Title: Deformation correcting method of three-dimensionally shaped object
Inventor: WATANABE SHINOBU
IPC: G01B21/20
Filed: 1979-04-23
Abstract: PURPOSE: To measure and correct the deformation of a three-dimensionally shaped object mechanically and efficiently by comparing the coordinate values of the section measurement values of  arbitrary positions of the three-dimensionally shaped object and its model and controlling the resulted deformation amounts.  
     CONSTITUTION: In order to correct the torsional deformation amount of a work 1, a reference  part 3 is clamped to a reference plane 22, after which the correcting sectional position is clamped  G. Next, in this state, the torsional correction of the arbitrary section being clamped G is accomplished by rotating the plane 22. Next, in this state, torque is appied to the work 1 and is increased within the range that the deformation amount of the work 1 at the removing of the torque  after it has exceeded the elastic limit of the work 1 does not exceed the torsional deformation  amount θH. Next, the maximum torque T 2  and maximum deflection amount θ 2  of this time are  detected respectively, after which the torque is removed and the permanent deflection amount θ 1   of the work 1 is detected. The proportional constant K of the work 1 is obtained from the formula  I. Next, according to this constant K, the work is reloaded and the load removing point P which  satisfies formula II. is detected and the load is immediately removed. Namely, the torque T and  deflection amount θ are decreased by maintaining the inclination of the constant K from the point  P and the point when the torque T becomes zero is made qual to the torsional deflection amount  θH of the work 1 and this ends the correction.

SOLUTION: When an insulated gate bipolar transistor (herein after called IGBT) is supplied with a current in the arrow direction 10, a magnetic field is generated in the perpendicular direction to the running current, furthermore when a coil 9 is arranged in the direction traversing this magnetic field, this coil 9 generates a voltage V corresponding to the magnetic flux change of rate dΦ/dt. That is, the V satisfies the following formula of V=-μ0 NS/2πr.dI/dt in proportion to the coil turn number N, the area S and the current rise rate dI/dt. In the above formula, μ0 represents the magnetic permeability in vacuum of 4μ×10<7> (H/m).  In such a constitution, the current of semiconductor element can be constantly detected by detecting the voltage generated on both ends of the coil when the IGBT is supplied with any abrupt current such as abnormal current, etc., neither adding a resistance nor increasing any loss at all.

Title: Laser stimulation type atomic beam oscillator
Inventor: KUDOME KENJI
IPC: H03L7/26
Filed: 1987-03-04
Abstract: PURPOSE:To improve the frequency stability by detecting the luminous quantity of 2nd and 3rd laser beams absorbed in an atomic beam by a photodetector, and controlling the frequency of a microwave so as to maximize the luminous quantity based on the output of the photodetector, thereby improving the S/N in the resonance detection. CONSTITUTION:The 2nd laser beam having a frequency nu2 outputted from a stimulation laser 2b and a 3rd laser beam having a frequency nu3 outputted from a resonance detection laser 2c are radiated onto an atomic beam passing through a cavity resonator 3 to apply stimulation and the natural radiation light generated from the stimulated atom is detected by a photodetector 4. The microwave frequency is controlled so as to maximize the detected luminous quantity, that is, to maximize the absorbing quantity of laser beam. In such a case, energy of the atoms stimulated by the laser beam of the two frequencies are being saturated while a large quantity of radiated light is produced. As a result, the detected luminous quantity is increased, the effect of fluctuation of the laser beam is reduced and the S/N of the resonance detection is improved.

Abstract: PROBLEM TO BE SOLVED: To provide a radio channel assignment method in which a call loss is reduced and the frequency of channel switching is reduced in mobile communication.

Title: Color image forming method
Inventor: HANEDA SATORU
IPC: G03G15/01
Filed: 1992-03-06
Abstract: PURPOSE:To obtain the color image of excellent glossiness, high quality, and excellent preservabe property by setting the softening point of color toner lower than that of resin comprising a thermoplastic transparent resin particle. CONSTITUTION:After a color toner image 2A is formed on a photosensitive body, a resin grain layer is formed in an electrophotographic method, to form a transparent grain layer on the formed image. When the resin grain layer is heated/fixed by belt-like members 8a and 8b, the resin grain layer is melted and an uniform transparent resin layer 2B is formed. When the softening point of the color toner is set lower than that of a resin grain, the color toner is melted faster than the resin grain, and the toner of each color is sufficiently melted and mixed each other, to obtain an excellent color tone. Further, the color toner and the transparent resin layer, have different cross-linking structure and kind of resin, so that they are not melted/mixed, and reduction in reproducibility caused by the spreading of an image in a fixing stage, does not occur. Thus, a high quality color image which is not rugged but smooth, can be formed.
