Title: Magneto-optical overwrite system
Inventor: IWANAGA TOSHIAKI
IPC: G11B11/10
Filed: 1989-04-06
Abstract: PURPOSE:To generate a high frequency magnetic field by providing a magnetic field modulation coil system having a resonance frequency confirming with a carrier frequency of a phase modulation inputted from a phase modulating circuit system, and forming a resonance circuit by a magnetic head. CONSTITUTION:A phase modulating circuit system 2 superposes and applies a high frequency current brought to two phase modulation to a magnetic head in accordance with binary data of a recording information signal. In this case, a magnetic field modulation coil system 3 sets a frequency of the recording information signal brought to two phase modulation so as to become a resonance frequency. The coil system 3 is constituted of the inductance which generates a high frequency magnetic field and shaped to a shape being appliable onto the medium surface and a capacitor for constituting a resonance circuit. In the resonance frequency, the magnetic field modulation coil becomes only a pure resistance, and a current can be allowed to flow a great deal by a high frequency, therefore, a strong magnetic field can be generated. Accordingly, a high frequency magnetic field can be applied from a disk substrate side, and magnetic field modulation overwrite can be realized by using a double disk.

IPC: B22D1/00
Filed: 1981-06-03
Abstract: PURPOSE:To provide a titled device that can check whether the addition of an additive  is correct or not in a position apart from the supply end for the additive by detecting  the flow rate of the additive between an additive charger and the gas force-feeding  part at the other end of an additive supply pipe, and detecting the gaseous pressure in  the supply pipe. CONSTITUTION:The start of charging by tilting of a charging ladle 4 is detected with  an IR ray thermometer 21, and an opening-closing damper 14 is opened by the signal  thereof to charge 13a an additive into a supply port 10. The flow rate thereof is detected with a flow rate detector 15. The additive charged into the port 10 is ejected from  a gas force-feeding part 7 through a supply pipe 6 then out through the opening 6a at  one end thereof so that it is added into the molten metal released from the discharge  end 2a of a charging spout 2 via a chute 3 from a ladle 4. The charging state of the additive into the port 10, that is, the charing flow rate of the additive, is measured  with the device 15 and its processing device 18, and whether the charging flow rate is  in a normal range or not is checked. If it is out of the range, it is displayed that the charging is in an abnormal state. Molten metal is charged from the spout 2, and a prescribed amt. of the additive is added to this molten metal, thence it is cast in a rotating metallic mold 1.

Title: Heating device
Inventor: WASHIYAMA NARITATSU
IPC: G03G15/00
Filed: 1983-05-17
Abstract: PURPOSE:To improve rise of a pressing roller temperature so that it reaches quickly a fixable state by driving the pressing roller to make it contact by pressing, when a temperature of a heating roller is rising. CONSTITUTION:When a heater of a heating roller is turned on, and a roller surface temperature rises up to T4, a pressing roller contacting with the heating roller is rotated. As a result, a pressing roller temperature rises up to T5, therefore, a heating roller temperature is still T3 and lower than a temperature T2 obtained after reaching a stationary state, but a fixation is possible already. When the rotation is stopped, the pressing roller temperature drops to T6, and thereafter, rises up to T7 or above by a heat conduction from the heating roller and the inside heater. The heating roller is held at a high temperature set value T1, and thereafter, set to a low temperature set value T2 at the stage in which the pressing roller has risen up to T7.

Abstract: PURPOSE:To decrease the spacing of a head and recording medium by the specific constitution consisting the head of the 1st and 2nd nonmagnetic substrates, the 1st core stock pieces, and the 2nd core stock pieces joined to form a gap between said stock pieces. CONSTITUTION:This head has the 1st and 2nd nonmagnetic substrates 11, 12, the 1st core stock pieces 13, 14 which are joined to said substrates and are wound with coils, and the 2nd core stock pieces 16, 17 which are provided on both faces of said core pieces via a magnetic shielding material 15 consisting of glass or silver solder in-between. The head is constituted by joining the 2nd core stock pieces to the 1st core stock pieces on the nonmagnetic substrates to as to form gaps 18, 19, 20. The gaps 19, 20 limit both ends of the contact locus of the gap 18 with the recording medium. The spacings between the gap 18 for recording and reproduction and the gaps 19, 20 for erasure can control the thickness of one or two layers of the magnetic sheet and since there is particularly no need for taking mechanical strength into consideration, the spacing can be narrowed down to several 10mum. The spacing quantity between the magnetic head and the recording medium is thereby decreased.

Title: Current detecting circuit
Inventor: UMEZAWA KIYOSHI
IPC: G01R19/165
Filed: 1992-04-08
Abstract: PURPOSE:To provide a circuit for detecting a current over a wide range from a microcurrent to a high current by inserting a semiconductor diode into an objective circuit to be detected and connecting a voltage discriminator across the semiconductor diode. CONSTITUTION:A semiconductor diode 11 is inserted into an electric circuit 10 and a voltage discriminator 12 is connected across the diode 11 through lead wires 13, 14. When a current flows through the circuit 10, the discriminator 12 delivers an ON or OFF signal depending on the magnitude of the voltage across the diode 11. The voltage-current characteristics of the diode 11 rises abruptly at a threshold voltage of about 0.6V and thereby the voltage across the diode 11 is substantially constant regardless of the magnitude of current. Consequently, the presence of current can be decided stably from a microcurrent to a high current using a single element.
