POSTER: computer news   ||   NICHIA BLUE-VIOLET LASER DIODE	DATE:2007-02-23
The Japanese company nichia corporation declared about the fact that it successfully completed the development of powerful blue-violet laser diode, which will make possible to attain the recording speed into 10x on two- and to 2x - to the four-layer disks of format from the following generation (HD DVD Blu-ray). The contemporary diodes, utilized in the present recorders of such sizes, emit light pulses with power in 130 mW, whereas in the development Of nichia this index is equal to 320 mW so high a power was achieved with the current strength in 260 mA and the voltage 5 v. the temperature of case diode did not exceed 80°C. In the course of tests the diode demonstrated stable work for the elongation of 1000 hours. Nichia speaks about the suppositional period of service of its solution in 10 thousand hours. The mass production of such diodes must begin in first half of 2008. This means that for the users on the market not later than the end of the following year can appear the high-speed drives, which record the disks HD DVD and Blu-ray. For this it would be however, increase rather well the service life of the service of such diodes. nichia blue-violet laser diode	Add Comment ( 0 ) NICHIA BLUE-VIOLET LASER DIODE

The producers of flash- memory in the near future can collide with the limitations, which will make further improvement of traditional technological process impossible. This limit, as it is considered now, can begin upon transfer n 3. - nm or 22- nm standard. However, Korean researchers, according to material, published nature nanotechnology, report that with the application of carbonic nano-tubes they succeeded in creating 10 nm of structure. In connection with this it is worthwhile to recall that already in the present year must appear the first commercial products 22- nm memory NRAM from production nantero, that is been based on the use of nano-tubes and making possible to attain greater performance during the smaller energy consumption, than in traditional DRAM. The described by Korean developers technology assumes that the new material, named the insulator Mott, whose distinctive ability the possibility of rapid switching between the states of conductor or dielectric is. The creators of technology assume that its introduction will make possible to fix the production of flash- memory with a capacity of 100 Gb and more. technology insulator Mott	Add Comment ( 0 ) TECHNOLOGY INSULATOR MOTT

Yesterday the company OCZ technology, noted for its high performance memory modules, presented this sequential product, PC 2-8500 Reaper HPC (Heat pipe conduit). Product is remarkable by, in the first place, its cooling system. Besides common for such modules aluminum scatterer of heat, the producer supplied his solution with the additional radiator, to which from the module conduct two thermal tubes. New memory will be sold in the complete sets of two pieces by summary volume in 2 Gb, intended for the work in dual-channel regime. The first modules DDR2 series reaper HPC, operate at frequency 1066 MHz with the latency 5-5-5-15 (CAS-TRCD-TRP-TRAS). Support technology enhanced performance profiles (EPP), which will facilitate overclock for the beginning enthusiasts and it will afford the additional possibilities of tuning system for the experienced users, and will also increase performance in the systems on the base chipsets  NVIDIA SLI. The service voltage of modules composes 2,1 v; however, producer resolution to the use of value 2,4 v ± 5% without the loss of guarantee, which, as usually in OCZ, is lifelong.

The company canon did not limit to the announcement rapid-firing SLR- camera EOS-1d mark III and uncommon photo- video camera powerShot TX1, but represented today two new budget camera series A  : PowerShot A570IS PowerShot a560. Let us recall, were very recently announced the lowest-end models of this series. Both new camera are equipped by 7,1-megapixel with 1/2,5- inch- sensors, by LCD- displays with the diagonal 2,5 inches (resolution 115 thousand pixels) and 4- by multiple zoom lenses, which make possible to overlap the range of equivalent focal lengths 35 - 140 mm with f/2,6 - f/5,5. Moreover, the model a570 IS, similar to the more expensive camera powerShot a710 IS, obtained the optical stabilizer of image. Both cameras are equipped with processors DIGIC III, which made possible to realize such update for A series of function as the technology of the recognition persons (Face detection technology), the automatic correction red eyes and the possibility of survey with the value of sensitivity ISO 1600. Furthermore, the survey of videot in the VGA- resolution is now accessible with frequency 30 frames per second. Besides the set of topical programs all manual tuning of parameters exposure are traditionally accessible to user. The electric power supply of cameras is achieved from two elements of the type AA. The cost Of canon powerShot a560 will be about 230 dollars, and for stabilized version with the index a570 IS will be 50 dollars more. canon powerShot a560-a570	Add Comment ( 0 ) CANON POWERSHOT A560-A570
