Filed: 1996-10-15
Abstract: PROBLEM TO BE SOLVED: To provide a method capable of manufacturing fiber reinforced thermoplastic resin foams under ready and high productive conditions even in situations where the cross-section is complicate and foaming magnification is high. SOLUTION: One or a plurality of fiber reinforced thermoplastic resin sheets 110a, 110b are formed into hollow bodies T continuously, and a foamable thermoplastic resin sheet 111 is supplied therein in which foamable thermoplastic resin particles 111a are integrated in a state being dispersed uniformly by a foamable resin thermoplastic resin film body 111b, followed by filling foam resin in the plasticized hollow body T through heating so as to form the hollow body T in a desired cross-sectional shape along a regulation material 48 by the foam pressure.

Filed: 1994-11-07
Abstract: PURPOSE: To provide a marking band capable of attaching member marking by a single operation, without special technical training for a plumber and intending to prevent a marking mistake and to improve making identification. CONSTITUTION: This marking band 10 has a reversion shape in a condition where force is not applied (B), but has a platelike shape (shape memory condition) having a cross section shape (A) by applying force by the following principle when the marking band 10 is extended. The principle of shape memory can be expressed as M>=aX-(b+p)Y (M: memory maintenance, X: memory maintenance shape, a: memory maintenance resiliency, Y: reversion resiliency, p: external force). When the marking band 10 has a shape memory condition, force (negative external force), inverse to force at the time of the extension of the marking band 10, is acted not to satisfy the relation in the above principle, thereby returning the band 10 into a reversion condition.

Filed: 1995-10-20
Abstract: PROBLEM TO BE SOLVED: To enable oil to be easily returned back to a compressor by a method wherein an evaporator and a header are heated, a temperature of the evaporator is detected, and an oil returning is carried out for controlling a low temperature part-heating means and a compressor by applying a sensing output of an evaporator temperature heating means. SOLUTION: During operation of a compressor 1, a temperature of an evaporator 4 or a header 5 is decreased, and reaches a predetermined temeprature. Then, an evaporator temperature sensing means 10 detects that the temperature is less than a predetermined temperature and outputs it to an oil returning control means 11. The oil returning control means 11 outputs a signal to the low temperature part heating means 9 under a state in which the compressor 1 is being operated. The low temperature part heating means 9 starts to heat the evaporator 4 and the header 5 and further starts an oil returning operation. Temperatures of the evaporator 4 and the header 5 are started to increase and reach a predetermined second temperature. Freezer oil 7 stagnating at the low temperature part is improved in its flowability due to a reduction in viscosity as its temperature is increased and it is returned back to the compressor 1.

Inventor: NAKAMURA SHINICHI
IPC: G01D5/02
Filed: 1985-12-04
Abstract: PURPOSE:To enable freely shakable support without generating the shift of a fulcrum position, by fixing a plurality of leaf springs, which are alternately arranged so as to cross the position of the fulcrum line due to the abuttment of the corner edges of a pair of block materials at a right angle, to block surfaces opposed to each other. CONSTITUTION:Three leaf springs 5a-5c are alternately arranged along a fulcrum line P-P, which is determined by the abuttment of corner edges 1a, 2a coming to the orthogonal positions of block materials 1, 2, so as to be crossed at right angles and fixed to the mount holes 6 provided to the mutually opposed block surfaces with rivets. By this fulcrum structure, for example, when the side of the block material 1 is fixed, the block material 2 supported through three leaf springs 5a-5c arranged so as to be crossed at right angles can shake around the fulcrum line P-P being the center of rotation in a range determined by the elastic deformation of the leaf springs 5a-5c. By this method, a simple fulcrum support structure applying highly accurate shaking revolution without generating backlash can be obtained.

Abstract: PURPOSE:To efficiently and safely recover oil by providing a piston ring to be pushed down by the pressure of replacing water from its supply port in oil recovery and utilizing the pressure balance between oil and water in a rotor. CONSTITUTION:Replacing water is supplied from its supply port 14 and accumulated in a chamber 15, hence the piston ring 8 is pushed down by the water pressure, and a passage 16 is closed.
