Title: Cleaning method
Inventor: HIRANO YOSHIO
IPC: H01L21/306
Filed: 1991-07-26
Abstract: PURPOSE:To easily clean an object to be cleaned, such as a semiconductor substrate, etc., in a short time by treating the object with a low-viscosity liquid chemical after treating the object with a high-viscosity liquid chemical, and then, washing the object with water in the manufacturing process of a semiconductor device. CONSTITUTION:In the manufacturing process of a semiconductor device, an object to be cleaned getting wet with a high-viscosity liquid chemical is treated with a low- viscosity liquid chemical after the object is treated with the high-viscosity liquid chemical and the adhering low-viscosity liquid chemical is then washed away with water. At the time of removing, for example, the nitride film of a semiconductor substrate, the substrate is first treated with hot phosphoric acid which is the high-viscosity liquid chemical in a hot phosphoric acid tank 11. As a result, the nitride film is removed from the surface of the substrate and the phosphoric acid adheres to the surface. Then the substrate is dipped in nitric acid which is the low-viscosity liquid chemical so as to replace the phosphoric acid with the nitric acid. As a result, the nitric acid adheres to the surface of the substrate. Thereafter, the substrate is dipped in pure water in a water washing tank 13. Since the adhering nitric acid easily dissolves in water, the water washing can be completed in a short time with a small amount of pure water.

Title: Device for preventing cavitation of recirculating system pump for reactor
Inventor: KURODA YOSHIHIRO
IPC: F04D15/00
Filed: 1985-08-26
Abstract: PURPOSE:To prevent cavitation from taking place by always monitoring reactor pressure and the flow rate of feed water by means of a cavitation detecting mechanism, and outputting a cavitation notifying signal to a preventing mechanism. CONSTITUTION:Reactor pressure and the flow rate of feed water are always monitored by a cavitation detecting mechanism 131 which outputs a cavitation notifying signal 136S based on a feed-water flow-rate detecting signal from a feed-water flow-rate detector 134 and a reactor pressure detecting signal from a reactor pressure detector 133. And, when there is a possibility of cavitation taking place, a cavitation notifying signal is outputted to a cavitation preventing mechanism 132. Based on said notifying signal 136S inputted via a controller 141, the prevention mechanism 132 outputs a recirculation flow rate varying signal 144S from a reactor recirculation flow rate varying circuit 143 to reduce or adjust reactor recirculation flow rate. Thereby, by detecting the possibility of cavitation taking place, the recirculation flow rate is adjusted to prevent cavitation from taking place.

Patent JP-S6166600-A (JP)
Title: Excitation regulator of ac generator
Inventor: SHIOZAKI YASUSHI
IPC: H02P9/30
Filed: 1984-09-06
Abstract: PURPOSE:To improve the response characteristic of a generator for a voltage variation by flowing an electric energy stored in the field of a generator to a series circuit of a diode and a resistor in synchronization with the OFF period of a chopper. CONSTITUTION:Since a signal from an automatic voltage regulator 10 is OFF when the voltage of a generator is high, a chopper transistor 6 is OFF to supply no current to a field coil 8. Since a current stored in the coil 8 is flowed through a diode 12 to a resistor 13 due to OFF auxiliary chopper transistor 7, it is attenuated, and the time constant of the coil 8 during this period apparently becomes short. Thus, the jump of the voltage at the voltage variation time and hence at full load interruption time can be suppressed.

Abstract: PURPOSE:To realize the strict filing management by receiving an discrimination code and at the same time storing the data information and the discrimination code together with the file name when the read of the file information is designated. CONSTITUTION:A personal computer is used for information processing to record and store the input produced file information into a table file, etc. Then the discrimination code is received by a nameplate device 2 incorporating a communication equipment from a portable compact transmitter 1. While the discrimination code stored previously is automatically originated by an optical signal, an ultrasonic wave, etc. When an operator performs the key operation to read out the file information via the transmitter 1, the operator code received by the device 2 and the present data information obtained from a timepiece 3 are recorded into a memory means 4 together with the relevant file name when the read is designated. Thus it is possible to know accurately the name of a user, the access time point and the access file information by checking later the contents of the means 4.
