摘要:
Disclosed is an appearance inspection apparatus for inspecting whether an appearance state of a main actuator element is adequate or defective by applying an appearance-inspecting voltage to the main actuator element including an upper electrode formed on an upper surface of a shape-retaining layer and a lower electrode formed on a lower surface of the shape-retaining layer. The appearance inspection apparatus comprises an optical detecting unit for electrically detecting the appearance state of the main actuator element on the basis of light emission caused by the main actuator element, and a judging unit for judging whether the appearance state of the main actuator element is adequate or defective on the basis of a level of a detection signal supplied from the optical detecting unit. Accordingly, it is possible to realize high inspection accuracy, reduce inspection time, and simplify the inspection apparatus. Further, the present invention is also applicable to integrated electronic parts.
摘要:
An apparatus for feeding semiconductor chips has a structural body having grooves which serve respectively as parallel feed paths for semiconductor chips, the feed paths corresponding to respective quality levels of the semiconductor chips, the structural body being made of partially stabilized zirconia. A stopper mechanism for temporarily stopping semiconductor chips fed along the feed paths comprises piezoelectric bodies disposed in the feed paths in front of terminal walls of the feed paths. A counter mechanism for counting semiconductor chips fed along the feed paths have electrodes disposed in the feed paths near the terminal walls. The apparatus serves as a feed system for floating articles with ejected air and feeding the floated articles, and lends itself to being automatized.

摘要:
A mass sensor in which a connection plate and a diaphragm are joined together at their respective sides; a sensing plate is joined to the connection plate at their respective sides in the direction perpendicular to the direction where the diaphragm is joined to the connection plate; a piezoelectric element consisting of a piezoelectric film and an electrode is installed on at least either one of plate surfaces of the sensing plate; and a resonating portion consisting of the diaphragm, the sensing plate, the connection plate, and the piezoelectric element is joined to a sensor substrate. Change in the mass of the diaphragm is measured by measuring change in the resonant frequency of the resonating portion accompanying the change in the mass of the diaphragm.

A mass sensor including: a connecting plate having one or more slit(s) and/or opening portion(s) formed therein and/or having a thin-walled portion and a thick-walled portion formed therein; a diaphragm joined with the connecting plate at respective side surfaces; a piezoelectric element; a sensing plate with the piezoelectric element being provided at least at one part on at least one surface of the sensing plate, which has its side surface joined with a side surface of the connecting plate in the direction perpendicular to the joining direction of the diaphragm and the connecting plate; and a sensor substrate with which at least a part of side surfaces of the connecting plate as well as the sensing plate are joined, and the diaphragm, the connecting plate, the sensing plate, and the piezoelectric element form a resonating portion. The mass sensor can conveniently be used for determining the mass of a substance to be sensed by measuring changes in resonant frequencies caused by changes in the mass of the diaphragm on which a catching substance for catching a substance to be sensed by reacting only with the object of sensing is applied.

There is provided a double-headed mass sensor (25) in which between a first connecting plate (22A) joined to a first diaphragm (21A) at respective sides and a second connecting plate (22B) joined to a second diaphragm (21B) at respective sides, a first sensing plate (41A), on which a main element (44) is provided on at least one plane surface, is bridged, and a resonating portion comprising the diaphragms (21A), (21B), the connecting plates (22A), (22B), the first sensing plate (41A) and the main element (44) is joined to a sensor substrate (27). Change in the mass of each of the diaphragms (21A), (21B) is measured by measuring change in the resonant frequency of the resonating portion accompanying the change in the mass of the diaphragms (21A), (21B). The mass sensor of the present invention enables the easy and highly accurate measurement of a minute mass of a nanogram order including microorganisms such as bacteria and viruses, chemical substances, and the thickness of vapor-deposited films.

A mass sensor includes a diaphragm, a sensing plate having a piezoelectric element arranged on at least a part of at least one surface joining respective sides, a connecting plate sandwiched by the diaphragm and the sensing plate, wherein the diaphragm, the sensing plate, the piezoelectric element, and the connecting plate form a resonating portion. The connecting plate is bridged across the side surfaces of a concave portion formed in a sensor substrate, and the sensing plate is joined to at least the bottom portion of the concave portion. Change in the mass of the diaphragm is measured by measuring change in the resonant frequencies of the resonating portion accompanying the change in the mass of the diaphragm. The mass sensor enables the easy and accurate measurement of a minute mass of a nanogram order including microorganisms such as bacteria and viruses, or chemical substances, or the thickness of vapor-deposited films.

A diaphragm structure includes a ceramic substrate having at least one window portion and a thin diaphragm laminated onto the ceramic substrate so as to cover the window portion, wherein only a part of an interface between the ceramic substrate and the thin diaphragm is joined to form a joint of the diaphragm. A diaphragm structure is free from instability caused by a breakage or deformation of a partition wall between window portions upon punching or laminating even if a diaphragm structure employs a design in which dimensions of a diaphragm portion is maintained and simultaneously a distance between diaphragm portions is made narrow to restrain a surface area excluding a diaphragm portion of a diaphragm structure or a design in which a plurality of diaphragm portion having various configurations and dimensions are disposed.
