摘要： The present invention relates to a phase retardation plate including a thin organic film with a phase retardation function due to birefringence and a fixed substrate bonded to at least one surface of the thin organic film using an adhesive, and to an optical pickup device having the phase retardation plate. In the phase retardation plate and the optical pickup device using the same, a liner thermal expansion coefficient (L1) of the thin organic film, a liner thermal expansion coefficient (L2) of the adhesive and a liner thermal expansion coefficient (L3) of the fixed substrate satisfy a relationship of L1>L2>L3; and the thin organic film retards the phase of incident light with a wavelength in a range of 400 to 800 nm by π/2 or π, the thin organic film having a phase retardation value between 0 and π. Accordingly, there is provided a phase retardation plate and an optical pickup device using the same, wherein fixation between materials is securely kept against a change in temperature over a long period of time, thereby improving reliability of products and obtaining a desired amount of phase retardation for incident light of a wide wavelength band.

摘要： The present invention relates to a direct methanol fuel cell having reduced methanol crossover, which comprises a layer of material for controlling the diffusion rate of fuel. More particularly, it relates to a direct methanol fuel cell in which the material for controlling the diffusion rate of fuel is interposed between an anode and a fuel reservoir or positioned within the fuel reservoir, and thus, the diffusion rate of methanol is reduced even when using high concentration methanol fuel, such that the injected methanol is completely reacted in a catalyst layer so as to fundamentally reduce unreacted methanol, thereby suppressing the methanol crossover phenomenon and exhibiting high power density. In the inventive direct methanol fuel cell, the diffusion rate of fuel is controlled using the fuel diffusion rate-controlling material so as to suppress the methanol crossover phenomenon, thereby increasing energy density and output density. Also, since a high methanol concentration of aqueous methanol fuel is used in the inventive fuel cell, the fuel cell can be used for a long period of time even with a small amount of fuel, and the volume of the fuel reservoir can be reduced, thus making it easy to miniaturize the fuel cell. According to the invention, the performance of all kinds of direct methanol fuel cells can be improved and the fuel cells can be used as electric power sources for small-sized portable electronic products, such as portable phones, PDAs, and notebook computers.
摘要翻译：本发明涉及具有降低的甲醇交叉的直接甲醇燃料电池，其包括用于控制燃料扩散速率的材料层。更具体地说，本发明涉及一种直接甲醇燃料电池，其中用于控制燃料扩散速率的材料介于阳极和燃料容器之间或者位于燃料储存器内，因此即使当甲醇燃料电池的扩散速率使用高浓度甲醇燃料，使得注入的甲醇在催化剂层中完全反应，从根本上减少未反应的甲醇，从而抑制甲醇交叉现象并表现出高的功率密度。在本发明的直接甲醇燃料电池中，使用燃料扩散速率控制材料控制燃料的扩散速率，以抑制甲醇交叉现象，从而增加能量密度和输出密度。此外，由于在本发明的燃料电池中使用高甲醇浓度的甲醇水溶液，所以即使使用少量的燃料也能够长时间使用燃料电池，并且可以减少燃料容积的体积，从而容易使燃料电池小型化。根据本发明，可以提高各种直接甲醇燃料电池的性能，并且燃料电池可以用作便携式电话，PDA和笔记本电脑等小型便携式电子产品的电力来源。

摘要： An optical scanning unit with a rotatable hologram disc, including a light source, a rotatable hologram disc provided with a plurality of holograms, the holograms being formed concentrically along a radial direction to diffract a beam emitted from the light source by multiple steps, a reflecting member that reflects the beam emitted from the light source and diffracted by one of the holograms into another hologram, and a fixed hologram correcting the diffracted beam incident through the rotatable hologram disc to focus it on a scanning object. In the optical scanning unit, the light passes through the plurality of holograms formed along a radial direction of the rotatable hologram disc so that a scan width can be extended without reducing a scan speed of the optical scanning unit.
