摘要:
Each of the metal nano-particles present in a dispersion, which comprises at least one metal selected from the group consisting of precious metals and transition metals or an alloy of at least two metals selected from the foregoing metals, comprises a metal particle in which an organic metal compound of a fatty acid and/or an amine-metal complex is adhered to the periphery of the metal particle. This organic metal compound and the amine-metal complex are admixed together in a solvent and then the resulting mixture is subjected to a reducing treatment to thus form a dispersion containing metal nano-particles in a concentration of not less than 5% by mass and not more than 90% by mass. The resulting dispersion is applied onto the surface of a base material, followed by drying the applied layer of the dispersion and then firing the dried layer of the dispersion at a low temperature to thus form a thin metallic wire or a metal film having conductivity.

A movable operating member 5 is swingably borne by the base 1, and its distal end is moved upward by allowing its proximal end 5b to be pressed downward. The movable contact 3 is separated from the stationary contact 2 upward by moving the distal end of the movable operating member 5 upward. The proximal end of the movable operating member 5 is pressed downward by a guide pin 6 in response to a reverse action of a bimetal 7. When a reset shaft 8 is pushed upward, the movable contact 3 is pressed upward, and the guide pin 6 is pressed upward so that the bimetal 7 can be returned to an initial state.

A fine metal particle-dispersion solution and a method for the solution are disclosed which enables to form a transparent conductive film having an uniform distribution of at least two kinds of metals and is produced by mixing an aqueous solution (A) of at lest one metal salt, the metal comprising one or more metals selected from the group consisting of Au, Pt, Ir, Pd, Ag, Rh, Ru, Os, Re and Cu and an aqueous solution (B) including citrate ion and ferrous ion under an atmosphere having substantially no oxygen to produce fine metal particles. A multi-layers conductive film having a low reflectivity, a low resistance and an excellent durability is available by using the dispersion solution of the present invention comprising Ag—Pd fine particles.
摘要:
By using a rivet which serves also as a terminal member, and a sealing member which serves also as an insulating member, the terminal member and the insulating member can be omitted, thereby forming the lid of the secondary battery from only three parts, i.e. the body, rivet and sealing member. The sealing member includes a cylindrical portion and a flange portion which are separate members. The cylindrical portion is formed by cutting a fluororesin tube. The flange portion is formed by punching a polypropylene resin sheet. Thus, the number of parts can be reduced to four, so that it is possible to reduce the parts cost and manufacturing cost as compared to conventional lids.

An ultraviolet range laser comprising a vacuum vessel having an open end portion hermetically sealed with an output mirror glass substrate, which is featured in that the output mirror glass substrate is formed of a glass material which is capable of allowing a laser beam of 337 nm in wavelength to pass therethrough at a transmittance of 80 to 96% as measured when the thickness of the glass substrate is set to 5 mm and whose thermal expansion coefficient falls in the range of 44.times.10.sup.-7 /.degree.C. to 55.times.10.sup.-7 /.degree.C. at a temperature of 0.degree. C. to 300.degree. C., and in that a metallic sealing ring is hermetically attached to the open end portion of vacuum vessel and the hermetical sealing of the open end portion of vacuum vessel with the output mirror glass substrate is achieved by hermetically adhering the output mirror glass substrate onto the metallic sealing ring via a low melting point solder glass interposed therebetween.

A thermostat consecutively comprising a temperature switch unit having a heat sensing element and switching contacts, and a forced reset unit having a plunger and a coil, in which a guide pin is disposed between the heat sensing element and switching contacts, a reset shaft capable of abutting against the switching contacts is provided in the temperature switch unit, and the plunger and reset shaft are moved by energizing the coil, thereby resetting the switching contacts in ON state.
摘要:
A low resistance conductive pigment containing indium oxide crystal grains each including a partial amount of Sn. The amount of Sn ranges from about 1 to about 15 mol % relative to the total amount of Sn and In in each of the indium oxide crystal grains. The conductive pigment further includes a specified surface acidity and a specified volume resistivity. The conductive pigment exhibits improved visibility and averages a primary particle size of up to 0.2 .mu.m,. This allows for the manufacture of superior transparent conductive films which can be useful, inter alia, as a transparent electrode in liquid crystal displays and heating elements having transparent surfaces. In one embodiment, ITO crystals undergo an oxygen extraction treatment, while in another embodiment, surface acidity, is increased by a surface modification treatment. The methods of forming conductive pigments, conductive film forming compositions and conductive resin forming compositions are also disclosed.
