Title: Apparatus and method for cleaning semiconductor wafer
Inventor: SOSHIRO YUUJI
IPC: H01L21/304
Filed: 1989-05-16
Abstract: PURPOSE:To clean a wafer without occurrence of spot-like foreign materials and manufacture a highly reliable semiconductor device with high yield by a method wherein an exhaust pipe having a large diameter is placed on the bottom of a cleaning tank and an alcohol supply pipe is placed in the vicinity of the bottom respectively while pure water is discharged to be replaced with alcohol in a short time. CONSTITUTION:First a water supply valve 2 is opened to supply pure water to a cleaning tank 1 until the water overflows from the upper end into an exhaust tank 1a. Then a transfer basket 4 with a wafer 5 mounted is immersed and cleaned with water. After the specific resistance being 16MOMEGA.cm or larger (20 deg.C) is secured, the water supply valve 2 is closed and a drain valve 7 is opened to exhaust the pure water in the cleaning tank 1 immediately. As soon as drain of the pure water is completed, a supply valve 8 is opened to supply isopropyl alcohol solution. The speed for supplying isopropyl alcohol is specified so that it takes approximately 10 seconds for the solution to reach the upper part of the wafer 5. After the isopropyl alcohol solution completely having filled the cleaning tank 1 is assured, the transfer basket 4 is taken out. This method leaves no water drops on the surface of the wafer 5 and eliminates occurrence of spot-like foreign materials even through it takes time until the wafer is dried.

Title: Method of operating gas-turbine combustion equipment by dilute premix combustion system and device for stabilizing combustion in gas-turbine combustion equipment
Inventor: SUTEIIBUN EICHI BURATSUKU
IPC: F23R3/28
Filed: 1993-05-24
Abstract: PURPOSE: To keep combustion constant by a method wherein dynamic response characteristics in fuel and air supply systems for a gas turbine combustor are matched with each other. CONSTITUTION: As the result of a large pressure drop in a fuel passage occurring in an upstream orifice 52, the pressure in a response control cavitation 54 becomes practically equal to a compressor discharge pressure. When a pressure drop at a liner opening for supplying air to a premixing zone is the same substantially as a small pressure drop at a downstream orifice (gaseous fuel discharge orifice) 56, the respective phase angles thereof in relation to a pressure variation function are matched substantially with each other. By this matching of the phase angles, fuel and air flow responses are matched and therefore a fuel/air mixture ratio is kept constant substantially. Even when turbulence of pressure enhances the pressure in the premixing zone, the fuel/air mixture ratio is kept constant. Accordingly, a lean threshold frequency cycle is minimized substantially or removed.  As a result, combustion in a gas turbine combustor can be stabilized.

Title: Vibration-type semiconductor transducer
Inventor: ODOHIRA TETSU
IPC: G01L9/00
Filed: 1991-05-27
Abstract: PURPOSE:To achieve compactness by reducing the number of terminals for connecting a sensor capsule to a sensor amplifier and then reducing the number of hermetic terminals to be connected by commonly using a common portion of two vibrator main bodies. CONSTITUTION:Since a dimension of a vibrator main body 13 is different from that of a vibrator main body 14, an oscillation of these self-excitation circuits 64 and 65 is independently operated at oscillation frequencies f1 and f2, respectively. Therefore, no mutual interference occurs even if one edge of drive edges 21 and 29 of main bodies 13 and 14 is connected to common terminals 33A and 33B. Since a DC constant current IC flows to a temperature sensor 15, the terminals 33A and 33B can be connected. A silicon substrate 12 also be connected to the terminal 33A, thus enabling a sensor capsule 60 to be connected to a sensor amplifier 61 at connection terminals 32A and 32B, supply terminals 22A and 22B, detection terminals 18A and 18B, detection terminals 19A and 19B, supply terminals 30A and 30B, detection terminals 26A and 26B, detection terminals 27A and 27B, and the terminals 33A and 33B. These terminals are constituted as eight hermetic terminals.

Filed: 1986-05-27
Abstract: PURPOSE:To prevent an air cleaner from not being operated or being operated continuously, and to forcibly start or stop its operation, by enabling a normal operation mode, a forced operation mode with priority to the normal operation mode, and a forced stopping mode which forcible stops the operation of an air cleaner. CONSTITUTION:A first fan 21 is operated under a normal operation mode when it is initially energized and at the time of a normal operation. When a forced operation mode is selected, the fan is changed into a forced operation mode, with priority to the steady operation mode, but it automatically returns to the normal operation mode after a predetermined time has elapsed. A second fan 24 is operated for a predetermined short time only at the interval of a predetermined period. An air cleaner is intermittently operated under a normal operation mode, but it is changed into a forced operation mode by the depression of a button switch 26, and it is forcibleyoperated continuously for two hours afterwards. It returns to a normal operation mode after two hours have elapsed, so that it is not operated uselessly, but is operated efficiently and economically. The air cleaner is frocibly stopped for two hours when it is changed into a forced stopping mode by the depression of a button switch 26, but automatically returns to a steady operation mode after two hours, accordingly, such a situation that the air cleaner is not at all operated can be prevented.

Filed: 1982-07-13
Abstract: PURPOSE:To permit the exact judging of knocking at all times by a method wherein a judging value for judging the existence of the knocking is learned in an operating zone in which the knocking is not being generated, in the method in which the basic ignition timing is corrected in accordance with the existence of the knocking. CONSTITUTION:During operation, a digital control circuit 46 operates the basic ignition timing based on the outputs of an airflow meter 14 and a rotating angle sensor 42 and corrects the basic ignition timing by the correcting amount of knocking, in which the spark angle of the engine is delayed by a predetermined amount, when it is judged by a knock sensor 44 that there exists the knocking. On the other hand, a basic injection amount is corrected by the knock correcting amount, in which the spark angle is advanced by a predetermined amount, when it is judged that the knocking is not existing. In such an ignition timing control method, the judging value for judging the existence of the knocking is learned in an operating zone, in which the knocking is not being generated, by integrating the outputs of the knock sensor 44.

Title: Deciding method for sensor output abnormality
Inventor: WATANABE MASANORI
IPC: G01D5/12
Filed: 1995-05-22
Abstract: PURPOSE: To quickly decide abnormality while preventing misjudgement by more shortening a time required for deciding a sensor output as abnormal, as difference between the sensor output and a threshold is larger. CONSTITUTION: When the absolute value of the difference between the sensor output VPV of a steering torque sensor and an upper limit and a lower limit thresholds VH, VL are obtained as departure degree (d) and an abnormality judgement time (t) corresponding thereto is retrieved, if the time (t) is determined as t4 at a T2 points, a timer starts, and if the time (t) is determined as t3 at a T3 point, the timer restarts. After the T3 point, if the departure degree (d) settles between d2 and d3 , the time (t) becomes up at a TE3 point after the lapse of t3 time so that the output VPV is decided as abnormal confirming the same so as to stop the control of assist force. In this case, when the output VPV is close to the threshold VL (VH), the time (t) is set slightly longer, and is set shorter as parting from the threshold VL (VH).  Therefore, when the steering torque sensor is lost, the abnormality of the output VPV can be decided early so that the control of the assist force can be stopped early.
