Abstract:
A light source device and a light source system using the same are provided. The light source device includes a lens and a light source disposed under the lens. The lens has a light-emitting top surface and a bottom surface having a hole that is surrounded by an inner wall surface and an inner top surface. The inner top surface and a projection area of thereof onto the light-emitting top surface are flat surfaces. The light source has an illumination area, wherein an opening of the hole covers a projection area of the illumination area onto the bottom surface. The light source system includes a plurality of the light source device disposed in a honeycomb arrangement, wherein the light source devices are spaced apart from each other.
Abstract:
A heat dissipation device is used in a circuit board, where the circuit board includes a chip and at least one positioning hole disposed around the chip, and each of the positioning holes has a bare metal area on its periphery. The heat dissipation device includes a heat dissipation element, a conductive element and at least one fixing part. The heat dissipation element is disposed on the chip; the conductive element is connected electrically to the bare metal area of the circuit board and the heat dissipation element respectively; the fixing part passes through the fixing holes and is connected to the positioning hole, so as to fix the heat dissipation element to the circuit board. A circuit board is also provided, which includes a substrate, a chip, a positioning hole and the heat dissipation device.
Abstract:
Cholesterol inhibitor produced by Monascus, monacolin k, is a secondary metabolite of polyketides. The invention provides probes specific to monacolin k biosynthesis gene cluster. BAC clones having putative monacolin k gene cluster were screened from BAC (bacterial artificial chromosome) library, and sequencing and annotation were performed on these clones. The results show that 2 polyketide synthase (PKS) genes and 7 regulatory genes related to monacolin k synthesis were obtained. Full-length cDNAs of these genes were then obtained by RT-PCR and cloned to expression vectors for the expression of these genes.
