  • Patent number: 11951422
    Abstract: A filtration filter having a tubular shape, defining a first opening and a second opening facing the first opening, and including a filter base that defines a plurality of through holes arranged in a square grid array. The filter base includes a continuous portion having a first set of through holes of the plurality of through holes, and a non-continuous portion having a second set of through holes of the plurality of through holes. The continuous portion extends in a first direction from the first opening of the filtration filter toward the second opening and extends in a second direction along at least a first portion of a circumference of the filtration filter orthogonal to the first direction. The non-continuous portion has the second set of through holes shifted relative to the first set of through holes of the continuous portion and extends in the first direction.

  • Patent number: 10668873
    Abstract: A housing-securing unit for a vehicle includes: a housing in which a circuit board is to be housed; and a bracket through which the housing is mounted to the vehicle. A holding pin having a column shape is provided on a side surface of the housing. The bracket has a side support component in which a through hole is formed for fitting the holding pin. The holding pin has an inclined approach surface having a height that is increased as extending in an assembling direction, and a holding surface formed to regulate the side support component from moving in the assembling direction and to oppose an inner peripheral surface of the through hole when the holding pin is fitted to the through hole. A height of a top part of the holding surface is more than or equal to a height of a top part of the inclined approach surface.
