摘要:
An exercising apparatus for full body exercise has a base member adapted to rest upon a floor and a support frame extending upwardly therefrom. The support frame has a pair of foot pedals pivotally attached thereto about midway of each foot pedal. A cross member attached to the upper end of the support frame has a pair of independently articulated pivotal arm handles rotatably attached to the cross-member. A pair of adjustable compressed spring tension devices are attached between each foot pedal and the upper cross member. A pair of actuating rods are pivotally attached respectively between each foot pedal and each arm handle, so that movement of either the arm handle or the foot pedal actuates the other member. Each of the two foot pedal-arm handle combinations is independently actuated, and not dependent on the other for movement. The foot pedals have pegs attached to the rearward ends to accommodate free weights; and the foot pedals have a solid member to tie the foot pedals together, as desired, to actuate both pedals together.

Disclosed is a method of converting butyric acid contained in a fermentation broth into biofuel. This chemical conversion method includes separating biohydrogen from gases generated in the course of production of butyric acid through fermentation of carbohydrate, extracting butyric acid from the broth using an insoluble solvent, esterifying butyric acid thus producing butylbutyrate, and hydrogenolyzing all or part of butylbutyrate, thus obtaining butanol. Thereby, biobutanol can be efficiently and economically produced, and butylbutyrate, which has oxidation stability superior to that of conventional biodiesel (fatty acid methyl ester) and is thus regarded as novel biofuel, can be produced together.

摘要:
A liquid crystal display (“LCD”) includes forming only a λ/4 plate between a polarizer and a display panel and setting a direction of an absorption axis of the polarizer and a slow axis of the λ/4 plate, so that the LCD can have a smaller thickness and its fabrication cost can be reduced while having better or the same characteristics than an LCD using both λ/2 and λ/4 plates. In addition, in an ECB mode backlit LCD, transmittance, contrast ratio, and viewing angles can be enhanced by attaching both the λ/4 or λ/2 plate and allowing the absorption axis of the polarizer and the slow axis of the λ/4 and λ/2 plates to have predetermined angle relationships.
摘要:
A frame configuration method and apparatus for sending data via an RS in a broadband wireless communication system are provided. In the reception mode, the RS monitors reception of data in an (n−1)th frame from an MS and reception of data in an nth frame from a BS. The RS classifies the data received from the MS and the data received from the BS as combinable data to be sent in combination or as non-combinable data to be sent separately, and stores the classified data distinguishably. When the RS transitions to a transmission mode, it determines whether to XOR-operate or mask the stored data. If the stored data can be masked, the RS XOR-operates the stored data and sends the masked data to the BS and the MS.
