摘要:
Disclosed herein is an electric bicycle. The electric bicycle includes a battery, a generator to generate voltage by operation of pedals, and a pedal load adjustment unit to adjust pedal load applied to the pedals by controlling voltage generated from the generator and used to charge the battery. The pedal load adjustment unit includes plural capacitors configured to be charged with the voltage generated from the generator and plural switches configured to operate alternately so that the voltage generated from the generator is discharged to the capacitors to charge the capacitors and the voltage stored in the capacitors is discharged to the battery to charge the battery.

The present invention provides a cosmetic composition containing one or more selected from a group consisting of green tea saponin and green tea polyphenol as active ingredients. The cosmetic composition of the invention is very safe to the skin and can greatly enhance biological mechanisms in the skin, and thus can serve as an anti-aging cosmetic composition.
摘要:
Disclosed is a plastic heat exchanger in which, when a heat exchanger tube of the plastic heat exchanger is coupled to a header, the heat exchanger tube and a junction portion of the header are melted and pressed simultaneously through a heat fusion jig including a fusion portion and a fusion valley so as to secure reliability against leakage of refrigerant, and a method of manufacturing the same, by which the plastic heat exchanger can be mass-produced at low fabricating cost through simple processes. The present invention provides a method of fabricating a plastic heat exchanger, comprising a step of melting and pressing a plastic heat exchanger tube and a junction of a header by using a heat fusion jig, and a plastic heat exchanger fabricated by the method, thereby securing reliability against leakage of refrigerant, having heat exchange performance more excellent than or equal to a metallic heat exchanger and also mass-producing the plastic heat exchanger at low fabricating cost through simple processes.
