Method and apparatus for applying a sealing material to vehicle bodies which are arranged in series such that front and rear sections of the bodies face each other. A first and a second sealing robots are provided on transversely opposite sides of the vehicle bodies. The first sealing robot is operated to apply the sealing material to one of two areas in an engine room covered by an engine hood of one of the two successive bodies, and the second sealing robot is operated to apply the sealing material to the other area in the engine room, or to one of two areas in a luggage compartment covered by a luggage compartment door of the other of the two successive bodies. The two areas in each of the engine room and the luggage compartment are divided by longitudinal centerlines of the two successive bodies. The first and second sealing robots are further operated to apply the sealing material to the areas in the engine room and luggage compartment, respectively, which areas have not been sealed.

摘要:
Disclosed is a terminal constructed in such a manner that at least an outer portion of the terminal including a region corresponding to a last-contact part of the terminal with a counterpart terminal when the terminal is disengaged from the counterpart terminal is formed of an insulating member. A conductive layer is formed on the surface of the insulating member to be electrically connected to a conductive part of the terminal. The terminal is constructed in such a manner that the conductive layer is detached from the counterpart terminal at a final stage of disengagement of the terminals. With this arrangement, arc discharge at the disengagement of the terminals is suppressed.
摘要:
A method for preventing microorganism multiplication, including using a gas containing a low concentration of ozone and a high concentration of ions, so that the multiplication of microorganisms can be safely and fully prevented by an additive effect of the ozone and ions. The generation of ozone is suppressed by reducing the discharge current in the ionization chamber using a pulse converter, which is provided to control the current flowing at the time of discharge, when generating the ions and ozone in the ionization chamber. Ions are produced in the ionization chamber in a high concentration to produce and supply ionized gas containing a low concentration of ozone and a high concentration of ions, which prevents microorganism multiplication on the objects.
