Title: Method for recovering dna
Inventor: OSHIHARA WATARU
IPC: G01N33/50
Filed: 1989-06-02
Abstract: PURPOSE:To rapidly and readily recover DNA dilutely present in a biological sample liquid by bringing the biological sample liquid containing the DNA into contact with glass powder and then concentrating the DNA on the glass powder. CONSTITUTION:A biological sample is mechanically or chemically treated with an enzyme to prepare a biological sample liquid containing DNA. A reagent (e.g. sodium iodide) capable of forming chaotropic ions is then preferably added so as to enhance action of adsorbing the DNA in the resultant DNA sample liquid on the glass surface. Glass powder (e.g. flint glass powder) is subsequently added and stirred to adsorb the DNA on the glass powder. The obtained glass powder adsorbing the DNA is then separated from the solution by a method for centrifugation, etc., and the DNA is recovered by a method for adding an aqueous solution in a low salt concentration, then eluting the adsorbed DNA, etc.

Title: Disconnecting switch
Inventor: NISHIZAWA TORU
IPC: H01H31/20
Filed: 1999-05-24
Abstract: PROBLEM TO BE SOLVED: To use a moving blade as an intermediate electrode to make consideration of insulating distance unnecessary and reduce an installation space by fixing the intermediate part in the length direction of the moving blade for connecting or separating a pair of terminals through an insulating member, and connecting a rotating shaft to a driving means so as to move together. SOLUTION: In the state that a moving blade 27 is almost parallel to a base 14, both ends of the moving blade 27 come in contact with terminals 18, 19 and a disconnecting switch 15 becomes a connecting state. When an insulating shaft 22 is turned at about 90 degrees with a driving means, the moving blade 27 becomes almost right angle to the base 14. At that time, since the moving blade 27 becomes double break in which the circuit of a terminal 18 is disconnected and the circuit of a terminal 19 is also disconnected, the moving blade 27 becomes a non-charging part. Therefore, consideration of insulating distance is made unnecessary, the opening distance of the moving blade 27 is made short. Consideration of the rotation of the moving blade 27 caused by gravity is made unnecessary, fixing attitude of the disconnecting switch is not restricted, and structure is made simple.

Title: Method for roughening surface of electrostatic charging roller
Inventor: SAKO SHUNKAI
IPC: G03G15/02
Filed: 1989-06-07
Abstract: PURPOSE:To stably obtain a copy image of high picture element while eliminating its ground staining by making abrasive materials abut on the electrostatic charging roller in >=2 directions which differ in angle to the generating line direction. CONSTITUTION:Feed rollers 13 and 13' and take-up rollers 15 and 15' are moved forth and back in the axial direction of the electrostatic charging roller to make the abrasive materials 12 and 12' pass pressure rollers 14 and 14' at specific positions and at specific angles to the generating line direction of the electrostatic charging roller. At such a time, the angles between the generating line direction of the electrostatic charging roller and the moving directions of the beltlike abrasive materials 12 and 12', i.e. the generating line direction of the electrostatic charging roller are made different from each other. Consequently, a uniform surface roughened state wherein the maximum roughness, mean roughness, and minimum roughness are all in specific ranges can be realized, and consequently the irregularity of electrostatic charging is almost eliminated. Consequently, ground staining due to an irregularity of electrostatic charging and the sticking of toner on the electrostatic charging roller is not caused and a stable image is obtained repeatedly.

The charges of the diodes 7-1, 7-4 which have many storage charge amount are fed to the shift registers 13-2, 13-4 having large transfer charge allowance, and the charge of the diodes 7-2, 7-3 which have less storage charge amount are fed to the shift registers having small transfer charge allowance.
