Title: Nonlinear resistor
Inventor: SUZUKI HIRONORI
IPC: H01C7/10
Filed: 1997-02-27
Abstract: PROBLEM TO BE SOLVED: To improve the discharge resistance characteristic of a nonlinear resistor, by lowering the varistor voltage of the resistor by using zinc oxide as a main component and bismuth and titanium as sub-components and evenly enlarging the sizes of ZnO crystal grains. SOLUTION: The raw material of a nonlinear resistor is prepared by adding 0.1-5.0mol% Bi2 O3 and 0.1-5.0mol% TiO2 to a main component composed of ZnO and mixing the components with water and an organic binder, such as the dispersant, etc., in a mixer. Then, the mixture is sprayed and granulated to a prescribed particle size by means of a spray dryer, and the granulated particles are molded into a disc, etc., with pressure in a mold. In addition, a sintered body 1 is obtained by baking the molded body for two hours at 1,200 deg.C in the air after the molded body is once baked at 500 deg.C in the air. After high-resistance layers are formed on the side faces of the sintered body 1 by applying an insulator having a high resistance to the side faces and baking the insulator, the both end faces of the sintered body 1 are polished and electrodes 3 are formed on the end faces by spraying aluminum upon the end faces. When a nonlinear resistor is formed in this way, the resistor has an excellent discharge resistance characteristic, because the varistor voltage of the resistor becomes 20-150V/mm.

Title: Diesel engine
Inventor: ETOU YUKIHIRO
IPC: F01L1/14
Filed: 1980-04-05
Abstract: PURPOSE: To improve initial running characteristic and to exclude knocking phenomenon by providing a control device for valve lifting whereby said control device can decrease lifting amount of a suction or exhaust valve at the initial running time or light load time of the engine to lower than compression ratio.  
     CONSTITUTION: A suction or exhaust valve 1 is opened against the elastic force of valve spring 7 by the lifting power from a cam 2 rotating synchronously with the engine revolution through an oil tappet 3, push-rod 4, wobbling cam 5 and rocker arm 6 as a valve lift controller. The arm length of oil tappet 3 is adjusted with response to the oil pressure from an oil pressure regulator 30 which serves as a detector for checking engine running state, so that the lifting amount of valve 1 can be made less in the initial running time or light loaded time of the engine. In such a way, unpreferably state in initial running is improved by less compression ratio and increased cranking r.p.m. and further knocking is excluded by lowered step-up degree of expansion pressure.

Title: Metal vapor discharge lamp
Inventor: SASAKI HIROMOTO
IPC: H01J61/26
Filed: 1983-03-18
Abstract: PURPOSE:To improve the starting characteristic by the use of a radioactive material. CONSTITUTION:As the radioactive material, a ceramic member 6 including, for exmaple, 0.05 microcurie of promethium 147 dispersedly sealed therein is used. The radioactive material and a getter, e.g., 0.5mg of scandium metal 7, are arranged to be contained in the containing portion 8 provided at a portion of the illuminating tube envelope 1. The illuminating tube arranged in such a way is mounted in an outer tube which is evacuated or filled with nitrogen, inert gas, etc. and a lamp is thus completed. To light the lamp, voltage is applied through a ballast across the terminals 2a, 2b from the external leads 4a, 4b. At that time, the argon gas in the vicinity of the radioactive material is ionized by the initial electrons emitted by the radioactive material, and this small amount of ionized gas upon application of the pulse voltage causes electric breakdown in the illuminating tube and thus the lamp is started.

Title: Power synthesizing amplifier
Inventor: IKEDA AKIHIRO
IPC: H03F3/60
Filed: 1987-02-28
Abstract: PURPOSE:To ensure a high reliable output even when the characteristic of one amplifier is deteriorated by interposing a switch between power supplies of two sets of amplifiers applying power synthesization respectively and providing a control circuit applying switch control to the switch so as to interrupt either amplifier. CONSTITUTION:A switch 5 is interposed between an amplifier 1 and its power supply circuit 7, and a switch 6 is interposed between the amplifier 2 and its power supply circuit 8 similarly. If the amplifier 1 is faulty and its distortion characteristic is deteriorated, since a distorted signal is outputted at the output of an output synthesizing hybrid 4, a code error takes place in the multi-value PCM transmission system and the line quality of the PCM transmission is deteriorated. Thus, the production of code error is detected and in opening the switch 5 through a control circuit 9 externally, the operation of the amplifier 1 is stopped and the output from the output synthesizing hybrid 4 is decreased by 6dB, but since the output of the amplifier 1 is shut off completely, no distortion is outputted and only a signal with low distortion is outputted from the synthesizer 4 through the normal amplifier 2 to keep the quality of line.

Title: Cam
Inventor: SAGA NORIHIKO
IPC: C23C4/12
Filed: 1984-03-07
Abstract: PURPOSE:To improve the machinability of a cam portion by treating for remelting each portion of a cam portion in such a manner that the hardness of the rising portion of a cam is low, and the hardness of the top portion of the cam is high. CONSTITUTION:The hardness required for the rising portion on 5 and the top portion 8 of a cam is set according to the distribution of surface pressure of a cam to be excellent in congeniality with the other party, a locker arm, and improve wear-resisting property. As the hardness of a long contact arc rising portion 5 of the cam is lower than that of the top portion 8 of the cam, it is not necessary to decrease the angular velocity unlike the conventional cam. While the cam is turned in fixed rotation according to the short contact arc top portion of the cam, grinding operation can be performed so as to speed up the grinding machining.

Title: Ignition time correcting device for internal combustion engine
Inventor: KOMURASAKI SATORU
IPC: F02P5/155
Filed: 1980-04-03
Abstract: PURPOSE: To correct the deviation of the ignition time by detecting the deviation of the ignition time upon the referenced level operation of the engine, and correcting the ignition time so as to set it at the normal ignition time in correspondence to the detection memory output.  
     CONSTITUTION: A reference signal generator 2 generates a reference signal at a predetermined reference angular position, and an ignition signal generator 1 generates an igntion signal at an angular position advanced from the reference signal. A phase difference angle detection circuit 4 receives the reference signal and a delay ignition signal, and generates a leading angle correction signal having a pulse length corresponding to the phase difference angle between both signals. When it is detected by an idling detector 5 that the engine is in an idling state, the leading angle signal is supplied to a reversible driving device 7 through a gate circuit 6 to drive a reversible motor 71 and adjust a variable resistor 8. Accordingly, the phase of an ignition signal is corrected to a predetermined phase relationship with respect to the reference signal. In a driving state other than idling, the gate circuit 6 is closed and this correction is not carried out.

Title: Copy sheet storage case detecting system
Inventor: KODAMA YUTAKA
IPC: B65H7/04
Filed: 1981-03-26
Abstract: PURPOSE:To make it possible to detect the presence or absence of copy sheets in a copy sheet storage case and also detect whether its top cover is opened or closed by a single photoelectric switch in response to the movement of detecting elements by providing a bottom plate pressing copy sheets against a roller and the top cover of the case with fillers, each having a detecting element. CONSTITUTION:When a copy sheet P is present on a moving bottom plate 8 and a top cover 11 is correctly in the closed position, a shutter leaf 28 of a detecting plate 25 is positioned in the opposing gap 30 in a photoelectric switch 29 and therefore the switch 29 sends the controller a signal for continuing the copying operation. When there is no copy sheet on the bottom plate 8a, filler end 23 falls into an opening 24 and as a result the detecting plate 25 rotates counterclockwise and the shutter lead 28 moves downward from the gap 30. When the top cover 11 is not in the closed position, the detecting plate 25 is caused to rotate clockwise by the filler 31 and moving plate 37 and moves upward from the gap 30. In either case the photoelectric switch 29 sends out a signal indicating the impossibility of copying operations.

Title: Detecting system of interference wave
Inventor: KAGE GOUZOU
IPC: H04B17/00
Filed: 1982-03-23
Abstract: PURPOSE:To detect interference precisely by using a receiving signal from which level fluctuation due to fading is removed and also using level fluctuation at the time of no modulation. CONSTITUTION:A receiving signal (in) is applied to an amplifying circuit 1 whose gain is automatically controlled, so that level fluctuation due to fading is removed. The outpt of the amplifying circuit 1 is applied to an amplitude detecting circuit 2 and a beat waveform is extracted. The beat waveform is applied to a level measuring circuit 3, the measured result is compared with a reference value Vc by a comparator 4 and carrier level fluctuation due to an interference wave is detected and applied to a gate circuit 7. On the other hand, the output of the amplifying circuit 1 is modulated by PM (or FM) demodulator 5. The demodulated output is applied to a call detecting circuit 6 and whether the signal is modulated or not is detected. During calling, a call detection signal is applied to the gate circuit 7 to close the gate 7. Thus the level fluctuation due to fading or at calling is prevented from being wrongly detected as the level fluctuation due to an interference wave, so that a precise detection output (out) can be obtained.
