    Abstract: An inverter that controls a rotary electric machine is above the rotary electric machine and overlaps the rotary electric machine when viewed in a vertical direction. A differential gear assembly includes a differential input gear being an input element in the differential gear assembly. The differential input gear is at least partially located in an oil reservoir in a case and is located on a second axis different from a first axis being a rotation axis of a rotor in the rotary electric machine. The first axis is below the second axis. The rotor has a lower end located above a lower end of the differential input gear.

  • Publication number: 20240401691
    Abstract: A vehicular drive device includes a rotating electrical machine, transmission mechanism, case, and communication oil passage. The case includes a first housing chamber housing the rotating electrical machine and a second housing chamber housing the transmission mechanism. The communication oil passage communicates with the first and second housing chambers. The lower part of the second housing chamber forms a second oil reservoir where oil is scraped up by gear rotation. The case includes a partition wall between the first and second housing chambers axially. The communication oil passage runs under the partition wall and includes a first and second opening. The first opening opens to the first housing chamber at a first position away from the partition wall toward the first side in the axial direction. The second opening opens to the second housing chamber at a second position away from the partition wall toward the second side axially.

  • Patent number: 5389769
    Abstract: An ID recognizing system for a semiconductor manufacturing system includes IC modules set in surfaces of containers which accommodate wafers and are conveyed from one device to another in the semiconductor manufacturing system. Each IC module is capable of transmitting and receiving signals from fixed stations and includes a reloadable memory. The semiconductor manufacturing system is made up of a number of devices for performing manufacturing operations on the wafers in the containers, and each of the devices include one of the fixed stations. The IC module is powered by the energy of radio waves received from the fixed station in the device in which said container has been placed for processing of the wafers therein.
