摘要： Using a gas detection voltage Vs output from a terminal CU, a determination is made at to whether, after startup of an air-fuel ratio detection apparatus (1), a full-range air-fuel ratio sensor (10) has reached a semi-activated state in which a determination can be made as to whether the air-fuel ratio is on the rich or lean side based on a change in a gas detection signal Vic. After determining that the sensor has reached the semi-activated state, the signal Vic is compared with a threshold to determine whether the air-fuel ratio is on the rich or lean side. In the apparatus (1), the potential difference between an outer pump electrode of a pump cell (14) and a reference electrode of an oxygen concentration measurement cell (24) is obtained via a first differential amplification circuit (53) as the gas detection signal Vic, the signal Vic being highly responsive to a change in air-fuel ratio of exhaust gas.

摘要： A gas sensor diagnostic method includes the steps of counting the reversal number of times that a target air-fuel ratio for an air-fuel mixture to be supplied to an internal combustion engine reverses from a rich side to a lean side or from the lean side to the rich side through a specific air-fuel ratio defined as a boundary of the rich and lean sides; obtaining a detection signal of gas sensor at constant time intervals during a diagnosis period between a timing when the count for the reversal number is started and a timing when the reversal number reaches a predetermined number; calculating a first moderated signal by applying a first moderation calculation to the detection signal, and a second moderated signal by applying a second moderation calculation to the detection signal; calculating a deviation between the first and second moderated signals; and determining whether the gas sensor is in the abnormal state on the basis of the deviation obtained during the diagnosis period.

摘要： A process for producing a single-crystal semiconductor and an apparatus therefor. A single-crystal semiconductor of large diameter and large weight can be lifted with the use of existing equipment not having any substantial change thereto while not influencing the oxygen concentration of single-crystal semiconductor and the temperature of melt and while not unduly raising the temperature of seed crystal. In particular, the relationship (L1, L2, L3) between the allowable temperature difference (ΔT) and the diameter (D) of seed crystal (14) is preset so that the temperature difference between the seed crystal (14) at the time the seed crystal (14) is immersed in the melt and the melt (5) falls within the allowable temperature difference (ΔT) at which dislocations are not introduced into the seed crystal (14). In accordance with the relationship (L1, L2, L3), the allowable temperature difference (ΔT) corresponding to the diameter (D) of seed crystal (14) to be immersed in the melt is determined. Temperature control is conducted so that at the time the seed crystal (14) is immersed in the melt (5) the temperature difference between the seed crystal (14) and the melt (5) falls within the determined allowable temperature difference (ΔT).

摘要： In an activation state of a sensor device, when voltage on the connection points between the sensor device and the sensor control circuit becomes a preset abnormal value, electric cut off is made between the sensor control circuit and the connection point. Then, the delivery of power to the heater is ceased to lower the temperature of the cells to a below of an activation temperature, thereby increasing the internal resistance of the cell. Thereafter, the sensor control circuit supplies to the sensor device a current in a degree not to damage the sensor device, to detect voltages on the connection points at that time. By comparing between the voltages on the respective connection points detected, a content and location of abnormality occurred is identified for the sensor device.

摘要： For minimizing spark energy and improving durability of a spark plug (13) without controlling a time for energizing a primary wiring (L1); the ignition unit (1,2 and 3) for an internal combustion engine is arranged in that actions of a transistor (17) are controlled by an ECU (19) to abruptly interrupt a primary current (i1) such that high voltage for ignition induced to a secondary wiring (L2) is applied on the spark plug (13) for generating spark discharge. For forcibly interrupting spark discharge at a spark discharge duration, the ECU (19) switches the thyristor (21 and 210) ON to supply current to the primary wiring (L1) for forcibly interrupting the spark discharge. By controlling the spark discharge duration to be optimum on a basis of an operating condition of the internal combustion engine, it is possible to restrict generation of multiple discharge and to restrict exhaustion of electrodes of the spark plug (13). It is also possible to realize spark discharge through a simple arrangement of low cost by simply providing a single thyristor (21 and 210).
