Abstract:
A antenna module comprises various different single-band miniature antennas respectively coupled to and hid inside individual batteries, and each antenna shares original terminals of the individual battery; the antenna module is allowed to use the terminals to electrically connect to a main body of a wireless communication device to enable the individual antenna module to receive signals in a different frequency range and the wireless communication device to be unnecessary to be disposed with various different single-band antennas. Whereby, space for original disposition of various different single-band antennas can be saved for the disposition of other components.
Abstract:
A light guide includes a main body and a curved refracting face formed in the main body. As light enters the main body, a bright zone and a secondary bright zone less brighter than the bright zone are formed in the main body. The curved refracting face can be an inner wall face of a curved groove or a cavity disposed in the main body. Through the formation of the curved refracting face, the light in the secondary bright zone can be directed such that, when the light guide is disposed in a thin film keyboard, the brightness of a portion of the keyboard that corresponds to the secondary bright zone has improved brightness.
Abstract:
An ink cartridge has a container, an air valve, and a floating ball. The container is utilized for storing ink. The container has at least an air channel and a flow path. The air valve is disposed at the air channel for preventing the ink from being outside the container via the air channel. The floating ball has density smaller than that of the ink. As the ink in the container is below a predetermined height, the floating ball blocks the flow path permanently.
Abstract:
An ink ejection system with a print head and an ink priming station is provided. The ink reservoir of the print head has a plurality of ink channels, a plurality of ball valves, a plurality of storing areas, and a plurality of priming holes. Each of the ball valves is located at an outlet of the respective ink channel and has a floating ball. The plurality of storing areas is aligned to the plurality of ink channels respectively for storing ink of different colors. The plurality of priming holes, which are located on a surface of the ink reservoir, is connected with the respective storing areas for balancing air pressure between interior of the ink reservoir and environment. As ink in the storing area excesses a predetermined height, the respective floating ball closes the respective ball valve to stop injecting ink to the respective storing area. The ink priming station has an air cover linked to a pump. As the print head is stationed on the ink priming station, the air cover covers the priming holes to have the interior of the ink reservoir showing negative pressure.
Abstract:
A container for storing semiconductor devices is revealed. The container includes a receiving body, a seal plate, and a cover. At least one fastener and at least one driver are mounted in the receiving body. The seal plate is fastened under the receiving body and against the driver so as to fix the driver on the receiving body. When the driver is rotated, the fastener is driven to move in the receiving body by the driver. At least one fixing part of the fastener is moved toward at least one fastening part of the cover. By the fixing part locked in the fastening part, the cover is fixed on the receiving body. Thus a force opposite to the rotating shaft will not be generated around a periphery of the driver. Therefore stability of the rotating driver is improved and the container is opened and closed smoothly.
Abstract:
A container for storing semiconductor devices is revealed. The container includes a receiving body and a cover. The receiving body is disposed with at least one fastener and at least one driver therein. The fastener includes a rolling element that is in contact with the driver. When the driver is rotated, it drives the fastener to move in the receiving body. At least one fixing part of the fastener is moved toward at least one fastening part of the cover. The cover is fixed on the receiving body by the fixing part locked in the fastening part. Moreover, friction between the fastener and the driver is minimized by the rolling element which reduces contact area between the fastener and the driver so as to prevent production of contaminants in the container and protect semiconductor devices stored in the container from being polluted. Thus the container is of high cleanness.
Abstract:
A switch structure on the sidewall of a circuit board for an electronic device and manufacturing methods of the circuit board are provided. The switch structure includes a circuit board, a plurality of conductive portions, and a movable unit. The conductive portions are formed on a sidewall of the circuit board and electrically insulated from each other. The movable unit is disposed corresponding to the conductive portions to electrically connect or disconnect the plurality of conductive portions to achieve the switch function. The switch structure utilizes the structural design of the circuit board to reduce the space on the circuit board preserved for a circuit board switch.
