Title: Control method for bilateral master-slave manipulator
Inventor: TAMURA MASAYOSHI
IPC: G05D3/12
Filed: 1988-05-06
Abstract: PURPOSE:To enable smooth manipulation while an operator senses true reaction force by returning a value obtained by subtracting an integrating operation amount of a slave servo system from output of a torque sensor as reaction force to a master servo system when a slave arm is brought into contact with a fixed portion. CONSTITUTION:When a detector 8 detects that a slave arm is brought into contact with a fixed portion, a deviation  THETA between a master axis angle THETA1 and a slave axis angle THETA2 which are detected by sensors 1, 2 is increased, so that the slave axis velocity (v) becomes substantially zero to close a switch 9. A computing element C' obtains a deviation  THETA in a controller C and subtracts it from output (reaction force) of a torque sensor 5 for detecting torque of a motor 4 to be returned to a motor 3 of a master servo system. Accordingly, an operator can conduct smooth manipulation while sensing true reaction force where actual phenomenon is influenced.

Title: Apparatus for measuring engine oil consumption
Inventor: OMORI YUKIMITSU
IPC: G01F3/36
Filed: 1989-05-01
Abstract: PURPOSE:To improve the measuring accuracy of the amount of consumption by detecting an engine oil level based on the measured pressure difference, and controlling an oil feeding device. CONSTITUTION:An air pump 15 is operated by the control of a measuring control unit 22 and feeds compressed air into an accumulator tank 16. The air is discharged into the vapor-phase part at the upper part of an engine 1 from the tank 16 by way of a vapor-phase side air pipe 18 through a pressure detecting joint 4. At the same time, the air is discharged in engine oil in an oil-level detecting chamber 8 by way of a liquid-phase side air pipe 20 through the tip opening part of the pipe 20. The pressure difference between both pipes at this time is measured. The measured pressure difference  P is the product of rho (density of the engine oil), (g) (acceleration of gravity) and (h) (height from the end of the pipe in the engine oil layer to the oil level). Since rho and (g) are known, (h) can be operated and detected. For example, when the supply control for the engine oil is a constant supplying system, the unit 22 supplies the engine oil so as to keep the (h) constant. Then, the amount of supply corresponds to the amount of the oil consumption.
