Title: Driving device for superconducting magnet
Inventor: HIRANO MASARU
IPC: H01F6/00
Filed: 1987-11-06
Abstract: PURPOSE:To smoothly adjust an electric power amount by controlling an ignition angle upon switching of an ignition angle command value by a power control rectifier. CONSTITUTION:When a superconducting magnet 1 is in a superconducting state, the current value of a DC current flowing to the magnet 1 is detected by a current detector 5. The detector 5 forms a signal corresponding to the current value, and an ignition angle switching unit 6 applies an ignition angle command value to a phase controller 4 in response to the signal. A phase controller 4 receives the command value from the unit 6, and operates a power control rectifier 2 with the ignition angle corresponding to the command value in the AC waveform of a power source. Thus, the AC current is converted to a DC current by the rectifier 2 used for the magnet 1. In this manner, the power amount is smoothly adjusted.

Title: Resistance diffusion joining method
Inventor: INOUE SHINICHIRO
IPC: B23K20/00
Filed: 1990-10-19
Abstract: PURPOSE:To simplify a resistance diffusion joining device without requiring an auxiliary electrode by vertically compressing and energizing two members through brazing filler metals. CONSTITUTION:When the 1st members abut on Cu electrodes 4, 5 and the brazing filler metals, since the intervals between the respective surfaces are comparatively large, Joule heat enough to melt the brazing filler metals can be held. Further, silver and tungsten electrodes do not abut on the 2nd members but the corresponding 2nd members abut on them and whenever the resistance diffusion joining is completed, the members are always changed to new ones, therefore, the electrodes need not be polished to remove oxide films. Consequently, the resistance diffusion joining device can be simplified and, further, since the man-hour for maintenance can be reduced, the productivity can be improved drastically.

Title: Gas carburizing method
Inventor: NANBA KEISHICHI
IPC: C23C8/20
Filed: 1984-12-31
Abstract: PURPOSE:To decrease the uneven carburization owing to the intergranular oxidation and the shape of material to be treated in particular and to provide an economical gas carburizing method which does not require a conversion furnace by supplying only the gas which is required for carburization and from which N2 is expelled into a furnace in which a temp. is maintained at a prescribed temp. or above. CONSTITUTION:Gaseous hydrocarbon such as CH4 and pure oxygen are introduced into the furnace maintained at >=730 deg.C, by which N2 is expelled and the atmosphere necessary for the carburization is formed. The material to be treated is carburized in such atmosphere. More specifically, CO is generated by the reaction of the hydrocarbon and pure oxygen like formula and the [C] generated from the decomposition of said CO on the surface of the material to be treated penetrates and diffuses into the surface of said material. The fluctuation of the partial pressure of CO by the N2 which does not contribute directly to the carburization as in the conventional practice is thus obviated and the uneven carburization is decreased. The intergranular oxidation is thereby obviated as the inside of the furnace is kept at above the above-mentioned temp. and the pure oxygen is introduced therein without using H2O, CO2, etc.

Title: Test method of logical circuit and test device of logical circuit
Inventor: NISHIDA KOJI
IPC: G01R31/28
Filed: 1998-10-02
Abstract: PROBLEM TO BE SOLVED: To always accurately judge whether or not short circuit failure is caused in an external terminal of an integrated circuit. SOLUTION: A test method and a test device are constituted so as to judge whether or not short-circuit failure is caused in an external terminal 102 on the basis of output signal levels of a first buffer circuit 4 having first input threshold value voltage and a second buffer circuit 6 having second input threshold value voltage different from the first input threshold value voltage by impressing high level and low level voltages on the external terminal 102 being a test circuit point through an output buffer circuit 104 in a switching system.  Thus, even if abnormality cannot be rightly detected due to a fluctuation in the input threshold value voltages in the output signal levels of the buffer circuits where a signal level of the external terminal 102 is a level close to the input threshold value voltage of one buffer circuit, the abnormality can be rightly detected by the output signal level of another one buffer circuit.

Title: Heat body detector
Inventor: MASUO YOSHIHISA
IPC: G01J5/16
Filed: 1988-11-08
Abstract: PURPOSE:To prevent erroneous detection by arranging an infrared rays detection means, a reference signal generation means, a comparison means and a reference signal control means. CONSTITUTION:An infrared rays detection means 1 contains a detector to generate an electrical signal according to an infrared energy radiated from within a specified area. A reference signal generation means 2 generates a reference signal to be compared with an output of the detection means 1. A comparison means 3 compares an output of the detection means 1 with the reference signal to judge whether a heat body exists within a specified area. A reference signal control means 4 changes the reference signal based on a maximum value of a temperature change presumable within the specified are after the detection of the heat body by the comparison means 3, which means that the reference signal is changed allowed for the largest presumable change on the assumption that a background temperature varies to approach the temperature of he heat body. Thus an output of the detection means 1 falls below a reference voltage so much that a detection output from the comparison means 3 is turned OFF when the heat body is removed under such a condition.
