Title: Device for refrigeration cycle
Inventor: SAKAI TAKESHI
IPC: F25B1/00
Filed: 1989-03-31
Abstract: PURPOSE:To efficiently separate a specific refrigerant so as to improve the efficiency of the operation and achieve the operation at high temperatures by providing a first part of line wherein a specific refrigerant is adsorbed, a second part of line whereby refrigerant is returned to a refrigeration cycle line, a third part of line whereby the refrigerant is released from the adsorption, a directional control valve for shifting between the first and the third parts of line, and a means for storing the refrigerant released from the adsorption. CONSTITUTION:From a mixture of refrigerants in a gasified highly pressurized state fed in a flow to a gas feed inlet 12 of an adsorption tower 11, R-114 is preferentially adsorbed by activated alumina 15; the refrigerant consisting mainly of R-22, which passes through the activated alumina 15 without being adsorbed, is piped back by return pipes 22 to the low temperature side in a refrigeration-cycle line 1. After continuation of this adsorption process for a certain period of time, a command from a control unit 31 causes a directional control valve 16 to shift to the connection between the adsorption tower 11 and a storage tank 20. Then the activated alumina 15 is depressurized and the refrigerant consisting mainly of R-114, which has been under adsorption, is released from the activated alumina 15 and stored in a storage tank 20.

Title: Heat fixing device
Inventor: SOGA SETSUO
IPC: H05B3/00
Filed: 1982-05-18
Abstract: PURPOSE:To shorten the temperature rise time and to suppress the temperature of a heating conductor to a relatively low temperature, by forming a cylindrical core consisting of a superheat-resistive polyimide, a resistance layer which is provided on the outside surface of this core and heats by feed, and an offset preventing film on the outside surface of this resistance layer. CONSTITUTION:The temperature of the outside surface of an offset preventing film 3 is held at a prescribed temperature higher by heating of a resistance layer 2; and when a toner supporting material has a toner placed on the side of the offset preventing film 3 and is inserted in the state where a core 1, the resistance layer 2, the offset preventing film 3, and a pressure roller are rotated, the toner is melted by heat and is pressurized and is fixed to the toner supporting material. In this case, the core 1 can be made thin because the core 1 is formed with a superheat-resistive polyimide and has high strength for load, and the heat capacity can be made small because the offset preventing film 3 is formed directly on the outside surface of the resistance layer 2; and therefore, the temperature rise time from the start of feed to the resistance layer 2 to the attainment to a desired temperature is shortened, and it is unnecessary that the temperature of the resistance layer 2 is made considerably higher than that of the offset preventing film 3.

IPC: B21B1/26
Filed: 1985-04-19
Abstract: PURPOSE:To cut economically rolling materials without installing a cutting installation by detecting the joint part between the preceding rolling material and the succeeding rolling material from the change of the rolling load in a final stand of a finishing mill and increasing the outlet side tension of the final stand. CONSTITUTION:A load cell 3 detects an abrupt load increase when the joint part 11 between the preceding rolling material 1a and the succeeding rolling material 1b arrives at the final finishing stand 21. The detected value exceeds the set value of a control device 4 and therefore a command for a tension increase is emitted to a coiler 5. The prescribed over-tension is thereby exerted to the material 1 and the joint part 11 is ruptured. The disconnected material 1a is straightly coiled on the coiler 5 and the succeeding 1b is straightly coiled by another coiler 6 under standing-by by table rollers. Since the cutting is executed in the above-mentioend manner without installing the cutting machine, the economical effect is high.

Title: Pcm voice transmission equipment
Inventor: TAKASO KAZUTO
IPC: H04B14/04
Filed: 1988-04-06
Abstract: PURPOSE:To suppress undesired voice properly and to improve the quality of talking by using a delay means provided on a position prestage to a mute circuit if any synchronizing signal is detected consecutively for the prescribed number of times by a synchronization detection means so as to retard a received PCM voice signal or an analog voice signal. CONSTITUTION:If out-of-synchronism takes place due to the deterioration in a transmission line and a synchronizing signal error FAS' is detected twice consecutively, a synchronizing signal detection and protection section 5 transfers to the forward protrusion state F2 from a synchronization establishing state S. Then a mute circuit section 4 starts the muting at this point of time to inhibit the transmission of the succeeding reception PCM voice signal. In such a case, the reception PCM voice signal is retarded by 2 period of the synchronizing signal FAS by the signal delay section 3 at the prestage of the mute circuit section 4. Thus, before the mute circuit section 4 starts the muting, the undesired voice due to out of synchronism passes through the mute circuit section 4 and is not supplied to a digital analog conversion section 2, resulting that the output of the undesired voice is surely prevented.

Title: Four-wheel drive device
Inventor: HIRAIWA KAZUMI
IPC: B60K17/348
Filed: 1986-04-15
Abstract: PURPOSE:To make front-wheel torque controllable by constituting a four-wheel drive vehicle in a way of installing a transfer torque controllable hydraulic clutch in one side of driving routes between a front wheel differential gear and symmetrical front wheels, in case of the 4WD vehicle mounted with an engine horizontally in the car front. CONSTITUTION:If hydraulic pressure acting on a hydraulic clutch 44 is set to zero and a clutch 44 is released, there is no torque transfer to the side of a right front wheel 48. When the side of the right front wheel 48 comes into a state of being raced, there is also no torque transfer to the side of a left front wheel 42 by action of a front wheel differential gear 14, whereby the torque transfer to both symmetrical front wheels 48 and 42 is brought to nothing. Therefore, all torque is transmitted to a rear-wheel differential gear 30 through a transfer 16, coming to 100% rear-wheel drive. In addition, if sufficient high pressure is made to act on the hydraulic clutch 44, front and rear wheels all are driven at the same rotational speed. With this constitution, driving torque for front wheels are made controllable.
