Title: Device for refrigerating cycle
Inventor: ITAMI TSUGIO
IPC: F25B5/02
Filed: 1988-06-29
Abstract: PURPOSE:To make it possible to operate a refrigerating cycle which has a plurality of evaporation temperatures with a high energy consumption efficiency by controlling the coolant flowing in a flow channel switching channel and providing a flow channel switch device which switches flow channel to the direction in which either one of a second evaporator or evaporator in refrigerating cycle and the suction side of a compressor on a low stage side are in communication. CONSTITUTION:When a refrigerating chamber and cold storage chamber are both cooled, two-way solenoid valves 13 and 5 are changed over to opening and an one-way solenoid valve 14 to closing by the instruction of a control section 16. Liquid coolant of low pressure which is reduced in its pressure by a pressure reducing device 7 for refrigeration is supplied to an evaporator 8 for refrigeration, and liquid coolant of intermediate pressure which is reduced in its pressure by a pressure reducing device 11 for cold storage is supplied to an evaporator 10. With this arrangement the evaporator 8 for refrigeration evaporates at evaporation temperature which responds to the low pressure coolant and the evaporator 10 for cold storage evaporates at evaporation temperature which responds to the intermediate pressure. By the way the coolant of intermediate pressure that evaporates in the evaporator 10 for cold storage is sucked into a second compressor section 4 and the coolant of low pressure that evaporates in the evaporator 8 for refrigeration is sucked into a first compressor section 3. Consequently an efficient operation is achieved because evaporation is made at most suitable temperature for refrigeration and cold storage.

Abstract: PURPOSE:To increase the joint cross-sectional area of molten resin and consequently improve the weld strength of welded resin items by a method wherein an empty space is provided at the joint area of the resin items, both of which are made of the same kind of material, and the portion, in which said empty space is provided, is spot-welded with an ultrasonic horn. CONSTITUTION:An empty space is formed at the joint area of resin items 3 and 4 by providing a recess on the resin item 3. The welding of the resin item 3 to the resin item 4 is done by piercing resin material and at the same time by melting resin with the convex part 2 at the tip of an ultrasonic horn 1 by applying pressure to the horn 1. The molten resin flows in the empty space 5 at the joint area so as to fill said space. The volume of the empty space 5 is set by judging from the anticipated amount of molten resin. The section of the joint area after welding is shown in the figures (b) or in the state that molten resin 6 is sandwiched between the resin items 3 and 4. In addition to the above-mentioned method, another method to form the empty space 5 at the joint area is to provide a loop-like convexity 7, which forms a dam, onto one of the joint area of the resin items 3 and 4.

Abstract: PROBLEM TO BE SOLVED: To lower the dynamic friction coefft. with a tape and to improve the tape traveling property by allowing skin layer parts and the exposed part of filling parts to coexist on the outer peripheral surface of a stationary and/or rotary drum for sliding with the magnetic tape. SOLUTION: The stationary drum 1 is formed by filling fibrous fillers 6, spherical fillers 7 for imparting a sliding characteristic and electrical conductivity to a polymer compd. and microfillers 8 formed by pulverizing these fillers into this compd. and injection molding such compd. Projecting and recessed parts 3, 4 are formed on the surface of the drum 1 and the surface is covered with the skin layer 9. The layer 9 is filled with the fillers in the smaller amt. and is mostly the polymer compd. When the magnetic tape is slid with such drum 1, the projecting parts 3 are worn by the pressure at the time of sliding and turn to the projecting parts 3' and the fillers 6, 7, 8 are exposed on the drum 1 surface. The dynamic friction coefft. with the tape 2 is, therefore, made small after the wear and the good traveling of the tape is assured.  In addition, the electrical conductivity is imparted to the outer peripheral surface of the drum 1.

Abstract: PURPOSE:To enhance the measuring accuracy of a thermometer by perfectly eliminating a mechanical operation part, by blocking infrared rays allowed to irradiate a pyroelectric element from an object to be measured by a liquid crystal plate in a time sharing manner. CONSTITUTION:Because a liquid crystal plate 1 repeats a transparent state and an opaque state at several cycles per a sec by the control signal from a liquid crystal plate control part 3, a pyroelectric element 2 is irradiated with infrared rays at every constant cycle. Therefore, a signal corresponding to the change component in the irradiation quantity of infrared rays is outputted from the pyroelectric element and receives full-wave rectification and smoothing in a temp. detection part 4 while the smoothed signal is outputted as a temp. display signal. Thus constituted infrared temp. sensor has no mechanical operation parts at all and the possibility of the lowering in the measuring accuracy of a thermometer caused by friction or strain is eliminated.
