Title: Photodetector and light detecting method
Inventor: TAKEYAMA TOMOAKI
IPC: H01L31/09
Filed: 2008-02-19
Abstract: <P>PROBLEM TO BE SOLVED: To always detect light having feeble intensity with high accuracy by accurately monitoring the light and compensating the dark current without rise of cost.  <P>SOLUTION: An inverse voltage applied to a photodiode 11 is changed and difference in output currents of the photodiode 11 generated by changing the inverse voltage is detected. This current difference is converted to a dark current value with reference to correspondence between current difference previously obtained by using dependence on inverse voltage of dark current and this dark current and an optical current value is obtained by subtracting the dark current from an output current of the photodiode 11.  <P>COPYRIGHT: (C)2009,JPO&INPIT

Abstract: <P>PROBLEM TO BE SOLVED: To provide a variable valve gear capable of automatically eliminating deviation generated in relation between lift and rotation angle of a control shaft due to disassembly and assembly of an engine.  <P>SOLUTION: The valve gear includes a target lift calculation part 162 for calculating target lift, a motor drive part 165 for driving a brushless DC motor 355 rotating the control shaft until the lift degree reaches a target lift degree, and an automatic deviation canceller 166 for automatically cancelling deviation. More specifically, the magnetic pole pulse pattern of the motor 355 before engine start is obtained, and it is determined if the pattern match magnetic pole pattern stored before engine stop. If they do not match, an idle lift degree is set, the idle lift degree is changed so as to keep engine speed within a tolerance range of idling speed, the rotation angle for the idle portion is subtracted from the obtained angle of the control shaft, and reference angle is updated by the difference.  <P>COPYRIGHT: (C)2009,JPO&INPIT
