IPC: G01G19/16
Filed: 1998-02-17
Abstract: PROBLEM TO BE SOLVED: To accurately detect a suspension load by using each pressure sensor detection signal of an arm cylinder and that of a bucket cylinder when a boom cylinder is at a specific stretching stroke end and an arm droops, respectively. SOLUTION: A suspension load operation is made in three steps according to the posture of an operation arm 8 by an operation device 50. More specifically, the detection signal of pressure sensors 40 and 41 of a boom cylinder 16 is normally used for the detection signal of the pressure sensors. Then, when the boom cylinder 16 becomes a specific stretching stroke end, the detection signal of the pressure sensors 40 and 41 fluctuates so that the detection signal of the pressure sensors 42 and 43 of an arm cylinder 18 for supporting a suspended load Wx is used for the detection signal.  When the gravity of an arm 12 droops in a specific angle range for a perpendicular line 11a that passes through an arm rocking center 11 in the same state, the pressure of the arm cylinder 18 fluctuates, thus calculating the suspension load Wx in each state by the detection signal of the pressure sensors 44 and 45 of a bucket cylinder 20 for supporting the suspension load Wx for the detection signal.

Title: Driver for sensorless brushless motor
Inventor: TAMAKI SATOSHI
IPC: H02P6/21
Filed: 1993-02-24
Abstract: PURPOSE:To allow commutation at an appropriate timing without requiring any delay pulse by correcting the exciting time such that phase shift is eliminated between the rotary position of rotor and conduction of coil. CONSTITUTION:Conduction is started forcibly for each phase of a three-phase motor. Excitation is performed by dividing one period of 360 deg. into 12 patterns of 30 deg.. A microprocessor 1 observes the waveform of voltage induced during nonconducting period and corrects the exciting time such that the phase shift of rotor is eliminated. A comparator 4 compares the induced voltage with an applying voltage of motor while dividing into tri-levels at a specific timing and phase lock control is performed based on the comparison results. Consequently, stabilized operation of rotor equivalent to a brushless motor equipped with a rotary position sensor can be achieved. Furthermore, rotation synchronized with a command speed 14 can be achieved by comparing the speed command with an averaged exciting time and varying the duty of PWM signal.
