  • Patent number: 11574782
    Abstract: A switching device includes a first knob to receive a pressing operation in a first direction; a pressing detection switch to be pressed upon transmission of an operating force of the pressing operation; a decorative member to decorate a periphery of the first knob, that includes an engaged portion; and a holder to engage and hold the decorative member, that includes an engaging portion to engage the engaged portion. In response to the pressing operation by a first stroke amount, by the operating force transmitted to the pressing detection switch without transmitted to the engaged portion, the pressing detection switch is pressed. In response to the pressing operation by a second stroke amount greater than the first stroke amount, by the operating force applied to the first knob being transmitted to the engaged portion, the engaged portion elastically deforms, and engagement of the engaging/engaged portions is released.

  • Publication number: 20230024952
    Abstract: In an air-outlet unit that forms an air outlet of an air conditioner in an automobile, a light-emission control unit controls, in accordance with the airflow rate of the air conditioner that is obtained from an air-conditioning control device of the automobile, an LED driving unit that drives an LED array in such a manner that the amount of light that is emitted from the LED array and that activates a photocatalytic filter increases as the airflow rate of the air conditioner increases. The light that is emitted from the LED array is visible light, and some of the light that is reflected by the photocatalytic filter transmits to an area outside of the air-outlet unit by passing through fins that adjust the direction and the flow rate of the air blown by the air-outlet unit.

  • Publication number: 20230012785
    Abstract: In a speaker distortion correction device, an input signal passes through a nonlinear-portion correction filter and is input into a linear inverse filter. An output signal from the linear inverse filter is output into a speaker through an amplifier. For the nonlinear-portion correction filter, transfer characteristics (filter coefficients) are set that eliminate distortion due to nonlinear characteristics of the speaker. With a difference, as an error, between vibration of the speaker without distortion relative to an input signal and vibration of a vibration system of the speaker measured by a vibration measurement unit, an adaptive-algorithm execution unit performs an adaptive operation that adaptively updates filter coefficients of the linear inverse filter.

  • Patent number: 11480820
    Abstract: A display device improves ESD resistance while using a plurality of adhesive double-sided tapes for fixing a display. After an OGS and a liquid crystal display are bonded to each other to be integrated, an outer edge portion of the OGS is bonded and fixed to a frame housing a backlight unit by four adhesive double-sided tapes. The four adhesive double-sided tapes are arranged to substantially surround a central region with a slight gap between adjacent ones of the adhesive double-sided tapes. An end portion of each of the adhesive double-sided tapes is set to have a shape such that a narrow path is bent, rather than being straight, the narrow path being a space surrounded by end surfaces of the two adhesive double-sided tapes between the frame and the OGS and extending narrowly.
