Title: Terminal washing tank elevating device
Inventor: NOTOMI RYOSUKE
IPC: G21C19/37
Filed: 1993-11-16
Abstract: PURPOSE:To prevent the radioactive contamination of operating water, the mass generation of radioactive waste and water leak from the lower part of a cylinder. CONSTITUTION:The upper part of a piston rod 6 piercing the upper part of a cylinder 7 is fixed, and the cylinder 7 is supported elevatingly by a piston 12 and the piston rod 6 so as to make the cylinder 7 movable. A basket 3 for storing the end of spent fuel is fitted to the lower part of the movable cylinder 7 through a rod 11. The carry-in of radioactive material to the cylinder 7 from a washing tank is thereby eliminated completely so as to prevent the radioactive contamination of operating water. The complete elimination of carry-in of radioactive material to the cylinder 7 from the washing tank reduces the possibility of radioactive contamination of operating oil of a hydraulic press by a large margin. The operating water can be thereby reused, and the generated quantity of radioactive waste is reduced. Since the piston rod 6 pierces the upper part of the cylinder 7 and the lower part of the cylinder 7 is closed, water leak from the lower part of the cylinder 7 is prevented.

CONSTITUTION:A chip 5 is bonded by conductive epoxy resin to a die pad 6, and the chip 5 and leads 8 are wired by bonding wirings 7. Then, glass 2 is disposed inside the right and left bonding wirings 7 wired to the chip 5 to be located directly above a picture element portion. Here, aluminum wirings are formed on the surface of the chip 5 so that the surface becomes irregular. Thus, when the glass 2 is placed directly on the chip 5, wirings 3 projected mostly highly contact the glass 2, and a space 4 is formed in the height of the wirings 3 on the picture element portion lower than the wirings 3. The entirety is disposed in a mold in this state, a polymer material 1 is fed by pouring type or transfer molding method from its outer periphery and cured. At this time, the glass 2 is bonded fixedly to the material 1. When the material 1 is cured, the mold is opened, and the molded product is removed from the mold. Thus, the sealed product can be sharply reduced in thickness to decrease its size.

Abstract: PURPOSE: To prevent the formation of a water-way along the outsides of pipe bodies and to make it possible to reduce the following and conveying space to variations in the ground by providing an impervious wall formed of a rubber plate capable of elasticity and deformation to a gutter pipe buried in the ground. CONSTITUTION: An impervious wall 8 formed in the shape of a front viewed square of an elastic rubber plate capable of elasticity and deformation is inserted in the circumference of a specific pipe body 5 of a gutter pipe 1 formed by connecting a large number of pipe bodies 5 and is mounted, and the circumferential edge of an opening section is held with a mounting ring 7 and a holding ring and is fixed. A space between the internal circumference of the mounting ring 7 and the circumference of the pipe body 5 is sealed with a rubber ring.  The gutter pipe 1 formed by such a method is buried in a levee 3, and when high waters in a river 2 are discharged to another place, the flow of water along the gutter pipe 1 is prevented by the impervious wall 8 to prevent the formation of a water-way 17 or to prevent water from passing through from a space between the mounting ring 7 and pipe body 5. Since the gutter pipe 1 is formed of the rubber plate capable of elasticity and deformation, the damage in the previous wall 8, mounting ring 7 and pipe body 5 is prevented by following variations in the ground.

IPC: H01J29/04
Filed: 1995-11-06
Abstract: PROBLEM TO BE SOLVED: To provide a necessary vacuum degree to drive an electron source substrate by suppressing gas evolution emitted from a circuit which composes the electron source substrate. SOLUTION: A coating liquid 22 is compressed by a compressor 23, finely granulated in a finely granulating apparatus 24, and conveyed to a spraying nozzle 20. Then, the resultant fine particles of the coating liquid 22 are made to bear electric charge and sprayed through a nozzle. The fine particles come flying to a substrate 26 due to the potential gradation between the spraying nozzle 20 and a conductive stage 27. The electric charge due to the fine particles which come flying to a conductive layer 28 is removed through an earth by earthing the conductive layer 28 and on the other hand, the electric charge due to the fine particles which come flying to other non-conductive parts is accumulated. The coating liquid is thus selectively applied to the conductive layer 28.  As an electron source substrate produced in this method, 10, 11 in the figure stand for element electrodes, 12 for an insulating layer to separate a first wiring layer and a second wiring layer, and 15 for a thin film for electron emitting part formation.

Title: Engine cooling device
Inventor: SUGIMOTO TATSUO
IPC: F01P7/16
Filed: 1992-10-26
Abstract: PURPOSE:To control engine cooling water temperature adapting to operating condition of air condenser. CONSTITUTION:A high temperature setting thermostat 23 and a low temperature setting thermostat 24 are provided in parallel in an engine cooling circulating circuit 12, and a solenoid valve 25 is provided in series to the low temperature setting thermostat 24. When the operation rate of a compressor 13 is a set value or more, the solenoid valve 25 is opened so as to make engine cooling water flow toward the low temperature setting thermostat 24 side. It is thus possible to control the engine cooling water temperature rather at a lower level, and also suppress the temperature rise caused by a radiator 21 to a low level so as to suppress the temperature rise in an engine room. When the operation rate of the compressor 13 is lower than the set value, the solenoid valve 25 is closed so as to make engine cooling water flow toward the high temperature setting thermostat 23 side. It is thus possible to control the engine cooling water temperature rather at a higher level so as to improve engine efficiency, and improve room heating performance.

Title: Continuous production process of trichloropentafluoropropane
Inventor: KAWASAKI TORU
IPC: B01J27/125
Filed: 1990-10-26
Abstract: PURPOSE:To produce the title high-purity substance in high yield by subjecting tetrafluoroethylene and trichlorofluoromethane to addition reaction in the presence of a catalyst of a Lewis acid such as AlCl3 in a specific molar ratio. CONSTITUTION:In producing the title substance by adding trichlorofluoromethane (R11) to tetrafluoroethylene (4F), the existing molecular ratio of 4F and R11 is made 1<=4F/R11 (preferably 1.01<=4F/R11<=10) and the reaction is carried out in the presence of a catalyst of a Lewis acid. Since concentration of R11 in a reactor is minimized, R11, 4F and the catalyst are continuously fed to the reactor and the reaction mixture is successively taken out so that concentration of each component can be maintained constant and if 4F is used in excess, the concentration of R11 can be suppressed to the minimum. In the reaction condition, in the case of continuous operation at -20 to 100 deg.C under 0-10kg/cm<2>, retention time of the reaction solution is preferably 1 minute to 10 hours.

SOLUTION: Empty bobbins 17 are inserted from a bobbin inserting port 38 into a bobbin housing box 3 and when the amount empty bobbin 17 housed in the housing box 3 exceeds a specified amount, a bottom plate 32 is rocked downward against a tensile spring 36 following an increase in bobbin weight and, in the end, an attaching part 35 is brought into contact with the lower end of an oblong hole 33. Thus, the bobbin housing space of the bobbin housing box 3 is increased. The empty bobbins 17 are supplied to a peg 29 and when the amount of empty bobbins in the housing box 3 declined below the specified amount, the slope of the bottom plate 32 is changed to a lower direction slope by the spring force of the tensile spring 36 and a pressing force by the bobbin weight is applied in the direction of a lattice conveyor 10.  However, since the amount of empty bobbins is small, the pressing force is prevented from being excessive and the lattice conveyor 10 is smoothly operated.
