Title: Detection circuit for broken line from encoder
Inventor: NAKAZAWA KOICHI
IPC: H04B3/46
Filed: 1992-01-20
Abstract: PURPOSE:To detect the disconnection of transmission line from an encoder with a few line numbers by judging the broken transmission line when no current flowing to the transmission line is detected. CONSTITUTION:The circuit 1 supplies a current depending on the ON/OFF of a pulse signal of an encoder to a transmission line 11. The circuit 2 reproduces the different current into an ON/OFF signal. When a current detection circuit 3 detects no current flowing, it is judged that the transmission line 11 is in disconnection. That is, the resistance of a base resistor 32 and a collector resistor 33 of a switching transistor(TR) 31 is selected so that a current flows to a base of the TR 31 even when an output TR 12 of the encoder is switched and a potential of a collector exceeds a threshold voltage of an inverter 34. When the transmission line 11 is in disconnection the TR 31 is turned off because the base potential reaches a Vcc and an output of the inverter 34 changes from a low level to a high level, resulting in indicating the disconnection.

Title: Recovering method for high-reliability computer system
Inventor: MIYAO TAKESHI
IPC: G06F11/20
Filed: 1991-01-25
Abstract: PURPOSE:To eliminate various trouble due to the recombination of processors by disconnecting some of the processors in the case of trouble occurrence and switching all the processor into another new processor group at the time of recovery. CONSTITUTION:Three MPUs(microprocessing unit) of a BPU(basic processing unit) 2A are normally in operation. If trouble occurs to the MPUC during the execution of a process B, it is disconnected and the operation is carried on by the MPUA and MPUB. The printed board of a new BPU2B is inserted into a free slot in response to abnormality information by the MPUA, and then the respective MPUs in the new BPU2B diagnose themselves; and the process is transferred from the old BPU2A to the new BPU2B and a process D is carried out according to the result of majority decision making by the three MPUs. Thus, the process is taken over by carrying on the operation of the BPLT up to a good switching point of time or a repair maintenance period, so that the takeover is done at the most suitable point of time of software.

IPC: B60L9/16
Filed: 1989-01-18
Abstract: PURPOSE:To prevent large runaway of an inverter frequency at the time of occurrence of slip by limiting a change rate of electrical angular velocity of an induction motor. CONSTITUTION:A current controller 2 outputs a slip frequency command value so that a current detected by a current detector 8 may accord with a current pattern generated by a current pattern generator 1.

An adder 3 adds up the slip frequency command value and an output of the electrical angular velocity change rate limiter 13 and outputs a value thus obtained to a V/F-constant controller 4 as an inverter frequency command. The V/F-constant controller 4 controls a PMW control voltage type inverter 6 through a PMW pulse generator 5, thus conducting control of the speed of rotation of the induction motor 7. By the operation of the electrical angular velocity change rate limiter 13, a sharp increase of an inverter frequency is controlled even when slip occurs.
