Abstract: PURPOSE:To obtain a method for suspension polymerization of a vinyl chloride- based monomer in which normal polymeric particles are obtained even by operating a reflux condenser from the initial period of the polymerization; the size of a polymerizer can be increased and polymerization time can be shortened without increasing fish eye. CONSTITUTION:A polymerizer equipped with a reflux condenser (hereinafter referred to as RC) is used and the interiors of the polymerizer and the RC are preferably previously deaerated. A previously deaerated and warmed ion exchange water and a prewarmed vinyl chloride-based monomer are fed thereinto at preferably (1/1.5) to (1/0.8), more preferably (1/1.2) to (1/0.9) feeding ratio of the fed monomer/water and a dispersing agent (e.g. methyl cellulose) is further fed in an amount of 0.03-1.5 pts.wt. based on 100 pts.wt. fed monomer. The interior of the polymerizer is subsequently regulated to 40-80 deg.C. (B) A polymerization initiator (e.g. diisopropyl peroxydicarbonate) in an amount of 0.03-1.5 pts.wt. is then fed thereinto and the RC is simultaneously operated to remove the heat of polymerizing reaction. Thereby, the vinyl chloride-based monomer is subjected to the suspension polymerization with high productivity.

Title: Channel switching equipment for digital communication system
Inventor: INOUE KUNIAKI
IPC: H04B1/74
Filed: 1987-12-11
Abstract: PURPOSE:To reduce a switching time by providing a pseudo signal output circuit in cooperation with a sending end side switching circuit of each active system so as to eliminate undesired reply of an equalizer even if any interruption takes place in a bipolar signal at the changeover to a standby system. CONSTITUTION:When a channel switching signal CH-EXCH is produced, the sending end side switching circuit 11 switches a bipolar signal from the active system into the standby system, but in this case, momentary interruption of an output signal S11 takes place. On the other hand, a pseudo signal output circuit 12 generates a pseudo signal PSD-SIG to compensate the momentary interruption of the output signal S11 as soon as the channel switching signal CH-EXCH is produced and sends it to the standby system. As a result, since the pseudo signal PSD-SIG is outputted to the standby system during the momentary interruption of the output signal S11, no hit in the standby system is occurred. Thus, the equalizer in a bipolar/unipolar converter does not give any unnecessary reply and the switching time is reduced.

Title: Element substrate, ink jet recording head, and ink jet recorder
Inventor: MATSUNO YASUSHI
IPC: B41J2/05
Filed: 1997-11-14
Abstract: PROBLEM TO BE SOLVED: To control malfunction owing to deterioration of a heater and a switch and a noise by a method wherein a plurality of switching elements provided corresponding to electricity-heat conversion elements in order to drive a plurality of electricity-heat conversion elements are connected in parallel, and switching timings of respective switching elements are differentiated. SOLUTION: When at first a signal is inputted at a timing of being at an IN terminal, C1-4 signals are respectively formed by a timing control circuit. In this case where the C1 signal is equal to an IN signal, the C2 signal becomes a signal delayed by a t1 content from the C1, the C4 becomes a signal delayed by a t3 content from the C1, a switch is ON and OFF controlled according to each timing, and a current IH flowing to a load becomes a stepping waveform under an ideal state. Consequently though high frequency components contained in a rise and a fall of the current are the same ones, their amplitudes can be lessened, the amplitude of overshoot or undershoot can be restrained, and consequently a ringing phenomenon can be controlled.
