Title: Binder for magnetic recording medium
Inventor: NAKACHI TAKESHI
IPC: C09D127/00
Filed: 1987-12-15
Abstract: PURPOSE:To obtain excellent wear resistance by using a vinyl chloride copolymer having a hydroxyl group-contg. vinyl monomer and a vinyl monomer constituted by bonding a bulky cyclic group indirectly to a vinyl group as a constituting unit as the essential component of the title binder. CONSTITUTION:The vinyl chloride in the vinyl chloride copolymer imparts adequate hardness and flexibility together with the other constituting units to a magnetic layer. The wear resistance is too low if the ratio thereof is excessively low and the solubility is low if the ratio is excessively high; the more preferable ratio is 60-95wt.%. The amt. of the hydroxyl group-contg. vinyl monomer to be used results in the degraded solubility if said amt. is too large and results in the degraded dispersibility of magnetic layer if said amt. is too small; said monomer is preferably incorporated at 8-20wt.% in the polymer. The vinyl monomer which is formed by bonding the bulky cyclic group indirectly to the vinyl group and is used as the constituting unit of the vinyl chloride copolymer refers to the vinyl monomer formed by bonding the bulky cyclic group to the carbon atom constituting the 'vinyl group' and acrylic acid or methacrylic acid is preferably used. An isocyanate compd. such as tolylene diisocyanate is used at 0.3-30wt.% if there is a need for particularly enhancing the wear resistance and heat resistance of the magnetic layer.

Abstract: PROBLEM TO BE SOLVED: To increase opportunities for using energy effectively in vehicle energy supply control equipment which can convert kinetic energy in a moving vehicle into other energy and use it. SOLUTION: In the case of braking, a motor 30 connected with wheels 14 is made to act as a generator by the control of a control circuit 32. Electric energy obtained in this way is charged in a battery 21. The charge becomes a load, and rotation of the motor 30 is restrained so that rotation of the wheels 14 is restrained. When electric energy is supplied directly to a hydraulic braking device 24 and consumed, it becomes a load, and rotation of the wheels 14 is restrained.
