摘要： A micropump particularly suited for use in the fields of medicine and analysis includes a thin membrane plate sandwiched between a surface plate and a glass-made substrate. The intermediate membrane has an inlet valve and an outlet valve and the glass substrate has an inlet port and an outlet port, respectively connected to the corresponding valves. Between the valves formed in the thin membrane plate by means of etching, there is a diaphragm on which there is a piezoelectric element for detecting behavior of the diaphragm. Another micropump has an upper thin membrane plate member and a lower member. The upper member has the inlet valve and the lower member has the outlet valve. An intermediate glass substrate is inserted between the upper and the lower thin membrane plate member.

摘要： A watchdog timer capable of detecting clock signals when the opening frequency of a frequency source drifts lower or higher than a normal desired operating range, increasing circuit safety and reliability. The timer uses first and second clock oscillation circuits to generate first and second signals of frequencies f.sub.1 and f.sub.2 which are then divided by 1/N.sub.1 and 1/N.sub.2 in first and second frequency dividers, respectively. Third and fourth frequency dividers are used to divide the second frequency signal f.sub.2 by 1/N.sub.3 and 1/N.sub.4, respectively. A scale of N.sub.5 counter is connected to receive the f.sub.1 /N.sub.1 frequency signal as a clock input and the f.sub.2 /N.sub.3 frequency signal as a reset input, and provides an output signal at a frequency of (f.sub.1 /N.sub.1)/N.sub.5 which is less than f.sub.2 /N.sub.3 when the clock circuits are operating under normal conditions. A scale of N.sub.6 counter is connected to receive the f.sub.2 /N.sub.4 frequency signal as a clock input and the f.sub.1 /N.sub.2 frequency signal as a reset input, and provides an output signal at a frequency of (f.sub.2 /N.sub.4)/N.sub.6 which is less than f.sub.1 /N.sub.2 under normal conditions. A discrimination circuit is connected to monitor the outputs of the scale of N.sub.5 and N.sub.6 counters to determine the presence of a fault by detecting when either output no longer meets the associated relationship.

摘要： A humidity sensing apparatus which includes a humidity sensor which detects humidity as a function of impedance is provided. A reference resistor has a predetermined resistance value. A charge switching circuit selectively couples one of the reference resistor or the humidity sensor in series with a reference capacitor which has a predetermined capacitance. A voltage judging circuit determines whether the terminal voltage of the reference capacitor is high or low. A charge/discharge switch selectively charges and discharges the reference capacitor in accordance with the output of the voltage judging circuit. A sensor direction switching circuit inverts the direction of current flowing through the humidity sensor during charging of the reference capacitor. An oscillation frequency counter counts the number of charge/discharge cycles which are repeated during a predetermined time period. A humidity sensor resistance value calculating circuit calculates the resistance value of the humidity sensor in accordance with the number of repeated charge/discharge cycles when the reference capacitor is coupled to the reference resistor for charging and the number of repeated charge/discharge cycles when the reference capacitor is coupled to the humidity sensor during charging. A humidity determining circuit determines the humidity from the resistance value of the humidity sensor calculated by the humidity sensor resistance value calculating circuit.
