Title: Illumination device
Inventor: EDOWAADO ARAN SUNAIDAA
IPC: F21V7/08
Filed: 1993-08-17
Abstract: PURPOSE: To direct light from a light source to a desired pattern by deformed ellipsoids, and to disperse light in a desired pattern and to facilitate manufacture, by forming a junction between a center-deformed ellipsoid and edge- deformed ellipsoids. CONSTITUTION: The reflective surface of a reflector 13 includes a center- deformed ellipsoid 14 and two edge-deformed ellipsoids 15, 16. The face 15 is joined to the center face 14 in a smooth continuous junction 17, and the face 16 is similarly joined to the face 14 in a smooth continuous junction 18. The face 14 is modified to include a smooth vertical bump 21 on the center of the ellipsoid and has a concave shape, and is tilted off the axis of a headlight. And besides, the faces 15, 16 are also concave faces, and are deformed from a true paraboloid, to generate a prescribed optical pattern and to make the junctions between the faces smooth and continuous. The junctions 17, 18 have clear normals and minimum radii of curvature larger than about 1.27 mm, and a flute is not formed on a front cover.  Hereby, light can be dispersed in a desired pattern, and manufacture can be facilitated.

Filed: 1992-07-08
Abstract: PURPOSE:To obtain a method for inspecting defect of a web in which a defective cup is automatically prevented from being transferred to following process when the cup is formed from the web. CONSTITUTION:An image line sensor 14b is disposed on the inlet side of a cupping machine 8 whereas a conveyor 11 equipped with normal sucking sections 11a, 11c for carrying a cup 10 while suspending through suction and an ON, OFF sucking section 11b is disposed on the outlet side.

Upon detection of the first mark 3, the machine 8 is stopped temporarily based on a detection signal before a web part corresponding to the first mark passes through the cupping machine 8. Upon detection of the second mark 4, the ON, OFF sucking section 11b is turned OFF based on a detection signal when the cup 10 formed of a web part corresponding to the second mark 4 arrives at the ON, OFF sucking section 11b thus dropping the cup 10 from the conveyor 11.

Title: Surface defect inspection instrument
Inventor: FUSHIMI KIMIHISA
IPC: G01N21/94
Filed: 1988-08-17
Abstract: PURPOSE:To improve the identifying ability for the size of a defect by using two lasers which differ in wavelength as the light source of a detection system, and performing detection by the other light source in an area wherein it is difficult to perform discrimination by one light source, and making them complement each other. CONSTITUTION:A carbon dioxide gas (CO2) laser 11 is provided as a 2nd light source in addition to an He-Ne laser 1 as a 1st light source. Further, two kinds of photodetectors are provided corresponding to the light sources, a photoelectron multiplier tube 6 is used for He-Ne laser light, and a PbS photodetector 13 is used for CO2 laser light. Then an Si wafer 3 to be inspected is irradiated by the respective diameters of the light sources. If there is a defect on the wafer 3, the laser light beams are scattered and entered into the detectors 6 and 13. The scattered light beams entered into the detectors 6 and 13 are converted into electric signals, which are sent to a signal processing system 15 to detect the size and position of the defect. Thus, the two light sources which differ in wavelength are used as the same time, so variation in scatter sectional area becomes larger by at least one light source in the entire range at all time for the defect diameter, and the defect diameter is accurately recognized.

Title: Refining method of cerium acetate
Inventor: AKAZAWA NOBUAKI
IPC: C01F17/00
Filed: 1990-08-01
Abstract: PURPOSE:To refine cerium acetate into high purity cerium acetate containing no undissolved matter at a low cost by dissolving cerium acetate at specified temp. and specified concn. and heating the obtd. soln. to specified temp. to precipitate cerium acetate. CONSTITUTION:First, an aq. acetic acid of about 20-25wt.% concn. is prepared by diluting about 3-4mol of glacial acetic acid to 1mol of cerium carbonate. This acetic acid soln. is heated at about 50-90 deg.C and stirred, to which cerium carbonate is slowly added and dissolved. Refining is carried out since cerium acetate contains impurities such as cerium oxide, etc., originally present in the source cerium carbonate, or basic cerium acetate as the byproduct of this reaction. The solubility curve of cerium acetate to water shows a V shape with the minimum at 70 deg.C. Therefore, the soln. prepared by dissolving at <=35 deg.C to the saturation or near the saturation concn. of >170g/l (0.54mol/l) is heated at 50-90 deg.C to precipitate cerium acetate. Then this precipitate is separated by filtering and dried to obtain the object cerium acetate.

IPC: F28F1/32
Filed: 1989-08-07
Abstract: PURPOSE:To improve a heat efficiency by so providing deflectors as to accelerate the flowing speed of fluid at the contact part of the fluid with a tube and to reduce a boundary layer in the fluid, and so arranging the deflectors in a truncated chevron shape as to narrow its width in the advancing direction of the fluid. CONSTITUTION:Deflectors (110, 210, 310,...) are so provided as to narrow its width distance along the flow of fluid to the surface in contact with a tube with respect to a fluid flowing direction. The flow of the fluid is accelerated in its speed at a position out of the deflectors by the deflectors composed in the truncated chevron shape by means of its contracting effect to be brought into contact with the tube. Accordingly, the contact fluid amount with the tube is increased, heat exchanging amount is increased, and the thickness of a boundary layer is reduced, and its heat transfer efficiency is improved. A small gap is provided between the adjacent deflectors formed in the truncated chevron shape on the inlet side of the truncated chevron shaped deflectors. Thus, since the flows 412,... sufficiently flow along the tube, a stagnation layer can be reduced.
