Title: Manufacture of varistor
Inventor: TAIRA HIROAKI
IPC: H01C7/10
Filed: 1988-11-16
Abstract: PURPOSE:To improve surge strength and to abbreviate complex enclosing work while securing prescribed varistor voltage and a non-linear coefficient by performing hot isostatic press(HIP) treatment on a presintered body of a raw material for a varistor in a specific high-pressure gas atmosphere. CONSTITUTION:A presintered body that is a compact of ceramics powder sintered at a prescribed temperature is given HIP treatment in high-pressure gas above the whole pressure 10 atmosphere and above oxygen partial pressure 0.05 atmosphere. Here, when the whole pressure is made under 10 atmosphere, an effect for improving density can not so much obtained so that surge strength can not be improved, while when oxygen partial pressure is made under 0.05 atmosphere, steal out of oxygen in the sintered body can not be prevented so that a varistor characteristic is greatly changed from initial value. Thereby, the varistor being excellent in all of varistor voltage, a non-linear coefficient and surge strength can be obtained while preventing oxygen emission of the sintered body during HIP treatment, so that a complex capsule enclosing process can be dispensed with so as to improve productivity.

Title: Information display device
Inventor: TAKASUGI KEIJI
IPC: H04B10/2507
Filed: 1998-10-12
Abstract: PROBLEM TO BE SOLVED: To prevent deformation of a signal waveform and unnecessary radiation at the time of transfer of a signal for information display. SOLUTION: On a road information board 21, an electric signal for showing the information to be image-displayed on a display part 23, is generated from a signal generation part 26 as a change of a direct current level. The electric signal is converted to a luminous signal with an intensity corresponding to the level of the electric signal by an electricity-light conversion part 30. The converted luminous signal is inputted into a light-electricity conversion part 22 of the LED(light emitting diode) display part 23 through a luminous signal transfer part 27 by an optical fiber cable, converted into an electric signal, and displayed as an image on the LED display part 23. The image display on the LED display part 23 is executed by an electric power supplied from a power source part 28 through a power transfer part 29, such as a power source cable or the like.  As the signal transfer is executed by the luminous signal, deformation of a signal waveform is prevented to thereby enable accurate signal transfer, and also unnecessary radiation can be prevented.

Filed: 1988-11-17
Abstract: PURPOSE:To optimumly control the packing hydraulic pressure in accordance with nuclear reactor pressure by providing a pressure regulating valve on a part between an outlet of a pump of a third piping and a branch point of a fourth piping. CONSTITUTION:When pressure of a nuclear reactor 1 is in an atmospheric pressure state, a pressure regulating valve 15 is reduced in accordance with a set value X, a pressure drop by the pressure regulating valve 15 is large, and pressure of a branch point 11, that is, packing pressure to an accumulator 5 is suppressed low. A flow regulating valve 13 is controlled automatically so that a flow rate becomes constant by a signal of a flow meter 12, therefore, a contraction of area is opened by a low portion of pressure of the branch point 11, and to a control rod driving mechanism 2, constant cooling water is supplied through a cooling water line 10. When the reactor pressure rises, the pressure regulating valve 15 is opened in accordance with the set value X, the pressure drop by the pressure regulating valve 15 decreases, and the pressure of the branch point 11, that is, the packing pressure to the accumulator 5 rises. In such a way, the pressure drop of the pressure regulating valve is controlled so as to become a set value corresponding to a variation of the reactor pressure, and optimum packing pressure is obtained.

IPC: F02D41/02
Filed: 1999-10-13
Abstract: PROBLEM TO BE SOLVED: To stabilize combustion in a cylinder operated in a rich air-fuel ratio and prevent plug smoldering when an air-fuel ratio control in each of cylinder groups is carried out for rising catalyst temperature. SOLUTION: When the air-fuel ratio control in each of cylinder groups is carried out for rising temperature of an NOx catalyst 8, An ECU 20 controls a main injection amount such that a lean air-fuel ratio is realized in a first cylinder group constituted of a first cylinder 1A and a fourth cylinder 1D, and a slight rich air-fuel ratio (about 12.5) is realized in a second cylinder group constituted of a second cylinder 1B and a third cylinder 1C. In the second cylinder 2B and the third cylinder 1C of the second cylinder group, the ECU 20 carries out sub injection of fuel in an expansion stroke and an exhaust stroke. Accordingly, an air-fuel ratio of an exhaust gas discharged from the second cylinder group is made to be a strongly rich air-fuel ratio (8 to 11) thereby ensuring an unburnt fuel component necessary for rising temperature of the NOx catalyst 8.

Title: Pattern address generating device
Inventor: ISHIZAKA MASAAKI
IPC: G01R31/28
Filed: 1991-11-07
Abstract: PURPOSE:To enable an IC tester to generate a pattern address at a high speed. CONSTITUTION:A sequencer 12 and microprogram memory 13 generate an initial address for generating continuous pattern addresses S2 and control instruction S3 for designating a repetitive number. An address counter 14 and repeat counter 15 generate a series of continuous pattern addresses S2 in accordance with the instruction S3. Namely, the address counter 14 increments the pattern addresses S2 at every rate clock pulse S1 and the repeat counter 15 counts the repetitive number by performing subtraction. When the repetitive number is reached, the counter 15 outputs a zero signal S5 and operates the sequencer 12 by sending the rate clock pulse S1 to the sequencer 12 as a sequencer clock S6 through an AND circuit 16. By operating the sequencer 12 at a low speed while the counters 14 and 15 operation at high speeds in such way, a pattern address can be generated at a high speed.
