Title: Manufacture of semiconductor device
Inventor: SHINOHARA MAMORU
IPC: H01L21/8249
Filed: 1989-05-25
Abstract: PURPOSE:To increase the breakdown strength between two kinds of buried layers by a method wherein an impurity in the inverse conductivity type to that of a semiconductor substrate is diffused from the windows of nitride films and then the semiconductor substrate is heated while another impurity in the same conductivity type as that of the semiconductor is diffused from oxide films. CONSTITUTION:After side etching oxide films 22b using nitride films 23a as masks, the second conductivity type impurity is ion-implanted in a semiconductor 21 to form impurity layers 24 and then while activating the impurity in the impurity layers 24, the first conductivity type impurity is diffused in the semiconductor substrate 21 from the oxide films 22b. In order to achieve the said purpose, two kinds of buried layers 24b, 25a in different conductivity type are formed i.e. respectively from the second conductivity type layers 24 and the first conductivity type impurity layers 25 diffused from the oxide films 22b containing the first conductivity type impurity on the semiconductor substrate 21 by one time photolithographic process. Through these procedures, the buried layers 24b, 25b can be restrained from forming stepped parts by controlling the concentration thereof thereby enabling the breakdown strength between these two kinds of buried layers 24b, 25a to be increased.

Title: Controlling method for pressurized atmosphere furnace and the same furnace
Inventor: SUZUKI AKIRA
IPC: F27D19/00
Filed: 1989-05-24
Abstract: PURPOSE:To prevent excess temperature rise of a gas discharge tube by detecting the surface temperature of the tube when pressurized gas is discharged from a pressure vessel, stopping and restarting discharge of gas based on the detected surface temperature, and controlling a temperature in a furnace. CONSTITUTION:A controller 32 closes a gas discharge valve 10 to forcibly stop discharge of gas when the surface temperature of a gas discharge tube 9 detected by temperature detecting means 31 exceeds a set value T0 if a furnace is cooled therein, i.e., if a heater 5 is OFF. When the temperature is lowered by DELTAT from the set value T0, the forcible stop is released to restart the gas discharge. When the detected temperature value of the tube 9 exceeds the value T0 if the furnace is heated therein, i.e., if the heater 5 is ON, the gas discharge is forcibly stopped and the heater 5 is simultaneously turned OFF to stop heating. When the detected temperature value is lowered by DELTAT from the set value T0, the gas discharge and heating are restarted. Thus, the excess temperature rise of the tube can be prevented.

Title: Method of increasing fuel at the time of cancelling "fuel cut" in electronically controlled fuel injection engine
Inventor: ISOBE TOSHIAKI
IPC: F02D41/12
Filed: 1983-07-18
Abstract: PURPOSE:To prevent deterioration of the engine performance at the time of cancelling ''fuel cut'', by detecting the level for judging the degree of drop of the engine speed that is lowered when the degree of change of the engine load is high, and correcting the injection quantity of fuel to increase the same when the degree of drop of the engine speed is higher than the above judging level. CONSTITUTION:In an engine shown in the drawing, the synchronous injection quantity of fuel is calculated by an ECU40 from the engine load and the engine speed detected respectively from the outputs of a sensor 22 for detecting the pressure in an intake pipe and a crankangle sensor 36, and operation of an injector 26 is controlled synchronously with rotation of the engine. Further, when judgement is made that the engine is in deceleration, ''fuel cut'' is effected by stopping synchronous injection of fuel. At the time of cancelling ''fuel cut'', judgement is made whether or not the degree of change of the pressure in an intake pipe per one rotation of the engine is higher than a reference level. In case of YES, a relatively small value is used as the level for judging the degree of drop of the engine speed so as to faciitate fuel incresing correction. In case that the judgement is NO, on the other hand, a relative large value is used as the above judging level so as to hinder fuel increasing correction.

Title: Laminated molding and its manufacture
Inventor: EGUCHI HISASHI
IPC: B29C47/02
Filed: 1997-05-21
Abstract: PROBLEM TO BE SOLVED: To provide a laminated molding which shows low stretching properties and high heat resistance, light weight and is free from the possibility of rust generation and further, is suited for application as an architectural member to be used outdoors, especially in a rain gutter and a method for manufacturing the laminated molding. SOLUTION: This laminated molding is of such a structure that the front/back of a sheet S comprising an inorganic short fiber C oriented at random with thermoplastic resin are coated with an extruded thermoplastic resin and a sheet S reinforced in every direction with the inorganic short fiber C with a low coefficient of linear expansion as a core material whose front/back are wrapped with the thermoplastic resin P. Thus the laminated molding is hardly susceptible of the generation of a deformation, a crack or a warp by heat due to a direct solar radiation. When manufacturing the laminated molding, a continuous sheet S is made by continuously pressing thermally and cooling under pressure a continuous mat made of a mixture of the inorganic short fiber and the thermoplastic resin.  Then the sheet is shaped to the required form, and at the same time, the front/back of the sheet are coated with the extruded thermoplastic resin as a core material. Thus it is possible to obtain the laminated molding of a desired type easily and efficiently.
