摘要:
Provided is a hybrid silicon wafer made of a wafer comprised primarily of two or more types of concentric single-crystal silicon or polycrystalline silicon prepared by mutually integrating one in a molten state and another in a solid state, and having specific resistances that differ by two orders of magnitude or more. Additionally provided is a method of manufacturing a hybrid silicon wafer, wherein high specific resistance silicon or an ingot comprised primarily of silicon is disposed at a central portion or a decentered position in a crucible, a nugget or powdered silicon having a specific resistance that is lower by two orders of magnitude or more than the ingot is filled in a void part around the ingot in the crucible, the nugget or powdered silicon is selectively melted and integrated with the ingot to form a complex, and a wafer shape is cut out therefrom. The provided hybrid silicon wafer comprises the functions of both a polycrystalline silicon wafer and a single-crystal wafer, or two or more polycrystalline silicon wafers having different functions.

A method of estimating an air-intake amount of an internal combustion engine is provided. The method may comprise detecting a fluid energy amount in an interior of an air-intake passage at first and second points in time while an intake valve is closed from a compression stroke to an exhaust stroke, and calculating a predicted air-intake amount using the values of the fluid energy amounts at the first and second points with reference to an air-intake amount calculation map showing a correlation between the values of the fluid energy amounts at the first and second points and the predicted air-intake amount in the intake stroke, the air-intake amount calculation map being pre-created by finding the values of the fluid energy amounts in the air-intake passage at the first and second points and the air-intake amount, for plural running states of the internal combustion engine.

Provided is a sintered silicon wafer, wherein the ratio [I(220)/I(111) . . . (1)] of intensity of a (220) plane and intensity of a (111) plane measured by X-ray diffraction is 0.5 or more and 0.8 or less, and the ratio [I(311)/I(111) . . . (2)] of intensity of a (311) plane and intensity of a (111) plane is 0.3 or more and 0.5 or less. The provided sintered silicon wafer has a smooth surface in which its surface roughness is equivalent to a single crystal silicon.

An oil pan structure includes a plurality of reinforcement beads of several kinds. An engine utilizes the oil pan, whereby the strength and vibration-rigidity (rigidity against vibration) of the oil pan and the engine are sufficiently enhanced so that a natural frequency of the oil pan and the engine therewith becomes adjustable through a selection as to the numbers, locations, and sizes of the beads.

摘要:
A display panel includes a first halftone dot layer and a second halftone dot layer. The first and the second layers are formed with halftone dots printed at regular intervals in gradation patterns so that brightness gradually changes. The first and the second layers are arranged in parallel to each other yet rotated relative to each other by a predetermined angle measured between directions in which the halftone dots are aligned in the first and the second layers.
