  • PRODUCTION METHOD FOR FABRY-PEROT INTERFERENCE FILTER
    Publication number: 20180373021
    Abstract: A method of manufacturing a Fabry-Perot interference filter includes a forming step of forming a first thinned region, a first mirror layer, a sacrificial layer, and a second mirror layer are formed on a first main surface of a wafer, and the first thinned region in which at least one of the first mirror layer, the sacrificial layer, and the second mirror layer is partially thinned along each of a plurality of lines is formed; a cutting step of cutting the wafer into a plurality of substrates along each of the plurality of lines by forming a modified region within the wafer along each of the plurality of lines through irradiation of a laser light, after the forming step; and a removing step of removing a portion from the sacrificial layer through etching, between the forming step and the cutting step or after the cutting step.

  • LIGHT-DETECTING DEVICE
    Publication number: 20180348054
    Abstract: A spectral sensor includes a wiring substrate which has a principal surface; a light detector which is disposed on the principal surface of the wiring substrate and is electrically connected to the wiring substrate; spacer which is disposed around the light detector, on the principal surface of the wiring substrate; and a Fabry-Perot interference filter which has a light transmission region and is disposed on the principal surface of the wiring substrate with the spacer therebetween. The spacer support the Fabry-Perot interference filter in a surrounding region of the light transmission region and the spacer is arranged to form opening communicating with an inner side of the surrounding region and an outer side of the surrounding region, when viewed from a light transmission direction in the transmission region.

  • Fixing device and image-forming apparatus
    Patent number: 10114337
    Abstract: An image-forming apparatus includes an image-forming unit, a fixing device including a heating rotator and a pressure member forming a nip portion together with the heating rotator, and a bias-applying unit applying bias to the heating rotator. Image forming modes each having a time interval between a preceding recording material and a succeeding recording material which is different from each other can be performed. A control unit executes a first control while the recording materials are being conveyed at the nip portion, and a second control while the recording materials are not being conveyed at the nip portion due to the time interval. A switching time in the image forming mode in which the time interval is a first time interval is determined to be longer than in the image forming mode in which the time interval is a second time interval shorter than the first time interval.

  • LIGHT DETECTION DEVICE
    Publication number: 20180292267
    Abstract: A light detection device includes: a Fabry-Perot interference filter provided with a light transmission region; a light detector configured to detect light transmitted through the light transmission region; a package having an opening and accommodating the Fabry-Perot interference filter and the light detector; and a light transmitting unit arranged on an inner surface of the package so as to close an opening, the light transmitting unit including a band pass filter configured to transmit light incident on the light transmission region. When viewed from a direction parallel to the line, an outer edge of the Fabry-Perot interference filter is positioned outside an outer edge of the opening, and an outer edge of the light transmitting unit is positioned outside the outer edge of the Fabry-Perot interference filter.

  • FIXING DEVICE
    Publication number: 20180203390
    Abstract: A fixing device includes a cylindrical film; a pressing member, and a preventing member including a preventing surface configured to prevent movement of the film in a longitudinal direction and a film rotation guiding surface. As viewed in the longitudinal direction of the film, the preventing surface includes first and second regions positioned downstream and upstream, respectively, of a nip center line with respect to a recording material feeding direction. The first region retracts from a longitudinal film end surface relative to the second region. The second region continuously extends in the recording material feeding direction from a portion upstream of a nip center line to a portion downstream of the nip center line, and has a length, with respect to a rotational direction of the film, longer at the portion upstream of the nip center line than at the portion downstream of the nip center line.

  • FIXING DEVICE
    Publication number: 20180203386
    Abstract: A fixing device includes a cylindrical film; a contact member, a nip forming member, and a regulating member provided at a longitudinal end portion of the film and including an inner surface regulating surface. As viewed in a longitudinal direction of the film, with respect to a rotational direction of the film, the inner surface regulating surface includes a first region remotest from the nip and a second region closer to the nip than the first region is. The inner surface regulating surface is inclined so as to be spaced from the inner surface of the film toward a longitudinal center of the film with respect to a longitudinal direction of the film, and a degree of inclination of the inner surface regulating surface is larger in the first region than in the second region.
