Title: Feed mechanism
Inventor: SHIRATORI YOSHIO
IPC: B65H23/04
Filed: 1978-09-04
Abstract: PURPOSE: To prevent extension of or damage on a film-like dedium during letting off the medium from one take-up roller and winding up it around the other take- up roller by providing movable rollers for absorbing the tensile force.  
     CONSTITUTION: A film-like medium 1 is let off from a take-up roller 2a and wound up around a take-up toller 2b, the two take-up rollers 2a and 2b being rotated at the same speed. As the let-off amount at the roller 2a becomes different from that take-up amount at the roller 2b so that the tensile force on the medium 1 increases, a lever 6 moves against the biasing force of a spring 7 to urge movable rollers 3a and 3b toward a fixed roller 5, relaxing the tensile force. As the tensile force decreases, the lever 6 is moved by the biasing force of the spring 7 to urge the rollers 3a and 3b away from the roller 5, compensating for the decrease in the tensile force. With a motor 11 rotated in the reverse direction, the medium 1 is transfered in the direction of the broken-line arrow.

Filed: 1998-04-17
Abstract: PROBLEM TO BE SOLVED: To prevent an internal combustion engine from being rotated at a higher speed beyond a specified speed by making a decision that a fuel shut-off valve is defective. SOLUTION: This fuel injection device is equipped with a fuel shut-off valve disposed to a fuel feeding passage feeding fuel to a pump chamber to be expanded/contracted by the reciprocal movement of a plunger, and with a spill valve disposed to a spill passage releasing fuel to the spill passage from the pump chamber. When an internal combustion engine is suspended, the closing timing of the spill valve is hastened so as to allow the intake of fuel from the spill passage to be interrupted (step 210). After that, the fuel shut-off valve is closed so as to allow a fuel feeding passage to be interrupted (step 220). When the internal combustion engine still does not stop (step 230), it is decided that the fuel shut-off valve is defective in a state that it is opened to inform the deficiency.
