Title: Conductive roller
Inventor: YAMAZAKI YUJI
IPC: H01B1/20
Filed: 1995-02-22
Abstract: PURPOSE: To obtain a conductive forming roller stable to a change in impressed voltage and environmental fluctuation by adding a conductive filler to the conductive forming roller in such a manner as to satisfy specific equations. CONSTITUTION: This conductive forming roller is produced by compounding the conductive filler with rubber having a specific volumetric resistance of <=10<12> Ω.cm and is so formed as to satisfy the equation I logR>=logR0 -4, equation II logR<logR0 . In the equation I, the equation II, R denotes the resistance of the roller when the conductive filler is added to the rubber and R0 denotes the resistance of the roller when the conductive filler is not added to the rubber. The dependency of the resistance on the impressed voltage increases when the amt. of the conductive filler to be added is too large and deviates from the conditions of the equation I. The dependency of the resistance on the environmental fluctuation increases when the amt. deviates from the conditions of the equation II.  As a result, the dependency of the electric resistance on the impressed voltage and the environmental fluctuation is lessened.

Title: Mr head offset correction method and magnetic disk certifier
Inventor: MORI KYOICHI
IPC: G11B21/10
Filed: 1997-02-03
Abstract: PROBLEM TO BE SOLVED: To simply correct the offset between writing head and reading head prior to certification. SOLUTION: When a piezo actuator for detecting the offset is driven, a minor loop 104 therein is turned repeatedly without turning a large hysteresis loop. In the minor loop 104, only the voltage VQ of an arrival point is increased successively at every loop without changing the voltage Vp of a start point imparted to the actuator, and the distance between the start point and the arrival point is enlarged minutely. The test data written by a magnetic head in respective start points are read by an MR head at respective arrival points, and by comparing changes in a read-out voltage, the maximum voltage loop corresponding to an offset distance is found, and thus, the correction at the read time is performed. Since the loop is small, the processing speed is accelerated.

Title: Color picture tube
Inventor: TAKADA SEIKI
IPC: H01J31/20
Filed: 1988-02-17
Abstract: PURPOSE:To reduce the mislanding amount by forming the frame fixing part of a mask holder with a base material of a large thermal expansion coefficient, and fixing the rear end of the frame fixing part to a mask frame and an elastic pin gearing part to a panel stud pin respectively. CONSTITUTION:The frame fixing part 16 of a mask holder is formed of a base material with the thermal expansion coefficient larger than that of an elastic pin gearing part 17, and, while its rear end is fixed to a mask frame 12, the rear end of the elastic pin gearing part 17 is fixed to a panel stud pin. As a result, while the fixing part of the mask holder 13 extends to the phosphor layer side in the axial direction by the heat conduction from the mask frame 12, the elastic part 17 extends to the electron gun side, during the operation of the color picture tube. Consequently, even though a shadow mask 11 is composed of a metal of a small thermal expansion coefficient, and it is not displaced in the X, Y and Z axis directions by the thermal expansion, the interval between the shadow mask 11 and the phosphor layer is kept almost same as before the operation. The mislanding amount is never increased even in a long time of continued heating, consequently.

That is, a concentration of the dust is sensed by a dust densitometer A arranged at  an outlet flue of EP4 and then a signal of concentration is fed to the adjustor meter B via line  (a). In the adjustor meter B, a predetermined value of EP loading condition (for example, a  voltage) is produced at a power pack C through a line (b) in response to a differential value between the fed signal of concentration and the predetermined dust concentration value.
