A fastening device configured for an easy removable attachment to fabric that is employable with one hand to form a compressive engagement with a mounting point on fabric that is easy to use and non-damaging to fabric. The device may include a tuner to receive a signal, corresponding to a number of television channels, and to extract a second signal corresponding to a selected channel. The image erasing device includes a device for feeding the recording medium stepwise, and a cleaner for erasing the image forming on the recording medium by independently scanning the cleaner perpendicularly to the direction of feeding of the recording medium while the recording medium stays stationary. The studs are arranged such that an air gap between the studs and the first plate prevents arcing during the welding step. The present invention achieves the object by providing a transparent card with a hologram, characterized by comprising a configuration with a transparent card substrate made of a resin transparent with respect to a visible light, and a hologram layer having a computer generated hologram part to function as a transmission type Fourier transform lens laminated. A magnetic saturation is restrained by a non-magnetic layer formed in the power inductor, so that a DC bias characteristic corresponding to several hundreds of mA1A which could not be realized by the conventional multi-layer chip power inductor can be obtained .
