Title: Measuring method of progress state of cross-linking reaction of rubber by electrical characteristic value
Inventor: OOKAWA YOSHINAO
IPC: G01N27/02
Filed: 1995-04-13
Abstract: PURPOSE: To obtain a measuring method in which the cross-linking progress state of an uncross-linked rubber can be measured by a method wherein one pair of specific steels plates out of a plurality of internal steel plates which support uncross-linked laminated rubber are used as electrodes, a cycle voltage is applied and an electrical characteristic value is detected. CONSTITUTION: Sheetlike unvulcanized rubber and steel plates 14 to 18 are arranged alternately inside a mold 20 which has been preheated to the vulcanizing temperature of the rubbers, and an axial-direction load is applied to the sheetlike unvulcanized rubber and the steel plates 14 to 18 by an upper plate 41 and a push plate 43 by means of a press machine 50. The laminated rubber 13 which are arranged in the mold 20 raise their temperature with the passage of time so as to reach the vulcanizing temperature, of the rubber, which is the same temperature as the mold. Thereby, as the cross-linking reaction of the laminated rubbers 13 progresses, an electrical AC resistance value is raised once, it is then lowered, and it then displays a constant value.  This indicates a point of time in which the time change rate of an AC resistance becomes nearly zero, and it is a point of time in which the cross- linking reaction of the laminated rubber 13 has been completed. Consequently, when a change in the time change rate of the electrical AC resistance is traced, the progress degree of the cross-linking reaction of the rubber can be observed.

Title: Spur plug with built-in resistance
Inventor: TANAKA MINORU
IPC: H01T13/20
Filed: 1988-05-11
Abstract: PURPOSE:To enhance the noise preventive effect by forming a resistance element from a film resistance element having a specified thickness and specified effective length on the surface of an insulative columnar base body, and by sealing the surrounding of connections of the film resistance element with a central electrode axis using a conductive sealing material. CONSTITUTION:Seal between a ceramic insulation 1 and a film resistance 4A and a seal 3 at the foremost part of a terminal electrode shaft 6 shall be a plug performed by insulating glass 8. This film resistance 4A shall be a resistance with an effective length over 10mm formed by providing a 1-1000mum thick tin oxide film or carbon film over the surface of an insulative columnar base body. A film resistance 4A in this constitution gives a stable resistance value and can be produced at a low cost. The reason for restricting the film thickness to 1-1000mum is because a greater film thickness lessens the resistance value to cause deterioration of the temp. characteristic of resistance value and reduction of the noise preventive effect, which further results in degradation of durability in spark ignition. This accomplishes good resistance thermo- characteristic and enhanced noise preventing effect.

Title: Optical transmitter of analog signal

IPC: H04B10/25
Filed: 1982-06-29
Abstract: PURPOSE:To transmit stably a signal with high quality at long range transmission, by applying amplitude modulation to an input signal and applying the result to a laser diode (LD) biased near a threshold current level so as to return the reflecting light from a connector during non-irradiating period of the LD. CONSTITUTION:An output of a high frequency oscillator 3 with variable oscillating frequency is used as a carrier of an amplitude modulator 2. An output current of a bias current generating circuit 4 is selected to a value close to the threshold current level of the laser diode (LD) 6. An irradiated light from the LD6 is coupled and supplied to a fiber 9 for transmission with a pig tail fiber 7 and a connector 8. Let the length of the pig tail fiber 7 be L, the frequency of carrier be fc, the period be tauc, and the refractive index of the fiber be (n), then the time difference tau1 between the irradiated light of the LD and the reflecting light from the connector 8 is tau1=2nL/C-m.tauc (where; C is the velocity of light and m is an integral number), since the reflecting light is returned during the non-illuminating period of the LD at tau1=tauc/2, the longitudinal mode of the LD is not almost subject to the effect of the reflecting light. Since the L is not always constant, the frequency of the carrier is adjusted to obtain tau1=tauc/2.

IPC: H02P6/20
Filed: 1979-09-05
Abstract: PURPOSE:To provide the DC semiconductor motor which has good mass production properties and in which the turn-on time of driving transistors can be made uniform, by generating driving pulses through an electronic control circuit instead of using a comparator and a variable resistor for regulating the threshold voltage of the comparator. CONSTITUTION:In starting, the O-level of the starting pulse output terminal of a CPU70 is applied to an AND gate G3 through an inverter I6. The power-synchronized pulse of a pulse generator 74 sent out from the gate G3 is applied to ternary counters 75, 76 through an OR gate G4. Driving pulses are sent to output terminals Q1'-Q6' from the ternary counters 75, 76 which perform counting by the input pulses. After a prescribed time, the CPU70 changes a starting pulse output into ''1'' to turn on an AND gate G2 and driving reference pulses transmitted through the gate G4 are applied to the ternary counters 75, 76 and a motor goes into a stationary state. The generation of the driving reference pulses is based on the O- output period of a Hall IC which is measured at every rotation of a rotor.

Filed: 1982-07-02
Abstract: A valve whose casing has two coaxial passages and a chamber disposed between the passages and receiving a valving element movable between an open position in which the passages are free to communicate with one another and a closed position in which the passages are fully sealed from each other. The housing is separably connected with a casing for a tubular filter through which the fluid entering via one of the passages flows on its way toward the other passage when the valving element is held in the open position. The casing can be detached from the housing only when the valving element is held in the closed position to thus prevent leakage or spillage of fluid from the housing on detachment of the casing. The valving element can include a rotary body or a membrane and a displacing member which latter is reciprocable in the chamber to move the membrane against an annular seat of the housing.
