Title: Tracking control method of fixed magnetic disk storage device
Inventor: GAYA HIROKI
IPC: G11B21/10
Filed: 1989-05-26
Abstract: PURPOSE:To improve the productivity by generating a tracking control signal part with a servo pattern and a block pattern and deciding the position of a data head from a read voltage ratio. CONSTITUTION:Two arrays of servo patterns 5 which continue radially are written in respective sectors provided on a hard disk. Then proper positions of one pattern 5 are erased to cut the pattern and form block patterns 6, which form tracking control parts 4 with the other pattern 5. Here, the other pattern 5 is recorded continuously, so the pattern is constant irrelevantly to the position of the data head 7. Further, the pattern 6 varies in the area ratio to travel track width as the head 7 moves, so its read voltage also varies. For the pur pose, the head 7 is moved and positioned so that the read output ratio of the patterns 5 and 6 becomes a specific value, and consequently a read can be made by the fixed magnetic disk device main body and the productivity is improved.

Title: Rotating variation reducing method of motor
Inventor: SUGISHITA TAKAHARU
IPC: H02P29/00
Filed: 1984-06-28
Abstract: PURPOSE:To reduce the variation in the rotation by controlling the variation in the intrinsic rotation during one rotation of a motor caused by the variation in the torque constant during one revolution of the motor by phase-modulated F, G. CONSTITUTION:A partly notched multipolar magnet 1 which is secured to the same shaft 4 as a rotor 5 of a motor and rotated has portions alternately magnetized at different poles S, N and entirely nonmagnetized portions 2', and is constructed to be readily phase-modulated. A coil pattern 3 opposed to the magnet 1 is inclined with respect to the magnet 1 at the prescribed angle. When the pulses of F, G between the rotating angles 0-180 deg. are densely formed, a control system acts to reduce the rotating speed of 1a motor to operate in the direction for reducing the variation in the rotation.

Abstract: PURPOSE:To make it possible to obtain highly reliable recording position accuracy under a low cost configuration by providing the movement area of a carriage in a main scan direction on a most significant recording medium mounted on a recording medium storage part and allowing data to be recorded in the most significant recording medium using an ink jet recording head. CONSTITUTION:A recording medium mounted on recording medium storage part 9 is pressed against in the storage part 9 by its own weight. Therefore, the tip side of the recording medium in a transport direction is aligned to the storage part 9. The movement area of an ink jet recording head 1 in a main scan direction using a carriage 2 is so arranged that said area can be directly recorded in a most significant recording medium mounted on the recording medium storage part 9. Thus the recording medium is aligned to the recording medium storage part to enable data to be directly recorded in the mounted recording medium, making the best use of an ink jet recording method. Consequently, the positional inaccuracy of the recording medium resulting from the skew transport of a recording medium and defective heading does not occur, and satisfactory recording results are obtained.

Title: Picture transmitter receiver
Inventor: TAGUCHI TOMISHIGE
IPC: H04N7/00
Filed: 1988-06-02
Abstract: PURPOSE:To decrease redundancy at the time of transmitting a picture and to improve transmission efficiency by changing a reference clock frequency according to a video signal band. CONSTITUTION:A trap filter 54 of a picture transmitting and receiving device traps a frequency f1 of the sink chip of an ordinary picture quality format, outputs none when the format is the ordinary picture quality format, and outputs when the format is a high picture quality format. A detecting circuit 56 detects the existence of the output of the filter 54 and impresses the detected result to a CPU 30. The CPU 30 designates clock generating circuit 58 and 60 to be selected by a switch 66 according to the detected result. In a receiving system, a CPU 76 discriminates whether the picture quality is ordinary picture quality or high picture quality from data within a transmission range to be sent before picture data and selects corresponding clock generating circuits 88 and 90 with a switch 92. Thus, an unnecessary data part is never transmitted even when an image band is narrow, and the transmission efficiency can be heightened.

IPC: G11B5/73
Filed: 1978-11-02
Abstract: PURPOSE: To obtain a non-expanding and contracting smooth magnetic medium of a large hardness by extending a sheet of air-foamed polypropylene, etc., and laminating sheets so that the extending direction may be orthogonal mutually and forming a magnetic coating layer on these sheets through a specific coating layer.  
     CONSTITUTION: A sheet of air-foamed polypropylene, etc., is extended in one direction, and sheets where foams are extended into an oval are laminated in three layers so that extending directions may be orthogonal mutually, for example, foams 17 and 16 of sheets 5 and 7 may be in the extending direction and foam 12 of sheet 6 may be have an extending direction orthogonal to foams 17 and 16. Coating layer 4 with one smooth face is formed on this three-layer carrier so that concave 8 in the polypropylene layer 5 side may be anchored with convex part 19 of layer 4, and magnetic layer 3 is provided on layer 4. Thus, the carrier increases its hardness and has a non-expansion and contraction property because foams 17, 12 and 16 are orthogonal to one another, so that a magnetic medium of good characteristic such as S/N ratio can be obtained.
