Abstract: PURPOSE:To weigh rice-cooking water, and to hold the airtighteness between a rice- cooking vessel and an inner lid, by a method wherein the inner lid is liftably hung from an outer lid, and an elastic body for depressing the inner lid against the rice- cooking vessel is mounted between the inner lid and the outer lid, and rotary means whereby the water in the rice-cooking vessel is centrifugally drained through a clearance between the rice-cooking vessel and the inner lid is provided. CONSTITUTION:An inner lid spring 36 for depressing an inner lid 38 against a rice- cooking vessel 27 is provided between the inner lid 38 and a radiating plate 32, and the rice-cooking vessel 27 in the state of being covered with the inner lid 38 is floated with respect to an lid 29, and the movement of a load sensor 55, which is a displacement type weighing-means 56, is absorbed by the inner lid spring 36, and rice-cooking water is weighed without opening the lid 29 of a rice-cooking part 26. The water in the rice-cooking vessel 27 is centrifugally drained through a clearance between the rice-cooking vessel 27 and the inner lid 38, against the force depressed by the inner lid spring 36. By the load of the inner lid spring 36, the inner lid 38 is airtightly depressed against the rice cooking vessel 27, and hence steam generated at the time of rice-cooking can surely be sealed with the inner lid 38.

Title: Absorption type cold and hot water apparatus
Inventor: AJISAKA MASATSUGU
IPC: F25B15/00
Filed: 1991-07-09
Abstract: PURPOSE:To reduce the dimensions and weight of the whole of the title apparatus by providing a float valve, which is actuated by an absorption liquid level in an absorber, on the way of a pipeline system for supplying an absorption liquid to the absorber. CONSTITUTION:A high-temperature and highly concentrated solution sent from a high-temperature regenerator 4 is diluted by a condensed refrigerant in an evaporator 1 and, as a result, a liquid level in an absorption liquid tank 22 positioned underneath an absorber 2 is elevated. According to the elevation of this liquid level, a float 12a of a float valve 12 is floated to fully open the valve. Consequently, the high- temperature solution is directly led to the absorption liquid tank 22 without being supplied to a solution spray 9. Therefor, there is no need for using a solution having low concentration because the solution is not sprayed to a heat transfer tube 10 of the absorber, and there is no need for expanding the capacities of a refrigerant tank 21 and absorption liquid tank 22. Thus, a heating cycle can be established regardless of the concentration of a solution at the time of heating operation, whereby a holding quantity of refrigerant can be decreased. Further, since the capacities of the refrigerant tank 21 and absorption liquid tank 22 can be made smaller, this makes it possible to reduce the dimensions and weight of a cold and hot water apparatus.

Abstract: PURPOSE:To prevent occurrence of air-void on a surface of a foamable resin sheet prepared by extrusion-molding, by providing perforated holes to the resin sheet, forming a lattice-pattern of projection-recess on one side of the surfaces and thereafter carrying out a high-frequency heat-treatment. CONSTITUTION:A great number of perforated holes 3, 3... are provided to the whole surface of a main body 2 of a sheet prepared by extrusion-molding of a mixture of a synthetic resin comprising vinyl chloride, ethylene vinyl acetate, etc. and a foaming material such as azodicarbonamide, etc. by an extruder. Besides, a lattice-pattern of projection-recess 4 is formed on one surface of the main body. The sheet 1 is cut into a required shape and size, and a high-frequency heat treatment is carried out on it. A non-conductive material having heat-resistance is used for a bottom force, and a metal having a high thermal conductivity is used for the top force. The sheet 1 is foamed at about 100-200 deg.C by impressing high-frequency electric current and the foaming-air comes upwards and pass through the perforated holes provided to the sheet 1. The lattice- pattern of projection-recess section 4 prevents the foaming air from staying at the surface of the main body 2 of the sheet.

Abstract: PURPOSE:To provide an entire stable flame of a gas burner by a method wherein flames of small flame holes corresponding to supporting claws of a gas burner to be utilized in a home-use gas cooking burner is cooperatively in contact with fames of the main flame holes. CONSTITUTION:A group 4 of main flame holes and small flame holes 3 are arranged near an outer circumferential edge of a burner cap 1. The flame holes 3 have a smaller inner circumferential sectional area 8 than that of the main flame holes 4 and flame hole sectional area is varied such a way as they have a height 9 which is equal to a sectional height of each of the main flame holes 4 at their outer circumference. A discharged amount of gas from the small flame holes 3 is restricted at the small sectional area 8 to show a less amount of gas than that of the main flame holes 4. The flame is expanded to a substantial same flame height 9 as that of the main flame hole 4, so that a length of flame is short and the flame is expanded. Accordingly, it is possible to prevent the flame from being contacted with the supporting body and from generating CO and at the same time a stable combustion can be carried out even in case that a lift gas or a gas pressure is high.

Title: Noise eliminating device
Inventor: YAMADA JUN
IPC: H04B1/10
Filed: 1984-08-10
Abstract: PURPOSE:To eliminate surely an impulse noise and to attain miniaturization and light weight of a radio equipment by using a crystal filter giving a limit of a reception band and a flag group delay time. CONSTITUTION:When a pulse noise A is applied, a pulse noise shown in a waveform B is produced at an output of a broad band noise detector 16. On the other hand, a noise like a waveform D is produced at an output of a crystal filter BPF14 giving limit of reception band and flat group delay time. A delay pulse generator 17 produces leading with a delay of a prescribed time t1 from a leading (a) of the output waveform B and trailing by t2 from this point. Since the consecutive time t2 is a time including most of the pulse output of the BPF14, the impulse noise is eliminated surely.

Filed: 1996-06-06
Abstract: PROBLEM TO BE SOLVED: To reduce the abnormal corrosion of a lead-acid battery by using lead-antimony alloy having the nickel content of the specific range wt.% for a part of an electrode plate connection section, an inter-cell connection section, and an electrode pole. SOLUTION: Nickel of 0.0002-0.003wt.% is added to a lead-antimony alloy as the alloy used for at least a part of an electrode plate connection section, an inter-cell connection section, and an electrode pole to manufacture a lead-acid battery. Test pieces are generated from this alloy, the thickness reduction ratio of a base material is investigated at a positive electrode corrosion generation portion and a negative electrode corrosion generation portion after corrosion tests are completed. The thickness reduction ratio is hardly changed on the positive electrode side even when the Ni quantity is changed, however the thickness reduction ratio is abruptly decreased on the negative electrode side when the Ni quantity is set to 0.0002wt.% or above.  Ni serves as a catalyst for oxygen reduction to reduce the oxygen reduction corrosion of lead, and Ni is dispersed in lead to form a hardly corroded alloy structure.

IPC: H01L23/50
Filed: 1987-07-08
Abstract: PURPOSE:To reduce noises at the time of cutting by turning a cutting die and gradually cutting a section to be cut several times when a lead frame is out. CONSTITUTION:A top force 9 and a bottom force 14 are synchronized in a cutting die 8, and conduct a rotary motion.

Only the noses of the leads 5 are cut gradually by the revolution of the cutting die 8 at that time, thus lowering sounds generated at the time of cutting. The damage of the cutting teeth can be reduced.
