  • Patent number: 11764729
    Abstract: An oscillator includes: a resonator element; a circuit element configured to output a clock signal; and a container accommodating the resonator element and the circuit element and including a substrate having a first surface. The substrate includes a first electrode provided on the first surface and electrically coupled to the resonator element, a second electrode electrically coupled to the resonator element, and an output electrode configured to output the clock signal. The first electrode and the second electrode are disposed side by side in a first direction. The output electrode is disposed adjacent to the first electrode in a second direction orthogonal to the first direction. When an end portion of the first electrode on a side close to the second electrode is defined as a first end portion, the output electrode includes a first region disposed closer to the second electrode side than the first end portion in the first direction.

  • Patent number: 11563361
    Abstract: A coreless rotating electrical machine for being operated continuously comprises a stator including an energizable coreless cylindrical coil and a lid-type mount; and a rotor including a cup-type mount. The lid-type mount is equipped with a channel for supplying a refrigerant liquid to the air gap. The coreless rotating electrical machine is operated continuously by supplying the refrigerant liquid into the air gap, allowing the cylindrical coil, which generates heat, to vaporize the refrigerant liquid, cooling the cylindrical coil by latent heat of vaporization, and repeating an operation of supplying the refrigerant liquid to prevent a temperature of the cylindrical coil exceeding an allowable maximum temperature, and an operation of adjusting the supply of the refrigerant liquid to prevent the temperature of the cylindrical coil falling below a minimum temperature, so as to maintain the temperature in a range between the allowable maximum and minimum temperatures.
