Abstract: [Problem] To provide a technology whereby power consumption can be reduced by reducing wasteful output of audio signals. [Solution] By comparison of an output volume level Vout of an output audio signal from a wireless speaker 1 with an input volume level Vin of an input audio signal to an audio controller 2, a volume level ratio Vin/Vout between the signals is monitored (S111). Moreover, when the volume level ratio Vin/Vout has dropped by a predetermined amount or more within a predetermined time period (S113, S120), a listener carrying the audio controller 2 is determined as having left a room in which the wireless speaker 1 is installed, whereby the volume value of the wireless speaker 1 is set to zero, and output of the audio signal from the wireless speaker 1 is stopped (S114, S121).

Abstract: Provided is an audio system in which an audio signal to be heard can be automatically set to an appropriate volume or sound quality. The audio system is provided with: a mobile terminal device provided with a microphone unit that collects surrounding sound waves, and a transmission unit that, on the basis of the sound waves collected by the microphone unit, sets the volume or sound quality of an audio signal to be amplified by an audio device, and transmits the set audio signal volume or sound quality information to the audio device; and an audio device provided with an amplification unit that amplifies the audio signal, a control unit that adjusts the audio signal volume or sound quality by means of the amplifier, and a receiving unit that receives the audio signal volume or sound quality setting information from the mobile terminal device.

Abstract: A contents data recording/reproducing method for use in a contents data recording/reproducing system comprising mutually connectable first and second recording/reproducing devices, the method comprising recording contents data input to either of the first and second recording/reproducing devices in the first and second recording/reproducing devices, respectively, wherein reproduction of only the contents data stored in either one of the first and recording/reproducing device is enabled when the first and second recording/reproducing devices are mutually connected, and reproduction of only the contents data stored in other of the first and recording/reproducing devices is enabled when the first and second recording/reproducing devices are not mutually connected.

Abstract: A method of producing a synthetic board involves the step of heat-pressing a mixture. The mixture includes lignocellulosic material containing lignocellulose and polybutylene succinate-based resin serving as an adhesive.

Abstract: A wooden member fabrication method which, by a simple process, can enable greater stability of shape subsequent to processing and uniformity of color tone. A wooden original piece with a long form has a hole thereinside which extends in the length direction. Corner portions are chamfered and radial direction thicknesses are substantially constrained to a certain range. An outer periphery of this wooden original piece is compression-deformed in directions toward an axial central portion and the outer periphery is thus made an arc surface. Because of the chamfering, radial direction thicknesses of the wooden original piece are constrained, and differences by location between compression ratios can be suppressed.

Abstract: There is provided a user interface processor (200) for generating a display screen on which a selectable item having a multi-level hierarchical structure is displayed to the user. The user interface processor is equipped with image information generators (202, 203, 204, 205) for generating two-dimensional image information including at least two lateral faces of a cube having lateral faces to each of which the selectable item having a different hierarchical level is assigned.

Abstract: A control key device includes a casing having a generally dome-shaped portion provided at an arbitrary part of the casing, the dome-shaped portion having a top surface and a hole provided at a central part of the dome-shaped portion, a substrate provided within the casing and having a plurality of electrical contacts, a resilient member provided on the substrate and having a plurality of bulges at positions corresponding to the electrical contacts of the substrate, each of the bulges having an electrically conductive portion which makes electrical contact with a corresponding one of the electrical contacts when the bulge is resiliently deformed, a contact pressing member provided on the resilient member and having a plurality of legs at positions corresponding to the bulges of the resilient member, and a key secured on the contact pressing member via the hole in the dome-shaped portion of the casing, the key having a home position and a tilted position.

Abstract: A control key device having a contact member which comprises at least a first and second contact portion such that when an operating force is applied to the first contact portion the second contact portion is caused to touch the first contact portion so that predetermined electrical contact is established. The causing of the second contact portion touching the first contact portion results from an operating force elastically transforming the shape of the contact member. A tilting mechanism is provided by a guiding member of predetermined shape having a through hole. The tilting mechanism functions to tilt the contact member in response to an operating force applied to the contact member. The contact member has a key portion and a pad portion defining a home position and a tilted position.

Abstract: Test equipment for a Multi Channel Access (MCA) wireless apparatus includes a Read/Write memory section which operationally replaces an ID.ROM of the apparatus for the purpose of the testing. A personal computer writes area, channel, system, tone group and user code data into the memory section which is read by the operating section in order to configure its channel setting. A measuring device receives code data for a channel setting at which operation is to be checked, sends a corresponding channel designating signal to the wireless apparatus, receives a response signal from the wireless, and forms and sends to the personal computer a result signal indicative of whether the response signal is accepted or rejected. The personal computer operates to send the code data to the measuring device under program control in response to keyboard operation by the user.
