IPC: F16J9/06
Filed: 1985-04-05
Abstract: PURPOSE:To improve sealing ability, by a method wherein a tongue piece is cut and risen in an internal projection and in a range, extended between coupling members, toward the external periphery side. CONSTITUTION:A tongue piece 7 is cut and risen in an internal peripheral projection 2 of a spacer expander and in a range, extended between coupling members 3 thereof, toward an external periphery side, and pressure collecting surfaces 71 are formed integrally with the tongue piece at upper and lower ends in the direction of an axis of the forward end of the tongue piece.

Title: Circuit diagram input device
Inventor: MORINAGA KAZUO
IPC: G06F17/50
Filed: 1989-03-23
Abstract: PURPOSE:To facilitate the circuit diagram input work and to prevent input and erasing of a branch point indicating symbol from being forgotton by automatically generating and displaying the branch point indicating symbol at a branch point or a connection point at the time of branching an already inputted signal line or connecting the end point of another signal line. CONSTITUTION:A diagram symbol reading-in means 7 reads out the diagram symbol indicated by an operator from a memory 4 and displays this diagram symbol on a picture display part 6 by a circuit diagram display means 8. When a signal line input means 9 indicates branch of an already inputted signal line or connection of the end point of another signal line to the already inputted signal line and changes the display of the circuit diagram display means 8, a branch point indicating symbol generating means 10 generates the branch point indicating symbol at the branch point or the connection point and displays it through the signal line input means 9 by the circuit diagram display means 8. When a signal line erasing means 11 erases the signal line, the displayed branch point indicating symbol is erased. Thus, the operation is facilitated and input and erasing of the branch point indicating symbol are prevented from being forgotton.

Title: Method and device for controlling travelling of motor driven partition
Inventor: KOMAKI HIROSHI
IPC: H02P3/06
Filed: 1998-03-05
Abstract: PROBLEM TO BE SOLVED: To prevent reverse running by stopping the drive of a motor when the drive amount of a drive part measured at intervals of a prescribed time is displaced in the contrary direction to the setting direction. SOLUTION: A travelling device hanging a panel is provided in a rail fixed on a ceiling. Next, when the travelling device receives a travelling instruction from a host computer, a motor 28 is driven, the travelling device is started, and a memory 43 stores the counted value of a timer 42 and a rotary encoder 36 at the time. Next, a microcomputer 41 detects the count value of the rotary encoder 36 at the time point when a preset time (for example, 0.5 seconds) passes and compares it with the stored count value while the travelling device reaches a preset planned stop position. In the case where it judges that it is large, travelling of the travelling device is continued, in the case where it judges that it is not large, it judges that the travelling device is reversely travelling and the drive of the motor 28 is stopped. Thereby the reverse travelling of a panel can be prevented.
