Title: Lock-up control device for automatic transmission
Inventor: TAKIZAWA SATORU
IPC: B60W10/10
Filed: 1999-09-30
Abstract: PROBLEM TO BE SOLVED: To eliminate control dispersion as well as prevent a hunching of lock-up so as to realize stable lock-up control, in the case where lock-up is prohibited when an oil temperature of a transmission is low or when an temperature of engine cooling water is low.

Title: Removing method of continuous sheet looseness for printer
Inventor: MAEKAWA TAKASHI
IPC: B65H20/20
Filed: 1990-10-19
Abstract: PURPOSE:To certainly remove the looseness of a sheet with a simple mechanism by feeding a tractor in positive direction at a normal speed until the top end of a continuous sheet is headed in a determined position exceeding a printing position, then conducting reverse line feed in a determined amount at a low speed, further conducting positive line feed in the same amount at a speed lower than this speed. CONSTITUTION:A continuous sheet 10 is forcedly fed at a normal feed speed by a tractor 11 rotating in positive direction until it is headed in a determined position over a printing part 15. At this time, as the sheet 10 is moved along not a platen 13 side but a guide 17, a looseness 10a is generated in the feed passage of the sheet 10. When it is detected that the top end 10c of the sheet 10 reaches the determined position, the tractor 11 is stopped, and, at the same time, reverse line feed is conducted in a determined amount at a low speed. At this time, the top end 10c of the sheet 10 is lightly held so as to be slipped to the platen 13 rotating in positive direction. The looseness between reversed line feeds of the sheet 10 is gradually reduced, and the sheet is moved on a broken line 10b side. At the point of time where the looseness is considerably reduced, the tractor 11 conducts positive line feed in the same quantity at a further low speed.
