摘要:
A battery voltage detector includes: a voltage detection circuit; a voltage processor; and a power voltage. The voltage detection circuit is configured to detect a cell voltage of a battery cell. The voltage processor is configured to perform analog-to-digital conversion on the cell voltage with a predetermined period to collect cell voltage detection data. The power voltage monitoring circuit is configured to determine whether or not an instantaneous variation of an externally-supplied power voltage occurs, and output an instantaneous variation detection signal indicating a result of detection to the voltage processor. If the voltage processor detects based on the instantaneous variation detection signal that the instantaneous variation of the externally-supplied power voltage occurs, the voltage processor is configured to delete the cell voltage detection data that is the newest.
摘要:
Due to the fact that a regulator engages with an engagement aperture when hydraulic pressure is low due to unexpected decreases in engine rotation frequency during relative turning of a valve timing control device, the valve timing control device re-enters a regulated state. Control and running of regulation or release of relative rotation position of the valve timing control device by a regulator are performed by an external device distinct from the valve timing control device.

A valve timing control device has an input rotational member 3, a case 4, and a cover member 10, which constitute a housing 2. A threaded member 11 such as a bolt is used for being integrated with the cover member 10, the case 4 and the input rotational member 3. A welding section 20 is formed at the bolt 11 to prevent the loosening and detachment of the bolt 11.
摘要:
A hydraulic valve timing adjusting apparatus to be provided in a driving force transmission system for transmitting driving force to a camshaft with a cam for opening and closing an intake valve or an exhaust valve, comprising a housing assembly; a rotor provided so as to be relatively rotatable with respect to the housing assembly; hydraulic chambers formed between the rotor and the housing assembly; a convex member provided in one of the housing assembly and the rotor so as to be slidable therein; a recessed portion provided in the other one of the housing assembly and the rotor so as to be engageable with the convex member; an urging member for urging the convex member toward the recessed portion; and an oil passage which is able to supply oil pressure to the recessed portion; wherein when the oil pressure is supplied to one of the hydraulic chambers, the rotor is relatively rotated with respect to the housing assembly, and when the oil pressure is supplied to the recessed portion, the convex member is slidden in a direction opposite to the recessed portion to release engagement between the convex member and the recessed portion.

A side panel including automobile roof rail structure includes an inner panel formed of front and rear inner panels, an outer panel formed of front and rear outer panels, and an extended member extending rearwards from a rear end portion of the front inner panel. The extended member is provided with upper and lower flanges which are rigidly secured between the rear inner and outer panels so that two closed sections separated by the extended member are formed inside the roof rail.
摘要:
A safety pneumatic tire which can improve running distance under punctured condition comprising an annular resilient reinforcing body having a maximum thickness corresponding to 4 to 9% of the tire maximum width and a JIS hardness of at least 60.degree. in which a ratio of the tire maximum width TW to the rim width RW is 1.0.ltoreq.TW/RW.ltoreq.1.3.
摘要:
A pneumatic radial tire having a ratio of the radius of curvature of inner surface of crown portion to the maximum width of the tire of 1.2/1 to 2.5/1, and provided at the sidewall portion with an annular protection rib projecting over the entire circumference of the tire and having a specifically limited cross-sectional shape is excellent in the puncture resistance at both of the crown portion and the sidewall portion.
摘要:
A region including an engaging hole is given surface treatment such as partial quench hardening by induction hardening for improving surface hardness of the region. The partial quench hardening by induction hardening provides the region with satisfactory mechanical strength or surface hardness enough for resisting deformation of the engaging hole and wear-out of an edge of opening of the engaging hole caused by putting in and out of the lock pin.
