摘要： A valve includes a valve body, a diaphragm dividing the inside of the valve body into first and second valve chambers and being displaced under a pressure of fluid, first and second openings in communication with the first valve chamber, and a third opening in communication with the second valve chamber. When a pump is not driven, the force applied to a side of the diaphragm facing the second valve chamber is greater than the force applied to a side of the diaphragm facing the first valve chamber, and the second opening is sealed by the diaphragm. When the pump is driven and the force applied to the side of the diaphragm facing the first valve chamber becomes greater than the force applied to the side of the diaphragm facing the second valve chamber, the diaphragm allows the first and second openings and to communicate with each other.

A plurality of substantially circular concentric segment electrodes are provided on the piezoelectric element, and are provided with voltages with phases that are shifted. A wavy ring deformation is thus produced on the piezoelectric element. A pocket produced between the piezoelectric element and the substrate is moved in a radial direction so as to convey a fluid from an outer substantially circular portion to a central portion and to discharge the fluid from the central portion.

摘要： A piezoelectric fan device includes four piezoelectric fans that are arranged side-by-side in their width direction, and ends of the piezoelectric fans opposite to other ends in which the blades extend are coupled side-by-side and supported by a support. The piezoelectric fans include piezoelectric vibrators arranged to flexurally vibrate when a voltage is applied thereto and blades coupled to the piezoelectric vibrators such that the blades can be excited by the piezoelectric vibrators. Two central piezoelectric fans are driven in the same phase and the other two piezoelectric fans are driven in the opposite phase by a voltage applying device. Accordingly, not only vibrations of the centroid acting on the support but also moments about three axes are cancelled out.

摘要： A piezoelectric pump includes a piezoelectric element, an intermediate plate, and a vibrating plate. The piezoelectric element has a substantially flat plate shape. The intermediate plate is bonded to a principal surface of the piezoelectric element and applies a residual stress in a compressive direction to the piezoelectric element. The vibrating plate is bonded to the intermediate plate such that the vibrating plate faces a principal surface of the piezoelectric element and receives a residual stress in a compressive direction from the intermediate plate. In addition, the vibrating plate defines a portion of a wall surface of a pump chamber having an open hole. A fluid passage is provided in the piezoelectric pump. The fluid passage communicates with the outside of the chamber at one end thereof, and communicates with the pump chamber through the open hole at the other end.

摘要： A blower body is provided with a first wall and a second wall, and openings are provided in the walls at positions facing the approximate center of a diaphragm. An inflow passage that allows the openings to communicate with the outside is arranged between the two walls. When the diaphragm is vibrated in response to a voltage applied to a piezoelectric element, the first wall vibrates near the opening and sucks in air from the inflow passage so that the air can be ejected from the opening. A plurality of branch passages which provide sound absorption are connected to an intermediate section of the inflow passage so as to prevent noise generated near the opening from leaking from an inlet.

摘要： A piezoelectric micro-blower capable of efficiently conveying compressive fluid without use of a check valve and ensuring a sufficient flow rate. The micro-blower has a blower body with a first wall and a second wall. Openings are formed in the respective walls and face a center of a diaphragm. An inflow path allowing the openings to communicate with the outside is formed between the walls. By applying a voltage to a piezoelectric element to cause the diaphragm to vibrate, a part of the first wall close to the first opening vibrates. Thus, gas can be drawn from the inflow path and discharged from the opening in the second wall.

摘要： A piezoelectric pump capable of generating a large displacement at a central portion of a piezoelectric element even when a driving voltage is relatively low and preventing short-circuits caused by migration. The piezoelectric pump includes a pump body with a pump chamber, and a piezoelectric element that closes the pump chamber. The central area and the peripheral area of the piezoelectric element are bent in opposite directions by applying voltages to the piezoelectric element so that the volume of the pump chamber is changed. The piezoelectric element is a laminate including a plurality of piezoelectric layers with electrodes interposed therebetween. The central area and the peripheral area of each piezoelectric layer are polarized opposite to each other in the thickness direction, and the electrodes are formed such that voltages in the same direction in the thickness direction are applied to the central area and the peripheral area of each piezoelectric layer. Since voltages at the same potential are applied to the electrodes formed in the same planes of the piezoelectric layers, short-circuits caused by migration can be prevented.

摘要： A signal conductor whose first end is an open end, and a ground conductor are connected to associated measurement ports of a network analyzer. A short standard is connected between the signal conductor and the ground conductor at least three points in the longitudinal direction of the signal conductor, and electrical characteristics are measured, thereby calculating error factors of a measurement system including a transmission line. An electronic device to be measured is connected between the signal conductor and the ground conductor, and an electrical characteristic is measured. The error factors of the measurement system are removed from the measured value of the electronic device to be measured, thereby obtaining a true value of the electrical characteristic of the electronic device. Accordingly, a highly accurate high-frequency electrical characteristic measuring method, using a reflection method, that is not affected by connection variations can be implemented.

The relative correction adapter has a characteristic that modifies the electrical characteristics generated by the production test fixture 5B having an electronic component under test mounted thereon into electrical characteristics generated by a standard test fixture 5A having the electronic component under test mounted thereon. An error factor of the relative correction adapter 31 is identified from a standard test fixture measurement value and a production test fixture measurement value of a correction data acquisition specimen 11B. A production test fixture measurement value of the electronic component under test 11A is corrected with the error factor of the relative correction adapter 31 to thereby obtain the standard test fixture measurement value of the electronic component under test 11A which is assumed to be obtained when the electronic component under test 11A.
