Abstract: PURPOSE: To obtain the titled polymer having improved rigidity and thermal stability, by washing a slurry prepared through liquid phase polymerization of propylene etc. in the presence of a catalyst consisting of titanium trichloride and an organoaluminum compound with a liquid phase monomer in the presence of an epoxide countercurrently to remove a solvent-soluble polymer and the catalyst residue.  
     CONSTITUTION: Polymerization of propylene or copolymerization of it with another unsaturated hydrocarbon monomer is carried out in the liquid phase propylene in the presence of a catalyst consisting of (A) titanium trichloride which is prepared by reducing titanium tetrachloride with an organoaluminum compound, and activating the reduction product and (B) an organoaluminum compound. The resultant polymer slurry is taken out of a polymerizer 1, and fed to the top 8 of a countercurrent washing tower 7. The slurry is washed with a liquid phase propylene fed from the bottom 9 of the washing tower 7 countercurrently while feeding an epoxide, e.g. propylene oxide, to the intermediate point 17 of the washing tower 7. The polymer deposited in the bottom of the tower 7 is passed through a reducing valve 12, taken out of a line 11 to a tank 13 continuously and separated to give the aimed powdery polymer.

Title: Information signal recording and reproducing device
Inventor: SUGIHARA MOTOOKI
IPC: H04N5/92
Filed: 1991-05-20
Abstract: PURPOSE:To realize good reproduction by recording a discrimination signal to a horizontal line on the time bases different from each other in neighboring tracks when a divided video signal is recorded on the track of a recording medium together with a video format discrimination signal. CONSTITUTION:A code signal supplied to a multiplex circuit 2c is inserted into a horizontal n-th line in the vertical blanking of the video signal of a channel C by a control signal from a multiplex control circuit 5. Similarly, the code signal is inserted into the (n+1)-th and (n+2)-th lines in the vertical blanking of the channels B, A from the multiplex circuits 2b, 2a. These multiplexed video signals pulse-convert three light beams to irradiate the neighboring tracks A, B, C of a disk 7 from a light beam irradiator 6d, and produce the format in which the code signal is positioned at the horizontal line position on the time bases different from each other. Accordingly, even if drop-out due to a flow or soil, etc., occurs, it is compensated by the discrimination signal, and the good reproduction of an original format signal can be performed.

Filed: 1979-09-10
Abstract: PURPOSE:To improve conversion efficiency by removing influence of electrostatic capacity by connecting the piezoelectric element side of a coil spring to the cable conductor of an MI cable electrically and by adequately selecting the inductance of the coil spring. CONSTITUTION:The lower end of the conductor of MI cable 6 is electrically connected to the lower end of coil spring 5 and electrode plate 3 and spring 5 is connected in parallel to piezoelectric element 2.

Abstract: PURPOSE:To ensure offset of penetrating magnetic flux with third harmonic wave current, by winding superconductors at the upper and the lower parts of an iron core having three legs in a three-phase transformer, or mounting the superconductors in a planar pattern. CONSTITUTION:Third harmonic waves are outputted from an iron core 1. A superconductor 2 is formed in one turn. The superconductors 1 are mounted on the surrounding part of the upper and the lower parts of the iron core 1. Or the superconductor is mounted on one part. Or the outgoing parts of the harmonic waves are covered with superconductive flat plates 6 and 7. When magnetic flux is going to pass through the superconductors 2, induced electromotive forces are generated and currents are made to flow. Thus, offsetting magnetic flux is generated. It is necessary to provide a conductor having the number of turns or the cross sectional area which is equal to ampere turns forming said magnetic flux in order to make the outgoing magnetic flux zero. When this is performed with the superconductor, the magnetic flux can be offset with the thin conductor.

Abstract: PURPOSE:To simplify a circuit constitution and to attain the miniaturization and circuit integration of a circuit by combiming two amplifiers, plural switch elements and a constant voltage source. CONSTITUTION:A PCM signal is sequentially inputted from the least significant bit from a terminal (d). The 4th analog switch 4 is controlled by the PCM signal to turn on/off the integration current conducted from the constant voltage source 5 to an amplifier 7 via a resistor R5.

IPC: H03K3/037
Filed: 1981-07-23
Abstract: PURPOSE:To perform high speed operation, by decreasing the number of stages of gate circuits at the input side of a shift register. CONSTITUTION:When a trigger input T goes to H level, a transfer gate T4 is opened and a signal at output terinal -Q is transimitted to an input terminal of a shift register 10. Since this signal passes through the register 10 with clock pulse CP and inversion CP', a signal at an output terminal Q is inverted. When the input T goes to L level, an output of an inverting circuitI4 goes to H level, a transfer gate T3 is opened and a signal at the output terminal Q of an inversion circuitI3 is applied to the input terminal of the register 10. Since this signal passes through the register 10, the output terminal Q keeps the state as it is. That is, since this circuit performs the operation of T type FF, before a signal at the output terminal Q or -Q reaches the register 10, the circuit constitution is made to pass through the gate T3 or T4, allowing to perform high speed operation.

Abstract: PURPOSE:To simplify a mechanism for setting and removal of tools by installing a draw bar depressing arm having an energization spring, which presses the draw bar downward, when cam is in service, and separates from the top of this draw bar when the cam is out of effect. CONSTITUTION:In order to replace tool, a spindle head 10 is raised to allow a roller 30 of a draw bar depressing arm 24 to override a cam 28 so as to push down the draw bar 18 by the depress end-part 24a of said arm 24. Thereby the tool is released from a tool receptacle 16 of the spindle 14.
