Title: Burner unit and method for operating burner
Inventor: TADA HIROTO
IPC: F23N1/00
Filed: 1996-02-07
Abstract: PROBLEM TO BE SOLVED: To alleviate the operation of regulating the supply of fuel to match a load change while maintaining the burning efficiency of a boiler high by disposing a plurality of injection holes at the front surface of a burner at specific positions, and splitting or three-branching the fuel passages of the holes in the burner to arrive at the rear surface of the burner. SOLUTION: When a burner is, for example, operated at a low load to match the load change of a boiler, fuel is introduced to the first passage 4 of a burner 1 via a fuel main valve 12 and a first fuel valve 7, and injected together with atomized vapor from an injection hole into a furnace. In the case of operating at a high load, a second fuel valve 8 of high load is opened, the fuel is introduced to a second passage 5, combined with the fuel from the passage 4, and injected into the furnace. In the case of switching from the high load to the low load, the valve 8 is closed, to purge the fuel in the passage 5, a second purging valve 9 is slowly opened, and closed after a predetermined time. Thus, the burning efficiency is not lowered for the large or small load change, and the operating efficiency is raised.

Title: Semiconductor device and its manufacture
Inventor: YAMAGUCHI NOBUHIRO
IPC: H01L23/52
Filed: 1997-02-04
Abstract: PROBLEM TO BE SOLVED: To secure the reliability of wiring by improving the electromigration resistance of the wiring by coating most of the outer peripheral surface of the wiring with a conductive film having a high melting point. SOLUTION: After a Ti film 3, a TiN film 4, an Al-Si film 5, and a TiN film 6 having prescribed shapes are successively formed on an interlayer insulating film 2 composed of, for example, an SiO2 film formed on an Si substrate 1, a TiN/W film 7 is formed on the side walls of the films and wiring is formed in such a structure that the entire outer peripheral surface of the Al-Si film 5 is coated with the Ti film 3, TiN film 4, Al-Si film 5, TiN film 6, and TiN/W film 7. Therefore, even when an excessively large current larger an allowable current flows, to the wiring, the movement of grain boundaries in the Al-Si film 5 caused by an electron flow can be prevented. Even when the Al-Si film 5 is disconnected, in addition, a by-pass route can be secured for the current, because not only the Ti film 3, TiN film 4, and TiN film 6 but also the TiN/W film 7 have current by-passing functions.

Filed: 1988-01-31
Abstract: PURPOSE:To attain interfacing with a packet handler supporting the standard X25 packet procedure by taking linkage of a layer 2-multiple link with the X25 packet link in a form of multiplexing/demultiplexing so as to constitute a D channel packet interface. CONSTITUTION:In the case of packet transfer from an ISDN(Integrated Service Digital Network) exchange system 1 toward a packet handler system 14, interwork information including LAPD(Link Access Procedure on the D-channel) layer 2 multiple information is sent from the ISDN exchange system 1 to the link controller 10 through an ISDN exchange system interwork line 9. Then the link controller 10 sends a control signal to take linkage between the D- channel packet link and the X25 packet link base on the LAPD layer 2 multiple information through the control line 11 to an LAPD/LAPB conversion processing unit 5. The D-channel packet sent from the ISDN exchange system 1 is sent to the packet handler 14 as the X25 packet by the linkage. Thus, the direct interfacing with the packet handler supporting the standard X25 packet procedure (layers 2 and 3) is attained.

Abstract: PURPOSE:To make ionic current distribution uniform and to extend operation voltage range by partially arranging electric insulating parts on a discharge electrode so as to disperse corona discharge start points (parts on which an electric field concentrates) on the electrode. CONSTITUTION:Electric insulating parts 2 of an insulator (putty) are partially arranged on a discharge electrode 1 so as to disperse and distribute corona discharge start points (parts on which an electric field concentrates) on the electrode 1.

Title: Analysis of organic acid
Inventor: WADA AKIO
IPC: G01N30/88
Filed: 1983-02-12
Abstract: PURPOSE:To enable the quantitative analysis of an org. acid excellent in linearity and reproducibility by high performance liquid chromatography, by adding a pH indicator and a buffer solution in a reaction liquid. CONSTITUTION:An acidic substance represented by an org. acid is separated and eluted in a separation column 6 by an elution liquid due to an acid such as HClO4. In this case, a reaction liquid 2 comprising a pH indicator such as bromothymol blue in which Na2HPO4 is contained is added to the eluted solution and reacted with the acidic substance therein under mixing in a reaction coil 7. As a result, the pH of the solution is changed corresponding to the amount of the specimen component and a part of bromothymol blue in the reaction liquid 2 is changed to an acidic state with the pH change. In this case, the absorption spectrum of bromothymol blue is remarkably different corresponding to an acidic state and a basic state and, by performing monitoring by the wavelength in the vicinity of the absorption peak of the acidic state, the content of the acidic substance can be detected selectively in excellent linearity.

Filed: 1978-02-28
Abstract: PURPOSE: To obtain good images using one component type developer without any useless consumption of toner, by applying different specified bias voltages to a developer feeder in developing and in not developing.  
     CONSTITUTION: Photosensitive drum 14 is positively charged with corona charger 15, and a negative latent image is formed by imagewise exposure. Toner having a volume resistivity of above 10 13  ohm.cm in a powder state is fed from hopper 18 to conductive developing roller 17, and the toner is positively charged with toner charger 20 made of friction charging blades. In developing, positive voltage is applied to roller 17 from voltage supply E 1  of bias voltage controller 19, and the toner is attached to apparently negative low voltage areas, resulting in effecting reversal development. When development is stopped, negative voltage is applied to roller 17 from voltage supply E 2 , thereby permitting the toner not to be attached to drum 14, because toner charge polarity is positive, even if residual voltage on drum 14 is as high as several ten volts.
