Title: Loop transmission device
Inventor: YOKOTA KAZUYUKI
IPC: H04L5/22
Filed: 1983-03-25
Abstract: PURPOSE:To attain transmission and reception of accurate data completely in synchronism by transmitting a special bit train different from a bit train of a flag displaying an opposite station to a loop transmission network. CONSTITUTION:A signal pattern flowing to a transmission network is as shown in Figure, when a flag 13 of a synchronizing signal is transmitted from a master station 8 and a header 15 displaying the opposite station and a data 17 are transmitted from stations 8-11. Each station is activated in synchronizing with the synchronizing signal 14, detects the header 15 displaying the own station, fetches the data 17 addressed to the own station and transmits it to a terminal device 12. If the bit train of the header 15 and the data 17 is identical to that of the flag of the signal 14, since the out-of-synchronizm occurs by erroneously recognizing them as the signal 14 and the transmission/receiving of normal data is not attained, the specific fixed bit train different from the bit train of the flag 13 is inserted to the beginning of the header 15. Thus, mis-recognition of the header 15 as the synchronizing signal is avoided in this way and the complete synchronism is attained, allowing to transmit and receive data accurately.

Title: Method for taking-up of film
Inventor: FUJITA TETSUO
IPC: B65H23/032
Filed: 1984-03-19
Abstract: PURPOSE:To prevent a film from offset stacking and to redistribute the unevenness of film winding thickness by moving the periphery of traverse smoothly back and forth with the automatic change in the amplitude of traversing during the period of winding operation. CONSTITUTION:When a film 17 is being taken out, a winder 15 traverses in the X direction of the film, the rate of traversing is controlled by a throttle valve 26 based on signals from a control unit 27 so that the rate will be minimum at a point of both ends for return. The amplitude of traversing is controlled in such a manner that it changes slowly and repeatedly between l3 and l4 of the amplitude. This is effected by controlling either the operating time or the actuated displacement of a cylinder 23 which is controlled by a selector valve 25 based on signals from the control unit 27. Accordingly, the film traverses along a smooth line 28 such as a sine curve and others with the smooth change in the amplitude between l3 and l4. Effect on a rolled product 21 at a point of the zero traversing rate, therefore can be dispersd, as the amplitude of traversing changes smoothly and continuously.

Title: Dc motor controller
Inventor: KAMIYA TOSHIKAZU
IPC: H02P7/29
Filed: 1993-03-11
Abstract: PURPOSE:To control a DC motor without shutting it down even if a switching element fails which controls the DC motor through a chopper. CONSTITUTION:A switching element drive circuit 19 turns on or off an SIT 15 and detects the source voltage simultaneously with turning it on or off. The SIT 15 is kept off if it fails to close, causing the source voltage to be equal to the voltage of a battery 14. If short-circuited, the SIT 15 is kept on, causing the source voltage to be almost zero volt (because it becomes almost equal to the drain voltage). A microcomputer 20 checks the SIT 15 for failure and its contents. When the SIT 15 has not failed, the microcomputer controls the DC motor through a chopper. If the SIT 15 is short-circuited, the microcomputer turns on (separated off) a contactor 12 through a contactor drive circuit 26 to control a loading motor 11. If the SIT 15 is kept open (fails to close), the microcomputer stops controlling the loading motor.
