Title: Frame offset measurement circuit
Inventor: ONO KOICHI
IPC: H04L25/03
Filed: 1990-02-05
Abstract: PURPOSE:To confirm whether the specification of ANSI is satisfied or not by providing a fixed pattern generation part and a selector and measuring the offset of a reception frame and a transmission frame in a network terminal equipment-side U point by means of the reception frame and the transmission frame with fixed pattern. CONSTITUTION:A fixed pattern generation part 2 is provided, the fixed pattern composed of a binary code is generated and the selector 3 is provided. At the time of a test, the fixed pattern of the fixed pattern generation part 2 is transmitted instead of the output of scrambled transmission data from a scramble circuit 1. Thus, the detection of a frame pattern in the reception frame and the transmission frame is facilitated and the reception frame by the fixed pattern transmitted from a subscriber line terminal equipment is compared with the transmission frame by the fixed pattern returned from the network terminal equipment at the U point of the network terminal equipment. Thus, the offsets of the reception frame and the transmission frame at the U point of the network terminal equipment can be measured.

Title: Beam current control system for picture pickup tube
Inventor: KUDO KOJI
IPC: H04N5/235
Filed: 1986-02-10
Abstract: PURPOSE:To make a beam a laminar flow state and to suppress an after-image in a high light secene by increasing the second grid voltage to a cathode according to the rise in the illumination of an object, enhancing the capacity for generating the quantity of the absolute beam current of an image pickup tube and controlling for increasing the first grid voltage as well. CONSTITUTION:A saw-tooth shaped wave signal V2 converted from a signal current IS and amplified is distributed to an adder 19 and an attenuator 20. Initially, in the adder 19, the voltage added in direct current to the reference voltage EO2 of the second grid 13 is impressed to the second grid 13. In the attenuator 20, it is attenuated to the level V1 of about 1/several numbers. The output signal of the attenuator 20 has the voltage added in direct current to the reference voltage EO1 of the first grid 12 is impressed to the first grid 12 in an adder 22. When the first grid voltage Ec1 is constant, the after-image is increased by the rise of the second grid voltage Ec2. However, 1/n of the signal voltage impressed to the second grid is also impressed to the first grid, so that the first voltage Ec1 is raised and the beam current IS is decreased. Therefore, the beam does not form a cross over and the quantity of the beam can be increased under the state of the laminar flow.
