Title: Amplifying circuit
Inventor: OGAWA ATSUSHI
IPC: H03F1/30
Filed: 1981-05-14
Abstract: PURPOSE: To cancel the voltage fluctuation between a base and an emitter and to enable low voltage operation, by supplying a current proportional to a thermal voltage of a transistor (TR) to a bias circuit in series connection of diodes.  
     CONSTITUTION: A constant current circuit 13 supplies a current IB proportional to a thermal voltage VT of an amplifying TRQ 10  to a bias circuit 12 consisting of two series diodes D 11  and D 12  and a resistor RB. The resistor RB is made equal to the sum of an emitter resistor RE and a collector RL. The operating current of the TRQ 10  is made equal to the current IB supplied from the constant current circuit. As a result, the forward voltage of a bias diode and a voltage between the base-to-emitter voltage of the TRQ 10  are cancelled. Thus, the amplification factor is not subjected to the effect of the temperature. Since only two diodes for the bias circuit are required, the circuit can be made low in the voltage.

IPC: C21D7/13
Filed: 1989-03-25
Abstract: PURPOSE:To easily manufacture a permanent magnetic having high performance at low cost by hot processing an ingot made by melting and casting an alloy containing R, Fe, B as basic components at a specific temperature, and further heat treating at a specific temperature. CONSTITUTION:An alloy containing R (one type of rare earth metals including Y), Fe, Be as basic components is melted in an induction heating furnace, cast, and this cast ingot is hot processed at 500 deg.C or higher.

Title: Optical rotation re-detection apparatus
Inventor: KATADA MITSUTAKA
IPC: G01B11/26
Filed: 1985-04-05
Abstract: PURPOSE:To enhance dissolving power without performing erroneous detection, by providing a light emitting element arranged to one end side of the measuring light path formed to the lateral space of a rotary shaft and a rotary disc rotating so as to cross the measuring light path in synchronous relation to the rotary shaft. CONSTITUTION:The light from a light emitting elements 3 passes a rotary disc 2 to reach a light receiving element 41. A part of the light passing through a transmission region in the emitted light reaches a first light receiving element 43 for detecting angle of rotation. By this method, the light reaching the element 43 generates the variation in intensity with the rotation of the disc 2. A second reference light receiving element 2 receives the light passed through the transparent part of the disc 2. Therefore, the output from the element 42 becomes constant regardless of the rotation of the disc 2. By adjusting the positions of the elements 3, 41 to take the photocurrent corresponding to the central value between the max. and min. outputs of the light receiving part for detecting angle of rotation and that generated from the element 42 so as to make both of them equal, an AC signal always centering around zero is obtained from a subtraction circuit. This AC signal has no output dependence by frequency and the detection of an angle is made possible.

Title: Pneumatic radial tire
Inventor: KONO YOSHIHIDE
IPC: B60C9/20
Filed: 1994-04-12
Abstract: PURPOSE:To increase a hydroplaining production speed by forming a reinforcing layer with first and second rubber coat layers and making the interlayer thickness larger at the end part than that at the center part so as to make water difficult to enter the inside of a ground contact surface. CONSTITUTION:A belt 18 as a first rubber layer is arranged at the crown part of a carcass and a belt reinforcing layer 20 as a second rubber coat layer is arranged on the radial outer side of a tire. Also the direction of the cord of the belt 18 is tilted by a specified angle relative to the circumferential direction of the tire, and the direction of the belt reinforcing layer 20 is substantially in parallel with the circumferential direction of the tire. Then the interval (h) between the cords 18A and 20A of both layers 18 and 20 is made larger than a tire equatorial plane CL on the outer side of the tire in lateral direction. Thus, in traveling on wet road surface, water in the direction of traveling is removed to both sides in lateral direction and the amount of water entering the inside of the ground contact surface is reduced so as to increase the hydroplaining producing speed.

Title: Dc-dc converter
Inventor: MATSUMAE HIROSHI
IPC: H02M3/28
Filed: 1989-03-25
Abstract: PURPOSE:To improve an efficiency upon a light load by a method wherein the capacity of a snubber capacitor in the snubber circuit of a DC-DC converter is changed so as to be small upon the light load and large upon a heavy load. CONSTITUTION:When a load current is small and a spike voltage has not arrived at a set value, a FET 9 is put OFF and the combined capacity of a snubber circuit, constituted between the FET 2 and a drain source, becomes a value, obtained by combining the equivalent capacity 2b between the drain sources of the FET 2 and the series combined capacity of a capacitor 7, a capacitor 8 and the equivalent capacity 9b between the drain sources of the FET 9 in parallel. On the other hand, when the load current is increased and the spike voltage has exceeded the set value, the FET 9 is put ON and the combined capacity of the snubber circuit becomes a value obtained by compounding the equivalent capacity 2b between the drain sources of the FET 2, the capacitor 7 and the capacitor 8 in parallel.

IPC: H01J29/02
Filed: 1986-03-31
Abstract: PURPOSE:To prevent mislanding of an electron beam with a simple mechanism while giving an autmatic temperature correction function by connecting the fitting part and the attaching part of a supporting spring by a color selection electrode through a bent part when the color selection electrode is expanded. CONSTITUTION:A supporting spring 5 is constituted by connecting the fitting part 8 to a stud pin 7 fixed to a panel 6 and the attaching part 9 to a color selection electrode 1 through a bent part 10 in which the color selection electrode 1 deviates to the panel side 6 in the direction of an electron beam 11. Since the bent part 10 deviates in this way, it can take an optional shape so far as there is no problem in shock-proofness. When using the supporting spring 5 and a cathode-ray tube is in operation, the color selection electrode 1 deviates to the side of the panel 6 along the course of the electron beam 11 to automatically correct its position even when the color selection electrode 1 is thermalexpanded due to the electron beam. Thereby, mislanding of the electron beam 11 can be prevented.

Title: Ignition device for internal combustion engine
Inventor: OGAWA TOMOYUKI
IPC: F02P5/155
Filed: 1986-03-31
Abstract: PURPOSE:To simplify a circuit structure by comparing the first integral voltage with the second and third integral voltage, generating a trigger signal, and obtaining spark advance angle and spark delay angle characteristics via a common trigger signal output circuit for spark advance angle and spark delay angle control. CONSTITUTION:The first integral voltage Vc1 and the maximum spark advance angle position is constant, but the first integral voltage Vc1 at the minimum spark advance angle position is gradually decreased as the rotating speed is increased. The second integral voltage Vc2 at the maximum spark advance angle position is increased as the rotating speed is increased. The third integral voltage Vc3 at the maximum spark advance angle and the minimum spark advance angle is decreased as the rotating speed is increased. Accordingly, the first integral voltage Vc1 is compared with the second and third integral voltage Vc2, Vc3 so that a trigger signal is generated when the voltage Vc1 becomes higher than both Vc2 and Vc3. Then, various ignition characteristics that the spark angle is advanced at low and medium-speed regions and delayed at a high-speed region can be obtained by properly setting the integration constant of each integrating circuit.

Abstract: PURPOSE: To prevent misstop of recording and reproducing unit and to obtain the control signal other than automatic stop signal, by using the signal alternately repeating two signals different in the frequency for a given number of times as the automatic stop signal.

In this control signal, two signals F 1 , F 2  different in frequency as shown in (a), are repetitively recorded for a given number of times and one signal, e.g., F 2  is recorded in two different duration times. Since the signal like this is not present in conventional audio and music information, the automatic stop signal as shown in (h) can be obtained without malfunction. Simultaneously, when the signal longer in the signal F 2  is used as digital information 1 and shorter one is as digital information O, the control signal having a plurality of functions other than the automatic stop signal, as shown in (i), can be obtained.
