IPC: H01J9/18
Filed: 1981-04-07
Abstract: PURPOSE:To measure the eccentric amount of the grid-electrode hole of a color- television electron gun with high accuracy by measuring the said eccentric amount optically by using both the method of imaging the grid-electrode hole by use of transmitted illumination light, and the method of imaging the grid- electrode by reflecting irradiated illumination light with an inserted reflection- plate according to the condition of the electrode hole. CONSTITUTION:Illumination light emitted from a light source 13, after being transmitted by grid-electrode holes (a-f) of an electron gun 10, enters into an imaging optical device 5, enters through an objective lens 19 and half mirros 16a, 16b, 16c and 16d into a first light path (P1), and travels through a lens 17a of the path (P1) into a visual sensor 4. Following that, hole images caught by the visual sensor 4 are passed through a controller 20, and are subjected to information processing by means of an arithmetic unit 21 and a monitor 22. Thus, the center eccentric-amount of the above electrode hole (e) is given by comparing it with the center coordinate of the hole image of a first grid-electrode 1a which is formerly computed. Consequently, highly accurate measurement of the accentric amount is enabled.

IPC: H04N9/74
Filed: 1980-04-22
Abstract: PURPOSE:To eliminate a frequency shift at a switching point between two video signals as to the SECAM system by controlling the phase of one of two video input signals and by performing switching operation when both the video signals are in phase with each other. CONSTITUTION:As video signals A and B are applied to input terminals (x) and (y), phase comparing circuit 3 compares the phase of output signal A(tau) of delay circuit 1 with that of signal B at the generation timing of sampling pulse SP outputted from pulse generating circuit 2. Then, phase control signal D having the voltage value that corresponds to the phase difference is supplied to circuit 1 and switch circuit 4. Signal A(tau) delayed by circuit 1 is supplied to circuit 3, which finds the phase difference from signal B again. The moment the phase difference between signal A(tau) and signal B becomes zero under the said phase control, circuit 3 outputs signal D showing that. Consequently, circuit 4 selects signal A instead of signal B and outputs it as a composite video output. As a result, signal C has no waveform distortion at a switching point.

Title: Congestion controlling method of storage exchange system
Inventor: FUNAKI TOSHIROU
IPC: H04M3/38
Filed: 1979-04-27
Abstract: PURPOSE:To prevent the storage of the incoming incapable signal within the communication network for the new call which is going to give the communication to the signal passed through the storage exchange device under congestion, by selecting the passing route or regulating the originating. CONSTITUTION:For instance, if the congestion occurs in storage converter 21, the congestion is detected by congestion detector 21 and then displayed on congestion state display units 47, 61 of detector 21 and adjacent telephone exchange 17. Under these conditions, when the subscriber A dials the number through telephone 11, the number is transmitted to exchange 17 via subscriber line exchage 13. Exchange 17 discriminates converter 21 in the congestion state based on the dispaly state of unit 61 and then selects storage converter 22 which is not under congestion for connection. In this case, if no other stroage converter can be selected, the originating control is given. Then with calling of subscriber B through telephone 14, telephone exchange 18 discriminates exchange 17 of the incoming side to refer to unit 61 of exchange 17 by means of common signal line units 27 and 28. The same treatment is given subsequently.
