Title: Feed control method for pickup of disc player
Inventor: NEGISHI TADASHI
IPC: G11B21/08
Filed: 1994-09-16
Abstract: PURPOSE: To detect the load being applied to a feed motor accurately in relation to the load for feeding a pickup. CONSTITUTION: A pickup PU4 located at a predetermined position is shifted from the inner peripheral side to a predetermined position on the outer peripheral side through the rotary motion of a motor 2 caused by a drive circuit 12 and the driving current is measured by means of a measuring circuit 13. The load of a PU feeding mechanism is detected based on the magnitude of current at that time and the shifted position of the PU4 is detected based on the number of pulse signals generated from a pulse signal generation circuit 15. Consequently, the load of the PU feed mechanism can be detected in relation to the shifted position of the PU4. Since the motor 2 is rotary driven with a voltage suitable to the load of the PU4 at a shifted position, the PU4 can be set with a desired feeding amount at the time of search operation and thereby the searching speed can be increased.  In other words, the load of the PU feed mechanism is detected by measuring the driving current of a PU feed motor thus detecting the load thereof accurately.

Title: Production of copolymer
Inventor: NAMITA YASUO
IPC: C08G81/00
Filed: 1983-11-28
Abstract: PURPOSE:To produce a copolymer of a desired composition ratio in good efficiency without decreasing the MW of an olefin polymer, by treating a styrene polymer with ozone and melt-kneading the treated styrene polymer with the olefin polymer. CONSTITUTION:A styrene polymer (e.g., PS, styrene/acrylonitrile resin, or acrylonitrile/butadiene/styrene resin) is pretreated with ozone. The treated polymer is melt-kneaded with an olefin polymer (e.g., PE, PP, or ethylene/propylene copolymer). These polymers rapidly react with each other to form a graft copolymer in which the styrene polymer is grafted onto the olefin polymer or vice versa. Bcause it is not necessary to subject the olefin polymer to irradiation, treatment with ozone or a like treatment, a decrease in the MW of the olefin polymer, otherwise caused by decomposition of the like, does not occur and it is possible to obtain a copolymer excellent in various properties.
