The present invention relates to methods and compositions which employ low concentrations of combinations of zinc salts to prevent the irritation of skin or mucous membranes that may be caused by therapeutic agents, by personal hygiene products, or by various physical, chemical, mechanical, or biological irritants, including infectious agents.

The present invention provides for compositions and methods that may offer protection from irritants, as well as antimicrobial protection. Preferred embodiments of the invention include topical antimicrobial compositions comprising two or more water-soluble zinc salts in low concentrations.

The addition of low concentrations of combinations of water-soluble organic salts of zinc to gels, creams, lotions or ointments can increase the ability of these products to reduce or prevent exogenous irritants from causing irritation of the underlying substrate. The addition of low concentrations of combinations of water-soluble organic zinc salts to these gels, creams, lotions or ointments also can reduce the irritation of skin or mucous membranes caused by the addition of potentially-irritating substances such as spermicides, microbicides, fungicides or other therapeutic agents to the gel, cream, lotion or ointment. The advantages of this anti-irritant approach over others, which generally employ high concentrations of single zinc salts, are the reduced potential for zinc toxicity, the reduced potential for toxicity related to zinc itself, and the preservation of the desirable biological properties of potentially-irritating therapeutic substances added to the gel, cream, lotion or ointment.

A scroll compressor includes a fixed scroll having a fixed wrap, and an orbiting scroll having an orbiting wrap engaged with the fixed wrap to define a first compression chamber between an inner surface of the fixed wrap and an outer surface of the orbiting wrap, and to define a second compression chamber between an inner surface of the orbiting wrap and an outer surface of the fixed wrap. A rotation shaft is provided with an eccentric portion at one end thereof to drive the orbiting scroll. A protruding portion protrudes inwardly from an inner end of the fixed wrap, and contacts the orbiting wrap. A distance between a center of the eccentric portion and a tangent line at a contact point between the protruding portion and the orbiting wrap at an end of the first compression chamber is smaller than a radius of the eccentric portion.

A friction material composition containing a fibrous material, a binder and a friction adjusting agent, wherein the friction adjusting agent is secondary aggregates of an activated alumina being spherical and having a diameter of 10 to 300 μm, or an activated alumina having a specific surface area of 100 to 400 m2 / g and an average particle diameter of 1 to 200 μm. The composition can be used for producing a friction material which exhibits significant improvement with respect to fading phenomenon, without adversely affecting its characteristics of attacking to a disc rotor, which is the article mating therewith, and without marked reduction of the friction coefficient at an elevated temperature, and is capable of controlling the thickness of the sliding film formed on a frictionally sliding face and preventing a high frequency noise (grabbing chatter).

The invention provides a portable device, a communication device, and a communication system with high prevention and capable of determining whether relay attack is performed. The communication system (100) includes: a vehicle (1)-mounted communication device (20) and a portable device (10). The communication device (20) includes: a vehicle transmission unit (22) which transmits a plurality of first signals to the portable device, and a vehicle reception unit (21) which receives a second signal transmitted from the portable device. The portable device (10) includes: a portable device reception unit (11) which receives the first signals, a portable device controller (15) which detects signal intensities of the received first signals, and which compares the signal intensities of the first signals, and a portable device transmission unit (12) which transmits the second signal according to control of the portable device controller. The portable device controller (15) sets an output value of the second signal to a predetermined value when a difference between the compared signal intensities of the first signals is equal to or less than a threshold.

The present invention provides for compositions and methods that may offer protection from irritants as well as antimicrobial protection. Preferred embodiments of the invention include topical antimicrobial compositions that lack conventional antibiotics or preservatives, wherein the antimicrobial benefit is created by essential oils (or their active ingredients), emollient solvents and, in some instances, anti-inflammatory agents.

A pneumatic tire which positively discharges water having flowed into a groove extending in the tire circumferential direction and enhances capability of preventing hydroplaning. The groove is provided in the tread face of the tire and extends in the tire circumferential direction. The wall face of the groove is provided with line portions composed of a plurality of ridges or recesses that are inclined in one direction with respect to the groove longitudinal direction.

The invention discloses an earthquake disaster risk assessment and countermeasure analysis system. The system starts from five aspects of earthquake disaster risk investigation management, earthquakedisaster risk assessment, earthquake disaster loss pre-assessment, earthquake disaster risk treatment auxiliary decision and earthquake disaster risk assessment public service.
