Resin material in the liquid state is discharged in mist form toward a heated body by a two-liquid nozzle or resin material in the liquid state is mixed with gas and is discharged in mist form toward a heated body placed under reduced pressure, thereby allowing the resin material to adhere to the heated body and evaporate on the heated body. The evaporated resin material is allowed to adhere to th...

The resistors are formed from refractory metal oxides 101. To provide only one specific resistive characteristic, one stage of hydrogen treatment is performed on a selected part of the refractory metal oxide layer 101 where the resistor is to be formed 101a. Through the hydrogen treatment, the selected part of the refractory metal oxide layer is converted into a semi-conductive oxide or a conducti...

This invention is a blended powder mixture including a thermosetting resin and a solid, non-hydrolyzed, functional low molecular weight organosilane coupling agent. The powder mixture may be used to form a composite coating to protect a steel substrate from corrosion. The composite coating is formed by coating the substrate with an inorganic layer such as a silicate, depositing the powder mixture ...

A method for making a thin film of solid material, including bombarding one face of a substrate of the solid material with at least one of rare gas ions and hydrogen gas ions so as to create a layer of microcavities seperating the substrate into two regions at a depth neighboring the average ion penetration depth, and heating the layer of microcavities to a temperature sufficient to bring about a ...
