Title: Monitor of dc servo motor and monitor system of robot
Inventor: SHIMODA KAZUYUKI
IPC: B25J19/06
Filed: 2001-11-12
Abstract: PROBLEM TO BE SOLVED: To predict a failure due to wear of the brush of a DC servo motor accurately and conveniently. SOLUTION: A DC servo motor 2 is subjected to PWM driving by a controller 1 connected through a feeder line 4. A sensor 3 measuring the current of a pair of feeder lines 4 collectively outputs a current difference Ia-Ib corresponding to a leak current Ir flowing through the insulation resistor Rz of the motor 2. The sensor output is compared with two difference threshold values Th1 and Th2 by comparison circuit 6 and 7 and, depending on the comparison results, a logic circuit 8 delivers an abnormal signal if the leak current is higher than the large threshold value Th1 and delivers a caution signal if it is between Th1 and Th2.  Since the leak current Ir is proportional to the insulation resistance if the drive current V is constant and the insulation resistance has a good relation with wear of brush, failure of motor due to wear of brush can be predicted accurately by monitoring the magnitude of the leak current.

Title: Method for monitoring refrigerant filling level
Inventor: DEMUTH WALTER
IPC: F25B45/00
Filed: 2001-11-29
Abstract: PROBLEM TO BE SOLVED: To provide a method for monitoring a refrigerant filling level, capable of surely sensing wrong filling with only slight expense. SOLUTION: The method of monitoring the refrigerant filling level comprises the step of monitoring the refrigerant filling level in a refrigerant cycle of an air conditioner, or a heat pump unit having the refrigerant to be operated within a supercritical range, depending upon a compressor and an operating point. The method further comprises the steps of monitoring the stop filling level at a compressor switch off time and/or monitoring an operating filling level at a compressor switch on time. At in-operation filling level monitoring time, a refrigerant overheat (dTu) is detected at an evaporator, and in the event of overheat time, underfilbing is inferred. At stoppage time, the pressure and a temperature of the refrigerant are detected.  Meanwhile, when a pressure (PKM) is below a lowest minimum pressure value (Pmin) or lower, or when a temperature (TKM) is a maximum saturation temperature value (TS) or higher and the pressure lies out of a settable target pressure range ([Pu, Po]), wrong filling is inferred. For example, it is used as a carbonic acid gas air conditioner of an automobile.
