There is provided a honeycomb filter including: a honeycomb base material; plugged portions; and a porous collecting layer disposed on the surface of the partition wall parent material in at least the remaining cells. The collecting layer has a constitution in which a plurality of particles combine or intertwine with one another, and the collecting layer includes flat plate-like particles as the plurality of particles. The plurality of particles are particles in which an average long diameter is 0.2 μm or larger and smaller than 10 μm, an average value of ratios (long diameters/short diameters) of the long diameters to the short diameters of the respective particles is smaller than 3, and an average value of ratios (the long diameters/thicknesses) of the long diameters to thicknesses of the respective particles is 3 or larger. An open area ratio of the surface of the collecting layer is 10% or larger.

A fuel tank structure includes: a fuel tank that is installed in an automobile and that accommodates fuel; a bag-shaped member that is fixed to a ceiling portion of an interior of the fuel tank, and whose state of contact with a liquid surface of fuel accommodated in the fuel tank is maintained due to the bag-shaped member inflating or deflating in accordance with a height of the liquid surface; a temperature sensor that senses a temperature of the fuel or evaporated fuel that is within the fuel tank; and a cooling wind introducing section that introduces cooling wind into an interior of the bag-shaped member in a case in which the temperature of the fuel or the evaporated fuel detected by the temperature sensor becomes higher than a predetermined temperature.

The present invention provides a heat pump type hot water supply device, which can suppress the increase of refrigerant pressure and the decrease of power coefficient when the inlet water temperature and the external air temperature become high. This heat pump hot water supply device includes: a compressor (1), a heat radiator (2) for hot water supply that exchanges heat between water and refrigerant, a first decompression device (3), and a The intermediate heat exchanger (10) for exchanging heat between the refrigerant and the external air, the second decompression device (11), and the evaporator for exchanging heat between the refrigerant and the external air are sequentially connected to form a heat pump cycle; detecting means (31) for detecting the inlet water temperature of the heat exchanger for hot water supply; detecting means (32) for detecting the temperature of outside air; and controlling means ( 30). Wherein, the valve opening of the decompression device is adjusted according to the detection value detected by the inlet water temperature detection device and/or the external air temperature detection device.

A thermal fuse includes an insulating case having a bottom and having an opening provided therein, a fusible alloy provided in the insulating case, a lead conductor having one end connected to the fusible alloy and other end led out from the insulating case through the opening of the insulating case, a flux provided on the fusible alloy, and a sealer for sealing the opening of the insulating case. The volume of a space between the fusible alloy in the insulating case and the sealer is larger than the volume of the flux. Sealing of the fuse is prevented from deteriorating, and the insulating film is prevented from damage even when the thermal fuse is used for breaking a large current at a high voltage.
