Inventor: HONDA TAKESHI
IPC: G01M7/00
Filed: 1987-12-22
Abstract: PURPOSE:To perform test running at a highly accurate collision speed, by calculating the optimum acceleration curve by estimating the running resistance value of the whole of a system and the damped vibration phenomenon of a traction rope and operating an electromotor according to said curve. CONSTITUTION:The wt. of a vehicle to the tested is performed and acceleration is started on the basis of a preset rising curve and a predetermined current value. At this time, moving body passage detectors are provided at a point (tp1) wherein the sped of the vehicle C to be tested at the starting point and a current value are extremely low and at two points (tp2, tp3) in a relatively low speed region where a rising curve SL is finished and acceleration is performed on the basis of a constant current value and the speeds of a take-up drum at the point of time when the passage at the respective points is detected are set to V1-V3. In the take-up drum, the take-up length of a traction rope is measured. By this method, the take-up length of the traction rope during a period when the vehicle C runs between two points tp1, tp2 is measured. In general, when the running resistance of a car is set F and the speed thereof is set to V, a formula F=A+B.V+CV<2> (A-C are a constant) is formed. Therefore F is a quadratic equation of V and a function can be determined.

Title: Sludge treatment device suing magnetism
Inventor: KIHARA YASUHIKO
IPC: C02F11/12
Filed: 1987-12-24
Abstract: PURPOSE:To apply a magnetic treatment to sludge flowing through a flow path using a magnetic flux of comparatively low density, promoting a flocculation of sludge and decreasing a moisture content rate of sludge during dehydration by arranging a magnetism generating device outside a U-shaped magnetic treatment flow path. CONSTITUTION:Sludge is allowed to run downward from the top of either one of U-shaped magnetic treatment flow paths 2a, 2c, and shunted to the opposite side at the bottom. After this, the sludge is caused to flow upward. At that time, a magnet 4 is arranged as a magnetism generating device in a state where the flow paths 2a, 2c are sandwiched between N and S poles in the recessed parts on both sides of the flow path and the center. Sludge flocks are flocculated as they run through the flow path by the magnetic field effect generated by the arranged magnet 4, and the flocculation process is promoted to reduce the moisture content of sludge. If a significant amount of magnetism-sensitive substance sticks to the wall surface of the flow path as a result of sludge treatment for a specified time, the magnetic field is demagnetized by magnet 4, and a washing liquid is injected into the flow path from a spray nozzle 6 above the flow path to remove the sticking magnetism-sensitive substance. Thus the substance is discharged from a discharge pipe 7 at the bottom.
