Patent JP-H0928085-A (JP)
Title: Inverter
Inventor: HIRATA TOSHIYUKI
IPC: H02M7/48
Filed: 1995-07-13
Abstract: PROBLEM TO BE SOLVED: To eliminate a rush current and avoid breakdown of a power transistor by a method wherein, if a switching device is going to be turned off before a resonance current reaches a predetermined value, that fact is detected and the output of an off-signal is delayed until the resonance current exceeds the predetermined value. SOLUTION: First and second power transistors 4 and 5 which are switching devices are alternately turned on and off to apply a high frequency current to an induction heating coil 12. A cooking pan U placed near the induction heating coil 12 is heated by the induction from a high frequency magnetic field generated by the applied high frequency current. In such a process, if the oscillation frequency of an inverter circuit 13 is elevated and the power transistors 4 and 5 are going to be turned off before a resonance current detected by a current transformer 16 reaches a predetermined value, that fact is detected by a window comparator circuit 25 and the output of an off-signal is delayed by a lowest frequency regulating circuit 26 until the resonance current exceeds the predetermined value and a highest frequency is regulated.

Filed: 1990-07-05
Abstract: PURPOSE:To obtain constant optical low-pass effect irrelevantly to wavelength by composing two compound prisms which have periodic structure linearly and specifying the refractive indexes of materials which form respective prisms. CONSTITUTION:Phase grating filters which have prism surfaces arrayed periodically and linearly are combined in the direction of the optical axis so that the prism surfaces contact each other, and cX0.98<n1(alpha)/n2(lambda)<cX1.02 n1(lambda): refractive index (object-side material), n2(lambda): refractive index (image-plane side material) holds in an in-use wavelength range when the refractive indexes of the adjacent surfaces of a phase diffraction filter are so determined that n1(lambdao/n2(lambdao) = C (c: certain constant) when wavelength is lambdao. Then how a light beam is reflected between compound prisms is determined so that the ratio of the refractive indexes of the prism forming materials corresponding to each wavelength is constant; and the separation width of luminous flux corresponding to each wavelength is made constant to obtain stable optical low-pass effect characteristics with each wavelength.

Title: Load controller for common buffer memory
Inventor: TAKAHATA YOSHIAKI
Filed: 1992-07-06
Abstract: PURPOSE:To accurately grasp the load state of a common buffer memory by providing a cell counter means and a maximum stored cell number storage means and controlling the load of the common buffer memory based on the information on the maximum stored cell number read out of the storage means. CONSTITUTION:When a monitoring cycle timing signal 107 is generated from a call monitoring control part 41, the maximum stored cell number information 105 obtained in a monitoring cycle is transferred to the part 41 from a maximum stored cell number storage part 35. At the same time, the maximum stored cell number that is so far stored in the part 35 is cleared. Then the intra-buffer memory cell number information 102 is received from a cell counting part 34 and the intra-buffer memory maximum stored cell number is stored before the signal 107 arrives. Thus the load change can be statistically and correctly reflected even if the load applied to a common buffer memory 32 is suddenly changed due to the burst cell flows inputted to the input highways 11-1n. Therefore the load of the memory 32 can be accurately controlled based on the information 105.

Title: Centering apparatus
Inventor: IKESHOJI SUSUMU
IPC: G21C13/02
Filed: 1988-07-18
Abstract: PURPOSE:To enable the implementing of accurate centering in a short time by a method wherein a starting point of oscillation is fixed with the abutting of a sensor, an oscillation is started at the point and the oscillation is stopped with the reabutting of the sensor after a specified time. CONSTITUTION:A nut tightening device 4 has at least a pair of centering deviation measuring sensors 6 which is so suspended above a stud bolt 1 and is mobile so as to abut a circumferential side of the stud bolt 1. Then, even while the device 4 oscillates finely, a starting point of oscillation is fixed with the abutting of a sensor contact 6A of the centering deviation measuring sensor 6 and oscillation is started at the starting point of the oscillation. After a specified time determined previously by a computation, the oscillation is stopped with the reabutting of the contact 6A. By so doing, as the position of the stoppage is as for the center of the oscillation, the oscillation can stop. This can eliminates a difficulty in a short time in centering due to a fine oscillation caused by free suspension of the device 4 on the stud bolt 1.

Title: Estimating method for factor of process fault
Inventor: HAGIWARA KENICHI
IPC: G05B23/02
Filed: 1993-07-20
Abstract: PURPOSE:To provide an estimating method which can estimate the factors of faults when the patterns different from the stored fault patterns occur in various process plants, etc., can estimate such an unstable state that needs much time for transmission of a fault, and also can decrease the fault patterns to be prepared to the minimum. CONSTITUTION:A fault pattern 101 shows the state of a subject process for each of its information items and receives the fault factors that may possibly occur in a relevant state. This pattern 101 is previously stored in a fault pattern storing part 102. When a process has a fault, the fault pattern equivalent to the pattern 103 of the occurred fault is retrieved by a fault factor estimating part 104. If the relevant fault pattern is not retrieved, the fault patterns stored in the part 102 are inverted and synthesized. So that a new fault pattern 106 is generated at a fault pattern generating part 105 and stored in the part 102. The stored pattern 106 is used for the subsequent estimation of fault factors.

Title: Colored orthopedic resin and gypsum material composed thereof
Inventor: CHIYAARUZU KURISUTOFUAA PORUTA
IPC: A61L15/07
Filed: 1990-07-06
Abstract: PURPOSE: To provide a colored resin for orthopedics and a plaster by using a chromophore-containing polyol or reactive coloring agent available to be mixed into a prepolymer reactive mixture. CONSTITUTION: This colored resin for orthopedics including hydraulic and isocyanate-functional polyurethane prepolymer, is formed by reacting the prepolymer with polyol and excessive polyisocyanate. At least a part of polyol contains a chromophore to be covalently bonded to the prepolymer. The chromophore contained in the polyol gives a desired color to the resin for orthopedics. A preferable resin, for instance, contains polyol containing the chromophore, in addition to the reaction material of a mixture of oxidized polypropylene polyol and isocyanate. For extending the storage life of the resin, it is preferred to contain benzoyl chloride and a stabilizer. The reactivity of a resin available to be hardened after it is exposed to moisture, can be controlled by a catalyst.  The reactivity must be high enough to form a hard film quickly over the resin surface to prevent any more moisture from entering into the bulk of resin, and to harden it before completing the application and formation of a plaster and supplementary orthopedic products.

Title: Multicusp type microwave ion source
Inventor: INAI YUTAKA
IPC: H01J37/08
Filed: 1994-07-06
Abstract: PURPOSE:To prevent an electron from losing energy by colliding with an inner wall by arranging metallic bias plates electrically insulated from a chamber inner wall so as to cover the inner wall except the cusp tip, and imposing a negative bias on them. CONSTITUTION:Lines 3 of magnetic force are generated by permanent magnets 2 on the outer periphery of a chamber 1, and a cusp magnetic field is formed. Circular arc-shaped bias plates 20 arranged between an inner wall of the chamber 1 and the cusp magnetic field so as to copy after a cusp shape are composed of a thin heat resistant metallic plate, and are supported on the inner wall with insulators. A negative bias is imposed on to the plates 20 by bias electric power supply 21, and they are put in negative electric potential to a wall surface. Plasma generated when a raw material gas is excited by a microwave is shut up in a central part by magnetic fields of the magnets 2 and electric fields of the plates 20. In this case, though electrons captured by the lines 3 of magnetic force are moved to the center along a spiral 23, a partial electron 26 passing through a magnetic field 27 is repulsed by the rear plates 20. Therefore, the electron shutting-up time becomes long, and collision with the wall is reduced.
