Title: Gas circuit breaker
Inventor: KANEMAN NAOHIRO
IPC: H01H33/985
Filed: 1993-03-31
Abstract: PURPOSE:To obtain stable circuit breaking performance, and concurrently lengthen the life of a contact by subsequently forming a possible circuit breaking area by a thermal puffer before a possible circuit breaking area by magnetic arc drive comes to a critical value. CONSTITUTION:During the moving process of a movable contact 5 before a possible circuit breaking area A by magnetic arc drive comes to a critical value, the parts of both the areas A and B are overlapped so that a possible circuit breaking area B by a thermal puffer is started. This overlapping thereby allows the contact 5 to get out of the opening of a nozzle 4 for setting the position or the shape of the nozzle 4, before the possible circuit breaking area A comes to a critical value. This setting eliminates an impossible circuit breaking area where no circuit breaking takes place, out of a possible circuit breaking area C in the way of a process for dissociating the contact 5. Therefore, the whole length of the continuous area C becomes long, and stable circuit breaking performance can be obtained, so that a continuous circuit breaking area required as a circuit breaker for the area where arcing time is short, can thereby be secured.

Filed: 1987-03-30
Abstract: PURPOSE:To suppress the sliding friction among lines by forming a couple of pipe type transmission lines and an axial transmission line in a straight line and connecting adjacent axial transmission lines by a pate shaped transmission line having an elasticity. CONSTITUTION:In operating a drive section 8, a mobile body 5 is moved to move the axial transmission lines 3a, 3b via mount parts 5a, 5b. Thus, if the length of the transmission line comprising stationary pipe transmission lines 2a, 2b and the axial transmission lines 3a, 3b is changed, the phase of an electric signal between input/output connectors 1a, 1b is changed to retard the signal. Moreover, in changing the moving quantity of the drive section 8, the delay quantity of the electric signal is changed consecutively and in providing plural pipe type transmission lines 2a-2d and plural axial transmission line 3a-3d, the delay quantity is increased. The entire transmission line is prolonged to increase the delay and oven if the sliding parts are increased in number, the movable transmission line is slided lightly with respect to the stationary transmission line.

Abstract: PURPOSE:To eliminate the detection error due to nonreproducibility or the like and to improve detection precision by fixing not only a vibrating body but also a cylinder in the vibrating body to a supporting base and attaching a driving coil and a pickup coil to this cylinder. CONSTITUTION:A cylinder 11, a driving coil 12, a pickup coil 13, etc. are provided. When a vibrating body 10 fixed to a supporting base 2 receives pressure at an inside through a pressure port 3, stress is generated in the oscillating body 10 by the pressure difference between the inside and the outside of the vibrating body 10 and the spring constant of the vibrating body 10 is changed in accordance with this stress generation to change the intrinsic frequency of vibration. Since the intrinsic frequency of vibration of the vibrating body 10 is proportional to the pressure, the vibrating body is vibrated by the coil 12 and the intrinsic frequency of vibration of the vibrating body 10 is detected by the coil 13 to detect the pressure. The intrinsic frequency of vibration detected by the coil 13 is led to an electronic circuit 4 by a lead wire 6b and is processed in a circuit 4 and is outputted as a digital signal form a connector 5.
