Title: High frequency circuit
Inventor: SUZUKI TAKUYA
IPC: H01P5/02
Filed: 1999-11-17
Abstract: PROBLEM TO BE SOLVED: To solve the problem that the reflection characteristics of high frequency signal deteriorate significantly at the joint of a multilayer high frequency package and an external circuit because resonance takes place at a frequency where the difference of electrical length between the current of a high frequency signal and a ground current is equal to about a quarter of the wavelength of the high frequency signal or integer times thereof when the ground current flows through the ground through hole in the high frequency package. SOLUTION: At the joint of a microstrip line pattern and the external circuit of a multilayer high frequency package, the substrate member 1aa of a first dielectric substrate 1a and a microstrip line pattern 2a on the outer surface are placed on the inside of a first ground conductor 4a. Consequently, a ground current 11 can be connected through a shortest distance by placing a connection substrate 104 between the multilayer high frequency package 101a and the external circuit 101b resulting in a high frequency circuit having good reflection characteristics in which occurrence of an undesired propagation mode is prevented.

Filed: 1992-11-14
Abstract: PURPOSE:To manufacture a necessary number of core cylinders in a short time through the operation in a line, by joining the edge part of a batten plate which is bent by a direction change roll. CONSTITUTION:A batten plate A is placed on a material table 11, and then horizontally slided so that the top edge of the strip plate A is bitten between pinch rolls 12 and 13. When a handle is turned, the strip plate A collides with a gudie 16a, and direction is changed, and the strip plate A is dropped downward, forming a curl on the strip plate A between the direction change roll 15 and the lower pinch roll 13. Then, the interval between the fixed drum piece of a joining board and a movable drum piece is reduced, and a bendable plate A1 having a curl is inserted between both the drum pieces and a material pressing part. Then, the interval of both the drum pieces is spread to obtain the necessary diameter. The bendable plate A1 having a curl is joined. Accordingly, a necessary number of strip-shaped coil core cylinders can be manufactured in a short time through the operation in a line.

IPC: G21K5/02
Filed: 1997-11-28
Abstract: PROBLEM TO BE SOLVED: To provide an X-ray inspection device capable of changing the amount of energy over a wide range by one unit.

Title: Manufacture of members for nuclear power plant
Inventor: FUJIWARA TETSUO
IPC: G21C21/00
Filed: 1991-12-13
Abstract: PURPOSE:To restrain radioactive corrosion products from being increased in reactor water by heat-treating members under the decompression environment of a specified degree of vacuum after solution annealing has been given, and thereby giving age hardening treatment and oxide film formation treatment to the members. CONSTITUTION:In manufacture of members for a nuclear reactor composed of Ni group precipitation consolidated type alloy, the members are heat-treated under the decompression environmental pressure of 10<-3> to 10<2>Torr after solution annealing has been given, and age hardening treatment and oxide film formation treatment are then given to the members. The reason why the decompression environmental pressure for heat-treatment is limited to 10<-3> to 10<2>Torr, coarse oxide articles will be produced over the surface of an oxide film if pressure is equal to or more than 10<2>Torr, and the oxide film strong enough to restrain elution of Ni can not be formed if pressure is less than 10<-3>Torr. In addition, temperature for heat-treatment shall be ranged from 600 deg.C to 730 deg.C. This restraint thereby allows elution of Ni to a nuclear power plant to be lessened, and also allows <58>Co, that is, radioactive corrosion products flowing to reactor water to be reduced accordingly, thereby making works easy at the time of periodic inspection and repairs, so that availability factor is thereby enhanced.

Title: Governor valve opening fixation control method
Inventor: OKADA TAKAO
IPC: F01D17/10
Filed: 1990-11-30
Abstract: PURPOSE:To perform a characteristic collection in a short time accurately by determining an optimum controlled variable for canceling interference among control devices against a manipulated variable from the outside of a turbine equipment which is operated in control of speed and pressure, and rapidly converging a governor valve operation. CONSTITUTION:A turbine measuring point is determined in a turbine characteristics collection function 1 to output a target governor valve opening. The target governor valve opening is inputted to a control error calculation process 2 to determine its difference from a present governor valve opening. The control error becomes a governor valve opening manipulated variable by performing a PID arithmetic 3 and an inner non-interference arithmetic 4. The governor valve opening manipulated variable is converted to a pulse manipulated variable which is outputted to a drive edge motor by a pulse manipulated variable arithmetic 5, and is outputted to a load adjusting device or a pressure adjusting device. Consequently, a turbine control device 6 side can control the governor valve independently without its modification so as to acquire accurate characteristics data in a short time for the purpose of the turbine characteristics collection.
