A door includes an apparatus for reducing smoke associated therewith. The door is particularly advantageous in reducing smoke in a fire to thereby allow a firefighter or a victim trapped in a fire to readily indentify an exit. The door includes a nozzle or plurality of nozzles mounted upon the door, with a liquid source connected to the nozzle. Preferably, the door additionally includes a supply of pressurized water therein, with a surface active agent in an amount of 0.1 to 3,000 ppm disposed in the supply of pressurized water

Disclosed are a process for laminating a functionally gradient material and a laminating apparatus for the same. The process therefor includes a suspending step and a functionally gradient material laminating step. In the functionally gradient material laminating step, solid-liquid separation is carried out to a suspension while varying the mixing rates of the suspension particles contained therein continuously or in a multi-staged stepwise manner. Therefore, the functionally gradient material layer thus laminated offers a composition gradient varying continuously or in a multi-staged stepwise manner in the thicknesswise direction thereof in a superior continuity, and the composition fluctuates less in the planewise direction thereof. In addition, the process and the laminating apparatus have obviated the atomizing and the spraying which adversely affect a working environment.

Disclosed is an exhaust gas purifying apparatus for an automobile diesel engine including a pair of electrodes disposed at a predetermined interval in an exhaust path of an automobile diesel engine, and a high voltage power source for applying a high voltage to the pair of electrodes whereby an electric field is generated in a space between the pair of electrodes so as to collect diesel particulates. Since the diesel particulates emitted from a diesel engine are charged heavily in negative, and since the exhaust gas purifying apparatus forms an electric field between the pair of electrodes, the diesel particulates are collected on one of the pair of electrodes. Hence, in accordance with the exhaust gas purifying apparatus, it is possible to purify the exhaust gas without substantially increasing the exhaust gas pressure loss of the diesel engine, without deteriorating the output of the diesel engine resulting from the pressure loss and without deteriorating the combustion reaction in cylinders of the diesel engine. In addition, it is possible to down-size the exhaust gas purifying apparatus remarkably compared with a conventional apparatus employing a ceramic filter.

A wiper controller which detects the raindrops adhered onto the windshield glass G of the vehicle to control the wiper based on the detected result is provided with a wiped water measurement unit for calculating an amount of water wiped by the wiper, a wiper operation time counter for counting the actual wiper operation time based on the ON/OFF signal of the wiper motor for driving the wiper, a delay time calculation unit which obtains the wiper operation delay time by comparing the actual wiper operation time with the reference wiper operation time, and an operation change determination unit for determining with respect to the need for changing the wiper operation based on the wiper operation delay time and the amount of water wiped by the wiper. The change in the rainfall state is derived from the wiper operation delay time and the amount of water wiped by the wiper to appropriately control the wiper in response to the change in the rainfall state.
