Filed: 1977-11-29
Abstract: PURPOSE: To improve the S/N ratio of a signal output circuit by containing a photoelectric face 1, detection resistance and buffer amplifier within the same casing in an ultraviolet ray ionization type SF 6  gas detector.  
     CONSTITUTION: When the photo electrons emitted from a photoelectric face 1 by ultraviolet ray radiation deposite on O 2 , SF 6  gas in a casing 4, these are ionized. Negative ions 6 move toward an acceleration electrode 2 to which a voltage is applied from an acceleration power source 5 between shield electrode 3, while being accelerated with said electrode 2. Hence, the minute signal generated by the  movement of the ions 6, i.e., displacement current, is flowed in a detection resistance 7 and is thereby converted to a voltage signal. This voltage signal is inputted  to a buffer amplifier 8 and is thereby amplified. Although the input impedance of  the amplifier 8 is high, it is converted to a low impedance by the amplifier 8 and  the signal having been reduced of the effect of the distribution capacity of lead-out wires is sent out to an amplifier 10 which has output terminal 11 and is provided  on the outside.

Title: Rack carrying device
Inventor: WATABE MASAAKI
IPC: G01N35/04
Filed: 1997-06-02
Abstract: PROBLEM TO BE SOLVED: To discriminate dislocation of a rack effectively utilizing existing constitution by providing a rack carrying mechanism holding sample vessels, and a discriminating means for dislocation of the rack during carrying utilizing read-out of rack identification labels. SOLUTION: Trays 14, 18 are carried, the contents of identification labels are recognized by readout control parts to be stored, and dislocation discriminators function so as to obtain correcting values. Because dispensation begins after completing initial readout and the first dispensing operation is performed, a fixed rack is positioned against dispensing nozzles 28, 30. Namely the trays 14, 18 are carried by a fixed quantity, the contents of the labels having vessels to be objects of dispensation are recognized anew, and the suitability of the contents are discriminated. Dislocation is discriminated by a dislocation discriminator based on the label readout signal. Consequently because recognizing anew the label and discrimination of dislocation of the rack are executed prior to dispensation, unsuitable dispensation is prevented from generating. In this way, dislocation of the rack can be exactly discriminated effectively utilizing existing constitution during rack carrying.
