High-Power (over 100 mW) Green Laser Diodes on Semipolar {2021} GaN Substrates Operating at Wavelengths beyond 530 nm

Abstract: Continuous-wave operation of InGaN green laser diodes (LDs) on semipolar {2021} GaN substrates with output powers of over 100 mW in the spectral region beyond 530 nm is demonstrated Wall plug efficiencies (WPEs) as high as 70–89% are realized in the wavelength range of 525–532 nm, which exceed those reported for c-plane LDs The longest lasing wavelength has reached 5366 nm under cw operation These results suggest that the InGaN green LDs on the {2021} plane are better suited as light sources for applications requiring wavelengths over 525 nm

Transmission recording and reproduction of digital data and time information in transport packets using a compression ratio

Abstract: A data packet which contains time information is time compressed and the time information is extracted from the time compressed data packet. A system clock is synchronized with the extracted time information and is multiplied by a predetermined compression ratio to produce replacement time information which replaces the time information in the time compressed data packet. The time compressed data packet that now contains the replacement time information is modulated and transmitted or recorded.

Communication system and method

Abstract: The present invention relates to communication systems and methods which allow the partner of communication to be easily specified. A portable telephone 52 is provided with a non-contact IC card which communicates with a reader/writer of a personal computer 51 by electromagnetic waves. When the non-contact IC card receives electromagnetic waves emitted by the reader/writer, the portable telephone 52 reports the card ID assigned to the non-contact IC card to the personal computer 51. The card ID includes the Bluetooth address of the portable telephone 52. When the personal computer 51 obtains the Bluetooth addresses of the portable telephone 52 and a PDA 53 at an inquiry, the personal computer 51 specifies the portable telephone 52 as a Bluetooth device with which synchronization is established, according to the Bluetooth address reported in advance. The present invention can be applied to information processing apparatuses such as personal computers and portable telephones.

Computerized system for managing preparation and prosecution of applications in various countries for protection of industrial property rights

Abstract: A computerized system for managing preparation and prosecution of applications for protection of industrial property rights in various contries includes a data memory which stores a rule data for controlling input, output and internal operation of the system. The rule data includes information concerning required actions at each step of prosecution of applications in each country when the applications are filed. Such rule data is so designed as to provide proper guidance to the operator for guiding proper entry of input data in order to avoid error in operation. Preferably, the rule data consists of common rule data components which are commonly applicable for applications in any country and local rule data components which are specifically applicable for a specific country.

Active matrix display and active matrix organic electroluminescence display

Abstract: An active-matrix display device employs current-programmed-type pixel circuits and performs the writing data to each of pixels on a line-by-line basis The active-matrix display device having a matrix of current-programmed-type pixel circuits includes a data line driving circuit 15 formed of m current driving circuits (CD) 15 - 1 to 15 -m arranged corresponding to respective data lines 13 - 1 to 13 -m The data line driving circuit (CD) 15 - 1 to 15 -m holds image data (luminance data herein) in the form of voltage, and then converts the voltage of the image data into a current signal The current signal is then fed to the data lines 13 - 1 to 13 -m at a time The image information is thus written on the pixel circuits 11
