Patent JP-S5972772-A (JP)
Title: Semiconductor device
Inventor: UENOYAMA TAKESHI
IPC: H01L27/08
Filed: 1982-10-19
Abstract: PURPOSE:To reduce the area occupied by a complementary circuit in an integrated circuit, by combining the channel regions of junction type field effect transistors vertically in two stages. CONSTITUTION:In the gate region of a junction type field effect transistor, a different conductive type channel region for another junction type field effect transistor is provided, and the potential of both gate regions are made equal. For example, in order to separate the upper and lower junction type field effect transistors, a voltage to be applied to terminals 31 and 33 is made smaller than the built in potential of a P-N junction. The impurity concentration of gate regions 36 and 37 are determined in the following way: when a low potential is applied to the input terminal 33, a channel region 34 becomes a pinch off state, and a channel region 35 becomes a conductive state; and when a high potential is applied, the channel region 34 becomes a conductive state, and the channel region 35 becomes a pinch-off state. The structure, wherein the channel regions are vertically provided in two stage, is effective in constituting a complementary circuit, wherein two element can be included in the area, in which only one element is included beforehand.

Abstract: PURPOSE:To increase the bonding strength between a multilayer electrode and an insulating film by providing a nitride film layer between the junction region of an electrode layer and the insulating film constituting a lower layer. CONSTITUTION:After each region is formed on an Si substrate by a method known publicly, plasma SiN is connected onto the whole surface, photoetching is applied thereon, and thereby an SiN film 1-3 is formed in a junction region. Next, windows are opened selectively in an SiO2 film 1-2, Pt is connected thereto, and heating is made at the temperature of 500 deg.C. Thereafter, Pt which has not reacted is removed by aqua regia, and thereby connection layers 1-11-1-12 are formed of Pt-Si. Subsequently, Ti and Al are superposed thereon to prepare layers 1-13 and 1-14. According to this constitution, there is SiN between the SiO2 film 1-2 and Ti of the lowermost layer of a metal electrode, and thereby the strength of bonding with Ti is improved. Therefore, the strength of the junction region against exfoliation is increased, and there is not ununiformity in the strength nearly at all. Mo or Ti.W is also effective in addition to Ti.

Title: Method for hydroformylation
Inventor: TANO KAZUO
IPC: C07C45/50
Filed: 1982-10-21
Abstract: PURPOSE:To separate a rhodium catalyst in an active state and recirculate the separated catalyst for use, by adding a trivalent organic phosphorus compound to a hydroformylation reaction solution obtained in the presence of a catalyst consisting of Rh and the above-mentioned organic phosphorus compound, and oxidizing the resultant undistilled portion containing the Rh. CONSTITUTION:An olefinic compound is reacted with water gas in a catalytic solution containing rhodium and a trivalent organic phosphorus compound, e.g. an arylphosphine oxide or alkylphosphite oxide, to give a hydroformylation reaction solution. A trivalent organic phosphorus compound in an amount of 1-20 P atoms based on one Rh atom in the solution is then added thereto, and the resultant mixture is distilled and separated into an undistilled portion consisting of a high-boiling fraction containing Rh and a distillate. The above-mentioned undistilled portion discharged as the bottom residue is oxidized (usually by blowing air under atmospheric pressure) to convert the trivalent organic phosphorus compound into an oxide, which is used as a catalytic solution for the hydroformylation process. The above-mentioned distillation carried out in the presence of oxygen provides the simultaneous oxidation, and the undistilled portion is usable directly as the catalytic solution.

Title: Bearing metal material and rolling bearing
Inventor: MIKAMI EISHIN
IPC: F16C33/12
Filed: 1997-07-10
Abstract: PROBLEM TO BE SOLVED: To make improvements in a frictional characteristic on boundary lubricating conditions, reducing each individual variation in the frictional characteristic on the working conditions of high temperature and high speed, and to prolong the bearing life by forming a thionic acid metallic salt coat on the surface of a bearing metal material. SOLUTION: Those of bearing steel, case hardened steel and high-speed steel as raceway materials, and blanked cage sheet steel, machined cage carbon steel or the like as cage materials are enumerated. A rolling bearing which applies and charges lubricating oil and grease on the inside is used, and a lubricant is such consisting of liquid and semi-solid ones provided with the specified revolution and heat resistance, therefore mineral oil, polyphenylether or the like are listed up as well. The formation of a thionic acid metallic salt coat on a bearing surface is carried out after it is dipped in a solution of thionic acid ether, and then grease and lubricating oil are applied and charged onto the frictional surface.  As the abovementioned, even in such a boundary lubricating condition where an oil film is used up, sulfuric lubricating matter out of the coat is held on the frictional surface, enhancing its lubricity, and metals themselves will in no case come into contact with one another, and besides, there is less in each individual variation in a frictional characteristic, and thus bearing life is stabilized and it is prolongable for hours.

Title: Method for reducing amount of cyanogen in gold alloy plating solution
Inventor: TOGAWA EIJI
IPC: C25D3/48
Filed: 1982-10-22
Abstract: PURPOSE:To control simply the concn. of free cyanogen in an alkali cyanide type gold alloy plating soln. contg. a weakly alkaline carbonic acid compound as a pH buffer when plating is carried out in the soln. using an insolube anode, by blowing oxygen into the plating soln.

Title: Shutter device for electron microscope
Inventor: OI KORO
IPC: H01J37/20
Filed: 1985-08-23
Abstract: PURPOSE:To facilitate opening/closing of shutter through simple structure thus to block the electron beam and secondary electrons reliably by rotating a fluorescent board through a holding board to open/close an iris through a shutter while arranging the iris of fluorescent board and the hole of holding board on/off the optical axis. CONSTITUTION:Upon driving of motor to rotate a shaft 16, a holding board 13 will rotate thus the rotate a fluorescent board 11 from position A to C. Upon arrival to the position A, the shutter 21 will stop through engagement of stopper 26 with the housing 17 while engage with the engaging section 27 of holding board 13 to close the iris 12 and the hole 14 by the shutter under this condition thus to face the carbon 23 against the hole 14 and the iris 12 and the hole 14 are shifted from the optical axis 3 and never aligned. Consequently, the electron beam 28 is blocked by the shutter 21 and never passes to the underside thus to enable observation on the fluorescent board 11. Since the shutter 21 will move with self-weight in reverse direction from the rotary direction of fluorescent board 11, it has simple structure to cause scarce fault. Since rotation of fluorescent board 11 will cause alignment of the iris 12 and the holes 14, 19, the operation is simplified.
