Title: Scavenging device for 2-cycle internal combustion engine
Inventor: TSUJIMURA KUROTAKA
IPC: F02B75/02
Filed: 1979-12-03
Abstract: PURPOSE: To prevent blowing over of gas at the initial stage of opening of a scavenging port by providing a check valve, which allows air flow toward inside of a cylinder from a scavenging chamber only, at an inlet end of an upper scavenging port of a device with upper and lower scavenging ports in a cylinder liner.  
     CONSTITUTION: When a piston 5 descends and an upper scavenging port 21 opens, a lead valve 23 tightly adheres to a valve seat 24 to close an air passage 24a in case that pressure in a cylinder 111 is higher than that of a scavenging chamber 6, so that backward flow (blowing over) of gas in the cylinder to the scavenging chamber 6 can be prevented. When the piston 5 further descends and pressure in the cylinder 111 becomes lower than that in the scavenging chamber 6, the lead valve 23 is opened by the differential pressure and is pressed against a stopper 25, fresh air in the scavenging chamber 6 flows into the cylinder 111 through an upper scavenging port 21. When the piston 5 further descends, a lower scavenging port 22 also opens to let fresh air flow into the cylinder 111.

Title: Ic wafer checking automatic prober
Inventor: YAMASHITA NAOMI
IPC: G01R31/26
Filed: 1988-06-24
Abstract: PURPOSE:To shorten a setting up time and an indexing time of a wafer at probing by a method wherein the deviation between an IC wafer and a probe is automatically adjusted when the IC wafer is set to an automatic prober. CONSTITUTION:An automatic prober is made to store a deviation theta between an IC wafer 1 and a probe 2. Therefore, the wafer 1 has rotated by the deviation theta between the IC wafer 1 and the prober 2 when the IC wafer is loaded under the probe 2, so that the position of the IC wafer 1 is coincident with that of the probe 2. If an index value at probing is obtained, the index value of a chip A is, for instance, x' and y'. As the index value x' and y' change simultaneously, the traveling time of the prober 2 to the next chip is a time required for the prober to move along either x' or y' longer than the other. Therefore, the index time becomes short.

IPC: C21B9/14
Filed: 1982-09-10
Abstract: PURPOSE:To perform combustion at high pressure, by a method wherein high blast gas is fed through a blast furnace gas feed pipe branched from the front stage of a furnace top pressure gas turbine. CONSTITUTION:A system is constituted such that a part of blast from a blower 70 with a slightly large capacity is supplied through a combustion air pipe 130, and a heat exchanger 110 for high pressure is additionally mounted on a flue duct 9 to preheat a combustion air flowing through the combustion air pipe 130 by use of high-pressure exhaust gas. Through working of a pressure reducing valve 130a, pressure of the combustion air pipe 130 is made equal to that of a blast furnace gas feed pipe 140. High-pressure combustion is effected within a combustion chamber 2B, and because of improvement of combustion efficiency within a combustion chamber 2B, combustion exhaust gas is still at sufficient temperature although its temperature is slightly lower than a previous exhaust gas temperature, and the pressure thereof is high. Thereby, heat energy of said exhaust gas is fairly high even after it is partially consumed in the heat exchanger 110, whereby a waste heat recovery turbine 200 is installed, and after a generator 200' is operated by means of the exhaust gas, the exhaust gas is exhausted through a chimney 10.
