Abstract: PURPOSE:To easily diagnose abnormality of an injector in a short time by comparing a time at which an air-fuel ratio sensor has values exceeding the upper and lower limit values with a specified time set shorter than the time converged to a value corresponding to a theoretical air-fuel ratio by a coarse items. CONSTITUTION:An output signal of an air-fuel ratio sensor B arranged downstream three-way catalyst of an exhaust system is inputted to a calculation means C. Proportional control is carried out at the time of reversing the output of the air-fuel ratio sensor B, and control is carried out at the other time to compute rough control items of air-fuel ratio compensation. Integral control and proportional control are carried out from the output of the air-fuel ratio sensor B so as to calculate the storage term by means of a computation means D, and thereby a fuel injection quantity is controlled based on the coarse storage items. The continuous time of rich or lean condition of exhaust gas is measured by a measuring means F based on the output of the air-fuel ratio sensor B.

Title: Air conditioner
Inventor: KUNIMOTO KEIJIROU
IPC: F24F11/02
Filed: 1981-11-19
Abstract: PURPOSE:To improve the comfortable property thereof and save the energy therefor by a constitution wherein the periodical blow-off range of an air flow direction changing device is changed in accordance with a room temperature. CONSTITUTION:When room cooling is started, a low-speed motor 11 is operated to move vanes 8 into up-and-down directions and change the direction of air flow. At this time, a temperature sensitive section 18 detects the room temperature. When the room temperature is high, a temperature sensitive liquid elongates an operating section 19 to bring a swinging shaft 22 to a place near the center of a motor shaft 12 and a slide pin B17. Accordingly, the swinging range of a swinging plate 28, which is caused by the rotation of a slide pin A14, is transmitted with the same range of the slide pin B17 and thereby extending the air flow changing range of the vanes 8 into a wide range. When the room temperature is reduced, the swinging shaft 22 is shifted to the side of the slide pin B17 to narrow the air flow direction changing range and flow the air in parallel with a ceiling. According to such constitution, the environmental comfortableness is improved and the energy for the device may be saved.

Title: Method for adjusting operation point of diode in diode circuit network by voltage application
Inventor: BERGER WERNER
IPC: H04B10/60
Filed: 1999-07-01
Abstract: PROBLEM TO BE SOLVED: To eliminate an inductor for decoupling a voltage source from a diode by providing a controller for keeping the diode voltage constant. SOLUTION: The higher harmonic component of a signal flows to a terminal 3 from a terminal 2 through two parallel branches. The respective branches are formed of a series circuit containing capacitors C and two diodes D (semiconductor diodes). The diodes in the two branches have opposite polarities. The capacitors C are directly and mutually connected. In such a case, voltage V1 is positive and it is designed so that it becomes equal to voltage required for the respective diodes D in the upper branches for setting a desired operation point. The effective steepness of a diode characteristics is decided by the selection of the operation point. Resistors R2 and R3 are designed so that the voltage of 2×V1 is supplied to a mutual connection point 4 and the two diodes D are connected in series.  In general, the resistors R2 and R3 are selected so that the voltage of k×V1 is supplied to the mutual connection point 4.
