摘要： PURPOSE:To prevent completely a driving wheel from slipping by making a pair of driving wheels disposed on both right and left sides of the center of a vehicle body where an appropriate number of auxiliary wheels are provided on both ends of the front and the rear come into contact with a road surface with approximately uniform force, regardless of upper and lower strokes. CONSTITUTION:A vehicle is provided with a pair of driving wheels 1 on both right and left sides of the center of a vehicle body 4, and also an appropriate number of auxiliary wheels at both ends of the front and the rear of the vehicle body 4, whereas respective driving wheels 1 are constituted so that they may move up and down vertically with prescribed force in relation to the vehicle body 4 and they may come into contact with a road surface by approximate uniform force, regardless of the vertical strokes. For example, a pair of guide shafts 3 protruding from the driving device 2 of the driving wheel 1 are supported through a linear bearing 5 fixed on the vehicle body 4 so that they may operate up and down. One end of a rope 7, whose other end is fixed on an arm 6 which connects the edge parts of respective guide shafts 3, to each other is wound around a pulley 8 which is pivotally supported to the vehicle body 4, and is connected to a tension bar 9 supported by a tension spring 11.

摘要： PROBLEM TO BE SOLVED: To inexpensively and easily detect a non-combustible cylinder of an internal combustion engine. SOLUTION: An acceleration sensor 102 outputting a vibration waveform signal corresponding to the intensity of vibration is mounted on the internal combustion engine. The vibration waveform signal output from the acceleration sensor 102 is transmitted to a personal computer 201 through a moving packet communication network from a personal computer 105. The personal computer 201 produced the vibration waveform on the basis of the received data, divides the same corresponding to the explosion timing of each cylinder, and calculates a RMS value of the divided vibration waveform. The RMS value is compared with a reference value stored in advance to detect the non-combustible cylinder.

摘要： PROBLEM TO BE SOLVED: To improve work efficiency by safely and easily providing a guard curtain around the extensible endless belt of a conveyor device. SOLUTION: Strip type curtains 15A to 15D pulled out from a roll core 32 mounted on a roll support member 43 are engaged with a guide pin 41 via the side connection holes 17 thereof, and wound around each guide drum 40. Thereafter, each guide drum 40 is synchronously rotated on the operation of each rotary motor 42, and the curtains 15A to 15D are thereby delivered along an endless belt. Once the strip type curtains 15A to 15D are delivered from each guide drum 40, a joint wire connection part is connected to the curtains 15A to 15D and, then, the side connection holes 17 adjacent to each other are connected through a connection belt 20, thereby forming a cylindrical body 40 of the prescribed length. The feed of the strip type curtains 15A to 15D and the connection of the side connection holes 17 are repeated and the cylindrical body 45 is extended downward, thereby forming a guard curtain 15. For overhauling the curtain 15, each guide drum 40 is reversed, with the side connection holes 17 released from a connection state, and the strip type curtains 15A to 15D are wound around the roll core 32.

摘要： PURPOSE:To aim at prevention of contamination, improvement in operational safety, omission of oil conveyance by an operator and expedition of work through the automation of engine oil replacement. CONSTITUTION:An oil hose 3A is connected to the already attached oil hose 3 of an oil pan stored with drain oil via a quick coupler 4 and, after an operating panel is set to the whole cycle, a start switch is operated. If so, drain oil is automatically fed, under pressure, to plural drain oil drum cans 11, 11A from the oil pan 2 by way of an oil pump 7 and, after oil draining is over, fresh oil is automatically fed in order to the oil pan 2 from plural oil feeding drum cans 15, 15A by way of the oil pump 7. Subsequently, a controller at hand is operated, replenishing oil to the oil pan 2 stored with fewer oil than the reference quantity, thereby restoring it to the original quantity. An engine oil replacement is almost automatically performed, and since there is almost no work for an operator, prevention of contamination, improvement in operational safety, amission of oil conveyance by the operator and expedition of work are all promotable in this way.
