摘要:
Disclosed is an organic electroluminescence device which can be stably produced by a wet process and exhibits enhanced external quantum efficiency and reduced coating unevenness and a production method thereof. Specifically, disclosed is a method of producing the organic electroluminescence device comprising at least a layer, which is formed by a wet process comprising of coating a solution of an organic material dissolved in a solvent to form a liquid layer, followed by removal of the solvent by blowing air to form the layer, wherein the relative drying rate of the solvent to butyl acetate is from 1 to 1000, (based on the drying rate of butyl acetate being 100), the thickness of the formed liquid layer is from 1 to 100 μm, a air-blowing rate is from 0.1 to 5 m/s and the time between completion of coating and start of blowing is from 0 to 60 sec.

摘要:
A vibration damping device in which vibration damping performance of a damper having a chamber holding a rolling member is improved. The vibration damping device is adapted to damp vibrations resulting from a pulsation of torque applied to a rotary member by an oscillating motion of a rolling member connected with the rotary member while being allowed to rotate relatively therewith. The vibration damping device is provided with a casing member enclosing the rolling member, and a sealing member that connects the casing member with the rotary member in a manner such that the rotary member is allowed to rotate relatively with the casing member, while preventing oil from entering into an inner space of the casing member where the rolling member is held to oscillate.

An electronic endoscope apparatus is provided and includes: a light source that illuminates a subject with white light; a color imaging device that takes an image of the subject illuminated with white light; and a spectral-image forming circuit that operates RGB three color image signals based on an output from the color imaging device and a matrix data to generate an spectral image signal representative of a spectral image in a color at a designated wavelength. The spectral-image forming circuit is adapted to generate spectral image signals representative of spectral images in respective colors at least three wavelengths different from one another.

A balloon control apparatus includes a balloon, a flow rate adjustment section, a setting section and a control section. The balloon is attached to an insertion section of an endoscope and/or an insertion aid instrument for guiding insertion of the insertion section of the endoscope. The flow rate adjustment section adjusts an air supply flow rate to the balloon and/or an exhaust flow rate from the balloon. The setting section sets the air supply flow rate and/or the exhaust flow rate. The control section controls the flow rate adjustment section so that the air supply flow rate to the balloon and/or the exhaust flow rate from the balloon become the air supply flow rate and/or the exhaust flow rate set by the setting section.
摘要:
A balloon controller for an endoscope apparatus which enables an operator to correctly and immediately grasp circumstances relating to an abnormal condition at the time of occurrence of the abnormal condition. The balloon controller controls expansion and shrinkage of each of a first balloon attached to an insertion portion of an endoscope and a second balloon attached to an insertion assist implement, by supplying air to the balloon or drawing air from the balloon. Pressure indicating portions on which the values of pressures in the first and second balloons are displayed are provided in a front surface of a main body of the balloon controller. When an abnormal condition occurs, an error code and the pressure values are alternately displayed on the pressure indicating portions.
摘要:
A silver halide photographic light-sensitive material is disclosed. The silver halide emulsion layer of the light-sensitive material is sensitized in infrared region of the spectrum by a cationic di- or tri-carbocyanine sensitizing dye and a compound represented by formula I, II, or III; ##STR1## The light-sensitive material is improved in stability of the coating solution of the silver halide emulsion for standing during in its production process and also improved in stability for prolonged storage after production.
摘要:
A microchannel plate has a platelike photosensitive glass substrate and a plurality of microchannels formed separately from each other and extending across the thickness of the substrate. A secondary electron-emission surface is formed on an inner surface of each of the microchannels. Accelerating electrodes formed on two opposite sides of the photosensitive glass substrate, so as to be partially in electrical contact with the secondary-emission surface. The microchannels are formed by applying ultraviolet rays to the substrate through a mask and removing irradiated portions of the substrate by etching.
