Abstract: PURPOSE:To generate an output data of a prescribed rate in the frame unit and to attain efficient compression by providing a cosine conversion circuit, a block processing circuit and a buffering circuit so as to apply coding. CONSTITUTION:An input digital signal is subject to 2-dimension cosine conversion by a cosine conversion circuit 2 and a coefficient table corresponding to a block size is obtained. Moreover, a block processing circuit 3 applies block pressing again and a coefficient table is converted into a signal consecutive for each block being the unit of coding. The output signal is fed to maximum/ minimum detection circuits 4, 5 and a subtractor circuit 6, from which a dynamic range DR represented by an equation of maximum value - minimum value = DR is obtained and fed to a buffering circuit 11. The circuit 11 obtains threshold values T1-T4 whose transmitted data rate is constant and a parameter code Pi corresponding to the threshold value is outputted. Thus, since the block of the coefficient table whose range DR is decreased is subject to high efficient coding, the highly efficient compression and output data generation of a constant rate are attained.

Filed: 1997-10-03
Abstract: PROBLEM TO BE SOLVED: To surely realize communication to which real time ability is requested by preferentially transferring an Ethernet frame to which a specified virtual LAN number is added compared to the other frames. SOLUTION: It is assumed that a switching hub 10 simultaneously receives the Ethernet frames 11 and 12 addressed to a terminal 15 from a terminal 14 and a terminal 16. The switching hub 10 recognizes that the terminal 14 and the terminal 15 belong to virtual LAN number =1 and the terminal 15 and the terminal 16 to a virtual LAN number = 2. At that time, the switching hub 10 transfers the Ethernet frame 11 to which the virtual LAN number = 1 with high priority is added to the terminal 15 and transfers the Ethernet frame 12 to the terminal 15. When the number of the received Ethernet frames exceeds the maximum processing ability of the switching hub, the switching hub 10 transfers the Ethernet frame 11 to the terminal 15 and cancels the Ethernet frame 12.

Title: Method for processing semiconductor substrate
Inventor: SUGINO SHIGEYUKI
IPC: H01L21/205
Filed: 1984-12-21
Abstract: PURPOSE:To enable efficient processing and reduce adverse effect to the environment by performing the deposit process or etching process while exposing the deposit surface or etching surface on a semiconductor substrate to a light of the resonant line of the same substance as the deposit material or the material to be etched. CONSTITUTION:The deposit process or etching process is performed while the deposit surface on a semiconductor substrate 2 or the etching surface on the semiconductor substrate is exposed to a light of the resonant line of the same substance as the deposit material or the material to be etched. For instance, when a silicon layer is epitaxially grown, the surface to be processed is exposed with a hollow cathode lamp 5 having a cathode 52 made of a silicon material. Optical energy of the resonant line from the same substance as the material to be processed is most effective for energy excitation of the material to be processed, and it thus gives least effect to the environment within a device. In other words, deposit and etching can be performed with the environment being kept at the lowest temperature.
