Abstract: A fixing structure for fixing a seat of a vehicle includes a fixing member which includes a locking section, a buffering section and a restricting section. The locking and restricting sections are provided with a thread for meshing with the thread of the locking passage, and the buffering section has no thread. The fixing seat includes a locking passage and a restricting space connected to the locking passage. The locking member is inserted through the cover and screwed into the fixing seat. When vibrations occur, the locking member will be unscrewed from the locking passage. However, in order to prevent the locking member from fully disengaging from the fixing seat, the buffering section is retained in the restricting space to prevent the thread of the restricting section from meshing with the thread of the locking passage, which prevents disengagement of the locking member in a vibrating condition.

Abstract: A desk assembly includes a desk top pivotably connected to a seat or the armrest of the seat, and includes an angle adjustment unit and a positioning portion. The desk top is flat and suitable for books or magazines put thereon. A rack is pivotably connected to the desk top and has a positioning unit. The rack is pivoted and positioned relative to the desk top so that the board-like electronic device such as cellular phone or board-like computer can be supported on the rack.

Abstract: A seat unit includes a seat and a dining board is slidably and pivotably connected to the back of the backrest of the seat. A display device such as a flat-board computer, a table PC, or an In-Flight Entertainment device, is connected to the bottom face of the dining board. The dining board is connected with two links which are pivotably connected to the legs of the backrest so that the dining board is pivoted and positioned horizontally. The dining board has operation members on two sides thereof so as to be slidably engaged with grooves in the reception member on the backrest. The dining board can be slid and stored in the reception member and the passenger behind the backrest can operate and enjoy the In-Flight Entertainment device.

Abstract: A non-contact substrate chuck applies to sucking a substrate and comprises a first plate-like element, a second plate-like element paralleled the first plate-like element and a sucking element, wherein through holes of the first plate-like element and the second plate-like element jointly form a channel where the sucking element is accommodated. The chuck lets gas flow through a gas inlet of the sucking element toward the substrate to form a gap between an active surface of the substrate and a first surface of the first plate-like element. At least one side of the substrate is positioned by positioning protrusions of the first plate-like element. A least possible number of supporting points are used and arranged around the sides of the substrate without touching the substrate surface to prevent the substrate surface from being damaged. The present invention also discloses a vertical-type substrate supporting apparatus using the abovementioned chuck.

Abstract: A charging circuit includes a battery pack having a plurality of serially connected batteries and being connected to a power supply; a changeover switch being serially connected to and between any two adjacent batteries; and a precision voltage detector being parallelly connected to each of the batteries for independently detecting a voltage of the connected battery and sending out a detected result to a charging control circuit for controlling the ON/OFF of the changeover switch corresponding to the battery. When a battery is detected by a corresponding precision voltage detector as having been fully charged, the corresponding charging control circuit sets the changeover switch corresponding to the battery to OFF to stop charging the battery. The remaining batteries that are subsequently fully charged are disconnected from the power source one by one until all the batteries in the battery pack have been fully charged. Thus, all the batteries are balance-charged.

Abstract: In a method of charging batteries, a microcontroller and a series divider resistor are used to control the level of a charge current source supplied from a power supply, so that a plurality of serially connected batteries in a battery pack could be best charged. The microcontroller detects a voltage value of the battery pack via the series divider resistor. When all the batteries in the battery pack have been charged in a first charging cycle, the microcontroller controls the power supply to lower the output charge current and to charge the batteries in a second charging cycle, until the charge has been cycled a preset number of times. As a result, all the serially connected batteries in the battery pack are best charged.
