摘要： There is provided a method for manufacturing a piezoelectric actuator where the planar shape is adjusted by subjecting the piezoelectric body layer located on one of the outer surfaces in the two or more piezoelectric body layers to a polarization treatment to control remnant polarization of the piezoelectric body layer. The piezoelectric actuator is used as a drive portion of a piezoelectric drive type variable capacitor. The variable capacitor has high mechanical strength and excellent reliability for a long period of time. The relation between the displacement amount of the piezoelectric actuator and the capacity of the capacitor is stable, and the variable capacity is wide.

摘要： There is provided a method for testing a piezoelectric/electrostrictive actuator, wherein the displacement of a piezoelectric/electrostrictive actuator is estimated on the basis of the relations between one or more frequency characteristic values selected from the group consisting of the heights and areas of the peaks of the resonance waveforms and the difference of the maximum and minimum of the first order or first to higher orders of the resonance frequency characteristic values of the piezoelectric/electrostrictive actuator and the k-th order (k=1 to 4) of the first or first to higher orders of resonance frequencies. According to this piezoelectric/electrostrictive actuator testing method, a piezoelectric/electrostrictive actuator can be tested with high precision without actually driving the same as a product and without being accompanied by any disassembly/breakage.

摘要： A seat reclining device includes a pawl having external teeth, a first arm, a second arm, a cam assembly, and a pressing member. The first arm has a pair of guide walls that guide the pawl in the radial direction. The second arm is rotationally supported by the first arm and has internal teeth. When the cam assembly rotates in a forward direction, the cam assembly presses and moves the pawl radially outward to mesh the external teeth with the internal teeth, and presses the pressing member radially outward. When pressed radially outward, the pressing member presses the pawl in the radial direction and a direction from the guide wall towards the pawl. When the cam assembly rotates in a reverse direction, the cam assembly releases the pressing member and moves the pawl radially inward to separate the external teeth from the internal teeth.

摘要： A connector housing with a mat seal, includes a connector housing a mat seal. At an outer surface of a rear wall of the connector housing, a plurality of passages for a silicone gum forming material are provided outside an area where a plurality of terminal insertion holes are formed. On the outer surface of the rear wall and outside the passages, an annular rib is protruded and surrounds an area inside the annular rib. The mat seal is molded by using the area inside the annular rib as a reservoir space in which the silicone gum forming material overflowing from the seal forming cavity is retained, and using at least one of the passages as a passage for a gate through which the silicone gum forming material is injected into the seal forming cavity, and the other of the passages as passages for overflow.
