On a silicon substrate, a silicon oxide layer, a first platinum layer, a dielectric film and a second platinum layer are formed, and then the second platinum layer and the dielectric film are dry etched, via a resist layer, in a 1-5 Pa low pressure region with a mixed gas of HBr and O2 as the etching gas. As soon as the first platinum layer is exposed, the unetched portion of dielectric film is et...

An insulating film is formed on the surface of the base of a semiconductor, and a portion of the insulating film is removed to cause the surface to appear outside. The exposed surface is terminated with hydrogen, and then energy beams are applied to selectively remove the terminating hydrogen. Metal is selectively deposited on the portion terminated with left hydrogen atoms.

A binary connector intercouples a plugged drug vial and a plugged, flexible-walled diluent container so that the diluent can pass to the vial from the container only after the latter has been pressurized by squeezing. Sharp-tipped, hollow spikes with intercommunicating axial bores extend in diametrically opposite directions from a disk-shaped base, with jaws having circularly arrayed flexible arms...

A fixed-length signal is retrieved from a bitstream comprising one or more variable-length encoded signals. A variable-length encoded signal of the bitstream is decoded to generate a decoded signal corresponding to the fixed-length signal by accessing one or more tables in accordance with the fixed-length signal to retrieve a contribution, an input pointer flag, an output pointer flag, and a next ...

In a video communication system including a sending terminal and a receiving terminal connected via a packet switching network, a receiving terminal which has detected loss of a video packet sets a video output into a freeze status and transmits a refresh request command to the sending terminal. Upon receiving the refresh request command, the sending terminal requests a video coder unit to execute...
