Title: Method for forming optical element
Inventor: KURIHARA NORIKO
IPC: C03B11/00
Filed: 1988-09-19
Abstract: PURPOSE:To appropriately obtain a glass optical element by forming the element in an oxygen atmosphere at a specified oxygen partial pressure at the time of press-forming the glass material using a forming die. CONSTITUTION:The glass material is press-formed in an oxygen atmosphere at 1-100 Pa oxygen partial pressure. An inert gas such as nitrogen can be added to the press-forming atmosphere in addition to oxygen. A forming die coated with an a-C:H film at the part in contact with glass through a diamond film is preferably used as the forming die, since the die is not oxidized in press forming. The sintered hard alloy and ceramic having excellent specular property and heat resistance can be exemplified as the base material for the forming die. When the oxygen partial pressure and the forming die are used, the glass is not fused to the die especially at high temp., the die is hardly oxidized, and lead is not deposited. Furthermore, the surface precision of the formed optical element is not deteriorated even after repeated forming.

Filed: 1994-08-31
Abstract: PURPOSE: To prevent malfunction of starting due to adhesion of fuel to an ignition plug particularly in an extremely low temperature in an engine wherein simultaneous injection is performed at the time of starting until completion of cylinder determination. CONSTITUTION: Cylinder is determined based on an SGC signal in evenry 360 degrees of a crank angle and an SGT signal in evenry 180 degrees of the crank angle. After starting, sequential injection is performed in an intake process in every cylinder with a specified order. At the time of starting, the sequential injection in the intake process is stopped, and the sequential injection is performed in processes other than the intake process in every cylinder, in a three-divided form. At the starting time, simultaneous injection is performed in all cylinders until cylinder determination is completed. In the case of a low temperature where, for instance, an engine water temperature does not reach a minus 15 deg.C, fuel is cut so as to prevent malfunction in starting due to halation of a plug.
