Liquid for prevention of substrate drying is supplied into a processing chamber so that a pool of the liquid is created as an anti-drying atmosphere in advance inside a processing chamber, and substrates, as they are dipped in the pool, are kept on stand-by in a substrate board. In this manner, air drying of the substrates which are kept on stand-by is prevented. When the number of the substrates in the substrate board reaches a certain number, the anti-drying atmosphere is removed from the processing chamber, which is followed by introduction of an SCF into the processing chamber and supercritical drying (high pressure drying) of all of the plurality of substrates inside the processing chamber, namely, batch supercritical drying.

A timer control circuit includes timers that perform count operations. A signal selection circuit selectively passes underflow signals supplied from the timers, based on control signals. A flip-flop is supplied with an output of the signal selection circuit section as a toggle signal.
摘要:
A communication system for e.g. an automobile including a system control unit for activating a selected audio/video device (such as an AM/FM tuner or a navigation system) in response to a request signal transmitted on a bus from a command input terminal. The system control unit generates command signals necessary to activate the selected audio/video device in response to the request signal, including command signals to de-activate any currently-operating devices. Conversely, adjustment commands (such as volume change or channel change commands) are transmitted directly (that is, unchanged by the system control unit) from the command input terminal to the selected audio/video device on the first bus line. In addition, the audio/video devices transmit reset signals whenever power is shut-off and then restored. Each reset signal includes a transmission source address corresponding to the audio/video device which transmitted the signal. The system control unit compares these transmission source addresses with a stored address corresponding to the selected audio/video device, and transmits a command signal to restart the selected audio/video device. Further, when the system control unit is turned off and then restored, the system control unit transmits a reset command to all of the audio/video devices connected to the bus.

Tuner for receiving a plurality of receiving frequencies and audio system having a plurality of audio components, characterized by the provision of a device for generating a designation command for selectively designating a program source such as a broadcast station at the receiving frequency of the tuner or an audio component, and an equalizer for adjusting the audio signal from the selected program source to have a frequency characteristic according to the program source designated by the designation command. By this provision, the need of operating tone controls at each time of the change of program source is obviated, so that the readiness of operation is improved.

An image forming apparatus having a main body with an opening portion provided in one face of the main body, and a thermal transfer printer. The thermal transfer printer records desired information additively on paper on which a toner image has been fixed. The printer uses a thermal head to press an ink-ribbon on the paper. The thermal transfer printer includes a casing in which a cassette for housing the ink-ribbon is detachably mounted, a thermal head support for supporting the thermal head, and an interlocking mechanism. The interlocking mechanism retracts the thermal head with the thermal head support in response to retraction of the casing. Thus, it is possible to detach the cassette from the main body through the opening portion. This facilitates replacement of cassettes and clearing of paper jams.
摘要:
Frequency characteristic setting circuitry for an amplifier generates frequency band data groups using a plurality of characteristic pattern data groups stored in a memory. Each of the frequency band data groups is made by making each item of data of a characteristic pattern data group retrieved from among a plurality of characteristic pattern data groups stored in the memory correspond to each frequency in a designated frequency band. The data groups generated for a plurality of frequency bands are combined together and the equalizing characteristic of the amplifier is controlled according to a characteristic pattern data group obtained by the combination.

The electronic device includes a control unit 10 configured to set in stages a plurality of thresholds which relate to the data based on press and cause a predetermined processing to be executed. The control unit 10 sets the thresholds such that, as the data based on press increases, the difference between thresholds gradually decreases.
