摘要:
An organic electronic device. The device includes a first electrode to inject or extract hole, the first electrode including a conductive layer and an n-type organic compound layer disposed on the conductive layer, a second electrode to inject or extract electron, a p-type organic compound layer disposed between the n-type organic compound layer and the second electrode. The p-type organic compound layer forms an NP junction between the n-type organic compound layer and the p-type organic compound layer. The energy difference between a lowest unoccupied molecular orbital (LUMO) energy of the n-type organic compound layer and a Fermi energy of the conductive layer is about 2 eV or less, and the energy difference between the LUMO energy of the n-type organic compound layer and a highest unoccupied molecular orbital (HOMO) energy of the p-type organic compound layer is about 1 eV or less.

摘要:
A structural element reinforced with composite materials comprises: a core part in a shape of an article and with sharp edges or corners rounded off, the core part having a first external surface forming about one half of an entire external surface of the article, the core part further having a second external surface forming about the other half of the entire external surface of the article; a first reinforcing cloth adhered on the first external surface of the core part, the first reinforcing cloth containing resin and reinforcing particles or fibrous materials; and a second reinforcing cloth adhered on the second external surface of the core part, the second reinforcing cloth containing resin and reinforcing particles or fibrous materials. A method of producing the structural element is also disclosed, in which the external surface of the structural element is divided into two surfaces (i.e., first and second external surfaces), and a reinforcing fiber cloth are securely attached on each external surface one after another, by application of vacuum pressure on a resilient backing film covering a reinforcing cloth for attaching.
摘要:
The present invention relates to a transformed lymphokine activated killer cell (I-LAK cell) useful in the treatment of cancer or virus infection into which a recombinant vector carrying IL-2 gene to which it is operably linked is introduced. Also it relates to a pharmaceutical composition for treating cancer or virus infection disease comprising a sufficient amount of I-LAK cell to elicit an immune response.
摘要:
A device for controlling belt lubrication and cooling of a CVT (Continuously Variable Transmission) is improved for minimizing fluid consumption and improving cooling efficiency by changing the nozzle spraying direction for belt lubrication and cooling. The device for controlling belt lubrication and cooling of the CVT (Continuously Variable Transmission) comprises a fluid control portion operated by flowing of a fluid pressure supplied to a primary pulley and a secondary pulley, and a fluid supply portion for controlling a predetermined fluid supply according to movement of the fluid control portion and being connected to the same.
摘要:
A parking brake apparatus for an automatic transmission vehicle in one embodiment includes a parking shaft connected to a shift lever, a cam plate secured to the parking shaft, a parking rod assembly operated when the cam plate secured to the parking shaft rotates through manipulation of the shift lever, and a parking gear meshed with a sprag which is actuated by the parking rod assembly. The apparatus comprises a driving section having a driving motor assembly for driving the parking shaft such that the sprag can be engaged with or disengaged from the parking gear when the shift lever is manipulated between P and R, and operating to ensure that a rotational force of a driving motor is added to a disengaging force of the parking rod assembly for disengaging the sprag engaged with the parking gear when the disengaging force is insufficient.
