Filed: 1991-09-03
Abstract: PURPOSE:To prevent the dew condensation on a valve part exposed to the atmosphere by connecting the synthetic resin leg cylinder of an operation device to a valve shaft cylinder slightly protruded from a valve body. CONSTITUTION:In a dew condensation preventing valve 1, as a valve shaft cylinder 2a is only slightly protruded form a valve body 2, the connecting part between the valve shaft cylinder 2a and the leg cylinder 3a of an operation device 3 is covered with a heat insulating material 11 covering the valve body 2.

Abstract: PURPOSE:To execute data transfer at a high speed by constituting the titled system so that data transfer between different memory blocks can be executed in one cycle. CONSTITUTION:When executing data transfer, in case when its transfer origin and transfer destination exist in different memory blocks, a '0' signal is applied to an adder/subtracter 61 by outputting an address command 1 from a CPU, and an even address for a memory block 11 of the transfer destination is set to an offset '0'. On the other hand, a difference in addresses between the transfer origin and the transfer destination of data is set in advance to an offset register 5. As a result, prescribed even address and odd address are given to the memory blocks 11, 12, respectively, from each adder/subtracter 61, 62. In this state, when the CPU reads out data from the transfer origin memory block 11, and the data is loaded on a bus 2 so as to be written on the transfer destination memory block 12, the data transfer between both the memory blocks 11, 12 can be ended in one cycle.

Title: Corrugate synthetic resin film or sheet with air permeable hole and manufacture thereof
Inventor: JINNO KATSUSHI
IPC: B29C53/26
Filed: 1988-10-03
Abstract: PURPOSE:To obtain a corrugated sheet material, which is fully flexible in the repeating direction of corrugations and favorably air-permeable, by a structure wherein each corrugation is cut in pieces by channels, which run normal to the corrugation, and an opening is provided at the side face of the cut corrugation. CONSTITUTION:The corrugated plastic film or sheet concerned is substantially made in the form of a corrugated sheet or film having the thickness of from several millimeters to several ten micromillimeters out of all the film-making thermoplastic resin such as polyethylene, polypropylene or the like by injection molding or other means. Stock resin may well contain additives such as plasticizer and the like, when necessary. As essential constitution, channels, which run so as to meet corrugations, are equipped. The channels run as a rule from the end of the sheet to the end so as to pass through the sheet. However, as the case may be, the channels can arbitrary be cut halfway. In the extreme case, the corrugations and the channels are cut each other by the half pitch of the corrugations, resulting in showing the rhombiform external appearance. A through hole is formed at the edge face of each corrugation cut by each channel or at one side face or both side faces, which are parallel to the channel, of the corrugation. The corrugations 2, 2... constituting a thermoplastic sheet 1A produce a large number of independent roof-like parts 2a, 2a..., each of which is cut in a piece by the channels 3, 3... traversing perpendicular to the corrugation. At the same time, through holes 4, 4... are bored at the edge face on this side of the figure of the respective independent roof-like parts. In this case, the depth of the bottom part (the through part) 2b of the corrugation (the distance from the crest of the wave to the bottom of the wave) is equal to the depth of the channel 3.

Abstract: PURPOSE:To form a thin film of a metal, etc., by cracking, etc., of a reaction gas to a specific part by a thermo-CVD method, by forming a preliminary film having a specific spectral absorption characteristic to the desired part of the surface of a substrate consisting of a semiconductor, etc., then projecting heat rays on the film under the supply of the reaction gas. CONSTITUTION:An SiO2 film is formed by thermal oxidation on a semiconductor wafer consisting of Si, etc., and an aperture is provided by processing such as etching to this film to expose the Si. This Si wafer 2 is put into a quartz reaction tube 1 and the inside of the tube is evacuated to a vacuum from a discharge port 5. The reaction gas is then supplied thereto from a gas supplying port 4 to form the thin film consisting of W, Mo, etc., in the aperture where the Si is exposed. WF6 and Ar are supplied to the tube from the gas supplying port 4 and light of a specific wavelength is projected from a lamp 3 for heating to heat up the thin film formed part mentioned above up to the cracking reaction temp. of the WF6 so that the W is reduced and deposited on the thin film. Since the thin film does not exist in the SiO2 part, the temp. does not rise up to the cracking temp. of the WF6 and the W does not exist; therefore, the film consisting of the W is formed only in the thin film formed part by the thermo-CVD method.
