Filed: 1989-04-11
Abstract: PURPOSE:To prevent sealing liquid from leaking owing to external vibration and an external shock by charging magnetic liquid in a pressure transmission pipe and arranging magnets for holding the magnetic liquid outside the transmission pipe. CONSTITUTION:A semiconductor pressure sensor 2 is held by a base material 3, which is fitted to a substrate 4. The magnetic liquid 11 which uses fluorine- contained oil as its base is charged in the pressure transmission pipe 10 connected to the substrate 4. The permanent magnets 12 and 13 are set outside the pressure transmission pipe 10 so that their opposite surfaces become opposite magnetic poles.

Title: Vibrating type compressor
Inventor: TAKAHASHI TAKAHIRO
IPC: F04B17/04
Filed: 1984-05-08
Abstract: PURPOSE:To check the excessive displacement of a piston and reduce an impact noise as well as to prevent any damage to a valve from occurring, by installing such a spring as being compressed only just before the piston collides with a discharge valve, in a state of being compressed by a holding plate. CONSTITUTION:When a piston 9 reaches the vicinity of a discharge valve 19 by dint of solenoid-operated force, a collision piece 23 collides with a compression spring 16 via a cap 15 just before the piston 9 bumps against the discharge valve 19, reducing a speed of the piston 9 to some extent. In combination with this, strong repulsive force of the compression spring 16 being so far held in a state of being compressed by a holding plate 14 via the cap 15 will sharply reduce the impact force between the piston 9 and the discharge valve 19. With this constitution, a noise to be produced by the impact between the piston 9 and the discharge valve 19 is well reduced and, what is more, any damage to the valve can be prevented from occurring.
