摘要： An oil pump having an inner rotor with of external teeth; an outer rotor that is eccentrically provided and has internal teeth that mesh with the inner rotor external teeth, and an oil pump body that accommodates the outer and inner rotors. By rotationally driving the inner rotor to increase and decrease a space between the internal and the external teeth, an intake stroke suctions hydraulic oil from the oil pump body and a discharge stroke discharges the suctioned hydraulic oil to a discharge port formed in the oil pump body. Between the intake and discharge strokes, a confinement stroke cuts off the suctioned hydraulic oil and confines the suctioned hydraulic oil in the space, and a compression stroke reduces the space and compresses the confined hydraulic oil. Further, an interval is set between a finish end portion of the intake port of the oil pump body and a start end portion of the discharge port such that a rotation angle of the inner rotor during the compression stroke is 21 to 27 degrees.

摘要： A circuit board is equipped with soldering lands for a hall element and visual inspection marks printed at a vicinity of the soldering lands. The visual inspection marks include a pair of slender marks arranged so as to sandwich the two soldering lands to which two terminal pins protruding from an edge of the hall element are soldered. When the hall element is mounted at a correct position, tips of the two terminal pins arranged in a row are positioned on a straight line that connects the pair of slender marks. In addition, a third slender mark is printed at a middle position between the pair of slender marks and between the two soldering lands.
