Title: Manufacture of vinyl chloride polymer for paste
Inventor: MURASE YASUO
IPC: C08F2/44
Filed: 1987-09-16
Abstract: PURPOSE:To produce the title polymer which gives a plastisol low in viscosity and excellent in, for example, flowability, by adding a hydrotalcite to a vinyl chloride-based monomer before the beginning of or at an early stage of the emulsion polymerization of the fine suspension polymerization of the monomer. CONSTITUTION:Vinyl chloride alone or a mixture of vinyl chloride and a monomer copolymerizable therewith (e.g., ethylene) is subjected to emulsion polymerization or fine suspension polymerization. At that time, a hydrotalcite is added to the vinyl chloride-based monomer before the beginning of or at an early stage (at the stage of conversion of 50% or below) of the polymerization to produce a vinyl chloride polymer for pastes. It is preferred that the hydrotalcite is previously emulsified using a surface active agent (e.g., a higher fatty acid ammonium salt) and then added to the monomer. The obtained vinyl chloride polymer can be used to produce a product excellent in whitening upon absorption of water and excellent in heat stability, and can be advantageously used, especially, for manufacturing a transparent product such as a flooring surface layer.

Title: Phase control circuit for electronic transformer, lighting circuit and lighting system using these circuits
Inventor: KITAMURA NORIYUKI
IPC: H05B39/08
Filed: 1992-08-31
Abstract: PURPOSE:To light an incandescent lamp in a dimmed condition without any blink by causing an LC parallel resonance circuit to alleviate a flow of large rush current occurring at the time of turning on a dimmer for phase control to the side of an electronic transformer, and preventing the commutation of the dimmer. CONSTITUTION:A blink preventing LC parallel resonance circuit 6 comprising an inductor L and a capacitor C, is connected in series to the output side of a dimmer 5, thereby forming a phase control circuit 7 for controlling an electronic transformer 3. In this case, the resonance frequency of the circuit 6 is set at such a value as exactly or approximately agreeing to a harmonic component appearing at the time of turning on the dimmer 5. Also, impedance is set to be infinite in the vicinity of the resonance frequency. In this case, even when the dimmer 5 is turned on and rush current occurs due to the sudden start of operation thereof, the circuit 6 generates infinite impedance in the neighborhood of the frequency of the current, thereby alleviating and preventing rush current to the capacitor C1, C2 or the like of the electronic transformer 3. As a result, commutation for repeatedly turning on and off the dimmer 5 can be prevented, and blink at the time of lighting a lamp can also be prevented.

Title: Ink ribbon mechanism of printer
Inventor: FUKUMA KAZUO
IPC: B41J35/14
Filed: 1988-09-19
Abstract: PURPOSE:To make possible printing at high density with an ink ribbon, if necessary without replacement of a ribbon cassette by providing a ribbon traction mechanism for the vertical movement of the ribbon cassette and allowing each upper and lower part equal to 1/3 of the entire width of the ink ribbon to be repetitively used with the help of a mobius ring. CONSTITUTION:An ink ribbon in a ribbon cassette 3 is connected endlessly in the form of a mobius ring, so that the ink ribbon can be repetitively used. The ribbon is wider than the conventional ribbon and used by dividing the width into three parts, upper 4, intermediate 6 and lower 5. When printing is performed in a convetional manner, the upper part 4 and the lower part 5 of the ink ribbon are alternately used. Thus the printing is achieved by the same ink ribbon repetitive use method as by the conventional method. In this state, the intermediate part 6 is not used and therefore, a state where it is possible to perform printing at an initial density, is maintained as it is. As long as this ribbon cassette is used, high-density printing can be performed using the intermediate part 6 of the ink ribbon by activating a ribbon traction mechanism to move the intermedicate 1/3 part of the ink ribbon to a use position, if important documents need to be printed.
