Title: Charged particle deflecting magnet
Inventor: WASA YASUHIRO
IPC: H01F7/02
Filed: 1991-05-10
Abstract: PURPOSE:To adjust magnet field intensity by installing a magnetic substance for magnetic bypass adjacently to a permanent magnet. CONSTITUTION:A magnetic substance for a bypass 7 is arranged in parallel with the magnetizing direction of a permanent magnet 3. It is possible to change partially bypassing quantities of the magnet flux flowing from the magnet 3 to yoke magnetic substances 4, 5 by changing an interval G between the magnetic substance 7 and the magnet 3. The quantity of magnetic flux flowing from the magnet 3 whose magnetic flux density is constant to the magnetic substances 4, 5 is made to change so that the magnetic field intensity in a magnetic field space 6 is changed. The interval G between the magnet 3 and the magnetic substance 7 is adjusted by moving, the magnetic substance 7 by connecting a gap adjuster 8 to a moving mechanism which uses oil pressure or water pressure. Since magnetic field instensity can be changed, while the uniformity of magnetic field distribution is kept in a deflecting magnet by means of a permanent magnet, it is possible to solve such problems as high expeuse equipment of deflecting magnets acting by means of electromagnet and a high level of the running cost.

Title: Single pole pulse generator
Inventor: IKUTA KAZUNARI
IPC: H02K31/00
Filed: 1990-04-23
Abstract: PURPOSE:To obtain an arbitrary waveform of output pulse current by employing a movable slip contact means and moving the slip contact means axially while controlling the moving speed. CONSTITUTION:When a current is fed from a capacitor 13, a second slip contact means 6 moves, with high speed, from one end 3b of a rolling body 3 toward the other end 3b thereof along an arrow A. When the second slip contact means 6 moves from one end 3b to the other end 3c due to arc discharge, it passes through a field shown by magnetic lines B of force and thereby current value shown on an ammeter 8 rises from zero, reaches a peak at a central position and returns to zero when the second slip contact means 6 arrives at the other end 3c. When discharge current supply from the capacitor 13 is further sustained, the second slip contact means 6 is pushed out from between the rotary body 3 and an electrode body 10 and thereby the arc discharge extinguishes temporarily, but a voltage induced at this instance actuates arc discharge to pull in the second slip contact means 6 again.

Title: Tracking error signal detector
Inventor: MIYAIRI NOBUO
IPC: G11B5/588
Filed: 1984-05-27
Abstract: PURPOSE:To prevent signal interference in a tracking error filter so as to detect tracking errors stably, by installing a gate circuit, filter initializing circuit, etc., which block input signals to the filter at the tracking error filter. CONSTITUTION:An appropriate section of filter constituting elements is forcedly short-circuited so that the residual voltage in a filter I 2 becomes zero by generating a clear pulse for an appropriate period by inputting the output of a comparator 8 in a timing generating circuit II21. The output of the timing generating circuit II21 is supplied to a filter initializing circuit 22 and the extracting filter I 2 is initialized. When the filter I 2 is initialized in such a way, ripples caused by interference in the filter do not occur when the next signal is inputted, and the output level voltage of the signal can be detected properly. Therefore, a filter which does not produce transient ripples while holding a sharp separating characteristic can be constituted easily.
