Title: Production of oligomers by solid-phase polymerization of m-isopropenylphenol
Inventor: MATSUSHIMA SHIYUNSUKE
IPC: C07C37/00
Filed: 1978-04-04
Abstract: PURPOSE: The solid-phase polymerization of m-isopropenylphenol gives a mixture of oligomers with relatively high polymerization degree that are used as raw materials for epoxy and novolak resins with excellent mechanical properites.  
     CONSTITUTION: The solid-phase polymerization of m-isopropenylphenol is conducted to produce a mixture of oligomers containing a relatively large amount of oligomers with high polymerization degree. The solid-phase polymerization gradually advances in the crystals of the raw material; however, when a catalyst is mixed in the crystals or made to contact with the surface of crystals, the polymerization rate is relatively accelerated. In order to add the catalyst into the solid phase crystals, m-isopropenylphenol is molten or dissolved in a solvent and a catalyst as  boron trifluoride is added, then the system is rapidly cooled or the solvent is rapidly  evaporated to reprecipitate the crystals. The resulting oligomers is presumed to  have the structure of formula I (n is 0, 1, 2, ....).

IPC: H02M3/155
Filed: 1980-03-31
Abstract: PURPOSE:To obtain the DC regulated circuit having a wide input voltage range, by controlling the voltage control circuit with the output signal of a rectangular wave oscillator. CONSTITUTION:Transistors (TR)Q1, Q4 are used as voltage controlled element, resistors R1-R4 and TRQ2 act like auxiliary operation of the switching of TRQs1, Q4. If the voltage dividing the output voltage with resistors R5 and R6 is smaller than the reference voltage 3, the number of pulses appeared at the output of the rectangular type oscillator 2 is increased, the period of on/off is decreased for TRQs1,Q4, the energy stored in the inductor L is output one after another and the output voltage is increased. If the voltage dividing the output voltage with the resistors R5, R6 is greater than the voltage 3, the output voltage increases on the contrary. Thus, the DC regulated circuit having wide input voltage range can be obtained.

Filed: 1995-02-28
Abstract: PURPOSE: To exactly and speedily perform station decision at the time of tuning at all times by composing the synchronizing detection circuit of a PLL circuit, horizontal counter, horizontal/vertical synchronizing detection circuit and station deciding counter. CONSTITUTION: A PLL circuit 11 generates a basic clock OSC by comparing the phase of a composite synchronizing signal CSYNC with that of a phase signal PH fed back and inputted from a horizontal counter 14. Corresponding to this basic clock OSC, the horizontal counter 14 generates a mask signal HWIN for masking a horizontal synchronizing signal HSYNC in the signal CSYNC and applies it to a station deciding counter 13. A horizontal/vertical synchronizing detection circuit 21 detects a vertical synchronizing signal VSYNC from the signal CSYNC, applies it to the station deciding counter 13, detects a horizontal synchronizing signal HSYNC and applies it to the station deciding counter 13 as an operating clock. Therefore, even when the signal CSYNC is distorted or any noise is superimposed, all the noises, etc., are absorbed by the circuit 21.

Abstract: PURPOSE: To prevent the thickness deviation of the hollow shell, by arithmetically forecasting the temperature distribution in the cross section of a round billet extract from the heating furnace, by obtaining the maximum temperature deviation from the result of said operation, and by taking suitable measures for controlling the thickness deviation.  
     CONSTITUTION: A round billet 10 is charged into the heating furnace 12 by the charger 11 and is heated to high temperatures while being passed through each zone by the rotating furnace floor driven by the motor 16. Hereupon, the computer operates the temperature distribution in the cross section of the round billet 10 on the basis of such data as the furnace temperature of each zone measured by thermocouples 15, the steel grade of the billet 10, the size, etc., and the prescribed data stored in the memory file of the computer. From the result of this operation, if the maximum temperature deviation is judged larger than the first reference value, the heating condition is changed; and if the temperature deviation is larger than the second reference value larger than the first reference value, the extraction of the billet 10 from the furnace 12 by the extractor 13 or the piercing work by the piercer 14 is interrupted. Hereby, the rate of thickness deviation of the hollow shell 10' is controlled to under the prescribed value.
