Filed: 1987-08-21
Abstract: PURPOSE:To make the reproducibility of acceleration excellent by a method wherein an acceleration input signal is operated directly to control the acceleration of a vibration table while a signal component of the acceleration input signal not containing a frequency spectrum is operated to control the central position of the vibration table. CONSTITUTION:A displacement control mechanism controls a servo valve 6 of a an actuator by means of outputs of a displacement amplifier 10 and a table position setting unit 11, so as to maintain a vibration table in a position corresponding to an output voltage of the setting unit 11. On the other side, an acceleration control mechanism controls the servo valve 6 by means of an acceleration input signal and an output of an acceleration amplifier 13, so as to give the vibration table the acceleration corresponding to the acceleration input signal. Moreover, LPF 15 and HPF 18 are provided for the displacement control mechanism and the acceleration control mechanism respectively, and thereby a cutoff frequency is set so that the two control systems may not interfere with each other. By this constitution, the acceleration input signal is operated directly to control the acceleration and the acceleration input signal is reproduced with fidelity, while a signal of the displacement control system does not affect the spectrum of the acceleration input signal.

IPC: H01J23/05
Filed: 1983-11-09
Abstract: PURPOSE:To improve vibration resistance without sacrifice of insulation performance by constructing such that the projected portion of insulation spacer will engage with the engaging section of lower end shield at the outside of through- hole of lower end shield. CONSTITUTION:An insulation spacer 19 has a projected portion 19d at the outside of the section corresponding with a through-hole 13a of lower end shield 13. An engaging section 13c made of a hole to be engaged with said projected portion 19d is made in the lower shield 13. Since said projected portion 19d will engage with the engaging section 13c of lower end shield 13 for rhe vibration in all directions, strength of filament will increase. While since the insulation spacer 19 is not inserted into the through-hole 13a of lower end shield 13, the amount of metal to be adhered to said spacer 19 will decrease considerably resulting in improvement of reliability.

Title: System for controlling double failure prevention of disk array system
Inventor: MORIMOTO SETSUO
IPC: G06F3/06
Filed: 1998-07-24
Abstract: PROBLEM TO BE SOLVED: To normally interpolate data by correcting the data of a defective disk by using the data of another disk and the first parity when any failure is generated in one part of disks, and correcting an error from a part other than the error when any error is generated in the data and a second parity. SOLUTION: At the time of initializing an array disk(A/D) 2, an array controller(A/C) 1 prepares and initializes vertical parities in a block in addition to parities among each disk 20-23. The vertical parities are preserved in the A/C1 and each disk 20-23. When a write command is issued from a CPU 3 to the A/C1, the A/C1 reads data before update from an A/D2 at first. Then, the parities among each disk 20-23 are calculated, and the vertical parities are prepared from a difference between the data read from each disk at first and data to be written, and the data and the parities are written in the A/D2. Thus, the double failure of the array system can be reduced to the minimum.

Filed: 1985-09-21
Abstract: PURPOSE:To obtain pictures with extremely high contrast by detecting the peak value of a picture signal to obtain a binary coded slice level from the difference between said peak value and a reference level and therefore binary- coding accurately the picture signal. CONSTITUTION:An output picture signal of an image pickup camera 2 is shown as a signal 3a on a print surface and a signal 4a on a slip surface respectively. The signal 3a is dark compared with the signal 4a. If the signal 4a has a big difference between a reference level VREF and the peak value VP (owing to soil or color on the slip surface), the binary coded slice level VS is obtained from (VREF-VP). Therefore, the level VS is corrected and equal to the mean value between both signals 3a and 4a. In the same way, the level VS is equal to the mean value between the signals 3a and 4a even in case the difference between the level VREF and the value VP is small since the level VS is obtained from (VREF-VP).
