Patent JP-H099679-A (JP)
Title: Motor controller
Inventor: TSUBOUCHI TOSHIKI
IPC: H02P7/28
Filed: 1995-06-21
Abstract: PURPOSE: To feed power adequately from a DC power supply used for a motor with a large output voltage to a law-cost semiconductor integrated circuit with low withstanding voltage in a simple low-cost setup, by feeding the power from the DC power supply to a voltage control means in the semiconductor integrated circuit through a current control means. CONSTITUTION: A large output voltage VM from a DC power supply 1 is fed to a power input terminal 6 of an IC 1 through a resistor 8 (resistance of Ra). A Zener diode 9 between the input terminal 6 of the IC 1 and a GND terminal 7 switches on, and a terminal voltage Vcc of the power input terminal 6 is limited to a Zener voltage VZ that is intrinsic to the Zener diode 9 by the on-state of the diode 9. When the voltage Vcc of the input terminal 6 is entered in an input terminal of a limiting circuit 5, the limiting circuit 5 can be put in an operational state. The level of the Zener voltage VZ is set to a level below a withstanding voltage of the IC1 but enough to operate the control circuit 5;.

Title: Rotating angle detector
Inventor: NAGAHAMA TAKAHIDE
IPC: G01D5/245
Filed: 1987-06-23
Abstract: PURPOSE: To improve the accuracy of detection by comparing the actual detection signal from an absolute angle detector and a stored current off time detection signal when a power supply is turned on again and correcting a power supply off time count value to an actual count value corresponding to the actual absolute rotating angle.  
     CONSTITUTION: The detection signal from a resolver 4 and the count value by a reversible counter 8 are respectively stored in 1st and 2nd memories 9 and 10 when the power supply of the device is off. The actual detection signal from the resolver 4 and the power supply off time detection signal in the memory 9 are compared by a comparator 11 when the power supply is turned on again. The power supply off time count value in the memory 10 is then corrected to the actual count value corresponding to the actual absolute rotating angle by a corrector 12 according to the difference therebetween. The absolute rotating angle of a rotating member 1 is, therefore, exactly detected as the sum of (prescribed rotating angle) × (actual count value obtd. by the correction) and the actual detection signal from the resolver 4 after the power source is turned on again even if the member 1 turns during the time from the power source off before the power source is turned on again. Namely, the need for matching the origin at the time when the power source is turned on again is eliminated and the accuracy of the detection is improved.

IPC: G06F13/00
Filed: 1985-07-15
Abstract: PURPOSE:To assign equally the change of inter-system communication to both systems by providing a scan circuit which stops the alternation of identification numbers to hold the identification numbers being outputted in case an inter-system communication request is delivered from one of both systems, then sends a communication permitting signal to both systems. CONSTITUTION:A scan circuit 6-0 sends an identification number (id) which alternates the identification numbers (n) of systems '0' and '1' in a prescribed cycle to the communication control circuits 4' of both systems together with a synchronizing signal (snc). When a communication request signal (rq) is received from one of both circuits 4', the signal (id) is fixed to the number (n) under transmission and at the same time the communication permitting signal (tk) is sent to both circuits 4'. Thus the signal (rq) is transmitted from only the system having the number (id) coincident with the number (n) of its own system. In such a way the priority processing is omitted and also simplifies the constitution. Then both systems request the communication between them only when the periodically alternating signal (id) is coincident with the number (n) of own system to obtain the using right of an inter-system communication bus 5. In such a way, the using right of the bus 5 is assigned equally to both systems.
