An oscillatory gyroscope having an improved detecting sensitivity. The oscillatory gyroscope includes an elastic metal body in the form of a rectangular column having first to fourth surfaces. The elastic metal body includes a distal portion having a distal through hole extending from the second surface to the fourth surface and a proximal portion having a second through hole extending from the first surface to the third surface. Two first ferroelectric substance films are provided on the first and third surfaces in the distal portion. Two second ferroelectric substance films are provided over the second and fourth surfaces in the proximal portion. First and second electrodes are provided on each of the first ferroelectric substance films, and third and fourth electrodes are provided on the respective second ferroelectric substance films. Voltages of reverse polarities are applied to the first and second electrodes. The positions of the first and second electrodes on the first surface are reversed with respect to those of the third surface.

A catheter includes a longitudinally extending catheter tube to be inserted into a body. A plurality of sensing portions are arranged in the catheter tube for detecting at least two types of pressures acting on the catheter when inserted into the body. Each sensing portion is arranged along the longitudinal direction of the catheter tube. A silicone gel transmits the two types of pressures acting in the body to each sensing portion. The two types of pressures act on each sensing portion in a radial direction of the catheter tube by way of the silicone gel.

An acceleration sensor (1) includes a parallelepiped case (2). A circuit board (3) is secured in the case (2). A sensor chip (5), on which a diffusion strain gauge (5b) is formed, is mounted on the circuit board (3). A cylindrical acceleration selecting element (13) is provided on the case (2). The axis of the acceleration selecting element (13) extends in the x direction. A cylindrical pressure transmitting element (14) is also provided on the case (2). The pressure transmitting element (14) communicates a hollowed part on the top of the sensor chip (5) with the interior of the acceleration selecting element (13). The hollowed part on the top of the sensor chip (5), the pressure transmitting element (14) and the acceleration selecting element (13) are filled with silicon gel (10).

An apparatus for weighing a softened solid rapidly and precisely, wherein no excessive force is exerted on, and no shock is given to, the load cell. The apparatus has a simplified structure including 1/4 cylindrical weighing containers so that the apparatus is easy to disassemble and clean. The inventive apparatus comprises a load cell for transmitting signals; a pair of weighing containers each having a cross-section of approximately 1/4 of a cylinder, arranged closely, and installed on the load cell rotatably around center axis of rotation; a scraping member installed closely to the inner surface of the weighing containers; and a driving unit, which is not connected to said load cell, for opening and closing the weighing containers by reversely rotating them around their axes. This apparatus for weighing a softened solid discharges the weighed substance as it is scraped from the sides of the containers by the scraping member.

A suction-type metering robot hand comprising (a) a hollow suction pad having a gas-permeable obstacle at an opening of the suction pad; and (b) a main body of the robot hand supporting the suction pad and having a vacuum passage communicating with the suction pad. According to the robot hand of the present invention, the provision of the net on the opening of the suction pad makes it possible to suck fragile articles such as a fried cutlet, roasted bean curd, a piece of bread and the like to a desired place.
摘要:
An improved solder-bonding structure is disclosed that is particularly suitable for soldering the components of hybrid ICs. The solder-bonding structure includes a conductor formed on a substrate. The conductor is formed from silver and platinum. A solder layer formed from a tin and silver solder is then formed on the conductor to couple an electronic element to the conductor. In preferred aspects of the invention, the platinum content in the conductor is in the range of approximately 0.7 to 1.0% by weight. The silver content in the solder layer is in the range of approximately 0.1 to 5.0% by weight.
