Abstract: PURPOSE:To carry out rice cocking with uniform heating by arranging the constitution such that the bottom of an inner container body and the inside of the bottom of an outer container are stuck fast to each other, and that heat-resistant and heat-conductive solution is filled up in the blocked space made between the side faces. CONSTITUTION:A heating means 2 is installed at the bottom of an outer pot 1, and an inner pot 4 is accommodated inside so as to be coupled thermally or magnetically with the heating means 2, and a cover 3 is provided at the top, and the inner pot 4 is composed of an inner container 5 and an outer container 6. The bottoms of both containers are welded together, and space is left between both side faces, and the brims of top openings are welded in a body to form blocked space 7. Heat-resistant and heat-conductive liquid 8 is filled up in the blocked space 7. Hereby, not only the heat can be conducted into the inner container 5 by heat conduction from the bottom of the inner pot 4, but also the heat of the bottom of the outer container 6 can be conducted to inside from the side of the inner container 5 by action of conduction and convection of the heat-resistant and heat-conductive liquid 8 sealed in a closed space 7, so equal rice cooking can be made by the so-called walnut effect.

Title: Semiconductor relay circuit
Inventor: ARAKAWA MASAO
IPC: H03K17/78
Filed: 1986-01-25
Abstract: PURPOSE:To realize a semiconductor relay circuit which can execute switching at a high speed, by a simple circuit constitution, by providing a controlling circuit for executing quickly charge and discharge of a control voltage of a switching element. CONSTITUTION:A P channel MOSFET 12 has an operation for discharging more completely the charge which is accumulated in a control terminal of a switching element 7, when an optical signal is cut off. That is to say, generally, a voltage drop at the time of conduction of the MOSFET is lower than a voltage drop at the time of conduction of a thyristor, therefore, a parasitic thyristor of a CMOS inverter 5 discharges to some extent the charge which is accumulated in the control terminal of the element 7, when the optical signal is cut off, and even after it is turned off naturally due to a drop of its across voltage, the FET 12 still conducts, and the charge which is remained in the control terminal of the element 7 is discharged more completely.

Title: Crosslinked-polyethylene-insulated cable
Inventor: NAKAMURA SHIYOUICHIROU
IPC: H01B3/44
Filed: 1995-01-31
Abstract: PURPOSE: To maintain low the oxygen concentration of a crosslinked- polyethylene insulator during preservation to prevent formation of water during heating by covering the crosslinkedpolyethylene insulator with a metal sheath, and providing a deoxidation layer. CONSTITUTION: A crosslinked-polyethylene insulator 3 is covered with a metal sheath 8, and a deoxidation layer 5 is provided between the insulator 3 and the metal sheath 8. This constitution allows oxygen in the metal sheath 8 to be absorbed into the deoxidation layer 5, and since oxygen outside the metal sheath 8 cannot penetrate through, oxygen in the insulator 3 inside the metal sheath 8 can be maintained at low oxygen concentration even without the cable being preserved in a lean oxygen atmosphere after manufacture. Therefore, formation of water can be prevented even in cases where the cable is heated within the atmosphere after long-range preservation. Desirably, a deoxidizer 1g of which absorbs 10ml or more oxygen is contained in the deoxidation layer 5 by 10g or more per 1m of the cable.  Also, the deoxidizer contained in the layer 5 is desirably composed chiefly of iron powders or active iron oxide powders.

Title: Level control circuit
Inventor: KIMURA KATSUMI
IPC: H04N9/793
Filed: 1983-02-02
Abstract: PURPOSE:To extract assuredly the burst signal of one side even with the variable speed reproduction by controlling the frequency characteristics so that the center frequency of a filter circuit for discrimination of burst signal is varied in response to the change of the tape speed. CONSTITUTION:For a synchronizing separator 22 of an ACC signal circuit part, a horizontal synchronizing signal SH obtained from the luminance signal Y is converted into a speed detecting signal 21 via a reproduction speed detecting circuit 31 and applied to a filter circuit 12 containing a voltage control type band pass filter with which the central frequency can be controlled. Thus an output S5 obtained by transmitting burst signals BR and BB through the circuit 12 is generated as if it held the reference level of a comparator 14 in a normal reproduction period. Thus it is possible to deliver a sampling pulse S11 through a burst gate circuit 27 every time the signal BR is supplied. The same operation is carried out also in a triple-speed reproduction and reverse reproduction modes respectively.

Title: Testing method for bending fatigue of pipe or the like
Inventor: YANAI HIROSHI
IPC: G01N3/34
Filed: 1986-01-28
Abstract: PURPOSE:To prevent a rod material side from being broken at the contact part between an end part of an outer fitting part and a rod material by reducing the bending rigidity of the fitting part of a bending jig to the rod material. CONSTITUTION:While bending jigs 2 are mounted on both end parts of the rod material 1, bending moment M is applied in the mutually counter directions from parts 2 of the jigs 2 other than their outer fitting parts 2a. Then, the moment M is transmitted to the rod material 1 to generate axial compressive stress caused by the bending at upper contact parts 1a which contact side end parts of the outer fitting parts 2a of the jigs 2 along with contact stress by the jig 2. In this case, the outer fitting parts 2a are tapered and reduced in bending rigidity, so the outer fitting parts 2a have flexible structure against the bending. The range of the contact parts 1a are limited not locally, but to constant width to reduce the contact stress and also prevent the stress from being converged owing to the formation of a cut due to the contacting. Consequently, a breakage caused by the jigs 2 is eliminated. Therefore, the side of the rod material 1 is prevented from being broken at the contact part between the end prevented from being broken at the contact part between the end part of the outer fitting part 2a and the rod material 1.
