摘要:
Deposited on a glass or ceramic substrate for a thin-film microcircuit board such as a hybrid IC board or a transparent electrode is a thin-film laminate, which comprises a dispersion metal thin-film dispersible and evaporable upon application of an energy above a threshold value and an electrical property-imparting film defining a conductor or a resistor. Then a high intensity of light having an energy sufficient to cause dispersion is applied selectively on the thin-film laminate, thereby removing exposed portions of the thin-film laminate as a result of dispersion and evaporation thereof. Unexposed portions of the thin-film laminate provide a desired pattern. The electrical property-imparting film is a thin-film of noble metal such as gold, silver or platinum or a thin film of transparent electrode material such as SnO.sub.2 or In.sub.2 O.sub.3, which is not easily dispersible upon application of the above energy.

摘要:
A novel printed circuit board with a circuit of high precision having a polymer coat layer between a base and a dispersion imaging material layer and a pattern circuit on undispersed portions of the dispersion imaging material layer. Such a printed circuit board is prepared by a simplified process which comprises essentially two steps, namely, exposure of the dispersion imaging material through a circuit pattern mask to obtain a pattern circuit of the unexposed portions and conductive metal plating wherein said unexposed portions are selectively deposited with the conductive metal due to the specific effect of provision of the polymer coat layer directly under the dispersion imaging material layer.

摘要:
Vesicles are suspended in a lipophilic ion solution and the lipophilic ion concentration is changed by the permeation of the lipophilic ions into the vesicles. An electrode selectively responsive to the lipophilic ions is immersed in the suspension to detect the time-change rate of the electrode potential, thereby to obtain a change in the lipophilic ion concentration with respect to time, from which are measured membrane characteristics of the vesicles, such as the permeability of a vesicular membrane to the lipophilic ions.

摘要:
A dry image forming material comprising (a) a non-photosensitive organic silver salt oxidizing agent, (b) a reducing agent for a silver ion and (c) a halogen molecule, which material is excellent in that a high sensitivity can be obtained and the occurrence of fog is extremely small. The sensitivity can be further improved by incorporation of a halogen ion source in addition to the halogen molecule. Furthermore, the dry image forming material can be improved, with respect to light stability of the raw image forming material and stabilities to heat and humidity, by incorporation of a nickel compound and/or a cobalt compound. In the dry image forming material of this invention, further incorporation of a carboxylic acid anhydride exerts a remarkable anti-fogging effect. The dry image forming material of this invention is non-photosensitive under normal lighting conditions and therefore, can be prepared, handled and stored in a light room. An image can be easily, simply formed only by preliminary heating, light exposure and heat development of the image forming material.

A hydraulic fluid tank includes a tank main member of a box-shaped member with a return port and a drawing port that are opened therein; and a divider member that is located in an interior of the tank main member and defines a path of fluid flow from the return port to the drawing port. In addition, the divider member is formed so that the fluid flow makes at least one turn in a vertical direction and at least one turn in a width direction.
摘要:
A method of bonding a piezoelectric element and an electrode, including the steps of forming a first coating of a material selected from the group consisting of Au, Al, Zn, Cu, and Sn on a bonding surface of the piezoelectric element, and forming a second coating of a material selected from the group consisting of Au, Al, Zn, Cu, and Sn on a bonding surface of the electrode. The combination of the materials of the first and second coatings is preferably Au/Au, Au/Al, Zn/Cu, or Sn/Cu. The method further includes the step of bringing the first and second coatings into close contact with each other and heating them under pressure to form a metallic bond or intermetallic compound between the first and second coatings, thereby bonding the piezoelectric element and the electrode.
