Patent JP-H04119544-A (JP)
Title: Magnetic bias device
Inventor: KURODA MOTOKI
IPC: G11B5/02
Filed: 1990-09-10
Abstract: PURPOSE:To miniaturize the device by providing a magnetic substance at the center of a coil to apply rotational force to a permanent magnet. CONSTITUTION:When a turning or holding voltage is applied from a coil driving circuit to a coil 4, a magnetic substance 6a held at the center of the coil 4 is magnetized and contributed to the rotational force of a permanent magnet 3 by a magnetic field made by a current flowing in the coil 4. Therefore, without changing the size of the magnetic bias device, the rotational force to be applied to the permanent magnet 3 can be increased, and the device can be made extremely stable to the interference of an external magnetic field such as a magnetic circuit for driving an objective lens to the permanent magnet 3 so as to execute a stable recording or erasing operation at high speed. On the other hand, energy consumption can be reduced in the state of holding the permanent magnet 3, and stable recording or erasing resistant to disturbance such as oscillation or the like to the device in the holding state is enabled. Thus, an optical head for increasing the rotational force and the magnetic bias device can be made much closer, and the device can be miniaturized as well.

Filed: 1990-09-10
Abstract: PURPOSE:To show a satisfactory characteristic by bonding metallic magnetic thin films having total film thickness <=20mum formed on a non-magnetic base plate while facing the metallic magnetic film surfaces each other, and forming track width >=20mum. CONSTITUTION:Metallic magnetic films 2 and 2' having the total film thickness <=20mum formed on non-magnetic base plates 1 and 1' while facing the metallic magnetic film surfaces each other so as to constitute the magnetic head having the track width >=20mum. As the bonding method, a crystallized glass film is formed on the metallic magnetic film surface by a sputtering method or the like, and the metallic magnetic film surfaces are faced, heated and bonded by this crystallized glass. Thus, the magnetic head shows the satisfactory characteristic while eliminating characteristic degradation caused by the wide track width in comparison with the conventional magnetic head, and this effect is evident in the head which track width exceeds 20mum.

Title: Driving circuit for igbt gate
Inventor: ISHIBASHI HIDEAKI
IPC: H03K17/08
Filed: 1986-10-13
Abstract: PURPOSE:To attain the operation of an IGBT (Insulated Gate Bipolar Mode Transistor) within its safe operating region by providing a voltage reduction circuit decreasing its gate voltage to a prescribed limit value if a prescribed value or over of voltage is applied between the collector and emitter when the IGBT is turned on. CONSTITUTION:Resistors 22b, 22c are connected between the collector and emitter of the IGBT 3 and a base of a transistor (TR) 23 is connected to a connecting point P of the resistors 22b, 22c and since the potential of the connecting point P is low when the IGBT 3 is turned on, the TR 23 is not conductive. On the other hand, if short-circuiting the like takes place and a prescribed value of the voltage or over is applied between the collector-emitter of the IGBT, since the potential at the point P rises, the TR 23 is conductive. Thus, a Zener diode 24 is inserted between the gate and emitter of the IGBT 3 via the TR 23 and the gate-emitter voltage (gate voltage) is limited to a prescribed level decided by the Zener voltage.

Filed: 1993-09-28
Abstract: PURPOSE:To correctly select a fault zone when a simple fault occurs by obtaining the difference or the like of the voltage at the branch point of a multi-terminal single-circuit power transmission line. CONSTITUTION:The voltage Vb2,1 at the branch point b2 at either terminal of an (n)-terminal single-circuit power transmission line is calculated from a terminal T1. The voltage Vb2,2 at the branch point b2 is calculated from a terminal T2, and the difference DELTA1,2 between the voltage Vb2,1 and the voltage Vb2,2 is obtained. The voltage Vbn-1,n-1 at the branch point bn-1 is calculated from a terminal Tn, and the difference DELTAn-1 with the voltage Vbn-1,n-1 is obtained. If difference DELTA1,2 difference DELTAn-1, it is judged that no fault exists in zones bn-T1, b2-T2. The (n)-terminal single-circuit power transmission line is converted into an (n-1)-terminal single-circuit system. These procedures are repeated to finally convert it into a three-terminal single-circuit containing a fault zone, and a two-terminal single-circuit containing a fault zone is obtained.

Abstract: PURPOSE:To quickly detect an overflow without necessitating the trouble of adding an additional circuit for detecting the overflow by providing an inexpensive weighting resistor having prescribed accuracy and a switching circuit for detecting the overflow. CONSTITUTION:In a final stage after a sequential comparison A-D converting operation is executed N-times, a reference signal generator 3 sets only a switching circuit S0 to a conducting state and applies a reference signal V to a weighting resistor R0, by which the resistor R0 outputs a reference signal V/2<n>, and also, switching circuits T connected to digital signals D1-DN of '1' become a conducting state, respectively, and since an output exists in weighting registers R1-RN connected to them, respectively, an adder 4 outputs a reference signal value adding their maximum (N+1) pieces, and a comparator 1 compares it with an analog input signal A and when the signal A is larger, a positive signal is generated. When the signals D1-DN of a digital signal register 2 are all '1', and the comparator 1 has generated the positive signal, A>=V is formed, therefore, an overflow detecting circuit 5 detects it as an overflow and generates an overflow signal O.

Title: Address converter
Inventor: KONO YASUFUMI
IPC: G06F12/16
Filed: 1986-10-13
Abstract: PURPOSE:To protect a data exchanging memory by dividing this memory according to the information on a position where a CPU board is attached and inhibiting the accesses given from other CPU boards. CONSTITUTION:The higher 4 bits of an address signal of a CPU are inputted to an input terminal 11 of an address decoding circuit 1 and an output terminal 12 is set at '1' when the value of said 4 bis is equal to '8'. An encoding circuit 2 encodes the attaching position of a CPU board and delivers this encoded value to an output terminal 22. A data selecting circuit 3 supplies the higher 4 bits of an address signal of the CPU to an input terminal 31 and the output signal of the circuit 2 to an input terminal 32 respectively. Then the circuit 3 delivers the signal supplied to an input terminal 32 when a selection terminal 34 is equal to '1' and then outputs the signal inputted to the terminal 31 when the terminal 34 is equal to '0'. Thus a data exchanging memory is divided by the slot position of the CPU board. Then it is impossible to give accesses to the same area from plural CPU.

Title: Double-tank type fryer
Inventor: SAWADA MASAYOSHI
IPC: A47J37/12
Filed: 1990-09-12
Abstract: PURPOSE:To raise gradually the temperature of frying oil received in two oil tanks with high temperature frying oil after heat exchange and obviate the dispersion of the temperature of frying oil in the two oil tanks for equalizing the same by circulating the frying oil between the oil tank and a heater with a pump to heat the frying oil while it passes through a heat exchanging path. CONSTITUTION:A burner 14 is controllably run according to the temperature condition of frying oil in a lower oil tank 2. For example, when the lowered temperature of frying oil is detected by a temperature sensor 27, a controller is operated to increase a combustion heat amount of the burner 14. A pump 17 is under the normal running condition and forcibly circulates the frying oil. The frying oil in an upper oil tank 1, when its temperature is in a proper value, is circulated between the oil tank 1 and a circulating path 22. When the frying oil temperature is lowered lower than the proper one, a temperature sensor 26 detects it to open an automatic controlling valve 25 through the controller so that a portion of thigh temperature frying oil discharged from the pump 17 flows down to the circulating path 22 side through a branched path 24 by a pump 23 and flows into the upper oil tank 1 to raise the surrounding frying oil temperature. An automatic controlling valve 25 is operatively closed when the frying oil temperature in the oil tank 1 is returned to the proper value.
