IPC: B22D17/12
Filed: 1978-07-27
Abstract: PURPOSE: To let filling of molten metal through runner be smoothly accomplished  by providing a shut valve just before the cavity and letting the same respond to the pressing start of a plunger piston.  
     CONSTITUTION: Molten metal M poured into a sleeve 7 is admitted into a runner 5 through communicating part 6 and its influx into a cavity 4 prevented by a shut valve 10 on the upper stream of the cavity 4. As a plunger piston 8 descends in the sleeve 7 and arrives at molten metal head M 1  while expelling the air between the same and molten metal head M 1 , a cylinder 11 is driven to move the shut valve 10 downward to open the runner 5. Then, the molten metal M begins to flow in the cavity 4 direction by gravity action and is pressure filled into the cavity 4 by further  receiving the pressing of the plunger piston 8 immediately. This method supresses  the occurrence of air inclusion, misrun, etc. and enables the sound casting to be  obtained.

Abstract: PROBLEM TO BE SOLVED: To optimize the input layer of the neural network by evaluating the coefficient of coupling between the input layer and intermediate layer or output layer of the neural network that varies depending upon its learning, and detecting and removing unnecessary data in input data according to the result. SOLUTION: An ordinary learning process is performed by the neural network having the input layer for inputting pieces of data by using a necessary sufficient number of input variables, and the coefficient of coupling between the input layer and intermediate or output layer which varies depending upon the learning is evaluated (S21). Then it is decided whether or not there is unnecessary data according to the evaluation result and the process is ended when there is no unnecessary data (S3). When there is unnecessary data, the input variable is changed (S22) and learning is carried out again (S1); and unnecessary data detected by input evaluation (S21) is deleted. Consequently, the input layer of the neural network can be optimized.

Title: Engine provided with supercharger
Inventor: SAITO MASAAKI
IPC: F02D23/00
Filed: 1999-03-31
Abstract: PROBLEM TO BE SOLVED: To improve responsiveness and trade offs of smoke generation, while an engine is being accelerated by changing the supercharging efficiency of a supercharger, based on the excess air rate of intake air to fuel injection quantity. SOLUTION: A slightly high excess air ratio λ1 is set relative to critical excess air ratio λ0 that generates smoke in an exhaust gas. When an engine is accelerated, as an excess air ratio l, that is determined from fuel injection quantity and intake air quantity, is less than excess air ratio λ1 as shown in the area B and approaches critical excess air rate λ0, the supercharging efficiency of the supercharger arranged in an intake air pipe is controlled to be improved to increase intake air quantity, preventing the generation of smoke in combustion gas. In such a control, fuel injection quantity is not limited so that the output responsiveness of the engine in acceleration is not deteriorated.
