Patent number: 9447851Abstract: A power transmission system transmits power from an internal combustion engine to a first and a second auxiliary device through an endless transmitting member. Prior to issuing of an engine start request, the first auxiliary device is actuated to move a tensioner pulley to a given position to increase the degree of tension of the endless transmitting member. The actuation of the first auxiliary device as an engine starter upon the issuing of the engine start request, therefore, enables a drive shaft of the engine to be rotated immediately within a required time to crank the engine. This achieves a quick start of the engine and results in a decrease in amount of time between the issuing of the engine start request and the actual start of the engine.Type: GrantFiled: December 17, 2014Date of Patent: September 20, 2016Assignee: DENSO CORPORATIONInventors: Hitoshi Noguchi, Hiroshi Okada, Tomoaki Nakano, Yoshihiro Yamashita, Yousuke Yamamoto, Kazuhisa Hara, Toshihisa Nakajima, Kazuki Matsuo, Toshikazu Mori, Shuhei Oe, Hikaru Kokumai, Kiyoshi Iwade

Patent number: 9328806Abstract: A power transmission system transmits power from a drive shaft of an internal combustion engine to a first and a second auxiliary device through a belt. An auto-tensioner extends or contracts to change the tension of the belt. A controller rotates the first auxiliary device in a reverse direction to loosen the belt to cause the auto-tensioner to extend to increase the tension of the belt and calculates a reversing timing when the drive shaft will be reversed as a result of increasing of the tension of the belt. The controller inhibits the tensioner body from contracting immediately before or when the reversing time is reached to keep the tension of the belt at an increased degree, thereby eliminating the slippage of the belt on each pulley without having to finely control the operation of the first auxiliary device when the internal combustion engine is started.Type: GrantFiled: December 16, 2014Date of Patent: May 3, 2016Assignee: DENSO CORPORATIONInventors: Hitoshi Noguchi, Hiroshi Okada, Shuzo Oda, Tomoaki Nakano, Yoshihiro Yamashita, Yousuke Yamamoto, Kazuhisa Hara

Publication number: 20160097765Abstract: An electrochemiluminescence method of detecting an analyte in a liquid sample and a corresponding analysis system. An analyte in a liquid sample is detected by first providing a receptacle containing a fluid comprising protein coated magnetic microparticles to a stirring unit. Stirring of the fluid is necessary since the density of the microparticles is usually higher than the density of the buffer fluid. Thus the microparticles tend to deposit on the bottom of the receptacle leading to an aggregation of the microparticles because of weak interactions. To obtain representative measurements a homogeneous distribution of the microparticles in the buffer fluid is necessary to ensure a constant concentration of microparticles for each analysis cycle. It is further necessary to provide disaggregation of the microparticles, which is also realized by stirring the fluid. Stirring is conducted with a rotational frequency that is adapted to the amount of fluid to be stirred.Type: ApplicationFiled: December 14, 2015Publication date: April 7, 2016Inventors: Ralf Kraus, Oliver Larbolette, Friedrich Staebler, Yoshihiro Yamashita, Yukinori Sakashita, Shinya Matsuoka, Michihiro Saito, Taku Sakazume, Kenichi Takahashi
