Title: Surface acoustic wave filter device
Inventor: SUGIYAMA MASAHIKO
IPC: H03H9/64
Filed: 1994-12-12
Abstract: PURPOSE:To reduce a warped substrate and spurious radiation of a bulk wave by adopting a mirror polished surface for both sides of as piezoelectric substrate and connecting plural stages of transducers in cascade. CONSTITUTION:A mirror polished surface to the same degree of polish processing as that of a front side of a piezoelectric substrate 10 with transducers 13-16 formed thereon is applied to a rear side of the substrate 10. A 1st filter stage 11 provided with a sender side transducer 13 and a receiver side transducer 14 and a 2nd filter stage 12 provided with a sender side transducer 15 and a receiver side transducer 16 are formed on said substrate 10, and a signal filtered by the filter stage 11 is fed to the filter stage 12, in which filtering is executed twice. Through the constitution above, production of a contraction force caused in the substrate 10 is prevented and the transducers 13-16 are formed in the flat surface without a bent. Since the obtained attenuation characteristic is a product of the attenuation characteristics of the filter stages 11, 12, sprious radiation of a bulk wave is remarkably reduced. Thus, the yield at the time of manufacture is much more improved.

Title: Needle for medical treatment
Inventor: SAITO MASATAKA
IPC: A61M5/158
Filed: 1990-11-15
Abstract: PURPOSE:To assure safety by providing a metastable position and stable position in the position where the tip of a needle tube is covered and limiting the rotation of a cover member around the longitudinal direction of the needle tube to a cover member which cannot move from the stable position to the other position once this member enters the stable position. CONSTITUTION:The needle part 20 of the wing-shaped needle and the cover member 30 forms the metastable position and the stable position according to the correlative positions thereof. The cover member has some resistance when a person tends to move the member from the metastable position but the resistance at the time returning the member is conversely low. Then, the person feels the metastable position as if this state is stable. When the member transfers from the metastable position to the stable state through inclined parts 26, 27, the member is locked there and cannot return. The rotation of the cover member 30 around a supporting and connecting member 22 is limited and the handling operation in the handling of the needle for medical treatments after use is stable. The safety is assured in this way.
