a plate holder for holding the front end of the plate with suction air supplied from a suction air source, and
a locking portion for locking the rear end of the plate.
4. An apparatus according to claim 3, wherein said releasing means releases the held front end of the plate by disconnecting supply of the suction air to said plate holder.
5. An apparatus according to claim 4, wherein
said plate holder is supported to be movable between a wait position and an inserting position for inserting the plate into said plate fixing unit, and
said releasing means releases the held plate when said plate holder moves to the inserting position while supporting the front end of the plate.
6. An apparatus according to claim 5, wherein
said apparatus further comprises
a first rotary member which is rotatably supported by said plate holder and comes close to said plate fixing unit when said plate holder moves to the inserting position,
a second rotary member supported to be rotatable and movable, and
moving means for moving said second rotary member in a direction to come close to said first rotary member when said plate holder moves to the inserting position, and
said first and second rotary members clamp the plate when inserting the plate into said plate fixing unit.
7. An apparatus according to claim 6, further comprising
a cover having a window to cover a front surface of a plate cylinder,
a swing plate to which said plate holder is fixed and which is swingably supported at an upper end of said window, said plate holder being located at the wait position when said swing plate covers said window, and at the inserting position when said swing plate comes close to the plate by a swing motion, and
a press roller for pressing the plate against an outer surface of said plate cylinder when inserting the plate.
8. An apparatus according to claim 5, wherein
said apparatus further comprises a swing lever for rotatably supporting said press roller at a distal end thereof,
said first rotary member is rotatably supported at the distal end of said swing lever,
said second rotary member is rotatably supported by said swing lever through a support member, and
along with a swing motion of said swing lever, when said second rotary member moves in a direction to come close to said first rotary member, the front end of the plate held by said plate holder is clamped between said first and second rotary members.
9. An apparatus according to claim 5, further comprising a positioning pin which engages with the front end of the plate, when said plate holder is at the wait position, to position the plate.
10. An apparatus according to claim 9, wherein
said apparatus further comprises a cover having said positioning pin to cover a front surface of a plate cylinder, and
said positioning pin disengages from the front end of the plate when said plate holder moves to the inserting position.
11. An apparatus according to claim 2, further comprising a guide member which, in a wait mode, supports a portion between the front and rear ends of the plate held in a flexed state and, in a plate insertion mode, guides the plate which moves by the elastic restoration force thereof toward said plate fixing unit.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. A transformer comprising a primary and a secondary coil wherein the secondary coil provides an outer secondary flux path route which isolates the primary coil from secondary coil BEMF induced flux, further comprising a secondary coil current delay wherein the induced flux predominates below a critical minimum frequency \u03c9c resulting in a single sinusoidal wave in the equivalent circuit and wherein further, above \u03c9c, the coil produces an AC pulse at the primary current sine wave crest TDC wherein the value of \u03c9e is achieved through tuning, wherein said delay further comprises a 90 degree secondary current delay in which the secondary current waits until the primary current has peaked at TDC \u201cof the flux\u201d (\u2018top dead center\u2019 or \u2018TDC\u2019) discharging flux.
2. The transformer of claim 1 wherein the secondary coils each provide the required on load flux magnitude increase needed to deliver sustained power to the load.
