Title: Incinerator and management method for incinerator
Inventor: KOBAYASHI SHIZUO
IPC: F23G5/44
Filed: 1997-11-04
Abstract: PROBLEM TO BE SOLVED: To combust the combustibles practically without smoking, and also, suppress the concentration of noxious exhaust gas low, by detecting the temperature of a combustion chamber with a room temperature detection means, and controlling the supply of substance to be combusted to the combustion chamber, based on the detected temperature. SOLUTION: At operation of an incinerator 1, the interior 30 of the combustion chamber 30 of a combustion chamber part 2 is supplied with air and auxiliary fuel, and this is ignited to raise the temperature of the interior of the combustion chamber 30. This temperature is detected with a temperature detector 16, and when the detected temperature gets over the set value, a motor 54 is driven to carry in the combustibles W within a combustibles carrying-in room 5. Hereby, the combustibles W are completely combusted at a high combustion temperature immediately after the start of combustion.  But, in this combustion state, when the detected value of a temperature detector 16 falls under the set value, the motor 54 is stopped to stop the carrying in of the combustibles W, and also the temperature within the combustion room 30 is raised by controlling a blower 14 and an auxiliary fuel pump 15.

Title: Structure of semiconductor package and its manufacturing method
Inventor: TAKEI TOSHIYASU
IPC: H01L21/56
Filed: 1995-12-06
Abstract: PROBLEM TO BE SOLVED: To increase still more density in a semiconductor package, lessen variations of dimensions, and reduce inconveniences of soldering joining due to variations of solder amount. SOLUTION: A mold substrate 2 is resin-molded and a bump 10 for joining it to a printed wiring board is inserted at this time and integrally formed. Namely, as the bump 10 being a joining part to the printed wiring board is integrally molded together with the mold substrate 2, a manufacturing technique is hard to be restricted as compared with a conventional structure fitted by solder joining later on. Downsizing of a diameter of the bump 10 and narrowing of a pitch are possible until limitation of molding. Thereby, density in a semiconductor package 1 can be more increased. Further, quality in solder joining can be enhanced.
