Title: Combustion chamber of internal combustion engine
Inventor: YANAGISAWA NAOKI
IPC: F02B23/06
Filed: 1987-12-23
Abstract: PURPOSE:To make it possible to widely diffuse injected fuel in a circumferential direction and deeply in a combustion chamber by supplying fuel through a fuel injection nozzle having plural nozzle holes toward the downstream sides of air swirling flows introduced into the combustion chamber at high, middle and low levels. CONSTITUTION:When a piston 1 moves to the end of a compression stroke or near a top dead center, a subnozzle hole 10 is first released to supply atomized fuel into a subcombustion chamber 4, and then, when a needle valve lift value of a fuel injection nozzle 7 at the time of a light engine loading is exceeded, nozzle holes 8-11 as well as the subnozzle hole 10 are released to supply the atomized fuel into a main combustion chamber 3 too. The atomized fuels f1, f3, f4 injected through the nozzle holes 8, 10, 11 evaporate as they are made to flow downstream and diffuse widely by swirls Sc, Sd. On the other hand, the atomized fuel f2 injected through a nozzle hole 9 diffuses and evaporates as it is made to flow by swirl Sd from the upper side of the main combustion chamber 3 toward its bottom. Thus, since an air-fuel mixture is diffused and distributed almost uniformly in the main combustion chamber 3, its relatively quick combustion can be made by a flame propagated through a communicating port 5.

Since the data quantity is less by the 420 component coding, even when the residual capacity of the memory card 5 is less, the data are recorded on the memory card 5.

Title: Neural network simulator
Inventor: INAZUMI MITSUHIRO
IPC: G06N3/10
Filed: 1988-12-23
Abstract: PURPOSE:To perform a product sum operation at a high speed by writing the product sum information into the forward and backward data decoding information memory parts respectively and translating the arithmetic address via the forward data decoding information memory part. CONSTITUTION:In a direct address mode the product sum information 37 and 38 are written into a forward data decoding information part and a backward data decoding information memory part respectively. Then the setting operation of a mode memory part is changed to a forward indirect address mode in a forward mode. Therefore the linear address received from an arithmetic executing part 23 is translated into an optional address of a complicated flow with storage of the forward data decoding information. As a result, the frequency of memory accesses needed for calculation of complicated product sum arithmetic processes can be substantially reduced down to 1/2. Then the computing speed is increased.
