Title: Method and device for driving objective lens
Inventor: AIKAWA TAKENORI
IPC: G11B7/085
Filed: 1988-12-28
Abstract: PURPOSE:To execute the access control at a high speed by fixing an oscillating member to a unit body so that it cannot be oscillated in the tracking direction and fixing magnetically an objective lens holding body to the oscillating member at the time of high speed track access. CONSTITUTION:An objective lens holding body 11 is freely oscillatable in the tracking direction T against an oscillating member 31, and on the other hand, the oscillating member 31 is freely oscillatable in the focus direction F against a unit body 29, but cannot oscillate in the tracking direction T. At the time of a high speed tracking access, by allowing magnetic force to work between the oscillating member 31 and the objective lens holding body 11 supported by this oscillating member 31, they are locked. Accordingly, even if the objective lens holding body 11 together with the unit body 29 moves at a high speed, the objective lens holding body 11 comes not to oscillate in the tracking T direction by its acceleration. In such a way, at the time of a high speed track access, the objective lens holding body can be locked, and the access control can be executed at a high speed.

Title: Display device
Inventor: SHINTANI PIITAA
IPC: H04N9/29
Filed: 1994-12-15
Abstract: PURPOSE: To eliminate ineffective demagnetizing operation and to demagnetize a CRT in proper timing by placing a demagnetizing circuit in operation only when the CRT is magnetized. CONSTITUTION: When the power source is turned ON through an operation part 12, the count value (n) of a counter 13 is increased by one and set in a RAM 11. The value is compared with a constant (m) previously stored in the RAM 11 corresponding to the frequency of power-ON operation and when (n)<(m), the demagnetizing circuit is not put in operation, so that the current operation is carried on until (n)>=(m). When (n)>=(m), a CPU 10 turns ON a demagnetization switch SW to supply AC power from the power source part 2 to the demagnetizing circuit, the resistance increases at the same time due to a rise in the temperature of a posistor P, a demagnetizing current flowing to a demagnetizing coil 8 attenuates and reaches 0 level several minutes later, and then the demagnetizing operation is completed.  Thus, when the frequency of power-ON operation reaches the specific value, the demagnetizing operation is performed, so the frequency of demagnetization is decreased and the power consumption is reduced.

Title: Formation of insulator at cable joint
Inventor: SAITO KOTARO
IPC: H02G1/14
Filed: 1994-12-15
Abstract: PURPOSE: To form an insulator excellent in pressure resistance at a cable joint by setting a relatively low ambient pressure until an insulation block reaches a softening temperature and then increasing the ambient pressure when the insulation block is heated for the purpose of cross-linking. CONSTITUTION: An insulation block 16 is not subjected to a high ambient pressure at such temperature as the insulation block 16 is not softened sufficiently. If an air gap is present at the interface between the insulation block 16 and the insulation layer 18 of a power cable 12, 14, the air gap is shifted gradually from the interface depending on the extent of softening of the insulation block 16 and removed eventually. Even if a bubble is formed of a volatile substance or the like through decomposition of a cross-linking agent on the outer surface of the insulation block 16 located closely to a heat source, an air gap caused by the bubble can be removed surely. When the insulation block 16 reaches the softening temperature, the air gap is removed by high ambient pressure thus enhancing the pressure resistance at a cable joint.
