IPC: H01L29/10
Filed: 1981-02-24
Abstract: PURPOSE:To contrive the subject structure without increasing the element area wherein the high withstand voltage at p-n junction is available. CONSTITUTION:A p type diffusion region 2 is formed in an n type silicon substrate 1 and the n<+> region in the electrically floating status to augment the withstand voltage is formed near the said p type region 2. With the inverse direction voltage impressed on this p-n diode, the depletion layer is diffused mainly in the layer 1 and almost all the impressed voltage is impressed on the depletion layer which is slightly diffused in the p type region. If the value of the electric field generated in the said depletion layer exceeds the breakdown voltage of silicon, the resultant phenomenon will be the breakdown. In case of the breakdown, the depletion layer arrives at the region 4 making the layer 1 and the n<+> region 4 electrically connect with each other due to the punchthrough to generate the status where the p-n junction inverse vias diode comprizing the regions 2 and 4 is connected to augment the withstand voltage up to the value equaivalent to the breakdown voltage of the said diode.

IPC: C10J3/00
Filed: 1986-02-10
Abstract: PURPOSE:To improve the thermal efficiency in a coal gasification power generation system, by drying an aqueous slurry of a coal which is to be fed into a coal gasification oven by means of a drier wherein the exhaust gas from a gas turbine is utilized and neumatically conveying only a powdered coal to feed into the coal gasification oven. CONSTITUTION:A drier 4 is provided wherein the exhaust gas (a) from a gas turbine 1 is utilized, by means of which an aqueous slurry of a coal (c) is dried to remove the slurry water [to discharge it from the system as steam (d)]. Thus, only a coal (e) is fed into a coal gasification oven 5 by neumatic conveying. The drying of the aqueous slurry of a coal will make the feed into the gasification oven 5 equal to that in a dry feeding system; therefore, the temperature drop in the gasification oven due to the heat of vaporization of the slurry water can be prevented. Consequently, as compared with a system wherein an aqueous slurry of a coal is directly fed, the ash in a coal can be melted well with a lower air ratio to be discharged from the oven, and therefore the thermal efficiency in a coal gasification power generation system can be improved correspondingly.
