Filed: 1989-09-29
Abstract: PURPOSE:To deal with an oil leakage trouble in accordance with a situation by a method wherein a fluctuation value obtained by comparing the respective detected values of the lowest oil level of the day and the lowest oil level predetermined days ago with each other and an oil level obtained by comparing the lowest oil level of the day and a lower limit alarm level with each other are used to calculate a degree of emergency and the calculated result is displayed. CONSTITUTION:A CPU 6 reads stored data of a memory device 9 and calculates a fluctuation value from the difference between the lowest oil level of the day and the lowest oil level the day before or the predetermined days ago. As there is a possibility of an oil leakage if the fluctuation value is positive, a degree of emergency which indicates when the oil level reaches a lower limit alarm level is calculated in accordance with the fluctuation value and an oil level obtained from the difference between the lowest oil level of the day and the lower limit alarm value. The calculated result is displayed on the alarm panel 12 of a monitoring station 2 with letters, symbols and the like. The displayed result is renewed every day. With this constitution, the degree of emergency can be informed and an oil leakage trouble can be dealt with flexibly.

IPC: G01S13/60
Filed: 1996-09-27
Abstract: PROBLEM TO BE SOLVED: To correct the effect of disturbance due to vertical vibration of vehicle body and reduce the error by vertically irradiating road surface with wave from a vehicle body, detecting vertical vibration of the vehicle body based on Dappler effect from the deviation of frequency of reflection wave and correcting the reception level of the reflection wave from a wave reflector. SOLUTION: A Doppler sensor 10 has an antenna 18 similarly provided in the lower part of vehicle body to antennas 15 and 16. The wave received with the antennas 15 and 16 is detected as high frequency signal and converted to intermediate frequency(IF) signal from the high frequency signal supplied with a local oscillator 19. A lane marker detector 20 compares signal level after converted from the wave detected with antennas 15 and 16 to the IF signal and measures and detects the position of the lane marker to the vehicle body 13. The measured value of position is corrected from the timing of vertical vibration of the vehicle detected with the Doppler sensor 10 and thus measurement accuracy is improved.

Abstract: PROBLEM TO BE SOLVED: To stably travel a belt for a short time at the time of a first use starting by fixing and mounting a belt driving device provided with a deviation control mechanism to a printer, etc. such that a deviation control roller is approximately parallel to the other roller and releasing the fixing when the belt driving device is operated. SOLUTION: A shaft end portion 3a is fixed between a side wall of a cut-in portion of support member 6 and a pinion 33 by attaching a fixing tool 60 such that a deviation control roller is positioned in approximately parallel to a driving roller and a tension roller. This is assembled to a printer as such and this fixing tool 60 is removed prior to firstly using the printer. At the time of first use, a time until a flat belt repeats a reciprocation deviation to a width direction to obtain a stable traveling is shortened as compared with the case where a deviation detection member attached to a movable shaft end portion 3a of the deviation control roller is positioned at a position deviated from an equilibrium position.  When the stable traveling is obtained, a deviation control of the flat belt is carried out from the position at the time of next use by engaging a rack with the pinion 33.

Filed: 1990-09-26
Abstract: PURPOSE:To improve self-cleaning work of spark plug, and prevent smoking and wetting damage of the spark plug, and ignite the dense air-fuel mixture securely for combustion by providing a current break type ignition means and a capacity discharge type ignition means. CONSTITUTION:A spark plug 50 is connected to an ignition device 52 electrically. This ignition device 52 consists of a current break type ignition means 53 and a capacity discharge type ignition means 54. At this stage, electric spark is thrown from the ignition means 53 to the spark plug 50 at a point near a compression top dead center to ignite the air-fuel mixture for combustion. When a piton is pushed down by the combustion explosion of the air-fuel mixture and an exhaust port starts to be opened, the electric spark is thrown from the ignition means 54 to the spark plug 50. Consequently, carbon adhered to an electrode of the spark plug 50 can be burned off for elimination. Besides, since the spark connection time of the ignition means 53 is long, chance of igniting the air-fuel mixture is increased.

Filed: 1987-10-12
Abstract: PURPOSE: To prevent a runaway of an arm and damage and the like in a workpiece by automatically measuring a pulse number of a pulse generating means arranged in a motor from just after the actuation of an origin limit switch installed to the robot arm until just before generation of zero-pulse of a servomotor, comparing the pulse number with a set value, and returning the arm to the origin position. CONSTITUTION: In detection of an origin position of a robot arm 10 by means of an origin limit switch 14, a zero-pulse generating means and a continuous pulse generating means 30 are arranged in a servomotor 22 driving the robot arm. From just after the actuation of the origin limit switch 14 until an appearance of the next zero-pulse Po , a number of pulses obtained from the continuous pulse generating means 30 is counted. Then, the counted pulse number is compared with a reference pulse number showing that the robot arm is in the accurate origin position, so that it is determined whether the robot arm 10 is in the accurate origin position or not. If the robot arm 10 is not placed in the accurate origin position, the robot arm 10 is returned to the origin position, and a runaway of the robot arm 10 can be prevented.
