IPC: G03B7/091
Filed: 1980-10-17
Abstract: PURPOSE: To enable input operation of high precision by simplifying a circuit by digitizing direct and transferring photography information to a camera side.  
     CONSTITUTION: For example, as distance adjustment ring 1 is rotated, rotating member 4 in the same body with guide pin 2, fit in groove 2 provided in the internal surface of ring 1, rotates through pin 2. Consequently, contact piece 7 pressed against the surface of code plate 6 fitted to the surface of member 4 transfers a digital value, which corresponds to a set distance, to a camera body side. A set aperture valve, etc., are the same and the simple constitution requiring no A/D converter, etc., transfers the set value digitally to provide the input transfer of photography information with high precision, so that proper exposure can be calculated and determined.

Title: Method and device for inspecting surface of disk
Inventor: TAKAHASHI IPPEI
IPC: G11B7/0037
Filed: 1988-06-13
Abstract: PURPOSE:To make light scattered on each scanning position almost uniformly incident on a light receiver by deviating the position of a scanning line from a line passing the center of rotation of a disk. CONSTITUTION:When the surface of an LVD(laser visual disk) 4 is irradiated with a light beam 3 by a scanner 2, a part of the light is absorbed by an optical absorbing body as regularly reflected light 3a. The scattered light 11 which is transmitted through a transparent layer 8, reaches a signal recording surface, is diffracted and scattered by a pit and becomes a circular arc-shaped pattern corresponding to the shape of the pit is projected from the surface of the LVD 4. Since the scanning line 5 is positioned by displacing the line passing the central axis 6 of the rotation of the LVD 4 in parallel by a distance l, the circular arc-shaped pattern is tilted as the scanning position becomes nearer to the inside. Most of scattered light 11 is made incident on the light receiver 7. If there is a flaw part S, an output from the light receiver 7 becomes the one to which the scattered reflected light from the flaw part S is added, thereby detecting it.

Title: Semiconductor laser device
Inventor: TAKIGAWA SHINICHI
IPC: H01L31/12
Filed: 1989-06-09
Abstract: PURPOSE:To enable a semiconductor laser device of this design to keep its optical output constant even if an atmospheric temperature changes by a method wherein the wavelength-dependent properties of the forward outgoing light ray and the backward outgoing light ray are made to cancel each other through the wavelength- dependent properties of a detector in sensitivity. CONSTITUTION:Both the projecting end and the rear incident end of a semiconductor laser are coated with Al2O3 and Si respectively. By this setup, the ends of the semiconductor laser are different from each other in reflectivity, so that light rays outgoing from the front end and rear end are different from each other at a prescribed wavelength, consequently the semiconductor laser shows wavelength-dependent properties. On the other hand, when the surface Si (PD) of a photodiode is coated with Al2O3, the photodiode displays transmittance wavelength dependent properties. At this point, when oscillation light changes in length, both the conductor laser and the photodiode show wavelength-dependent properties and change outgoing light rays. At this point, as the conductor laser and the photodiode become reflectivity wavelength dependent and transmittance wavelength dependent respectively and both the wavelength dependent properties cancel each other, a semiconductor laser device, which retains a constant optical output even if an atmospheric temperature changes, can be realized.

Title: Image forming device
Inventor: WATANABE JIYUNJI
IPC: G03G15/00
Filed: 1983-08-12
Abstract: PURPOSE:To discriminate on original size and to facilitate trimming by reading and displaying an original image on a display board. CONSTITUTION:A scanning optical system moves on the reverse surface of platen glass to scan on an original placed on its top surface, and projects its image upon the surface a photosensitive drum. The scanning optical system makes a preliminary scan on the original prior to said exposure process, and the original image is converted into an image electric signal by a solid-state image pickup array inserted into a projection optical path by rotation. This read is executed line by line, and the whole of the read original image is displayed on a liquid-crystal display board 76 through a latch circuit and display device driver. An additional lens is inserted right in front of the solid-state image pickup array on its rotation to eliminate the need to put the array right in front of the exposure area of the photosensitive drum. In practice, the array is set right behind a zoom lens of variable power. The image signal is converted into a binary signal to reduce the necessary memory capacity.
