Abstract: <P>PROBLEM TO BE SOLVED: To provide a method for supplying food materials in separated state while preventing the sagging of the material and the formation of horn-like protrusion of the material in the supplying process and provide an apparatus for the supply of the food materials.  <P>SOLUTION: A prescribed amount of a food material G is extruded from a die 11 of a nozzle 1 and a valve 2 in the nozzle 1 is separated from the food material G with an air cylinder 26 before lifting the nozzle and, thereafter, the nozzle 1 is lifted to separate the die 11 from the food material G. Since the valve 2 is separated while the die 11 is brought into contact with the food material G, there is no sagging of the material on the valve 2. The sagging of the material on the die 11 is also prevented because the contact area of the die 11 with the material G is considerably decreased in the separation of the die 11 from the material.  <P>COPYRIGHT: (C)2004,JPO

Abstract: <P>PROBLEM TO BE SOLVED: To efficiently operate an internal combustion engine operated by premixed-compressed-self-igniting a fuel-air mixture.  <P>SOLUTION: A first fuel-air mixture is formed in a combustion chamber. Next, a second fuel-air mixture is formed by ejecting fuel during a compression stroke and ignited to increase pressure in the combustion chamber, thereby the first fuel-air mixture can be compressed-self-ignited. On a piston top surface, a swirling chamber is arranged at a position opposed to an ignition plug. Fuel spray ejected during the compression stroke is introduced to the inside of the swirling chamber through an introducing groove arranged in the piston top surface so as to form the swirl flow of the second fuel/air mixture in the swirling chamber. The second fuel-air mixture can be closed in the swirling chamber, so that the second fuel-air mixture certainly ignited by only ejecting a small amount of fuel can efficiently be formed. As a result, the internal combustion engine operated by premixed-compressed-self-igniting the fuel-air mixture can be operated efficiently.  <P>COPYRIGHT: (C)2004,JPO
