Abstract:
Disclosed is a mat for exercise. The mat comprises a main mat having a foot hanger for a sit-up at a top surface of one side thereof and a plurality of grooves at a bottom surface of both lateral sides thereof, a plurality of sub-mats coupled with the main mat in use, and a plurality of attachment plates installed at corners of a bottom surface of the main mat and corners of bottom surfaces of the sub-mats, wherein the main mat is provided with female Velcro tapes mounted at the grooves thereof, and the sub-mat is provided with male Velcro tapes that laterally protrude corresponding to the grooves of the main mat.
Abstract:
A transmission and a motor or non-motor type transport device including a cross-coupling power train using the transmission, such as chainless bicycle or wagon with two or four wheels are disclosed. The transmission includes a coarse adjustment gearshift of internal gear type and a fine adjustment gearshift of differential gear type which are mounted on a main shaft to change the speed and are selectively connected to each other by a shift lever to provide low-speed rotation and high-speed rotation.
Abstract:
The present invention relates to the urban roadway system and accompanying underground railway system, which provide the efficient use of limited constructible areas of the congested cities, and also relates to the traffic flow control system capable of the effective control of vehicular movements through the roadways. In the whole or partial areas of a city, the roadway network is constructed and connected in the honeycomb-like net structure. Compared with a typical tetragonal city, the hexagonal city of the present invention can reduce 22% of road extent, 63% of road area and 30% of constructible area in total, and the traffic flow can be improved enormously. The present invention also proves that the hexagonal roadway system enables vehicles to move in average 75% less time without meeting stop-signals by the synchronized signal system for traffic flow controls
Abstract:
An iron core built in a transformer, a rectifier, a stabilizer, a lamp, and others is disclosed. When the iron core is formed, an E-shaped iron core and a pair of c -shaped iron cores, which are arranged on both sides of the E-shaped iron core, are simultaneously stamped from a sheet of silicon steel. A predetermined number of E-shaped iron cores and pairs of c -shaped iron cores are assembled and laminated to form a laminated iron core. The iron core includes the E-shaped iron core having side legs symmetrically formed on both sides thereof and a center leg formed between the side legs and coupled to a bobbin around which a coil is wound, and the pair of C-shaped iron cores each having a long leg formed corresponding to the side leg of the E-shaped iron core and a short leg formed corresponding to the center leg of the E-shaped iron core.
Abstract:
The present invention relates to a discriminatory mileage offering method by load factor and a computer readable record medium on which a program therefor is recorded, wherein more mileage is offered when a load factor of an airplane is low while less mileage is offered when the load factor is high, thereby maximizing the satisfaction of airlines and passengers. To this end, the present invention provides a discriminatory mileage offering method, comprising a first step of building a mileage database (DB) using mileage applied discriminatively according to a load factor; a second step of receiving passenger boarding information from a terminal that makes communication connection over an information communication network, and storing and managing the boarding information in a customer information database (DB); a third step of calculating a load factor based on the received boarding information, and retrieving mileage corresponding to the calculated load factor from the mileage database (DB); and a fourth step of extracting a passenger to which the mileage retrieved through the third step is to be offered, offering the mileage to the extracted passenger, and storing and managing the offered mileage and information on the passenger in the customer information database (DB).
Abstract:
The present invention relates to nanoemulsions, the use thereof and preparation method thereof wherein, nanoemulsions contain polyoxypropylene-polyoxyethylene vitamin E as emulsifiers and polyacrylic acid or polyacrylic acid derivative crosspolymers as emulsion assistants, In the present invention nanoemulsions containing POP-POE vitamin E as emulsifiers and polyacrylic acid or polyacrylic acid derivative crosspolymers as emulsion assistants have a very small mean droplet diameter ranging from 43 to 96 nm and are very stable and safe. By using the nanoemulsions described above the inventors prepared nanoemulsion cosmetic compositions with a much smaller mean droplet diameter than nanoemulsions prepared only with emulsifiers, polyoxypropylene-polyoxycthylcne vitamin E. The nanoemulsion cosmetic compositions in the present invention have good effects such as skin softening, skin moisturizing, improving dry atopy skin, skin firming and good spreadability when applied on the skin. Particularly, nanoemulsion skin treating compositions in present invention have an advantage of having a long lasting effect of skin treating due to the favorable penetration of active drug components into the skin.
