摘要:
In a surface acoustic wave device using a Shear Horizontal type surface acoustic wave, at least one interdigital transducer (IDT) is made of a material having a larger mass-load effect than that of aluminum. The metallization ratio of the IDT and the normalization film thickness h/&lgr; of the IDT are controlled such that ripple caused by a transversal mode wave is about 0.5 dB or less, where “h” indicates the film thickness of the electrodes and “&lgr;” indicates the wavelength of a surface acoustic wave.

An apparatus configured to make blanks that would be used to assemble a CVT belt formed from such blanks. The CVT is assembled by arrange a body portion of the blanks on an inner periphery, a head portion on an outer periphery, and a neck portion, which connects the head and body. The apparatus has a die that has an opening shape conforming to a planar shape of the element to be formed. An ejector that has a sectional shape conforming to the opening shape of the blanking blade and is located inside the blanking blade. A punch that has a sectional shape conforming to the opening shape of the blanking blade and moves downward into the blanking blade to blank the element together with the blanking blade, and a pusher that is located around the punch and presses the flat plate-like material against the die.

A solid electrolytic capacitor that includes a laminated body, a solid electrolyte layer, and conductive bases. The laminated body is obtained by laminating a plurality of dielectric-coated valve action metal sheets, each of which includes a valve action metal base and a dielectric coating, and joining together the adjacent valve action metal bases. The valve action metal base has a cathode layer part, and the dielectric coating covers the surface of the valve action metal base at least the cathode layer part. The valve action metal base of at least one of the dielectric-coated valve action metal sheets further has an anode lead part. The solid electrolyte layer is a continuous layer that fills gaps between the dielectric-coated valve action metal sheets and covers the outer surface of the laminated body at the cathode layer parts, and conductive bases are provided in the solid electrolyte layer.

The present invention relates to a technique for moving a mobile component such as a sample and a reagent, in an analyzing article. A method of analyzing a sample according to the present invention includes a first movement step of moving a mobile component from a fluid entrance port (61) to a first goal (511) in a passage (51), and a second movement step of moving the mobile component from the first goal (511) to a second goal (512) in the passage (51), in an analyzing article (Y1). The analyzing article (Y1) further includes a branch passage which branches from the first goal (511), and a first opening for releasing gas from within the branch passage. The first movement step is carried out by establishing communication between inside and outside of the branch passage via the first opening. The second movement step is carried out by providing a second opening downstream from the second goal (512) with respect to a flow direction of the mobile component, thereby establishing communication between inside and outside of the passage.
摘要:
Thin-section slide samples are manufactured from respective embedding blocks containing a biological sample and held in an embedding cassette having imprinted thereon individual data. The embedding cassette is transported to a cutting position where an embedding block is cut into sheet-like thin sections, and the individual data is read out. Each of thin sections is flattened and transferred onto a substrate to form a thin-section slide sample. A memory part stores the individual data read out and a condition table into which is input manufacturing conditions for manufacturing the thin sections. Thereafter, it is evaluated whether or not each of the thin sections is prepared in accordance with the manufacturing conditions input into the condition table.
