Title: Method for cleaning surface of pulverized metal powder
Inventor: TAKAGI SHINOBU
IPC: B22F1/00
Filed: 1991-01-29
Abstract: PURPOSE:To prevent the coagulation of metal grains and to maintain flowability in a superior state by dispersedly incorporating specific amounts of long-chain fatty acid into a pulverized metal powder and exerting reduction treatment at specific temp. at the time of applying surface cleaning to the pulverized metal powder by means of reduction treatment with hydrogen. CONSTITUTION:At the time of subjecting a pulverized powder of metal (Cu, Ag, etc.) to reduction treatment with hydrogen to perform surface cleaning, long-chain fatty acid (oleic acid, stearic acid, etc.) or its metallic salt is incorporated, in a dispersed state, into the pulverized metal powder by 0.05-10% and reduction treatment is done at 150-5O0 deg.C. By this method, surface treatment can be performed while effectively inhibiting the coagulation of mutual grains of the pulverized metal powder.

Title: Manufacture of compound semiconductor device
Inventor: HAGA TORU
IPC: H01L21/338
Filed: 1989-02-10
Abstract: PURPOSE:To prevent the deposition of polycrystal grain of a mask on a mask by a method wherein a part of the mask is covered with a mask whose diffusion length is longer than the mask, and selective growth is performed by making the distance from the inside of the left mask to its peripheral selective growth layer smaller than the diffusion length of compound semiconductor on the mask. CONSTITUTION:Gate electrodes 10, 11 are made of heat-resistant Schottky metal. In SiO2 films 20, 20', windows for a source and a drain are formed on both sides of the gates, and an N<+> GaAs layer 30 is obtained by selective growth using MOCVD (organometallic chemical vapor deposition). The WSix gate electrode 11 is covered with the SiO2 film 20' because the deposition of GaAs polycrystal grain generates. The gate electrode 10 part is subjected to selective growth as it is, since the distance to the peripheral GaAs growth part is 1mum or less, and then the SiO2 film 20' covering the WSix gate electrode 11 is eliminated. After that, ohmic metal is deposited on the source.drain part, and wiring is formed. Thereby, an MESFET LSI can be manufactured without deposition of polycrystal grain.

Title: Hydraulic cylinder drive circuit
Inventor: HIGUCHI TOORU
IPC: F15B20/00
Filed: 1978-03-15
Abstract: PURPOSE: To reduce the area of a cylinder by applying hydraulic pressure only to one port of the cylinder at normal time and hydraulic pressure from a pressure accumulating tank to the other port of the cylinder when supplied hydraulic pressure is lost.  
     CONSTITUTION: When hydraulic fluid is normally supplied from a supply port D, a valve is operated as shown in Figure to supply hydraulic pressure only to the port 1a of a cylinder so as to retain the piston 6 at one stroke end. If hydraulic fluid is not supplied to the supply port D due to some reason, an exhaust valve 2 is switched to the position 2b and a trip valve 3 is switched to the position 3b. Thus, hydraulic pressure in a pressure accumulating tank 5 is supplied to the port 1b of the cylinder to move the piston 6 rightwardly. Limit switches 14, 14' are then opened to switch the valves 7, 8 so as to open a conduit B with the atmosphere.

Title: Semiconductor nonvolatile mos memory
Inventor: MORIYAMA ICHIRO
IPC: H01L29/792
Filed: 1989-02-09
Abstract: PURPOSE:To prevent erroneous reading of data and an increase in power consumption by forming an impurity diffused layer of two elements which are one having large electric field concentration and the other having small electric field concentration to be used as a drain at the time of reading. CONSTITUTION:An impurity diffused layer 13 of a terminal C side of two impurity diffused layers is formed in a LDD structure. That is, the layer 13 of the terminal C side is formed of a 2-layer structure of an N<-> type layer 15 having low N-type impurity concentration at its gate side and n a N<+> type layer 16 having high N-type impurity, connected to the N<-> type layer. An impurity diffused layer 14 of a terminal B side is formed only of a normal N<+> type layer having high impurity concentration. In case of reading after negative charge is stored (written) at a floating gate 2, the layer 13 is used as a drain, and a positive voltage for reading is applied to the terminal C. In this case, since the impurity concentration of the layer 15 is low, a concentration of the electric field near the drain can be alleviated. Thus, it can prevent carrier for causing a leakage current. Therefore, the leakage current can largely be reduced.
