Title: Controller of vehicular automatic transmission with supercharger
Inventor: TABATA ATSUSHI
IPC: B60W10/12
Filed: 1995-11-28
Abstract: PROBLEM TO BE SOLVED: To prevent the shock of engagement of a hydraulic frictional engagement device regardless of the operating condition of a supercharger. SOLUTION: If an abnormally supercharged state recognition means 186 recognizes an abnormally supercharged state caused by a supercharger, a control stop means 188 stops the control of a hydraulic frictional engagement device (lock-up clutch 24, clutch and brake of automatic transmission 14, and differential limiting clutch CT) which is based on output torque TEX estimated by an output torque estimation means 176.

IPC: B41J2/05
Filed: 1996-11-21
Abstract: PROBLEM TO BE SOLVED: To prevent leakage of ink or entry of air bubbles into an ink passage when an ink cartridge is attached to/detached from a printer. SOLUTION: Before a cartridge 20 is inserted to a printer, a ball 102 is pressed to a slit 110 of an elastic diaphragm 104 at a front end of a fluid discharge port 28, and therefore the discharge port is tightly sealed to liquid. A hole 168 at a front end part of a hollow needle 162 in a fluid entrance 42 at the side of the printer where the ink flows is shut by an upper part of a sliding collar part 170, and an ink passage at the side of the printer is also sealed to liquid. When the cartridge 20 is inserted further, the front end of the discharge port presses an upper face of the sliding collar part downward, thereby lowering the collar part. As a result, the hollow needle penetrates the slit of the diaphragm, whereby the ball is pressed up and the ink in the cartridge is coupled to the printer via the hole at the front end part of the hollow needle.
