IPC: G11B5/024
Filed: 1982-02-17
Abstract: PURPOSE:To make an oscillating coil consisting of a primary winding, a secondary winding, etc. unnecessary and to make the device miniaturized, by using the winding part of an erasing head as the oscillation coil for generating an AC erasing voltage. CONSTITUTION:In respect to a winding 12 of a core 11 of the erasing head of the double gap system consisting of magnetic materials such as ferrite, the terminal of one of two windings wound in one direction is connected to the start of the other, and this connection part is connected to a power source voltage terminal 13 through a lead wire 14. The winding 12 is connected to a push-pull oscillator 16 consisting of a hybrid IC and is operated as an oscillation coil of the push-pull oscillator 16. Two-fold power source voltages VCC having opposite phases are applied across both terminals of the winding 12, and an erasing voltage having about 4-fold P-P value is applied. A polypropylene capacitor 17 is provided between both terminals of the winding 12, and the oscillation is performed by the resonance between this capacitor 17 and the winding 12 to generate an erasing magnetic flux in front of the gap of the erasing head; and thus, sufficient erasing is performed.

Inventor: HARAGA HISATO
IPC: A61H23/00
Filed: 1990-01-31
Abstract: PURPOSE:To precisely execute the position control of an exhaust nozzle by moving a valve body to a valve seat in a fully closed position, allowing it to abut thereon and allowing it to execute step-out, whenever the exhaust nozzle is operated by depressing an operation switch. CONSTITUTION:When an operation switch is turned on, exhaust nozzles 2-4 are moved in the closed direction, and a valve body 22 is allowed to abut on a valve seat 21f, and also, it is allowed to execute step-out. Thereafter, the exhaust nozzles 2-4 are moved in the closed valve direction, stopped in a fully opened position, and in the case the exhaust nozzles 2-4 move to a fully opened position and a valve driving detection sensor S1 is turned on, the initial operation is completed, and thereafter, a mild blow operation is started. However, in the case the valve driving detection sensor S1 is not turned on, it is decided that a nozzle valve body opening/closing operation motor M1 is abnormal and the motor is stopped. In such a way, even in the initial operation at the time of operation switch, abnormality of the exhaust nozzles 2-4 can be detected surely, therefore, the certainty and the safety of a blow operation can be secured in advance.

Filed: 1994-02-22
Abstract: PURPOSE:To constitute a beam flood device whose read depth is deep by providing a zone plate with a diffraction grating diffracting a divergent light beam from a light source. CONSTITUTION:The zone plate 3 is a disk on which many concentric circular shaped diffraction gratings are formed, and intervals of these gratings become narrower with distance from a center of a concentric circle, and the central line of the concentric circle of the diffraction grating becomes an optical axis 4. When the divergent light beam with a fixed wavelength radiated from the light source 1 arranged on the optical axis 4 is made incident, the ring band plate 3 diffracts it, and converts a part of it to a +1st-order diffracted light beam and a +2nd-order diffracted light beam to emit. The +1st-order diffracted light beam and the +2nd-order diffracted light beam advances so as to be most converged on a converging point 11 and the converging point 21 on the optical axis 4 respectively. A range where a bar code with a prescribed bar width is readable is constituted of two of the range 12 and the range 22 around the converging point 11 and the converging point 21 respectively, and they are made adjacent by properly selecting the periodical distribution of the diffraction grating of the ring band plate 3.
