  • Publication number: 20250020583
    Abstract: The present invention is a biological information detection device including: a laser oscillator that oscillates a pulsed laser beam oscillated at a suitable wavelength associated with a measuring target substance; an irradiation mechanism that emits the pulsed laser beam to a liquid biological object inside which the measuring target substance exists; a light receiving sensor that receives a detected laser beam output from the liquid biological object; and a control unit that controls operations of respective components. The control unit outputs an oscillation instruction to the laser oscillator so as to oscillate the pulsed laser beam at a constant cycle, cuts out a detected signal received from the light receiving sensor as time segment data for a time period corresponding to the constant cycle, and calculates a quantity of the measuring target substance in the liquid biological object based on the time segment data.

  • Patent number: 11557427
    Abstract: A coil component in which a change in thicknesses of the winding part is prevented is provided. According to the coil component, since each of a pair of neighboring resin walls and a seed part between the pair of resin walls are separated by a predetermined distance, a plating part grown on the seed part is easy to grow uniformly between the pair of neighboring resin walls. For this reason, the winding part whose surface is gentle and in which a change in thickness is prevented is obtained by plating growth.

  • Publication number: 20210270525
    Abstract: A method of recondensing boil off gas includes receiving liquefied natural gas from a storage tank and increasing the pressure of the received liquefied natural gas to produce increased pressure liquefied natural gas. The method further includes receiving boil off gas from the storage tank at a gas inlet of an ejector, and receiving the increased pressure liquefied natural gas at a liquefied gas inlet of the ejector. The pressure of the increased pressure liquefied gas is used as a motive force to eject combined liquefied natural gas and boil off gas at a pressure greater than that of the boil off gas received at the gas inlet of the ejector. The method additionally includes increasing the pressure of the fluid ejected from the ejector to produce increased pressure ejected fluid.

  • Patent number: 10210974
    Abstract: In a coil component (planar coil element), at least part of a third metal magnetic powder constituting a metal magnetic powder and having a minimum average grain diameter is uncoated, which suppresses a reduction in magnetic permeability. On the other hand, the remaining metal powders are coated with glass, which improves the insulating properties of a metal magnetic powder-containing resin and reduces core loss.

  • Patent number: 10147540
    Abstract: In a planar coil element and a method for producing the same, a metal magnetic powder-containing resin containing an oblate or needle-like first metal magnetic powder contains a second metal magnetic powder having an average particle size (1 ?m) smaller than that (32 ?m) of the first metal magnetic powder, which significantly reduces the viscosity of the metal magnetic powder-containing resin. Therefore, the metal magnetic powder-containing resin is easy to handle when applied to enclose a coil unit, which makes it easy to produce the planar coil element.

  • Patent number: 9973122
    Abstract: A sensorless electric motor control device is provided that completes a phase detection of a rotor before an activation signal is received, so as to shorten a time period from when the activation signal is received to when the rotor reaches a target number of rotations. The control device for a sensorless electric motor 10 includes an inverter 11 that drives the electric motor 10 and a first processor 18 that serves as a phase detection unit that causes the inverter 11 to perform a phase detection before the inverter 11 receives an activation signal that activates the electric motor 10, wherein the phase detection aligns a magnetic pole of a rotor of the electric motor 10 with a predetermined position with respect to a stator.
