Title: Exhaust emission control device and exhaust emission control method
Inventor: ITO KAZUHIRO
IPC: B60L50/16
Filed: 2001-10-10
Abstract: PROBLEM TO BE SOLVED: To stably purity carbon-contained suspended particulates in exhaust gas. SOLUTION: A purifying catalyst is provided in an exhaust pipe of a diesel engine mounted on a hybrid vehicle in order to collect the carbon-contained suspended particulates in the exhaust gas and oxidize collected particles with the usage of a catalyst function. The carbon-contained suspended particulates are sometimes accumulated on the purifying catalyst depending on an operation condition of the engine. When the particulates are accumulated, concentration of oxygen in the exhaust gas flowing into the purifying catalyst is increased. Thus, oxidization of the particulates accumulated on the purifying catalyst can be accelerated. Thereby, particulates in a large amount are prevented from being accumulated on the purifying catalyst, and the catalyst function is prevented from being obstructed.  Accordingly, the carbon-contained suspended particulates in the exhaust gas can be stably purified.

Inventor: NOMURA KAZUHITO
IPC: H01L21/52
Filed: 2001-11-16
Abstract: PROBLEM TO BE SOLVED: To provide a connecting method which reduces occurrence of a void in a center, immediately under the heating region of a semiconductor chip, in a method for manufacturing a semiconductor device. SOLUTION: When soldering 5, before being heated and melted, is arranged at a position avoiding the center of the heating region 6 as shown in Fig. (a), the void will not exists in a region corresponding to the center of the heating region 6 of the semiconductor chip 2, as shown in Fig. (b). Even if voids 7 generate, the generated position of it is only a region corresponding to the position, avoiding the center of the heating region 6 of the semiconductor chip 2. Thus, even if the heating region 6 generates heat, when the semiconductor chip 2 is operated, the center of the heating region 6 of the semiconductor chip 2 is prevented from being heated to a high temperature, due to the existence of the void 7. Thus, at the center of the heating region 6 of the semiconductor chip 2, heat is radiated equally to eliminate a locally high-temperature part.  Thus, the deterioration in the characteristics and deterioration of breaking strength are prevented, to secure a long service life.
