Filed: 1995-09-08
Abstract: PROBLEM TO BE SOLVED: To stably control a device without largely changing a temperature and pressure even if a temperature and pressure of a steam separator reduce in ordinary operation by using a heating circulating pump by reducing rotating speed at rotating time for power generation more than rotating speed at starting time. SOLUTION: A heating circulating pump 9 continuing with a heating circulating system 6 has a VVVF inverter to variably control rotating speed in a driving power source, and is selected so as to be used at low rotating speed in power generating operation. Therefore, even when electric power is generated, a circulating quantity of a trace quantity is always circulated in the heating circulating system 6, and since inside cooling water is held at almost the same temperature with potential water 31 of a steam separator 3, even when heating operation is performed by the heating circulating system if a situation where a temperature and pressure of the steam separator 3 reduce is caused, a situation where a temperature and pressure largely change since low temperature cooling water flows in is avoided, and a device is stably controlled.

Title: Spread spectrum communication system and spread spectrum receiver
Inventor: OHASHI TSUTOMU
IPC: H04B1/713
Filed: 1997-08-27
Abstract: PROBLEM TO BE SOLVED: To improve the security of information by limiting an opposite party to provide information depending on its content and a kind. SOLUTION: A transmitter applies spread spectrum processing to a communication signal by the frequency hopping system to generate a spread signal and to make transmission. On the other hand, a viewer receives the spread signal and applies inverse spread processing to decode an original communication signal. In this case, the viewer generates the spread code used for inverse spread processing based on a password received by an input section 370. Thus, only when a correct correlation is entered, the spread code used by a transmitter side is coincident with a spread code used by the viewer and normal inverse spread processing is conducted at the viewer side.

Filed: 1987-09-17
Abstract: PURPOSE:To suppress a false gap effect by forming a magnetic metallic thin film after removing an oxide magnetic material so that this material is not parallel with a high-melting point glass surface filled in grooves. CONSTITUTION:Track width prescribing grooves 2 are provided on a substrate 1 consisting of an oxide magnetic material, and a high-melting point glass 4 is filled in grooves, 2, and its upper face 4a is ground into a plane.

Title: Three-dimensional composite clean valve
Inventor: HOCHIDO YUKO
IPC: F16L41/02
Filed: 1988-09-14
Abstract: PURPOSE:To remarkably facilitate cleaning of a residual liquid or gas by uniting three valves into one body in one block to remarkably reduce the length of piping and remarkably reducing a liquid sump portion. CONSTITUTION:Three valves 1 - 3 adopting a bellows valve are united into one body in one block, the vale 1 is formed very close to piping A and the valve 3 is formed very close to piping B. Cleaning operation is conducted by closing the valves 1, 3, opening the valve 2, vacuum-sucking one opening of A and B and letting inert gas flow through the other opening thereof. By this operation, a space between the valve 1 or the valve 3 and a cleaning piping is made very small, so that a liquid sump is hard to produce in that portion. Even if a liquid sump is produced, the quantity is very small, so that residual liquid can be easily blown off by vacuum suction and blowing of inert gas. Thus, particles due to hydrolysis of residual liquid are not produced to remarkably decrease the particle density.

Title: Scroll hydraulic machinery
Inventor: HIDANO KATSUSHI
IPC: F04C18/02
Filed: 1998-08-03
Abstract: PROBLEM TO BE SOLVED: To improve sealing performance of the compression chamber by providing a seal ring which rotates between the easing and the rotational scroll. SOLUTION: In a casing 2, a rotational scroll 8 is provided opposing to a fixed scroll 4. This rotational scroll 8 is rotated by a driving shaft 5 or the like. Between the casing 2 and the rotational scroll 8, a seal ring 16 is disposed, of which the inner periphery is offset respective to the outer periphery. When the rotational scroll 8 is in rotational motion, the seal ring 16 is rotated in the casing 2, while it is relatively moved in the outer periphery side of the rotational scroll 8. As a result, lubricant 3 in a easing 1 is prevented from entering any compression space 9 between an overlapping part between 4D and 8B.

Title: Method and apparatus for detecting defect of insulated wire
Inventor: TADA HIROYUKI
IPC: G01R15/18
Filed: 1996-08-30
Abstract: PROBLEM TO BE SOLVED: To detect a defective part of the conductor of an insulated wire under active state by feeding an AC current to the conductor, detecting a generated field through a field detecting means while converting into a voltage and then detecting the difference between two detected voltage and determining the magnitude thereof. SOLUTION: When an AC current is fed uniformly to each conductor 2 of an insulated wire 1, a constant voltage is induced in a detection coil 4a and the potential difference between the connecting terminals 5 of a coil 4 substantially goes zero. When one conductor 2 is broken or a stress corrosion crack is present in the conductor 2, current is distributed unevenly and the center of current distribution is shifted from the center O of the wire 1 to point P. A relatively large voltage is induced in a coil 4a having a short distance to the point P whereas a relatively small voltage is induced in a coil 4a at the opposite position and a potential difference (e-f) is detected. Consequently, a defect, e.g. stress corrosion crack of the conductor 2 can be detected by measuring the potential difference of a pair of coils 4a, comparing the potential difference with that of another pair of coils 4a and determining the ratio of AC current of the conductor 2.

Filed: 1984-11-05
Abstract: PURPOSE:To form a fine pattern of high quality, which is free from under cut and also an etching residue by using a reactive gas to which a gas consisting of a halogen gas except F2, as a main component, and containing an F2 gas or a fluorine compound has been added. CONSTITUTION:In case of a well-known electron cyclotron resonance (ECR) reactive ion etching, F2 or a fluorine compound such as SF6, etc. is mixed to a halogen gas whose main component is Cl2, etc. except F2 and it is used as a reactive gas. That is to say, an etching reaction is promoted by fluorine which is scarcely influenced by impurities of atmosphere, and also a compound of fluoride and chloride having a higher boiling point is formed as an etching reaction product, by which the etching reaction product is removed smoothly. According to such a method, a fine pattern of high quality and high accuracy can be formed with high controllability on an electronic device substrate.

Title: Inspection method for sound generating body
Inventor: MATSUDA SHIGERU
IPC: G01H3/00
Filed: 1995-08-17
Abstract: PROBLEM TO BE SOLVED: To judge whether the sound generated from a sound generating body by applying a shaking force of specified basic frequency is acceptable or not quantitatively. SOLUTION: A shaking force of a specified frequency is applied to a sound generating body to generate a sound and the sound pressure level thereof is sampled for a predetermined time and the sampled data is subjected to FFT operation to obtain a spectral data. Maximum peak frequency is than detected along with the number of peaks and valleys and the frequency of each detection value is determined basedon a membership function for judging the acceptableness being set for each detection item. Subsequently, a correction frequency is calculated by weighting each frequency depending on the degree of importance of judgment and it is judged whether the sum of correction frequencies is higher than a specified threshold level thus judging the acceptableness of a sound generating body. Consequently, a quantitative judgment can be made without relying upon the audition.
