Title: Heat cooking device
Inventor: TOMIBAYASHI TATSUMI
IPC: A47J37/06
Filed: 1993-09-30
Abstract: PURPOSE:To suppress a sticking of food by virtue of radiation heat and a direct heating and make fine burning marks and improve the result by forming a cooking plate with a molding having finely uneven surface which employs Nanbu iron and providing uneven parts on a cooking surface. CONSTITUTION:The rear surface of a cooking plate 32 is flattened to improve a heat transfer efficiency from an electric heater. Protruding parts 36a formed on a front surface cut into a piece of meat M and parts in which they abut against protruding parts 36a of the piece of meat M are directly heated. A remaining meat surface is steam-roated by virtue of radiation heat from recessed parts 36b, so that the evaporation of water and the discharge of meat juice are controlled. On the surface of the piece of meat M, linear burning marks are formed. An excessive oil is stored in the recessed parts 36b and does not stick again to the surface of a cooked food. Since the protruding parts 36a in contact with the cooked food are small in terms of area, a residue in a preceding cooking does not stick again thereto. Since the cooking plate 32 has a fine surface with fine uneven parts, the oil penetrates into the uneven parts, so that the sticking of food can be prevented and fine burning marks can be formed on the food.

IPC: G11B5/52
Filed: 1986-10-16
Abstract: PURPOSE:To improve the workability of assembling by providing the inserting port of a jig to press fit a first outer ring at a flange and press fitting in the first outer ring into a fixed drum while the flange is fixed to a rotary shaft beforehand. CONSTITUTION:By matching at a flange 6 in the shaft direction to the first outer ring 501 and by a pitch of about 120 deg. in the circumferential direction, a hole 601 in the shaft direction is formed. The hole 601 functions as a jig inserting port to insert the jig to press fit the first outer ring 501 into a housing part 101 of a fixing drum 1. The flange 6, after the outer ring 501 is press fitted into the fixing drum 1, is not bonded and fixed to a rotary shaft 4, and bonded and fixed at the rotary shaft 4 while the height is regulated beforehand. In order to fix the unit to the fixing drum 1, a press fit jig is inserted into the hole 601 of the flange 6, the outer ring 501 may be press fitted into the housing part 101 of the fixing drum 1 and a second outer ring 502 is bonded to the housing part 101 in the same way as the conventional operation. Thus, since the flange 6 is fixed at the rotary shaft 4 while the height is regulated beforehand, the height regulation is not necessary at the time of assembling, and the workability is improved.

Title: Lead wire connecting device for superconducting equipment
Inventor: WADA TSUKASA
IPC: H01R13/62
Filed: 1987-09-30
Abstract: PURPOSE:To make a device small-sized and reduce the cost by controlling the pressure in bellows from the outside to expand and shrink the bellows and selectively connecting movable multi-pin connectors to fixed multi-pin connectors. CONSTITUTION:The pressure in bellows 42 and 43 is controlled to expand or shrink the bellows 42 and 43, thereby movable multi-pin connectors 36 and 37 are selectively connected to fixed multi-pin connectors 31 and 32. In this case, all lead wires 44, 45 and 47-52 are located in the recovery passage of the He gas, thus the lead wires are cooled by the low-temperature He gas. When the connectors 31, 32, 36 and 37 are in a connection state, the heat quantity infiltrating through the lead wires can be suppressed to a small value. Since a refrigerant guide pipe 24 is cooled, the heat infiltration through the guide pipe 24 can be suppressed to a slight value. The connector mechanical can be integrated even if there are many lead wires according to this constitution, thus the device can be made compact, and the cost can be reduced.

Title: Video signal recording circuit
Inventor: HONDA KAZUHIKO
IPC: H04N5/92
Filed: 1984-11-22
Abstract: PURPOSE:To eliminate an interruption against a regeneration signal of a character multiplexing signal by attenuating a part corresponding to the sound FM signal insertion frequency band of a recording video signal, and by attenuating the other part corresponding to the second FM signal insertion frequency band by a trap having a small attenuation amount. CONSTITUTION:In regard to the part where the character multiplexing signal is superposed among video signals, since the character multiplexing signal is completely removed from the sound FM signal insertion frequency band by a hard trap 12, the SN of regeneration sound signal in that part is improved, and the high quality of a regenerated sound can be obtained. On the other hand, since the part of the video signal attenuates the sound FM signal insertion frequency band so that the parts of a brightness signal and chrominance components are hardly eroded, the reduction of the resolution of the regenerated screen and the oozing of color in the edge part are prevented and the deterioration of the quality of the regenerated picture is prevented. Thus, the high quality of the regenerated sound signal can be realized by the elimination of the interruption of the character multiplexing signal against the sound signal without harming the quality of the regenerated screen.
