Title: Plasma treatment device
Inventor: WATANABE SEIICHI
IPC: H01L21/205
Filed: 1994-03-17
Abstract: PURPOSE:To provide a plasma treatment device capable of generating high density plasma and easily generating plasma at low pressure by installing a coil capable of applying a multipole magnetic field and high frequency voltage in the surrounding of a treatment chamber or the surrounding of a discharge chamber. CONSTITUTION:When high frequency voltage is supplied to a coil 3 installed in the surrounding of a treatment chamber 1, plasma loss on the wall surface of the treatment chamber 1 is reduced and higher density plasma is generated in the vicinity of the wall. By a multipole magnetic field 4 installed in the vicinity of the coil 3, plasma in a part continuing to the wall surface of the treatment chamber 1 is reduced, and plasma loss on the wall surface is reduced to increase the plasma density as a whole. Since the plasma loss on the wall surface is reduced and electrons to become the ignition source of plasma are restricted, plasma is easily generated even in a low pressure region. The multipole magnetic field 4 is formed by alternately arranging S poles and N poles of a permanent magnet, and the coil 3 is preferably a helical coil.

Filed: 1995-03-07
Abstract: PURPOSE: To quickly acquire a rough filter characteristic, to prevent production of noise sound, and to output a regular voice in a short time by transferring a coefficient corresponding to a tap area having many taps with a large coefficient of a digital filter at application of power from a memory to a buffer memory in advance. CONSTITUTION: Number of taps of a FIR filter is divided into an area A where many taps with a high coefficient are in existence and other area B, and a coefficient for the area A is transferred earlier and then a coefficient for the area B is transferred from a nonvolatile memory 4 under the control of a microcomputer 311 at application of power or at revision of the coefficient. That is, the microcomputer 311 transfers the coefficient in the area A to a coefficient buffer memory 305A and after the coefficients are all transferred, the coefficient of the area B is transferred to a buffer memory 305B. Since actual high coefficients are given to the area A, the filter with a rough characteristic is obtained early and the microcomputer 311 controls a sound volume adjustment device 310 at this point of time to release silencing and a sound is outputted early.

Title: Load sharing control circuit for long material transferring device
Inventor: ODA KOICHI
IPC: B65H20/02
Filed: 1992-03-05
Abstract: PURPOSE:To switch operation of a roll to speed control without any switch signal and/or a circuit switching device by a method wherein a slip suppression signal by means of which a deviation value between the speed command value of a roll under load sharing operation and a speed detection value is reduced to zero is added to a speed command value. CONSTITUTION:A speed command value inputted to a second control circuit 26 through a reference roll control delay setter 4 and the speed detected value of a second electric motor 22 outputted from a speed detector 23 are inputted to a slip suppression circuit 40. A control signal by means of which a deviation value between two input signals is reduced to zero is added to a speed command value by the slip suppression circuit 40. Thus, when a slip occurs between a long material 2 and a reference roll 11 or between the long material 2 and a helper roll 21, a deviation is produced between two input signals to the slip suppression circuit 40. In order to prevent production of the deviation, automatic transfer from load sharing control to speed control is effected to prevent the occurrence of any slip. Thereby, there is no need for a generating circuit for a switching signal and a circuit switching circuit and constitution of a circuit is simplified.

IPC: G05B19/02
Filed: 1989-02-27
Abstract: PURPOSE:To arbitrarily set the maximum value, the inclination, the inclination width, etc., of a target value by forming a signal train inputted to shift registers to a pulse shape. CONSTITUTION:The pulse period is preliminarily determined in accordance with a number (m) of shift registers and a pulse width is changed from one to (m) to extend or shorten an acceleration/deceleration time Ta. A pulse height H is increased or reduced to increase or reduce an acceleration alpha, and a steady speed V is determined by the pulse area (HXW). The shape of one pulse is determined based on the movement speed V, the acceleration alpha, and the acceleration/deceleration time in this manner, and a number N of pulses is so determined that an object can be moved for a length P by pulses. That is, a pulse signal train is inputted to the shift register array, and the total sum of stored values of respective registers is obtained at each time of shift to obtain the target value. Thus, the total sum (target value) of contents of shift registers can be quickly or slowly increased or reduced, and the inclination of increase/reduction is equalized regardless of difference of the steady value.
