Title: Sealant composition and its production
Inventor: SAKASHITA KEIICHI
IPC: C04B16/02
Filed: 1991-03-22
Abstract: PURPOSE:To readily produce a sealant composition excellent in strength, compression recovery and thermal resistance and free from asbestos pollution by simultaneously beating a fibrillated aromatic polyamide fiber and organic fiber and subsequently blending an inorganic binder, etc., therewith. CONSTITUTION:An aromatic polyamide fiber and an organic fiber (e.g. cellulose pulp or hemp) are beaten so as to be fibrillated. The resultant fibrillated fibers, together with an inorganic heat-resistant fiber (e.g. glass fiber or rock wool) are opened. Inorganic particles and an organic binder (e.g. a modified acrylic acid ester copolymer) are then admixed therewith in order. An inorganic cationic flocculant and an acrylamide-based polymer flocculant are further added thereto in order and the resultant mixture is then subjected to the wet method paper- making and subsequently to dehydration press. The inorganic heat-resistant fiber is bonded between small massive flocs composed of the fibrillated aromatic polyamide fiber and the organic fiber by using an organic binder so that the inorganic heat-resistant fibers may three-dimensionally exist and that the inorganic particles may be uniformly dispersed.

Title: Method for forming very small lens at end face of optical fiber
Inventor: ISHIZUKA SATOSHI
IPC: G02B6/32
Filed: 1985-04-19
Abstract: PURPOSE:To easily form a very small lens at the end face of an optical fiber and, at the same time, to accurately align the optical fiber, by making it sufficient to prepare two optical fiber of the same kind. CONSTITUTION:A wedge-shaped tapered section 3 is formed at the end section of an optical fiber 1 with an end face 2 perpendicular to its axis and then the end section is heated and melted so that a circular cross section can be formed at the end section. Then a manufactured optical fiber 10 having an elliptical cross section at the end part of its core layer and another optical fiber 11 of the same kind is put between electrodes 6 and 7 for electrospark heating, with the optical fibers 10 and 11 being faced to each other, and electrospark heating 12 is performed. As the discharging current is gradually increased, a projected section 13 of the core having a curved shape is obtained at the end face of each optical fiber 10 and 11. Then the optical fibers 10 and 11 are brought closer to each other so that the projected sections 13 can be contacted with each other on the axis 14 of the electrodes 6 and 7, and the electrospark heating 15 is again performed. While the heating 15 is performed, the optical fibers 10 and 11 are separated from each other and, when the core projected parts 16 have cone-like shapes, the electrosparking heating is stopped. When the electrospark heating 17 is again performed and the cone-shaped core part is melted, a very small lens 18 having an elliptical cross section is formed at the end face of the optical fiber 10 by surface tension.

Title: Heat dissipation of integrated circuit
Inventor: MATSUURA TAKEO
IPC: H01L23/367
Filed: 1982-05-19
Abstract: PURPOSE:To realize small size and light weight of electronic apparatus as a whole by making thick step by step the heat dissipating plates (heat sink) as the plate becomes far from the card frame. CONSTITUTION:A printed wiring board 1 is used as a heat sink and comprises a heat dissipating plates 2 which become thinner step by step as the plate becomes far from the contact part with the card frame 5 mounted. Therefore, the quantity of heat radiating plate 2 when the heat 7 generated from integrated circuit is transferred to the card frame 5 through the heat dissipating plate 2 becomes high as is coming close to the card frame 5. Therefore, the heat dissipating cross section becomes large proportionally, not lowering a heat dissipating efficiency. Moreover, the heat dissipating plate 2 is thinner at the center area and weight is also reduced in proportion to it. Accordingly, weight of an apparatus as a whole can be reduced.

Title: Paint sludge collector and paint mist collecting system for wet coating room
Inventor: MISU KUNIO
IPC: B05B15/04
Filed: 1994-03-30
Abstract: PURPOSE:To improve sludge collection efficiency in a paint sludge collector which is used for a process in which water, which contains paint sludge and is stored in a water tank in a wet coating room, is introduced to the collector and purified by removing the sludge to be returned to the water tank. CONSTITUTION:A paint sludge collector is equipped with an off-timer function. At the end of operations, when an off-timer button 155 is operated and the power source of a wet coating room is turned off, the prevention of sludge membrane formation on the surface of stored water and the dispersion of the sludge are promoted by a return water flow etc., during the time-measuring term of a timer 159. Since showering water or a water membrane does not work on water stored in the water tank when the operation of the coating room is stopped, the agitation in the water tank by the water flow is reduced, allowing the sedimentation of the sludge. Efficient sludge collection can be carried out by sucking the concentrated sludge with a pump 3.
