Abstract:
Disclosed herein is a fine and thick wiring drawn at high speed in such a manner that a region on the substrate, on which region the liquid droplet is scheduled to impact, is heated beforehand, and that immediately after the impact of the liquid droplet on the substrate, the liquid droplet is promptly solidified so as thereby to suppress the spread of the liquid droplet due to the wettability of the liquid droplet to the substrate, and also to suppress the clogging of the nozzle due to the heating of the substrate. Thereby, even in the case where a liquid droplet having a larger volume than before is used, high-speed drawing of a thick and fine wiring having a line width approximately equal to the liquid droplet size is realized independently of the substrate material.

Abstract:
The present invention provides a simple method using aerosol deposition, for manufacturing a piezoelectric film that will simultaneously satisfy various characteristics required of a piezoelectric film. In the method, the piezoelectric film is formed on a substrate by ejecting an aerosol containing particles of a piezoelectric material onto the substrate so that the particles adhere thereto, and a second piezoelectric layer is formed on the first piezoelectric layer by conducting the ejection such that energy used for crushing the particles when the particles collide with the substrate is less than in the formation of the first piezoelectric film.
Abstract:
A method for forming an ultrafine particle brittle material at low temperature which includes the steps of applying a mechanical impact force or a pressure to a ultrafine particle brittle material so as to have a percentage in the ultrafine particles having a primary particle diameter less than 50 nm in all the particles of 10 to 90%, subjecting the resulting brittle material to a heat treatment at a temperature not higher than the sintering temperature thereof so as to have the above percentage of 50% or less, and then applying a mechanical impact force not less than the crushing strength to the resultant material, to crush the material, thereby joining the ultrafine particles in the brittle material with one another, to form a formed article of the ultrafine particle brittle material; and an ultrafine particle brittle material for use in the method.
Abstract:
An apparatus for manufacturing a composite structure body is provided which forms structure body having the constitution in which the crystals of more than one type of brittle material are dispersed and having novel properties without involving a heating/sintering process. The apparatus includes an aerosol generator configured to generate an aerosol. The aerosol is generated through dispersing fine particles of more than one type of brittle material, or dispersing composite fine particles, in a gas. The apparatus also includes a nozzle configured to spray the aerosol, a classifier configured to classify the brittle material fine particles in the aerosol, and a disintegrating machine for disintegrating agglomerations of the brittle material fine particles in the aerosol. The composite structure body is manufactured in reduced pressure conditions by bombarding a substrate with the aerosol at a high velocity, whereby at least one of crystals and microstructures of said brittle materials are dispersed.

Abstract:
A masking layer is formed on the light-emitting mirror surface of a semiconductor laser body. The masking layer is capable of blocking light emitted from the semiconductor laser body and of being thermally melted and evaporated by exposure to the emitted light. When the masking layer is formed on the light-emitting mirror surface of the semiconductor laser body, a small light-emitting hole is defined in the masking layer by the heat of the emitted light which is effective to prevent the material of the masking layer from being evaporated on a portion of the light-emitting surface.
