Title: Magnetic disk device
Inventor: YAJIMA TAKAYUKI
IPC: G11B20/10
Filed: 1990-04-18
Abstract: PURPOSE:To prevent such a defective case where a data writing job is interrupted owing to a malfunction caused by the noises, etc., by inputting a write unsafe signal to a signal generating circuit after transmitting it through an LPF. CONSTITUTION:A 2nd write gate signal *WGT2 is sent to a data write circuit in order to inhibit the write of data into a storage carrier based on a 1st write gate signal *WGT1 received from a control means 1 and showing a write instruction and a write unsafe signal WUS received from a write abnormality detection means 2 which detects the abnormality of the data write circuit. At the same time, a write fault signal *WFAULT is inputted to a signal generating circuit 3 which produces the signals to the means 1 in order to cancel the write instruction with use of the signal WUS. In this case, the signal WUS is previously transmitted through an LPF 4. Thus the circuit 3 never transmits the signal *WFAULT despite the presence of noises, and it is possible to prevent such a case where the write instruction is cancelled by mistake and a data writing job is interrupted.

Title: High-sensitivity magnetic-field detecting device
Inventor: ODAWARA NARIKAZU
IPC: H01L39/22
Filed: 1998-04-14
Abstract: PROBLEM TO BE SOLVED: To obtain a high-sensitivity magnetic-field detecting device by which the measuring accuracy of a reference signal can be enhanced, by a method wherein a phase detection circuit is constituted of a plurality of phase detectors, and the phase of the reference signal of at least one phase detector can be changed over. SOLUTION: A reference-signal inverting circuit 15 and a reference-signal inverting switch 16 are installed across a first phase shifter 13 and a second phase detector 12. Square waves from an oscillator 40 are phase-shifted to a phase-shifting amount of θ=90 deg. by the phase shifter 13 so as to be sued as a reference signal of the phase detector 12. The reference signal of the phase shifter 12 becomes a signal which is passed through an inverting circuit 15 when the inverting switch 16 is in an on-state, and it becomes a signal which is not passed through the inverting circuit 15 when the inverting switch 16 is in an off-state.  When the phase difference between a modulation signal which is amplified by an amplifier 30 and which comes from a DC drive- type superconducting quantum interference device 20 and an output signal from the oscillator 40 is in a range of θ=0 deg. to θ=90 deg. or in a range of θ=180 deg. to θ=270 deg., the inverting switch 16 is turned on. When the phase difference is in a range of θ=90 deg. to θ=180 deg. or in a range of θ=270 deg. to =360 deg., the inverting switch 16 is turned off.

Abstract: PURPOSE:To reduce vibration and noise given to a hull from a diesel engine, and prevent and relieve the vibration by installing the first and second stopper brackets which are erected on a foundation floor and a middle base plate so that they may be fixed on the middle base plate and the front and rear ends or right and left edges of the middle base plate through vibration-proof rubbers. CONSTITUTION:This vibration-proof device is of double vibration-proof structure which supports a base plate 2 on which a diesel engine 3 and a generator 4 are installed through a vibration-proof rubber 6b on upper stage, a tall middle base plate 5 with a large mass and a vibration-proof rubber 6a on lower stage. Therefore, while it restrains the vibration in the directions of front and rear, and right and left, it reduces the vibration in a vertical direction to much more extent in comparison with a conventional one. Moreover, the four sides of the middle base plate 5 are connected to the foundation floor 1 through eight first stopper brackets 7, and the four sides of the base plate 2 are connected to the middle base plate 5 through eight second stopper bracket 8. It is thus possible to prevent and relieve the vibration in the directions of front and rear and right and left of the base plate 2, because the spring constant in the shearing direction of the vibration-proof rubbers 6 may be increased exfremely.

Title: End structure of bundle fiber
Inventor: KURAUCHI NORITAKA
IPC: G02B6/04
Filed: 1980-07-28
Abstract: PURPOSE:To prevent a drop of quantity of light at a margin part, by constituting an end of the marginal part of a bundle fiber, of a diffusing surface having a suitable rough surface. CONSTITUTION:An incident angle of a light beam 14 which is made incident to an end 12 of an image fiber 11 through a condenser lens 13 has a tendency to become large in the marginal part, therefore, in case of a picture transmission line using an image fiber, the peripheral quantity of light is apt to be short. As for a part where a drop of the quantity of light is remarkable by being prescribed by the number of openings of the lens and the image fiber, the quantity of light is secured to some extent or more by forming a rough surface having the roughness between the diameter of a fiber strand and the optical wave length, and diffusing the light beam, and the overall coupling efficiency is elevated by compensating a short quantity of light in the marginal part.

Filed: 1991-04-10
Abstract: PURPOSE:To produce the optical recording medium which is lessened in the degradation in recording capacity and allows stable reading out of information by improving the accuracy of the position control at the inner peripheral end of a light absorptive layer. CONSTITUTION:The optical recording medium is formed by forming the light absorptive layer by spin coating only on the outer peripheral part on a circular substrate to form a ROM part exclusive of its central part, then forming a reflection layer over the entire surface of the substrate.

Title: Measuring device for electric characteristic
Inventor: SATOU TERUYA
IPC: G01R31/26
Filed: 1984-05-24
Abstract: PURPOSE:To improve the reliability and durability of wafer probers by enabling electrical connection or separation of an edge sense needle and a sense circuit by a method wherein a detecting means is connected to the power source via transformer, and a controller which cuts off the voltage of the power source according to the variation of transformer current is provided. CONSTITUTION:Prior to the test of a wafer 1, an oscillator 9 makes oscillation at a required frequency. When the wafer 1 is moved to a required testing position in this state, the movable part 3 of an edge sense needle is separates off from the fixing part 4 of said needle by being pushed upward on an increase of the wafer 1 if the movable part 3 is located on the wafer 1. Observation of this situation from the side of the oscillator 9 shows an increase in the primary side current of the transformer 7 because of no flows of the secondary side current of the transformer 7. In other words, the state of connecting the edge sense movable part 3 to the fixing part 4 is detected by an ampere meter 8, and the result is transmitted to the controller 10; then, the oscillator 9 stops oscillation on its command. Accordingly, the wafer 1 comes out of effects of the sense circuit and is subjected to wafer test.
