Title: Packing and switching device using the same
Inventor: KATSUMATA KIYOHITO
IPC: H02B1/28
Filed: 1999-05-10
Abstract: PROBLEM TO BE SOLVED: To improve watertightness by gluing a reinforcing member to the outer-periphery surface of a side where pressure due to packing increases. SOLUTION: An arc part 21 and a plane part 22 located at both the sides of the arc part 21 are formed on the outer-periphery surface of a main packing 18a being located outside a monitoring window. A cross sectional shape adheres to the main packing 18a of an arc-shaped reinforcing member 23 so that the outer-periphery surface of the arc part 21 can be covered. When pressure in the monitoring window decreases below the outside pressure, the reinforcing member 23 is pressed, thus preventing watertightness from being lost due to the deformation of the packing caused by the pressure difference between the inside and outside.

Abstract: PURPOSE:To secure the synchronization of time among plural devices based on the time of another device even if the reference time given from a master device is interrupted by providing the function of the master device to a precedent device and shifting the master function to another normal device when the master device has a fault. CONSTITUTION:A master device is defined among plural devices 12 such as a facsimile, a switchboard, a display device, etc., which contain the information processing functions and are connected to a data highway 11 serving as a data transmission line. Then the time of a clock circuit 14 of each device 12 except the master one is synchronous with the reference time of the circuit 14 of the master device 12. When the reference time of the master device 12 has a big error to the average time of other devices 12, a wrong reference time is decided and then corrected to the average time. If the master device 12 has a trouble, another normal devices 12 substitutes for the faulty master device. As a result, the synchronization of time is always secured among the circuits 14 of devices 12.

Filed: 1999-05-10
Abstract: PROBLEM TO BE SOLVED: To delay the flow of the air from an air chamber by increasing the repair effect of a stab by a seal agent, in a tire containing the seal agent. SOLUTION: In this tire, an outside liner 2 is adhered on the inner surface of a tread 4 and a seal agent chamber 7 filled with a seal agent 6 between this outside liner 2 and the inside liner 3 is partitioned and also an air chamber 8 filled with the air inside the inside liner 3 is partitioned. By constituting the inside liner 3 by a soft rubber whose 300% modulus is 60 kgf/cm2 or less, the stab 31 itself of the inside liner 3 produced by a nail N is not only shrunk, but also the stab 31 is shrunk quickly after the nail N is removed and the flow out of the air from the air chamber 8 can be delayed. As the soft inside liner 3 can be deformed easily by the air pressure in the air chamber 8, the seal agent 6 in the seal agent chamber 7 is pushed out quickly into the stab 41 of the tread 4 by the air pressure and the stab 41 can be repaired effectively.
