Abstract: PURPOSE:To efficiently obtain a polymer which has a high cis content and a narrow mol.wt. distribution and shows excellent rubber properties by polymerizing a conjugated diene in the presence of a composite catalyst comprising specific components including a rare earth metal carboxylate. CONSTITUTION:A composite catalyst is prepared from a rare earth metal carboxylate represented by the formula (wherein Ln is a rare earth metal, R<1> to R<3> each is a 1-10C alkyl, R<4> is H or a 1-10C alkyl, and n is 1, 2, or 3) (e.g. neodymium 2,2,3,4-tetramethylpentanoate), an organoaluminum compound (e.g. trimethylaluminum), and a halogenated Lewis acid (e.g. diethylaluminum chloride). In the presence of this catalyst, a conjugated diene (e.g. butadiene) is bulk-polymerized or is solution-polymerized in a hydrocarbon solvent into a conjugated diene polymer.

IPC: G03G15/047
Filed: 1993-11-30
Abstract: PURPOSE:To prevent a variation in image formation even right after the start of an operation and to form a uniform image even when residual potential after destaticization is high. CONSTITUTION:In the pre-electrification/destaticization of an image forming device 11, destaticization in a pre-electrifying/destaticizing process is performed by a contact destaticization system at least one time.

Title: Proportional solenoid valve for flow control
Inventor: AKAMINE KOUSHIN
IPC: F16K31/06
Filed: 1992-11-11
Abstract: PURPOSE:To attain smooth flow control and reduce the dispersion of the flow caused by the dispersion of the input current by eliminating a quick flow change, and making the inclination gentle in each state of the flow characteristic of a proportional solenoid valve. CONSTITUTION:In a flow control proportional solenoid valve constituted of a solenoid 19, a body 11, and a spool valve 17, controllers 20, 21 of the input port 13 of the body 11 are formed into a taper shape, and the controller area change rate against the slide quantity of the spool valve 17 is reduced. Since the controller area change rate against the slide of the spool valve 17 is small, the control flow is not changed quickly, the inclination of the flow characteristic can be made gentle, the flow control against the input current is made smooth, and the characteristic with little dispersion can be attained.

Title: Servo magnetic disk device
Inventor: SAKURAI TETSUJI
IPC: G11B21/10
Filed: 1988-11-30
Abstract: PURPOSE:To improve track following-up ability by reading servo information on a medium, storing the dislocation quantity each information to a RAM for each servo information, reading position dislocation quantity between the servo information from RAM by a CPU and sending a corrected position control signal to an actuator control part. CONSTITUTION:At the time of device rising, a servo signal on a medium 5 is read without loading servo on a specified track and the position dislocation quantity is judged by a CPU 1. Position dislocation quantity 16 is related with a position on the track and stored to a RAM3 for each servo signal or with being thinned out. At the time of normal operation, the position dislocation quantity between the servo signals is read from the RAM 3 and the correction is loaded to the signal which is sent to an actuator control part 2. Thus, since read position dislocation quantity 17 is also adjusted in addition to the adjustment of the position dislocation quantity 16, a magnetic head is moved to a next servo signal position and the track following-up ability can be improved.

Title: Connection setting and restoring system in atm network
Inventor: MASUO HITOSHI
IPC: H04L45/28
Filed: 1996-10-25
Abstract: PROBLEM TO BE SOLVED: To quickly set connection and to avoid the degradation of the quality of the connection by holding the information and immediately reflecting it on route calculation, when crank-back is performed once at the time of setting up the connection. SOLUTION: When a connection set-up request is generated from a terminal 7, a node 1 obtains the nodes 1→2→4→6→a terminal 8 of the route information of a route candidate table. Then, the node 1 judges whether or not the route satisfies the requested quality by obtaining the information of a network topology table and establishes the connection when it is satisfied. In this case, at the time of receiving a crank-back message that the requested quality is not satisfied between the nodes 4 and 6, the node 1 sets the information to the network topology table, calculates a route and updates a route candidate table. Thus, the route of the nodes 1→3→5→6 is quickly set and restored, and the degradation in line quality is prevented as well.

Title: Diaphragm for speaker
Inventor: OTA SHUHEI
IPC: H04R7/02
Filed: 1987-12-01
Abstract: PURPOSE:To make the weight of a speaker light and to prevent the resonance sound of the material by reinforcing the resin by means of the cloth employing high strength and high elastic modulus fibers having a specific tensile strength and tensile elastic modulus. CONSTITUTION:The diaphragm is made of a resin 3 and a cloth made of high strength and high elastic modulus polyethylene fibers 2a, 2b whose tensile strength is 20g/d or over and tensile elastic modulus is 500g/d or over (1g/d=9.0 kg/mm<2>). The cloth in use may be any of non-woven fabric, knitting and textile but it is preferable to employ the textile from the standpoint of the balance of the specific elastic modulus and the internal loss of the diaphragm obtained. The diaphragm 1 is excellent also in small specific gravity and larger internal loss in comparison with a conventional diaphragm made of a inorganic fiber reinforced plastic as well as in specific strength and specific elastic modulus. Thus, the weight is made light and the resonance sound of material at high frequency range is suppressed.

Title: Water tube boiler and combustion method thereof
Inventor: MOGI TORU
IPC: F22B31/00
Filed: 1995-11-20
Abstract: PROBLEM TO BE SOLVED: To attain a low CO combustion without changing the size of a combustion chamber in a water tube boiler which uses jet flames. SOLUTION: This invention relates to a water tube boiler where groups of water tubes 3a to 3e are laid out in rows in a combustion chamber 1 in which jet flames are formed. The groups of water tubes are provided with a wall surface which adjoins with the combustion chamber and or an area whose spacing with each water tube is sparsely formed in its cross section which intersects with the jet direction of the jet flames. At least in the space area Sa, which is sparsely formed, are continuously formed from the upstream side of flames of the water tube groups to the downstream side.  In the space area Sa whose spacing is provided between the water tube groups 3b and the water tube groups 3g and which is a sparsely formed area, a recirculating current of a high temperature combustion gas (in the arrow direction) is generated, which is subjected to a following wake of the jet flames in which the spacing of the water tubes is produced in a dense area. This inhibits a sharp drop in the temperature of the jet flames, which makes it possible to transfer the jet flames to the downstream in the state which maintains the oxidative reaction temperature which ranges reportedly from 1000 deg.C to 1500 deg.C. This constriction makes it possible to promote the oxidative reaction of CO and reduce the residual CO in the exhaust gas dramatically.

Abstract: PURPOSE:To prevent generation of defects on the inside surface of a stock pipe after piercing by inserting a plug into the solid billet in the direction not against the V-segregation zone therein and piercing and rolling the solid billet at the time of piercing the as-cast solid billet obtd. by continuous casting. CONSTITUTION:Upper and lower cross helical rollss 1 are disposed in the directions opposite from each other with respect to the pass line in which the billet 2 passes in the form of a hollow stock pipe 3. The revolving shafts of these rolls are inclined by an angle beta and the rolls are driven in the same direction. An easy-to-bore state is created in the solid billet 2 by the effect of the angle beta of inclination when the billet 2 heated to a prescribed temp. enters the rolls from an arrow direction 5. The billet 2 is bored by the plug 6 set therein, by which the hollow stock pipe 3 is formed. The billet 2 is inserted into the rolling region in the state in which the V-segregation zone of the billet has a recessed shape with respect to the plug 6, i.e., in the direction where the V-segregation zone of the billet is not against the plug 6, then the billet is bitten into the rolls and is rolled, by which the generation of the flaws on the inside surface of the stock pipe 3 is prevented.
