  • Patent number: 7113067
    Abstract: A wire-wound coil includes a core, electrodes, and a wire. The core includes a winding core for winding the wire and a pair of flanges. A depression is formed on the inner lower portion of each of the flanges. The depression has a curved surface that curves inward in a direction from the inner wall to the outer wall of the flange and smoothly connects with the peripheral wall of the winding core. The end portions of the wire are extended along the curved surfaces and the tips of the end portions are bonded to the electrodes. The end portions are in an unstressed state and prevent the generation of tension caused by the contraction of a coating agent.

  • Patent number: 5821507
    Abstract: An electric cooker is provided, which can grill foods by heat rays from a metal heating member using induction heating and is hardly affected by drops from the foods. This electric cooker comprises a work coil wound in a substantially pipe-like shape for generating an alternating magnetic flux, a metal heating member having a substantially pipe-like shape disposed inside and coaxially with the work coil for being heated by the alternating magnetic flux generated by the work coil so as to generate heat rays, and an insulator having a substantially pipe-like shape disposed between the work coil and the metal heating member. A wire mesh for supporting the foods is disposed adjacent to the upper opening of the insulator. A receiving pan is disposed adjacent to the lower opening of the insulator for receiving drops from the foods. The metal heating member preferably has a shape suitable for collecting the heat rays to the upper opening.

  • Patent number: 5083289
    Abstract: A temperature reference jacket includes an optical absorber for executing calorimetric measurement of optical power to be measured, a heater, a cooler, and a temperature sensor. The monitor monitors the optical power to be measured. A shutter selectively transmists/shields the optical power to be measured with respect to the optical absorber. A memory stores a first control amount for the cooler corresponding to the optical power to be measured and second and third control amounts for the heater in advance. A controller controls opening/closing of the shutter, reads out the first and second control amounts from the memory in accordance with the monitoring result from the monitor while the shutter is closed, and reading out the first and third control amounts from the memory while the shutter is open. The controller finely adjusts a voltage for the heater so that the temperature reference jacket and the optical absorber are set in an isothermal state while the shutter is closed and open, respectively.
