Title: Method for measuring activity of alkaline phosphatase
Inventor: MATSUURA TSUNEAKI
IPC: C12Q1/42
Filed: 1984-05-01
Abstract: PURPOSE:To obtain an activity value which is an index useful for diagnosis of acute hepatitis, etc., by oxidatively coupling a liberated substance prepared by action of an alkaline phosphatase with disodium p-aminophenyl phosphate as a substrate, and measuring the formed blue dyestuff. CONSTITUTION:The activity of an alkaline phosphatase is measured. In the process, the alkaline phosphatase is hydrolyzed with disodium p-aminophenyl phosphate as a substrate, and the liberated p-aminophenol is oxidatively coupled with xylenol in the presence of sodium periodate to measure the absorbance of the resultant solution varying depending on the amount of the formed N-p- phenoxy-3,6-dimethyl-quinoneimine. Thus, the activity value is obtained by colorimetry using a standard solution. The exact measurement of the absorbance can be carried out without influence of hemolysis nor bilirubin, etc. since the N-p- phenoxy-3,6-dimethyl-qiuinoneimine assumes blue color.

Title: Film feed controller for camera
Inventor: ARAKI KUNIHIKO
IPC: G03B17/00
Filed: 1987-04-10
Abstract: PURPOSE:To surely expose as many photo frames as possible by counting the total number of perforations when a film is preliminarily wound up, obtaining the maximum number of photo-enabled frames, and driving the film to an exposure frame position based on the obtained result. CONSTITUTION:The output from a perforation detector 10 is inputted to a counter circuit 20. While the film is preliminarily wound up, the total of pulses outputted from the perforation detector 10 is counted. An arithmetic circuit 30 calculates the maximum number of photo-enabled frames that corresponds to the number of pulses outputted from the counter circuit 20, and supplies the result to a drive control circuit 40 which generates a control signal for deciding the setting position of a first frame, and another control signal for driving the film to an appropriate exposure frame position. The drive control circuit 40 drives and controls a driving circuit 50 including a film feed motor. The driving circuit 50 feeds and drives the film. Thus such a problem can be prevented that the part exposed in loading film overlaps an actually photographed frame.

IPC: D06F39/08
Filed: 1996-04-10
Abstract: PROBLEM TO BE SOLVED: To eliminate the necessity of rotating a drainage pump by interlocking with a dehydrating cover, and improve power saving and safety by arranging a water detecting means on the inlet side of the drainage pump communicated with a dehydrating tank and a washing tank through a waste pipe, and controlling the drainage pump by output of this water detecting means. SOLUTION: After a washing process is finished, when a drainage switching lug 14 is switched to 'drainage', a detecting part 25a of a drainage pump control part 25 sends a signal from a control part 25b by detecting water by a water detecting means 24, and a drainage pump 7 is rotated by closing a contact point 26a of a drainage pump switch 26, and a washing liquid in a washing tank 1b is drained. After drainage is finished, when the drainage switching lug 14 is returned to 'washing', a drainage cock is closed simultaneously when operation of the drainage pump 7 is stopped. In this case, even in the case where a user forgets to return the draingage switching lug 14 to 'washing', when drainage is finished, since the water detecting means 24 opens the contact point 26a of the drainage pump switch 26 by detecting the 'nonexistence' of water, operation of the drainage pump 7 is stopped.
