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 method of mounting a flat panel speaker is provided which is capable of reliably preventing entry of dust and of shortening assembling time. By bonding a gasket member to a diaphragm, by pasting a separator to a gasket member side opposite to the diaphragm and, by sandwiching the diaphragm and the gasket member from both sides, a gasket-attached diaphragm is fabricated. After peeling off a protecting sheet on a rear side of the gasket-attached diaphragm, the actuator module is bonded to the diaphragm. Then, after peeling the separator from the gasket-attached diaphragm, positioning is performed on the diaphragm and the gasket member is bonded to a putting-face of the front case. The entry of dust into a region corresponding to a liquid crystal display panel is blocked by a partitioning portion of the gasket member.

An overhead microphone assembly using multiple unidirectional microphone elements. The microphone assembly is installed overhead, generally above all the desired sound sources and below the undesired sound sources. The signals from these multiple microphone elements are fed into a microphone steering processor which can mix and gate the signals to ensure the best signal/noise ratio. The steering processor may also track the sound source dynamically when such tracking (source locating) is desired. The resulting audio signal from the steering processor may be further processed, such as echo canceling, noise reduction and automatic gain control.
