    摘要: Various types of air cleaning devices for cleaning air fed to a passenger compartment of a motor vehicle are described. These air cleaning devices are arranged to incorporate with a cowl top structure of the vehicle. In one type, an air filter is disposed in an external air introduction passage led to the passenger compartment, and when the air filter is blocked with arrested dusts, a bypass passage is established to keep the feeding of atmospheric air to the passenger compartment. In a modified type, the bypass passage is instantly blocked and an internal air circulation mode is established. In one type, an electrostatic air collecting unit is used for arresting very fine particles in the atmospheric air fed to the passenger compartment. In order to achieve a smoothed air flow in the electrostatic air collecting unit, smoothly curved air guide passages are defined between positive and negative electrode plates. In one type, two hood ridge reinforcing hollowed structures are used for feeding the air box and thus the passenger compartment with a satisfied amount of atmospheric air. In order to facilitate the maintenance of the air filter in the air box, an inspection aperture is provided in the cowl top. Usually, the inspection aperture is covered by a lid.

    摘要: A sputtering process of a substrate biasing system and an apparatus for carrying out the same, capable of forming a film in satisfactory surface coverage over stepped underlying layer. The present invention solves problems in the quality of films formed by the conventional sputtering process of a substrate biasing system by regulating the bias potential of a substrate on which a film is to be formed so that the kinetic energy of ions of a sputtering gas falling on the substrate is varied periodically. The bias potential is regulated by periodically varying the amplitude of the output of a radio frequency (or dc) bias power supply or by changing the duty factor of a voltage pulse stream of the output of the radio frequency (or dc) bias power supply.

    摘要: A zinc-nickel alloy is electrodeposited on a steel strip by passing the steel strip through a stream of sulfuric acid-containing plating solution which contains 2-3 mol/liter in total of Zn.sup.2+, Ni.sup.2+, H.sup.+, and SO.sub.4.sup.2- ions and at least 0.1 mol/liter of Na.sup.+, K.sup.+, or NH.sub.4.sup.+ ion at pH 1 to 2.5, feeding the solution at a flow speed of at least 1 m/sec., and applying electricity between the strip and an anode in the solution such that the current density between the strip and the anode at the outlet of the solution is lower than that at the inlet of the solution. The anode may preferably be divided into a plurality of segments. This process may be carried out by use of a radial or horizontal cell.

    摘要: In a heating apparatus for motor vehicles, there is provided means for permitting part of air just heated by heater means provided in the apparatus to be directed toward a region upstream of the heater means so as to be again heated by the heater means, thereby causing the temperature in the vehicle chamber to be rapidly elevated, while at the same time preventing the humidity therein from being increased.
