Filed: 1999-03-24
Abstract: PROBLEM TO BE SOLVED: To realize power demand prediction which is improved in precision by determining the best prediction model according to the increase or decrease of an output error calculated by using output data from the prediction model and actual data. SOLUTION: Learning data of past several years up to a recent year and near future input data are generated (S1) to learn a prediction model for a power demand (S2). Only data limited to the near future are inputted to output data from the prediction model, and the error between these output data and power demand data is calculated as an evaluation index (S3). When the evaluation index corresponding to the input data is referred to and pound improved, the prediction model is saved (S5). When the evaluation index becomes worse, the learned prediction model is discarded, learning conditions of the prediction model are changed to carry out learning agent, and similar operations are repeated to decide whether the learning may be finished (S6). When the evaluation index decreases below a predetermined output error, the learning is finished.

Abstract: PURPOSE:To make it possible to implement high integration density and high speed, by selectively etching and removing a part of an epitaxial layer, and controlling the thickness of the epitaxial layer to a buried layer. CONSTITUTION:An SiO2 film, which is patterned, e.g., in a specified region, is used as a mask, and Sb (antimony) is diffused in a P-type Si substrate 11. Thus an N<+> layer 12 is formed. With the SiO2 film as a mask by the similar way, B (boron) is implanted, and a P-type diffused layer 13 is formed. After the mask SiO2 film is removed, P-type or N-type Si is grown. The N<+> layer 12 and the P-type layer 13 are made to be buried layers. Then, e.g., with a patterned SiO2 film 15 as a mask, an epitaxial layer 14 is etched away with, e.g., KOH solution. After the SiO2 film is removed, electronic elements are formed in the order of, e.g., an element isolating step, a trench capacitor forming step, formation of gate polysilicon and formation of emitter polysilicon Al wiring. Thus a capacitor, a bipolar transistor and a MOS transistor can be formed on the same substrate. In this way, the performance of each element is not deteriorated, and high integration density and high speed can be implemented.

IPC: G01F1/68
Filed: 1996-04-02
Abstract: PROBLEM TO BE SOLVED: To suppress lowering of flow velocity at a heating resistor part caused by drift and air turbulence and stabilize a flow rate so as to reduce output noise by forming an internal wall of a main air passage near an inlet of an auxiliary air passage, into shape with a vertically stepped face in a direction of main air flow in the main air passage. SOLUTION: A main air passage 1 and an auxiliary air passage 2 provided with a heating resistor 4 and a thermosensitive resistor 5 are formed in a body 3. The heating resistor 4 and the thermosensitive resistor 5 are electrically connected to a module 7. A plane part 8 with vertical step difference to main flow is provided from the internal wall of the body near the inlet of the auxiliary air passage 2, and generated dynamic pressure heightens pressure in the surroundings so as to intensify pressure at the inlet part of the auxiliary air passage 2. On the other hand, since flow is intercepted by the plane part 8, flow velocity in a block without an obstruction including the upper reaches of the outlet of the auxiliary air passage 2 is increased.  The pressure difference between the inlet and outlet of the auxiliary air passage 2 is thereby increased, so that the flow velocity of the heating resistor part is increased, and output noise is reduced.
