An apparatus for reducing noise reduction produced by a super sonic jet, comprises a cavity tone generator provided near an exit of a supersonic jet nozzle. The cavity tone generator is a cavity formed in an inner wall of the nozzle exit, and the cavity having a lateral cross-sectional shape similar to a lateral cross-sectional shape of the inner wall of the nozzle exit. More preferably, the cavity and the nozzle exit are formed to have a rectangular lateral cross-sectional shape.

An apparatus for separating a ticket from a ticket sheet containing a plurality of tickets, each of the tickets being separated from an adjacent ticket by a line of perforations. The apparatus includes a cutting part having a feed passage, first and second spaced feed rollers positioned within the cutting part for conducting the ticket sheet along the feed passage, and a cutting roller positioned within the cutting part between the first and second feed rollers for cutting a ticket sheet at the line of perforations. The cutting roller includes an axle and a surface having first and second ends surrounding a length of the axle. The surface of the cutting roller includes a central portion having a first diameter forming a first cutting edge on a circumference thereof, and further includes first and second outer portions. The first outer portion is located between the first end of the surface and the central portion, and the second outer portion is located between the second end of the surface and the central portion. Each of the first and second outer portions has a second diameter which is less than the first diameter and forms a second cutting edge which is smaller than the first cutting edge. A driver is provided for driving the first and second feed rollers at predetermined speeds to bring a line of perforations on the ticket sheet into engagement with the cutting edges of the cutting roller, and a controller is coupled to the driver for controlling the speed at which each of the feed rollers is driven. The feed rollers are driven at different speeds so that parts of the ticket sheet on opposite sides of the line of perforations are pulled in opposite directions while the line of perforations is cut by the cutting edges of the cutting roller thereby separating a ticket from the ticket sheet.

摘要:
In a broadband access network, calls can be kept active even when a telephone network fails. A voice gateway function captures callee telephone number information sent from a caller subscriber telephone to the telephone network and, when the telephone network fails, keeps the call active by retaining the connection between the caller and the callee. Furthermore, when the telephone network fails, the operation mode of the voice gateway and all ONTs is switched from an H.248 gateway mode to an SIP softswitch mode, allowing the voice gateway function to relay communication packets between ONTs and new call connections to be made in the broadband access network.

An organic electroluminescence device includes a pair of electrodes; a hole injection layer and a luminescent layer disposed between the pair of electrodes; and a mixing-preventing layer disposed between the hole injection layer and the luminescent layer and preventing mixing of the material constituting the hole injection layer and the material constituting the luminescent layer.
摘要:
An organic EL device with a voltage applied across an anode and a cathode so that holes are moved in a hole transport layer and electrons are moved in an electron transport layer, and the holes and the electrons are recombined in a light emitting layer to emit light. The light emitting layer is formed of light emitting material having one or more kinds of metallic impurities. By using such a light emitting material, the decrease of light-emission luminance of the organic EL device can be suppressed.

The invention provides an organic electroluminescent device and a method of manufacturing the same which conveniently reduce or suppress the transfer of ionic impurities into a light-emitting layer, and reduce or prevent the light-emitting property in the light-emitting layer from degrading, which promotes life extension. An organic electroluminescent device includes a functional layer having at least a light-emitting layer between a first electrode and a second electrode. At least a part of the functional layer is formed of the inorganic ion exchange material added to the functional material to form the functional layer.

A method of manufacturing an organic electroluminescent device having a functional layer formed by at least a light emitting layer positioned between a pair of electrodes, the method includes the steps of storing a liquid material in a container, the liquid material obtained by dissolving a material for forming the functional layer in a solvent or by dispersing the material for forming the functional layer in a dispersion medium, removing clusters contained in the liquid material, supplying the liquid material to a droplet discharge head, discharging the liquid material from the droplet discharge head, and forming the functional layer by discharging the liquid material onto a substrate.
摘要:
In an organic EL device, when a voltage is applied across an anode and a cathode, holes are moved in a hole transport layer and electrons are moved in an electron transport layer, and the holes and the electrons are recombined in a light emitting layer. In the light emitting layer, excitons are produced by energy released upon the recombination, and the excitons release energy in the form of fluorescence or phosphorescence or emit light when returning to the ground state. The hole transport material is used in the hole transport layer, in which the amount of cationic impurities and/or the amount of anionic impurities are controlled to be small, so that the decrease of light-emission luminance of the organic EL device is suppressed and excellent light emitting properties are maintained for a long period of time.
