Title: Production of vinyl chloride-based polymer
Inventor: OURA MAKOTO
IPC: C08F2/00
Filed: 1997-10-30
Abstract: PROBLEM TO BE SOLVED: To produce the subject polymer capable of effectively preventing polymer scales from depositing and having high productivity by polymerizing a vinyl chloride monomer or the like in the presence of a specific condensed phosphoric acid-based compound in an aqueous medium using a polymerization initiator. SOLUTION: Vinyl chloride monomer or a vinylic monomer mixture consisting essentially of the vinyl chloride monomer is (co)polymerized in the presence of a condensed phosphoric acid-based compound having >=600 weight-average molecular weight (e.g. a linear condensate or a cyclic condensate) in an amount of preferably 25-200 ppm based on the monomer in aqueous medium in a polymerizing vessel having preferably >=80 m<3> internal volume by using a polymerization initiator (e.g. diisopropyl peroxydicarbonate or potassium persulfate) in an amount of 0.01-0.2 pt.wt. based on 100 pts.wt. monomer. Thereby, the objective polymer is produced. A coating film composed of a polymer scale deposition inhibitor is preferably formed on the inner wall surface of the polymerizing vessel and a part brought into contact with the monomer during the polymerization.

Title: Electro-transfer recording device
Inventor: SANO TETSUHIRO
IPC: B41J2/355
Filed: 1987-12-11
Abstract: PURPOSE:To reduce the number of recording electrodes to be simultaneously electrically conducted, to stabilize an electric current, and to eliminate irregularities in density and size, by a method wherein, only a plurality of recording electrodes arranged in a line are brought into pressure contact with an ink ribbon, a control circuit conducts a time-sharing drive simultaneously driving the aforesaid recording electrodes at every N-pieces, and all the undriven recording electrodes are electrically grounded. CONSTITUTION:A control circuit 5 conducts a time-sharing drive of electrodes at every N-pieces. In the first example, the case with N=3 is described. When the control circuit 5 is actuated and thereby predetermined transistors 2 or 3 are turned ON, a recording current passes from recording electrodes 1 with the transistors 2 turned ON through a path shown by a broken line. As a result, a resistant layer 7 just under the recording electrodes generates Joule heat, whereby an ink layer is melted to be transferred to a recording paper. Usually, either of the transistors 2 or 3 connected to the recording electrodes 1 are turned ON. Because the recording electrodes with the transistors 2 ON is smaller in number than the recording electrodes with the transistors 3 ON, an electric current converges just under the former recording electrodes and thus the ink on the appropriate part is transferred.

Title: Control device for power steering device for car
Inventor: ETO KUNIHIKO
IPC: B62D117/00
Filed: 1989-12-04
Abstract: PURPOSE:To prevent the steering from becoming heavy at the time of steering hold by furnishing a control means to put the steering-back control out of effect in case the steering angular velocity is smaller than the specified value and is decremental during the steering-back in low speed operation. CONSTITUTION:In case the steering angular velocity theta is smaller than the specified value A1 during steering-back in low speed operation, the current impressed on a solenoid control valve 30 is put identical to the base current I as determined from the car speed v and the steering angle theta, and thereby decrease of the return control current IH is stopped. In case the steering angular velocity thetahas been decreased, the current impressed on the solenoid control valve 30 is increased gradually to the base current I, and thereby the assist force is controlled in the direction of enlarging, which should ensure that the steering will not become heavy at the time of steering hold. In case the return control current IH is calculated to the output current IO, change will be made gradually by the use of steering angle, so that there is no more steep change in the assist force, which should eliminate presence of foreign sense.

Filed: 1994-12-19
Abstract: PURPOSE: To provide a power factor improvement device which can control the number of applied capacitors in order to keep a target power factor regardless of the operating state of a receiving/transforming equipment. CONSTITUTION: A computing element 10 calculates a power factor based on the active power value P0 and the reactive power value Q0 received from a power measuring device 9 and outputs an applied capacitor decrease command 12 and an applied capacitor increase command 11 when the present power factor is larger and smaller than the upper and lower limit value of the control range of the target power factor respectively. Then an applied capacitor controller 13 turns on or off one of electromagnetic contactors 6 of capacitors C1 to C5 . Furthermore, the number of applied capacitors are controlled before the power factor gets out of its control range when the element 10 decides that the changing rate of the value Q0 set to the power P0 per unit time is larger than a reference changing rate even if the present power factor is included in its control range.

Title: Cold heat environment testing device
Inventor: OZEKI HIROYUKI
IPC: G01N17/00
Filed: 1989-12-06
Abstract: PURPOSE:To shorten a temperature return time of low temperature exposure by a method wherein when heat stored in a cold storage device completes heat-exchange with the retention heat of a sample, the cold storage device is closed by means of a wind direction control plate to turn the flow of air to the cooler side. CONSTITUTION:A subdamper 25 is mounted to the outlet of a cold air bypass passage 16 in a low temperature room 2. The subdamper is turned, as shown by a solid line, to a direction exteding along the cold air bypass passage 16 during previous operations, precold operation, and a return to a low temperature, and cold air passes through a cold storage device 14. Since the subdamper 25 is caused to fall in the direction of a broke line at a point of time when low temperature exposure operation is started and temperature in a low temperature room 2 is increased to a value approximate equal to temperature in a test room 1, cold air flowing from the test room 1 through a cold air discharge port 5 to the low temperature room 2 flows directly to a vaporizer 12 since the cold storage device 14 is closed by the subdamper 25. In this case, since a quantity of heat stored in the cold heat storage device 14 is reduced to zero and a test in the test room 1 and that in a room are a similar excessive thermal load, by separating the cold storage device 14, being a thermal load, by means of the subdamper 25, efficiency is improved.
