IPC: F25B1/10
Filed: 1991-02-08
Abstract: PURPOSE:To reduce the amount of refrigerant by condensing gas refrigerant separated by an air/liquid separator with liquid refrigerant and supplying the separated refrigerant to a refrigeration evaporator on one side and supplying the rest of the liquid refrigerant to a cold storage evaporator on the other side. CONSTITUTION:The gas refrigeratnt from a higher stage compressor 1 is condensed by a condenser 2 and then pressure-reduced by an expansion valve 4 and it flows into an air/liquid separator 13 under a two-phase state where the separated liquid refrigerant is partially evaporated in an evaporator 5 housed in a cold storage show case by way of an expansion valve 3. the remaining liquid refrigerant is introduced into an evaporation flow passage 14b of a heat exchanger 14 by way of a solenoid valve 10 and a flow rate control valve 16 where the gas refrigerant separated by the gas/liquid sepaarator 13 is condensed while it is spontaneously evaporated and it is adapted to join the discharge side of a compressor 9 by way of a communication pipe 15. Then, the refrigerant condensed by a heat exchanger 14 is pressure-reduced by an expansion valve 7 and then evaporated by an evaporator 8 housed in a refrigeration show case. After it is over, the refrigerant is introduced into a compressor 9 and sucked up into a compressor 1 after an increase in both tempoerature and pressure.

Abstract: PROBLEM TO BE SOLVED: To improve the efficiency of a cleaning treatment by providing a cleaning device for executing the removal of deposits of the scaffold plate and erecting frames to be used with dressers arranged above and below so as to execute the cleaning treatment with swiveling blow wheels. SOLUTION: The dresser 17 is kept rotated at a normal speed and the dresser 16 is kept stopped or rotated at a low speed in the case the scaffold plate 1 is subjected to the cleaning treatment. Next, the scaffold plate 1 is advanced while the plate is kept pressed and held by pinch rollers 19a to 19d when the scaffold plate 1 is supplied in the state of rotating feed rollers 18 of a feed mechanism 15. At the time the scaffold plate passes under the dresser 17, the blow is given thereto by the blow wheels 48 and the deposits on the surface are peeled and removed. Next, the dresser 16 is rotated at a normal speed in the case the erecting frame is subjected to the cleaning treatment.  As a result, the outer peripheral surface of the lower half part of the erecting frame is first subjected to the cleaning treatment by the dresser 16 and, thereafter, the outer peripheral surface of the upper half part is subjected to the cleaning treatment by the dresser 17.

IPC: B65G47/24
Filed: 1978-02-18
Abstract: PURPOSE: To prevent damage of contents by inverting boxes while covering their opening, then gradually opening the uncovering to gradually discharge the content, and reducing the drop head of the content.  
     CONSTITUTION: Feed-in conveyors 5 feed boxes 3 into a box inverter 1 from at least two directions. The box 3 is fed onto an elevator 41, with its opening faced up. When the elevator 41 is elevated so that the opening of the box 3 is pushed against, and covered by, the lower transfer surface of a transfer conveyor 23, nipper tables 51 nip the box 3 from both sides. After the box 3 is inverted (the opening is faced down) by a 180° rotation of the conveyor 23, the nipping is released. When the conveyor 23 rotates in the direct on of the arrow, the box 3 passes through the gap slowly, with the opening faced down; at the same time, the content 11 falls at the gap and rolls down along a guide plate 73 onto a conveyor 9 to be carried out. The box 3 is carried out by a conveyor 13.

Title: Method for changing connection of optical fiber and connector
Inventor: TAMAKI YASUHIRO
IPC: G02B26/08
Filed: 1987-01-28
Abstract: PURPOSE:To shorten the time for changing a transmission path by replacing ferrules of 2nd and 3rd optical fibers by the single action to move the ferrules in parallel by utilizing a shallow V-groove in the lower half part of a connector body. CONSTITUTION:The replacement of the 2nd ferrule 21 with the 3rd ferrule 31 is instantaneously executed by the single action consisting in moving the 3rd ferrule 31 in the direction orthogonal with the axial line to press the same to the side face of the 2nd ferrule 21, pushing the 2nd ferrule 21 out of the V-groove 66 in the lower half part 62 of the connector body and putting the 3rd ferrule 31 itself into the V-groove 66. The time when the connection is actually interrupted, is therefore, only the moment of said replacement. The 1st optical fiber and the 3rd optical fiber are connected from the moment when the 3rd ferrule 31 is housed into the V-groove 66 in the lower half part 62 of the connector body. The change of the connection ends when a leaf spring 80 is fitted to the connector. The time when the transmission is infeasible is thereby shortened.

IPC: H04B1/69
Filed: 1993-01-08
Abstract: PURPOSE:To make spread spectrum communication possible whose communication quality is improved by setting an optimum modulation index between transmission and reception. CONSTITUTION:First, transmission data are inputted to a data modulation circuit 1a or the data modulation circuit 1b, data modulation with the different modulation indexes is performed and an amplitude value to be set is varied. The amplitude to be set is decided by the modulation index required for FSK executed to PN clocks by the frequency modulation characteristics of a voltage controlled oscillator and when the amplitude is made large, frequency shift becomes large and the modulation index becomes large. At a switching control circuit 2, one of the signals of the output of the data modulation circuit 1a or the data modulation circuit 1b is selected and outputted by switching control signals. A PN signal generator 3 is driven by the PN clock which is the output of the switching control circuit 2 and PN signals are generated. The PN signals are multiplied by the output of a local oscillator 5 and outputted as carrier waves.
