Patent number: 9130496Abstract: A drive-signal-generating circuit includes: a current-detecting unit to detect a current flowing through a three-phase motor; a calculating unit to calculate d- and q-axis currents based on a detection output of the current detecting unit; a reference-signal-output unit to output a reference signal indicating a first-reference value of the q-axis current for rotating the motor at a target-rotational speed; first- and second-control-signal-output units to output first- and second-control signals corresponding to respective errors between current values of the d- and q-axis currents and a second and the first reference values, respectively; a drive-signal-output unit to output such a drive signal that the d- and q-axis currents reach the second and first reference values, respectively; and an adjusting unit to adjust the detection output so that a ripple of the second-control signal become smaller, after a rotational speed of the motor reaches a predetermined rotational speed corresponding to the target-rotatioType: GrantFiled: August 24, 2012Date of Patent: September 8, 2015Assignee: SEMICONDUCTOR COMPONENTS INDUSTRIES, LLCInventors: Kazumasa Takai, Hiroyuki Morihara

Patent number: 8065113Abstract: The present invention quickly resolves troubles in an analyzer and performs effective external quality control management. An analyzer (2) and a control device (1) are connected by a network (3). Error data and sample data taken from an assay of a quality control substance are transmitted from the control device (1) to the analyzer (2). The analyzer (2) is made to be remotely operable from the control device (1) and when problems arise, repair from the control device (1) is possible. The control device (1) tallies sample data and provides the tally results to a Web page. The analyzer (2) accesses the Web page using a WWW browser, and it can perform external quality control in real time.Type: GrantFiled: September 4, 2009Date of Patent: November 22, 2011Assignee: Sysmex CorporationInventors: Ken'ichi Okuno, Hiroyuki Morihara, Tadayuki Yamaguchi, Tomomi Sugiyama
