Title: Production of ring-opening polymer
Inventor: OBARA TEIJI
IPC: G11B7/2533
Filed: 1990-07-24
Abstract: PURPOSE:To obtain a ring-opening polymer of a narrow molecular weight distribution in high yields by adding a W or Mo metathesis catalyst to the reaction system during ring-opening polymerization of a norbornene monomer in the presence of a Ziegler catalyst and continuing the reaction. CONSTITUTION:A norbornene monomer (e.g. 6-methyl-1,4:5,8-di-methano-1,4,4 a,5,6,7,8,8a-octahydronaphthalene) is polymerized through ring opening in the presence of a Ziegler catalyst comprising an organometallic compound of group I-III metal (e.g. triethylaluminum) and a titanium tetrahalide (e.g. TiCl4) to a conversion of at least 60%, and a W and/or Mo metathesis catalyst (e.g. WCl6 or MoCl5) is added to the reaction system to continue the ring-opening polymerization. According to the above process, a ring-opening polymer of a narrow molecular weight distribution can be obtained, and the obtained polymer has a very low concentration of the monomer remaining in the reaction system when the polymerization is finished. A product of hydrogenation of this ring-opening polymer has excellent moldability and low birefringence, so that it can be desirably used for optical discs, optical lenses, etc.

IPC: F23C99/00
Filed: 1983-10-21
Abstract: PURPOSE:To prevent the occurrence of blow-off of a flame, to increase a reduction rate of NOX, and to stabilize a flame, by a method wherein a flame holding surface, which is gradually increased in a calibar toward a furnace, is formed at the forward end of a fuel injection tube, and this causes a primary gas injection nozzle also to be opened so that the fuel is dispersed outwardly. CONSTITUTION:After a mixture flow of pulverized coal, fed through a pulverized coal pipe 3, and a primary air carrying the pulverized coal is uniformized with the aid of a venturi 4, it is fed in a furnace 16 through a primary injection nozzle 17. The outer periphery of the primary injection nozzle 17 is provided with a flame holding surface 21, where a flame is stabilized. Meanwhile, an impeller 2 is located to the interior of the primary injection nozzle 17, by means of which a pulverized coal flow is deviated externally. This causes production of a reverse flow in the vicinity of the impeller 2 at the downstream part of the primary injection nozzle 17 and enables stabilization of a flame on the surface of the impeller 2 also.

Filed: 1986-08-20
Abstract: PURPOSE:To make deviation of a magnetic head from tracks small and obtain a good reproduced picture by changing the amount of operation of a shifting means to a fixed amount of operation of a driving source. CONSTITUTION:When a forward button 13 is operated, pulses are given from a driving circuit 43 to a stepping motor to make 4 step rotation and a gear 25 and a gear 36 become engaged state. The coupling pin 23b of a shaft 23 passes through a hole of the gear 25, and the number of teeth of the gear 25 and gear 31 is the same, and accordingly, a drive shaft 34 makes 1/4 rotation. When the drive shaft 34 rotates, a moving body 6 moves in the direction of arrow mark D, and a magnetic head 7 also moves in the direction D. Thus, every time the forward button 13 is operated, the magnetic head 7 moves in the direction of arrow mark D. In the case where a reverse button 14 is operated, the magnetic head 7 moves in the direction of arrow mark E. By operating the forward button 13 and reverse button 14, the magnetic head 7 can be brought into contact with an optional position of the disk 3, and video signals etc. are recorded concentrically.

Title: Speed controller for dc motor
Inventor: ISHIDA KOUICHI
IPC: H02P7/06
Filed: 1982-11-10
Abstract: PURPOSE:To suppress the variation in the speed of a DC motor due to the variation in the load torque by presuming the ripple disturbance contained in the detected speed value by a ripple observing unit. CONSTITUTION:A ripple observing unit 8 which presumes and calculates a ripple (r) existing in the output of a tachometer generator 6 is provided, the presumed ripple is added to the speed presumed by a state observing unit 7, and the presumed speed is used as an actual value signal for controlling the speed. Therefore, when the ripple (r) is correctly presumed by the unit 8, the presumed speed value becomes a signal which does not contain the ripple, and the torque presuming signal becomes that containing no ripple. Accordingly, a stable control which is not affected by the influence of the ripple can be provided.

The surface temp. of the melt contacting with the crystal is simultaneously elevated gradually to a temp. 15 deg.C higher than the temp. when the body is grown. A rapid temp. change is not given to the crystal in this way, and an increase of dislocation can be suppressed.

CONSTITUTION:A side wall part 16a of a gate electrode 16 on a drain side is formed approximately vertically. A side wall part 16b of a gate electrode 16 on a source side is obliquely formed. With the gate electrode as a mask, regions 18 and 19, which are to become low-concentration impurity regions 23 and 25 are formed. Then, a spacer 21 is formed on the side wall part 16a of the gate electrode 16 on the drain side.
