Title: Circuit for detecting stain of tape recorder head
Inventor: FURUKAWA TAKESHI
IPC: G11B5/455
Filed: 1987-08-20
Abstract: PURPOSE:To immediately detect head stain when it is generated in performing signal recording by switching and connecting a rotary magnetic head to a reproducing system only for a short time at a prescribed time in one field period. CONSTITUTION:Recording and reproduction change-over switches 3 and 4 are switched and controlled by a switching control circuit 7 at a prescribed period at the time of recording a signal, and they are switched only for a short time for a recording system 6 side to the reproducing system 5 side at the prescribed period in one scanning period where one signal track is to be formed. At the reproducing system 5, a head stain detecting means to generate a stain detecting signal representing the generation of the head stain when no reproducing output with a level over than a prescribed level can be obtained from each of the magnetic heads 1 and 2 in a short period is provided. Thus, it is possible to detect the head stain immediately generated while the recording of the signal is performed by the head stain detecting signal.

Title: Gas laser oscillator
Inventor: HAMAGUCHI MASAHIRO
IPC: H01S3/097
Filed: 1993-08-23
Abstract: PURPOSE:To prevent the attachment of dust to an optical system. CONSTITUTION:The gas in wind guides 8 and 9 flows to the outside of the wind guides 8 and 9 through a hole 10, which is the open part of the wind guide 9. The gas is flows into the inner parts of the wind guides 8 and 9 again through a gap, which is another open part. Such a path is generated. The amount of the wind flowing through this path is slight. Therefore, dust gathers in the drift part in a chamber 1 at the outside of the wind guides 8 and 9. The amount of the dust, which returns into the gas circulating path formed in the inner parts of the wind guides 8 and 9, is less. Therefore, the dust can be quickly removed from the gas circulating path.

Title: Metal covered wiring structure
Inventor: TSUNENARI YOSHITSUGU
IPC: H01L27/04
Filed: 1989-08-10
Abstract: PURPOSE:To prevent the deterioration of electrical characteristics due to a fluoride on the interface between metal films by a method wherein the title structure is constituted into a structure wherein the upper surface and the side surfaces of a wiring member, which contains Al as its main component and is formed on an insulating film, are covered with a first metal film and moreover, the periphery of the first metal film is covered with a second metal film. CONSTITUTION:A metal covered wiring structure is constituted into a structure wherein the upper surface and the side surfaces of a wiring member, which contains Al as its main component and is formed on an insulating film, are covered with a first metal film, on which a halide is hardly produced, and moreover, the periphery of the first metal film is covered with a second metal film. In this case, the periphery of an Al wiring member 102 formed on an insulating film 101 is covered with a thin copper film 103 of a thickness of about 200A and moreover, the periphery of the film 103 is covered with a tungsten film 104 of a thickness of 500A. Moreover, when a heat treatment is performed at 400 deg.C for 30 minutes after the film 104 is deposited, alloying occurs on the interface between the surface of the Al wiring member 102 and the film 103. Thereby, a connection failure at the time of interlayer connection in a multilayer wiring product, which is caused by the formation of a fluoridation of the Al, can be prevented.

Title: Tracking device for travelling object using carrier suppressing modulated wave
Inventor: FUJIWARA TOMOHIRO
IPC: G01S3/42
Filed: 1981-12-23
Abstract: PURPOSE:To reduce the generation of noises to enable a phase wave detection and to prevent the lowering of the tracking accuracy, by converting both the reference and error signals into carrier waves in narrow band and then performing a phase wave detection with use of the carrier wave of a narrow band. CONSTITUTION:A data receiving part 17 converts the frequency through a frequency converter 7 and delivers a demodulation data 19 and a reproduced carrier wave 18 from a time axial waveform 23 which is converted into a signal of a frequency fIF. An adverse modulator 16 gives an adverse modilation to an input error signal 20 by means of a clock, and a data 19 is fed to the modulator 16. Therefore the clock 19 is multiplied by the signal 20 and the phase of the signal 20 is inverted in an inverting period of the clock 19 by an adverse modulating action. As a result, the output 21 delivered from the modulator 16 is turned into a carrier component of the frequency fIF. The error signal which is turned into a narrow band signal after passing through a BPF22 is supplied to phase wave detectors 13 and 14 respectively. Thus a wave detection is possible with suppression of noises.

Abstract: PROBLEM TO BE SOLVED: To improve living comfortability and safety by damping vibration of a building, or the like due to an earthquake, wind, or the like by replacing horizontal vibration kinetic energy of a structure to a form of rotational operating energy by converting it to rotational energy of a flywheel. SOLUTION: A bidirectional rotational damping mechanism is provided in parallel with laminated rubber, etc., as a base isolation device between a structure and the ground. It is constituted by combining an X directional rotational damping mechanism 11 and a Y directional rotational damping mechanism 12 and individually converts rectilinear motion on both of XY directional flat surfaces to rotation of a flywheel. Accordingly, a rack 5 is manufactured in a mechanism to give torque to rotating gears 6, 7, and torque in the reverse rotational direction is constituted to slide. Consequently, transmission gears 8, 9 transmit torque only in the same direction by reciprocal motion of the rack 5, and the flywheel is rotated only in one direction.  Additionally, even when the rack 5 stops, the flywheel 4 keeps rotating, discharging accumulated rotational kinetic energy little by little by the amount of friction of a bearing and absorbs vibration of the structure.

Abstract: PURPOSE:To cover sufficiently variation in the quantity of light at an object position due to the depth of photographic distance by varying the distance between the optical axis of irradiation of an endoscope and the axis of rotation of a rotary shutter and controlling an irradiation time. CONSTITUTION:The shape of a shutter blade 6 is so designed, for example, as shown in a figure that the blade transmission time (corresponding to the peripheral length at each radial position of a shutter blade) of irradiated light from a light source lamp 3 is varied by utilizing the peripheral speed difference at each radial position when the rotary axis 7a of the shutter blade for a illumination light axis 0 shifts in position, namely, when the gap between both axis 0 and 7a varies. Namely, the respective positions on the radial line (cutoff reference line 7a) of the shutter blade 6, e.g. points (a), (b), and (c) are made different in circumferential length (irradiated light cutoff length) by varying the curvature of the outer edge 6b of the blade 6. Consequently, variation in the quantity of light between a close point and a distant point due to the large depth of an object position of observation (photography) is dealt with sufficiently.
