摘要:
A method for manufacturing a magnetic paint by mixing a resin composition powder as a dispersing binder for a magnetic powder with the magnetic powder, or together with a filler, and grinding the mixture under a high shear stress is disclosed. A magnetic recording medium such as a magnetic disk, etc., prepared by using the magnetic paint, can have a magnetic coating film having a substantially uniform film thickness of not more than 0.9 .mu.m and a surface roughness of not more than 0.05 .mu.m Ra before surface finishing.

A coating type, magnetic disk is produced by applying a magnetic paint containing magnetic powders in a dispersed state to a non-magnetic substrate, thereby forming a magnetic recording film thereon, and applying surface waves to the magnetic recording film in an undried state. By applying the surface waves to the magnetic recording film, dispersibility and orientation of the magnetic powders are improved and a longitudinally oriented, coating type magnetic disk with distinguished electromagnetic properties, such as a high S/N ratio, etc. can be obtained.

A method for magnetic orientation of a magnetic recording medium using Meissner effect of a superconductor and a system therefor and a magnetic recording medium produced thereby. The magnetic particles of plate hexagonal barium ferrite in the magnetic coating are allowed to orient in the longitudinal direction thereof so that a magnetic recording medium having a magnetic orientation in such direction with the magnetic particles can be obtained.

Even in the case of an information processing apparatus different from a computer usually used by a user, the same kana-kanji conversion candidates as the computer are acquired without unifying Japanese-language converting programs and unifying usage environments. The computer comprises a kana-kanji converting portion that receives a character string from an information processing apparatus through a network to return conversion candidates. The apparatus displays the conversion candidates.

A hybrid magnetic bubble memory device comprising soft magnetic material propagation tracks and ion-implanted propagation tracks. In the soft magnetic material propagation track region, a layer made of a heat-resistant polymer was provided as an interlaminar insulating layer between a conductor and a pattern of a soft magnetic material. An insulator film made of a heat-resistant polymer was provided on the pattern made of a soft magnetic material. A passivation film made of an inorganic material was provided on the ion-implanted propagation tracks and the insulator film made of a heat-resistant polymer.

An engine controller controls a plurality of devices in an image forming engine. The engine controller includes a communication interface to perform data communication with the main body controller, and a storage section for storing information. The storage section stores a character string-bit order lookup table, in which the order of arranged data for part of or all of a plurality of bit information items regarding a plurality of devices is associated with a plurality of character strings identifying the bit information items. A character string obtaining section sends out data with the character strings arranged in accordance with the arranged order, via a communication interface to the main body controller.

The present inventors provides polyol-containing resin compositions for coatings which can give cured coating films having high hardness and at the same time high solid compositions to meet the recent resources saving and/or environmental protection requirements, and curable coating compositions having high reactivity at curing, giving the coating film with good appearance and the coatings with prolonged pot life. The invention is directed to a resin composition for coatings comprising a polyol (A1) or (A2), a polyether polyol (B) and a solvent (C), wherein the polyol (A1) comprises a hydroxyl-containing polymerizable unsaturated monomer and a ring structure-containing polymerizable unsaturated monomer as essential components and the polyol (A2) comprises a hydroxyl-containing polymerizable unsaturated monomer and a linear branched structure-containing polymerizable unsaturated monomer as essential components.
