Title: Production of heat storage material capsule
Inventor: SAITO TOMONARI
IPC: D01D5/36
Filed: 1987-06-12
Abstract: PURPOSE:To produce the title capsules having a large surface area per unit wt., by continuously extruding a soln. of a hollow fiber membrane-forming polymer in an org. solvent from the outer orifice of a hollow annular nozzle while intermittently extruding a latent heat storage material from the inner orifice of the nozzle, followed by coagulation. CONSTITUTION:5-60wt.% hollow fiber membrane-forming polymer (e.g., PS) is dissolved in a good org. solvent (e.g., benzene) to prepare a soln., which is then fed into a tank 3 and thereafter through a feed inlet 4 into a hollow annular nozzle 5. The soln. is then continuously extruded into a poor org. solvent 14 (e.g., petroleum ether) from the outer spinning orifice 11 of the nozzle 5. Simultaneously, a molten latent heat storage material (e.g., sodium acetate trihydrate) is fed into a tank 7 provided in a thermostatic chamber 6 and then intermittently extruded into the solvent 14 from the inner spinning orifice 12 of the nozzle 5 through a feed inlet 10 with the aid of air 9 having a pressure controlled by a pressure control valve 8 and intermittently fed into the tank 7 by opening or shutting a valve 18. The polymer undergoes phase separation to produce a capsular product 13 having a capsular wall 15 filled with the heat storage material 16. Subsequently, the capsular product is cut off at a constriction 17 thereof.

Title: Tape recorder
Inventor: TAKAGAKI JIYUNICHI
IPC: G11B15/02
Filed: 1982-08-24
Abstract: PURPOSE:To ensure the correspondence to the state of the other track side, by using a head for another track to detect the presence or absence of the record at the other track side during the record (reproduction) of a track of at least a double track tape. CONSTITUTION:In the case of the forward reproduction or record, the signal if recorded on a track of reverse direction is detected by a signal detecting circuit 14. Then an FF15 is set. An H signal is supplied to a terminal 16 for a prescribed period of time when a tape end detecting device is actuated. At the same time, the H signal is supplied to a terminal 17 when a reciprocating switch is operated. The L and H signals are supplied to a terminal 18 in record and reproduction mode respectively. As a result, it is avoided that the recorded side of a tape is mistakenly erased when the other side is recorded. Furthermore the reciprocating reproduction is automatically stopped when the other side of the tape is not recorded at the tape end. This prevents the useless reproduction in the opposite side. Thus a double channel tape is applicable to a record/reproduction head, and therefore, the crosstalk is improved in the record and reproduction modes.

Abstract: PURPOSE:To make the substrate preparation and circuit packaging of a microwave balanced modulator easier and, at the same time, to reduce the cost of the modulator, by constituting all the transmission circuits constituting the modulator on one surface of a dielectric substrate together with micro-strip lines. CONSTITUTION:On the surface of a dielectric substrate 100, all the transmission circuits, such as the-1st 4th strip conductors 1-4 used as micro-strip lines, a strip-shaped dielectric base plate 5, the 1st and 2nd diodes 61 and 62, etc., which are required by this device are constituted. An inputted carrier P1 of a microwave is opposite-phase distributed to conductors 2 and 3 through a conductor 1 and the base plate 5 and offset by a conductor 4. Thus a balanced state is maintained. When a modulation signal P3 is inputted, the diodes 61 and 62 are turned on/off in accordance with the sign (positive or negative) of the input pulse and a modulated signal P2 is outputted. When all the transmission circuits are constituted on one surface of the base plate 100 in such way, the substrate preparation and circuit packaging become easier and the cost can be lowered.

Filed: 1993-06-17
Abstract: PURPOSE:To relieve the load of position registration processing with respect to an exchange by stopping the processing of position registration during other optional setting then it is discriminated that a mobile set is moving at a high speed thereby reducing the traffic. CONSTITUTION:This exchange is provided with a mobile terminal equipment 1 and radio base stations 2a-2d form speech zones 3a-3d respectively. Then each of the radio base stations 2a-2d sends intermittently a position registration start signal including a zone ID allocated specifically to the mobile terminal equipment. Then an exchange 4 accommodates the radio base stations 2a-2d to control the radio base stations 2-2d and the mobile terminal equipment 1. When the terminal equipment detects high speed moving, the terminal equipment stops the usual position registration request and does not send the position registration request signal to the exchange till no high speed moving is detected. In the case of exchange for an incoming call, a registration part of a table corresponding to each terminal equipment for high speed moving is referenced and when high speed moving is registered, it is informed to a caller.
