A proton conductor for fuel cells including a hydrophilic block and a hydrophobic block, an electrode for fuel cells employing the same and a fuel cell employing the electrode. The proton conductor, which is phosphoric acid based mono-ester or di-ester including an amphiphilic block, is added during the preparation of catalyst layers, and thus the viscosity of the composition may decrease and the dispersion thereof can be improved. Since the proton conductor has an amphiphilic property, the distribution of phosphoric acid can be effectively controlled. Thus, efficiency of the catalyst is improved, and fuel cells having improved efficiency can be prepared by employing an electrode including the catalyst.

A monolithic nozzle assembly formed with a mono-crystalline silicon substrate includes a damper for temporarily storing an incoming fluid, and a nozzle having a pyramidal portion and an outlet portion, the pyramidal portion for guiding the flow of the fluid from the damper toward the outlet portion and for increasing the pressure of the fluid, and the outlet portion through which the fluid is discharged, wherein the damper, and the pyramidal and outlet portions of the nozzle are aligned with each other and formed in the single mono-crystalline silicon substrate by continuous processes. The monolithic nozzle assembly can be formed with a single (100) mono-crystalline silicon wafer. Compared with a complicated nozzle assembly formed using a great number of silicon wafers and plates, the configuration of the monolithic nozzle assembly is simple, and can be manufactured on a mass production scale by semiconductor manufacturing processes.

Micro lens manufacturing apparatus, a micro lens manufacturing method, a micro lens, and a camera module employing the micro lens are provided. First mold is manufactured in correspondence with a first lens profile of a lens element. Second mold is manufactured in correspondence with a second lens profile of the lens element. Second mold is aligned on a surface of a lens substrate having a hollow hole formed thereon. Material for the lens element is supplied into the hollow hole of the lens substrate. First mold is aligned on the other surface of the lens substrate having the hollow hole and compressed to form the first and second profiles of the lens element. Formed lens element hardened. First and second molds are separated from each other. Therefore, time and cost for manufacturing the micro lens are reduced, and the accurate alignment between the first and second lens profiles is achieved.

A writing implement has a bar type lead element, a container formed as a hollow member having one and opposite ends being open, a supporting shaft inserted in the container to be moved therein linearly in an axial direction, the supporting shaft being formed as a hollow member having a center hole pierced therethrough, and an adjustment member movably connected to a rear end of the container to be rotated, the rotation of the adjustment member causes the supporting shaft to be linearly moved in the container, the adjustment member being formed as a hollow member having one and opposite ends being open to be in fluid communication with the center hole 42. Accordingly, the raw material of the lead element is injected into the container from a rear end of the adjustment member through the center hole, and solidifies into the lead element, and the lead element is supported on the front end of the supporting shaft at its rear end, and moved in accordance with the movement of the supporting shaft. Accordingly, the raw material in melt state can be injected into the container with all the main parts being assembled in place. As a result, the manufacturing process becomes simplified, and the automation of assembly line can be achieved easily.
