Patent number: 11939896Abstract: A blowby gas return apparatus is provided that achieves inhibition of condensation of water vapor in blowby gas in branched return passages. A blowby gas return apparatus that returns blowby gas generated in an engine having a plurality of cylinders to an intake system of the engine includes a distribution portion inside a head cover of the engine, and distributes the blowby gas to intake paths of the cylinders. The distribution portion includes an introduction portion through which the blowby gas is introduced and a plurality of branch passages communicating with the introduction portion, plurality of branch passages branching from the introduction portion to communicate with the intake paths.Type: GrantFiled: March 21, 2023Date of Patent: March 26, 2024Assignee: MAZDA MOTOR CORPORATIONInventors: Takashi Kashiwabara, Yuki Tsukagoshi

Publication number: 20240039361Abstract: A rotating electrical machine includes a cylindrical housing having a flow path configured to allow a refrigerant to flow therethrough, an inlet configured to allow the refrigerant to flow into the flow path, and an outlet configured to allow the refrigerant to flow out of the flow path. The flow path being formed so as to spirally surround a circumferential surface of the housing. The flow path includes: a first flow path that is formed along one end surface of the housing and formed such that a width along the circumferential surface increases along a flow direction of the refrigerant from the inlet; and a second flow path that is formed along the other end surface of the housing and formed such that a width along the circumferential surface decreases toward the outlet along the flow direction of the refrigerant.Type: ApplicationFiled: March 8, 2021Publication date: February 1, 2024Inventors: Yuki TSUKAGOSHI, Yasuyuki KUBOTA

Patent number: 11821016Abstract: An objective of the present invention is to provide a culturing method, by which Bacillus bacterial spores can be efficiently produced. The present invention provides a method for producing Bacillus bacterial spores, comprising culturing Bacillus bacteria in a liquid medium containing a sugar or a sugar-source raw material at a concentration between 50.1 g/L and 100 g/L at the start of culture, and then in the course of the culture, feeding a fed-batch medium containing a sugar or a sugar-source raw material and a nitrogen-containing compound, and having the weight ratio (C/N ratio) of carbon atoms to nitrogen atoms ranging from 5.5 to 13.5 to the liquid medium.Type: GrantFiled: October 6, 2017Date of Patent: November 21, 2023Assignee: SDS BIOTECH K.K.Inventor: Yuki Tsukagoshi

Publication number: 20230155445Abstract: A drive unit includes an electric drive motor for driving and an electric generator motor in a series hybrid vehicle. Each of the motors includes a helical cooling passage helically surrounding an outer periphery of its stator. The first and second electric motors are housed in an outer housing such that the rotor axes are parallel. The helical cooling passages of the motors are connected in series via a connecting passage. The coolant outlet of the upstream helical cooling passage is connected to the connecting passage. The coolant inlet of the downstream helical cooling passage is connected to the connecting passage. The coolant outlet of the upstream helical cooling passage and the coolant inlet of the downstream helical cooling passage are arranged at end portions on the same side in a direction of the rotor axes.Type: ApplicationFiled: May 22, 2020Publication date: May 18, 2023Inventor: Yuki TSUKAGOSHI
