Title: Microsyringe
Inventor: ITO RYUJI
IPC: G01N30/18
Filed: 1996-07-30
Abstract: PROBLEM TO BE SOLVED: To enable a microsyringe to sterilize with high temperature and high pressure by fixing a cylinder body, head part or the like with adhesives having heat resisting property. SOLUTION: A syringe body 10 is formed cylindrically, and a scale 18 is engraved on the outer peripheral surface. A plunger 12 is slid in the syringe body 10 so that a fixed amount of sample can be sucked or exhausted. A head part 16 is fixed to the syringe body 10 by adhesives having the heat resisting property and similarly a flange 15 is fixed to the syringe body 10 by the adhesives having the heat resisting property. Some adhesives having the heat resisting property may contain modified epoxy resin having main components of an epoxy resin or imide resin for example. Since the head part 16 or the like is thus fixed by the adhesives having the heat restating property, the adhesives are not degraded even by sterilization with a sterilizing device like an autoclave having high temperature and high pressure.

Title: Method for deciding state of processing solution in processor and printer processor
Inventor: MOGI FUMIO
IPC: G03D3/00
Filed: 1996-07-30
Abstract: PROBLEM TO BE SOLVED: To provide a method for deciding the state of processing solution in a processor and a printer processor capable of easily and accurately controlling the state of the processing solution considering the fluctuation of the characteristic of photosensitive material of every kind. SOLUTION: After performing light source correction and paper characteristic correction (102 and 104), a printing condition is maintained (106). Since a factor other than the fluctuation component of the state of the processing solution is hardly included in updated processing solution balance, the processing solution balance is set as an object and compared with the reference processing solution balance updated immediately after the solution is adjusted (108), compared with the processing solution balance of the previous time (110) and compared with the mean value of the processing solution balance of preceding ten times (112). In the case a difference found in any comparison is out of a reference range, a warning is displayed by deciding that the state of the processing solution is abnormal (118).  Thus, a user recognizes the deteriorating tendency of the state of the processing solution and quickly takes measures to perform const. (control strip) processing so as to confirm it. Even though such processing is not performed until the warning is displayed, the user confirms that the state of the processing solution is excellent.
