Title: Optical-semiconductor device
Inventor: MORI MUTSUHIRO
IPC: H01L31/0232
Filed: 1980-11-14
Abstract: PURPOSE:To improve optical transmission efficiency and to obtain a composition which is hard to be broken by a method wherein a flexible optical coupling member is pressed and held between an end of an optical transmission line and a semiconductor element. CONSTITUTION:A silicone resin hemisphere 3 is pressed against a photodetecting surface 11 of a photo-thyristor substrate 1. The silicone resin is hardened easily without deteriorating the flexibility at an end 41 of an optical fiber. When the optical fiber which has the resin 3 at its end is pressed against the photodetecting surface, a region in which loss of the light is not reduced is obtained. With above configuration, manufacturing of the device is easy and a damage of a photodetecting surface of the optical fiber is eliminated, so that an optical semiconductor device with high efficiency of optical-coupling can be obtained.

Title: Organic nonlinear optical material
Inventor: KURIHARA TAKASHI
IPC: C07C67/00
Filed: 1987-06-29
Abstract: PURPOSE:To obtain an org. nonlinear optical material capable of executing nonlinear optical response at high speed and high efficiency by selecting an org. nonlinear optical material having small polarization in the ground state and regulating electron cloud in the excited state to have a center of symmetry. CONSTITUTION:The title optical material is expressed by formula I, wherein D is an electron donative group; at least one of R1 and R2 is a group other than H; Xn is 1-4 substituting halogen. Spontaneous polarization of the whole molecule is nullified by substituting both terminal atoms of a relatively long pi-conjugated molecule by strong doners having a same structure, and the charge density of the pi-conjugated part is increased in only the excited state by halogenating a central phenylene group. Thus, the difference of charge transfer between the ground state and the excited state is enlarged. By this constitution, decrease of response speed is prevented by preventing the absorption wavelength from transferring to long wave side, and great tertiary nonlinear optical effect is attained simultaneously.

Title: Shutter device
Inventor: YOSHIKAWA TAKASHI
IPC: G03B39/00
Filed: 1978-12-20
Abstract: PURPOSE: To make possible photographing of a vehicle running at high speed to be performed without blur, by providing parallel plane transparent material sheets which rotate in synchronism with the shutter, in the optical path between the photographic lens and the film.  
     CONSTITUTION: A photographic lens 4, a film 5, a shielding plate (case) 6 are disposed on parallel plane transparent material sheets 1 which rotate a certain angle in synchronism with a lens shutter 3 by means of a rotary solenoid 2. When the sheets 1 are in the state of 11, the light beam 71 from position P 1  runs straight to become means 73. A certain time later, the position P 1  moves to P 2 . At the same time, the parallel plane transparent material sheets 1 rotate until reaching the position shown by 12. At this point, the light beam 72 from position P 2  is refracted within the sheet 12 and is emitted as beam 73. That is, when the image of the object is moved from position P 1  to P 2 , the transmitted light can be moved from P 2 ' to P 1  by rotating the sheets 1, so that the motion of the image of the object may be rested relatively.

Title: High-speed ic package
Inventor: MIYAUCHI AKIRA
IPC: H01L23/552
Filed: 1985-07-19
Abstract: PURPOSE:To prevent the reduction of S/N by electromagnetically shielding the IC chip, bonding wire and lead wire on a substrate by multilayer ground wires, thereby greatly eliminating the inductive coupling between the input and the output. CONSTITUTION:The construction is such that ground layers 13, 14 are formed in a multilayer on a package substrate 15, and that a lead wire 12 is led through these ground layers 13, 14 to the package substrate terminal 16. With this, the IC chip 10, bonding wire 11 and lead wire 12 are electromagnetically shielded by the ground layers 13, 14. Therefore, the inductive coupling between the input and the output is greatly or almost eliminated, enabling the run-around of the signal to substantially be eliminated. As a result, oscillation and the reduction of S/N can be prevented.

Abstract: PURPOSE:To detect accurately an exposure to perform optimum light quantity control, by detecting an original scanning position to control the intensity of the light of an exposure lamp before irradiation of the original. CONSTITUTION:Slits 3 are so formed that lights of a pair of exposure lamps 1 cross each other in the same part on a platen 4. The light is reflected from the platen 4 onto a mirror 5 above the platen 4.

Abstract: PURPOSE:To make field of view bright, enhance distance measuring accuracy and yet enable sufficient quantity of light to be led to a photometric element by letting the orientation characteristics of the diffusion focal plate in the finder by rotation non-symmetrical. CONSTITUTION:In a camera having a finder optical system which forms the subject image on a diffusion focal plate with an image forming lens, the orientation characteristics of the diffusion focal plate are made rotation-non-symmetrical so that when the luminous flux of a small angle spreading from a dark lens of a large F number enters the rotation non-symmetrical diffusion plate 53, the distribution of the light emmitting from the diffusion plate 53 becomes such that the luminous flux is effectively led only to the eyepiece 55 and the photo detector 56 right thereabove and no light is diffused to other right-angle directions. The diffusion transmission to the direction of 14 to 15 deg. with respect to non-scattering light within the perpendicular plane is made larger by more than 10% than that in the horizontal plane, whereby good results are obtainable.
