Title: Manufacturing method of induction heating clad material
Inventor: ISHIO MASAAKI
IPC: B23K101/12
Filed: 1999-04-30
Abstract: PROBLEM TO BE SOLVED: To provide a manufacturing method of an induction heating clad material with excellent temperature controllability, which can effectively utilize magnetic characteristics, which a temperature sensing magnetic material originally has. SOLUTION: In this method, a temperature sensing magnetic material, whose permeability varies according to temperature, and a good heat conducting metallic material are pressure-welded, and then are heated at the temperature which is higher than recrystal temperature of the temperature sensing magnetic material but lower than the melting point of the good heat conducting metallic material, so as to apply magnetic annealing for removing processing distortion existing in the temperature sensing magnetic material.  By the magnetic annealing, processing distortion introduced to the temperature sensing magnetic material at the time of pressure welding is eliminated, and temperature variation ratio dμ/dT of relative permeability can be made to be 10 or more where maximum value of the permeability before/after the curie point is 100 and minimum value is 1, so as to manufacture a clad material having excellent temperature controllability easily. Fe-Ni-Cr alloy or the like having the curie point of 40-600 deg.C is preferable for the temperature sensing magnetic material, and the metal mainly composed of Cu is preferable for the good heat conducting metallic material.

Title: Method for transmitting power transmission-distribution line information
Inventor: NAKAMIZO KOJI
IPC: H04B3/54
Filed: 1987-05-21
Abstract: PURPOSE:To lower a used carrier frequency, and to reduce a radio wave radiation from a power transmission distribution line, and at the same time, to reduce the cost of an equipment since a coupling capacitor is eliminated and voltage resistance is not necessitated as well by supplying a signal current in a non-resonant state to a coupling line installed separately from the power transmission distribution line and in parallel with it. CONSTITUTION:A signal line 4 allows the signal current I1 to flow through a closed circuit consisting of an overhead each wire 1 - a steel tower 2A - the earth 5 - the steel tower 2. Since a power transmission line 3 is installed in parallel with the overhead earth wire 1, an electromagnetic coupling is generated between both, and a signal voltage V2 and a transmission current I2 are induced on the power transmission line 3 by the signal current I1 and they are propagated along the power transmission line 3. At a receiving point, an induced current induced inversely on the overhead earth wire 1 by the transmission current I2 on the power transmission line 3, is detected by the current transformer 11 and is regenerated by a receiver 12. Thus, since the frequency of an electric signal propagating on the power transmission distribution line can be extremely lowered and the radio wave radiation can be reduced and at the same time, the coupling capacitor can be omitted, and the voltage resistance is not necessitated as well, the cost can be reduced, and a constitution and a maintenance can be simplified.

On the apparatus 35, intensity projection in each angle covering 0 deg.-18 deg. is obtained allowing these fringe images to rotate and the angle at the time when, out of the angles, an intensity projection provided with a characteristic different from that of other angle is detected is obtained as an angle of fringe. Next, the fringe image is rotated by the angle of fringe for arithmetic operation of the intensity projection and a decrement is calculated from the result and a frequency analysis is performed using the maximum entropy method for detection of the peak frequency and the fringe distances are obtained from the result by conversion.

IPC: H03K5/13
Filed: 1991-04-26
Abstract: PURPOSE:To realize the delay circuit immune to the effect due to temperature or voltage fluctuation by decreasing number of high impedance logic circuit elements in use. CONSTITUTION:An output of an inverting gate 2 and an output of a buffer circuit 10 are connected via a CMOS transmission gate 5.

IPC: G11B15/40
Filed: 1987-05-22
Abstract: PURPOSE:To prevent the generation of the twist and elongation of a thin tape by transferring a tape by touching to the tape with a face contact on the whole by the surface wave of a vibration body. CONSTITUTION:Tape transfer parts 1, 2, i.e., tape driving device is composed by arranging a set of piezoelectric elements 11, 12 on which the alternate voltage of different phase is impressed by alternate power sources Ea, Eb on a supporting body 10 by adjoining each other a lot.
