode S, a manual mode M, etc., are prepared as the exposure mode. The camera system includes the 1st selecting means selecting the combination of plural exposure modes, and the 2nd selecting means selecting one exposure mode from the selected combinations. When the mode M is not required, for instance, the 1st selecting means can group the exposure modes P, A and S. Therefore, when a photographer would like to switch the currently selected mode A to the mode P, selective operation by the 2nd selecting means requires only twice operations; A S P. Consequently, when a photographer selects the exposure mode being used, unnecessary operation is eliminated.

Abstract: PURPOSE:To obtain a second insulating film whose characteristic is stable by a method wherein a first insulating film damaged by an ion implantation operation is removed and the second insulating film is formed newly. CONSTITUTION:Ions of impurities whose conductivity type is identical to that of an n-type layer 14 are implanted; an N-layer 17 is formed. At this time, an oxide film 15 is damaged. After that, the oxide film 15 in a tunnel window is etched in a state that a resist 16 is applied. At this time, the end of a field oxide film 12 is etched simultaneously; a field region is retreated.

Abstract: PURPOSE:To reduce the difference of optical outputs between the center part and the peripheral part and improve image contrast by using the phase plate on which thin membrane is formed by evaporation so that light transmissivity increases gradually from the center part to the peripheral part. CONSTITUTION:As for the phase plate of a glass panel which has evaporated thin membrane on the inner surface, the light transmissivity at the center part is set for example at 60%, and it increases gradually toward the peripheral part, and is set for example at 85% at the peripheral part. The opening rate of the black light absorbing layer and the luminescent layer which have openings are set so as to be smaller from the center part of the phase plate to the peripheral part. Accordingly, the light transmissivity at the center part becomes pretty smaller, and image contrast can be improved sharply, and a colour image receiving tube having high quality can be obtained.

Abstract: PURPOSE:To obtain linearly polarized laser light the uniform and stable laser cutting property by changing this linearly polarized laser light to circularly polarized laser light using a phase retarder, by a method wherein linear grooves are provided at least one of either reflection surfaces of a total reflecting mirror or a partly transmitting mirror. CONSTITUTION:The total reflecting mirror 6 has plural numbers of V shaped grooves 7 with 90 deg. angle to the reflecting surface, and linearly polarized laser light 8 is generated from the V shaped groove 7. In the laser cutting, it is asked to output stable circularly polarized laser light to obtain work pieces having uniform cutting property. Hereby, the laser oscillator generates linearly polarized light. For this purpose, it is necessary to provide an adequate polarizing element in the laser oscillating cavity. Since the groove 7 which is provided at the reflecting surface of the total reflecting mirror 6 has a characteristic of the least attenuation of laser light having polarized light in the groove direction, laser light 9 which comes in the total reflecting mirror 6 is reflected to the same direction and the loss of laser oscillation becomes low, the groove 7 being made V shape. Furthermore, linearly polarized laser light 8 can be generated, polarized light being given when laser light is reflected.
