Title: Production of acrylic polymer
Inventor: KOBAYASHI OSAMU
IPC: C08F20/10
Filed: 1991-11-11
Abstract: PURPOSE:To obtain a high-molecular acrylic polymer having excellent heat resistance through the solution polymerization of a (meth)acrylic ester by adding an organic mercapto compound immediately before the completion of the reaction. CONSTITUTION:A (meth)acrylic ester (e.g., ethyl acrylate) is polymerized by solution polymerization conducted, for example, in the presence of a polymerization initiator using methyl ethyl ketone as a reaction medium at about 50-70 deg.C. Immediately before the completion of the reaction, an organic mercapto compound (e.g. butyl mercaptan) is added. Compared with the polymer obtained by a process in which the mercapto compound is added at the beginning of the polymerization reaction, the acrylic polymer obtained by this process has better heat resistance and a higher mol.wt., even though the two polymers have almost the same bonded mercapto compound content. In addition, the excellent transmitting properties inherent in acrylic polymers are not substantially impaired.

Title: Servo-controller of vtr
Inventor: IKEDA TOSHIHIKO
IPC: H02P29/00
Filed: 1988-12-19
Abstract: PURPOSE:To enable a servo-loop to follow up a desired value by reading out a bias value stored in a bias value memory, to add the value to a speed error, and by reloading the bias value stored in the bias value memory, according to the DC component of the speed error. CONSTITUTION:By an adding means 25, a bias value NBIAS stored in a bias value memory 27 is read out and is added to a speed error. By a bias value renewing means 29, the bias value NBIAS stored in the bias value memory 27 according to the DC component of the speed error is properly reloaded. In other words, when the fluctuation of the speed error is deviated to the negative side for example, then the bias value NBIAS is reloaded to be made less, and the DC component of the speed error is reduced. Accordingly, the bias value NBIAS added to the speed error by the adding means 25 is automatically regulated according to the load fluctuation of a motor 1. As a result, a servo-loop can follow up a desired value.

Title: Simulated target generator
Inventor: JIROUMARU HIROKI
IPC: G01S7/40
Filed: 1993-12-21
Abstract: PURPOSE:To generate an effective simulated target for a mono-pulse type radar by applying the prescribed relative phase difference and the relative amplitude ratio to a pair of antennas to feed transmitted signals. CONSTITUTION:A signal generating circuit 408 generates a signal having the same frequency as the received frequency. This signal is modulated with the gate signal (h) from a pulse generator 209 by a modulator 404, and it is amplified by an amplifier 407. The amplified signal is distributed into two by a distributor 406 via a switching unit 602, and the phases of the signals are controlled at the preset phase shift quantities by phase shifters 403, 503. When one of them is set to 0 deg., the other is set to theta for the relative phase difference. In a mono-pulse radar, we are confused into thinking that the emission position of the radio wave is located at another point apart from the intermediate point of a pair of antennas 400, 500. When a phase difference theta7 and the relative amplitude ratio are given to one transmitted signal, a large bearing error can be simulated.
