Title: Speed change controller for automatic transmission
Inventor: KAMATA SHINYA
IPC: F16H63/40
Filed: 1992-05-08
Abstract: PURPOSE:To prevent a sub-transmission from delay in the completion of speed change by feed-back controlling the sub-transmission so that the gear ratio progress of a main transmission provides the desired gear ratio progress as parameter and feed-forward controlling the sub-transmission when the gear ratio progress of the main transmission is more than a predetermined value and that of the sub-transmission is less than the predetermined value. CONSTITUTION:When the gear ratio progress Gs of a sub-transmission 4 is smaller than the desired gear ratio progress Gst and that or a main transmission 3 is larger than a predetermined value Gm2, whether or not the gear ratio progress Gs of the sub-transmission 4 is smaller than a predetermined value Gs3 is judged. In the case of YES, the speed change progress of the sub- transmission 4 in the hatched region delays excessively. Then, the feed-back control of the sub-transmission 4 is stopped. Oil pressure in a clutch KO for the sub-transmission 4 is set on the basis of the gear ratio progress Gm of the main transmission 3 for forward-controlling oil pressure so that the oil pressure becomes 0, i.e., the speed change is completed in the sub-transmission 4 before the gear ratio progress Gm becomes 100%. Thus, the speed change of the sub-transmission can be smoothly carried out.

Abstract: PURPOSE: To insert a bill with one hand by making a magnetic body and a magnet, provided to a lid body and a frame body, attract each other when the lid body is opened, and then holding the lid body at an opening position. CONSTITUTION: When the lid body 16 is lifted so as to insert the bill into the bill discriminating machine, the magnetic body 21 fitted to the lid body 16 and the magnet 19 fitted to the frame body 12 attract each other and the lid body is held at the opening position. Here, the bill is only inserted into the bill discriminating machine 40. Consequently, the lid body 16 can be held at the opening position, so the bill can be inserted with only one hand. After the inserting operation for the bill ends, the lid body 16 is pushed down with the hand, so that the lid body returns to its closure position. Thus, the operation is done with one hand, so this structure is very convenient. The lid body 16 is held by the magnet 19, so even if the lid body 16 is at, for example, the closure position, the lid body 16 is never broken by the closure of a shutter.  Further, the lid body is only closed upon occasion on a windy day only by being pressed lightly.
