Title: Stirring member
Inventor: KATAOKA NAOKI
IPC: G03G15/08
Filed: 1997-02-03
Abstract: PROBLEM TO BE SOLVED: To provide a stirring member capable of stirring fine particles with low torque. SOLUTION: The stirring member 16 is constituted of a rotary shaft 24 and a rotating member 26 whose one end 28 is fixed to the rotary shaft and whose other end 32 is turnably attached to the rotary shaft. The other end 28 of the member 26 rotates with respect to the shaft 24 as the resistance of the fine particles to the member 26 becomes large. However, since one end of the member 26 is fixed to the shaft 24, the member 26 rotates with the shaft 24. Consequently, the stirring performance of the fine particles is not influenced thereby. When the fluidity of the member to be stirred becomes good, the other end of the rotating member is returned to an original position.

Abstract: PROBLEM TO BE SOLVED: To reduce the temperature difference between the actual temperature of a sample and a setting value by providing a temperature control mechanism at a cell cap that is fitted to a sample container, and make excellent heat transfer from the cell cap to the sample container and further to a sample solution. SOLUTION: A Peltier element 21 for heating or cooling is buried into a cell cap 2 that is engaged to a sample container 1. In the case of heating, heat generated in a peltier element 31 is transferred to the entire body of a metal cell holder 3 and further is transferred to a sample solution 1 via the bottom part and the side wall of the sample container 1, but the heat transfer is not always satisfactory. On the other hand, heat generated by the Peltier element 21 of the cell cap 2 is transferred to the side wall of the sample container 1 in close contact to a cap through the material of the cap and is transferred to the sample solution 11. The same is applied to the case of cooling, when it is considered that the generated heat is a cold heat.  A temperature control mechanism is incorporated into the cell cap 2, thus securing excellent heat transfer and accurately controlling temperature.
