摘要:
A method and an apparatus of manufacturing an image displaying apparatus having an electron source substrate and a phosphor substrate. The electron source substrate is provided with an electron emitting element formed by covering with a container and by applying a voltage to an electronic conductor on the substrate. While, the phosphor substrate is provided with a phosphor thereon. The substrates are subjected to a getter processing and to a seal bonding process under a vacuum condition through a processing chamber, to complete an image forming apparatus. An improvement resides in miniaturizing and simplifying operation, and in greater manufacture speed and mass production.

摘要:
An electron source comprises one or more electron-emitting devices, especially of surface conduction type, and is provided with means for supplying an activating substance to the device(s). The means comprises preferably a substance source and a heater or electron beam generator for gasifying the substance source. The electron source can be combined with an image-forming member (e.g. fluorescent body) to constitute an image-forming apparatus. The means is used for in situ activation or re-activation of the electron-emitting device(s).

An electron-emitting device having an electroconductive film including an electron-emitting region and arranged between a pair of electrodes is manufactured by forming an electroconductive film on a substrate and producing an electron-emitting region in the electroconductive film. The electroconductive film is formed on the substrate by heating the substrate in an atmosphere containing a gasified organic metal compound to a temperature higher than the decomposition of the gasified organic metal compound.

This invention provides an apparatus for measuring ozone in which interference effects of SO.sub.2 are intended to be reduced. This invention comprises a reference gas line for generating reference gas with ozone removed by allowing the sample gas to pass through the ozone decomposer with silver wool used as a catalyst, a sample gas line for introducing the sample gas as it is, an ozone analyzer to which the reference gas line and the sample gas line are connected via a selector valve and which measures the ozone component in the sample gas by introducing the reference gas and the sample gas alternately at specified intervals, and a temperature controller installed to the ozone decomposer for setting the catalyst reaction temperature to a range from 100 to 130.degree. C.

The liquid crystal device is constituted by disposing a display layer between a pair of electrode plates. The display layer comprises a stretched porous polymer film having open pores and a low-molecular weight mesomorphic compound impregnating the polymer film. The display layer further comprises a porous polymer film having a three dimensional network structure characterized by a fibril diameter of at most 0.3 micron, and a low-molecular weight mesomorphic compound impregnating the polymer film. The display layer still further comprises a first display layer comprising a porous film and a low-molecular weight mesomorphic compound impregnating the porous film, and a second display layer comprising the low-molecular weight mesomorphic compound.
摘要:
A memory medium includes a memory layer of a polymer liquid crystal and a reflection layer disposed on a substrate. A record part having a different refractive index from that of a non-record part is formed in the memory layer so that the record part and the non-record part have a difference in optical thickness of the memory layer. In a reproduction step, the memory medium is irradiated with a reproduction beam of coherent light so that the reproduction beam is transmitted through the memory layer, reflected at the reflection layer and re-transmitted through the memory layer, during which the reproduction beam is subjected to interferential diffraction due to the optical thickness difference between the record part and the non-record part to allow readout of the recorded data.
