A releasing mechanism is provided to release the engagement of the engaging mechanism when force generated in vehicle crash acts on the air guide from its front side.

Abstract: The process for polymerizing olefins uses a plurality of series-connected polymerization reactors in which at least one of second and subsequent reactors is a vapor-phase polymerization reactor containing a multicomponent gas. The process comprises the steps of: taking the multicomponent gas out of the vapor-phase polymerization reactor; mixing the multicomponent gas with an inert gas which is lighter than at least one component of the multicomponent gas, thereby obtaining a mixed gas; compressing and/or cooling the mixed gas to liquefy a part of the multicomponent gas; discharging at least a part of a gaseous mixture comprising the inert gas and an unliquefied multicomponent gas out of a reaction system; and returning a fluid comprising the remainder of the gaseous mixture and the liquefied multicomponent gas to the vapor-phase polymerization reactor.

Abstract: The pressure control valve is structured such that a first port is formed on one side of a casing, a second port is formed on the other side, and, in the casing, there are disposed not only a positive pressure valve which, when the pressure on the first port side becomes high, can be moved to the second port side to thereby communicate with the second port side, but also a negative pressure valve which, when the pressure on the first port side becomes low, can be moved to the first port side to thereby communicate with the second port side. In the pressure control valve, there is provided flow passage expanding means which, which the positive pressure valve has moved to the second port side beyond a given distance, allows the first port side to communicate with the second port side.

Abstract: An annular groove is formed in a cap body of a cap. An elongated coupling member has a ring part formed integrally therewith, and is coupled to the cap as the ring part is engaged in the annular groove. The cap and the coupling member are each formed of electroconductive resin, and the surface resistance from the cap to the vehicle is set to be greater than or equal to 1×1012 &OHgr; and less than 5.30×1012 &OHgr;. Hence, when the human body is brought into contact with the cap, static electricity in the human body is discharged to the vehicle side, and no shock is imparted to the human body. In addition, the amount of residual charge also declines without causing secondary spark discharge.

Abstract: A circuit board capable of accomplishing an increase in current capacity and therefore a reduction in resistance of a through-hole conductive section each formed by filling a conductive paste in each of through-holes formed in a paper base insulating substrate by punching. A punching pin is thrust into the paper base insulating substrate provided on front and rear surfaces thereof with copper foil lands from a side of the front surface, resulting in the through-holes being formed. A drawing pin is inserted into each of the through-holes from a side of the rear surface of the insulating substrate through a rear opening of the through-hole, to thereby curve an inner peripheral portion of the rear copper foil land toward an interior of the through-hole and cut off any swell in the through-hole. The through-holes each are filled with the conductive paste, followed by curing the paste, so that the through-hole conductive section is formed for electrically connecting copper foil lands to each other.

Abstract: The present invention relates to a method for the fusion splicing of carbon coated optical fibers and to a method for providing reinforced performance of the spliced points. Concretely, carbon coated optical fibers are fusion spliced in an atmosphere containing less than 0.5 vol % of oxygen without the removal of the carbon coating. In order to minimize the amount of damage to the carbon coating resulting from the fusion, the decline in the failure probability of the optical fiber is controlled by means of applying moisture to the spliced part or by means of the adhesion of the oxidized carbon gases to the optical fiber. On the other hand, the carbon coating layer which was removed by oxidation at the time of the fusion splicing is recoated by means of a CVD reaction using a laser as a heat source. By means of this, the decline in the fatigue characteristics of the spliced part can be controlled.
