    摘要: The sizes of the respective reflecting units vary in the image take-out section along the Z direction in association with the state of the total reflection angle in the light guide section. Thus, it becomes possible to keep the sufficient effective light beam width of the image light input thereto in all of the reflecting units. Therefore, the deterioration in the image light caused by the reflection in the reflecting units can be avoided, and as a result, the degradation of the resolution of the image due to the virtual image light thus emitted can be prevented.

    摘要: A virtual image display device has a light guide device in which the half mirror layer (the semi-transmissive reflecting film) of the light guide member is formed on the partial area of the first junction surface, and the second junction surface of the light transmitting member is bonded to the first junction surface in at least the exceptional area. Therefore, it is possible to increase the bonding strength of the first junction surface and the second junction surface, namely the strength of the light guide device composed of the light guide member and the light transmitting member combined with each other even in the case in which the attachment force of the half mirror layer (the semi-transmissive reflecting film) with respect to the first junction surface is not sufficiently strong.

    摘要: A sound device includes an input terminal for electronic signal input; a line out terminal adapted to output electronic signals input on the input terminal to an external area; a delay arrangement adapted to delay electronic signals input on the input terminal for a certain time; a main output arrangement adapted to output electronic signals delayed by the delay arrangement. The delay arrangement delays signals in order to accommodate a time difference between (1) electronic signals output from an external sound device connected with the line output terminal and (2) electronic signals output from the main output arrangement. The time difference between sound that is output from the sound device and the one that is output from an external sound device that is connected with line connection terminal can be eliminated. Thus, it can prevent sound quality decrease due to time difference from happening.

    摘要: A speaker system comprising a magnetic circuit, a cylindrical shaped voice coil unit generating oscillation in the magnetic circuit, an oscillating plate extending in a circular conical shape from a outer peripheral surface of the voice coil unit, a dust cap connecting to the oscillating plate covering an open face of the voice coil unit on a side surrounded by the oscillating plate, a plurality of linking members connecting to the voice coil unit, and a detection unit. The link members extend toward a center axis of the voice coil unit. The detecting unit further comprises a first component part fastened to the linking members and positioned at the center axis of the voice coil unit closer to the voice coil unit side than the dust cap, and a second component part positioned facing the first component part and is independent of the voice coil unit such that the second component part is held between the first component part and the dust cap. The detecting unit optically detects the oscillations of the voice coil unit by means of a light that courses between the previously mentioned first component part and the second component part.

    摘要: A thin-film magnetic head provided with a magnetic thin film having a magnetostrictive characteristic is disclosed in which a central part of magnetic core formed of the magnetic thin film has a positive magnetostriction constants, and side parts of the magnetic core on both sides of the central part have negative magnetostriction constants. Thus, when a stress due to the patterning of the magnetic core varies the magnetic characteristic of the magnetic core, the permeability of the magnetic core becomes high, and the magnetic stability thereof is improved. Accordingly, a signal reproduced by this magnetic head has a high output level, and is low in noise level.
