摘要:
A polyimide thin film is formed on a substrate by imparting energy under vacuum, by means of heating, ultraviolet light or electron beam irradiation, or a combination thereof, to a polyimide having in the polymer main chain imide bonds and decomposable bonds such as carbon-carbon single bond differing from the imide bonds so as to break the decomposable bonds.

摘要:
A process for purifying propylene oxide characterized by Subjecting a liquid reaction mixture containing propylene oxide, and water, hydrocarbons and oxygen-containing organic compounds as impurities obtained by reacting cumene hydroperoxide with propylene to extractive distillation using an extractant of a hydrocarbon having 7 to 20 carbon atoms with an extractive distillation column, and controlling a concentration of propylene glycol in the extractant supplied to the extractive distillation column to 20% by weight or less.
摘要:
The present invention provides a cathode ray tube which exhibits a favorable contrast by enhancing a speed modulation effect. A front-stage anode electrode and a focus electrode which constitute an electron gun are respectively divided into a plurality of portions. A plurality of portions of the divided front-stage anode electrode are arranged in the tube axis direction at given intervals and are electrically connected with each other. A plurality of portions of the divided focus electrode are arranged in the tube axis direction at given intervals and are electrically connected with each other. Due to gaps formed in the front-stage anode electrode and the focus electrode, the speed modulation effect is increased.
摘要:
A humidity control apparatus for realizing the dehumidification, humidification, and ventilation operations in a compact configuration. The apparatus includes a rotary humidity control element, an electric heater, and sucking and/or forcing blowers. The rotary humidity control element is of metal silicate gel polymerized in honeycomb laminates of ceramics, and is sectioned into a drying function part, a heat recovery function part, and a humidification function part, for use. The drying function part absorbs and removes moisture from air passing therethrough at room temperatures. The heat recovery function part recovers heat of air passing therethrough. The humidification function part moistens the air passing therethrough if the air is high in temperature. The electric heater is provided on an air passageway between the heat recovery function part and the humidification function part, for heating the air to be introduced to the humidification function part. The first suction- or forcing blower is provided on a first air passageway, and the second suction- or forcing blower is provided on a second air passageway. By the action of the blowers, an outdoor and interior airs are fetched from the exterior and the interior respectively, passed through the rotary humidity control element, and discharged. The air passageways are changed so that the apparatus is operated for dehumidification, humidification, or ventilation selectively.
摘要:
A light control element comprising a light control layer containing an electron donating organic compound and an electron accepting organic compound and means for applying an external electric field having an intensity less than a value which is required to cause phase transition in the light control layer to the layer, wherein charge transfer excitons are produced in application of the external electric field.
摘要:
In an injection molding machine, a skin layer resin 26 is injected from a first hot runner 10b into a cavity C in a mold or molds and then a resin passage between the first hot runner 10b and the cavity C is closed, thereby finishing the injection of the skin layer resin 26. A core layer resin 28 is injected from a second hot runner 12b into the cavity C in the mold(s) at a predetermined timing during the period between the start and end of injection of the skin layer resin 26, thereby molding a sandwich molded product without hesitation marks.
