Title: Method of correcting photomask by polishing
Inventor: YANAGIDA KIMIO
IPC: G03F1/72
Filed: 1980-08-04
Abstract: PURPOSE:To heighten the efficiency of correction of an acute angled flaw on a photomask made by using a reticle, by rotating a hemispherical felt while thrusting it at the flaw to change it into a hemispherical recess to reduce the diffusion of light. CONSTITUTION:A stage 13 is horizontally mounted with supports 15 in a cup- shaped cover 12 whose top is open. A photomask 1' having an acute flaw to be corrected is placed on the stage. A nozzle 14 is protruded in the cover 2 to feed an abrasive material to polish the mask 1'. The cover 12 can be moved back and forth and right and left. A polisher comprising a motor 7, a gear unit 9 and a rotary shaft 10 is supported by a stand 8 so that the polisher is located over the mask 1'. A hemispherical polishing felt 11 is attached to the rotary shaft 10. The mask 1' is displaced to thrust the felt 11 on the flaw part of the felt to polish it. The acute angled flaw (a) is thus changed into a gentle recess (b) to reduce the diffusion of light.

Abstract: PURPOSE:To eliminate the need for a waveguide tying a primary radiator and a radio equipment by connecting the both directly in a reflecting antenna system utilizing a rotationally symmetric concaved face reflection mirror. CONSTITUTION:An inner cylinder 12 is fixed coaxially in the inside of an outer cylinder 11 by using a support 13. A radio equipment 14 having a high frequency section and the primary radiator 15 connected directly to said radio equipment 14 are mounted in the inside of the inner cylinder 12. Since the primary radiator 15 is connected directly to the radio equipment 14, no waveguide is required. A terminal board 16 is fitted to one end of the outer conductor 11 and a reflection mirror 17 having a rotationally symmetric concaved face is fixed to the terminal board 16. On the other hand, a radome 18 is fitted to the end of the outer cylinder 11. Since the radome has only to be fitted to the end of the outer cylinder 11, the shape is simplified.

Title: Monitoring device for superconducting coil
Inventor: TASHIRO IKUO
IPC: H02H7/00
Filed: 1985-05-20
Abstract: PURPOSE:To detect the quenching of an AC excited superconducting coil with good response, by taking a voltage signal between the intermediate tap of a resistor voltage divider, which is connected to the superconducting coil in parallel and the intermediate tap of the superconducting coil. CONSTITUTION:When quenching is yielded in a superconducting coil 1, a state, in which a resistor R is equivalently connected to the superconducting coil 1 in series, is obtained. When the impedance of the superconducting coil 1 becomes equal to the composite value of the inductance and the resistance, the phase difference between an input signal Es and a reference signal Is becomes 90 deg. inevitably. Therefore, the output Vp of an averaging circuit 15 does not become zero but becomes a certain value. When the output Vp exceeds a specified level, the operation of a gate circuit 16 is stopped. Therefore, current supply to the superconducting coil 1 is stopped, and the countermeasure for the quenching is executed.

IPC: H04N5/455
Filed: 1993-05-10
Abstract: PURPOSE:To obtain an AM demodulator prevented from generating locking deviation at the time of either turning on a power supply or changing a channel. CONSTITUTION:A detection circuit 2 demodulates an input AM modulation signal by using a carrier reproduced by a phase lock loop consisting of a VCO 3, a comparator 4 and an LPF 7. The time constant of the LPF 7 is controlled by a horizontal period key pulse generated by a key pulse generating circuit 9. Since a pulse width changing circuit 10 gradually narrows the pulse width of the key pulse at the time of turning on the power supply or changing a channel, the phase lock loop is gradually transferred from an average value PLL up to a keyed PLL.
