Patent JP-H0661477-A (JP)
Title: Semiconductor device and its manufacture
Inventor: HANAKURA MITSURU
IPC: H01L29/06
Filed: 1992-08-10
Abstract: PURPOSE:To adjust the width of a base layer and that of a buffer layer and at the same time provide a short-circuiting layer for short-circuiting an anode emitter for achieving a high breakdown voltage in a bevel-machined semiconductor device where the sectional area increases from a high-resistance semiconductor layer side toward a low-resistance semiconductor layer side. CONSTITUTION:A high-concentration N-type impurity concentration is diffused to a low-impurity concentration N-type silicon wafer 21 extremely thinly for forming a diffusion layer 22 and at the same time the surface of a specific region from the outer-periphery part of the diffusion layer 22 toward the inner part is etched extremely thinly and then an epitaxial growth layer 23 is formed on the diffusion layer 22 in a GTO (gate turn-off thyristor). Then, the diffusion layer 22 is extended by a long heat treatment for thinning the above specific region and achieving a low concentration. After that, an N-type emitter layer 14, a P-type base layer 15, a P-type emitter layer 12, and an N-type short- circuiting layer 16 are formed by selective diffusion. A positive bevel 20 whose sectional area is changed is formed on the semiconductor layer which is formed in this manner, thus obtaining the GTO whose electric field strength characteristics are improved.

Title: Optical scanning device
Inventor: YANAGISAWA MICHIO
IPC: G02B26/10
Filed: 1987-08-26
Abstract: PURPOSE:To eliminate the need for an expensive ftheta lens and to correct the curvature of field, by driving an actuator with a reference signal generated with a pulse signal from a motor which rotates a polygon mirror. CONSTITUTION:Pulses of an encoder fitted to a motor 505 are processed by a reference signal generating circuit 507 to generate a rectangular wave with synchronism of T seconds. A BPF 508 processes it and the actuator 506 is driven through a power amplifier circuit 509. The modulation of a laser 502 is performed by passing a recording signal and a synchronizing signal from the motor through a modulating circuit 501 for equal pitch correction on a scanning surface because ftheta is not used. The actuator is constituted by fixing a permanent magnet 403 and auxiliary magnetic poles 404 and 405 outside the holder 402 for a collimator lens CL 401 and then interposing rubber materials 409 and 410 between support springs 406 and 407 and a yoke 408 and coupling them elastically with a yoke. Coils 411 and 412 are fed reversely with electricity to control force operating on the permanent magnets, thereby displacing the CL finely. This constitution uses a polygon mirror 504 with plane reflecting surfaces to correct the curvature of field, thus obtaining the optical scanning device which is easily adjusted.

Filed: 1987-08-26
Abstract: PURPOSE:To obtain a low cost device and to obtain a sharp image having a high contrast by providing a ferroelectric material layer subjected to an orientation treatment on an electrode on an insulating substrate. CONSTITUTION:The ferroelectric material 14 which consists of a copolymer of VDF and FrFE and is subjected to a rubbing treatment is provided on the electrode 13 on the insulating substrate 12 and an electrode 15 consisting of Cr is formed thereon. A prescribed upper substrate is stuck to this lower substrate 12 and a liquid crystal is sealed therebetween to form the active device. Since the ferroelectric material layer 14 is used as an orienting layer in such a manner, the stage is simplified and the low cost device is obtd. The device holds the electric field impressed to the liquid crystal not by the time constant of the liquid crystal itself but by the spontaneous polarization of the ferroelecric material 14 and, therefore, the disappearance of the image by the leak current of the liquid crystal itself is obviated and the sharp image having the high contrast is obtd.

Filed: 1999-07-27
Abstract: PROBLEM TO BE SOLVED: To grasp the degree of satisfaction of a user by evaluating the information showing the degree of an acquired service state according to a received evaluation standard and calculating a satisfaction degree index that shows the degree of satisfaction of the user about the service quality. SOLUTION: A service quality calculation/evaluation part 105 monitors continuously a network and at the same time monitors whether the service supply time that is measured by a measurement counter exceeds the time that is defined by a quality evaluation interval. When the service supply time exceeds the defined time, the service availability is calculated for every service that is defined by a quality evaluation model according to the contents which are contained in a level transition history table. Then the part 105 evaluates the service quality from the calculated service availability and an SA evaluation policy that is contained in an SA evaluation policy table. Thus, the service quality is measured, calculated and evaluated according to the mutual agreement of service levels.
