Filed: 1977-10-12
Abstract: PURPOSE: To make it possible to write signals without causing any error in a memory when the sudden variation in horizontal synchronous period occurs in TV signals, by forcing the output phases of an automatic phase control circuit to synchronize by an input horizontal synchronizing signal.  
     CONSTITUTION: Before the head of a simple VTR is changed over, the instruction which holds the control voltage of the voltage control oscillator of automatic phase control circuit 10 is transmitted from field counter 11 to circuit 10 so as to hold the control voltage, so that the sudden variation in horizontal synchronising signal period occurs, the oscillation frequency of circuit 10 well not change suddenly. Then, information of several lines about the time of the sudden variation in horizontal synchronising signal period is written to memory 5 with its phase made different, but no error occurs to data previously written. In addition, the output phase of circuit 10 after a control-voltage holding interval is forced by an input horizontal synchronizing signal to synchronize, so that the sudden variation in control voltage can be prevented

Title: Plate member suction device
Inventor: YAMADA TADASHI
IPC: B65H3/08
Filed: 1986-05-27
Abstract: PURPOSE:To automatically keeping vacuum in suction pads even if a shape and arrangement of plate members change, by mounting a plurality of the pads on a moving frame capable of moving vertically and providing an electro magnetic valve and a vacuum gauge with each of the pads. CONSTITUTION:When a plate member 2 which is smaller than a plate member of maximum size is to be sucked, there are suction pads 8 which are held in abutment against the plate member 2 and suction pads 8 which are not held in abutment against the plate member 2, which is different depending on a size and arrangement of the plate. When vacuum is applied to all of the suction pads at the time, the vacuum pressure in the suction pads which are not held in abutment against the plate member 2 cannot be reduced to a prescribed value. Therefore, an electromagnetic valve 9 connected to the a vacuum gauge 10 is actuated by the vacuum gauge 10 for closing. With this arrangement, the suction pads 8 which are not held in abutment against the plate member 2 is closed so that the suction pads 8 are prevented from sucking atmospheric air and only the suction pads 8 held in abutment against the plate member 2 work effectively. As a result, suction operation can be effected automatically even if an operator does not open or close the electromagnetic valves.

Abstract: PROBLEM TO BE SOLVED: To obtain high-purity indene useful as a raw material for medicines, agrochemicals, etc., by effectively removing benzonitrile contained in indene- contg. tar-based light oil in a simple operation. SOLUTION: A solid alkali (e.g. anhydrous potassium hydroxide) is added to an indene-contg. tar-based light oil such as tar light oil fractionated from coal tar or heavy light oil fractionated from coke oven gas light oil followed by a treatment under heating pref. at 160-200 deg.C, and insolubles deposited is removed, followed by conducting a distillation. The amount of the alkali to be added is 1-3 molar times the benzonitrile contained in the light oil. The alkali to be used is flaky or in the form of pellets, being pref. anhydrous; if an aqueous alkali solution is used instead of solid alkali, removal of the benonitrile becomes insufficient.
