TL;DR: A substrate processing system is used to perform an exposure process of an organic film formed on a substrate in a gas atmosphere obtained by vaporizing an organic solvent solution for dissolving and reflowing the organic film.
Abstract: A substrate processing system which sprays exposure process gas onto a substrate disposed within a chamber. The substrate processing system is used, for example, for performing an exposure process of an organic film formed on a substrate in a gas atmosphere obtained by vaporizing an organic solvent solution for dissolving and reflowing an organic film. The substrate processing system comprises: the chamber having at least one gas inlet and at least one gas outlets; a gas introducing means which introduces the exposure process gas into the chamber via the gas inlet; and a gas distributing means. The gas distributing means separates an inner space of the chamber into a first space into which the exposure process gas is introduced via the gas inlet and a second space in which the substrate is disposed. The gas distributing means has a plurality of openings via which the first space and the second space communicate with each other and introduces the exposure process gas introduced into the first space into the second space via the openings.

TL;DR: A methodology and efficient algorithms for the design of high-performance system-on-chip communication architectures that automatically and optimally maps the various communications between system components onto a target communication architecture template that can consist of an arbitrary interconnection of shared or dedicated channels.
Abstract: In this paper, we present a methodology and efficient algorithms for the design of high-performance system-on-chip communication architectures. Our methodology automatically and optimally maps the various communications between system components onto a target communication architecture template that can consist of an arbitrary interconnection of shared or dedicated channels. In addition, our techniques simultaneously configure the communication protocols of each channel in the architecture in order to optimize system performance. We motivate the need for systematic exploration of the communication architecture design space, and highlight the issues involved through illustrative examples. We present a methodology and algorithms that address these issues, including the size and complexity of the design space. We present experimental results on example systems, including a cell forwarding unit of an ATM switch, that demonstrate the benefits of using the proposed techniques. Experimental results indicate that our techniques are successful in achieving significant improvements in system performance over conventional communication architectures (observed speedups over typical architectures such as single shared buses averaged 53%). Moreover, we demonstrate that our design space exploration methodology and optimization algorithms are efficient (low CPU times), underlining their usefulness as part of any system design flow.

TL;DR: The information terminal body may be designed to foldable pivot a pair of flat cases each having a display unit through a hinge which is equipped with a photographing optical system for the camera function unit of which optical axis of lens is perpendicular to an axial center of the hinge.
Abstract: The information terminal body may be designed to foldably pivot a pair of flat cases each having a display unit through a hinge which is equipped with a photographing optical system for the camera function unit of which optical axis of lens is perpendicular to an axial center of the hinge. The display units display information from communication channels and images taken in by the camera. The cases may have the display units such that the display units face outside in a folded state. At least one of the two display units may be a finder for photographers, while the other may be a finder for the subject persons. The terminal is equipped with a shutter button and a terminal operation button. The terminal operation button works also as a shutter button. The information terminal is also equipped with a viewfinder for the camera lens system.

TL;DR: In this article, a radio communication system comprises a base station for periodically transmitting a power saving signal and an information signal, a repeater station for relaying the signals, and a plurality of terminal stations for communicating with the base station through the repeater.
Abstract: A radio communication system comprises a base station for periodically transmitting a power saving signal and an information signal, a repeater station for relaying the signals, and a plurality of terminal stations for communicating with the base station through the repeater station. The repeater station includes power saving circuitry which responds to the power saving signal by cutting off power supplies to its major power consumptive components during a preset interval which alternates with an active interval during which power is supplied to the components. Each terminal station includes power saving circuitry responsive to the power saving signal relayed by the repeater station to cut off power suplied to its major power consumptive components during the preset interval and power saving disabling circuitry for transmitting a power saving disabling signal to the repeater station during the active interval in response to a request for call and disabling its power saving circuitry for the duration of the preset interval. The repeater station responds to the power saving disabling signal from a terminal station to disable its power saving circuitry for the duration of the preset interval to thereby permit the information signal to be relayed to the terminal station which has transmitted the power saving disabling signal. The terminal station then transmits a call request signal to the repeater station to permit it to be handled during the interval in which power saving is disabled.

TL;DR: A silicon oxide film is deposited on a substrate by chemical vapor deposition (CVD) using an organosilicon compound such as tetraethylorthosilicate (TEOS) and ozone as the principal reactants as discussed by the authors.
Abstract: A silicon oxide film is deposited on a substrate by chemical vapor deposition (CVD) using an organosilicon compound such as tetraethylorthosilicate (TEOS) and ozone as the principal reactants. The organosilicon compound gas and an ozone-oxygen gas which is relatively low in ozone concentration such as 0.1-1% are mixed in a gas mixer outside the CVD reaction chamber, and the resultant gas mixture is fed into the reaction chamber. Separately, another ozone-oxygen gas which is relatively high in ozone concentration such as 1-10% is introduced directly into the reaction chamber so as to come into contact with and mix with the aforementioned gas mixture in the vicinity of the substrate surface. The obtained silicon oxide film is good in film properties and step coverage, and the CVD operation does not suffer from deposition of reaction products in the gas feeding pipes and gas injecting nozzles.
