Title: Enhancement type insulated gate transistor
Inventor: NISHIZAWA JUNICHI
IPC: H01L29/78
Filed: 1987-10-13
Abstract: PURPOSE:To reduce minority carrier storage effect, and improve frequency characteristics with large gm, by a method wherein a depletion layer extending from a drain region is put so close to a source region that punching through is apt to occur, and the width of the narrowest part of a second semiconductor region is set as a specified value. CONSTITUTION:The following parameters are determined so as to satisfy equations I and II; distance l between a source 41 and a drain 43, width W of a p-region in the vicinity of a source, and impurity concentration of the p-region. In the equations, epsilon is the dielectric constant of semiconductor, q is elementary electric charge, Vb1 is diffusion potential between the p-region and a region 42, and Vb2 is diffusion potential of n<+>-p<-> junction. Even if a second depletion layer extending from the drain 43 reaches the source 41 and generates punching through, the potential of an intrinsic gate (barrier) can be made so high that carrier does not flow into a second depletion layer from the source by the effect of the first depletion layer extending from a p-region 44. Thereby the operation of an enhancement type punching through transistor is enabled.

Abstract: PROBLEM TO BE SOLVED: To instantly measure pinholes in a film quantitatively and non- destructively in a simple manner by scanning an insulating film with light beam through an electrolyte, and measuring electric charges present in the electrolyte which comes in through the pinholes of the insulating film. SOLUTION: A frame-like member 4 is placed on an SOI substrate 1, and after it is lidded with a window member 3, an electrolyte 2 is fed in the frame- like member 4 by a pump, with the SOI substrate 1 filled with it over its surface.

Title: Polarized light generation device
Inventor: TAKABAYASHI HIROBUMI
IPC: G21K1/093
Filed: 1990-09-26
Abstract: PURPOSE:To prevent drop of beam energy by arranging the X-direction mag. field distribution of magnet magnetized in the + or -Y directions of each train of magnets alternately in the Z-direction so as to be higher to one side of the + or -X directions. CONSTITUTION:Two sorts of magnets 14a, 14b magnetized in Y-direction constituting a train 10 of magnets have constant thickness (Y-direction) and (Y-direction) in the same manner as other magnets 13a, 13b, but their width (Z-direction) varies to the length (X-direction), and the + or -Y directions as magnetizing direction are made opposite to each other alternately when arrangement is to be performed. That is, magnet 14a magnetized in -Y direction is designed enlarged in the +X direction, so that the X- direction mag. field distribution has a characteristic inclined higher to the +X direction and -also because magnet 14b magnetized in the +Y direction is designed wider in the -X direction, the X-direction mag. field distribution has a characteristic inclined higher to the -X direction end. When an electron beam passes between the upper and lower trains of magnets, the inclining direction of the mag. field distribution inclined higher to one side end of X-direction appears as oppositely directed alternately if viewed in the Z-direction, so that the electron beam is prevented from diffusion to make better convergence, which leads to reduction of possible loss of the beam energy.

Filed: 1998-09-11
Abstract: PROBLEM TO BE SOLVED: To realize a reduction of an electric power loss and a small size by generating an ignition current using an acceleration switch comprising a semiconductor type acceleration switch. SOLUTION: At the time of generation of a collision accident, when a collision judging means 10' judges a generation of a serious accident based on an acceleration signal from an acceleration sensor 9, a transistor 17c is turned on by an ignition signal, a control transistor 14e is turned off, first and second switch circuits 5, 7 are turned on and a current flows in a resistance 14b and a pre-driver 14d. As a result, a 100 times constant current flows in one squeeve 6 in a transistor of the first switch circuit 5 as an ignition current. The collision judging means 10' outputs the former ignition signal, turns the transistor 14e' off and turns switch circuits 5', 7' on. As a result a current control circuit 14' operates similarly to a current control circuit 14 to flow the ignition current in a squeeve 6'.  At this time, the transistor 14e formerly turned off is turned on and the first switch circuit 5 is turned off.

Title: Rolling bearing and corrosion resistant film forming method for rolling bearing
Inventor: TOYODA YASUSHI
IPC: F16C33/66
Filed: 1996-09-30
Abstract: PROBLEM TO BE SOLVED: To improve protection against corrosion and attain a long life by forming a solid corrosion resistant film of a fluorine-contained polyurethane high molecular compound on the exposed surfaces of components. SOLUTION: The solid corrosion resistant films 5 of a fluorine-contained polyurethane high molecular compound are formed on the whole surfaces of of inner/outer rings 1 and 2, a rolling element 3 and a cage 4. Because the solid corrosion resistant films 5 have very fine three-dimensional reticular structures and are densely coated on an object to be coated, corrosive components becomes difficult to permeate the solid corrosion resistant films 5. Furthermore because the solid corrosive films 5 are excellent in lubricity and dusting characteristics such as difficulties in generating exfoliation and abrasion due to a small frictional resistance at the time of the rolling/sliding between each component of a rolling bearing A, rolling/sliding operations can be stabilized for a long period and cleaning of using environments can be contrived.

Title: Semiconductor memory
Inventor: SAKAI YOSHIO
IPC: H01L27/10
Filed: 1984-12-10
Abstract: PURPOSE:To obtain the memory cell composed of a short channel MOS transistor of high speed which is capable of enhancement of integration by surrounding the MOS transistor of the memory cell with the region of high impurity concentration than that of the substrate. CONSTITUTION:Both of N-channel and P-channel transistors are formed in wells 23 and 24 comprising higher impurity concentration than that of a substrate 22. Accordingly, in each transistor, imfluence of electric field fro a drain upon a channle region is diminshed and if a channel length of the transistor is 5mum or under, decline of a breakdown voltage or a thereshold voltage due to punch- through phenominon hardly occurs. Furthermore, a threshold voltage of thick field oxide films 34, 35 and 36 in the wells becomes about 20V or above because the transistors are present in the wells of relatively high impurity concentration and generation of a parasitic MOS transistor can be prevented without forming a guard band.
