Title: Surface treatment of shadow mask
Inventor: HATTORI MUTSUMI
IPC: H01J9/14
Filed: 1986-08-25
Abstract: PURPOSE:To obtain a color cathode-ray tube high in color purity, by making a surface on an electron gun side of a shadow mask be turned upward and keeping an atmosphere in high humidity and setting up the distance from a sprayer to the surface of the electron gun side in such a value that an atomized coating liquid is capable of naturally dropping on the surface of the electron gun side. CONSTITUTION:Because disturbance of an air current occurs at the time of spraying a coating liquid 11 from a nozzle 10, the distance from a sprayer to a coated surface 4a is set up large enough to prevent the disturbance of the air current in the vicinity of the surface 4a. A speed of the liquid is lowered to a speed at which the liquid naturally falls by its own weight. Therefore, the liquid is not sticked on inner walls of electron beam passing holes of a shadow mask 4, but passes through the holes without obstacles being generated in the holes. Because the atmosphere is kept in high humidity by the use of a gas from a duct 12, the liquid 11 is not dried midway but is sticked on the surface 4a,and then is dried for long hours. Therefore, the peripheral part of the holes 5 of the coated film 6 becomes thinner than the other part so that an orbit of electron beams is not interrupt.d and the beams are not scattered. Thus, a color cathode-ray tube high in color purity can be obtained.

This observation value is regarded as th electric DC offset value to be included in a servo control circuit, and in order to eliminate this offset, a correction offset corresponding to the DC offset value is given to the amplifier 8. By this method, the electric DC offset contained in the servo control circuit is eliminated, thus performing the accurate servo control.

Patent JP-H0865886-A (JP)
Title: Power supply circuit
Inventor: ITO SHIN
IPC: H02H9/02
Filed: 1994-08-25
Abstract: PURPOSE: To make a.DC power supply like a battery small and low cost. CONSTITUTION: A series circuit made of a resistor R and a capacitor C in series is connected across input terminals. A current detection element SQ and a constant-voltage threshold element D in series are connected in parallel with the capacitor C. A switch element S is connected between an input terminal IN1 and an output terminal OUT1 , and a switching element S2 is connected between a connection point of the resistor R and the capacitor C and the output terminal OUT1 . When a power switch S is turned on and a capacitor voltage Vc rises above a given level Vr, a current is carried at the constant-voltage threshold element D. Then, the switch elements S1 and S2 are turned on by the current detection element SQ immediately when the current is detected. A DC power supply P is connected to a load L, and thereby the charge in the capacitor C is discharged concurrently. The DC power supply P generates always a normal-state current that is enough for the load because a rush current necessary for the rise of the load is almost all fed by the capacitor C.

Title: Bolt fastening structure
Inventor: SAKUTA TAKUJI
IPC: F16B5/02
Filed: 1997-07-25
Abstract: PROBLEM TO BE SOLVED: To provide a bolt fastening structure at a low cost which can reliably prevent shear directional (in the direction in mutual contact planes) positional dislocation of a machine part to a base stand. SOLUTION: In a bolt fastening structure to fix a machine part 2 to a base stand 1 by using a bolt 6, a thin plate 7 whose both surfaces are formed in a recess projection shape and which is formed of a construction material harder than the base stand 1 and the machine part 2, is interposed between the base stand 1 and the machine part 2. When a bolt 6 is strongly fastened, a projecting part 7a of both surfaces of the thin plate 7 harder than the base stand 1 and the machine part 2 bites into contact planes 1a and 2a of the base stand 1 and the machine part 2, and therefore, shear directional frictional force increases between the base stand 1 and the machine part 2 through the thin plate 7.  Since rounding work 8 is also performed on an external shape end part of the thin plate 7, a stress concentration in a part of the base stand 1 and the machine part 2 contacting with this external shape end part is relieved, and a fatigue crack is hardly caused in the base stand 1 and the machine part 2.

Abstract: PURPOSE:To improve the stability of time base correction by providing a circuit attenuating an error signal with a vertical synchronizing signal of a video signal to the time base correction circuit for a video signal of a video reproducing device for a device such as an LD player. CONSTITUTION:A phase difference signal from a burst phase comparator circuit 1 is sampled and held by a sample-and-hold (S/H) circuit 2 in a timing of a burst gate signal and the result is outputted as an input signal to an adder through a resistor R1.
