摘要:
A low-pressure delivery pipe provided with intake manifold injectors, a fuel pressure regulator, a high-pressure fuel pump, a high-pressure delivery pipe provided with in-cylinder injectors, and an electromagnetic relief valve are connected in series at the downstream of a low-pressure fuel pump that discharges a fuel within a fuel tank at a prescribed pressure. Since the low-pressure delivery pipe is arranged downstream of the low-pressure fuel pump, the fuel pressure within the low-pressure delivery pipe is lowered upon stop of vehicle operation, in response to stop of the low-pressure fuel pump. The fuel pressure within the high-pressure delivery pipe is also lowered in response to stop of the low-pressure fuel pump, by opening the electromagnetic relief valve upon stop of vehicle operation. Thus, oil tightness of the injectors during the stop of vehicle operation is ensured.

A perimeter for examining a visual field of an eye of a patient, includes: a presentation unit, which presents an examination target at each of various positions around an eye fixation point to which the patient's eye is visually fixed; a position determination unit, which determines at least one of positions of an optic pappila, a central fovea and a macula lutea on a fundus of the patient's eye; and a control unit, which determines a running state of a nerve fiber bundle on the fundus based on the determined position, and which controls the presentation unit to present and move the examination target based on the determined running state of the nerve fiber bundle.

Both evaporated fuel purge and EGR are performed by supplying both an evaporated fuel and an exhaust gas at a position downstream from a throttle valve, of an intake pipe. A controller for controlling a purge flow rate and an EGR flow rate controls an opening degree of a purge control valve and an opening degree of the throttle valve, for example, as an operational state of an engine to compensate for a decrease in the purge flow rate caused by an increase in the EGR flow rate.

A device for driving a self-luminous panel has self-luminous elements arranged at intersecting positions of a plurality of data lines and a plurality of scanning lines and selectively drives the self-luminous elements for luminescence by data line driving means and scanning line scanning means and includes luminescence controlling means for controlling the operation of the data line driving means and the scanning line scanning means. Then, the luminescence controlling means sets a lighting scanning period, during which the self-luminous elements E have forward-biased voltages applied and hence light and luminescence, and a non-lighting scanning period, during which all of the self-luminous elements have reverse-biased voltages applied and hence do not light and luminescence, in one frame period during which the plurality of scanning lines are sequentially scanned by the scanning line scanning means and sets a length of the non-lighting scanning period shorter than a length of one scanning period during which one scanning line is scanned.

In a canister system of seal type, a purge VSV is closed even if a predetermined purge condition is established so as to prevent direct purging of an evaporated fuel within a fuel tank into an intake system of an engine when one of the following conditions is established, that is, (1) a motor pump of an OBD pump module is driven; (2) a switching valve of the OBD pump module is set to ON; and (3) a closing valve is opened.

A perimeter for examining a state of a visual field of a patient's eye includes: a target presenting unit that presents a stimulation target for examination to the eye, a presentation position and a presentation brightness of the target being variable; a first arithmetic unit that obtains a threshold of sensitivity with respect to the presentation brightness at each examination point on a retina corresponding to each presentation position; an input unit that inputs function information at each examination point, the function information at each examination point being objectively obtained by processing a first fundus image of the eye taken before irradiation onto a fundus of the eye and a second fundus image of the eye taken after the irradiation; and a determining unit that determines an initial reference value of the presentation brightness at each presentation position based on the input function information at each examination point.
摘要:
When fuel vapor flows to an intake passage from a canister, the amount of fuel injected to an internal combustion engine is corrected to suppress fluctuation of the air-fuel ratio in the engine due to the fuel vapor. An EGR mechanism variably sets the EGR rate. When the pressure in a fuel tank is greater than or equal to a predetermined value, a tank sealing system releases gas containing fuel vapor from the fuel tank to the canister on condition that fuel vapor is flowing to the intake passage from the canister. A controller controls the EGR mechanism to reduce the EGR rate when gas is released from the fuel tank to the canister. Therefore, combustion is stabilized even if EGR is executed when gas in the fuel tank is released.

The present invention is to provide a drive device and a drive method of a self light emitting display panel in which a reverse bias voltage can be effectively applied to light emitting elements without decreasing the lighting time rate. An electrode which applies an electrical potential to cathodes of EL elements 14 is electrically divided into a plurality of blocks along a scan line, it is possible to select a lighting mode in which a forward voltage is applied to the EL elements 14 via lighting drive transistors 12 and a reverse bias voltage applying mode in which a reverse bias voltage is applied to the light emitting elements, and the reverse bias voltage is applied to the EL elements 14 in units of the block in the reverse bias voltage applying mode.

First and second cylinder groups are connected to a NOx absorbent via a confluent exhaust pipe. The target values of the air-fuel ratio of exhaust gas from the first cylinder group and the second cylinder group are set to a relatively rich value and a relatively lean value, respectively. The target values of the air-fuel ratio of exhaust gas from the first and second cylinder groups are set so that the influent exhaust gas average air-fuel ratio entering the NOx absorbent becomes equal to a relatively slightly rich value. HC in exhaust gas from the first cylinder group and oxygen in exhaust gas from the second cylinder group react in the NOx absorbent to heat the NOx absorbent and cause the NOx absorbent to release SOx. Based on an output signal of an air-fuel ratio sensor disposed downstream of the NOx absorbent, the amounts of fuel to be injected to the first and second cylinder groups are controlled so that the influent exhaust gas average air-fuel ratio becomes equal to its target value.

A snap ring is set to a set portion of a shaft of a rotator from a direction orthogonal to an axial direction of the shaft. The snap ring includes a first arcuate portion and a second arcuate portion facing each other, being elastically deformable in directions away from each other, holding the set portion by elastic deformation restoring force. One ends of the first and second arcuate portions are away from each other to form an insertion portion to insert the set portion. When the snap ring is not used, the first arcuate portion has a same radius of curvature as the second arcuate portion and the set portion, and a center of curvature closer to the second arcuate portion than the first arcuate portion, and the second arcuate portion has a center of curvature closer to the first arcuate portion than the second arcuate portion.
