Filed: 1989-04-27
Abstract: PURPOSE:To obtain a ZnO element having both a small thermal loss, when a current is constantly applied, and the excellent temperature characteristics of the thermal loss by a method wherein the cool-down speed when a non-linear resistor is sintered is limited within the specially prescribed range. CONSTITUTION:The cool-down speed when a non-linear resistor is sintered is set at 10 deg.C/hr. to 50 deg.C/hr. For example, Bi2O3, Co2O3, Sb2O3, MnO2, Cu2O3, SiO2 and NiO or 0.25 to 2mol% for each of them are added to ZnO as an additive component, the slurry obtained by wet-mixing using PVA as a binder is dried up by a spray driver, and granulated powder is obtained. This granulated powder is molded into a disc or 80phiX30t, and after it has been calcined at the temperature of 850 to 1000 deg.C, an inorganic insulative slurry is applied on its side face, it is sintered at a temperature between 1100 to 1259 deg.C, and cooled at the cool-down speed to 600 deg.C when sintering is set at 10 deg.C/hr. to 50 deg.C/hr. As a result, an element having a small loss component can be obtained by uniformizing the composition of the element of the non-linear resistor and also by suppressing the evaporation of the component molecule from the surface of the element.

Title: Video signal reproducing device
Inventor: YAMANISHI KAZUYOSHI
IPC: H04N9/83
Filed: 1985-05-21
Abstract: PURPOSE:To reproduce properly a chromaticity signal and to insure a luminous high frequency component against fluctuating due to a jitter by bisecting a signal subjected to low frequency conversion and giving no jitter to the chromaticity signal and making the high frequency component of a luminance signal into a signal having the same jitter as a low frequency component. CONSTITUTION:In terms of a APC 902, a jitter component is removed by the 1st fixed oscillator 95, and is frequency-converted. A chromaticity comb line filter CCF 7 outputs only the chromaticity signal. In terms of an APC 901, the signal is frequency-converted as it has a jitter with the aid of the output of an FM demodulator 55. A high frequency luminance signal YH obtained in such a way, carrier chromaticity signal and a low frequency luminance signal YL being the output of the FM demodulator 55 are synthesized. Thus an output terminal 76 obtains the carrier chrominance signal without a jitter and the luminance signal having the same jitter in the low and high frequency components. Since the chromaticity signal has no jitter, its color is properly reproduced, and the high frequency component of the luminance signal can be viewed without fluctuation.

Title: Character recognizing method
Inventor: OKUHARA TORAYUKI
IPC: G06K9/00
Filed: 1983-06-17
Abstract: PURPOSE:To improve the rate of character recognition by recognizing a character by correlating the read character to a character that corresponds to the width of the letter. CONSTITUTION:A microprocessing unit MPU11 sends a card in the lateral direction at a constant speed when it senses a card detection signal by a sensor 16. A magnetic head for reading 18 acans the card relatively and reads magnetic ink. The reading signal from the head 18 passes through an amplifier 19 and an LPF20 and converted to a digital signal by an A/D converter 21 and stored once in an RAM22. Then, the MPU11 detects a starting point of the character from read data stored in the RAM22, and at the same time, detects end point of the letter referring to the starting point, and detects the width of the character. The MPU11 compares the width with stored reference code, and when they coincide, stores it in the RAM22. Thus, by recognizing a character to be read by correlating it only with a character corresponding to the width of the character, erroneous reading can be reduced.

Title: Manufacture of permanent magnet
Inventor: AOYAMA AKIRA
IPC: C22C1/04
Filed: 1980-08-08
Abstract: PURPOSE:To increase magnetic characteristics and to prevent damage to a mold by a method wherein vacuum suction is applied to the air at the space of each rare earth Co powder and between the powder and a molder and pressure mold is done in the magnetic field. CONSTITUTION:In a conventional method, the air is confined in the spaces among powders and when a dust substance 7 is taken out from a mold 3 by excluding pressure after pressure mold, the compressed air in the spaces of powders expands and applys pressure to the inside of the mold to damage the mold 8 to deteriorate the dimensional precision of the product. If a device applying press mold to magnetic powder in the magnetic field is accomodated in a vacuum tank 3 for vacuum suction 10 and mold is conducted in the magnetic field as usual, the occupancy rate of the air remarkably decreases. Therefore, magnetic characteristics will rapidly be improved and a relatively big sample can easily be obtained.

Title: Driver of permanent magnet motor for electric car
Inventor: OZAKI SATORU
IPC: H02P23/00
Filed: 1999-04-16
Abstract: PROBLEM TO BE SOLVED: To easily provide a measure for over-voltage due to non-load induction voltage of a motor and restart of inverter, by inserting in series a parallel connecting circuit of a one-way conducive means and a switching means between the power supply of inverter and inventor arm. SOLUTION: For example, in the case of restarting inverter operation during rotation of a PM motor 5, the inverter operation is restarted while a switching means 7 is kept open with a control device 40. In this case, while a torque current element is maintained at zero, only the energizing current element is controlled to set a terminal voltage of the PM motor to the predetermined value. As a result, a magnetic flux of the PM motor 5 is lowered, thereby lowering an inducted voltage. Charges accumulated in the capacitors 31 to 33 are lowered due to the switching loss of the inverter operation during this period and consumption by copper loss of a coil of the PM motor 5. In this case, when loss exceeds an extra element of the charging voltage of the capacitors 31 to 33 for the power supply voltage, the power is supplied from the power supply side 1 via the one-way conductor means 8.
