Title: Electric motor driven blower
Inventor: ATSUMI HIROTO
IPC: F04D29/44
Filed: 1980-12-26
Abstract: PURPOSE: To decrease noise and improve effeciency by preventing swirling of the airflow without increasing the size of the whole structure by installing a guide mechanism to forcibly change the air flow, induced through air inducing hole, in the direction parallel to the rotational shaft.  
     CONSTITUTION: When air flow having swirling force component tends to flow in the case 1 through air inducing hole 8, the air flow flows in the direction parallel to the rotating shaft 3, while colliding with the bumping wall 11 installed in the vicinity of air introducing hole 8. Therefore, airflow A in the case 1 does not swirl, generates no vortex accompanied with swirling flow and the noise can be suppressed to a lower level. Swirling dynamic pressure can be converted to static pressure by existence of the bumping wall 11 therefore, the efficiency can be also improved. And in this case the above explained effect can be obtained by only adding simple guide mechanism in the case 1. Accordingly, the whole size of the blower will not be enlarged.

Inventor: IMAI YUJI
IPC: H01L21/306
Filed: 1987-07-25
Abstract: PURPOSE:To make it possible to control an etching angle by a method wherein an etching is performed by electrolytic etching and the liquid temperature of an electrolyte and the current density of an electrolytic current are adjusted. CONSTITUTION:A wafer 1 is dipped in an electrolyte 5 in an etching tank 4 in a state that it is held by a clip 2 and a cathode plate 6 is connected to the negative electrode of a power source E and is dipped in the electrolyte 5. An etching that takes place by electrolytic etching is progressed while an electrolytic current is controlled in such a way that the value of the electrolytic current becomes a constant value. In performing the electrolytic etching, an etching taper angle can be controlled at an arbitrary value by adjusting properly the liquid temperature of the electrolyte and the current density of the electrolytic current. Accordingly, an etching surface F, which is at angle of 90 deg. (alpha=90 deg.) to the main surface of the GaAs wafer 1, can be formed by the electrolytic etching.

Title: Manufacture of thin-film semiconductor device
Inventor: TAKENAKA SATOSHI
IPC: H01L21/336
Filed: 1999-06-30
Abstract: PROBLEM TO BE SOLVED: To form an excellent gate oxide film by a method wherein a silicon thin-film is formed onto an insulating amorphous material, the silicon thin-film is inserted into an oxidizing furnace, the temperature of the silicon thin-film is elevated up to a fixed oxidizing temperature at the specific speed of a temperature rise and the gate oxide film is formed. SOLUTION: The temperature Ta of a silicon thin-film-inserting oxidizing furnace is set to 600 deg.C, and a substrate reaches the center of an oxidizing furnace at a time t1. The speed of substrate insertion is set so that the speed of a temperature rise of a substrate surface reaches 20 deg.C/min at that time. The temperature of the oxidizing furnace is increased up to an oxidizing temperature Tb at the speed of the temperature rise of 20 deg.C/min or less. Tb is set normally at 900 deg.C or higher at the time of dry oxidation, but the silicon thin-film is oxidized slowly even when the silicon thin-film is inserted at a low temperature of 600 deg.C because the speed of oxidation is increased at the initial stage of oxidation. The substrate surface reaches a specified oxidizing temperature Tb at a time t2 by elevating the temperature of the oxidizing furnace.  An extremely excellent gate oxide film can be formed at Tb=1150 deg.C.

Abstract: PURPOSE:To suppress an excess current at the time of start of electrification and prevent the cracking of an insulator by supplying a fixed current value to a ceramic heater by a control means when a detected current value is raised to a set value or more. CONSTITUTION:When an ignition switch 82 is on, the operation of a microcomputer 9 is started, and a switching circuit 801 is on when the water temperature of the cooling water of an internal combustion engine is lowered less than a set value. As this ceramic heater 7 has a very small electric resistance value at ordinary temperature, an excess current flows thereto when the voltage of a battery 81 is directly applied at the time of start of electrification, and the current value of the ceramic heater 7 read from an ammeter 84 becomes a set value or more. Thus, a switching circuit 802 is on, a switching circuit 803 is off, the ceramic heater 7 is subjected to constant current control at a determined current value by a constant current circuit 86. Thus, the excess current never flow to the ceramic heater 7, and the cracking of an insulator 2 by a thermal shock is prevented.
