Abstract: An injection head is configured to discharge a liquefied fire-extinguishing agent. The injection head includes an injection head body configured to be connected to piping for supplying the liquefied fire-extinguishing agent; an orifice plate positioned in the injection head body, the orifice plate including orifices defined therein; a block-shaped porous member positioned at an outlet of the orifice plate; and a deflector positioned across from the block-shaped porous member such that a discharging clearance for the liquefied fire-extinguishing agent is defined.

Abstract: An injection head for liquid fire extinguishing agent that has an injection head including an injection head body connecting with a pipe providing the liquid fire extinguishing agent, an orifice plate arranged in the injection head body and formed with an orifice through which flowing the liquid fire extinguishing agent and, a porous member having a block shape arranged in an exiting part of the orifice and, a baffle plate arranged contacting with an end surface of the porous member opposite side of the exiting part of the orifice; and the baffle plate covers at least a projected area of a circumscribed circle of the orifice of the end surface of the porous member and, the liquid fire extinguishing agent is released via a gap formed between the injection head body and the baffle plate.

Abstract: An image forming apparatus includes an input device, an image forming device, and a control device. The control device includes a processor, and acts, when the processor executes a control program, as a controller that, upon receipt of an instruction to form a source document image on a first face of a plurality of recording media through the input device, causes the image forming device to form the source document image on the first face of the plurality of recording media, designates a recording medium on which a see-through prevention image, constituted of a predetermined pattern, is to be formed, out of the plurality of recording media, and causes the image forming device to form the see-through prevention image only on a second face, opposite to the first face, of the recording medium designated.
