摘要： An amount of a semiconductor substrate cut due to etching in the bottom of a contact hole formed by the SAC technique is reduced. Silicon oxide films are dry etched under the conditions of increasing the etching selective ratio of the silicon oxide films to an insulating film. Then, the conditions are changed to those increasing the etching selective ratio of the insulating film to the silicon oxide films and the insulating film is etched by a predetermined amount.

摘要： An asynchronous transfer mode type multimedia radiocommunication system including a transmitter and a receiver connected to the transmitter via an asynchronous transfer mode network and wherein accesses to two channel data which communicate by radio and have different levels of communication quality, are performed by the asynchronous transfer mode network. A separator of a transmitter separates input data into L-bit main channel data and one-bit sub channel data. A convolutional coder convolutionally codes the data. Further, a mapper maps the resultant binary information onto crossed I and Q channel axes according to the data by switching for each L bit of the main channel data, thereby enabling transmission of additive information corresponding to data of 1/L the transfer rate. Thereafter, a viterbi decoder of a receiver decodes the information. Further, a sub channel having arbitrary communication quality can be provided by arbitrarily selecting the value (L.sub.min .ltoreq.L) of an L bit.

摘要： A differential circuit configuration for generating an inverted signal and a non-inverted signal of an original signal is presented. The waveforms of the output signals are highly synchronous and precise owing to the circuit design which provides matched gate-to-source voltage vs drain-to-source current to produce output trace matching in the output voltage traces of a pair of pull-up transistors with a pair of pull-down transistors. The circuit configuration does not require adjustable capacitors or driving circuits, and is therefore suitable for use in advanced compact devices.

摘要： A micro computer 6 reads a manual switch signal Sm from an operating section 15, and sets a target output W0 of an electrically driven compressor 11 based on the manual switch signal Sm. A temperature sensor 20 detects a temperature Ts of a designated component in the compressor control system. Micro computer 6 judges whether the detected temperature Ts is larger than a predetermined upper limit Ta, and generates an output command W equalized to the target output W0 when the temperature Ts is within a predetermined allowable range. On the other hand, when the detected temperature Ts is higher than the upper limit Ta, micro computer 6 sets a modified output W1 smaller than target output W0 by a predetermined correction value .DELTA.W (W1=W0-.DELTA.W>0), and adjusts the output command W to the modified output W1. Then, the compressor 11 is actuated based on thus obtained output command W.
