摘要： There are provided a spindle motor 12, an optical head 20, a high-pass filter 31, low-pass filters 32 and 33, an adder 38, and a PLL 39. The spindle motor 12 rotatively drives an optical disk 11. The optical head 20 irradiates a laser beam onto a target track and both tracks adjacent to the target track on the optical disk 11 and detects a return light from each track. The high-pass filter 31 filters a high-frequency component in a signal used for detecting a return light from a target track in the optical head 20. Each of the low-pass filters 32 and 33 filters a low-frequency component in a signal used for detecting a return light from each of the adjacent tracks. The adder 38 operates output signals from the high-pass filter 31, and the low-pass filters 32 and 33. Based on a signal from the adder 38, the PLL 39 generates a reference signal used as a time reference for generating recording signals. An operation by the adder 38 nullifies a cross modulation component.

摘要： The invention provides an electronic control unit for controlling an air/fuel ratio of an engine having a lean NOx catalyst in its exhaust system in order to prevent the decrease of the fuel efficiency without deterioration of the drivability due to a rich operation for reducing the NOx catalyst. The electronic control unit includes: an air/fuel ratio control system for changing the air/fuel ratio to a rich side when the amount of NOx occluded by the lean NOx catalyst exceeds a predetermined value and changing said air/fuel ratio back to a lean side when a first predetermined period has elapsed; a lagging system for lagging ignition timing in synchronization with the air/fuel ratio changing to the rich side by said air/fuel ratio control system; and decrementing system for decreasing the amount of the ignition timing lagged by the lagging system by a predetermined amount when a second predetermined period shorter than said first predetermined period has elapsed after the air/fuel ratio changing to the rich side. According to the invention, it is possible to prevent the decrease of the fuel efficiency without the deterioration of the drivability due to the rich operation to reduce the NOx catalyst because the ignition timing is lagged in synchronization with the air/fuel ratio changing to the rich side and the lagged amount is decremented after a predetermined period has elapsed. In one embodiment, the decrementing system gradually decrements said lagging amount up to a hold value.

摘要： A catalyst for exhaust gas purification has at least one monolith carrier, at least one first catalyst layer having a three-way catalytic activity, provided on the carrier, and a second catalyst layer having a hydrocarbon purification activity, provided on the first catalyst layer. In a gasoline engine automobile provided with the above catalyst for exhaust gas purification in the exhaust gas system, the hydrocarbons present in the exhaust gas can be converted at a high efficiency by introducing secondary air into the exhaust gas in front of the catalyst to make the exhaust gas lean, at the engine start when a large amount of unburnt hydrocarbons are present in the exhaust gas. Further, the engine warm-up property of the automobile can be improved by the heat generated by the catalytic reaction of the hydrocarbons. The catalyst further exhibits a three-way catalytic activity even during the steady state engine operation after warm-up.
