Title: Premixture type gas burner
Inventor: EGUCHI SHINJI
IPC: F23D14/02
Filed: 1983-03-18
Abstract: PURPOSE:To provide a burner which performs excellent combustion even if the type of gas is varied, by a method wherein grooves, running in a direction extending at right angles to the continuous direction of a burner port, are provided in a brim part at the end part of a member by which the burner port and a secondary air port are partitioned from each other. CONSTITUTION:Grooves 10 are provided in a brim part 1a of a mixture gas passage member 1, and the depth thereof is greater than the thickness of the brim part 1a. The mixture gas passage member 1 is of an extrusion-molded product of aluminium, and the grooves 10 are formed by cutting. This causes mixture gas to flow out from the grooves 10 also to form small flames (f). Further, vortexes (c) and (d) are produced on the downstream side of the groove 10. This causes a flame F to be fixed to a base part, provides stable combustion, and permits prevention of creating lifting and noise.

Title: Dc elimination circuit for d/a conversion output
Inventor: HATTORI TAKAHIKO
IPC: H03M1/10
Filed: 1987-02-27
Abstract: PURPOSE:To prevent the deterioration in high frequency characteristic of an audio signal effectively by realizing a negative feedback loop of a DC component by a digital circuit. CONSTITUTION:The DC component included in an analog output of an output terminal OUT is extracted by an analog low-pass filter 21, converted into a digital DC component by an A/D converter 24 and fed back negatively to a subtraction input terminal of a subtractor 26 via a resampling circuit 25. A digital audio signal whose DC component is eliminated is outputted from the subtractor 26 as the digital DC component fed back negatively is subtracted, supplied to a D/A converter 11 and converted into a corresponding analog audio signal. Thus, even when the high frequency distortion component is generated in the capacitor in the analog low-pass filter, it is smoothed by rounding resulting from quantization at the time of A/D conversion and not fed back.

Title: Treatment of wood with resin
Inventor: ITO TATSUO
IPC: B27K3/15
Filed: 1989-02-23
Abstract: PURPOSE:To dispense with the control of curing characteristics by improving the preservability of a resin by impregnating wood with a resin solution and subsequently impregnating this resin impregnated wood with a curing agent. CONSTITUTION:For example, wood veneer (Japanese oak veneer, thickness 0.5mm) is impregnated with a melamine resin of 20% concn. by a vacuum and pressing method. Next, this wood veneer subjected to resin treatment is dried in air overnight and subsequently immersed in a 0.5% aqueous solution of an acid catalyst (phosphate type or sulfonate type) for 1-2hr and dried at 100-120 deg.C in a dryer to be cured. By this method, since it is unnecessary to mix a resin solution and curing agent before the impregnation of wood, the preservability of the resin becomes good and the curing of the resin in a storage tank is eliminated. In this case, as the acid catalyst, a 1.0% aqueous ammonium chloride solution or a 5% aqueous ferric chloride solution may be used.

Title: Cooling method of oxide superconductor
Inventor: OGAWA SHOICHI
IPC: H01L39/04
Filed: 1990-02-27
Abstract: PURPOSE:To eliminate the need for a cryogenic refrigerator and a pressure vessel by using a refrigerant, which is brought to the state of a solid at approximately 10K and to the state of a liquid at approximately 300K, as a refrigerant for cooling an oxide group superconductor. CONSTITUTION:Since a refrigerant vessel 14 is kept at 10K under the state of normal operation, water 15 as a refrigerant is brought into ice, i.e., solid state. The thermal conductivity of water under solid state, i.e., ice, is improved, and a superconducting coil 11 is cooled efficiently. Ice melts and is changed into water by a temperature rise in a device when heat penetrates from the outside or when a quenching phenomenon is volumetric generated, but no pressure rise as a gas is generated because of the comparatively small coefficient of volumetric expansion of water. Accordingly, a thick firm pressure vessel need not be used and a normal vessel may be employed as the refrigerant vessel 14, a special refrigerator for recondensation need not also be used as a refrigerator 20, and cold heads 21, 22 at 10K and 80K can be utilized as cooling sources as they are.
