Title: Rolling roll
Inventor: SASAKI YOSHIO
IPC: B21B27/00
Filed: 1992-05-22
Abstract: PURPOSE:To give excellent wear resistance to a rolling roll made up of a ceramic sintered body by grinding the rolling surface of a roll, then, restraining an amount of polishing work below a specified value and holding a residual compression stress beyond a specified value. CONSTITUTION:When the rolling roll made up of ceramic sintered body is ground to a prescribed dimension after it is sintered, residual stress is left on the surface of the roll. Then, when an amount of polishing work to finish the surface accuracy is restrained at >=20m, this compression stress can be left at >=100MPa. When the residual compression stress of the surface exceeds 100MPa, preferably exceeds 150MPa, excellent wear resistance is displayed, consequently, the life of the roll is sufficiently prolonged.

Title: Servo system for rotational recording medium
Inventor: WACHI SHIGEAKI
IPC: G05D3/12
Filed: 1986-07-02
Abstract: PURPOSE:To compress the constant deviation of eccentric components to a small value by providing a servo system loop for a rotational recording medium with an analog compensation circuit that the phase delay amount of touring loop frequency characteristics including an actuator associates almost with the frequency of an eccentric basic wave. CONSTITUTION:If the eccentric amount of a disk is aimed at in an feedback control circuit, a control target value xreff(t) is the function of a rotational frequency L. If the output of a propagation element G(s) is y(t), an error signal showing the constant variance equals xreff(t)-G(s)E(t). If the propagation element G(s) includes the model of the xreff(t), E(t) can be made into '0'. The xreff(t) denotes the eccentric amount of the disk and becomes the function of the rotational frequency L. The Laplace transformation of the target value xreff after one rotation can be shown by L[(xreff(t-L)]e<->LS.L[xreff(t)]. If the propagation element G(s) becomes the propagation function K.e<->LS of a delay circuit for delaying the phase of a signal by the frequency L, the constant variance can be made into '0'.

Filed: 1987-06-22
Abstract: PURPOSE: To stabilize a discharge starting voltage by making one-sided ends of paired flat plate electrodes of different heights face each other and juxtaposing a needlelike electrode on the higher electrode and disposing one end of the needlelike electrode to face that of the lower electrode nearly in parallel with each other.

A needlelike electrode 3 is juxtaposed on the higher electrode 2 and its one end 3a is protruded to the side of the lower electrode 1 and to face the lower electrode 1 nearly in parallel with a gap G in between. Since discharge is generated at a tip part of the one end 3a of the needlelike electrode 3 disposed nearly in parallel to the lower electrode 1, a discharge starting voltage can be kept constant without the discharge gap G being varied even if this discharge allows abrasion of the tip part of the needle to proceed a little.
