A semiconductor processing system including a semiconductor processing apparatus and a gas supply apparatus for supplying a process gas into the semiconductor processing apparatus includes a control section configured to control an operation of a pressure adjusting mechanism for adjusting the pressure inside a vaporizing chamber. The control section is preset to cause the pressure inside the vaporizing chamber to fall within a predetermined pressure range with reference to a pressure detection value obtained by a pressure detector. The predetermined pressure range is defined by an upper limit lower than a first limit value, at which vaporization of the liquid material starts being inhibited due to an increase in the pressure, and a lower limit higher than a second limit value, at which vaporization of the liquid material starts being unstable and the pressure inside the vaporizing chamber starts pulsating movement due to a decrease in the pressure.

A speaker cabinet design for providing adjustability of the number of speaker cabinets contained in a speaker array comprises female connectors (50) along the front and back edges on the top and right sides. A user of the cabinet can attach a mating second cabinet to any side of the first cabinet by inserting male connector (40) in the pass through assembly and securing to the female connector at all locations on that side. A user can connect a second speaker cabinet in a series or parallel electrical connection. This allows the user to build up to the desired number of speakers without purchasing a full speaker array. Furthermore, once the desired array is complete the user can remove only the number needed for transport. A variety of different speakers can be preloaded in the cabinet at the factory, thus giving the user flexibility in sound without having to remove and install different speakers.

An exemplary embodiment of the present invention docks a waterproof audio device into a recess in a top surface of a bodyboard (or other craft used in aquatic sports or related activities). Docking the device into the body of the craft serves to protect the device from impacts and mechanical stresses. The exemplary device comprises flat panel audio transducers, for example distributed mode loudspeakers and/or piezo transducers, or other flat panel audio transducer technologies, whether now known or in the future developed. The exemplary device is adapted for generating audio frequencies to produce high fidelity audio at sound pressure levels sufficient for the high noise environment that exists in aquatic sports. In the exemplary embodiment, the audio transducer(s) are acoustically coupled into the surface of the participant's aquatic sport craft and into the body of the craft. As a result of the acoustical coupling, the surface of the board, and the body of the board, act a distributed mode loudspeaker. In the exemplary embodiment, music playback is temporarily “paused” by two-way radio voice/data communication or by submersion of the device as detected by a submersion sensor. When incoming communication stops, or the device is no longer submerged, the music continues from the point it left off. This allows the participant to hear priority messages over the music program. It also allows the participant to resume music playback after surfacing. Further, the participant's ears are not obstructed so that verbal two-way voice/data communication with other participants nearby is no longer inhibited. The exemplary device has no visual display. Rather, the user interface is simplified, announcing verbal cues when switches are depressed. For example, when the participant depresses a volume key, the exemplary device announces “Volume Up.”
