Title: Loop network system
Inventor: MASUDA MICHINORI
Filed: 1985-09-30
Abstract: PURPOSE:To repair the fault of a transmission system and to establish a communication path between nodes solely without using a special frame by setting an address inherent to left/right loop transmission lines to each node and providing a data detection circuit. CONSTITUTION:The inherent address is given to communication control sections 48, 49 of each node. If a fault takes place at a location shown in figure, each node detects the token missing on a left/right transmission line by system supervisory sections 54, 55, the state is changed from an NRM state 90 to a CL-TK- TX state 91 in the state transition figure and a claim token frame 60 is sent. The frame 60 of each node is passed only when the sender address is larger than or equal to the address of the reception node. As a result, nodes 2, 3 not detecting a data and a node 4 having a maximum address continue to send the frame 60, and the other node enters the state 92. The nodes 2, 3 output an input signal from a transmission line opposite to that from which the fault is detected and loopback is formed to send a frame 60 to both the left/right transmission line. Thus, the node having the maximum address issues a token again and all the nodes restore to the NRM state 90.

Abstract: PURPOSE:To effectively use a protecting region for writing a data in case of carrying out the data and the like received from an external device by providing a register for storing an information showing a writing protection region, a comparison circuit and a resetting circuit. CONSTITUTION:A terminal unit 30 receives a basic data by a receiving circuit 31 through a communication line 20 from an external device 10, stores in a memory device 33 under a control of a control section 32 and a required processing is carried out. In this case, a register 34 for storing an information (writing protection region address) showing a writing keeping region of the memory device 33 and a comparison circuit 35 comparing a relation on an importance of an access address of the memory device 33 and a reset circuit 36 are used. Thereby, even when the content of the basic data stored in the memory device 33 is changed, a correction for a writing in the protecting region of the register 33 is prevented and a violent operation of the control section 32 can be avoided. Since an error position can be checked, the protecting region can be effectively used.

Title: Position controller
Inventor: SAKAMOTO KEIJI
IPC: B25J9/16
Filed: 1986-09-16
Abstract: PURPOSE:To reduce deviation between a position command signal, and a position signal, and to accelerate responsiveness, by adding a differentiator on the input side of an integrator in a position control system, and further adding a factor term. CONSTITUTION:In a closed loop transfer system having the spring factor K, and the differentiation term S of a system, since a transfer function Gs equals to K/(K+S), and a deviation E(s) equals to the difference between the position command signal C(s) and the position signal y(s), the deviation E can be set as C-y=0 by adding the differential value of an input signal on the front of the integrator. Then, control loops alphaS and beta are added as usual. At this time, a deviation quantity E(s) can be obtained by equation through the use of the inertia Jm of a motor, and spring factors K1 and K2. At such a time, furthermore, by selecting (alpha) as 1, and (beta) as K2, the E(s) can be simplified as E(s)={JmS<3>/(KK1+K1S+JmS<3>)XC(s). By such constitution, the deviation quantity between the position command signal, and the position signal can be reduced at fast responsiveness.

Title: Bpf device
Inventor: YAMAMOTO RYUJI
IPC: H03H11/04
Filed: 1995-08-25
Abstract: PROBLEM TO BE SOLVED: To pass only a signal of a necessary frequency band by setting up the Q value of a 3rd trap circuit lower than that of a 1st trap circuit and setting up the Q value of a 4th trap circuit lower than that of a 2nd trap circuit. SOLUTION: A 1st trap means 10 is constituted of connecting trap circuits 11, 12 in series, the center frequency of the circuit 11 is set up to 1.7MHz and its Q value is set up to a higher value as compared with the trap circuit 12. Although an 1.7MHz component can be sufficiently attenuated in the constitution, bounce is generated and a frequency component higher than 1.7MHz is produced. Thereby a trap circuit 15 reducing its Q value is prepared to remove an unnecessary part generated in the bounce part. A 2nd trap means 14 is constituted of connecting trap circuits 15, 16 in series and a BPF 9 is arranged on the prestage of the trap means 10. Since the Q value of the trap means 14 is low, an unnecessary frequency component is not produced also on the final stage. Consequently L and R channels can be accurately separated.
