Title: Positive displacement fluid machinery
Inventor: MITSUYA SHIYUNICHI
IPC: F04C18/04
Filed: 1997-03-19
Abstract: PROBLEM TO BE SOLVED: To secure the stable behavior of a rotary piston so as to improve its performance and reliability, by arranging holes in positions especially opposed to a intake port and an exhausting port, as means by which the rotary piston is slewed between end plates through lubricating oil. SOLUTION: Oil supply means is arranged on a surface opposed to the end plate of a displacer (rotary piston) 3 by which operational fluid is moved. Namely, an oil groove is arranged, by which lubricating oil supplied from a shaft is supplied to both end surfaces of the rotary piston 3. An equal pressure hole 4d which has approximately the same diameter as an exhausting port 5a and is formed into a sunk hole shape, is arranged in a position especially opposed to the exhausting port 5a formed in the auxiliary bearing 5 of a main bearing 4. Hereby, force which intends to push the rotary piston 3 through the exhausting port 5a, is entered into the equal pressure hole 4d by making the operational fluid as a medium, and functions as force that pushes the rotary piston 3 also from the equal pressure hole 4d. Further, force functions in the same manner when an equal pressure hole 5d is formed in a position opposed to an intake port 4a.

Title: Device for taking measure against power unbalance
Inventor: YOSHIDA TOSHIO
IPC: H02J3/26
Filed: 1991-03-29
Abstract: PURPOSE:To maintain a current balanced state on a commercial power supply side even when the power supply line is switched from the commercial power supply side to a by-pass power supply path side due to the fault of an uninterruptible power supply(UPS) while the power supply is made from the UPS to a load. CONSTITUTION:When electric power is supplied to a single-phase load AC through a UPS connected to commercial power supply AC and by-pass power supply path BPS connected in parallel with the UPS, the electric power is usually supplied to the single-phase load from the UPS. However, when the UPS becomes defective, a semiconductor switch THSW operates and the single- phase load is fed with electric power through the by-pass power supply path BPS. Thereafter, a change-over switch SW is switched and the electric power from the path BPS is supplied to the load through the switch SW. While an unbalanced current flows to the power supply side when the power supply is made through the path BPS, the unbalanced current is dissolved by means of an active filter AF provided on the power supply side.

Title: Light quantity adjusting device
Inventor: KAI FUTOSHI
IPC: G03B9/02
Filed: 1994-04-04
Abstract: PURPOSE:To prevent the faulty attaching position of an optical filter to a movable light shielding member by providing the light shielding member with an optical filter part constituted by integrally molding with the member. CONSTITUTION:A diaphragm blade 10 is obtained by integrally molding a diaphragm blade main body part 10 and the optical filter part 10b by press molding using acrylic resin as the material. After molding, light shielding painting is executed to the surface of the main body part 10. The filter part 10b is formed so that its thickness may be gradually decreased as it is separated from the aperture edge of the diaphragm blade. Namely, the thickness of the filter part 10b is increased on a side where the diaphragm becomes a small aperture, so that light transmissivity is lowered. Paint adhesion preventing coating is performed to the surface of the filter part 10b so that light shielding paint does not adhere thereto. Since the diaphragm blade, that is, the movable light shielding member 10 is constituted so that the filter part 10b and a light shielding member main body are integrally molded, various effects such as the reduction of producing man-hour and the improvement of quality and yield are obtained.

Title: Dicyclopentadiene derivative containing fluorine and its production
Inventor: YOSHIMURA HIKOJI
IPC: C07B61/00
Filed: 1994-02-28
Abstract: PURPOSE:To obtain a new compound, reactive with an organic polymer and useful as a modifier capable of imparting water and oil repellencies, antifouling properties, weather resistance and durability to the polymer. CONSTITUTION:This compound is expressed by the formula (Rf is a 4-16C perfluoroalkyl). Furthermore, this method for producing the compound is to carry out the addition reaction of a 2-(perfluoroalkyl)ethanol expressed by the formula Rf(CH2)2OH with dicyclopentadiene in the presence of an acidic catalyst (e.g. BF3.Et2O) in an atmosphere of an inert gas (e.g. nitrogen gas) by heating. The compound expressed by the formula is useful as a new modifier capable of smoothly and effectively introducing fluorine into an organic polymer by the polymeric reaction through a functional group obtained by reacting a double bond in the molecule with other compounds or copolymerization of the double bond with other monomers. Since the compound having a larger number of carbon atoms of Rf has great characteristic effects of the contained fluorine and the solubility and compatibility with the compound to be an object for modification are deteriorated, a 4-16C compound is preferred.

Abstract: PURPOSE: To plan to save man-hour by forming a hull with ribs integrally.  
     CONSTITUTION: A sheet 3 constructed to have three layers of plastic plates, surface layers 2, 2' of which are of flat plates and an intermediate layer 1 of which is of foaming plastic, is pinched by vacuum forming metalic molds 6, 7 after heated and softened, and spaces 8, 9 provided in the molds are sucked by vacuum, and thereby, the intermediate layer 1 is separated due to low strength of the foaming plastic while the surface layer 2, 2' are contacted with the metalic molds 6, 7 closely, and thus, a hull 5 together with predetermined protuberances 4 are formed by vacuum. By this method, protuberances 4 formed with the hull 5 integrally reinforce a boat by serving as ribs and man-hours for fixing the ribs to the hull 5 may be saved. Further, spaces in the protuberances 4 serve as bouyant chambers of the boat and the safety thereof may be improved by preventing sinking upon being immersed by water.

Abstract: PROBLEM TO BE SOLVED: To prevent the increase in a dissolved oxygen concentration in ultrapure water by a method in which raw water is irradiated with ultraviolet rays, free radicals in the raw water are adsorbed, and ionic components are removed from the raw water in which free radicals are adsorbed. SOLUTION: Primary pure water produced by a primary system is supplied to an ultraviolet lamp oxidation device 9 and irradiated with ultraviolet rays of 180-190 nm. Next, the water is sent to a free radical adsorption device 10 to adsorb contained free radicals. The device 10 is filled with a free radical adsorbent having the crosslinked structure of a phenol-formalin based condensate. The raw water with free radicals adsorbed is sent to a mixed bed type ion exchange apparatus 11 filled with a strongly basic anion exchange resin, and ionic components are removed. In this way, the dissolved oxygen concentration of the treated water can be reduced as compared with that of water passed through a by-path line 12 without passing through the free radical adsorption device 10.
