Abstract: A bush bearing (1) is a wrapped bush bearing which has a cylindrical inner peripheral surface (2) serving as a sliding surface as well as an outer peripheral surface (3), and whose abutting faces (4) are abutted against each other. The outer peripheral surface (3) includes a cylindrical surface (11); a tapered surface (13) interposed between the cylindrical surface (11) and one annular end face (12) in an axial direction X and formed by roll forming; a smooth circular arc surface (14) interposed between the tapered surface (13) and the cylindrical surface (11); and a smooth circular arc surface (15) interposed between the tapered surface (13) and the end face (12).

Abstract: A battery pack that reduces thickness and lightens weight as required for battery power sources of portable electronic equipment. A battery pack is constituted by accommodating a battery and battery protection device between a top case and bottom case forming a pack case. Since the battery is formed accommodated within an external casing wherein positive and negative electrode plates are formed by laminated sheet, reduced thickness and reduced weight of battery pack can be achieved. Also, since the face of bottom case opposite the battery is formed as a resiliently deformable face which is formed of small thickness, when expansion takes place such that the thickness of the battery as a whole increases, resiliently deformable face deforms maintaining a planar condition by resilient deformation, so that there is no possibility of an adverse effect on the equipment due to drum-shaped swelling being produced in battery pack, by such swelling.

Abstract: Disclosed is a light-sensitive lithographic printing plate which comprises an aluminum plate having a surface subjected to roughening treatment and then anodization treatment and colored by a solution containing a UV absorber so that at an absorption local maximum wavelength between 340 and 450 nm, reflection optical density DS is higher by 0.02 to 0.5 than that obtained when the surface is not colored, and a positive light-sensitive composition layer containing an o-quinonediazide compound and a clathrate compound provided by coating on the aluminum plate after coloration.

Abstract: An immobilized enzyme having an enzyme entrapped in gaps formed in a macromolecular gel matrix is produced by dispersing the enzyme in the form of a fine powder in an organic solvent having dissolved therein a polymerizable monomer, polymerizing the monomer thereby giving rise to a gel matrix, and displacing the organic solvent in the gel matrix with an aqueous solvent.

Abstract: An armature of double insulation construction for commutator motors of the wound-rotor type and a method of making the armature. An insulator insulating an iron core from a shaft and windings from the iron core also insulates a commutator from the shaft and unites the shaft, iron core and commutator into an integral rigid body. The armature can be fabricated with high precision by a simplified method.
