Title: Controller for current type converter
Inventor: HOKARI SADAO
IPC: H02M7/5387
Filed: 1987-03-24
Abstract: PURPOSE:To obtain continuous output characteristic, by generating DC voltage and counter DC voltage on the positive and negative ones, in the same chopping period, to cancel the DC voltage of output generated when a current type converter is chopper-worked with the pulse width made minimum. CONSTITUTION:So far as the controller of a current type converter 2 is concerned, when operation command 11 is generated, then a speed pattern is generated from an operation controlling circuit 12, and by the speed pattern and the speed feedback signal 91 of an encoder 9, arithmetic is performed on a vector, and the output of current command I ' and frequency command f' is generated. By a current controlling circuit 13, from the current command l' and the feedback current Iaf of a current detector 10, a control deviation Ei is found, and the output is directed to a current type converter controlling circuit 14. By the controlling circuit 14, the control deviation Ei is received, and driving signals P201-P204 are generated. As a result, by the current converter 2, chopper- working is performed, and the constant voltage of a storage battery 1 is turned into variable voltage and the output is generated, and DC power turned into the variable voltage is fed to an inverter 4.

Title: Vertical liquid damper
Inventor: TATSUMI EIJI
IPC: E04H9/02
Filed: 1988-03-22
Abstract: PURPOSE:To attenuate the vibration in the vertical direction by supporting a weight onto a body filled with liquid in shiftable ways through an elastic means and installing a resisting member for suppressing the flow-out in a bypass passage which is formed on the side of a weight and connects the upper and lower spaces of the weight. CONSTITUTION:When a weight 7 suspension-supported through springs 9 and 10 inside is shifted in the direction of arrow B in a weight passage 3, a liquid 5 is pushed, and flows into a bypass passages 11 and 11 from a mesh 6, and further flows upwardly, and flows into the weight passage 3 in the upper part of the weight 7. In this case, a mesh 12 for suppressing flow-out is installed in the bypass passage 11, and acts to suppress the shift of the weight 7 in the B-direction. The weight 7 is shifted in the A-direction in similar process, and the liquid 5 suppresses the vibration of the weight 7 in synchronization with the vibration in the vertical direction of all installation object article 13, and the phase of the vibration deflects from that of the installation object article 13. Therefore, the vibration of the installation object article 13 and the vibration energy of the weight 7 can be offset, and the vibration of the installation object article 13 can be effectively attenuated.

Title: Method for installing fluid control valve in non-water failure state and sealing connection device therefor
Inventor: TAKAMURA TSUYOMICHI
IPC: F16L55/18
Filed: 1990-03-19
Abstract: PURPOSE:To prevent a cut part from rusting by setting a process wherein a fixed connection ring is previously mounted in a spot where a fluid control valve is installed, a process wherein after a fluid pipe is cut by a cutter, the fluid control valve is inserted in a cut part, and a process wherein a moving connection ring is engaged in a watertight manner with the fixed connection ring. CONSTITUTION:In a closed case S, a fluid pipe P is cut in a straight tubular shape by means of a cutter H. A fluid control valve V is then inserted in a cut part Q, and installed in a non-water failure state. In this method, fixed connection rings 1 are mounted on both sides of the peripheral surface of the fluid pipe P and a spot where the fluid control valve V is installed. After the fluid pipe P is cut by means of the cutter H, the fluid control valve V having an expandable coupling ring 2 for wrapping a sealant 22 mounted in a contracting state is inserted in the cut part. The expandable coupling ring 2 is engaged in a watertight manner with the fixed connection ring 1. This constitution cuts off a flow in the fluid pipe P, resulting in prevention of the occurrence of rusting starting from a cut surface.

Title: Method for inversion of pattern
Inventor: ASAI SHUJI
IPC: H01L21/3065
Filed: 1985-04-02
Abstract: PURPOSE:To prevent the variation of pattern size by using a silicon nitride film in which a hydrogen concentration is under a specified value. CONSTITUTION:A pure nitride film in which a hydrogen concentration is 3atm% or under is used for an inverted pattern in order to improve an etching-resistant property of a nitride film on a temporary pattern boundary. For example, a temporary pattern 2 made of an oxide film 1.0mum thick is formed on a substrate 1. Next, silicon is sputtered in a mixed gas of argon and nitrogen to be covered with a pure nitride film 3 of 0.3mum thickness. A hydrogen concentration of a sputtered nitride film is 0.1atm% or under. A resist film 5 is spread and is dried. The whole surface is etched by the parallel electrode type dry etching using CF4 gas so as to expose the upper part of the temporary pattern 2 from the nitride film 3, after which the residual resist film 5 is removed by an organic solvent. When the temporary pattern made of an oxide film is removed selectively by etching using a buffered hydrofluoric acid, an inverted pattern 6 of the nitride film 3 is left on the substrate 1.

Title: Manufacture of copper barrier type coated pipe
Inventor: SHIMADA YOSHIO
IPC: C23G5/032
Filed: 1979-06-06
Abstract: PURPOSE:To manufacture the copper barrier type coated pipe whose copper surface is less decolored by a procedure in which the coated pipe is washed with water, then its inside is washed with a hydrophilic volatile organic liquid, and lastly the pipe is dried by warmed air or inert gas. CONSTITUTION:The coated pipe 1 is washed with water and its copper surface is soon washed with ethyl alcohol 2 supplied while its inside is still wet. The washing with ethyl alcohol is made by flowing the ethyl alcohol while rotating the coated pipe or by filling ethyl alcohol in the coated pipe and then flowing it out. After the washing with ethyl alcohol, warmed air or argon gas is forcibly flowed into the coated pipe from its one end or both sides alternately to vaporize ethyl alcohol adhered to the surface. The drying temperature is regulated to 100 deg.C or less because the copper is liable to be oxidized at 100 deg.C or more in the air.

Title: Processing system of directivity synthesis
Inventor: TSUKADA KENJI
IPC: G01S7/526
Filed: 1995-03-28
Abstract: PURPOSE: To obtain a processing system by which an arithmetic processing amount is compressed when the directivity in the near sound field of a vertical wave-receiving array used to detect an underwater sound source is to be synthesized. CONSTITUTION: When the directivity of a vertical line array 5 in a near sound field is to be synthesized, sound waves are treated as spherical waves, and the directivity is synthesized so as to be directed to a plurality of virtual sound sources. Since the synthesis processing operation is performed over the entire near sound field by successively varying the positions of virtual sound sources, the processing amount becomes enormous. An area computation part 4 finds an area of the near sound field excluding a region which can be handled as plane waves in advance, and the area is supplied to a delay-time computation part 1a. The delay-time computation part 1a computes a time delay for directivity synthesis in the area and a time delay for directivity synthesis with reference to a sound field other than the area, and the time delays are supplied to a delay phasing part 2.  Thereby, the directivity is synthesized, and an output is detected by a detection part 3 so as to be output.
