Title: Antifreezing device of pneumatic valve
Inventor: YANO TOSHIO
IPC: F16K24/00
Filed: 1981-02-07
Abstract: PURPOSE:To prevent a freeze of water in the inside of a valve cage, by causing circulation of water that flows into a receiving port to pass through a communication passage and the inside of the valve cage and return again to the inside of a feed water pipe. CONSTITUTION:Flowing energy of a water stream 12 is applied to a receiving port 11 to increase its pressure, accordingly this causes circulation 13 of water that flows into the receiving port 11 to pass through a communication passage 10, inside of a valve cage 2 and inlet 14 then reach again the inside of a feed water pipe 8, resulting in the very difficult state of freezing water in the inside of the valve cage 2 and in a branch pipe 9. The reason is such that the feed water pipe 8 is very large in size as compared with a pneumatic valve 1, and the quantity of water in the inside is also very large as compared with the quantity stored in the inside of the valve cage 2, then the water is not easily cooled, thus water temperature is relatively high in the inside of the feed water pipe 8. In this way, effective antifreezing can be performed by injection of water in the inside of the feed water pipe 8 into the inside of the valve cage 2.

Title: Fitting guide jig for solid tire
Inventor: KOTANI HIROTAROU
IPC: B60C25/00
Filed: 1980-02-16
Abstract: PURPOSE: To fit a tire to a rim in a normal state by forming a convex on the peripheral edge of a concave to which the rim material is fit.  
     CONSTITUTION: A tire 51 is depressed by a pressure jig 41 up to the position where the inner diameter of the tire 51 makes contact to the maximum diameter of a jig 31. The tire 51 is contracted in the direction where its inner diameter is reduced by the restoring contraction force caused by its inner diameter expansion and moves downward by itself by being guided by the rotational parabolic surface 81a of a convex 81 which has a taper downward. In this case, the upward warping of the inner diameter is almost corrected by the guiding actuation of the rotational parabolic surface 81a which has the taper downward over all circumferences of the tire and the jig 31 is lifted upward through the convex 81 by the wedge effect caused by the restoring contraction force of the tire 51 which makes contact to a horizontal rest surface. Then the tire fully lifts up the jig 31, is fit to the external concave of a rim material 1 in a normal state, and engages with a revolution stop projection 2 in a normal position.

Filed: 1988-01-28
Abstract: PURPOSE:To efficiently recover the cooling medium by connecting a cooling medium recovery tank to a gas/liquid separator via line shutoff valve. CONSTITUTION:When the recovery switch 32 is turned on, the compressor 2 is started, and an electrical signal is transmitted from a control circuit 7 to a line shutoff valve 11 to attract the needle valve 631 of the line shutoff valve 11 by electrical magnetism away from the valve seat 632. As the line shutoff valve 11 is opened, a gas/liquid separator 4 and a cooling medium recovery tank 15 are mutually connected via a connecting pipe 41, the line shutoff valve 11 and a connecting pipe 43. The liquid cooling medium that has been separated in the gas/liquid separator 4 flows into the recovery tank 15. At this moment, a signal is sent from the control circuit 7 to an expansion valve 5 to limit the cooling medium flow rate. That is, an electric current is supplied to the coil 53 to excite same, and its excited magnetism attracts a plunger 52 toward the stationary iron core 50. As a result, the valve body 57 shifts toward the valve seat 54, and the expansion valve 5 is throttled to such an extent that only the gaseous cooling medium coming from the gas/liquid separator 4 is allowed to pass through.
