Filed: 1994-02-25
Abstract: PURPOSE:To obtain a low and thin ladder filter by constituting the filter by combining a piezoelectric resonator operating by a spreading vibration mode and the piezoelectric resonator operating by a length vibration mode. CONSTITUTION:This filter is composed of piezoelectric resonators 21 to 24, an input terminal 25, an output terminal 26, a repeating terminal 27, an earth terminal 28, an inner case 30 and an outer case 31. The piezoelectric resonators 21 and 22 are formed into a rectangular shape, electrodes are formed with silver on the surface and back faces, the resonators operate by a length vibration mode and they are serially connected. The piezoelectric resonators 23 and 24 are formed into a planar shape, electrodes are formed with silver on the surface and back faces, the resonators operate by a spreading vibration mode and they are connected in parallel. Thus, because only two sheets of the piezoelectric resonators 23 and 24 are piled in the thickness direction and the piezoelectric resonators 21 and 22 are arranged on the side of the resonators 23 and 24, this filter becomes thin, and the height is roughly half as compared with a normal ladder, filter, and the resonators 21 and 22 do not occury much area.

Title: Ball passage blocking type vibration reducer
Inventor: KANOU IWAO
IPC: F16F7/10
Filed: 1982-02-26
Abstract: PURPOSE:To restrict a relative movement between two members by a method wherein a ball nut and an inertia ring interposed between said two members are communicated and connected with each other by a circulation path of a ball, and this circultion path is intercepted when the sudden relative movement is generated between the two members. CONSTITUTION:One of two catches 1a and 2a is connected to a piping, and the other to a structure. When a slow displacement takes place in the piping and a relative movement occurs between the two catches 1a and 2a, a ball nut 3 rotates and an inertia ring is also rotated together with the ball by the action of a spring 9. On the occasion, a circulation path of the ball 4 is left communicated, and thus said rotation goes without resistance. When a sudden vibration occurs in the piping, the ball nut 3 makes a sudden reciprocating rotation, while the spring 9 is bent by the static inertia of the inertia ring 6. Thereby an angular phase difference is caused between the ball nut 3 and the inertia ring 6, the circulation path of the ball is intercepted, and thus an action of reducing the vibration takes place.
