摘要:
A fluid delivery device is provided which comprises a microchannel device for cutting out a certain amount of a sample from a micorochannel by controlling a valve opening. The fluid delivery device has a valve for controlling a flow of a fluid, comprising a flow channel for the fluid, and a valve in the flow channel, wherein the valve operates in accordance with a pressure difference between the upstream side and downstream side of the valve caused by the flow of the fluid through the flow channel, allowing the fluid to flow when the pressure difference is lower than a prescribed value P0, and intercepting the fluid not to flow when the pressure difference is P0 or more.

A method for producing a crystalline film by melting and resolidifying a film, characterized in preparing a film having a specific region and obtained either by (A) a step of forming a film in which a “specific region” and an “region continuous to a periphery of the specific region and different in thickness from the specific region” co-exist, or by (B) a step of irradiating a film with an elecrtromagnetic wave or particles having a mass in mutually different conditions between a specific region and a peripheral region thereof, and melting and resolidifying at least a part of the film. As the spatial position of the specific region can be exactly and easily controlled, it is possible to obtain a crystalline film in which a crystal grain is formed in a desired position.

The present invention provides a filling apparatus establishing positional coincidence between creases preformed in a packaging material and actual creases to thereby improve the appearance of a packaging container. A light source irradiates a portion of the outer circumferential surface of a packaging material tube which includes an overlap. A sensor receives light emitted from the light source and reflected from the outer circumferential surface of the tube. The overlap is detected as a peak in the sensor output. Light reflected from an edge portion of the packaging material exhibits greater intensity and is seen as a peak in the sensor output indicating position of the overlap.
摘要:
A projection having a micro-aperture is formed by formiNg a dent having a pointed front end on a substrate, then depositing a light blocking material on the substrate except the front end of the dent, and peeling off the light blocking material from the substrate. The projection is suited as an optical probe of scanning near-field optical microscope (SNOM) for detecting or emitting light through the micro-aperture. For this purpose, the projection is formed on the end of a cantilever or on the end of an optical fiber. The dent having a pointed front end can be formed typically by patterned crystal-axis-anisotropic etching of a silicon substrate and subsequent thermal oxidation of the silicon surface.

摘要:
A nonlinear resistor comprising a sintered body containing zinc oxide as a major component and at least bismuth oxide and boron oxide and electrodes formed thereon, said sintered body having a higher .gamma.-form bismuth oxide phase concentration in upper and/or lower surface layers of the sintered body than in the inner portion of the sintered body, has stabilized properties against long-time voltage application. When the sintered body is further modified by making the .gamma.-form bismuth oxide phase concentration in the periphery portions of the upper and/or lower surface layers lower than that in the inner portions of the upper and/or lower surface layers, the resulting nonlinear resistor shows a higher long-duration current impulse withstand capability.
