Title: Device for assuring of the door closure in a coke furnace
Inventor: IWATA HIROYOSHI
IPC: C10B25/08
Filed: 1980-06-24
Abstract: PURPOSE: Whether the bolt on the furnace door is correctly fitted to the bolt receiver on the furnace wall or not, or whether the bolt is completely removed from the bolt receiver or not is detected by signals to assure the results with high accuracy  and reliability than by eye observation.  
     CONSTITUTION: When the furnace door covers the opening and the bolt on the furnace door a is fitted to the bolt reaceiver b 1  and b 2 , the device for determining the reference point of the displacement in the unit for measuring the vertical displacement is lifted along the vertical line R-R' to come into contact with the lower end r of the bolt receiver b 1  and the measuring device 2 is made to fall down along the line R-R'. When the one end a 1  of the bolt correctly connects to the receiver b 1 , the variable transformer generates a power corresponding to the distance H between the reference point y 1  and the measured point y 2 . In the horizontal direction, the power corresponding to the distance J between the reference device 39 and the measuring device 41 is also generated, when they are correctly fitted.

Filed: 1989-04-05
Abstract: PURPOSE:To easily and rapidly select and change many electric wires by providing plural pieces of connected guide nozzles intermittently movably in the direction perpendicular to the plane of a pair of feed rolls. CONSTITUTION:Leveling rolls 25 are opened and the feed rolls 26 are rotated backward to retreat the electric wire by as much as the thickness of a guide plate 32 and to release the front end of the electric wire from an electric wire insertion hole 32a. The feed rolls 26 are then opened and the guide nozzle 24 used thus far is opened. The pull out of the electric wire is prohibited by the effect of an electric wire retaining pin 27 at this time. A timing belt 21 is turned and the guide nozzle 24 of the electric wire to be used next is positioned between the feed rolls 26 and between the leveling rolls 25. After the feed rolls 26 and the leveling rolls 25 are closed, the electric wire is supplied and measured in length while the electric wire is leveled. The electric wire is finally cut by a cutting blade 33 and is adjusted to a desired length. The cutting operation of the electric wire is automatically executed in an extremely short period of time in this way.

IPC: H02P8/00
Filed: 1993-04-13
Abstract: PURPOSE:To smoothly rotate a rotor with a simple circuit by eliminating the stable balance point at the second position once or more, in the middle of a magnetic pole reaching the second position from a first position, and also generating a stable balance point in the position closer to first position with respect to the magnetic pole, and generating a stable balance point in the second position again. CONSTITUTION:In case of rotating the magnetic pole of a rotor from a position P0 to that P1, with the output cycle of a command pulse E as the cycle of four outputs per displacement of the basic step angle of a rotor, a distributing circuit 12 energizes an A-phase coil 52 and a B-phase coil 54 in the first place so as to deter the attenuating oscillation at a point P0. Next, it starts the rotor by energizing the B-phase coil 54 and the C-shape coil 56, and then, it weakens the angular speed of the rotor going to the position P1, passing the position of the B-phase coil 54, by weakening the B phase, and next it puts a stable balance point in the position P1 by energizing the B phase coil 54 and the C-phase coil 56, and converges the specified magnetic pole of the rotor into the position P1. Hereby, the inertia of the rotor is restrained, and the rotation can be smoothed.
