A gas sensing device comprises a gas sensing element comprising a gas-sensitive resistive film formed of an aggregate of ultrafine particles of a suitable material deposited on the surface of a substrate of an electrical insulator formed with electrodes. In a method of manufacturing such a gas sensing device, a gas-sensitive material is evaporated in a gas atmosphere to provide the gas-sensitive resistive film of ultrafine particles of the material.
摘要:
A method and apparatus for manufacturing an ultrafine particle film which has great practical utility when deposited on an appropriate substrate. The particle film is produced from various ultrafine particles of, for example, metals, oxides, nitrides and carbides, and is produced uniformly, effectively and efficiently with a high degree of reproducibility. According to a first method, an atmosphere at a gas of a reduced pressure is formed in a vessel, and a forced flow of the gas is formed unidirectionally from an evaporation source to the substrate, so that the evaporated matters from the evaporation source are forced to move together with the forced flow of the gas, so that ultrafine particles which are formed through interaction between the evaporated matters and the gas deposited on the substrate thereby forming the ultrafine particle film. According to a second method, the evaporation source is disposed within a vessel of having a reduced gas pressure as well as a cylinder surrounded by a high-frequency coil. As the coil is energized, the gas in the cylinder is excited. The evaporated matters are forced to flow through the excited gas atmosphere so that ultrafine particles formed by an interaction between the evaporated matters and the excited gas are deposited on the substrate thereby forming the ultrafine particle layer. A third method is a combination of the first and second methods.

摘要:
An electroluminescent display panel formed of phosphor and dielectric layers sandwiched between opposing mutually intersecting arrays of drive electrodes, has the thickness of the phosphor layer set to a value which provides minimum power consumption, for a given level of display brightness. This is achieved by determining a value of capacitance per unit area of the panel which results in a maximum allowable value of time being required to charge each display element, then determining a value of phosphor layer thickness providing minimum power consumption, using the latter value of capacitance and the known value of light emission efficiency of the display.

摘要:
3-(2,4-Dichlorobenzyl)-2-methyl-N-(pentylsulfonyl)-3H-benzimidazole-5-carboxamide, a compound having hypoglycemic activity or PDE5 inhibitory effect, has three forms of crystal forms that are distinguishable by their X-ray powder diffraction values. The most crystallographically stable crystal form is useful as a drug substance for medicines. Another crystal form can be purified efficiently by crystallization, since it forms larger crystals and can be very easily isolated by filtration. Thus this crystal form is useful for purifying 3-(2,4-Dichlorobenzyl)-2-methyl-N-(pentylsulfonyl)-3H-benzimidazole-5-carboxamide.
