摘要： In the ignition system of the internal combustion engine, a preignition control circuit is further provided. The preignition control circuit includes a high voltage generator which supplies a high voltage to the spark plug to produce a preignition spark between the electrodes of the spark plug. The preignition spark is timed to appear as the engine nearly concludes its suction stroke so that radicals are produced from the air-fuel mixture around the electrodes thereby to ensure reliable ignition and complete burning of the air-fuel mixture.

摘要： A method for selectively diffusing impurities such as zinc into the substrate of a compound semiconductor such as gallium arsenide (GaAs). The method makes use of a diffusion mask in such a manner that the thickness of the oxygen-containing layer at the interface between the diffusion mask and the semiconductor substrate is less than 20.ANG. so that the abnormal transverse diffusion that would otherwise occur at the interface in the vicinity of the opening of the diffusion mask on the semiconductor surface is suppressed. The result is an increased accuracy in the diffusion pattern of the impurities.

With this structure, an effective gate length is defined by the thickness of the second semiconductor layer. Therefore, when the thickness of the second semiconductor layer is precisely controlled, a gate length can easily be shortened, and a current density can be increased when compared with a conventional device.

摘要： An object of the present invention is to efficiently extract proteoglycan from aquatic animal tissues. The method of the present invention is a method for extracting proteoglycan from fish cartilage, comprising the step of (A) heating small pieces of frozen fish cartilage in water. This method of the present invention enables easy extraction of proteoglycan from fish cartilage with very high efficiency. In particular, the method of the present invention enables extraction of high-molecular-weight proteoglycan. Further, since in the method of the present invention, extraction is performed using only water, it ensures safety in the extraction and safety of the resulting proteoglycan product, compared with hitherto known extraction methods using organic solvents or acids/alkali. Furthermore, the cumbersome step of removing organic solvents is not necessary in the method of the present invention.
