    摘要： A variable power optical system composed of a first optical part (G1) for refraction, a second optical part (G2) for reflection or transmission, and a third optical part (G3) for refraction, with the first optical part being movable with respect to the second and third optical parts to change the focal length of the entire system, wherein the second optical part or the third optical part has a guide 4 which is in contact partly with the first optical part in such a way as to restrict its moving direction and the first optical part is movably held between the second optical part and the third optical part. This structure eliminates the necessity of separately forming the guide to move G1. The guide 4 is formed from a synthetic resin integrally with the stationary optical part (G3).

    摘要： A variable power optical system composed of a first optical part, a second optical part, and a third optical part, with the first optical part being movable with respect to the second and third optical parts to change the focal length of the entire system. The first optical part is movably held between the second optical part and the third optical part. The first optical part moves in the direction perpendicular to the optical axis over a distance between the position on the optical system of the entire system and the position of retraction from the optical axis of the entire system.

    摘要： A core bit includes a tube (2) having an opening end surface (21) in the axial direction and a plurality of tips (3) fixed to the opening end surface (21) of the tube (2). Each of the tips (3) includes an abrasive grain layer (31) that contains diamond abrasive grains and a binder for bonding the diamond abrasive grains to each other. The diamond abrasive grains contain not more than 0.03 weight % of inclusions. The inclusions contain iron and nickel as main components. The binder contains at least 0.1 weight % and not more than 2.0 weight % of graphite. The core bit has a short perforation time, i.e., a high cutting speed, excellent sharpness, excellent durability, and a long life. The core bit is suitable for boring a concrete structure.
