    Abstract: A fluid discharge device includes a base portion defining a fluid flow passage and having an opening at a downstream end of the fluid flow passage, and a grill portion disposed to adjust a flow direction of the fluid blown from the opening. The grill portion includes a flow passage forming body defining a main flow passage and an auxiliary flow passage. In the flow passage forming body, the auxiliary flow passage surrounds the main flow passage and the auxiliary flow discharged from the auxiliary flow passage flows outside of the main flow discharged from the main flow passage. The flow passage forming body is configured such that a direction of the auxiliary flow discharged from the auxiliary flow passage corresponds to the direction of the main flow discharged from the main flow passage, when the flow direction of the fluid blown out of the opening is adjusted.

  • Patent number: 10670819
    Abstract: A non-plated region is formed in a certain range from an end of a submount. The non-plated region is a portion where a plating layer is not provided, and thus a substrate of the submount is exposed. An intermediate layer is formed on the plating layer. Furthermore, a plating layer is formed on the intermediate layer. A semiconductor laser is formed on the plating layer. The position of an end of the semiconductor laser substantially coincides with the position of an end of the plating layer (the intermediate layer). That is, even in a case where there is a deviation between an end face of the intermediate layer and an end face of the semiconductor laser, the amount of this deviation is sufficiently smaller than the amount by which the intermediate layer is set back from an end face of the submount.

  • Patent number: 10414248
    Abstract: A humidification device is used in a vehicle air conditioner having a cooler disposed in an air conditioning case. The air conditioning case has a ventilation path leading air into a vehicle compartment. The humidification device has an adsorber that absorbs and desorbs moisture, a blower, a door that opens or closes an air flow path, and a controller. The controller switches the air flow path by controlling the door to set (i) a dehumidification mode in which air cooled by the cooler is led to the adsorber, and moisture in the air is adsorbed by the adsorber or (ii) a humidification mode in which air is led to the adsorber, the moisture is moved from the adsorber to the air to humidify the air, and the humidified air is blown toward an occupant.
