Patent JP-H0232765-A (JP)
Title: Power converter
Inventor: NISHIZAWA YUJI
IPC: H02M7/537
Filed: 1988-07-19
Abstract: PURPOSE:To shorten the opening time of an output voltage by deciding the short-circuit state of upper and lower two output elements of an output circuit and by correcting a short-circuit prevention time on the basis of said short- circuit state. CONSTITUTION:A voltage-type inverter is composed of a DC power supply 1, a signal generator circuit 2, a short-circuit prevention time generator circuit 3, switching elements 7, 8, etc. Also, said inverter is provided with an upper and lower short-circuit decision circuit 12 by a current sensor 10 and a comparator 11, and an upper and lower arm short-circuit prevention time (TD) correcting circuit 13 by a counter. Thus, when an upper and lower short-circuit occurs, the output of said comparator 11 is reversed and the state of an upper and lower short-circuit is decided, and the signal a7 of said state is transmitted to said TD correcting circuit 13. Said circuit 13 detects that the time TD is too short, increases the TD set value 4 by the time corresponding thereto, and transmits it to the TD generator circuit 3. As a result, said upper and lower short-circuit is suppressed by repetition of said process and the time TD becomes the shortest so that the opening time T0 at the output end also becomes short.

Title: Manufacture of raw polyester master polymer
Inventor: MURAI MASUO
IPC: B29C48/40
Filed: 1985-08-14
Abstract: PURPOSE:To enable to manufacture a polyester master polymer which is obtained by dispersing a pigment highly uniformly and has a high concentration of pigment, by kneading with rotational power of specific magnitude by limiting a scope of the mixture ratio between polyester and the pigment at a first step. CONSTITUTION:At the first kneading step, it is necessary to set the mixture ratio between polyester and pigment at a weight ratio of 60:40-40:60. Kneading is performed further at the second step; it is desirable to set the concentration of pigment at this time at 10-40wt%. With this construction, the dispersability of pigment can be improved and it is possible to lower the temperature of the polyester raised through shearing force at the time of kneading at the first step and to control thermal decomposition. It is necessary to make rotational power at the time of the kneading more than 0.03kW per 1kg of a kneading thing. With this construction, at the low rotational power, dispersion of the pigment becomes insufficient because of lack of shearing force. However, it is wastefulness in energy to raise the rotational power excessively and the rotational power to the extent of 0.07-0.2kW is desirable.
