Inventor: BERGER JOACHIM
IPC: G01N27/26
Filed: 1999-09-22
Abstract: PROBLEM TO BE SOLVED: To determine a function of a NOx catalyst on the basis of a NOx sensor signal so as to improve the reliability of determination by regulating exhaust gas so that it includes much NOx in the first process than in the second process while includes a reducing agent in the second process. SOLUTION: In a time(t)=O when a NOx storage catalyst 2 is empty, an internal combustion engine 1 is operated with a lean mixture in the first process, and NOx discharged in this process is stored in the storage catalyst 2. When the storage catalyst 2a is fully charged, that is, when a NOx sensor signal reaches an upper limit threshold value UL, the first process is switched to the second process, and the regeneration of the storage catalyst 2 is carried out. In this regeneration carried out by a rich engine operation with a λvalue less than 1 in the second process, unburnt HC and CO are discharged so as to be used as a reducing agent reacting with NOx and water, CO2, and N2 are generated, so that a NOx content can be lowered.

Title: Intermittent feeder of board material
Inventor: KUROKI MICHIO
IPC: B65H5/00
Filed: 1984-12-20
Abstract: PURPOSE:To reduce the number of parts and manpower while to simplify the structure by fixing the inner ring of oneway clutch to a reciprocal/rotatable shaft while forming the outer ring into a tubular feeding face contactable directly with a board material thereby eliminating a feeding tube. CONSTITUTION:Upon continuous rotation of an input disc 11 in C-direction, an output shaft 16 is reciprocated/rotated through an interlocking bar 13 and a reciprocal bar 30. Since an inner ring 22 of oneway clutch 20 is fixed to the output shaft, only the rotation of the output shaft 16 in A-direction is transmitted to the outer ring 21. In other word, the outer ring 21 will rotate continually in A-direction and since the outercircumferential face of the outer ring 21 is formed into a tubular feeding face contactable directly with a board material S, said material S is fed intermittently. Consequently, independent feeding tube can be eliminated to exhibit the function of feeding tube through the outer ring of one way clutch resulting in reduction of the number of parts and manpower and simplification of structure.

Title: Defect inspecting apparatus
Inventor: KITAZUMI KAZUNORI
IPC: G01N21/94
Filed: 1989-10-17
Abstract: PURPOSE:To select only the defect which will cause trouble out of the detected defects by detecting the defects in an object to be inspected based on the change in physical quantity such as light, converting the electric signal corresponding to the physical quantity into a frequency, and counting the number of pulse in a pulse train. CONSTITUTION:An object to be inspected is scanned with a detecting means 14. The defects of the object to be inspected are detected based on the change in physical quantity such as light. The electric signal corresponding to the change in physical quantity is outputted into an electric-signal/frequency converting means 20. The mean 20 converts the signal into the pulse train having the frequency which is proportional to the magnitude of the electric signal. The number of the pulses in the converted pulse train corresponds to the product of the light of the defect region and the quantity of the defects corresponding to the physical quantity detected with the means 14. Therefore, the degree of the defect is computed by simulating the count signal from a counting means 22 as the area of the defect. In a judging means 24, the count of the count signal is compared with a preset value. The preset value is determined in correspondence with the conditions such as the lower limit value which might bring about trouble and the allowable upper limit. Thus, with which condition the count signal value agree is judged. Only the defect which will cause a trouble is selected out of the detected defects.
