Title: Manufacture of polishing tape
Inventor: SUZUURA YASUKI
IPC: B24D11/00
Filed: 1987-03-17
Abstract: PURPOSE:To enable the precision finishing of a polished surface by forming a hard coat layer in one or more kinds of resins of melamine, polyurethane, silicone, fluorine or acrylic resin or the like and forming on the other surface a polishing layer. CONSTITUTION:On one surface of a polishing tape consisting of polyethylene terephthalic film and the like, a hard coat layer is formed directly or through an undercoat layer to give adhesion in a single resin or mixed resins selected from resins of melamine, polyurethane, silicone, fluorine or acrylic resin by means by a dry heat effect, EB or UV irradiation hardening or the like.

C, N and C+N are restricted from the viewpoint of deterioration in the weldability and formability, Si in the formability, Mn in the formability and weather resistance, and S in the weather resistance. The upper limit of Cr is decided not to deteriorate the formability. Al is restricted since it deteriorates the weather resistance and hot workability. The upper limit of Mo is decided not to deteriorate the formability and weldability. Excess Ni and Cu deteriorate the formability, and the corrosion resistance is also deteriorated by excess Cu. Excess Ti and Nb deteriorate the toughness, and the ratio  between Ti+Nb and C+N is restricted to prevent the intergranular corrosion.

Abstract: PURPOSE:To easily dry and polish tableware, etc., in a short time by containing an elastic body or a granular body consisting of a soft synthetic resin in a vessel, forming a fluidized bed by blowing up air from the lower part, and arranging tableware, etc., in the fluidized bed. CONSTITUTION:When air is subjected to compressive feed to an air distributing chamber 5 from a multistage blower 7 in a state that a granular body 4 is contained in a vessel 1, air is blown up equally from the bottom face of the vessel 1 through a straightening vane 3, and a fluidized bed of the granular body 4 is formed in the vessel 1. In such a state, when a holding basket 11 for holding tableware 20 washed in water is suspended and supported in the vessel 1, waterdrops adhering to the surface of the tableware 20 are eliminated by the granular body which diffuses and flows and dispersed to many granular bodies 4, and also, air flows by coming into contact with the granular body 4 and the whole surface of the tableware 20. Also, the granular body 4 comes into collision frequently and uniformly with the surface of the tableware 20 and comes into frictional contact therewith. In such a way, the tableware can be dried and polished beautifully simply and in a short time.

Abstract: PURPOSE:To obtain a high power fluorescent lamp having high efficiency by installing a separation wall formed with an ultraviolet ray transmitting material almost in the center within a tube over from the vicinity of one electrode to the vicinity of another electrode. CONSTITUTION:A separation wall 7 formed with a material such as quartz glass which transmits efficiently 254nm ultraviolet rays is installed almost in the center within a tube over from the vicinity of one electrode 4 from the vicinity of another electrode 4 in a fluoresceny lamp 1 to form two discharge paths 6a, 6b in a tube length direction. The discharge between the electrodes 4 is conducted only in the path which has lower discharge impedance in two discharge paths 6a, 6b, and ultraviolet rays generated by the discharge are transmitted through the separation wall 7 and irradiated to another discharge path to unify emission to the outside. Therefore, in order that the cross section of the discharge path becomes semicircular, recombination of electrons and ions is acclerated and the saturation level of light output is increased to improve the efficiency.

Title: Interruption processing system
Inventor: FURUYA TSUKASA
IPC: G06F13/24
Filed: 1987-03-17
Abstract: PURPOSE:To prevent a system from generating overrun of bus transfer capacity or performance down by restricting an interruption request only to the one having an interruption level higher than that of processing being executed by a CPU to remove an excessive interruption request. CONSTITUTION:Even if an interruption request is generated from one of peripheral control devices 4-1-4-N, the CPU suspends the request during the executing of processing higher than the interruption level. At the time of transferring to new processing having different interruption level, the CPU sends interruption permitting information including the interruption level of the new processing in executing to respective peripheral control devices to generate an interruption again. When the interruption having interruption level higher than that of the interruption permitting information is suspended, the peripheral control device out of the ones 4-1-4-N resends the interruption request to the CPU 2. Consequently, data can be prevented from being lost due to the overrun of bus transfer capacity or the system can be prevented from generating performance down.
