Title: Device and method for switching clock
Inventor: ENDO HIROSHI
IPC: H04L7/00
Filed: 2000-05-18
Abstract: PROBLEM TO BE SOLVED: To prevent the variation of an output phase in switching an input clock by always matching the phases of plural input clocks. SOLUTION: The plural input clocks CLK0a and CLK1a whose frequencies and phases are different are frequency-divided respectively by frequency dividing circuits 11 and 12, and a clock selection circuit 14 selects one of the frequency- divided outputs with a clock selection signal 19. With respect to the other frequency-divided outputs, which are not selected, a reset pulse generation distributing part 13 outputs a reset pulse generated based on the output clock of the circuit 14. Thus, the phases of the plural input clocks are matched constantly and the variation of the output phase in switching the input clock can be suppressed.

Title: Detection of sample for starting timing of electrochemical measurement
Inventor: OHARA TIMOTHY J
IPC: G01N33/487
Filed: 2000-06-15
Abstract: PROBLEM TO BE SOLVED: To calculate the concn. of an object to be detected by monitoring the potential difference between electrodes across which a constant current source is connected and determining a sample detecting time at a time when the potential difference becomes a threshold value or less and applying constant voltage to sample to measure electrical response of a constant time. SOLUTION: A weak constant current source is connected across the electrodes of a strip for electrochemical diagnosis to monitor the potential difference between the electrodes. A dry gap is provided between the electrodes and a negligible current flows across the electrodes at an initial stage. When a sample is applied to the strip to fill the gap, measuring voltage drops suddenly and a test is started at this point of time. When the application of the sample is recognized, an apparatus is changed over from a constant current mode to a constant voltage mode and, in the constant voltage mode, a current or charge is measured as a function of time and the calculation of the concn. of an object to be detected becomes possible. By this method, the error introduced into signal responce by a timing start circuit is minimized and a detection restricting value can be lowered.
