Title: Ratio controller
Inventor: AOKI KAORU
IPC: G05B11/36
Filed: 1993-06-03
Abstract: PURPOSE:To enable two slave controllers to switch the cascade close state with no bump against a master controller while keeping a ratio between both slave controllers by placing two multipliers between the master and slave controllers respectively to set the ratios among them. CONSTITUTION:The signal with a slave controller 6 of the side A switched from a cascade open state to a cascade close state is converted into a one-shot signal by a one-shot signal generator 10. Then '1' is written into the ratio constant of the side A by a switch 8 of the side A. Then the output of a master controller 2 is set at the present set value of the controller 6 by a switch 11. Furthermore the value obtained by dividing the hitherto set value of a slave controller 15 of the side B by the present set value of the controller 6 is defined as a comparison constant 13 of the controller 15. Thus it is possible to continue the control based on the hitherto value while keeping a ratio between both controllers 6 and 15.

Title: Main rope hanging for 2:1 roping elevator
Inventor: KUNITO KAZUO
IPC: B66B7/06
Filed: 1998-05-15
Abstract: PROBLEM TO BE SOLVED: To provide a main rope hanging method for a 2:1 roping elevator which can reduce cost and allow high efficient replacement of a main rope. SOLUTION: This elevator is provided with a rope brake 13 engaged with a main rope 2 tensed between a wire drum 1 and a hoist sheave 5, and while the frictional force of the rope brake 13 is being adjusted, the main rope 2 is drawn from the wire drum 1 to be hung downward in a hoistway 3. The frictional force generated between the hoist sheave 5, the outer-periphery surface of a deflector wheel 6, and the main rope 2 can cancel part of the dead load of a U-shaped part of the main rope 2, or reduce a load imposed on the rope brake 13, thus it is possible to minimize the strength of the rope brake 13 for downsizing. The other end of the main rope 2 can be retained by relatively small effort, thus it is also possible to fine-adjust the amount for drawing the main rope 2 from the wire drum 1, and determine the appropriate length of the main rope 2 easily.
