Title: Activation of chromium-based fluorinated catalyst
Inventor: AOYAMA HIROICHI
IPC: C07C17/00
Filed: 1988-04-13
Abstract: PURPOSE:To recover activity of a catalyst without affecting hydrogen atoms contained in a raw material by stopping feed of the raw material at a point of time when reduction of catalyst activity is recognized in a fluorinating reac tion process and feeding the gas incorporating oxygen. CONSTITUTION:In activation of a catalyst in the fluorinating reaction of hydrogen-contg. halogenated hydrocarbon, especially of chromium-based fluorinated catalyst, activity reduction of the fluorinated catalyst is recognized in a reaction process. At this time, feed of a raw material such as CCl2=CHCl and hydrogen fluoride is stopped. The catalyst is activated by feeding the gas incorporating oxygen to the reaction system. After activation, feed of the gas incorporating oxygen is stopped and the raw material is refed. By such a way, activity of the catalyst is completely recovered without affecting hydrogen atom contained in the raw material.

Title: Synchronizer
Inventor: CHIYAARUZU MAACHIN WAIN
IPC: G06F1/04
Filed: 1985-05-01
Abstract: A computing means (23) is provided which has its instruction execution synchronized to a reference signal (HFB). The computing means (23) executes instructions in instruction cycles synchronously related to a clock signal. The clock signal is generated by means (37, 45) which can control its phase and frequency in response to a control signal. The computing means (23) generates a comparison signal each time a nredetermined number of instruction cycles have occurred. A comparison means (51, 53) compares the phase and frequency of the comparison signal to that of a reference signal (HFB) from a source (19) and generates the control signal in response.The computing means may be a microprocessor used to disetay characters on the display (17) of a television. The reference signal is then a television synchronizing signal (HFB) from a source (19) so that the instruction cycles are synchronized with the television synchronizing signal HFB). The microprocessor (23) generates character pulses at a rate pro- portronal to the instruction cycles from data signals corresponding to the chatacter from a source (33). Means (25, 15) couple the character puises to the display (1 7) to display the characters.
