A lock detecting device () which is capable of detecting a state of a thumbturn () and transmitting a detection result and is very versatile and device costs of which are small is provided. A sensor portion that detects whether the state of the thumbturn () is in a first state or in a second state orthogonal to the first state and a wireless communication portion that transmits a signal corresponding to a detection result of the sensor portion by wireless communication are included.

Installing method of detecting device that detects state of thumbtuirn, and detecting device installable thereby

A receiver apparatushas a digital circuit portionthat converts a compressed digital signal outputted from a digital demodulating portioninto digital video and audio signals, a video/audio output circuitthat converts the digital video and audio signals outputted from the digital circuit portioninto analog video and audio signals, and an intermediate-frequency processing circuit portionthat converts an intermediate-frequency signal into an audio intermediate-frequency signal. With this configuration, a video/audio processing IC for digital signal processing no longer needs to be mounted on the circuit board of a video display apparatus, and thus a receiver system can be realized with a video display apparatus having a simple configuration.

Receiver apparatus and receiver system

An oscillator including a circuit board having a dielectric layer therein; an oscillator circuit comprising its components and an inductor element, the components being mounted on a front surface of the circuit board and at least a part of the inductor element being internally disposed in the dielectric layer; and a back conductor provided on a back surface of the circuit board; wherein the back conductor has two or more slits or pinholes through which a laser beam is passed for partially cutting the dielectric layer together with the internally disposed inductor element at plural sites for adjustment of an oscillation characteristic.
