Title: Magnetic disk device
Inventor: SAKAI YOSHIAKI
IPC: G11B19/20
Filed: 1984-02-08
Abstract: PURPOSE:To enable quick start of recording and reproducing and power saving by controlling a motor for disk rotation and a motor for held shifting independently. CONSTITUTION:Power sources of the motor 2 for disk rotation and the stepping motor 8 for head shifting are controlled independently by two different transistors 20, 21. Consequently, power supply fitted for respective circuit becomes possible, and recording or reproducing can be started quickly. As the motor 2 for disk rotation and stepping motor 8 for head shifting can be made of independently for power saving without making them off simultaneously, close control for power saving becomes possible. Even when on control signals are given to the first and second transistors 20, 21 simultaneously, difference is generard in on time. Accordingly, total starting current becomes small.

Filed: 1988-02-02
Abstract: PURPOSE:To provide excellent water leak preventive effect and fabricate in a short time by fitting a cord-shaped packing in a groove consisting of steel rod ribs surrounding the broken part. CONSTITUTION:A main member of a curved backing plate 1 is fabricated from a metal sheet, and in this example, the outside surface and inner surface of a repair pipe are composed of a flat steel plate 2 bent into substantially the same radius of curvature, steel rod ribs 3a, 3b arranged at the inner surface 2a of this flat steel plate 2 so as to surround the broken part, and a cord-shaped packing 5 fitted in a groove 4 consisting of these ribs. This prevents the cord- shaped packing 5 from dislocation and breakage and stops the water easily even though there is much leakage of water when the broken part of the troubled pipe is contacted.

IPC: C08K3/00
Filed: 1983-02-14
Abstract: PURPOSE:To provide a resin uniformly containing a large amount of an oil without causing separation, and giving a molded product having excellent physical properties, by compounding a lubrication oil and a specific ultrafine amorphous anhydrous silica to a resin. CONSTITUTION:Pellets of a thermoplastic resin used as a vehicle are added with 1-40wt% of a lubrication oil (e.g. mineral oil, fatty acid, etc.) and 20-100wt%, based on the lubrication oil, of ultrafine amorphous silica anhydride as a thixotropic agent. The mixture is stirred first under high shear rate to convert the mixture to a sol, the shear rate is lowered gradually to effect the gelation of the sol, and the gel is stirred in the absence of shearing force to obtain gelatinized mixture. The mixture is kneaded under high shear rate and heating to make the gel to sol and at the same time to melt the pellets to obtain a molten mixture, which is extruded and formed to a definite shape. The thermoplastic resin is polyphenylene sulfide resin, polyacetal resin or polyamide resin.

Title: Satellite broadcast receiver
Inventor: OSHIMA TAKASHI
IPC: H04N5/44
Filed: 1991-01-22
Abstract: PURPOSE:To realize the satellite broadcast receiver in which setting of an azimuth angle and an elevating angle or the like of a BS antenna are simplified and an angle setting jig is made at a low cost. CONSTITUTION:A C/N detection circuit 17 of a BS tuner 4 detects a level of a noise component included in an output signal of an FM demodulation circuit 8 and generates a DC C/N proportional to the noise component. That is, the DC C/N voltage is proportional (or corresponding) to a noise level (C/N) of an input signal received by a BS antenna 1. Then the DC C/N voltage is selected by a voltage changeover circuit 18 and superimposes the voltage onto a signal at a BS-IF signal input terminal and sends the result to an angle setting jig 19 of the above BS antenna in place of a DC power supply voltage generated by a BS converter power supply circuit 13 and adjusts and sets an azimuth angle and an elevating angle or the like of the above BS antenna 1 so that a DC voltage of a DC voltmeter 20 is minimized (maximized).

IPC: H02P8/38
Filed: 1997-02-04
Abstract: PROBLEM TO BE SOLVED: To provide a rotary drive mechanism in which abnormal rotation of a stepping motor can be detected surely through a simple structure. SOLUTION: Abnormal rotation of a stepping motor 2 can be detected surely through a simple structure by making a decision whether the number of pulses in forward rotational direction detected after detection of the switching of a switch 7 in the forward or reverse rotational direction of a stepping motor 2 before detection of switching of the switch 7 in the reverse rotational direction, matches the number of pulses in reverse rotational direction. In this regard, the switch 7 is provided in a motor drive circuit 2a and variation of an electric signal from motor drive circuit 2a due to switching of the switch 7 is detected. Since no additional wiring is required to be connected with the switch 7, the structure can be simplified.

Abstract: PURPOSE: To reduce the warp of a substrate and raise production yield, by setting a gradient on the P concentration distribution of a tapered GaAs 1-x P x  layer which constitutes a light emitting diode and by cancelling the stress of the layers which constitute the diode.  
     CONSTITUTION: A tapered Ga 1-x P x  layer 2 and a GaAs 1-x P x  layer 3 are grown and laminated on a GaAs layer 1 to compose a light emitting diode. To reduce the warp of the substrate of the diode, the layer 2 is set at a P concentration gradient. the first stress due to the thermal expansion coefficient difference between the layers 1, 2, the second stress due to the lattice constant difference between the layers and the third stress due to the introduction of dislocation based on the lattice constant difference are caused to cancel one another to reduce the stress. As a result, resultant stress 10 due to lattice strain, misfit dislocation and gradient dislocation and convexly warping stress 11 due to the thermal expansion coefficient difference and P concentration gradient in the layer 2 cancel each other so that resultant stress as shown by a curve 12 remains.

IPC: H03H11/02
Filed: 1993-02-10
Abstract: PURPOSE:To widen the operation band of a microwave and to make the scale of the circuit small by using the phase filter of a three port circuit transmitting or interrupting a signal based on the phase of the signal. CONSTITUTION:This filter is made up of a control voltage generator 1 and an output control circuit 2. In the control voltage generator 1, a microwave mixer 10 extracts a base band signal VB proportional to a cosine {cos(theta)) of a phase difference between an input signal VS and a reference signal VR, (N-1) sets of multipliers 21-24 form components of cos<2>(theta), cos<3>(theta),...cosN(theta), and N-sets of adders 41-45 add sequentially the cosine components and a control voltage (theta) is obtained as a result. On the other hand, the output control circuit 2 uses a microwave switch 50, which is switched on or off depending whether or not the control voltage (theta) exceeds a threshold voltage, resulting that the output of the phase filter is equal to the input signal VS or zero.
