Patent JP-H01230964-A (JP)
Title: Absorption refrigerating machine
Inventor: TANAKA TAKAO
IPC: F25B15/00
Filed: 1988-03-08
Abstract: PURPOSE:To make it possible to melt the crystals from an absorption solution at a solution heat exchanger and near the outlet of high concentration liquid by providing a mechanism which controls a cooling fan so as to reduce its rotational speed when a temperature sensor installed on an overflow pipe detects a temperature which is over a specified temperature. CONSTITUTION:When an absorbing solution is crystallizing in a heat exchanger 14 or near its high concentration solution outlet or the absorbing solution has crystallized, the liquid face of the absorbing solution in a generator 1 rises, and when the liquid surface rises above the connection position of the generator 1 and overflow pipe 19, the absorbing solution flows into an absorbing solution reservoir 8 through the overflow pipe. This absorbing solution flowing into the reservoir 8 has a temperature higher than that of the absorbing solution which was cooled in an absorber 7 and flew into the absorbing solution reservoir. When the temperature sensor 36 detects the temperature of the high temperature absorbing solution which passes through the overflow pipe, a mechanism 37 which controls the rotation of a cooling fan 34 reduces the rotational speed of the cooling fan. As a result, the heat radiation from an absorber 7 is reduced and the temperature of an absorption refrigerator as well as the pressure in the generator 1 rises.

Title: Magnetic head
Inventor: IWASAKI MASAHIRO
IPC: G11B17/32
Filed: 1987-03-11
Abstract: PURPOSE:To reduce the damage of a rotating magnetic sheet due to ridge line parts to considerably extend the life of the sheet by forming ridge line parts of a head, which are orthogonal to the radial direction of the sheet, into curved surfaces of a part of a cylinder surface. CONSTITUTION:The ridge line part formed between a slide face 11a of a magnetic head and a side slope 11b on the inner peripheral side in the radial direction of the magnetic sheet and that formed between the slide face 11a and a side slope 11c on the outer peripheral side in the radial direction, namely, ridge line parts orthogonal to the radial direction of the magnetic sheet are formed into curved surfaces of a part of a cylinder surface. Since ridge line parts are formed into curved surfaces, stress is not concentrated to the sheet even if the magnetic head is set to a height higher than a prescribed value or ridge line parts are strongly brought into contact with the sheet in the circumstance where the sheet rigidity is increased because of a low temperature or the like, and the damage is reduced to considerably extend the life of the sheet.

Filed: 1998-03-06
Abstract: PROBLEM TO BE SOLVED: To prevent the clogging of a solid material passed through a suction opening between an impeller and a pump casing, by inclining at a down slope from a peripheral side toward the suction port, the bottom surface of a spiral chamber in which a part of the lower end side of the impeller is placed so that the passing particle diameter of the spiral chamber can be enlarged. SOLUTION: The bottom surface of a spiral chamber 9 in which a part of the lower end side of an impeller 3 is placed is formed by a slant surface 9A inclined at a down slope from a peripheral side toward the upper end of a suction port 6. Thusly, the bottom surface of the spiral chamber 9 is formed by the slant surface 9A inclined at the down slope from the peripheral side toward the upper end of the suction opening 6, thereby the passing particle diameter D1 of the spiral chamber 9 can be enlarged up to the aperture D of the suction port 6 and a discharging passage 10. Therefore, a solid material passed through the suction port 6 can be passed through the discharging port 10.

Title: Refrigerator
Inventor: MOCHIZUKI OSAMU
IPC: B29C39/24
Filed: 1994-02-28
Abstract: PURPOSE:To ensure that no leakage occurs even when a foamed heat insulating material whose start of foaming is quicker than a conventional are is used by providing an injection aperture seal so that the foam heat insulating material does not leak from the injection aperture through which the heat insulating material is injected into a refrigerator at the time of injection. CONSTITUTION:An injection aperture seal 13 is bonded around all the entire periphery of an injection aperture 9. In addition, a cross slit 15 is formed in the center of the injection aperture. A contact area with an injection head 11 is larger than that with a tongue-shaped injection aperture seal which is used conventionally and installed in a cantilever state. Consequently, a clearance around the injection head 11 is small. Further, a layer of a material with a low modulus of elasticity is provided on the rear of the injection aperture seal 13 and therefore, the contact area can be made larger. In addition, the injection aperture seal 13 is prevented from becoming swollen due to the pressure of the foamed heat insulating material, so that a plate material with a high modulus of elasticity is provided on the rear of the injection aperture seal 13 in a cantilever state to reinforce the injection aperture 9.

Abstract: PURPOSE:To achieve lift-off easily and avoid creation of a recess in a GaAs substrate even after a heat treatment process by a method wherein a novolak system photoresist film is formed on an organic silane film formed on the GaAs substrate and, after patterning, metal is deposited on the exposed GaAs substrate and the novolak photoresist film left after patterning and the organic silane film is removed. CONSTITUTION:A GaAs substrate 1 is coated with an organic silane film 2 with a thickness of 100-500 Angstrom  applied by a spinner method and a novolak photoresist film 3 with a thickness of about 8000 Angstrom  is formed on the organic silane film 2 by coating. After the organic silane film 2 and the novolak photoresist film 3 are baked and a required pattern is formed, the exposed surface of the GaAs substrate 1 is cleaned by an O2 plasma. Then metal 4 composed of Au/Ni/Au-Ge is deposited over the whole surface. Then the metal 4 on the novolak photoresist film 3 is removed. After organic washing and so forth, the metal is alloyed. The organic silane film 4 which is dissolved and decomposed by solvent easily is provided between the GaAs substrate 1 and the novolak photoresist film 3. Therefore, the organic silane film 4 relieves the adhesiveness between the GaAs substrate 1 and the novolak photoresist film 3 so that easy lift-off can be provided. Even after alloying, creation of a recess near the end of the metal on the GaAs substrate can be avoided.
