Abstract: A piezoelectric oscillator is provided, which has a through electrode providing reliable conduction between a piezoelectric vibrating piece and an external electrode with rare occurrence of a large stress caused by temperature variation in processing or deformation of a mounted base substrate, while the hermeticity of a cavity is maintained. A piezoelectric oscillator having a piezoelectric vibrating piece sealed in a cavity defined between a base substrate and a lid substrate includes a through electrode disposed in a through hole penetrating through the base substrate, and the through electrode has a glass frit filled in the through hole and fired and a core formed of a material containing only iron and nickel and disposed in the through hole together with the glass frit. The values of the thermal expansion coefficients of the base substrate, the glass frit, and the core are set as: base substrate glass?frit>core.

Abstract: A piezoelectric vibrator has a vibrator piece and a frame integral with the vibrator piece. The frame is connected to one end of and surrounds the vibrator piece. A lid has a surface anodically bonded to a first surface of the frame. The lid has a recessed portion at a position disposed opposite to and confronting the vibrator piece. A base has a surface anodically bonded to a second surface of the frame opposite the first surface thereof. The base has a recessed portion at a position disposed opposite to and confronting the vibrator piece. A beveled portion is formed around a surface of one of the lid and the base which does not correspond to the anodically bonded surface thereof.

Abstract: The present invention provides a piezoelectric vibrator which can sufficiently minimize the fluctuation of the oscillation frequency or the resonance resistance value even when a large static external force is applied to a package of the piezoelectric vibrator, a manufacturing method thereof, and an oscillator and an electronic equipment provided with the piezoelectric vibrator.

Abstract: A lyophilized preparation which releases a fat emulsion, wherein the emulsion particle has a mean diameter of 10 to 100 nm, when redissolved prior to use. This preparation is produced by adding maltose in an arbitrary stage of the production of said emulsion prior to lyophilization.

Abstract: Stable homogeneous fatty emulsions containing amphotericin B are prepared. According to one embodiment, amphotericin B is decrystallized using an acid and ethanol and then homogeneously dispersed in a lipid, following which it is emulsified.According to a second embodiment, amphotericin B crystals are kneaded until their presence can no longer be confirmed and the decrystallized amphotericin B is thereafter uniformly dispersed in a lipid and, thereafter, emulsified.

Abstract: A rotary vane compressor comprises a cylinder having two closed ends defining a cylinder chamber in which is rotatably mounted a rotor. The rotor carries a plurality of radially movable vanes which move radially into sliding contact with the inner surface of the cylinder chamber during rotation of the rotor to compress a refrigerant gas. The rotor is rotationally driven by a rotor shaft rotatably mounted by bearings in the cylinder ends. To prevent destruction of the ozone layer, a refrigerant containing no chlorine, such as HFC-134a (1,1,1,2-tetrafluoroethane; CH.sub.2 FCF.sub.3) is used, and to compensate for the inferior lubricating properties of the chlorine-free refrigerant, the bearings are provided with a manganese phosphate coating of 10 .mu.m-15 .mu.m thickness to prevent cohesion and seizure of the mutually contacting surfaces of the bearings and rotor shaft.

Abstract: A roundness processing device for a slipper surface of a rocker arm capable of rounding the slipper surface of the rocker arm without forming roundness on the polishing surface of a grinding wheel. A wheel side unit containing a disc-shaped grinding wheel, a jig side unit for holding and oscillating the rocker arm, a conveyor for conveying the rocker arm, and an access robot for moving in and out the rocker arm are automatically driven and controlled, as being mutually related, by automatic control such as numerical control. The polishing surface of the grinding wheel is formed on a plane vertical to the rotary shaft line of the grinding wheel, while the slipper surface of the rocker arm is oscillated about the oscillation shaft line positioned at a distance of a specific radius of curvature from the polishing surface.

Abstract: Liposomes of steryl glucosides and/or steryl glucoside monopalmitates are useful for hemostatic, vascular stabilization and anti-shock effects, particularly in the form of injectable solutions.
