摘要： An optical pick-up device includes: a yoke plate having yokes formed at a front side where a magnetic body and a magnetic driving coil are positioned to drive an objective lens; a frame molded to the yoke plate in such a manner that a portion of the rear side of the yoke plate is inserted thereinto; and a PCB with at least two portions fixed to the frame, for applying a drive signal to the magnetic driving unit. Since the frame is press-fit to the yoke plate and the PCB with several portions coated with the adhesive is fixedly attached to the frame, it is not necessary to use an engaging member such as a screw, so that its assembly can be improved and the frame and the PCB can be prevented from being shaken.

摘要： A method for obtaining DNA from fish spermatogonia comprises (i) disrupting fish spermatogonium to obtain a milky-white colloid, (ii) adding an alkaline solution of pH 8 to pH 12, containing more than 1 mol of salts, such as monovalent salts, to the milky-white colloid, to separate DNA from protamines, and then (iii) adding ethanol solution to the resultant mixture, effecting a precipitation of DNA.
