摘要:
A tubular body 101 includes a layer containing a resin and conductive particles 112, the layer having a first region 111C that is free of conductive particles and lies at the outermost surface, and a second region 111B that has higher conductivity than other regions and lies closer to the innermost surface than the first region. A coating film of a coating liquid containing the conductive particles and resin material is dried, and then an eluting solvent for eluting the resin material from the film is applied thereto. As a result of this, the conductive particles are localized in the coating film at the side coated with the eluting solvent. Thereafter, upon drying the eluting solvent, the resin material dissolved in the eluting solvent deposits on the region where the conductive particles are localized, whereby a particle-free resin region free of the conductive particles is formed.

摘要:
A crank angle detector in which a rotary body rotates in association with a crankshaft of an engine and has portions to be detected every predetermined angle and at least one of the portions to be detected is lacking, and first and second pickups positioned near the outer periphery of the rotary body with a fixed angle difference therebetween, for generating first and second pulses each time the portion to be detected passes. When a number of second pulses equal to or more than a predetermined number are detected after the first pulse has been detected, the crank angle detector sets the time the first pulse is newly detected, as a reference position time for a rotating angle of the crankshaft.

In a vehicular air conditioner, in which an air flow passage for directing air sucked horizontally through a suction port upward in a casing having a plurality of blowout ports at the upper part and said suction port at the lower part, and an evaporator, air mix damper, heater, and blowout mode switching damper for selectively switching the plural blowout ports are arranged in the air flow passage, the evaporator can be replaced easily and rapidly, and the contamination of the surroundings, caused by the drain which drops from the evaporator when the vehicle is inclined and flows back into the blower case and drops from it by leaking, is prevented. For this purpose, the evaporator is disposed at a portion where the direction of air changes from horizontal to upward in the air flow passage so as to be tilted in such a manner that the suction port side end thereof is high than the opposite side end, and the casing is divided into a plurality of sections, and also one of the divided casings forms the upper half part of the suction port and is configured as an evaporator detachable cover for covering one side of the evaporator so that the evaporator can be pulled out of the casing by removing the cover.
