Title: Bottom take-out type automatic paper feed device
Inventor: MORIKAWA SHUICHI
IPC: B65H3/46
Filed: 1990-03-26
Abstract: PURPOSE:To release the load of a separating pad so as to reduce the sheet clamping force of feed rollers during sheet feed, by separating a separating pad from a paper feed roller when a sheet fed onto a paper feed path is clamped by the feed rollers. CONSTITUTION:The lowermost one of sheets 8 stacked on a sheet bed 1 passes through a gap between a paper feed roller 2 and a separating pad 4 and is them clamped between feed rollers 7. Then, the paper feed roller 2 and the separating pad 4 are separated from each other so as to release a feed load caused by the friction force of the separating pad 4. These subsequent to the first one of the sheets which tends to enter into a paper feed path 6 since the paper feed roller 2 and the separating pad 4 are separated from each other, are checked at their leading edges by an extended return pawl 31, and are returned upstream from the abutting point (b) between the paper feed roller 2 and the separating pad 4 due to movement in a direction opposite to the paper feed direction. Thus, the feed of the sheets 8 by the feed rollers 7 is carried out in a condition such that the paper feed roller 2 and the separating pad 4 are separated from each other as mentioned above, and those subsequent to the first one of the sheets 8 are inhibited from entering into the paper feed path 6.

IPC: F02D15/02
Filed: 1986-04-07
Abstract: PURPOSE:To prevent knocking of an engine while suppressing its output decrease, by determining a compression ratio-switching boundary value from an engine speed and an intake air quantity and correcting the compression ratio-switching boundary value, when switching is performed from high compression ratio to low compression ratio, so as to quicken the switching to the low compression ratio. CONSTITUTION:An engine, equipped with a variable compression ratio mechanism, sets a high compression ratio operation region and a low compression ratio operation region from a relation between an engine speed, intake air quantity and its ratio to the engine speed. And the engine, in which a boundary value of the both regions is corrected when switching is performed from the high compression ratio region to the low compression ratio region, quickens the switching to the low compression ratio. That is, an electronic control unit 23, which inputs the engine speed NE and the intake quantity Q, discriminates the operation region, but the compression ratio is decided by performing a correction in which a value of b(constant)Xphi is added to Q/NE when a throttle opening speed phi is in a predetermined value or more.
