    摘要： Disclosed is a stacked piezoelectric actuator displaceable by bending comprising a plurality of piezoelectric ceramic layers stacked on one surface of a core material, and a plurality of piezoelectric ceramic layers stacked on the other surface thereof, said piezoelectric ceramic layers stacked on both surfaces being successively increased in piezoelectric constant d.sub.31 inner layers to outer layers. The piezoelectric coefficient d.sub.31 is derived from the following equation (2): ##EQU1## wherein k is the electromechanical coupling coefficient, the length vibration of a rectangular plate is taken as k.sub.31, and the unit of the piezoelectric coefficient d.sub.31 is C/N (m/V). The piezoelectric coefficient d.sub.33 in the longitudinal vibration of a column determined by the following equation (3) is a value for the whole stacked layers, and in the present invention, it is necessary that the piezoelectric coefficient d.sub.31 for each of the stacked piezoelectric ceramic layers satisfies the above-mentioned equation. ##EQU2## wherein k is the electromechanical coupling coefficient, and the longitudinal vibration of a column is taken as k.sub.33.

    摘要： A thermostatic expansion valve has a valve shell, e.g., housing, with a high-pressure refrigerant passage and a low-pressure refrigerant passage. The high pressure refrigerant passage has a valve hole and a valve member that changes the valve hole opening rate. A pressure-operating chamber, which has an air-tight chamber and an equalizing chamber separated by a diaphragm, drives the valve member. This pressure-operating chamber, which is attached to the valve shell to detect the temperature, detects the temperature of gaseous phase refrigerant. The valve shell has a hole or opening extending through its outer wall. A plug member seals the hole after a heat-sensitive gas, which senses the temperature of the gas-phase refrigerant passing through the expansion valve, is introduced into the housing through the opening. The plug member is seated on the peripheral edge of the opening and welded to the opening peripheral edge by projection welding. An anti-corrosive material is applied to cover the welded area.

    摘要： A jacquard circular knitting machine provided with a needle cylinder driving mechanism capable of optionally and readily controlling the rotary motion of the needle cylinder according to the pattern to be knitted. A motor interlocked through gears or the like with the needle cylinder rotates according to a needle cylinder rotating procedure stored previously in a magnetic memory medium. Actuators operate according to a pattern forming procedure stored in another magnetic memory medium as a signal is provided by a sensor for detecting the rotary motion of the needle cylinder. Thus a jacquard circular-knitted fabric having predetermined patterns can be knitted efficiently. In addition to the above, a machine is provided with a third magnetic memory medium for storing a yarn feed element switching procedure to carry out a plurality of yarn feed element switching operations at optional timings when necessary while a single course of a fabric is knitted. A yarn feed element switching device is actuated according to the signals given thereto by the third magnetic memory medium as a signal is provided by the sensor for detecting the rotary motion of the needle cylinder. Thus a number of colored yarns exceeding the number of the yarn feed units can be stitched efficiently into a single course of a knitted fabric.
