摘要： There is disclosed a method for fabricating a camera module includes the steps of: disposing a camera module body inside of a die; filling the die with a resin blocking a light; curing the resin; and removing the camera module body and the resin from the die. Here, disposing the camera module body inside of the die is disposing the camera module body having a lens holder secured on a sensor board inside of the die in such a manner that the side surface of the camera module body is not brought into contact with the side surface of the die. Filling the die with the resin is covering the upper end of the die with a lid so as to closely enclose the inside of the die, followed by filling the die with the resin. Taking the camera module body and the resin from the die is taking, from the die, the camera module body and the resin formed around the camera module body in close contact.

摘要： In a gas humidifier used for humidifying fuel in a molten carbonate fuel cell (MCFC), a small-size gas humidifier is achieved by carrying out a steam-generating process and a gas humidifying process by the use of the steam by using a single unit. In order to achieve this structure, a plurality of longitudinal tube plates are laminated in a thickness direction with predetermined intervals so that a heat-exchanger core (100) of a plate-fin type is prepared. Heating-use high-temperature fluid (A) is allowed to flow alternately through a plurality of spaces that are formed inside the heat-exchanger core (100) and placed side by side in the horizontal direction so as to direct a gas to be humidified (B) to another space from above to below. An injection tube (210), which is used for spraying liquid (C) that serves as a steam source, is inserted virtually horizontally along tube plates on two sides in an upper portion of each space through which the gas to be humidified (B) flows. A header pipe (220), which is used for supplying the liquid (C) to the injection tube (210), is connected to the injection tube (210) at a place apart from the heat-exchanger core (100). One portion of the gas to be humidified (B) that has been introduced into the heat-exchanger core (100) is allowed to flow outside the heat-exchanger core (100) and to contact the header pipe (220) placed outside thereof.
