摘要： PURPOSE: To make the life of a nonvolatile memory long, by updating memory places at every specified running distance, writing the integrated running distance in the nonvolatile memory, and reading and displaying the value as required
CONSTITUTION: The number of pulse signals from a pulse generator 1 is counted by a counter 3. A program in an ROM5 is executed by an MPU4. A running distance and an integrated running distance are computed in correspondence with the counted number. The results are displayed on a digital display part 8. Addresses are sequentially updated at every 100-m running based on the instruction from the MPU4, and the integrated running distance is written in an integrated-running-data memory part in a nonvolatile memory 7. When a power source is turned ON again and automatic resetting is performed, the data is read and written into an RAM6. The data is used as the integrated running distance data.

摘要： PURPOSE:To detect liquid level stably over a wide range of temp., by making voltage applied to a sensor change in accordance with a change of temp. CONSTITUTION:Voltage VS is outputted through a constant-voltage circuit 2 from a power supply 1 and is applied to a series circuit of a coil 3a of a lead switch 3 and a thermister 4 for a liquid surface detection. The resistance of the thermister 4 becomes small as a temp. elevates and the collector-emitter voltage of a transistor TR1 is changed so that an output voltage increases. While, in compliance with an operation of a level sensor, when the thermister 4 in oil is exposed to the air, a heat dissipation constant becomes small and a resistance becomes small and electric current flowing in the coil 3a becomes large and a contact 3b of the switch 3 is turned on and an alarming lamp 5 is turned on a light. The voltage applied to the thermister 4 is increased as the atmospheric temperature comes down.

摘要： PURPOSE:To enable automatic correction for the output variance without change in the oscillating frequency, by controlling the output level detecting means of an ultrahigh frequency oscillator with the output control means provided in the path leading ultrahigh frequencies. CONSTITUTION:A gun oscillator 3 is oscillated from a DC power supply 4, the output passes through an isolator 5 and the waveguide mounting an output control diode 10 and reaches a reception section 11. A part of the output is detected with a monitor diode 7 mounted near the H-plane tube wall and the detected voltage corresponding to the output is obtained. The detected output of a diode 7 is compared with the reference voltage at a differential amplifier 9, the deviation is amplified and fed to the diode 10 and the output of oscillator can automatically be controlled so that the output of the diode 7 is constant. The isolator 5 suppresses the frequency change of the oscillator due to the change in the capacitor of the diode 10, the output variance only is controlled and a constant output can be obtained.

摘要： PURPOSE:To mask the noises in wheel speed pulses by forming a gate signal which is synchronized with a wheel speed signal whose waveform is shaped and passes only the normal pulses. CONSTITUTION:The output of a wheel speed sensor 201 is transformed into the wheel speed pulses by a transistor 237, and a specified phase is delayed by integrating circuits 215 and 233. The AND value F is obtained in an AND circuit 247 from the phase delayed pulses via a transistor 237 and the wheel speed pulses B. The wheel speed pulses B are fed to one shot circuits 241 and 243 and transformed into the pulses whose width is narrower than the length of the phase delay. The AND value is obtained from the output G and the AND value F and the wheel speed signal H is outputted. Since the phase delayed signal is used, the effects of the erroneous count and the like due to the noises and the like can be eliminated.
