Patent JP-S63118121-A (JP)
Title: Image processor
Inventor: SATO HIROSHI
IPC: H04N1/19
Filed: 1986-11-06
Abstract: PURPOSE:To prevent a lens array from having an irregularity in pitch (irregularity in light quantity) by providing diffusibility to the reverse surface of a Fresnel lens used as a field lens. CONSTITUTION:A Fresnel surface 51 is formed on the top surface of the Fresnel lens 5 as the field lens, and a diffusing surface 52 which has fine unevenness is formed on the reverse surface on the opposite side from it. Luminous flux exiting from the exit pupil 31 of a projection device 3 is refracted by the Fresnel surface 51 on the top surface of the Frensel lens 5 and converted into parallel luminous flux, which is diffused by the diffusing surface 52 on the reverse surface. Namely, the spread angle alpha on the enlargement side of the projection lens is increased by said diffusing surface 51 as shown in a figure beta so that beta.alpha. Therefore, an irregularity in the quantity of light resulting from that the spread angle K of the projection lens is smaller than the aperture angle theta of the lens array is eliminated by providing the reverse surface of the Fresnel lens 5 such diffusibility that beta>=theta.

Title: Electric-hydraulic converting device
Inventor: FUJIMOTO MASAHISA
IPC: F16K31/04
Filed: 1985-11-25
Abstract: PURPOSE:To ensure safety in case of power loss, by providing a spring reaction removing means for canceling a reactive force of a spring to a change nut provided on an output shaft of planetary gears. CONSTITUTION:A rotary motion of stepping motors 1 and 2 is transmitted through a planetary gear 51 to a screw shaft 24. The screw shaft 24 provides for a linear motion to a change nut 25 having a stopper 26 to control an output oil pressure of an electric-hydraulic converter in proportion to a compressive force of springs 43 and 44. A lever 39 is branched at a lower end portion of a hook 40, and is connected to the change nut 25 by a screw. Even when the stepping motors lose a restrictive force upon power failure, the change nut is restricted by the operation of the hook to be hindered from rising, thus maintaining a controlled oil pressure just before the power failure.

Title: Medium exchange management system for data library device
Inventor: TOKI MITSURU
IPC: G06F3/08
Filed: 1985-11-27
Abstract: PURPOSE:To inhibit the delivery of the mounting/demounting instruction that is inapplicable to an optical disk library device during the exchange of optical disk cartridges, by deciding automatically that those cartridges are under displacement. CONSTITUTION:A host computer 1 delivers the control to an OLU control program 5 in order to mount a desired optical disk cartridge 9 out of a cartridge storing part 8 to a disk drive mechanism 10 or to demount the cartridge 9 to set it back to the part 8 in case the job using an optical disk library device 7 is executed. The program 5 searches an OLU control table 6 which controls the state of the device 7 prior to the instruction for mounting/demounting actions and checks a display flag for the exchange of cartridges. If this flag is set, it is displayed, for example, that the mounting/demounting actions are impossible with cartridges since an operator is exchanging the cartridges.

Title: Optical isolator
Inventor: MAKIO SATOSHI
IPC: G02B27/28
Filed: 1988-10-21
Abstract: PURPOSE:To increase a backward direction loss and to prevent the deterioration of a semiconductor laser by polishing the faces which allow the transmission of an optical axis among the faces of the polyhedral body of a polarized light separating element to specular surfaces and disposing materials to absorb the separated light to at least one face of the other faces. CONSTITUTION:The two faces perpendicular to the optical axis, i.e. faces 11a, 11b which allow the transmission of the optical axis are polished to the specular surfaces and the materials 13a, 13b which absorb the separated light are disposed to the two faces 12a, 12b, through which the light totally reflected and separated by the polarizer are transmitted, among the four faces parallel with the optical axis. The light passing these faces are, therefore, mostly absorbed by the materials 13a, 13b and the probability that the separated light from the polarizers 3a, 3b passes the optical path decreases drastically. Return light 7 to the semiconductor laser side decreases drastically as well. The backward direction loss of the optical isolator is increased in this way and the deterioration of the semiconductor laser is prevented.
