Title: Production of polymer
Inventor: TAKIZAWA TOSHIKI
IPC: C08C19/26
Filed: 1992-06-04
Abstract: PURPOSE:To efficiently obtain a polymer having low hysteresis loss by adding a tetrahalogenated tin compound to a polymerization system in polymerizing a conjugated diene and/or a vinyl aromatic hydrocarbon using an organolithium compound as an initiator. CONSTITUTION:A halogenated tin compound of the structural formula SnX4 (X is halogen) (e.g. tin tetrachloride or tin tetrabroride) in an amount of <0.25mol equiv. to >=0.18mol equiv. based on 1mol equiv. polymerization active terminal lithium is added to a polymerization system during a polymer chain growth period just after starting the polymerization to 80%, preferably 25% conversion ratio in polymerizing a conjugated diene (preferably 1,3-butadiene) and/or a vinyl aromatic compound (preferably styrene) in a hydrocarbon solvent using an organolithium compound (preferably n-butyl-lithium or t-butyl-lithium) as an initiator to carry out the polymerizing reaction. After completing the polymerizing reaction, a modifying agent such as a tin compound or an isocyanate group-containing compound, as necessary, is added to produce the objective polymer containing >=50% high-molecular weight polymer having tin-carbon bond chain at a low cost with good productivity.

Title: Extraction column
Inventor: HIRONO SHIYUUICHIROU
IPC: C22B3/20
Filed: 1979-11-07
Abstract: PURPOSE: To prevent the clogging etc. of plates owing to build-up of crystals in a pulsed perforated plate extraction column for solvent extraction, by expanding the pore parts of porous plates to a trumpet shape toward the top and bottom of the plates.  
     CONSTITUTION: In the pulsed perforated plate extraction column, the pore parts of the plates are expanded to a trumpet shape toward the top and bottom surfaces of the plates, and the adjacent expanded parts on the top surface of the plates are mutually contacted. As a result, the flat parts are less provided i the perforated plates and therefore the build-up of solids or crystals is prevented. In addition, the crystals having partly built up during the operation halt are readily desorbable by the pulsation action of the pulser at the resuming of operation.

Title: Bridge cutoff system
Inventor: YAMAGUCHI TAKEHIKO
IPC: H04Q3/68
Filed: 1979-11-08
Abstract: PURPOSE:To make bridge cutoff possible without providing the offering switch independent of the main switch, by providing a folded link for bridge cutoff between the going path switch and the returning path switch of the four-wire space division switch. CONSTITUTION:When the bridge cutoff call to subscriber 31 is generated from the incoming line under the service state between subscriber 31 and the outgoing line, respective corresponding terminals are double-connected in going path switch 33 and returning path switch 34 of the subscriber line concentration part. Therefore, voice from subscriber 31 is flowed to the outgoing line through path (a) and is flowed to the incoming line through path (b). Voice from the outgoing line is flowed to subscriber 31 through channel (g) and is flowed to the incoming line through path (e), folded link 39, and path (c). Voice of the incoming line is flowed to subscriber 31 through path (h) and is flowed to the outgoing line through path (f), folded link 40, and path (d). Thus, bridge cutoff service is possible among subscriber 31, the outgoing line, and the incoming line. As a result, bridge cutoff in the position of the two-wire channel is possible.

Title: Multi-address processing controlling method and its device
Inventor: YAMAMOTO KAZUYA
IPC: G06F13/00
Filed: 1996-05-16
Abstract: PROBLEM TO BE SOLVED: To execute the instruction operation of a multi-address processing by means of a simple operation when document data is transmitted to another processor so as to execute the processing by executing control so as to permit the device of the destination of a group which is indicated by means of a group object to request the processing of processing object data. SOLUTION: A printer group register part 14 registers printers 141-143 for executing multi-address printing as a group. The object expressing the registered group is generated by an object generating part 18. When a client prints the same document in plural print servers 131-133 and the operation is executed to the object of the printer group, the object which is selected by the operation is judged by an input/output interface part 11 and a multi-address print control part 12 executes the multi-address processing. Therefore, an operator does not need to repeat the same operation many times, so that operability is improved.

Title: Production of speaker diaphragm
Inventor: HIROKI TSUTOMU
IPC: H04R31/00
Filed: 1979-11-09
Abstract: PURPOSE:To facilitate mass production, by vapour-deposited Mg alloy or a compound containing B onto the diaphragm surface of the metal or inorganic film and by removing Mg. CONSTITUTION:Since Mg alloy or compound containing B has a low melting point, the nichrome wire and so on can be used as the heating source for the vapour- deposition of Ti foil onto the diaphragm, and the device can be produced cheaply.  For removal of Mg, Mg is scattered by high-temperature and short-time heating  because the vapour pressure of Mg is high, and only B is formed on the diaphragm. Therefore, distortion is not generated in the diaphragm. Since Mg is oxidized faster  than 13, Mg may be removed by dissolution in acid after Mg is oxidized selectively in the oxidizing atmosphere. Thus, the speaker diaphragm where the specific elasticity modulus is high and internal loss is a certain degree can be mass-produced cheaply.

Abstract: PURPOSE:To simplify formation work of a grid feeder and prevent poor connection between the said grid feeder and conductive fine wires by leading out ends of respective conductive fine wires of a grid of a display tube en bloc out of the display tube proper to use it as the grid feeder. CONSTITUTION:Both ends of conductive fine wires 8 composing an anode 7 and the conductive fine wires composing a grid 10 are respectively led out of a  display tube proper 1 en bloc to use these as an anode feeder 8a and as grid  feeder 11a.

Title: Duty controller
Inventor: ZAIZEN KATSUNORI
IPC: H03K3/282
Filed: 1982-08-23
Abstract: PURPOSE:To increase the service life of a load controller and to suppress the flicker, by switching the duty ratio of a duty controller only with the fall timing of a pulse generated from a pulse generator. CONSTITUTION:An AC power supply AC is applied to a pulse generator 2 after the half-wave rectification carried out by a half-wave rectifying circuit 1. A capacitor C2 of the generator 2 repeats charging and discharging with the upper/ lower limit voltage decided by resistances R4, R5 and R7. Thus a pulse VT is generated. A flip-flop IC4 of a switch 6 supplies a waveform obtained by differentiating the pulse VT to a clock input T and therefore fetches the output VD of a signal generator 4 only in the fall of the pulse VT to deliver it to an output Q. As a result, the output VO of a timer 3 is turned on and off in a prescribed working time in spite of the variation of the output of the generator 4. Then a load l is turned on and off by a relay of a load controller 5. Thus the ON/OFF frequencies are reduced to increase the lifetime of the controller 5, and at the same time the flicker is suppressed.

Title: Driving force transmitting device
Inventor: AZUMA HITOSHI
IPC: F16H48/20
Filed: 1986-06-24
Abstract: PURPOSE:To restrain a wheel from idling so as to prevent a driving force from being reduced by providing a worm gear means separately from a driving force transmitting means and by connecting an electric motor, which can be rotated to either the forward or reverse direction, to said gear means. CONSTITUTION:As a wheel 16 is about to start to idle, a control device 90 rotates the output shaft section of an electric motor 66 reversely, and controls revolving speed simultaneously. As a result, the rotation of a spur gear has both a shaft and a worm gear 62 rotated in one direction for having a case 22 rotated via the worm wheel 60 of a differential gear 20. Accordingly, the rotation of a shaft 42 is braked by the rotation of the worm 62 and the worm wheel 60, restraining the wheel 16 from idling. Owing to this constitution, even when one of the wheels is about to idle, power can be positively transmitted to other wheels.
