Title: Waste heat recoverying heat pump
Inventor: UEHARA YUZURU
IPC: F25B27/02
Filed: 1990-01-19
Abstract: PURPOSE:To improve a heating capability in winter season without extending a cooling water circuit up to an indoor device of a G gas engine driving type heat pump by a method wherein a heat exchanging operation is carried out between the cooling circuit and the heat pump circuit. CONSTITUTION:A cooling circuit 12 is formed in general so as to connect an interior of a gas engine 11 with a hot water-refrigerant heat exchanger 14. Since the heat exchanging capability of the hot water-refrigerant heat exchanger 14 has a certain limitation, a sufficient cooling may not be attained by the cooling circuit 14 and a cooling of the gas engine 11 has a certain trouble, resulting in that a cooling circuit 12 is formed so as to connect the interior of the gas engine 11 with a radiator 13. In this case, after the refrigerant of the refrigerant operating chamber 14a is filled in liquid form, the control valve 31 keeps closed until the over-heating state is attained. Then, the heat exchanging operation is carried out in the hot water-refrigerant heat exchanger 14. Then, as the temperature detected by a temperature sensor 35 is higher than a temperature outputted from the temperature sensor 37, the control means 32 judges that the refrigerant in the refrigerant operating chamber 14a is in its over- heated state and then it opens the control valve 31 and the operating chamber 14a is replaced with the liquid refrigerant.

Abstract: PURPOSE: To electrochemically elute a second metal from a cation exchanging substance by bringing the cation exchanging substance into contact with an electrolyte under the condition of a sufficiently high pH thereby electrochemically eluting a first metal from the cation exchanging substance and bringing the cation exchanging substance into contact with an electrolyte under the condition of a sufficiently low pH. CONSTITUTION: A second metal (example: Li) is electrochemically eluted from a cation exchanging substance in a cation exchanging cell (1) by bringing the cation exchanging substance into contact with an electrolyte [example: a liquid containing Co(NO3 )2 and LiOH] under the condition of a sufficiently high pH (example: pH 11). Then, a first metal (example: Co) is electrochemically eluted from a cation exchanging substance in a cation exchanging cell (1) by bringing the cation exchanging substance into contact with an electrolyte under the condition of a sufficiently low pH (example: pH 2). This method effectively separates, by using an electrochemical ion exchange, metal ions in an aqueous solution (example: waste liquid generated from an operation of a pressurized water nuclear reactor) in which hydroxides have different solubilities.

Then, under the condition that the core 1 is set to forming molds 3 and 4, thermoplastic resin is poured in the space between the core 1 and the forming molds 3 and 4 and then solidified. Then, after being released, the solidified thermoplastic resin tubular body 6 is heated up to the intermediate temperature between the melting points of the core 1 and of the thermoplastic resin, of which the tubular body 6 is made, so as to melt the core 1, resulting in flowing the core 1 through the small holes of the filter 1 outside in order to obtain a tubular body having a filter.

Title: Task termination system
Inventor: HIWATARI SHIGEYUKI
IPC: G06F15/177
Filed: 1987-01-22
Abstract: PURPOSE:To know the release of the global resources of a task and at the same time to reduce overhead by adding a control program to each CPU to release the global resources occupied by the task delivered a termination request. CONSTITUTION:The global resources 31 occupied by a task B are released by a control program 21 of the task B. Thus the program 21 can know the release of the resources 31 of the task B. While a control program 11 is required just to write the 1-bit termination request information into a task control block (TCB) 33 of the task B. At the same time, the program 21 reads the TCB 33 during the task schedule processing and shifts the control to the task termination processing. Thus the overhead can be reduced under such conditions. Then the program 11 knows whether the contents of the TCB 33 are cleared or not during the task schedule processing and therefore knows the release of the resources 31 to reduce the overhead then.

Abstract: PURPOSE: To easily mold a molding material by a compression molding method in which molds made of a shape-memory alloy are used and the shape restorability of the molds is utilized at high temperatures in such a way as to eliminate the need for a large-scale compressor.  
     CONSTITUTION: A compression mold 1 is made up of a plate-like lower mold 2, a "ko"(Japanese:katakana,2533)-shaped upper mold 3, and a cylindrical intermediate mold 4. The lower and upper molds 2 and 3 are usually made of a metal, e.g., Fe, Al, etc., and the intermediate mold 4 is made of a shape-memory alloy, e.g., a Ni-Ti alloy, a Cu-Zn-Al alloy, etc., capable of being expanded when heated to a temperature above its critical temperature. When a molding material 5 is cast into the compression mold 1 and heated to the critical temperature of the intermediate mold 4 in a constant temperature tank, the intermediate mold 4 expands toward the direction of arrow by the shape restorability of the shape-memory alloy to impart compression to the molding material 5. Thus, the molding material 5 is thermally hardened under compression to form a desired molding.

Title: Torque sensor
Inventor: NAKAJIMA HIROSHI
IPC: G01L3/10
Filed: 1984-01-24
Abstract: PURPOSE:To measure static torque and prevent responsibility from deteriorating even during low-speed rotation by fixing two slit plates with a specific extent of deviation, and arranging at least two pairs of light emitting and photodetecting elements so that they shift in phase by a half the pitch of the slit plate. CONSTITUTION:The slit plates 4 and 5 are fixed on a shaft 1 with slit plate fixtures 2 and 3 at a specific interval. Those slit plates 4 and 5 are fixed so that the slit plate 5 deviates from the slit plate 4 by an angle A corresponding to a quarter pitch. Light emitting and photodetecting elements 6 and 7 are arranged across those slit plates 4 and 5 while shifting by an angle B corresponding to a half the pitch of the slit plates 4 and 5. Then when the shift 1 twists to displace the slit 4 clockwise from the slit 5, the transmission quantity of light increases in proportion to the twisting of the shaft 1. Consequently, outputs of photodetecting elements 6B and 7B increase and are compared with an initial value to detect the generated torque.

Title: Packaging container for vacuum blood-collecting tube
Inventor: NISHIKATA HIROKATSU
IPC: B65D30/02
Filed: 1999-01-20
Abstract: PROBLEM TO BE SOLVED: To make preventible evaporation of a sodium citrate aqueous solution in a vacuum blood-collecting tube stored in a container which is sealed again after being opened by setting a fastening part at the vicinity of an opening part of the packaging container and sealing the outside with heat. SOLUTION: The fastening part 11 can be sealed by pressing a projection having a leading end of a larger breadth than a base into a recess having an opening part of a smaller breadth than a deep part. The fastening part 11 is set at the vicinity of an opening part of a packaging container 1 for vacuum blood-collecting tubes. Blood-collecting tubes filled with sodium citrate aqueous solution are stored in the packaging container 1. Then, the outside of the fastening part 11 is sealed straightly with heat at 12, thereby, the packaging container 1 is tightly sealed. In using the vacuum blood-collecting tube, the heat seal 12 is pulled apart to both sides or cut, thereby releasing the tight seal. After the vacuum blood-collecting tubes of a necessary number are taken outside, the fastening part 11 is pressed from both sides, thereby sealing the packaging container 1 again.  The sodium citrate aqueous solution in the vacuum blood-collecting tubes in the packaging container 1 sealed again does not evaporate even approximately three weeks later, so that the tubes can be used for inspection.
