Title: Noise reducing circuit
Inventor: KURIYAMA KIYOSHI
IPC: G11B20/02
Filed: 1988-01-12
Abstract: PURPOSE:To keep the continuity of a voice signal by inserting the bias-recorded- and-reproduced voice signal in the discontinuous period of a modulated wave originated in a drop out and the rotational head switching of a video tape recorder. CONSTITUTION:A frequency modulated voice signal D is added to an input terminal 1 and demodulated with a demodulator 3 through a detector 2. The demodulated signal is amplified with an amplifier 4 and added to an amplifier 7 through a switch 5. Here, when a modulated wave has a drop out, a noise is generated at a demodulating output E of the demodulator 3. However, when it has the drop out, the detector 2 works, turns off the switch 5, and moreover, turns on the switch 5. Thus, the voice signal from an input terminal 9 is amplified without transmitting the noise to the amplifier 7, and the voice signal to reduce the noise from an output terminal 8 can be always obtained as an output F from the amplifier 7.

Abstract: PURPOSE:To obtain a gas laser device which is less sensitive to the tilt of a reflecting mirror, easy to control the tilt of the reflecting mirror and stable in performance by forming a laser resonator on a recessed part and a projected part respectively in terms of one dimension belonging to a longer dimension in a cross section of a discharge space, and constituting an unstable resonator of a negative branch. CONSTITUTION:This resonator is an unstable resonator of a negative branch comprising a combination of mirrors 50 and 51 in terms of one dimension belonging to a longer dimension in a cross section of a discharge space or in the direction of A. In terms of one dimension of a shorter one or in the direction of B, it serves as an optical waveguide resonator. Furthermore, the unstable resonator of negative branch is designed to deviate a laser light axis from the central axis of the discharge space in order to take out a laser beam from one end 671 of a longer dimension of the cross section of the discharge space. The construction of this unstable resonator of negative branch produces a focus point within the resonator wherein the light does not come into focus in one point only but along a line, and thereby prevents the occurrence of any problems induced by the concentration of light and exerts the maximum advantage enjoyed by the unstable reflector of negative branch which is less sensitive to the tilt of the reflecting mirror and improves the stability of the resonator.

IPC: H01L21/768
Filed: 1994-01-20
Abstract: PURPOSE:To reduce the absolute steps in an uppermost oxide film by forming an isolation oxide film partly differing in height above semiconductor substrate surface. CONSTITUTION:A polysilicon film 3 is etched using a nitride film 4 and resist 21 as a mask. Then a silicon substrate 1 is oxidized by heating using the nitride film 4 as a mask to simultaneously form isolation oxide films 6a and 6b. Since the isolation oxide film 6a is formed by oxidizing both the polysilicon film 6a and the silicon substrate 1, its surface is higher than that of the isolation oxide film 6b formed by oxidizing only the silicon substrate 1. After the deposition of an oxide film 7, a polysilicon film 8 doped with phosphorus to form wiring is deposited, and then patterning is performed to form a desired pattern. This reduces the absolute steps in upper layer films and extends the common focus margin in a phototype process.

Abstract: PURPOSE: To precisely control the cooling of a steel strip, prevent the dispersion of a material quality and improve the quality of the steel strip by making it possible to lower a spray nozzle at the time of the high pressure supply of cooling water, and making it possible to elevate the spray nozzle at the time of the low pressure supply of the cooling water. CONSTITUTION: This cooling device is equipped with a pipe lamina flow nozzle 3 whose cooling capacity is almost constant and a spray nozzle 13 capable of controlling the cooling capacity. Low pressure cooling water is supplied to the pipe lamina flow nozzle from a cooling water supply pipe 2, and is made to flow down on a steel strip 15, which is passed through a hot run table after a hot finish rolling, and the steel strip 15 is cooled. When elevating a rack 8 by a fluid pressure cylinder 6, the spray nozzle 13 is elevated to stop the flowing-out of the low pressure cooling water. When supplying high pressure cooling water to the cooling water supply pipe 2, the flowing-down of the cooling water from the pipe lamina flow nozzle 3 is stopped by the operation of a check valve 4, and when lowering the rack 8, the cooling water is jetted from the spray nozzle 13.  In this way, the cooling of the steel strip 15 can be precisely controlled.

Abstract: PURPOSE:To obtain an image of the proper density at all times by adjusting the pressure to a supporting member of a thermal head on the basis of the detecting result of the density of an image printed onto a recording paper. CONSTITUTION:The density of an image on a line is detected by density detectors 55a, 55b, 55c, and the detecting values are compared in a density comparison circuit 56, thereby to obtain the difference of the detecting values. When the difference is transmitted to a control circuit 57, the moving direction and moving amount of a thermal head 10 to obtain a proper image density are calculated and the calculated values are fed to a motor drive circuit 58 for adjustment. As a consequence, either an adjusting motor 42 or 43 is actuated to drive an eccentric cam 33 or 34, thus pressing pressuring plates 31, 32, or the thermal head 10 is allowed to slide together with a thermal head holding member 25 by the elasticity of pressuring springs 29, 30. Accordingly, since the position and inclination of the thermal head 10 to a platen roller 16 are adjusted, the pressure of the thermal head to the platen roller 16 is adjusted so that the image density is adjusted to be uniform.
