摘要:
An air conditioning apparatus for a vehicle includes an air conditioning case for forming an air passage through which air is blown into a passenger compartment. In the air conditioning apparatus, during a cooling mode for cooling a passenger compartment, an inside/outside air introduction mode is switched from an inside/outside air-mixing mode where both inside air and outside air are introduced into the air conditioning case to an entire outside air mode where only outside air is introduced into the air conditioning case, when an engine of the vehicle is stopped and the cooling load is smaller than a predetermined cooling load. Therefore, air-suction noise from an inside air introduction port is not caused, and the air-suction noise is not noted by a passenger in the passenger compartment even when the engine is stopped. Thus, noise of the air conditioning apparatus in the passenger compartment can be reduced.

In an air conditioning apparatus for a vehicle, a double layer flow mode is set when the maximum heating state is set during an air outlet mode where both a foot opening portion and a defroster opening portion are opened. During the double layer flow mode, an air passage of an air conditioning case is partitioned into a first air passage through which inside air flows and a second air passage through which outside air flows, in such a manner that the first air passage communicates with the foot opening portion and the second air passage communicates with the defroster opening portion. When the double layer flow mode is set, the maximum rotation speed of a blower for blowing air is reduced by a predetermined level as compared with an entire outside air mode or an entire inside air mode. Thus, heating capacity for a passenger compartment of the vehicle can be improved.

An antifouling composition for coating fishnets consisting essentially of (A) at least one phenol compound represented by the formula: ##STR1## or the formula: ##STR2## (in which Y is hydrogen atom or hydroxyl group; ##STR3## m is 0 or 1; n is an integer of 1-5; R is a linear or branched alkyl having 4 to 21 carbon atoms), (B) at least one water-repellent organic compound selected from silicone oil, petroleum wax and liquid paraffins, and (C) at least one antifouling agent selected from fluorodichloromethyl thiophthalimide, dimethylphenyl fluorodichloromethyl thiosulfamide and dichlorophenyl dimethyl urea, the amount of said (C) being 0.5-20 wt % of the total of (A)+(B)+(C).The present antifouling composition is specifically effective for the prevention of attachment, and proliferation of noxious aquatic organisms including both of an animal and botanical nature.
摘要:
New tetraarylboron-ammonium complexes having the general formula: ##STR1## wherein R.sub.1 represents a hydrogen or a halogen atom or a lower alkyl group; R.sub.2 represents a halogen atom or a lower alkyl or a lower alkenyl group; and R.sub.3 represents a heterocyclic amine are provided as active ingredient of anti-fouling paint and also of antiseptic, antifungal agent. These compounds exhibit remarkably long-lasting anti-fouling activities against substantially all kinds of aquatic organisms including slimes with acceptably low toxicity against human beings and also exhibit high antimicrobial activities against various fungi, bacteria and yeasts.
摘要:
A bioactive substance control-releasing resinous composition comprising a resin having main chain and side chains, at least one side chain bearing at the end portion thereof an organic acid moiety having a biological activity, through a metal ester bonding. The resin is hydrolyzed in an ionic atmosphere at a controlled rate to generate a bioactive substance as well as metal ions and is useful in various fields and especially as a resinous vehicle for a coating composition.
摘要:
The present invention relates to a hydrolyzable resin composition based on the resin having at least one side chain bearing a particular metal containing terminal group. The invention also concerns an antifouling coating composition containing said hydrolyzable resin composition as a vehicle.
摘要:
A hydrolyzable resin composition consisting essentially of a resin selected from the group consisting of an acrylic resin, a polyester resin and an epoxy resin and an organic solvent in which the resin is soluble, wherein said resin has at least one side chain bearing at least one terminal group of the formula: ##STR1## wherein X represents ##STR2## M is a metal selected from zinc, copper and tellurium; x is an integer of 1 to 2; R represents an organic acid residue selected from ##STR3## and R.sub.1 is a monovalent organic residue, and the metal content of said resin is 0.3 to 20% by weight of the resin.The subject composition provides superior antifouling coating compositions.
摘要:
A toothed belt has a plurality of teeth, which are arranged in the longitudinal direction thereof, and cords embedded in a back portion of the toothed belt. A facing fabric is covered over the teeth. The fabric used for the facing fabric is coated with latex. The solid deposition of latex is adjusted to between 50 and 200 wt % with respect to the weight of the base cloth.
摘要:
An antifouling paint composition comprising a binder resin composition containing a biodegradable resin being obtained by polymerizing a cyclic lactone compound with at least two active hydrogen groups of a compound containing at least two active hydrogen groups in one molecule, and an antifouling additive being mixed with the binder resin composition in a weight ratio of the binder resin composition to the antifouling additive from 1:2 to 7:1, the binder resin composition having a gel fraction of not more than 5% by weight.
摘要:
A method for preventing settlement of aquatic fouling organisms on surface of an aquatic structure without environmental hazard is provided. The method is based upon absolutely novel concept to prevent the settlement by means of thick slime layer, i.e. bio-jelly, deposited on said surface. The present invention also provides a bio-jelly producing agent and a bio-jelly producing paint both useful for the present method. Further, the present invention provides a novel low toxic antifouling agent.
