Provided is a relative pressure control system has a simple configuration, but enables accurate regulation of a division ratio of an operation gas, and concurrently makes it possible to securely drain the operation gas from an operation gas pipeline in case of emergency. The system includes a plurality of air operated valves of a normally open type that are connected to an operation gas pipeline supplied with an operation gas; pressure sensors that are series connected to the respective air operated valves and that detect output pressures of the respective air operated valves; a controller that controls operation pressures of the respective air operated valves in accordance with the pressures detected by the pressure sensors; and a hard interlock solenoid valve that correlates the plurality of air operated valves to one another so that at least one of the plurality of air operated valves is normally opened. In the configuration, an opening of a specified one of the plurality of air operated valves is regulated, the operation gas is output at a predetermined division ratio.

A system for successively extracting unprocessed substrates from a cassette, successively conveying the extracted substrates to a plurality of processing units, causing the processing units to process the substrates, and successively returning processed substrates to a cassette is disclosed. In the system, corresponding to a recipe that contains process conditions for each of at least one lot, a process start prediction time at which processes of each lot start and a process completion prediction time at which processes for each lot are completed are calculated for at least two processes. Corresponding to the process start prediction time and the process completion prediction time, at least one of optimum processing units that optimize processes for each lot is selected for each lot.

A wireless communication apparatus is capable of increasing data capacity that can be transmitted and reducing power consumption by reducing the amount of control signal to be transmitted, and capable of increasing system capacity by reducing interference with respect to other wireless communication apparatuses.In this apparatus, control information extraction section (105) extracts information indicating the number of CQI's contained in control information.Reception quality measuring sections (113-1 to 113-n) measure reception quality of each sub-carrier within a communication band.CQI generating section (114) generates CQI's for some of the sub-carriers of superior reception quality within the communication band.Multiplexer (122) multiplexes CQI's, sub-carrier number information generating the CQI's, and ACK signals or NACK signals.The SC selecting section (127) then selects the number of sub-carriers from a base station apparatus of superior reception quality allocated using the CQI quantity designation information.

A digital transmission circuit and method providing selectable power consumption via multiple weighted driver slices improves the flexibility of an interface while reducing transmitter power consumption, area and complexity when possible. A cascaded series of driver stages is provided by a set of parallel slices and a control logic that activates one or more of the slices, which combine to produce a cascaded active driver circuit. The power consumption / drive level selectability of the slice combination provides a driver that can be fine-tuned to particular applications to provide the required performance at a minimum power consumption level.

A music apparatus generates a plurality of music tones arranged in a set of performance parts of a music piece from a plurality of channels based on sequence data. A tone generator has a plurality of tone generating elements in correspondence to the plurality of the channels for generating therethrough the music tones in parallel manner. An assigning section assigns the plurality of the channels to the set of the performance parts such that each performance part may involve one or more of the channels. A sequencer processes the sequence data to sequentially provide parameters for use in the tone generating elements, the sequencer being operative when the assigning section assigns two or more channels to one performance part for providing first parameters set individually to each of said two or more channels and a second parameter set commonly to said two or more channels assigned to said one performance part. A register is divided into a first area for storing the first parameters provided from the sequencer and a second area for storing the second parameter provided from the sequencer. Each tone generating element uses both of the stored first parameter and second parameter set to the corresponding channel and characterized by both of the first and second parameters.
