Abstract:
The present invention relates to a manufacturing method for a PDMS microchannel for an immunosensor, which uses a mixed mold of glass bead-SU8 instead of the existing SU8 mold. The manufacturing method for a microchannel is implemented by the same process as the existing SU8 mold manufacturing process except the use of a glass bead-SU8 mixture instead of SU8 and plasma processing on a wafer, and does not add any complex process for transforming the inner surface of a microchannel. In addition, the manufacturing method for an immunosensor can have a large surface area in order to efficiently fixate an antibody, and can obtain a PDMS microchannel having a surface with high hydrophobicity. The microchannel can be utilized as an immunosensor by effectively fixating protein particles therein.
Abstract:
The purpose of the present invention is to provide a folding bicycle frame which has a front body with a front wheel inserted in a gap of a rear wheel of a rear body and overlapped with the rear wheel to form a round shape, minimizes a storage space compared with conventional bicycle frames, and improves user convenience. The folding bicycle comprises: a pair of rear wheels which are mutually connected across a stay unit; a front wheel, which is rotatably supported by forks, provided on the lower side of a handle; a folding unit for connecting and supporting the front and rear wheels. The folding unit includes: a second under tube which is rotated by a rear under folding joint, connected to the stay unit, and folded in between the rear wheels; a first under tube which is rotated by a lower unfolding joint, unfolded by being connected to the stay unit, and connected to and fixed on the upper end of the fork by a head tube; and a top tube which si rotated by a rear top folding joint, connected to the stay unit, folded in between the rear wheels, and detachably connected to the first under tube by an detaching joint.

PURPOSE: A method for tuning a glass antenna is provided to improve the work efficiency of tuning by extracting a suitable direction and size to obtain a gain. CONSTITUTION: In a method for tuning a glass antenna, the structures sensitivity of a designed glass antenna is analyzed through a simulation tool(S1). A priority is determined according to the size of a gain by using the data analyzing the sensitivity(S2). A specific frequency is selected from a tuning frequency (S3). A tuning process is operated according to the priority (S4). It is determined whether a gain in an another frequency not a specific frequency is lower than a reference value or not(S5). The tuning process is interrupted in the specific frequency (S6). The other specific frequency is selected from the tuning frequency.
Abstract:
A radical acceleration preventive device for a vehicle is provided to effectively prevent radical acceleration of the vehicle by controlling an ECU to instantly interrupt power supply to a driving system that comprises an electromagnet relay. A radical acceleration preventive device for a vehicle comprises a driving part(10), a throttle wire(20), a connection point sensing member(30), and an ECU. The driving part is integrally mounted with an accelerator pedal(1). The throttle wire is separably connected to the driving part, to determine an opened angle of a throttle valve according to operative force of the accelerator pedal. The connection point sensing member is connected to one end of the driving part to detect whether the driving part is connected or separated with respect to the throttle wire. The ECU controls the driving part in order to prevent radical acceleration, based on a signals transmitted from the connection point sensing member, a throttle position sensor(41), and a front distance sensor(42).
