Patent JP-H03115845-A (JP)
Title: Dust detector
Inventor: IMAHASHI KAZUNARI
IPC: G01N21/88
Filed: 1990-03-15
Abstract: PURPOSE:To detect the dust stuck on a negative by a method wherein the sweeping of the surface of an object to be inspected in one direction is performed by moving laser beam and the sweeping thereof in the other direction is performed by moving the object to be inspected by a motor and the scattering beam from dust is optically detected. CONSTITUTION:The mounting angle of the mirror provided to a frame in a mounting angle changeable manner is reciprocally revolved within a predetermined angle and the locus of the coherent beam from a laser device is applied to a photographic negative by the reflection of the mirror to sweep the negative and the frame is moved in other direction by forwardly or reversely rotating a motor to sweep the entire surface of the negative. As a result, when dust is present on the negative, laser beam is scattered by the dust and an optical detector detects scattering beam to operate an alarm device composed of a lamp or a buzzer. By this method, the dust stuck on the negative can be detected and the preparation of a defective product due to the negative having dust stuck thereon can be prevented.

Title: Louver unit for vehicle traveling route
Inventor: HOSHI YOSHINOBU
IPC: E01F8/00
Filed: 1999-03-12
Abstract: PROBLEM TO BE SOLVED: To provide a louver unit for vehicle traveling route excellent in each function of light modulation, sound absorption, sound isolation, and ventilation, difficult to be clogged with refuse, and easy in maintenance. SOLUTION: Many sheets of vane-shaped louver members 3 are disposed on the inside of a frame member 2 at intervals in the direction of a vehicle. In this case, a louver member 3 comprising a hollow box-shaped body having many through-holes and having front and rear surfaces forming an arc or a parabolic smooth curved cross-section convex in the traveling direction of the vehicle and a sound absorbing material filled into the hollow box-shaped body is used as the louver members 3. Because the front and rear surfaces of the louver member 3 have the arc or parabolic smooth curved shape, disturbance of air flow is less in ventilation, thus providing better air permeability. In addition, because the curved surface is smooth, dust and refuse are difficult to be accumulated between the louver members 3, eliminating the need for troublesome maintenance.

Inventor: KAGAWA SEIJI
IPC: B32B27/00
Filed: 1999-03-12
Abstract: PROBLEM TO BE SOLVED: To provide a film which does not allow penetration of microbes or the like and allows permeation of a required minimum amount oxygen gas for vegetables/fruits to respire and generated steam by laminating a heat-fusible organic resin film with a specific crystallinity to an organic resin film to set the oxygen gas and steam permeable amounts at each specific level.

Numerous non-through holes 5 are perforated across the area from either of the surfaces of the laminated film 4 to the heat-fusible organic resin film 3 on the second surface side. The laminated film 4 shows 4,000-200,000 cc/m2 25 deg.C day latm oxygen gas permeable amount and 50 g/m2 40 deg.C 90% RH day or more steam permeable rate. The film 4 rapidly releases the steam generated by the respiration of vegetables/fruits to the outside and thereby prevents them from being rotted due to water droplets by packaging the vegetables/fruits with the film 4.

Abstract: PURPOSE:To obtain a combustion device, wide in the regulating range of the amount of combustion, by providing cracking catalyst on the inner wall surface of a burner head. CONSTITUTION:Cracking catalyst 4, in which nickel and calcium aluminate are carried by an alumina carrier, is provided on the inner wall surface of a burner head 1. Fuel and air, which are injected from a fuel nozzle 1 and an air discharging port 12, are premixed in a heated evaporating tube 6 and are changed into premixed gas while the premixed gas is injected from the flame hole 2 of the burner head 1 through a gas passageway 9 and forms flames on the surface of a wire net 3. The premixed gas is cracked into hydrocarbons, whose carbon number is small, by the catalyst 4 at the upstream side of a combustion part C. In this case, the temperature rise of the burner head 1 is restricted by the heat absorbing reaction of the catalyst whereby the temperature of the wire net 3 is reduced and the heat resistant property of the combustion part C is improved. Accordingly, the deformation as well as the breakage of the combustion part C may be eliminated and stabilized combustion, wide in the regulating range of the amount of combustion, may be effected.

Title: Nonpolluting treatment of poly-chlorinated biphenyl deposit
Inventor: MIYASHITA YOSHIO
IPC: A62D3/38
Filed: 1994-03-11
Abstract: PURPOSE:To thermally decompose a poly-chlorinated biphenyl(PCB) relatively easily by charging PCB deposits from which the PCB is removed into a metal refining and melting furnace and heating the deposits, then charging other raw materials, adding the PCB thereto and subjecting the mixture to thermal decomposition simultaneously with the refining. CONSTITUTION:A temp. of >=1100 deg.C and oxygen supply are required for progression of the thermal decomposition reaction of the PCB and, therefor, for example, a converter is used as the metal refining and melting furnace which is operated at this temp. and has an oxygen supply source to the inside of the furnace. Transformers and capacitors from which the PCB is removed are charged into this converter and are heated with fuel by an oxyfuel burner. The raw materials, such as molten iron, are then charged into the furnace and ordinary refining is executed. At this time, an insulating oil contg. the PCB which is previously removed from the transformers, etc., is added into the converter under refining and is subjected to thermal decomposition. The hydrochloric acid in waste gases is dissolved and absorbed into cooling water at the time of rapidly cooling the waste gases by the cooling water with a primary dust collector. Further, the cooling water is sprayed to completely absorb the hydrochloric acid in a secondary dust collector. Next, the waste water is recovered by a thickener and the hydrochloric acid is neutralized in a neutralizing tank.

Title: Production of electrogalvanized steel sheet excellent in surface appearance
Inventor: INOUE IKUYA
IPC: C25D5/26
Filed: 1995-03-27
Abstract: PURPOSE: To enable a steel sheet to correspond to a request for the quality in the appearance by previously executing sticking of Co plating to it at a specified relative flow rate. CONSTITUTION: For example, simulatively, a steel sheet applied with microflaws is used as an original sheet, and Co plating and electrogalvanizing are executed. Then, at the time of coating it with Co plating by 5 to 300mg/m<2> coating weight at >=0.5m/sec relative flow rate, the generation of inferiority in the appearance is made small. Namely, in the case of >=0.5m/sec, the generating ratio of stains in the appearance is made small. In the case of the coating weight of <5mg/m<2> , the generating ratio of inferiority in the appearance is made high, and in the case of >=5mg/m<2> , it is made small. Furthermore, even in the case of >300mg/m<2> , the effect on stains in the appearance can be maintained, but its corrosion resistance, particularly, corrosion from the edge parts becomes the cause of fear, and it is not preferable.  Thus, microstains in the appearance after electrogalvanizing caused by the original sheet can be improved.
