  • Publication number: 20190361043
    Abstract: A turbo rotation sensor, which is configured to be mounted on a turbocharger provided with a compressor including a rotary driven compressor wheel housed in a compressor housing, to detect rotation speed of the compressor wheel, is composed of a magnet rotatable integrally with the compressor wheel and having a plurality of magnetic poles in a circumferential direction of the compressor wheel, and a sensor section attached to the compressor housing and including first and second magnetic detection elements capable of detecting a magnetic field in a radial direction of the compressor wheel due to the magnet. The first and second magnetic detection elements are arranged side by side in the radial direction of the compressor wheel. The rotation speed of the compressor wheel can be measured based on a difference between detection results of the first and second magnetic detection elements resulting from a difference between their respective distances from the magnet.

  • Patent number: 10487680
    Abstract: A turbo rotation sensor includes a magnet magnetized with two different magnetic poles along a circumferential direction about a rotating shaft of a compressor wheel and provided at an end portion of the compressor wheel on the air intake side, and a sensor portion that is housed in a sensor hole formed on the housing, is arranged to face the magnet in a radial direction of the rotating shaft, and includes two magnetic field detecting elements capable of measuring variation in magnetic flux density caused by the magnet. The two magnetic field detecting elements are aligned in a direction parallel to the rotating shaft so that the respective detection axes are parallel to an axial direction of the rotating shaft. The rotational speed of the compressor wheel is detected based on a difference between the magnetic field strengths detected by the two magnetic field detecting elements.

  • Patent number: 10446838
    Abstract: Cycle characteristics of a nonaqueous secondary battery are to be improved. An active material including: a first active material that contains a nano silicon produced by heating a layered polysilane represented by a composition formula (SiH)n and having a structure in which multiple six-membered rings formed from silicon atoms are connected; and a second active material that contains a graphite, is used in a negative electrode. With this, expansion and contraction due to stress during charging and discharging can be mitigated, and thereby cycle characteristics improve.
