Title: Catalyst deterioration detecting device of internal combustion engine
Inventor: MITSUYA NORITAKE
IPC: F02D41/14
Filed: 1995-10-26
Abstract: PROBLEM TO BE SOLVED: To realize the accurate judgment of deterioration by providing an air-fuel ratio sensor upstream from a three way catalyst and an O2 sensor downstream from it, judging deterioration of the three way catalyst on the basis of the locus length of the output of the O2 sensor during air-fuel ratio feedback control, and interrupting calculation of the locus length when the output of the air-fuel ratio sensor exceeds the set value. SOLUTION: In an electronically-controlled internal combustion engine, an A/F sensor 45 for linearly detecting the air-fuel ratio on the basis of the concentration of oxygen in exhaust gas is provided on an exhaust pipe 34, and a catalytic converter 38 is provided downstream from it. An O2 sensor 46 is provided on an exhaust system downstream from the catalytic converter 38. Deterioration of a three way catalyst is judged by an ECU 70 on the basis of the locus length of the output of the O2 sensor in the air-fuel ratio feedback control based on the output of the A/F sensor 45. When the output absolute value of the A/F sensor 45 exceeds the limit value in which the O2 sensor 46 excessively responds, integration of the data for the catalyst deterioration judgment is interrupted for the specified time, and the erroneous judgment of deterioration is prevented.

Abstract: PURPOSE:To detect the skip stitch at the time of generation by providing an elastic member like contact on a part of a passing path of a needle thread loop engaged to a sword tip in the vicinity of a rotary hook, and detecting the skip stitch, based on an output signal which does not detect an elastic deformation of the elastic member in a prescribed period related to a rotary phase of a rotating hook and determined. CONSTITUTION:In a position of the tip part of an operating part 32c of a plate spring member 32, a U-shaped photointerrupter 36 in a front view is attached to a machine frame 18 through a fitting plate 37, and when the plate spring member 32 is in a reference shape, the operating part 32c is positioned right in the rear side of a detecting part of the middle stage of the photointerrupter 36, but when the plate spring member 32 is in a deformed shape subjected to elastic deformation due to passing of a needle thread loop 41, its operating part 32c moves into the detecting part. This photointerrupter 36 consists of a light emission diode and a phototransistor, and an emitted light emitted from the light emission diode is cut off by the moved operating part 32c, therefore, in a skip stitch detecting period in which the needle thread loop 41 passes through the plate spring member 32, a skip stitch can be detected. In such a way, the skip stitch is corrected automatically.

Title: End face light emitting diode
Inventor: TAKAHASHI SHOGO
IPC: H01L33/14
Filed: 1986-11-24
Abstract: PURPOSE:To easily fabricate an end face light emitting diode enabling the optical output to be extracted efficiently and the horizontal dispersion to be suppressed by forming the light emitting end face of a light emitting region formed on a semiconductor substrate into the shape of a curved surface having a required curvature. CONSTITUTION:The current applied from an electrode 5 is converted to an optical output in an active layer 3. However, since a light emitting end face 31 has a function as a lens because of the difference in refractive index between the atmosphere and an active layer 3, the optical output does not disperse horizontally but is converged and taken out to the exterior. Accordingly, it can be entered also into a small-diameter fiber efficiently. Further, although a striped mesa was formed on the whole and the end face thereof was made into a semicircle, only the end face may be made into a semicircle.

Filed: 1998-10-02
Abstract: PROBLEM TO BE SOLVED: To provide a method for simulating semiconductor element by which such an initial carrier distribution that is improved in convergence can be found through simple calculation without requiring any ambitious program. SOLUTION: When the initial distribution of carriers is calculated for predicting the characteristics of a semiconductor element at the time of performing device simulation, the distribution of the carriers in a steady state is calculated from a charge neutrality condition by setting the temperature of the calculated area at 0 K (ST12), and the temperature in the calculated area is raised by ΔT (ST13). Then a step (ST14) of calculating the distribution of the carriers and the distribution potentials in the calculated area in a steady state when the temperature rises by ΔT by calculating the steady state of an equation for device simulation is repeated until the temperature of the calculated area reaches an aimed value, and the obtained distributions of the carriers and potentials in the steady state are used as the initial distributions of the carriers and potentials used for predicting the characteristics of the semiconductor element through the device simulation.
