Title: Electron gun and cathode-ray tube
Inventor: YAGUCHI TOMIO
IPC: H01J29/48
Filed: 1996-04-26
Abstract: PROBLEM TO BE SOLVED: To restrain generation of unnecessary electron beam emission so as to provide the electron beam having high energy and high convergence without deteriorating controllability of an electron beam by forming, on a control electrode, a surface layer having hardness higher than that of an undercoat material. SOLUTION: In a highly hard surface layers 17, 18, chromium, molybdenum and vanadium are added in the vicinity of the surfaces of control electrodes 7, 8. Formation of the surface layers 17, 18 at the surfaces of the electrodes 7, 8 can control generation of flaws in assembling an electron gun, thereby enhancing the breakdown voltage characteristics of the electrodes 7, 8, to thus restrain generation of unnecessary electron emission. Since the material of the electrode remains inside even if the coating films 17, 18 are formed in this way, the properties of the material can be maintained. Particularly in the case of an iron-nickel alloy, dimensional accuracy of the electrode can be kept high because of its small thermal expansion coefficient. Consequently, an electron gun constituted of the control electrodes 7, 8 can provide an electron beam having high energy and high convergence.

Title: Terminator for coaxial network
Inventor: TANAKA SATOSHI
IPC: H03H7/38
Filed: 1985-05-20
Abstract: PURPOSE:To match the impedance to a low frequency band signal of a base band by connecting a termination circuit exclusive for high frequency signal in parallel with a termination circuit exclusive for base band constituted by using a variable resistor. CONSTITUTION:A high frequency signal inputted from a termination connection terminal T is terminated with a characteristic impedance by using a termination resistor R1 via a capacitor C1 for base band signal cut-off. On the other hand, the low frequency signal of the base band passes through a coil L1 and a DC cut-off capacitor C2 has a capacitance enough to pass a low frequency signal of base band, the base band signal is terminated by a variable resistor VR1. Thus, the entire impedance of the network at a low frequency signal is adjusted by using the termination variable resistor and the terminator is switched in common for the high frequency terminator and the base band terminator by using a switch SW1 connected in series with the variable resistor. Thus, the impedance matching to the base band low frequency is attained easily.
