20120103084 | AIR FLOW MEASURING DEVICE - An air flow measuring device includes a passage forming housing, a sensor housing, and a sensor part. An inner wall surface of the passage forming housing defines a measured passage. The passage forming housing includes a sensor attaching part. Measured air flows through the measured passage. The sensor housing is attached to the sensor attaching part. The sensor part is disposed on the sensor housing and measures a flow rate of the measured air flowing through the passage. The passage forming housing includes a guiding device for guiding the measured air, which flows along the inner wall surface of the passage forming housing on an upstream side of the sensor attaching part in a measured air flow direction, further toward a center of the passage than the inner wall surface of the passage forming housing on a downstream side of the sensor attaching part in the flow direction. | 05-03-2012 |
20120240668 | AIR FLOW MEASUREMENT DEVICE - An air flow measurement device arranged in an intake passage includes a bypass passage having an inlet from which a part of a main flow of an intake air is introduced, and an outlet from which the introduced intake air flows out. A sensor is located in the bypass passage to generate an electrical signal, and the bypass passage communicates with the intake passage through a hole portion. The outlet is open toward a downstream side of the intake passage in a flow direction of the main flow of the intake air. The hole portion is located within an outlet projected area that is provided by projecting an open area of the outlet in straight and toward upstream in the flow direction of the main flow on a projection surface perpendicular to the flow direction of the main flow. | 09-27-2012 |
20130028288 | AIR FLOW MEASURING DEVICE - An air flow measuring device includes a fitted part, a housing, a flow sensor, and a temperature sensor component. A projection shape of the fitted part onto an imaginary plane is a first circle. On the imaginary plane, a first point and a second point are located on the first circle or inward of the first circle, and a third point is located inward of the first circle. A diameter of an imaginary circle passing through the first, second, and third points is larger than a diameter of the first circle. The first, second, and third points have such a positional relationship that, when at least one of the first and second points comes into contact with an inner peripheral surface of an attachment hole at time of insertion of the housing into a duct, the third point is away from the inner peripheral surface of the attachment hole. | 01-31-2013 |
20130055800 | AIR FLOW MEASURING DEVICE - An air flow measuring device includes a housing, a sensor, and a throttle that is provided on an outer wall surface of the housing. The throttle merges together a bypass-passing flow and an outside-passing flow, and guides the merged flow toward the downstream side with the merged flow narrowed. The throttle includes two raised portions and a cover that bridges between the two raised portions and is opposed to the outer wall surface of the housing. The cover includes an inner surface exposed to the throttle, and an outer surface exposed to outside of the throttle. A peripheral border of the cover includes an upstream edge which defines the outer surface on the upstream side. At least a region of the outer surface including the upstream edge is swollen more outwardly in a shape of a projecting curved surface further on the downstream side. | 03-07-2013 |
20140299081 | VALVE TIMING CONTROL APPARATUS - A valve timing control apparatus includes a temperature sensing member which expands at a main lock phase when a temperature of an engine is higher than or equal to a predetermined temperature so as to prohibit a main lock component from moving out of a main lock hole to a guide slot. The temperature sensing member shrinks at the main lock phase when the temperature of the engine is lower than the predetermined temperature so as to allow the main lock component to move out of the main lock hole toward the guide slot. | 10-09-2014 |
20150096365 | MANUFACTURING METHOD FOR RESIN HOLLOW MEMBER AND AIRFLOW MEASURING DEVICE HAVING THE RESIN HOLLOW MEMBER - A pair of half hollow members are mated to each other at mating surfaces to form a resin filling space between the mating surfaces. The resin filling space is charged with melting resin, and the melting resin is solidified. Each of the mating surface has a groove. The groove has a bottom surface in which a hole opens. The groove and the hole form the resin filling space between the mating surfaces when the half hollow members are mated to each other. A wall surface of the groove and an inner circumferential periphery of the hole are equipped with a melting projection, which are configured to be melted with heat of the melting resin and to be solidified with the melting resin. | 04-09-2015 |
20150355009 | AIRFLOW-RATE DETECTING DEVICE CAPABLE OF DETECTING HUMIDITY - An airflow-rate detecting device capable of detecting humidity has a housing, a flow rate sensor, a humidity sensor, a humidity sensor case, and a dust separating portion. The housing therein defines a bypass passage into which a part of air flowing in a duct flows. The flow rate sensor is disposed in the bypass passage. The humidity sensor detects a humidity of air flowing in the duct at an outside of the housing. The humidity sensor case houses the humidity sensor and therein defines an interior space into which a part of air flowing in the duct flows as a target air of which humidity is detected by the humidity sensor. The dust separating portion removes dust from the target air before the target air flows into the interior space. | 12-10-2015 |
20150377671 | AIR FLOW METER - An air flow meter has a housing, a flow rate sensor, and a physical-quantity measuring sensor. The housing therein defines a bypass passage into which a part of air flowing in a duct flows. The flow rate sensor is disposed in the bypass passage. The physical-quantity measuring sensor measures a physical quantity of air flowing in the duct and is disposed separately from the flow rate sensor. The housing has a recessed portion that is recessed from an inner wall surface of the bypass passage and that has a blind-passage shape. The physical-quantity measuring sensor is disposed in the recessed portion. | 12-31-2015 |
