Title: Fluid vibration detecting device
IPC: G01F1/20
Filed: 1992-03-17
Abstract: PURPOSE:To improve the S/N of output signals by preventing the generation of noise from a piezo-electric film even when external vibrations are applied to the film. CONSTITUTION:Since electrodes 22-24 are formed on both surfaces of a piezo-electric film 21 except its outer peripheral section sandwiched by compression between an upper and lower housings 15 and 27, any voltage generated across the sandwiched section of the film 21 is not collected to the electrodes 22-24 even when the inertial forces of the housings 15 and 27 press the sandwiched section against each other. Therefore, the output of noise caused by external vibrations can be reduced and the S/N of output signals can be improved.

Filed: 1978-07-27
Abstract: PURPOSE: To provide ferrimagnetic garnet whose ferromagnetic resonance absorbing half power width ΔH can be reduced by using benzene or trichloroethylene in mixing and pulverizing Ca, V, and Fe.  
     CONSTITUTION: Resonance absorbing half power width ΔH of a sintered article, as is well known, varies according to the density and particle size of the article and presence or absence of heterogeneous phase in the article and depends on saturation magnetization value, magnetic anistropy constant, and vacancy rate. The saturation magnetization value and the anistropy constant are determined by the composition of the garnet product, while the vacancy rate depends on a method of making the product. In the present method, a mixture of V 2 O 3 , CaCO 3 , Fe 2 O 3 , In 2 O 3 , and V 2 O 5  as raw material and benzene or trichloroethylene as dispersing agent are mixed together, the mixing ratio of the raw material and the dispersing agent being from 0.5 to 10. The resultant mixture is provisionally sintered and pulverized, followed by re-mixing and press-molding. The molded product is then subjected to sintering to yeidl (Y 2.3 Ca 0.7 )(Fe 1.45 In 0.55 )(Fe 2.65 V 0.35 O 12 . The multicrystalline garnet thus produced is given a high density and characterized by great reduction in its half power width of resonance absorption and also in apparatus losses.
