Title: Tracking controller
Inventor: AKIYAMA TORU
IPC: G11B7/085
Filed: 1985-04-15
Abstract: PURPOSE:To lock a tracking servo loop accurately and quickly by closing this servo loop when an on-track signal showing that a pickup is set on a track is detected out of the output of a waveform shaping circuit. CONSTITUTION:An averaging signal is supplied to a clamping circuit 31 from a spot 1 via an amplifier 4. The circuit 31 is provided with a coupling capacitor 32, a buffer amplifier 33 having gain '1', for example, a resistance 34 and a switch 35. An inverter 36 control the ON/OFF of the switch 35. A loop control signal of a high level is supplied to the input at the other side of an AND gate 7. Thus an on-track signal passes through the gate 7 and closes a loop switch 8. A tracking servo loop is locked when the relative speed between a pickup and a track is reduced sufficiently. The on-track signal can always be detected immediately after the tracking servo loop is closed by clamping the averaging signal is clamped immediately before said servo loop is closed.

Filed: 1993-03-15
Abstract: PURPOSE:To obtain coagulates of a polymer having a low glass transition temp., excellent in optical properties and handleability by producing a latex of the polymer by emulsion polymerization, completely freezing the latex, and then thawing and dehydrating it. CONSTITUTION:A polymer latex in which the outermost layer of each polymer particle has a glass transition temp. of -20 to 60 deg.C is obtained by emulsion polymerization. This latex is completely frozen at -5 deg.C or lower to cool the latex to the eutectic point or lower. The frozen latex is thawed and dehydrated to obtain the polymer as coagulates. This method is applicable to a latex of a graft polymer produced by grafting with rubber particles.
