摘要:
The present invention has an electrode for energization use of a thermal head having an unprecedentedly new electrode construction of a full peripherally surrounding type, so that one heating portion corresponds to one individual electrode without separation or independence of a heating resistor. Thus, the heating efficiency in the printing operation is improved to increase the thermal response property, thus making it possible to save the power. Furthermore, the full periphery surrounding electrode portion is adapted to be completely covered by the heating resistor to remove the dispersion of the resistance values of each dot responsible for the dispersion of the printing width of the heating resistor, and to completely provide uniformity by an energization overload trimming system. The heating efficiency and the thermal response property are improved, and the uneven printing concentration of each dot is removed to make the gradation recording property better, thus making it possible to have an embodiment of a thermal head capable of high-quality printing and having high reliability.

摘要:
Apparatus for controlling humidity comprises a humidity sensing circuit including a humidity sensing element the electrostatic capacitance of which varies in accordance with the ambient relative humidity, and an air-conditioning system responsive to the sensed humidity. The humidity sensing element is charged and discharged repeatedly in accordance with a pulse train signal, and a period required for the voltage across the sensing element is measured during charging by a comparison between the voltage and a reference voltage. The pulse width or the reference voltage may be changed to select a desired reference humidity. A hysteresis characteristic may be given to render the operation of the circuit stable. When an SCR is controlled by the output signal of the humidity sensing circuit, the frequency of the pulse train signal is selected to be greater than four times the frequency of the voltage applied to the SCR.
摘要:
A device comprising a metal substrate serving as a first electrode, a dielectric oxide film formed by oxidation of a surface region of the substrate and a second electrode layer formed porously on the dielectric oxide film. Microscopically, the second electrode layer is only partially in contact with the dielectric oxide film. Accordingly moisture adsorbed through the second electrode layer covers uncoated regions of the dielectric film surface to a variable extent in dependence on humidity, resulting in a change in the electrostatic capacitance across the electrodes. Preferably the device comprises a semiconducting metal oxide layer as an innermost part of the second electrode layer.

A solid electrolyte capacitor superior to a manganese dioxide capacitor and characterized by the use of an oxide of Ru, Rh, Re, Os or Ir either in place of or together with manganese dioxide. The newly utilized metal oxide is good at oxidizing ability and low in resistivity. A solid electrolyte layer comprising the newly utilized metal oxide is formed by pyrolysis of an aqueous solution comprising a soluble salt of the metal on an anodized valve metal. The solution may comprise manganese nitrate too.

摘要:
In a solid electrolyte capacitor, a metallic cathode collector layer is in direct contact with an electrolyte layer which is formed of densely accumulated manganese dioxide particles of 0.1 - 50 .mu.m. The manganese dioxide layer is formed by performing pyrolysis of manganese nitrate in a semi-closed heating chamber of a radiant furnace to offer a resistance to the outflow from the chamber of gaseous decomposition products. The collector layer is formed by spraying, preferably by plasma spraying, of a metal powder typified by copper powder.
