Title: Method for detecting reproducing signal in optical pickup
Inventor: ONAYAMA SHIYUUICHI
IPC: G11B7/135
Filed: 1988-09-16
Abstract: PURPOSE:To prevent the bad influence to the reproducing signal of a signal for detecting a tracking error by obtaining a reproducing signal due to a photodetector with the special operation in an optical pickup to provide a hologram grating having a diffraction grating on one side surface and a hologram surface on other side. CONSTITUTION:A reproducing signal R.F due to a photodetector is obtained by the operation of a next expression. In the expression R.F=A+B+C+D-K(E +F), A to F represents the light receiving output of respective segments of the photodetector and K represents a constant determined by the diffraction efficiency of the diffraction grating surface of a hologram grating. Namely, since the light quantity of a + or - primary light when the return light for detecting a tracking error transmits the diffraction grating surface again is determined by the diffraction efficiency of the diffraction grating surface, the light quantity can be known beforehand. Consequently, by setting a constant K in the expression to a suitable value determined by the diffraction efficiency of the diffraction grating surface, the sneaking part of a signal for detecting the tracking error to enter the reproducing signal can be cancelled and the bad influence to the reproducing signal of the signal for detecting the tracking error can be removed.

Title: Support adjuster for metal plate polishing brush roll
Inventor: HOTANI SETSUO
IPC: C23F3/00
Filed: 1982-12-28
Abstract: PURPOSE:To support a brush through a chock reliably by arranging an air-cylinder at the side of chock for supporting the shaft of brush roll then pressing/ releasing the chock through reciprocation of piston in said cylinder. CONSTITUTION:Upon pressure insertion of air through a pressure-insertion hole 5 of an air-cylinder 4 into a chamber (A) at the right of a piston 7, the piston 7 and a sliding member 11 will move to the left and its head 12 will press strongly against a chock 3. Since the chock 3 for supporting the core shaft 2 of brush roll 1 is supported reliably, the brush roll 1 is prevented from vibration during rotation. Whie when the brush roll 1 has abrased to provide insufficient contact against a plate to be worked, chambers A, B at both sides of piston 7 are opened. Consequently the piston 7 is moved by a spring 8 to the left to bring such state where the chock 3 is supported lightly by the head 12 of sliding member 11 to provide sufficient contact.
