Abstract:
To provide a headband capable of correctly placing an electrode on a head of a user, a headband apparatus includes a plurality of headband portions integrally connected and configured to be positioned about a head of a user, wherein at least two headband portions are each configured to be positioned behind an ear.
Abstract:
A semiconductor device wherein the diffusion depth of impurities in a diffusion layer is made uniform and a desired threshold voltage is obtained by a single diffusion, thereby improving the yield, and a method for manufacturing such a semiconductor device are provided. The semiconductor device has a channel layer (16) formed on a substrate (12), a diffusion stopping layer (17) formed on the upper surface of the channel layer (16), a diffusion layer (18) formed on the upper surface of the diffusion stopping layer, and a doped region (25) which is formed at least in a portion of the diffusion layer (18) so as to be in contact with the diffusion stopping layer (17) and into which impurities are diffused. The diffusion stopping layer (17) has an impurity diffusion rate lower than that of the diffusion layer (18), and thus stops the diffusion of impurities from the diffusion layer (18).
Abstract:
IT IS INTENDED TO PROVIDE A MULTI-LAYERED STRUCTURE FOR FABRICATING AN OHMIC ELECTRODE (7) FOR III-V COMPOUND SEMICONDUCTORS SUCH AS GAAS SEMICONDUCTORS WHICH HAS PRACTICALLY SATISFACTORY CHARACTERISTICS AND AN OHMIC ELECTRODE (7) OBTAINED BY USING IT. ON A III-V COMPOUND SEMICONDUCTOR SUBSTRATE SUCH AS AN N+-TYPE GAAS SUBSTRATE, A NON-SINGLE CRYSTAL SEMICONDUCTOR LAYER (3) SUCH AS A NON-SINGLE CRYSTAL INO. 7GAO. 3AS LAYER, A METAL FILM (4)SUCH AS A NI FILM, A METAL NITRIDE FILM (5)SUCH AS A WN FILM (4) AND A REFRACTORY METAL FILM SUCH AS A W FILM ARE SEQUENTIALLY STACKED BY SPUTTERING, ETC. AND SUBSEQUENTLY PATTERNED BY LIFT-OFF, ETC. TO MAKE A MULTI-LAYERED STRUCTURE FOR FABRICATING OHMIC ELECTRODES. THE STRUCTURE IS ANNEALED AT 500 TO 600°C, E.G. 550°C FOR ONE SECOND BY, E.G. RTA METHOD TO FABRICATE AN OHMIC ELECTRODE(7).
Abstract:
The present invention is directed to a headphone which comprises a pair of housing members into which speaker units and diaphragms are accommodated, protector members having sound radiating portions on which a plurality of sound radiating apertures are bored and respectively provided on the pair of housing members at their sound radiation sides from which a sound is radiated by a vibration of the diaphragms, and supporting members for supporting the housing members within the cavum concha of an auricle of a listener' ear so that the sound radiating portion is opposed to the entrance of an external auditory meatus in the auricle of the listener's ear, wherein the housing member has a concave portion that is engaged with one portion of the auricle of the listener's ear when the housing member is fitted into the auricle of the listener's ear.
Abstract:
To provide a biological signal measuring equipment that can perform the measurement in the same manner as the case of measuring a wave motion of a short period, even in the case of measuring the wave motion of a long period generated in a head portion. A biological signal measuring equipment used in the measurement of the biological signal in a head portion, has a jaw contact portion that comes into contact with a forehead; an occiput contact portion that comes into contact with the occiput; and a supporter that is interposed in a front and rear direction of the head portion and is supported by the head portion by using the jaw contact portion and the occiput contact portion as ends.
Abstract:
In one example embodiment, an information processing apparatus determines whether a target ID is a unique ID or a partial randomization ID that includes a first part being replaced by a different number and a second part being generated based on the unique ID. In response to the target ID being the partial randomization ID, the information processing apparatus generates an access key based on the second part of the partial randomization ID and a key. The information processing apparatus executes a mutual authentication process using the generated access key.
