Title: Transmission type screen
Inventor: OONO MINORU
IPC: H04N5/74
Filed: 1981-11-05
Abstract: PURPOSE:To improve the brightness of pictures markely and to prevent the reflection of unnecessary light from a front surface in a rear projection type image receiver by forming Fresnel lenses on the rear side of a screen body and forming many conical bodies on the front side. CONSTITUTION:Projecting lighg 7 for projection of pictures irradiated from the rear of a screen body 8 is bent in the direction parallel with the axis of the screen by Fresnel lenses 9, and is emitted to the front side by having directivity around the axial direction of the screen by conical bodies 10. Therefore the emission of the projecting light toward the directions of large angles from the axis on the front side of the body 8 is decreased and the brightness of the picture is increased markedly. If the conical bodies 10 having semispherical tips and light absorptive materials 11 among the clearances between the bodies 10 are provided, the reflection of the unncessary incident light from the front side is prevented and the easy-to-see pictures are projected.

Filed: 1999-06-24
Abstract: PROBLEM TO BE SOLVED: To rapidly and effectively fix an organism tissue by irradiating a sample obtained by dipping the tissue in a fixative or the like contained in a container with a microwave, and applying a pressure to the sample. SOLUTION: The apparatus for manufacturing a sample of an electron microscope comprises a microwave irradiating means for irradiating a sample 4 obtained by dipping the tissue in a fixative or the like contained in a container 3 with a microwave 20, and a pressurizing means for applying a pressure to the tissue.

Title: Liquid processor
Inventor: NOGAWA ATSUHIKO
IPC: A61M1/14
Filed: 1990-07-06
Abstract: PURPOSE:To efficiently perform gas exchange, etc., by bringing gas containing oxygen into contact with liquid via liquid processing film immediately by providing a gas room provided extending from a lower side to an upper side at the other plane side of the liquid processing film, and providing the gas inflow port of the gas room at the lower part of the gas room. CONSTITUTION:The gas exchange is performed and the oxygen is added by making the gas flow in from a blood inflow port 19 to a blood room 21 via a passage in a blood introduction tube 17, and bringing it into contact with blood processing film 7 consisting of the porous hollow thread film of a blood processing part 6 after performing debubbling by a debubbling member 13. The aperture 9 at the lower side of the blood processing film 7 comprises the gas inflow port. The gas passing through the gas room in the blood processing film 7 flows out from the aperture 9 formed at the end face of an upper partition. Meanwhile, a gas deriving port 29 communicated with a spatial part 25 is provided at a housing 3 which forms the upper spatial part 25. Thereby, the gas that flows out from the upper aperture 9, after once flowing in the upper spatial part 25, is quickly derived from the gas deriving port 29, and is diffused to the outside. A residual spatial part at the upper side other than blood in the blood room 21 is communicated with the outside at the upper part, therefore, air pressure at the part becomes equal to the atmospheric pressure.

Title: Manufacture of polyetherimide foamed sheet
Inventor: OKUDAIRA YUTAKA
IPC: C08J9/12
Filed: 1985-08-14
Abstract: PURPOSE:To manufacture a PEI foamed sheet having the uniform skin, by a method wherein nonexpanded polyether imide sheet heated at a specific temperature is quenched while atmospheric pressure is being made to deteriorate after the same has been placed under pressurized gaseous atmosphere. CONSTITUTION:A polyether imide sheet is quenched while atmospheric pressure is being lowered after the same has been maintained under pressurized atmosphere of gas under a state wherein the polyether imide sheet is heated at the temperature of more than 130 deg.C and less than the glass temperature. As the gas, a thing which neither dissolves PEI nor generates a craze and is abundant in an adsorption quantity to the PEI is favorable. Although flon gas, carbon dioxide, nitrogen gas, helium gas, argon gas and propane gas are usable definitely, the flon gas whose boiling point is 40--40 deg.C is especially favorable. Pressurization is favorably carried out at pressure falling within a scope of 30-100kg/cm<2>. As for a period of time keeping the sheet within gaseous atmosphere, though it may be desirable that the higher the temperature and pressure become the shorter the period of time becomes, it is desirable to keep the same for more than three hours at least, which is desirably good to keep for more tan 200hr. Then the sheet is quenched. As a refrigeration medium for quenching, water cooled by a chiller, methanol/dry ice and liquid nitrogen are available.

Filed: 1981-11-10
Abstract: PURPOSE:To apply sound welding despite the presance of minor gaps in the  fayed surfaces of the work by oscillating a member provided over the optical  path for laser light thereby moving the irradiating end of the laser light zigzag. CONSTITUTION:An electromagnet 18 is excited with an exciting coil 18a to generate magnetic lines phi of force indicated by broken lines between electrodes. When electric current I is conducted in an arrow direction to conductive springs 16a, 16b installed so as to cross the magnetic lines phi of force, the couple P acts upon the springs 16a, 16b respectively in the arrow direction. The couple is proportional to the current I and the angels phi of displacements of the springs 16a, 16b by the couple P are proportional to the couple P. Therefore the reflected light 2a of laser light 2 displaces accurately to the reflected light 2a shown by the broken lines in proportion to the current I. Thereupon, when the current I is changed periodically with an oscillator 20, the laser light 2 can be oscillated in follow up to said change.

Title: Shaving and polishing apparatus for continuously correcting outer shape of railroad track
Inventor: ROMORO PANETSUTEI
IPC: E01B31/17
Filed: 1980-12-19
Abstract: Device intended to be displaced along track rails and comprising a frame (2) guided by the rail (1) provided with a grinding wheel (6) which grinds through its periphery. To uniformly distribute the wear resulting from contact with the rail on all its active surface, the grinding wheel (6) is driven, in addition to the continuous rotation supplied by a driving motor (7), in an alternating motion transverse to the track by means of an actuating mechanism. This actuating mechanism comprises a motor-gear assembly (13) driving an eccentric shaft (9) on the eccentric of which the movable support (8) is hinged. To avoid the formation of sinusoidal traces due to the grinding, the amplitude a of the reciprocal movement is related by the equation a SIMILAR l-f to the width l of the active surface of the grinding wheel and to the width f of the portion of the profile of the rail which is ground.
