摘要： An oil pan for an internal combustion engine having an engine lubrication system. The oil pan comprises a shallow bottom section and a sump section. A guide plate is secured at an inner surface to which a crankshaft splashes lubrication oil carried into the shallow bottom section. The guide plate having an inclined and a guide parts extends generally along the axis of the crankshaft and extends generally parallel with a horizontal plane. The inclined part which gradually becomes high in level in the direction toward the sump is continuously connected to the inclined part to be formed in a generally arcuate shape. Therefore, the splashed oil at the inner surface cannot over the guide plate, and the oil is positively returned into the sump section by the guide plate. Accordingly, lubrication in this engine is smoothly carried out without causing a lack of the oil in the sump section.

摘要： An internal combustion engine is equipped with a crankcase ventilation system in which fresh air flows through a crankcase. The cylinder block of the engine is formed with a fresh air suction port whose one end is opened to the chamber of a crankcase in order to establish communication between a rocker cover chamber and the crankcase chamber. The one end of the fresh air suction port is located in the vicinity of the peripheral surface of a counterweight of a crankshaft. The rotation of the counterweight develops vacuum thereby to suck fresh air from the rocker cover chamber through the fresh air suction port into the crankcase chamber, thereby effecting ventilation in the crankcase.

摘要： In the event of an accident encountered by a vehicle, an emergency signal is automatically transmitted for asking a rescue. An acceleration of the vehicle in the inclination of the vehicle and the presence or absence of water within the vehicle are detected, and an emergency signal is transmitted whenever one of these items indicates the occurrence of an abnormality. A plurality of antennae are disposed at mutually different locations on the vehicle, and are selectively used for transmission of an emergency signal. The antenna selected is periodically and sequentially changed.

摘要： A digital signal receiving apparatus includes a detection-judging portion having a first smoothing filter generating a first smoothed signal by smoothing an auto-correlation signal and judging a possible presence of a desired signal when a signal level of the first smoothed signal is greater than a reference level and an absence of the desired signal when being smaller than the reference level. The smoothing filter includes a limiting portion limiting a fluctuation width of the first smoothed signal; and an adjusting portion configured to adjust the fluctuation width of the first smoothed signal limited by the limiting portion to be reduced while an elapsing time after the detection-judging means judges the possible presence of the desired signal is increasing.

摘要： A control method for a door lock device performs an unlocking operation of a lock mechanism of a vehicle door by energizing and actuating an actuator in response to an unlocking command from a vehicle user. The method has: a first time period (T1) for energizing the actuator in accordance with the unlocking command by the user; a second time period (T2) for returning an operation portion provided on a vehicle from an operated position to a normal position; and a third time period (T3) during which the actuator starts the unlocking operation and complete the unlocking of the lock mechanism. The first time period is determined to be equal to or longer than a sum of the second time period and the third time period.

摘要： In a human body detector, a wave-detection circuit for detecting waves of a resonance voltage is connected to a sensor resonance circuit that varies a constant frequency voltage in accordance with a change in the capacitance of a sensor electrode. The wave-detection circuit is connected to a differentiator that acquires a changing rate by differentiating the wave-detection voltage with respect to time, and allows a voltage to pass if the changing rate of the voltage is greater than or equal to a predetermined value. The differentiator is connected to a high-pass filter that allows passage of a voltage whose changing rate is greater than or equal to a second predetermined value. The high-pass filter is connected to a comparator whose non-inversion input terminal is connected to a power source that applies thereto a reference voltage.

摘要： An optical attenuator which provides almost the same degree of attenuation even when the difference in wavelength of two different kinds of input optical signals is small. Another optical attenuator is provided with a dopant concentration in a technically realizable range which increases the difference in optical attenuation of two different kinds of input optical signals. Almost the same degree of attenuation may be obtained even when the difference between wavelengths is small by canceling the wavelength dependency of attenuation of the dopant by raising the refractive index of an axially central portion of the core as compared to that of the peripheral portion of the core and by taking into account the type and area of the dopant and the ratio of the difference &Dgr;2 between the refractive indexes of the cladding and the axial portion of the core and the difference &Dgr;1 between the refractive index of the cladding and the refractive index of the peripheral portion, i.e., &Dgr;1/&Dgr;2. On the other hand, the difference of attenuation is increased while suppressing the concentration of dopant to the realizable range.
