Title: Hydrostatic bulge forming method of shell
Inventor: ARAKI JINICHIROU
IPC: B21D26/033
Filed: 1978-09-14
Abstract: PURPOSE: To form protrusions with good workability without using any female dies by beforehand forming the intended molding portions of a shell of hollow inside thinner than the non-molding portion and letting liquid pressure be acted from the inside.  
     CONSTITUTION: Both end openings 4, 4 of a tubular body 3 provided with thin- walled portions 2, 2 are hermetically sealed with axial load dies 5, 5 and high pressure working fluid 6 is force fed into the tubular body 3. The liquid pressure 6a of the fluid 6 causes the thin-walled portions 2, 2 to bulge outward in annular form, whereby, e.g. a bellows 7 is hydrostatic bulge formed.

Title: Handy color scanner device
Inventor: OKADA YOSHINOBU
IPC: H04N1/107
Filed: 1999-04-20
Abstract: PROBLEM TO BE SOLVED: To obtain an image of high quality which is close to the hue of an original by correcting a line deviation at every color by means of execution in two steps according to the scanning speed of a handy color scanner device. SOLUTION: The image sensor unit of three-color RGB-LED light source changing system is used in a handy color scanner device. In this case, if the speed for reading one-primary color image data for one line is adopted as T (second), it takes a time of 3T in order to read data of three RGB color information. Furthermore, the handy scanner can continuously read image data for one line at every 3T. Moreover, the scanning speed is detected by two steps from a signal from an encoder for outputting a pulse signal, according to the scanning line for the portion of one pixel and from the number of image lines to be read in one pulse signal. The line deviation by RBG is correction- processed according to the scanning speed which is detected by two steps.

Title: Bipolar transistor
Inventor: TAKEMURA HISASHI
IPC: H01L29/732
Filed: 1990-04-28
Abstract: PURPOSE:To form a stable emitter electrode without increasing an emitter resistance even when an emitter area is made fine by a method wherein a silicon carbide film and a polycrystalline silicon film are formed only on the bottom face inside an opening formed in an insulating film. CONSTITUTION:When individual layers are formed on a P-type silicon substrate 1, a silicon carbide film 12 is formed only on the surface of an epitaxial layer 3 inside an opening part surrounded by a sidewall insulating film 11 and a polycrystalline silicon film 13 is formed only on the film 12. The film 12 and the film 13 which are formed on an emitter region 14 are buried and installed inside the opening surrounded by the film 11 on a base region 10, and are not formed substantially on the side and the surface of the film 11. As a result, the film thickness of the film 13 and the film 12 which are arranged between an upper-part aluminum electrode 15 and the region 14 becomes uniform, and arsenic atoms which are implanted into the individual films are distributed uniformly. Thereby, it is possible to avoid that an emitter resistance is increased and to make the film 13 for emitter electrode fine. Even when an emitter area is made fine, the emitter resistance is not increased and a stable emitter electrode can be formed.

Abstract: PURPOSE:To largely reduce the write time of an ROM by enabling the write of contents in the ROM device by the addition of the process of injecting the same conductivity type impurity as source and drain regions. CONSTITUTION:The part of a gate insulation layer 181 is implanted the same conductivity type impurity as that of source region 15 and drain region 16, i.e., P type impurity, and the surface of an Si substrate 11 is doped with the P type impurity, resulting in the formation of P<+> type impurity regions, i.e., the first impurity regions 24 and 25 respectively. Since these regions 24 and 25 work as a part of the source region 15 and drain region 16, an actual working IGFET is constituted. On the other hand, the part of a gate insulation layer 182 is implanted the reverse conductivity type impurity to that of the source region 15 and drain region 16, i.e., N type impurity, and the surface of the Si substrate 11 is doped with the N type impurity, resulting in the formation of N type impurity regions, i.e., the second impurity regions 26 and 27 respectively. Since these regions 26 and 27 have N conductivity type which is reverse to that of the source region 15 and drain regions 16, only non working IGFET is constituted.

IPC: A61H23/00
Filed: 1990-04-27
Abstract: PURPOSE:To secure a higher filtering capacity while operation in filtering can be recognized simply and clearly by turning an air control valve to a opening position while a reflux water control valve to one jet nozzle is turned to an opening position when a quick filtering mode is specified. CONSTITUTION:When a quick filtering mode is set, a sequence control shifts an air control valve 4 and one reflux water control valve 9a to an opening position while the other reflux water control valve 9b is turned to a closing position. The air control valve 6 is opened fully, the reflux water control valve 9a is turned to an interrupted opening and the reflux water control valve 9b is closed fully. There is no spouting of a jet flow from a jet nozzle 3b on the opposite side to a suction port 2. A jet flow Ja spouted from a jet nozzle 3a on the side where the suction port 2 exists reaches a side wall on the opposite side to the suction port 2 from a central part of a bath tub 1 and detours here to cause a large convection Wc extending to the suction port 2 passing the underside of the central part of the bath tub 1 by water W0 in the bath tub. Thus, contamination of the water W0 in the bath tub can be taken out of the suction port 2 efficiently to undergo a filter processing.

IPC: B24B9/00
Filed: 1987-05-09
Abstract: PURPOSE:To enable polishing a plate material at all times under a proper pressure by monitoring the condition of contact between a grindstone and a plate material in a direct polishing process, and causing the grindstone to come near and off the plate material on the basis of a signal generated from a contact pressure between the grindstone and the plate material. CONSTITUTION:An ammeter A is set for monitoring an electric current flowing to a motor 12 for driving a polishing grindstone 10, and the range of electric currents (proper range) flowing when the polishing grindstone 10 rotates in contact with a plate material under a proper pressure is examined preliminarily. In this condition, the polishing grindstone 10 is fed toward the plate material while rotating at the predetermined speed and made in contact with the plate material to be polished. Then, the value of electric currents read on the ammeter A increases and when the value reaches the upper limit of the proper range as set, the rotation of a motor 14 is reversed on the basis of a signal from the ammeter A. And a grindstone support bed 11 is thereby moved upward and the polishing grindstone 10 is moved away from the plate material. On the contrary, when the current value reaches the lower limit of the proper range, the motor 14 is made to turn continuously in a normal direction and the polishing grindstone 10 is continuously fed to the plate material.
