Title: Tape measure
Inventor: MIZUNO ICHIROU
IPC: G01B3/10
Filed: 1982-12-28
Abstract: PURPOSE:To prevent the free springing of a wire from a winding reel and to enable ordery step-winding of the wire on the winding reel by connecting an operating handle with an anti-reversing means and providing a means for guiding the winding. CONSTITUTION:An engaging groove 47 which is made gradually deeper in a winding direction is formed on the end face of a disc 42 which is turned integrally with a winding reel 21 in a tape measure which displays the drawing- out rate of a wire 2 on a counter 75 having a zero resetting function. An engaging pin 53 is energized with a mounting disc 43 toward the groove 47 by a spring 52 to prevent the free rotation of the reel 21 in the rewinding direction thereof. A means 4 for guiding the winding is constituted of an eccentric ring 62 which is eccentrically turned according to the winding of the wire. When the reel 21 is turned in the winding direction, the wire 2 is guided back and forth in the axial direction of the reel 21 by the ring 62 thereby the wire 2 is orderly step-wound on the reel 21.

Abstract: PURPOSE:To realize the titled decoder by a comparatively small capacity of ROM by providing a syndrome generating means, a syndrome T-time cyclic shift means' a syncrome cyclic shift means, an error correction means, an N-adic counter and an N-word buffer. CONSTITUTION:An output of a gate 18 is all brought into zero by a start pulse outputted from the N-adic counter 30, and as soon as a syndrome of a precedingly received word is reset, a head word of a received word is inputted from an input 1 to a delay element 7. Then contents of the delay element 7 being subject to multiplication by a<1>-a<3> multiple devices 9 11 are added to the inputted received word at an exclusive OR 2 and inputted to the delay element 7 once more. Simultaneously, the received word is inputted to an N- word buffer 29 at each clock. Thus, the output of the delay element 7 receiving the N-th received word is inputted becomes a syndrome. The syndrome shifted cyclicly by T-time is inputted to a delay element 8 while being multiplied by a<1>, a<2>, a multiple devices 15-17 and inputted to an exclusive OR 3. Then an erroneous pattern e0 is calculated and outputted from an exclusive OR 5.

Title: Method for monitoring plant and device therefor
Inventor: ITO MASAMI
IPC: G05B23/02
Filed: 1994-09-26
Abstract: PURPOSE: To provide a plant monitoring method and device which can automatically search for the factor of abnormality of a plant operation without using any program tool. CONSTITUTION: A program equal to a program 121 that is carried out by a controller 1 is stored also in storage 24 of a monitoring device 2 (241). When an abnormality signal is detected in a normal monitor mode, the program stored in the storage 24 is retrieved with an abnormality signal used as a key. Then a signal serving as an arithmetic input of the abnormality signal is extracted as a candidate signal of the abnormality factor together with its composition attribute and then managed in a factor candidate table 243. Furthermore, the present signal states are read out of a data part 122 of the controller 1 for each candidate signal and compared with the attribute. Thus a signal unmatched with the composition attribute is decided as factor signal of non-composition among those candidate signals.  If a factor signal is the internal signal that is produced in the controller 1, the factor signal is recursively retrieved.

Title: Motor controller
Inventor: SETO MAKOTO
IPC: H02P27/08
Filed: 1984-10-31
Abstract: PURPOSE:To suppress the variation in the voltage due to the abrupt change of a load torque by detecting the DC current of a voltage inverter by an inverter input DC current detector to adjustably feed back the output current. CONSTITUTION:When the load of a motor 6 varies and the torque current alters, it is detected by a DC current detector 5c, and the detected value is led to a current controller 10. Thus, the variation in the torque current is rapidly supplied from a controllable rectifier 1. Thus, the variation in the voltage of a DC voltage detector 5b is largely reduced as compared with the conventional case. Thus, when the load torque alters, the voltage variation is suppressed to obtain a rapid speed response, and the withstand voltage of the capacitor 2b of the DC intermediate circuit 2 can be reduced, thereby reducing the cost.

Title: Composite type flow meter
Inventor: OISHI YASUHARU
IPC: G01F7/00
Filed: 1990-09-03
Abstract: PURPOSE:To detect gas leak in an extremely short time by controlling a shut-off valve by judging from a flow signal fed from a first flow meter which allows a small amount of flow to be measured instantly and a second flow meter which allows a large amount of flow to be measured and by detecting leak according to change in output of the first flow meter. CONSTITUTION:A microcomputer 4 measures flow by inputting a flow signal from each flow sensor 1 and a Karman flow meter 2, controls opening/closing of a shut-off valve 3 by judging from the flow state, and then detects leak according to output change of the flow sensor 1. When the shut-off valve 3 is closed, the flow gradually begins to be reduced when leak is located at a downstream b of a gas meter 11. Also, when there is no gas leak, gas shift stops at the moment when the shut-off valve 3 is closed so that an output of the flow sensor 1 momentarily reaches 0, thus enabling the microcomputer 4 to detect presence/absence of gas leak positively by judging output signal of the flow sensor 1.
