Title: Stabilizer for discharge lamp
Inventor: SHIRATO JUNJI
IPC: H01F27/40
Filed: 1988-09-27
Abstract: PURPOSE:To reduce a common line after having an overcurrent protective function by interposing current fuses on both ends of a choke coil to be connected in series to power supply and a discharge lamp. CONSTITUTION:A stabilizer 12 for a discharge lamp has a choke coil 14 and a current fuse 15 is interposed between one end of this choke coil 14 and aforesaid power supply 11, while a current fuse 16 is interposed between the other end of the choke coil 14 and one end of a discharge lamp 13, further on the power supply side, a capacitor 17 and resistor 18 for power factor improvement are connected in parallel to power supply 11. For instance, when an overcurrent flows to a circuit due to a ground fault or the like of the choke coil 14, the current fuse 15 or the current fuse 16 on both ends of the choke coil 14 are melted so that burning of the stabilizer is prevented while checking occurrence of a fire or the like. Further, by interposing the current fuses 15 and 16 on both ends of the choke coil 14, the choke coil 14 can be protected against the overcurrent even when the choke coil 14 and the discharge lamp 13 are connected in series to power supply 11.

Filed: 1985-10-29
Abstract: PURPOSE:To prevent a recycle sequence from being entered and to improve the performance of data processing by inhibiting other requests from being accepted until the 1st move-in request is generated after a by-pass request is generated. CONSTITUTION:Information from a storage control unit MCU is inputted to an MCU interface control circuit 11, which outputs the by-pass request, the move-in request, and a priority selection inhibit signal.

Title: Vacuum circuit breaker
Inventor: FUJII FUMIHIKO
IPC: H01H33/66
Filed: 1998-08-27
Abstract: PROBLEM TO BE SOLVED: To decide whether or not different power supplies can be connected instantaneously and surely by deciding the phase of the different power supplies joined with a primary-side connecting section and a secondary-side connecting section respectively, and controlling a display state on the basis of the result of the decision. SOLUTION: Voltage signals detected by voltage detectors 6a, 6b respectively are transmitted to a comparison operation instrument. When the phase of different power supplies connected to a primary-side connecting section 5a and a secondary-side connecting section 5b for a main circuit respectively is equalized or the power supplies are not conjoined, an LED 2 for displaying charge is brought to a put-out state in the comparison operation instrument. When the phase of the power supplies differs or when only either one of the primary-side connecting section 5a or the secondary-side connecting section 5b is charged, on the other hand, the LED 2 for displaying charge is lit. Accordingly, whether or not connection is enabled can be judged instantaneously only by confirming the putting-out of the LED 2 for displaying charge for the front panel 1 of the vacuum circuit breaker.

Title: Measuring method of internal defect of semiconductor wafer, and controlling method of thermal oxidation furnace using the same
Inventor: MAEDA SATOSHI
IPC: G01N21/88
Filed: 1994-09-09
Abstract: PURPOSE: To obtain a method enabling stable and accurate measurement of lifetime of the whole surface of a wafer in a manner of non-destruction, noncontact and non-contamination and a method enabling determination of the degree of contamination and others of a thermal oxidation furnace. CONSTITUTION: An oxide film is formed on the surface of a silicon wafer washed by an SCl solution and a negative electric charge is given to the surface by casting an ultraviolet ray thereon. An Al compound is made to exist in this film and thereby the negative electric charge is held for a long time. By applying heat treatment at a temperature of 50 to 200 deg.C, adsorbed water on the film is desorbed and a charge holding force is enhanced. A laser light is cast on the surface of the wafer so as to excite a carrier and a time required for the carrier to reach the concentration of 1/e of the peak concentration thereof from the state of this concentration is measured. After lifetime is measured without forming a thermal oxidation film on the surface of the wafer, the thermal oxidation film is fitted in a thermal oxidation furnace and measurement of the lifetime is executed.  The degree of contamination and others of the thermal oxidation furnace are determined on the basis of measured values obtained at two times. The larger the difference between the measured values is, the larger the degree of contamination is.

Title: Steering control device of fork lift truck
Inventor: UTSUNOMIYA MASAAKI
IPC: B62D113/00
Filed: 1999-08-30
Abstract: PROBLEM TO BE SOLVED: To make small the approach speed to a steering wheel operating angle of a steering angle by setting a current command value to be small when the steering wheel operating angle and a steering angle are approached to each other, in an output characteristic curve. SOLUTION: When a steering angle and a steering wheel operating angle are approached to each other based on output characteristic curve, the gradient value of a straight line C1 is set to be mx smaller than the ordinary gradient value m according to the size of the temporal rate of change of deviation E. Hereby, the deviation E becomes small, and a current command value V exceeding Rx becomes a value indicated by a straight line Cx having a small gradient value mx. Consequently, because an approach speed becomes small form that at large deviation E, it becomes smaller than the speed at crossing, and the overshoot quantity from the steering wheel operating angle of a steering angle after crossing become also small. The time from first crossing to damping of vibration of the steering angle to stop can be also made small.

Title: Superconducting bulk body and superconducting bulk magnet
Inventor: KAMIJIYOU HIROTAKA
IPC: H01F6/00
Filed: 1997-09-08
Abstract: PROBLEM TO BE SOLVED: To prevent breakage of a superconducting bulk body when the bulk body is magnetized by only magnetizing the outer peripheral side of the bulk body in a ring-like state. SOLUTION: When a magnetic field of such a magnitude that magnetic fluxes only intrude into a magnetized area 3 on the outer peripheral side of a superconducting bulk body 1 is impressed upon the bulk body 1 by appropriately adjusting a pulse current after a coil 7 for magnetization is wound around the bulk body 1, only the outer peripheral side of the bulk body 1 is magnetized in a ring-like state, because the magnetized area 3 of the bulk body 1 is magnetized by the magnetic fluxes intruding into the area 3, but no magnetic flux intrude into the nonmagnetized area 5 of the bulk body 1 and the area 5 is not magnetized.  Only the outer peripheral side of the bulk body 1 can also be magnetized in the ring-like state even when the magnetic field is impressed upon the bulk body 1 while the magnetized area 3 is maintained in a superconducting state and the nonmagnetized area 5 is maintained in a normal conducting state. The same effect can be obtained when the inside of a hollow cylindrical superconducting bulk body is filled with a reinforcing member of a resin, etc.
