Title: Magnetic shield
Inventor: SUZUKI SHOHEI
IPC: H05K9/00
Filed: 1987-08-14
Abstract: PURPOSE:To obtain arbitrariness in shape, by changing the crystal structure of a part of a shield material, and providing a non-superconductive part. CONSTITUTION:The crystal structure of a part 1A of an oxide superconductor 1, which is hard to be machined, is changed, and the superconductive characteristic at the part 1A is lost. Namely, a magnetic shield 1 comprising an oxide superconductor is machined in a disk shape. A groove, in which a coil 2 is accommodated, is formed. Before the accommodation of the coil 2, oxygen atoms are implanted in the part of the inner region 1A of the magnetic shield 1 by an ion implantation method. A laminar perovskite structure indicating superconductivity is changed, and an insulator layer is formed. Under this state, the coil is inputted. Then, an effective magnetic field is generated at the upper part. A magnetic field is not generated at the lower part because of the shield. Thus, the effective magnetic shield can be obtained.

Title: Production of patterned thin metallic sheet
Inventor: HIRUTA TOSHIKI
IPC: B21B1/28
Filed: 1985-09-13
Abstract: PURPOSE:To permit the stable rolling and transfer of a sharp pattern to an extremely thin metallic sheet in a titled method for winding a metallic sheet to >=2 pieces of driving rolls having the circumferential speeds different from each other and rolling the same by forming the pattern on the surface of the outlet side driving roll. CONSTITUTION:A rolling mill 11 of a rolling installation 10 has contact rolls 15, 16 as a driving roll. Metallic foil 18 to be un-wound is successively wound on the respective circumferential surfaces of the roll 15, a floating roll 17 and the roll 16 and is then coiled via a skin pass rolling mill 12. The rolling mill 11 drives the rolls 15, 16 in the same direction at the circumferential speed of the former lower than the circumferential speed of the latter so as to exert the inlet and outlet side tension to the foil 18 and to advance the foil 18 in an arrow direction, thereby rolling the foil 18 in the gap between each of the rolls 15, 16 and the roll 17. The rugged pattern or a pattern 16A with the difference in luster is applied on the surface of the roll 16 in this stage. The pattern 16A is thereby rolled and transferred onto the surface of the foil 18.

Title: Heating/cooking utensil
Inventor: KANEKO FUMINORI
IPC: F24C7/02
Filed: 1990-07-30
Abstract: PURPOSE:To mark a suitable scorched color on a food even when the surrounding brightness may change by allowing a monitor window to have specified light shading properties to visible light from the outside in a heating/cooking utensil which controls a heating means based on the illumination intensity of visible light reflected on a heated substance. CONSTITUTION:There are installed on a sailing 2 of a heating chamber 1a room lamp 6 which illuminates a heating chamber 1 with visible light and a light receiving device 7 which detects the illumination intensity of visible light from the room lamp 6 reflected on the surface of a heated substance 4. The light receiving device 7 is supported with a pipe-shaped support member so that it may receive only reflected visible light. Most of the visible light which has entered a door glass 13 from the outside of a heating/cooking utensil is absorbed by the glass 13 or reflected. Passing through an opening 12, it is reflected on the surface of food 4 and the light directed at the light receiving device is negligibly weak. It is, therefore, possible to minimize the effect of the outside visible light and properly judge how the food is scorched, thereby preventing excessive scorching or lack of heating.

Abstract: PURPOSE:To calculate thermal resistance by impressing and removing a DC bias voltage and a large-signal input voltage of high frequency to an FET to be measured synchronously, measuring a gate barrier potential right after the impression is released, and knowing internal temperature in large-signal operation. CONSTITUTION:A signal of 4GHz from an oscillator 1 is switched by a variable attenuator 2 with pulses from a pulse generator 14 and a signal which turns on for a time T and off for a time 99T is applied to the gate of an FET10. The changeover switch 17 for the gate 10, on the other hand, is connected to a gate DC bias power source 18 for the time T of the signal impression to apply a pulse voltage for biasing which is amplified by a driver 15 to the drain of the FET10. Therefore, the temperature of the FET10 rises in the continuation time T of the signal impression and when the voltage impression ends, the switch 17 is changed over to a constant current source 11, so that the potential at a gate terminal (b) becomes a potential vgs lower than vgo in normal operation. The thermal resistance Rth in large signal operation is known from said value.
