Title: Gas cock
Inventor: SAITO CHOJI
IPC: F16K35/06
Filed: 1998-03-25
Abstract: PROBLEM TO BE SOLVED: To reduce the number of components in rotation regulation and locking mechanism and save the labor of machining in a gas cock capable of being rotationally regulated and locked. SOLUTION: An upper radius edge 4 and a lower radius edge 5 having an internal diameter 5a larger than an internal diameter 4a of the upper radius edge 4a are formed at a cock built-in port 3 of a gas cock body 1, and locking slits 6, 6a are formed in the boundaries. When a small-diameter step 22 is fitted with the lower radius edge 5 by slightly pushing a locking pin 20 in, a handle 13 can be opened and closed; when the locking pin 20 reaches the position of the locking slit 6 or 6a by rotating the handle 13, the locking pin 20 is pushed out so as to accommodate the lower half of a larger-diameter portion 2 at its end side, thereby being locked to close the cock.  When the gas cock is sealingly locked, a screw for sealing 21a of the locking pin 20 is screwed in a screwed hole for sealing in a locking pin built-in bore 17, so that the lower half of a large-diameter portion 23 at the rear end side of the locking pin 20 is accommodated in the locking slit 6 or 6a, so as to sealingly lock the handle 13.

Title: Method for preventing deterioration of heating medium for solar heat utilizing system
Inventor: KIMURA YUKIO
IPC: F24S90/00
Filed: 1987-03-31
Abstract: PURPOSE:To improve th reliability of a solar heat system by causing heating medium in the collector to drain down for returning the same to a heating medium reserve tank by connecting an on-off valve which is open to the atmosphere to a heating medium circulation pipe near the highest position, and causing the valve to be opened while a heating medium pump is not working. CONSTITUTION:A solenoid valve 13 which is open to the atmosphere is connected to a heating medium circulation pipe 6 near to its highest position, i.e. the location of outlet of the collector 1 which is rigged in an inclined position. The solenoid valve 13 is normally closed, and its opening is controlled by a command from a controller 11 while a heating medium pump 4 is not working. When an excessive amount of heat is collected while the system is being operated for solar heat collection, such a condition is sensed by an excessive heat collection sensor 10, which causes the heating medium pump 4 interlocked via the controller 11, and, at the same time, feeds a signal to the solenoid valve 13 to open it. This operation allows the atmosphere to enter the system through the solenoid valve 13, and, at this moment, the heating medium remaining in the collector 1 instantly drains down under gravity without delay in the response time to be discharged out of the collector for recovery into a heating medium reserve tank 5.

Filed: 1986-04-08
Abstract: PURPOSE:To prevent a smoke emitting phenomenon by prohibiting the continuous supply of a current to a heater, by prohibiting the reception of a reset signal from a controller only when the jamming of paper is generated in a recording apparatus. CONSTITUTION:When jamming is generated in a recording apparatus 21, a jamming signal 302 showing a jamming state is supplied to the L-active input terminal of an AND gate 31 from CPU23 and the AND output 303 from the AND gate 31 comes to 'L' and no resetting is performed. Further, the AND output 303 comes to 'H' as far as no jamming is generated and resetting is performed. When a reset signal is inputted to the AND gate 31 inclusive of a reset signal of soft meaning such that a CPRDY signal 201 changes from an 'H'-level showing the controllability of a controller 22 to an 'L'-level showing the non-controllability thereof, it is judged whether jamming is generated in the recording apparatus and, only when it is judged that no jamming is generated, the program counter PC of CPU23 is set to (00) as well as the content of RAM is cleared. Therefore, at the time of jamming, the recording apparatus is held to a non-reset state even if the reset signal is inputted.
