Patent JP-S636844-A (JP)
Title: Manufacture of semiconductor device
Inventor: MATSUOKA NAOYUKI
IPC: H01L21/338
Filed: 1986-06-26
Abstract: PURPOSE:To decrease a side etching rate, by leaving a material for a gate also on chip regions other than the gate for the purpose of increasing the total amount of said material to create a substantial loading effect. CONSTITUTION:A high-melting metal compound 2 adhered on a compound semiconductor substrate 1 is dry etched with a resist 3 used as a mask. The high-melting metal compund 2 is thereby side etched by this etching operation. The side etching rate is about 300 m/min when a 300 mm thick tungsten silicide is used as a gate and NF3 is used as etching gas. This side etching rate can be decreased if tungsten silicide 5 is left also in other regions on the substrate 1. Accordingly, tungsten silicide 10 is provided for controlling the extent of side etching in addition to the tungsten silicide constituting the gate 7.

Abstract: PURPOSE:To evenly evaporate the metals of reforming components on surfaces and improve the rust preventive characteristic and corrosion resistance of the continuously annealed steel hoop by passing the steel hoop through a vapor deposition chamber of high temperature which is filled with metal vapors as reforming components in a reducing gas atmosphere. CONSTITUTION:The steel hoop 3 uncoiled from a pay-off reel R is passed through a vapor deposition chamber E by way of a cleaning device C and entry loop tower T, whereby reforming components such as Bi, Se, Te are evaporated on its surfaces, after which it is annealed in a continuous annealing furnace A. Reducing gas such as NH gas or AX gas is being supplied from the outside into the vapor deposition chamber E under the pressure higher than the atmospheric pressure so as to prevent entry of air. Reforming components such as Bi, Se and Te are being melted in a pot 7 provided with a heater and the vapors thereof are filling the inside of the reducing gas atmosphere having been heated to 220-1000 deg.C with a heater 9. The steel hoop 3 of low temperature enters the inside of the chamber by way of seal rolls 13 and the vapors of reforming component metals evenly evaporate on the surfaces of the steel hoop 3, thence the steel hoop enters the continuous annealing furnace A. The annealed steel hoop of superior rust preventive characteristic and corrosion resistance is obtained.

Title: Bus arbitration circuit
Inventor: KAWAGUCHI TADAHARU
IPC: G06F13/362
Filed: 1990-06-07
Abstract: PURPOSE:To easily change the priority when the bus using request signals received from plural data transfer modules are arbitrated by using a switch circuit and a preference circuit consisting of a memory storing plural priority patterns. CONSTITUTION:A request register 2 holds the bus using request signals REQ1 - REQn received from the data transfer modules M1 - Mn. A switch circuit 7 changes a priority pattern. A priority pattern store ROM 8 decides the priority of the bus using requests given from the modules M1 - Mn and uses the output of the circuit 7, an output ACK 112 received from a circuit 9 which shows either one of modules M1 - Mn can use a bus, and the output of the register 2 as addresses respectively. Then a bus use grant register 4 holds the bus use grant signals ACK1' - ACKn' received from the ROM 8. Thus a preference circuit 8 does not consist of hardware and the priority is easily changed.

Title: Differential pressure measuring instrument
Inventor: ASADA RYUZO
IPC: G01L13/06
Filed: 1992-06-09
Abstract: PURPOSE:To improve the welding yield of the instrument by using main body rings made of nickel or a nickel alloy and wetted diaphragms made of 'monel metal(R)', tantalum, or titanium. CONSTITUTION:When a pressure is applied to the title instrument from a high- pressure side, the pressure applied to a wetted diaphragm 38 is transmitted to a silicon diaphragm 8 through a sealing liquid 48. When a pressure is applied to the instrument from a low-pressure side, on the other hand, the pressure applied to a wetted diaphragm 37 is transmitted to the diaphragm 8 through a sealing liquid 47. As a result, the diaphragm 8 is bent in accordance with the pressure different between the high- and low-pressure sides and a strain gauge electrically fetches the bent amount of the diaphragm 8 and measures the differential pressure. Since ring-like main body rings 33 and 34 made of nickel or a nickel alloy are used, the rings 33 and 34 can be easily welded to the wetted diaphragm 37 and 38 made of Monel metal, tantalum, or titanium which are hardly weldable materials and the welding yield of this differential pressure measuring instrument can be improved.
