Abstract:
A bottle cap that is an apparatus for containing heterogeneous materials, applied in the discharge direction of materials in a container, comprises: a main body coupled to a bottle neck; and a containing unit assembled inside the main body with a storage space. An activated unit is assembled in the center of the upper support unit of the main body. An activation unit for downward movement is coupled to the activated unit so that the activated unit may move downward by a separate activation unit. An opening/closing unit is coupled with the lower part of the activated unit with the above structure in order to seal an opening/closing hole of the storage space.

Abstract:
In a process for manufacturing a hyperfine semiconductor device, an apparatus for manufacturing a semiconductor device such as a schottky barrier MOSFET and a method for manufacturing the semiconductor device using the same are provided. Two chambers are connected with each other. A cleaning process, a metal layer forming process, and subsequent processes can be performed in situ by using the two chambers, thereby the attachment of the unnecessary impurities and the formation of the oxide can be prevented and the optimization of the process can be accomplished.
Abstract:
A cap with a storage space for containing a secondary material includes a storage portion having a storage space and provided with a seal plate formed on a lower end of the storage space, an outer cap foldably formed on the storage portion and coupled to a spouting portion, a spouting member inserted in the spouting portion, and an operational member for breaking the seal plate when the spouting member is operation.
Abstract:
A Schottky barrier tunnel transistor includes a gate electrode, and source and drain regions. The gate electrode is formed over a channel region of a substrate to form a Schottky junction with the substrate. The source and drain regions are formed in the substrate exposed on both sides of the gate electrode.
Abstract:
An speed sensor for a rotating shaft includes a plurality of magnetic portions on the shaft that output a magnetic field from each of the magnetic portions, wherein the magnetic portions are integrally formed in the shaft by magnetically polarizing the shaft material itself. At least one magnetic field sensor is positioned proximate to the shaft for detecting the magnetic field from each of the magnetic portions and for outputting a signal corresponding to the angular speed of the shaft as the shaft rotates. The signal is useful for calculating the angular speed of the shaft, and the calculated angular speed value is useful for things like adjusting the angular speed of the shaft, monitoring the performance of the system in which the shaft is used, and for other purposes.
Abstract:
A cap assembly having a storage chamber for a secondary ingredient, which is adapted to a mouth of a container, comprising: a body having a mouth; a chamber part having a storage space for secondary ingredient in the body and a hole formed at the lower end thereof; said chamber part is sealed by a movable working member and is opened when the movable working member is removed from the hole upon removing the cap so that the secondary ingredient may be mixed with the first ingredient in the container, said the movable working member being adapted to maintain the opened hole, after moving to open the hole, thereby effectively mixing of the different ingredients.
Abstract:
The storage chamber for secondary material applicable to the discharging direction of contents stored in the container consists of body with storage space and inseparable operating section mounted around the globe. If above operating section moves up, opening and closing hole made or formed in the storage space of storage is opened and contents stored in the storage space is dropped and mixed with contents stored in the container. The mixed contents are discharged via a vent mounted on the top of operating section. A vent is not opened until the operating section is opened, and closing section of opening and closing hole is provided so that the opening and closing hole may not be not clogged after being opened.
Abstract:
Provided are a field effect transistor and a method of fabricating the same, wherein the field effect transistor is formed which has a hyperfine channel length by employing a technique for forming a sidewall spacer and adjusting the deposition thickness of a thin film. In the field effect transistor of the present invention, a source junction and a drain junction are thin, and the overlap between the source and the gate and between the drain and the gate is prevented, thereby lowering parasitic resistance. Further, the gate electric field is easily introduced to the drain extending region, so that the carrier concentration is effectively controlled in the channel at the drain. Also, the drain extending region is formed to be thinner than the source, so that the short channel characteristic is excellent.
Abstract:
Provided is a method for selectively functionalizing unmodified solid surface, not oxidized and nitrified, into an aldehyde group, and a method for immobilizing an active material such as bio material or functional material on the functionalized aldehyde solid surface through strong and stable chemical bonding. Differently from a conventional method immobilizing deoxyribonucleic acid (DNA) using a cross linker, the method of the present invention does not require a cross linker reaction step to thereby shorten a process. Also, since a cross linker is absent, the monomolecular layer on the surface of a device is thin, which reduces a perturbation effect by molecular layer. This is useful in fabrication of molecular electronic devices and bio-active devices. In addition, since the bio material or functional material is selectively immobilized only on the unmodified surface, the present invention can functionalize only a specific solid surface and develop a highly sensitive sensor and an improved functional device.
