Abstract: PURPOSE: To make the apparatus small in size, light in weight and convenient to carry by providing a condensing-type transmission body array in place of an in- mirror lens type optical system.  
     CONSTITUTION: When a recording sheet 4 is inserted through a paper supply port 5, rolls 6a, 6b are revolved by the sheet detecting means disposed to paper supply rolls 6a, 6b, by which paper supplying is started. When the leading end of the sheet 4 is bited, DC high voltage is applied to the conductive rollers 6a, 6b, by which the sheet is electrically charged with electricity while being supplied simultaneously. When the leading end out the sheet 4 is bited into the conveying rolls 10a, 10b disposed just before a magnetic brush developing device 9, the paper supplying and the rolls are stopped by the sheet leading end detecting means disposed in this part, by which the sheet is placed still on a paper guide 11. After this, the latent image forming part formed with a condensing-type transmission body array 1 and a light source 3 into one body moves in the right direction to perform latent image formation. When this is completed, the sheet is sent to the developing device 9 by the rolls 10a, 10b, where it is applied with the magnetic toner 8 adsorbed on a magnet roll 12 and is thereby developed. After this, it is passed through a pair of rolls 13a, 13b, whereby it is press-stuck with the toners.

Title: Data transfer control system
Inventor: SAKAI NORIO
IPC: G06F15/177
Filed: 1990-04-03
Abstract: PURPOSE:To omit the control of direction of a data bus to be carried out by software and to attain the transmission of data in any direction at an optional time by adding a data bus arbiter to an interface part provided between two controllers. CONSTITUTION:A bus arbiter 3 is provided between two controllers 1 and 2, and one of both controllers can occupy a data bus when the data are transferred between these controllers 1 and 2. For this purpose, two types of control signals are used for bus requests 4 and 6 and bus acknowledges 5 and 7 respectively. That is, the arbiter 3 receives the bus request set by one of both controllers 1 and 2 and arbitrates the bus requests given from both controllers to set a bus acknowledge to the controller that had an earlier bus request. Thus this controller occupies the data bus and performs the transfer of data. As a result, the software is not required to perform the direction control of the data bus and a chosen controller can transfer the data at an optional time.

IPC: C10J3/52
Filed: 1982-05-27
Abstract: In the manufacture of fuel gas or synthesis gas by partially combusting carbonaceous fuel, preferably solid carbonaceous fuel having a high content of non-combustible constituents, finely divided fuel is injected into a shaft-like reactor chamber (10) and is combusted partially while moving down through the reactor chamber, to form a fuel gas or synthesis gas which is removed from the reactor chamber at the upper part (12) thereof, while simultaneously melting non-combustible constituents of the fuel, the resultant melt being taken out of the reactor chamber at the bottom part (13) thereof. A layer (32) of molten material which covers the wall (11) of the reactor chamber and moves downwardly along the wall is sustained by maintaining a selected temperature for substantially instantaneous melting of the non-combustible constituents of the fuel, and by selecting the directions in which the fuel is injected into the reactor chamber so that at least a substantial part of the fuel or the non-combustible constituents contained therein is brought into contact with the wall (11) of the reactor chamber or the layer (32) on said wall during movement down through the shaft. The wall of the reactor chamber is kept cooled in order to maintain thereon, between the wall and the molten layer (32), a frozen coating (33) formed by the non-combustible constituents of the fuel and protecting against slag attack and overheating.

Title: Nonaqueous electrolyte secondary battery
Inventor: WATANABE HIROSHI
IPC: H01M10/052
Filed: 1990-04-03
Abstract: PURPOSE:To improve charge-discharge cycle and reservation characteristics by using as nonaqueous electrolyte one in which a soluble material comprising lithium salt including fluorine is solved in a solvent including at least butylene carbonate. CONSTITUTION:There are used positive electrode 1 mainly composed of manganese dioxide, a negative electrode 2 made of lithium or lithium - aluminium alloy, a material where a substance comprising lithium salt including florine is solved in a solvent including at least butylene carbonate. Since the lithium salt including fluorine is chemically stable in itself, it is hard to react with electrodes 1, 2 under highly active conditions so that the reaction between the solvent and manganese dioxide is restrained, thereby dissolution of the solvent in electrolyte is hard to occur with butylene carbonate being high at its oxide electric potential and a excellent in its oxidation resistance. It is thus possible to improve charge-discharge cycle and reservation characteristics.
