Title: Shifting device of magnetic tape
Inventor: TANI TOYOFUMI
IPC: G11B15/32
Filed: 1980-09-05
Abstract: PURPOSE:To reduce not only the rise time of the tape travel but the power consumption of a motor, by setting the diameter of a reel hub at a value by which the maximum equivalent moment of inertia of a driving device becomes minimum. CONSTITUTION:Reels 2 and 4 are turned by motors 3 and 5 respectively, and a magnetic tape 1 is taken up between these reels. Then the diameter of a reel hub is set at a value by which the maximum equivalent moment becomes minimum for a driving device consisting of the motors 3 and 5. This minimum value can be obtained in accordance with the motor or the magnetic tape which is used. In such way of deciding the hub diameter of the reel, the rise time can be reduced for the travelling of the tape 1. At the same time, the necessary torque of a motor is reduced to reduce the power consumption.

Title: Method and device for modulating laser power for recording
Inventor: AOKI GIICHI
IPC: G11B7/00
Filed: 1989-05-19
Abstract: PURPOSE:To set a recording bit to a suitable length by shortening a time from the rise to the fall of a laser emitting waveform to a suitable length. CONSTITUTION:Power modulating operation is executed to strengthen laser power rather than normal power in fixed section just after the rise and just before the fall of a recorded signal (g). Before this power modulating operation, waveform shortening operation is executed to shorten the continuing time of the recorded signal (g) to the time from the rise to the fall, namely, to shorten the time length of an waveform at a high level to emit a semiconductor laser. Accordingly, after the power modulating operation, the output waveform can be shortened to a suitable length. Thus, a recording bit P can be set to the correct length.

IPC: B28B1/00
Filed: 1987-05-21
Abstract: PURPOSE:To secure such an oxide superconducting wire that is excellent in characteristics by compressing powder for a material containing an oxide superconductor or its constituent elements, producing a bar compact and covering a nonoxidizing metal layer, and gethering a lot of these compacts, covering each with a yet harder secondary metallic layer, and adding heat treatment to it after wire drawing. CONSTITUTION:Mixed powder of an alkaline earth metal, a III (a) group element and copper oxide is mixed at the specified ratio and, after calcination, it is pressed into a bar form. A compact 1 is subjected to heat treatment in an oxygen stream and formed into, for example, a stratified perovskite type oxide superconductor as a whole. Next, it is covered with a nonoxidizing metallic layer 1a of Ag or the like producing an aggregate 2 of many pieces, and it is covered with an antirust steel pipe 6, setting this down to a complex 4. And its diameter is contracted, thus it is formed into a wire rod 5. A stabilizing pipe 7 of Cu or the like is covered on this antirust steel pipe 6 and wire drawing takes place, setting it to the desired wire diameter, thus an oxide superconducting wire 8 is produced after heat treatment. The nonoxidizing metallic layer 1a prevent oxygen in a superconducting fine wire from being absorbed by an oxidizing metal, and thereby a superconducting characteristic good in the fine wire is maintained in a conductor as it is, so that it is usable for a cable.

Title: Deflecting device for cathode-ray tube
Inventor: SONEDA KOICHI
IPC: H01J29/76
Filed: 1990-05-15
Abstract: PURPOSE:To solve problems regarding withstand voltage by dividing each of two deflecting coils using a middle extension wire into two coil portions one located in front of and the other behind the middle extension wire when seen from the direction in which to start winding each coil, while varying the ratio of the inductance of the two coil portions to each other from one deflecting coil to the other. CONSTITUTION:One deflecting coil 20B is wound in the direction opposite to that in which the other deflecting coil 20A is wound and the deflecting coils 20A, 20B are disposed opposite each other so that the inductance of a winding- finishing side coil portion 22c located in front of a middle extension wire 21b when seen from the direction in which to start winding each coil is Lm, while the inductance of a winding-start side coil portion 22d located behind the middle extension wire 21b is Ln. The coils can therefore be connected to each other without bringing the high-voltage side portion of one coil located on current supply side into contact with the low-voltage side portion of the other coil where voltage is dropped by the inductance of the coil. The problem of withstand voltage is thus solvent.
