Abstract:
A carrying structure of semiconductor includes a carrier made of a plastic material with a heat conduction region, each surface of the carrier has an interface layer formed on, and an electrically insulation circuit and a metal layer are defined on the interface layer. The insulation circuit is located on the surface of the heat conduction region and on an encircling annular region extended from two surfaces of the heat conduction region, and at the same time exposing parts of the carrier surface thereby splitting the metal layer on the interface layer into at least two electrodes. A thermal conductor formed in the heat conduction region has a LED chip adhered on it which has at least a contact point connected with the corresponding metal layer with a metal wiring so as to dissipate the heat generated by the chip rapidly with the thermal conductor.

Each connecting component has a base and a constraining wall, and the base is engaged and electrically connected to corresponding connecting portion by concavo-convex engagement or screwing, and the conducting wire is fastened by clamping of the constraining wall for adjusting or welding conveniently, so that the stator and the rotor can connect electrically.
Abstract:
A vehicle lamp has a lamp holder, an LED array, an interior heat sink and a heat exchanger. The lamp holder is hollow and has a heat conductive portion. The LED array is mounted in the lamp holder. The interior heat sink is mounted on the LED array and has an inner conductor attached between the LED array and the heat conductive portion. The heat exchanger is mounted on an outer side of the heat conductive portion. Therefore, the vehicle lamp can efficiently dissipate heat generated by the LED array by the interior heat sink and the heat exchanger with little or no dust entering the lamp holder and accumulating on the LED array for improved lifespan and constant heat dissipating performance.
Abstract:
A ball screw comprises a shaft, a nut, two return elements, plural rolling elements and a sleeve. When being rotated, the shaft will drive the nut to move and circulate the rolling elements within a circulation path defined by a loaded path and the return passages of the return elements. The nut is provided with a circular groove in an outer circumferential surface thereof, and the sleeve is disposed in the circular groove. The sleeve is provided with plural push grooves in an inner circumferential surface thereof, and there is an angular difference between a rolling passage in the nut and the respective push grooves, and the push grooves cooperate with the rolling elements which pass through the rolling passage. By such arrangements, the push grooves of the sleeve will be pushed by the rolling elements to convert the linear motion into rotary motion, thus making the sleeve rotate.
Abstract:
A rotary micro-adjustment mechanism for a synchronous double-drive positioning platform (such as a gantry) is disposed between a beam and support pillars of the synchronous double-drive positioning platform and comprises a positioning pillar and elastic members. The positioning pillar is provided to pivot the beam relative to the respective support pillars to compensate displacement error of the beam and the support pillars. The elastic members are provided to resist the pivotal rotation between the beam and the support pillar by their restoring force, so as to improve the rigidity of the overall mechanism.
Abstract:
A method for making a test fixture includes the following steps. A Linux operating system is installed to a computer storage device and a test program is installed to the storage device. Which kernels have been installed in the Linux operating system is checked to obtain a check result. A part of or entire content of the storage device is copied to a system image file except a boot file. A boot file directory structure is made in the system image file. The boot file in the storage device is customized to make a disc boot file in the boot file directory structure. The check result is recorded in the disc boot file. An initrd file corresponding to the check result is created in the boot file directory structure according to the boot file in the storage device. A bootable test disc is made using the system image file.
Abstract:
An electronic device includes a base, an intermediate member and a lens. The base includes a guiding portion, and a first, second and third connecting portions. The intermediate member includes a first, second and third engaging portions connected to the first, second and third connecting portions, respectively. The lens is disposed at a predetermined position via the intermediate member. When the first engaging portion situated in a first position is connected to the first connecting portion, the intermediate member has at least two degrees of freedom. When the intermediate member is positioned at a second position from the first position by the guide of the guiding portion, the second and third engaging portions are connected to the second and third connecting portions, wherein the intermediate member has zero degree of freedom, and the lens is disposed at the predetermined position via the intermediate member.
