Filed: 1989-05-26
Abstract: PURPOSE:To prevent disabled control by providing two receivers and two batteries connecting to them respectively. CONSTITUTION:When either a receiver 1 or 2 is faulty, for example, the receiver 1 receives a command to return. In this case, the direction lope is for left turning only, the aircraft flies on a desired sky point by controlling the turning radius properly and the altitude is controlled so that the aircraft is not damaged even on landing or falling by using a left turning servo motor 4 and a right elevating angle servo motor 6 and the craft is recovered by stopping the engine by an engine stop servo motor 5. When the receiver 1 is faulty, the receiver 2 controls a left elevating angle servo motor 7, a right turning servo motor 8 and an engine rotation number control servo motor 9 to recover the aircraft. When any of batteries 11, 12, 13 and 14 is worn out, the aircraft is recovered by applying the similar control.

Title: Measuring method for leak width of liquid
Inventor: NAITOU HITOSHI
IPC: G01M3/16
Filed: 1981-08-24
Abstract: PURPOSE:To simply measure a leak width of liquid, by a method wherein a leak width of liquid is determined by a difference between a time, for which a pulse propagates over the whole length of a cable, detecting leakage of liquid from a change in impedance, in the case of liquid permeation, and a time for which it propagates in a similar manner in the case of no liquid permeation. CONSTITUTION:According to an instruction of a controller 2, a pulse from a pulse generator 1 is applied a detecting cable 3 running along an oil pipe line and the like, the pulse reflects from opposite ends of an oil leak part 4, and reflects also from the terminal of the cable 3 whereto a terminal impedance 5, being difference from the characteristic impedance of the cable 3, is connected. A sample hold time at a sample hold circuit 7 is controlled by the controller 2, and a waveform of a terminal reflection wave is detected through an A/D converter 8 to determine a time for which the pulse propagates the cable 3. A difference between a propagating time in the case of liquid leak and that in the case of no liquid leak is found, and this enables to perform a simple measurement of a leakage width corresponding to a change in the propagating speed of the pulse based on a change in impedance due to leakage.

Abstract: PURPOSE:To provide a dust collector which has only the advantages of a cyclone type and a bag filter type and permits the reduction in size by providing bag filters in an inside cylinder concentrical with a sealed outside cylinder, and providing flow regulating plates in the lower part between the outside cylinder and the inside cylinder. CONSTITUTION:The gas entering the dust collector through a gas inflow port 1 swirls and falls in the cylindrical space between an outside cylinder 15 and an inside cylinder 16. The heavier dusts among the gases 3 in the gas fall by the own weight, pass the inside of the clearances alpha for dust falling formed between flow regulating plates 18 and the inside circumferential surface of the cylinder 15 and are accumulated in the lower part in the cylinder 15. The lighter dusts 3 enter the holes 17 in the bottom plate 16A of the cylinder 16 and are captured by bag filters 12, whereby the filtration of the gas is thoroughly effected. Since only the light dusts are captured in the bag filters, the bag filters are less liable to clog. Since the gas trying to enter the holes of the inside cylinder from between the inside and outside cylinders is guided by the plates 18, the blowing up of the dust accumulated in the lower part in the outside cylinder by said gas is obviated; therefore, the height of the outside cylinder is made smaller and the size thereof smaller.
