Title: Cleaning card
Inventor: NAKAMURA SHINJI
IPC: G11B5/41
Filed: 1995-04-17
Abstract: PURPOSE: To obtain an excellent cleaning card against contamination with dust or oily contamination by forming a resin layer having a microporous structure on the inside and the surface of a paper, cloth or nonwoven fabric and forming an abrasive grain layer of a desired shape on the surface of the resin layer. CONSTITUTION: This cleaning card is produced by impregnating a paper, cloth or nonwoven fabric 1 with a resin so that the inner structure and the surface of the above material 1 is coated with a resin layer 2 having a microporous structure, and thereby, fluffing from the cloth or nonwoven fabric 1, dropping of fiber or occurrence of powdery fiber from a cutting part can be prevented. Since the resin layer 2 has a continuous microporous structure, the obtd. card can absorb and hold a detergent such as alcohols and well clean off oily contamination and the like. As for the elastomers used for the resin layer 2, polyurethane, polyester or the like can be used and an inorg. or org. filler or pigment such as silica and calcium carbonate can be added.  By binding a fine powder of aluminum oxide or silicon carbide with a proper resin to form an abrasive grain layer on the surface of the resin layer 2, contamination depositing on an apparatus can be well removed with the obtd. cleaning card.

Title: Gas range for kitchen
Inventor: FUJISAKI OSAMU
IPC: F24C15/14
Filed: 1979-09-11
Abstract: PURPOSE: To prevent burner flames from extinguishing due to boil over above a burner, by a method wherein a main gas burner, positioned in a casing of a gas range, is positioned at a place which is a little apart from a point being just under a hot air vent in a stock receive pas.  
     CONSTITUTION: A gas flows through a main nozzle 17 from a plug 15 to a main gas burner 7 with a plug knob 16 turned, and simultaneously, it flows to a pilot burner 18 via a pilot nozzle 19. The pilot burner 18 is ignited by means of a sparker 20, and thereby a burner 7 is ignited. The heat produced by said burner 7 is reflected in order on reflection plates 11 and 12 on the way in its rise through a connection path 8 to be fed to a hot air vent 4, and heats a pan 6, placed on a pan support 5, for cooking. At that time, stocks are boiled over the pan 6, and boil-over stocks flowing into a casing 1 through the vent 4 are accumulated in a stocks receiving container 13 being positioned just under the vent 4. The burner 7 can thus maintain a normal combustion condition thereof.

Title: Sodium-sulfuric battery
Inventor: KAGAWA HIROSHI
IPC: H01M10/39
Filed: 1983-06-27
Abstract: PURPOSE:To heighten the safety of a battery, by disposing a sodium reservoir on the top of a solid electrolytic tube, while installing a fully hermetically sealed metallic vessel filled up with a substance to be turned into inert gas or high temperature gas, in the lower part of the said reservoir. CONSTITUTION:A metallic vessel 15 consisting of a low-melting point metal or the like is installed inside a solid electrolytic tube 1 so as to be broken down with a direct reaction of heat between a negative pole active material 11 and a positive pole active material 6, while inside the metallic vessel 15, materials of inert gases such as nitrogen, argon, etc., and sodium azide being gasified into the inert gas at high temperature are filled up and fully sealed up. When a crack happens in the solid electrolytic tube 1, if fused sulfur and sodium directly react, the metallic vessel 15 is broken down the heat produced whereby the inert gas inside is forced out. With pressure of this discharged gas, a sodium interconnecting passage 19 is reversely pushed up from downward by the fused sodium in consequence, and therefore feed of the fused sodium from a sodium reservoir 16 comes to a stop so that continuous direct reaction never happens there.

Filed: 1988-05-13
Abstract: PURPOSE:To unify the sticking and improve the adhesive strength by radiating ultraviolet rays to at least one of sticking faces of a metal foil and a plastic film, then overlapping them via an adhesive or no adhesive, and heat-pressing them. CONSTITUTION:When ultraviolet rays with the preset wavelength are radiated to the surface of a metal foil made of lead or lead alloy or a plastic film, ozone or activated oxygen is generated from the oxygen in the air existing between the surface and the light source of ultraviolet rays, an organic contaminant stuck to the surface and obstructing the sticking can be oxidized and volatilized, the sticking face gets the activity suitable for sticking. When ultraviolet rays are radiated to at least one of the surfaces of the metal foil and the plastic film then both of them are stuck, a lead-laminated tape with uniform sticking and high adhesive strength can be manufactured. The wavelength of the ultraviolet rays to be radiated is set to the range of 150-300nm.

Abstract: PURPOSE:To obtain a copied image of high resolution, by moving an original in the direction opposite to the moving direction of a photosensitive body at the time of exposure and, at the same time, setting the ratio of the moving speed of the photosensitive body to that of the original equal to the copying magnification. CONSTITUTION:Exposure is performed while both an original 5 and photosensitive body belt 12 are moved and the original 5 and belt 12 are moved in oppsite directions shown by arrows (a) and (b), respectively. The ratio of the moving speed of the belt 12 to that of the original 5 is set equal to the copying magnification and, in the case of equal magnification, the original 5 and belt 12 move in opposite directions at the same speed. An original detecting switch 15 is provided on a platen glass 1 and, when the original 5 is carried by an original carrying belt 2 and its front end reaches the position of the switch 15, sends a detect signal to a power source 11 and causes the power source 11 to generate a flash trigger pulse. When the pulse is generated, xenon flash lamps 7 and 8 discharge and the energy accumulated in a capacitor inside the power source 11 is discharged. Thus lights are emitted and the copied image of the original 5 is obtained.

Abstract: PROBLEM TO BE SOLVED: To measure the absorption spectrum of a trace amount of isotope molecule present in a numerous natural molecules with precision. SOLUTION: A monochrome light is taken out of the light of a light source 21-1 by a monochrome meter 21-2. The light is split into two linear polarizing light fluxes whose polarizing surfaces orthogonal to each other by a beam splitter 23-1. One of them is allowed to transmit a reference cell 26-1 while the other allowed to transmit a sample cell 26-2. The two light fluxes which have transmitted the cell are superposed together with a polarizing prism, and among the light fluxes, the light of such polarizing surface as 45 deg. against each polarizing surface of two light fluxes superposed together is taken out with a polarizing plate 27, for measurement of its intensity. Thus, by utilizing the interference of light, differential amount in absorption of two cells is measured with precision.

Abstract: PURPOSE:To suppress the disturbance caused by a disturbing radio wave by changing a pseudo noise for transmission modulation and reception modulation into another pseudo noise when a disturbing radio wave which is modulated with the same pseudo noise code as that used for spectrum spread modulation during transmission is received. CONSTITUTION:When a disturbance is caused by a radio wave which is modulated with a pseudo noise PRG used for a spectrum spread radar, the radio wave is received by a spectrum spread radar receiver and processed without being discriminated from an original transmit signal reflected wave, so that the disturbing radio wave is misrecognized as the transmit signal reflected wave.
