Title: Timing control system
Inventor: KIUCHI YUKIO
IPC: G06F1/12
Filed: 1978-08-14
Abstract: PURPOSE:To control timing for periodical high-precision signal transmission and reception by indicating transmission and reception of a corresponding signal at fixed timing. CONSTITUTION:Once magnetic bubble channel MBCH is actuated, a microprogram in control memory CM is read out by microprogram sequence circuit SEQ to microinstruction register CMIR and then executed. From OSC, two kinds of clock C0 and C2 are generated to supply an insterruption signal to SEQ. These two kinds of clocks are out of phase and generated in the middle point between the both. Now, when the TOS0 signal of magnetic bubble unit MBU0 is expected to be sent out, a fixed timing value is previously stored by the microprogram and the fixed timing can precisely be grasped and set by performing subtraction by each external clock C0 making an interruption, so that the transmission and reception of signals can be attained at accurate timing.

Title: Method and device for winding with leader sheet
Inventor: KATAOKA AKIRA
IPC: B65H19/28
Filed: 1983-06-06
Abstract: PURPOSE:To prevent the efficiency of winding of a prescribed quantity of a sheet as a roll from falling, by cutting off the sheet in a moving passage during the stoppage of the winding, bonding a leader sheet to both the cut-off ends of the sheet in the moving passage, splitting the leader sheet half, and resuming the winding of the sheet with the upstream cut-off end. CONSTITUTION:A sheet S is cut-off along its width in a straight moving passage 3. The front and rear edges of a leader sheet 7 are bonded to the cut-off ends of the sheet S. A sheet roll Sa is then slowly rotated to move both the sheets. When the prescribed cut-off portion of the leader sheet 7 has come to a prescribed sheet cut-off position 13, the rotation of the sheet roll Sa is stopped and the leader sheet 7 is split to a front and a rear portions together with a tape 19' by a cutter 13. The holder of the cutter 13 is moved forth further to push and bond the cut-off end of the leader sheet 7 to a new winding shaft 10. The leader sheet attaching work is thus performed in a high-efficiency winder without much lowering its efficiency. The efficiency of the leader sheet attaching work and the quality of the product resulting from the work are improved.
