Title: Magneto-optical recording medium
Inventor: TAKATSUKA YUJI
IPC: G11B11/10
Filed: 1993-04-14
Abstract: PURPOSE:To provide the magneto-optical recording medium having excellent rewriting resistance by preventing the thermal deterioration of a transparent substrate at the time of rewriting. CONSTITUTION:The main part of the magneto-optical recording medium is constituted of the transparent substrate 10 which is made of polycarbonate, a first dielectric interference layer 21 (AlN) of a low theramal conductivity and a second dielectric interference layer 22 (TaOx) of a high thermal conductivity which are successively formed on this transparent substrate, a memory layer 31, intermediate layer 32 and writing layer 33 which are successively formed on this second dielectric interference layer and constitute a magneto-optical recording layer and a dielectric protective layer (TaOx) 40 which is formed in this writing layer 33. The flow of heat to the transparent substrate side is lessened by the effect of the second dielectric interference layer 22 of the low thermal conductivity and the output of a laser power is decreased by decreasing the heat radiatror from the magneto-optical recording film. On the other hand, the heat from the magneto-optical recording film flowing out into the first dielectric interference layer via the second dielectric interference layer is widely diffused by the effect of the first dielectric interference layer 21 of the high thermal conductivity and, therefore, the thermal influence on the transparent substrate is lessened.

Title: Display device for plural patterns in video equipment
IPC: H04N5/45
Filed: 1992-03-11
Abstract: PURPOSE:To observe simultaneously a master pattern and a slave pattern overlapped with each other by thinning scanning lines of the slave pattern at a prescribed rate and inserting a signal of the master pattern to the thinned scanning lines.

Title: Duplex power supply system
Inventor: YANO YASUSHI
IPC: H02J1/12
Filed: 1995-04-13
Abstract: PURPOSE: To increase the degree of freedom in the arrangement and connection of power supply package while reducing the size of duplex power supply by duplicating the power supply package and feeding power to a load from the power supply package having higher output voltage. CONSTITUTION: When power is fed from an input power supply 1, duplicated power supply packages PWR0, PWR1 normally begin operation to feed a load 14 with power. Since the error voltage detection terminals Td11, Td12 of the power supply package PWR1 are connected with the duplicated control terminals Tc01, Tc02 of the power supply packages PWR0 and the error detection resistor 11 of the power supply package PWR1 is short-circuited, output voltage from the DC/DC converter CON1 of the power supply package PWR1 becomes lower than the output voltage from the DC/DC converter CON0 of the power supply package PWR0. Consequently, the load is fed with power from 1 the power supply package PWR0 having higher output voltage.

Title: Portable type shaft part working machine
Inventor: YOSHINAGA FUMIO
IPC: B23B3/26
Filed: 1984-05-04
Abstract: PURPOSE:To aim at the retrenchment of machining expenses, by setting a portable type working machine to a work piece shaft part as leaving a workpiece shaft clamped intact, and working the workpiece shaft part. CONSTITUTION:A setting flange 1 is clamped upon centering with a workpiece shaft 13 as the center. Then, when a motor 5 is driven, power is transmitted to an internal gear 7 from a pinion shaft 6. With this power transmission, a turning ring 4 comes into rotation, making a cutting tool 8 rotate around the circumference of the workpiece shaft which is therefore machined. At this time, a depth of cut is given by operation of an infeed handle 9 and, what is more, the feed required is as well given when a feed handle 11 is rotated, thus necessary machining for the workpiece shaft 13 takes place. Accordingly, it is unnecessary to disassemble and carry out the shaft so that the time required for machining is well shortened.

Title: Semiconductor device
Inventor: TAKAO HIROSHI
IPC: H01L23/42
Filed: 1978-07-21
Abstract: PURPOSE: To improve heat radiation by providing a thin hollow layer in a substrate and by charging a refrigerant.  
     CONSTITUTION: A thin hollow layer 3 is provided in a substrate 2 to which a pellet 1 is fixed. To this hollow layer, a refrigerant such as distilled water, ammonia, alcohol, or Freon is charged under a reduced pressure of 10 -1  to 10 -3 mmHg for instance. Heat produced in the pellet 1 is directly conducted down to the substrate 2, and evaporates the refrigerant 4 in the hollow layer 3. The evaporated refrigerant 4 is liquified by releasing the latent heat at a low temperature section in the periphery of the substrate, and is recycled again to the center of the substrate 1 by means of the capillarity action of the hollow section 3. By so doing, heat generated in the pellet is radiated very effectively to the periphery of the substrate by means of the heat-pipe principle.
