Abstract:
Included herein is an instrument component for mounting to the body of an instrument having strings, for example a guitar. The instrument component comprises a plurality of attachment devices, an elongated bracket, and a biasing element. The elongated bracket includes a plurality of attachment apertures where each aperture includes a center and is shaped to accept one of the attachment devices. A biasing element is positioned in each attachment aperture wherein each biasing element engages one of the attachment devices. Each biasing element includes a plurality of protrusions wherein each protrusion biases the attachment device toward the center of the attachment aperture.
Abstract:
A streamer discharge type lightening rod is disclosed, which is capable of generating lots of ions so that a certain object can be effectively protected from lightening in such a manner that an induction current is formed using ions in the air as thundercloud is formed, and ions having polarities corresponding to the ions in the air are greatly generated at a surface of the lightening rod, and a streamer by a corona discharge is increased at a surface of the thundercloud for thereby inducing lightening from a thundercloud similar to when lightening is naturally generated.
Abstract:
An explosive bolt includes: a bolt body forming a receiving space therein; a pressure transmitting means received in the receiving space of the bolt body; a pressure generating means connected to the pressure transmitting means and generating pressure; and a cut portion formed at the bolt body and cut upon receiving pressure generated from the pressure generating means through the pressure transmitting means. Accordingly, the amount of gunpowder used is minimized, and a position of a cut portion can be freely designed and fixed, thereby not only minimizing explosion impact and noise but also improving productivity and reliability.
Abstract:
An apparatus includes a transfer unit under an atmospheric condition and having a robot therein; and at least one process chamber connected to one side of the transfer unit with a slot valve there between, and being alternately under a vacuum condition and under an atmospheric condition.
Abstract:
A cylindrical storage electrode in a semiconductor device is manufactured by forming a contact hole in a poly oxide film and by forming a first thin film on the film and in the hole. Next, a core oxide film and an anti-reflective coating film are formed on the first thin film to determine the height of the cylinder. A pattern is then formed by etching the anti-reflective coating film, core oxide film and the first thin film such that the poly oxide film is exposed. A second thin film is formed on the overall resultant structure, and a tungsten silicide layer is formed on the second thin film. Inner and outer walls of the cylinder are then formed by blanket-etching the tungsten silicide film and the second thin film such that the core oxide film is exposed. After the core oxide film is removed, a selective metastable polysilicon (SMPS) process is performed so that different grain growths are generated at the inner and outer walls of the cylinder. A storage electrode is then formed by annealing the cylinder. By depositing an amorphous silicon film on the inner wall of the cylinder-type capacitor and Si-rich tungsten silicide film on the outer wall, the surface area of the inner wall expands through normal SMPS and a rugged tungsten silicide film is formed on the outer wall. Spacing between cells is preserved, while generation of a bridge is prevented.
Abstract:
Disclosed are a cathode material for a secondary battery, and a manufacturing method of the same. The cathode material includes a lithium manganese phosphate LiMnPO4/sodium manganese fluorophosphate Na2MnPO4F composite, in which the LiMnPO4 and Na2MnPO4F have different crystal structures. Additionally, the method of manufacturing the cathode material may be done in a single step through a hydrothermal synthesis, which greatly reduces the time and cost of production. Additionally, the disclosure provides that the electric conductivity of the cathode material may be improved through carbon coating, thereby providing a cathode material with excellent electrochemical activity.
