Title: Fuel control device for internal combustion engine
Inventor: FUJIMOTO YUKITO
IPC: F02D41/04
Filed: 1994-10-27
Abstract: PURPOSE: To prevent excessive correction at the time of starting by regulating adhesion control during starting an engine in case that a fuel injection rate is computed based on sum of a direct fuel rate directly intaken in a combustion chamber and the rate of fuel removed from the adhered one to an intake wall surface. CONSTITUTION: An ECU 5 judges whether an engine operation condition is a starting mode or not during running a car. When it is YES, a direct ratio A is determined while searching a TW-A table in which the direct ratio (A) is set larger as a water temperature TW increases. In the starting mode, fuel transfer delay correction is regulated afterward, so that a set value of TW-A table is almost 1.0 for preventing excessive correction in the starting mode. A fuel injection rate is computed based on sum of a direct fuel rate intaken in a fuel chamber without being adhered to a wall surface of an intake pipe 2 and the rate of fuel removed from the adhered one to the intake pipe wall surface.

Title: Method for charged beam exposure
Inventor: GOTO MINEO
IPC: H01L21/027
Filed: 1985-12-24
Abstract: PURPOSE:To prevent exposure-positioning precision from falling due to a glitch, by forming a structure in which exposure by sub-deflection is interrupted only during occurrence of the glitch when digital information on position gives a large glitch to a D/A converter. CONSTITUTION:A pattern is set up for glitch register 43 in accordance with a moving direction of a sample board. When a glitch-generated pattern is detected, a signal is sent to an exposure data-control circuit 45 and then a blanking control signal is turned OFF to interrupt exposure. Then, the blanking control signal is turned ON to restart the exposure. Thus, minute positioning errors of a main deflecting position, which are caused by the glitch occurring in a D/A converter 39 for correcting sample board-motion, can be prevented from occurring. Hence, exposure-positioning precision can be prevented from falling due to the glitch.

Abstract: PURPOSE:To enable a soft seal to be completely peeled from a tape, by blowing air to its inverted part when peeling the seal. CONSTITUTION:A tape T is wound around a tape reel 26 located below a base board 1. The tape is led through a guide roller 25 to the underside of a guide member 22 where the end of the tape is inverted by 180 degrees. A movable member 18 is moved rightward, with a piston 6 and housing 9 of a seal pressing means 3 being moved to the lowered position. Then, the end of the guide member reaches nearly a central portion of the piston 6 located just therebelow.
