Title: Absorption type water cooler and heater
Inventor: KANEYAMA TAKASHI
IPC: F25B15/14
Filed: 1990-04-28
Abstract: PURPOSE:To eliminate the need for a heating facility when separating refrigerant by providing an absorber, which collects refrigerant vapor into a sprayed suction solution, a pump, which boosts pressure to said suction solution, a regenerator which separates refrigerant from the suction solution, and a cooler, which cools the refriger ant. CONSTITUTION:An absorber 4 is provided with a suction solution spray pipe 41, which sprays a suction solution, such as aqueous solution of LiBr and a cooling pipe 42, which eliminates suction heat generated when the suction solution absorbs the vapor of refrigerant where it is possible to maintain a constant vapor pressure generated in a vacuum vessel 1 and vaporize in continuous mode by absorbing the vapor of the refrigerant generated in a vaporizer 3 into the suction solution. On the other hand, a reverse osmosis film unit 82 of a regenerator 8, which is laid out outside a vacuum vessel 1, is built in with a reverse osmosis film so that only the refrigerant absorbed in the suction solution may be extracted on the opposite side of the reverse osmosis film 83 by boosting up the suction solution into which refrigerant is absorbed higher than the reverse osmosis pressure of refrigerant by driving a pump 81. Since this refrigerant is heated to a higher temperature by the pressure application, the refrigerant can be returned to the vaporizer 3 by way of a refrigerant spray pipe 32 after having cooled the refrigerant by a cooling pipe 91.

Title: Tensile tester for tubular test piece
Inventor: KOIZUMI CHIKAHIDE
IPC: G01N3/04
Filed: 1990-04-27
Abstract: PURPOSE:To automatically mount and detach a core metal and to achieve the simplification and cost reduction of an apparatus by mounting a metal pad to a core metal main body part in a flange shape in a slidable manner and restricting the movement of the metal pad in a load shaft direction by a crosshead. CONSTITUTION:Core metals 30 are inserted in both end parts of a tubular test piece TP by a core metal mounting and detaching mechanism 20 and both ends of the tubular test piece TP are grasped by opening and closing type grasping jigs 18. After the test piece TP is subjected to a tensile test by a load means 12, the core metals 30 are pulled out of the tubular test piece TP by the core metal mounting and detaching mechanism 20. At this time, the tubular test piece TD is also driven together with the core metals 30 but, since the end surface of the tubular test piece TP is hooked with the metal pad 33 whose movement in a load shaft direction is restricted by crossheads 16, 17, only the metal pad 33 is pulled out. Since the metal pad 33 is mounted on a core metal main body part 31 in a flange shape regardless of the outer diameters of the core metals 30, the core metals having any outer diameter can be pulled out by the core metal mounting and detaching mechanism 20 without providing a special device.

IPC: G06F11/30
Filed: 1982-06-30
Abstract: PURPOSE:To reduce a load on a central processor and to control timing without reference to the number of devices which controls the timing, by allowing a timing queue and a time-out pointer to perform all timing monitoring in a bundle. CONSTITUTION:When an event occurs to one resource RSi and a control part CTL detects the timing monitoring is being required, the control part CTL sends the equipment item number of the resource RSi (=i), time information on the timing monitoring, and a request for the timing monitoring to a timing monitoring accepting part SPR. The timing monitoring part SPR links a timing buffer TBi to the timing queue so that a time-out state is detected a monitoring time (t) after the present point of time on the basis of the time information to be monitored. Thus, the monitor processing is realized regardless of the number of resources, by checking the timing buffer TBi and updating the time-out pointer TP.

Title: Radio equipment with antenna mount frame
Inventor: SUEMITSU GORO
IPC: H01Q1/12
Filed: 1992-05-06
Abstract: PURPOSE:To facilitate periodical maintenance of the radio equipment and to secure the positioning between the antenna and a conical horn by forming the antenna and the radio equipment with the conical horn as two sets separately and mounting them to a mount frame respectively independently. CONSTITUTION:An antenna 2 is mounted to an antenna mount 6 of a mount frame 5 through a mount hole 9.

Moreover, the conical horn 3 is mounted by using a guide hole 8 made to the antenna mount 6. At the periodic maintenance, it is possible to release and remove only the radio equipment 1. Thus, since the antenna 2 whose directivity adjustment is finished is fixed as it is to the mount frame 5, it is not required for re-adjustment different from a conventional radio equipment.

Title: Disk centering mechanism
Inventor: MUKAI KATSUHIKO
IPC: G11B17/12
Filed: 1992-05-06
Abstract: PURPOSE:To prevent the wear of an opening part disposed in a disk centering mechanism coming into contact with the shaft of a disk device side by forming the opening part with using a position matching member of lower hardness than the shaft. CONSTITUTION:The guiding opening part 11 of an armature down 6 is formed larger than a regulative opening part 10 formed by an armture upper 5. A spindle shaft 8 is inserted into a disk 1 through the opening part and the disk is rotated by a spindle motor 9. The hardness of the shaft is set as 58 to 62 HRC and the hardness of the armature upper 6 and the down 6 are set as 52 to 56 HRC by heat treating or Ti coating. Consequently, even when the opening parts 10 and 11 are brought into contact with the shaft at the time of loading/unloading, the opening parts are hardly worn, then the deviation of centering is reduced. When the hardness of the armature upper 5 and the down 6 is set 2 to 10 HRC lower than the hardness of the shaft 8, the durability of the disk device is more superior than the disk centering mechanism. Also, a taper is formed at an abutting part of the shaft with a position matching member and lubricating agent is applied on the contact surface, then the wear is prevented.
