Title: Anomaly detection system for particulate filter
Inventor: KOBAYASHI MASAAKI
IPC: F01N3/02
Filed: 2000-01-26
Abstract: PROBLEM TO BE SOLVED: To detect an anomaly in a particulate filter with ease and accuracy. SOLUTION: This particulate filter(DPF) 43 is interposed in an exhaust passage 3 for an engine 1, and an EGR valve 23 for controlling the quantity of EGR gas is interposed in an EGR passage 33 for the engine. An electronic control unit(ECU) 30 for the engine provides feedback control on the opening of the EGR valve so that the intake air quantity that an airflow meter 25 detects becomes a target intake air quantity ser according to the engine operating state. If the EGR valve opening detected during the EGR valve opening feedback control is found greater than the reference EGR valve opening that is EGR valve opening during EGR valve opening feedback control under an engine operating state with the DPF being in the normal state, the ECU determines that the DPF is in a broken state.

Title: Film forming equipment
Inventor: TAKEUCHI HIROAKI
IPC: H01L31/04
Filed: 2000-02-17
Abstract: PROBLEM TO BE SOLVED: To provide film forming equipment which can simultaneously achieve the uniformization of a film formed on a substrate having a large area and an increase in film forming speed by suppressing the temperature rise of the substrate caused by a heated catalyst. SOLUTION: A thin film is formed on a partial surface of the substrate 8 by only supplying a gas containing a chemical species produced by bringing a gaseous starting material into contact with a catalyst 6 to the partial surface of the substrate 8 through a gas supplying pipe 3. The gas supplied to the partial surface of the substrate 8 is quickly discharged from the surface of the substrate 8 through a pair of gas discharging pipes 4 laid closely to the pipe 3. Consequently, the conductance of the gas flow can be increased and, accordingly, the gas can be supplied to the surface of the substrate 8 at a large flow rate. Since the substrate 8 is horizontally moved relatively to the pipes 3 and 4 by means of a moving means 10, a uniform thin film is formed on the whole surface of the substrate 8.
