Title: Magnetic brush cleaning device
Inventor: OKUNO TATSUO
IPC: G03G21/00
Filed: 1982-08-13
Abstract: PURPOSE:To improve cleaning capacity by disposing two pieces of magnetic brush rolls in a magnetic brush cleaning device of a two component type adjacently to a photoreceptor and supporting carriers having a difference in electric resistivity respectively thereon. CONSTITUTION:The residual toner on a photoreceptor 1 applied with negative electric charge by the 1st precleaning Corotron approaches the 1st magnetic brush roll 34 impressed with a low bias voltage. The toner having high electrostatic charge quantity is attracted by a cleaning carrier having low resistivity onto the roll 34. The toner having low electric charge quantity on the photoreceptor 1 which remains thereon without being removed is applied with negative charge by the 2nd precleaning Corotron 41 and approaches the 2nd magnetic brush roll 35 impressed with a high bias voltage. The toner having low electrostatic charge quantity is attracted by a cleaning carrier having high resistivity onto the roll 35. The cleaning capacity is thus improved.

Title: Ink jet head
Inventor: ISAYAMA TAKUROU
IPC: B41J2/045
Filed: 1979-10-31
Abstract: PURPOSE:To obtain the ink jet head wherein a magnetic ink is used and the jet efficiency is increased, by arranging a magnetic field generating apparatus upstream with respect to a vibrator unit, the magnetic field generating apparatus preventing the magnetic ink from flowing back when the vibrator unit applies pressure to the magnetic ink in a liquid chamber. CONSTITUTION:When a signal P of information such as letters is inputted, driving pulses (a) are outputted from a driving circuit 9, and the driving pulses (a) are applied through a leading wire 5 to the vibrator unit 4 to vibrate it and to generate pressure waves in the ink within the liquid chamber 3, so that ink droplets are jetted from a nozzle 2 and part of the ink is pushed back toward an ink introducing tube 6. At the same time, the driving circuit 9 sends a signal to a time delay circuit 10 of which the signal (b) drives 9 magnetic field driving circuit 11. The magnetic field driving circuit 11 sends a pulse electric current (c) to a coil 13 to drive the magnetic field generating apparatus 8. The magnetic ink within the ink introducing tube 6 is forced to the opposite wall of the tube 6 by magnetic force so that the tendency of the magnetic ink to flow back may be prevented and therefore the  amount of the ink to be jetted from the nozzle 2 can be increased.

Title: Issuing device for stock or the like
Inventor: ARA YUTAKA
IPC: G06Q30/06
Filed: 1987-06-05
Abstract: PURPOSE:To simplify a connection changing job by connecting a stock issuing device main body and a terminal directly or via a public circuit and providing a connection switching means. CONSTITUTION:A stock issuing device main body 1A gives a circuit connection request to a transmission program TP based on a control program CP. A transmission switching means 15 performs the circuit connection processing among a telephone set 31 containing a MODEM, a public circuit 33 and a telephone set 32 containing a MODEM in case of the on-line connection (connection state between a terminal 15c and a line terminal 15a). While the means 15 has a direct progress in case of an in-line connection (connection state between the terminal 15c and an in-line terminal 15b). Then the TP sends a status for the end of circuit connection to the CP to perform transmission and reception of information between the main body 1A and a terminal 34. The CP delivers a circuit disconnection request to the TP when the transmission and reception of information is through and performs the cut processing of the means 15. Then the TP informs the end of the circuit disconnection to the CP. Thus it is possible to cope with both on-line and in-line connections between the main body 1A and terminal equipments 34 and 35. Then it is not required to use two types of transmission programs and therefore a connection changing job is simplified.

Inventor: AOKI MASAMITSU
IPC: C08J5/24
Filed: 1979-11-01
Abstract: PURPOSE: To obtain a low-smelling, translucent, flame-retardant laminated sheet, by impregnating paper substrates containing hydrated alumina with a phenol resin containing a phosphate ester and a polyamide, and laminating the impregnated substrates.  
     CONSTITUTION: Prepregs are prepared by impregnating paper substrates having 3W30% of hydrated alumina dispersed therein at the time of paper making, with a phenol resin composition comprising 30W89% of a phenol resin having a high content of trifunctional components, 10W50% of a phosphate eater and 1W20wt% of a polyamide resin. The prepregs thus produced are molded into laminated sheets. Because the hydrated alumina used as a flame-retarding agent is solid, a problem of storage stability arises when the alumina is applied in the form of slurry in a phenol resin. Accordingly, it is preferable to disperse the alumina into paper substrates. The particle diameter of the alumina is pref., 0.5W70μ. The phosphate ester is added in an amount to provide a phosphorus content of the phenol resin component, of 1W5%, and is pref., a compound represented by the formula, wherein R 1 , R 2  and R 3  are each H or a 1W20C alkyl and 1+m+n=3.

Title: Method for retrieval from routing table
Inventor: UGA MASANORI
IPC: H04L12/28
Filed: 1999-05-21
Abstract: PROBLEM TO BE SOLVED: To decrease the number of bits needed for one entry of the routing table by storing information on the difference between the IP address of a master node and the IP address of a slave node in a Patricia tree in the routing table and retrieving routing information on the destination IP address that an IP packet has. SOLUTION: A deformed tree is constituted, by converting an 8-bit length Patricia tree into 4-bit length difference information. In the routing table corresponding to the deformed tree, the difference 01** between an entry B and an entry A as its parent node is stored as difference information of a table of, for example, the entry B and the number 2 of effective bits of the difference is stored. Furthermore, the difference 11111111 between the entries A and E cannot be represented with four bits, so that a repeating node F is inserted between the entries A and E. Consequently, the deformed tree obtained by converting the Patricia tree and the routing table can be generated to reduce the memory quantity.

Title: Heat treatment for ingaas ion implanted conductive layer
Inventor: OZAWA TOSHIHARU
IPC: H01L21/26
Filed: 1985-06-27
Abstract: PURPOSE:To easily attain in to enhance the activation of a conductive layer as well as to easily attain it to sharpen the carrier concentration distribution thereof by a method wherein an InGaAs ion implanted conductive layer is annealed at temperature in an extent of 630 deg.C to 810 deg.C using a lamp furnace. CONSTITUTION:An annealing is performed on the sample of an InGaAs ion implanted conductive layer, wherein Si<+> ions are implanted at a room temperature, in an atmosphere of nitrogen at temperature in an extent of 560 deg.C to 960 deg.C using a lamp furnace. When the annealing temperature is kept rising from 560 deg.C, the sheet carrier concentration of the layer is made to rise, the carrier concentration value shows 2.56X10<13> at the annealing temperature of 630 deg.C. Even though the annealing temperature is made to further rise, a roughly constant carrier concentration value is shown to the annealing temperature of 810 deg.C. When the activation rates of the layer are figured out from the carrier concentration values obtainable, a high activation rate, such as 85% in the case of the annealing temperature of 630 deg.C and 81% in the case of the annealing temperature of 810 deg.C, can be obtained. The carrier concentration distribution in the depth direction of the sample coincides with the LSS theory very well, an augmentation in the activation rate is contrived, and at the same time, the sharp carrier concentration distribution can be easily obtained.
