摘要:
This invention provides a stacked ceramic body that prevents reaction between components of dielectric layers and components of electrode layers of an unsintered stacked body during sintering and in which both components do not easily form a liquid phase, and a production method of such a stacked ceramic body. A print portion 13 is formed on a green sheet 1, 12 containing lead by use of an electrode paste consisting of copper oxide as its main component. A desired number of print sheets 10 are stacked to give an unsintered stacked body 15. Degreasing is conducted in an atmosphere to degrease organic components. The print portion 13 is subjected to reducing treatment in a reducing atmosphere containing hydrogen and is converted to a print portion 13 containing copper as its main component. The unsintered stacked body 15 is sintered in a reducing atmosphere. Dielectric layers containing lead and electrode layers for applying a voltage to the dielectric layers are alternately stacked, and an oxidation portion containing copper is formed in the proximity of a surface of the electrode layer. A thickness of the oxidation portion in a stacking direction is 0.5 to 2 μm and a copper content in the oxidation portion is 1 to 30 wt %.

This invention provides a method for producing a stacked ceramic body that does not require strict control of an oxygen partial pressure in a sintering gas. To produce a stacked ceramic body by alternately stacking dielectric layer and electrode layers, an unsintered stacked body 2 is prepared by alternately stacking unsintered dielectric layers containing a PZT type dielectric material and unsintered electrode layers containing an electrode material, and is sintered in a sintering gas to which a dielectric layer anti-reducing agent 21 and an electrode layer anti-oxidant 22 are introduced. Alternatively, sintering is conducted in a gas containing only the dielectric layer anti-reducing agent 21 or in a gas containing only the electrode layer anti-oxidant 22.

A spontaneous light emitting display device with low power consumption suppresses fluctuation in characteristics of driving elements of light emitting pixels and has no fluctuation in light emitting luminance of a light emitting element. For each of light emitting pixels arranged in a matrix, a respective photoelectric converting portion detects light emitted from the corresponding light emitting pixels is provided, so that a current flowing to the light emitting pixels is controlled by using a voltage produced from the respective photoelectric converting portion. The device suppresses luminance variation of the light emitting pixel even when the conversion gain of the photoelectric portion varies.
摘要:
A flow sensor detects a flow rate of cooling air from a compressor, and a determination is made as to whether or not the detected flow rate is abnormal. A determination is made by a diaphragm position sensor as to whether or not a diaphragm is located at such a critical position that a quantity of light illuminated onto a photographic film is large, possibly resulting in degeneration of a photographic film. A lamp is turned off if the diaphragm is located at the critical position and the flow rate of the cooling air is abnormal.
