A platelet .alpha.-Al.sub.2 O.sub.3 based ceramic composite consists of Al.sub.2 O.sub.3 powder, promoters and controllers. The composite is prepared by mixing aluminum oxide powder with promoters and controllers. The mixture is shaped and sintered to form an object. In one embodiment of the invention, the promoters are either salts or oxides of alkaline metals and alkaline earth metals. The salts are oxidized during sintering.

Annular guide grooves and rotating ratchet wheels are provided, and feed claws formed in said ratchet wheels moves along said annular guide groove in a circumferential direction. Also, first and second supply conveyers are provided, articles are arranged in the same direction and transferred on these supply conveyers, and sent into said annular guide grooves by supply mechanisms. Said first supply conveyer is arranged to be directed in a direction of a contact line of said annular guide grooves and in the same direction as the moving direction of said feed claws. Said second supply conveyer is arranged to be directed in a direction of a contact line of said annular guide grooves and in the opposite direction to the moving direction of said feed claws. The back portions of said articles sent from said first supply conveyer are pressed by said feed claws, and the front portions thereof are moved toward the advancing direction. The front portions of said articles sent from said second supply conveyer are pressed by said feed claws, and said front portions are moved backward the advancing direction. The articles moved in said guide grooves are transferred on an exhaust conveyer. Therefore, the articles are arranged in a state that the directions of the articles are alternately opposed to each other.

A cooling system for a piston of an internal combustion engine includes a cooling channel (34) designed as an oil passage embedded in the piston and arranged adjacent to a top ring groove, and an oil supply portion (8) that supplies oil to the cooling channel. An amount of oil supplied from the oil supply portion to the cooling channel is made larger when an amount of heat generated in a combustion chamber is large than when the amount of heat generated in the combustion chamber is small.

摘要:
A fuel injection valve coupled to a common rail is provided. When fuel injection is carried out, the fuel pressure in the fuel injection valve pulsates. An interval between a pilot injection and a main injection is set so that the main injection is carried out at a zero gradient timing as a timing when the gradient of the fuel pressure in the fuel injection valve after the pilot injection is approximately equal to zero. Owing to a fuel injection control apparatus and a fuel injection control method for an internal combustion engine that perform the above-mentioned control, the fuel injection amount for the subsequent fuel injection following the preceding fuel injection can be reliably held equal to a normal amount.
