Title: Cpu self-monitoring circuit
Inventor: FUJINAGA SEI
IPC: G06F11/30
Filed: 1990-09-30
Abstract: PURPOSE:To assure the working of a CPU against any kind of faults by providing a reset signal output part to output a signal to a reset terminal of the CPU with use of the signal received from a pattern detection part. CONSTITUTION:A pattern detection part 20 compares the fixed pattern outputted from an IO port of a CPU 40 with the fixed pattern outputted from a fixed pattern output part 30. The output of the part 20 is inverted only when the coincidence is obtained between both patterns. Then a monostable multivibrator 50 is actuated. Therefore the output of the part 20 is never inverted as long as the CPU 40 sets even once the output of a fixed patter. Then a reset signal is sent to the CPU 40 from the multivibrator 50. Thus the CPU 40 can be instantaneously reset. As a result, the working of the CPU 40 is assured to any kind of faults.

IPC: H02P27/06
Filed: 1999-09-16
Abstract: PROBLEM TO BE SOLVED: To drive an efficient AC motor by switching of control, without using a map which requires many experiments. SOLUTION: This drive controller uses a PWM(pulse-width modulation) current control mode and a rectangular wave voltage phase control mode selectively by means of a switch 28. At this time, when it operates in the rectangular wave voltage phase mode, this switches the control over to the PWM current control mode, when an absolute value |ϕi| of the actual current phase supplied to a motor 38 falls under an absolute value |θ0| of the prescribed switching current phase. The prescribed switching current phase θ0 is provided with a phase, where for example, torque/current ratio becomes a maximum.  Conversely, when it is in operation in the PWM current control mode, this switches the control over to the rectangular wave voltage phase control mode, when the amplitude |V| of the voltage supplied from a current controller 14 to a PWM circuit 30 exceeds the prescribed switching voltage amplitude V0. For the prescribed switching voltage amplitude V0, limiting voltage at which, for example, the PWM current control is set which can be performed stably.
