  • Publication number: 20120321114
    Abstract: A hearing aid (100) comprises a body case (2) that is worn behind an ear (1), a sound conductor (3) that is linked at one end to the body case (2) and is linked at the other end to an earpiece (6), and an engaging component (8) for holding the earpiece linked to the other end of the sound conductor in the external auditory canal (7) of the ear (1). The engaging component (8) is made up of a first arc part (8a) disposed on the earpiece (6) side, a second arc part (8b) that is larger than the first arc part (8a) and is disposed opposite the first arc part (8a), a first linking part (8c) that links one end of the first arc part (8a) and one end of the second arc part (8b), and a second linking part (8d) that links the other end of the first arc part (8a) and the other end of the second arc part (8b). The second linking part (8d) has a shape such that its center part protrudes toward the first linking part (8c). This constitution allows the hearing aid (100) to be put on more easily.

  • Patent number: 8324063
    Abstract: An annular step portion provided to a periphery of a wafer housing portion is provided to an area with which an area of 1 to 6 mm from a boundary line with a chamfered surface of a wafer rear surface toward a wafer center comes in contact. As a result, it is possible to produce an epitaxial wafer having no scratch in a boundary area between the rear surface and the chamfered surface, and to eliminate particles generated due to a scratch in a device process.

  • Publication number: 20090314210
    Abstract: A susceptor for use in an epitaxial growth apparatus and method where a plurality of circular through-holes are formed in the bottom wall of a pocket in an outer peripheral region a distance of up to about ½ the radius toward the center of the circular bottom wall. The total opening surface area of these through-holes is 0.05 to 55% of the surface area of the bottom wall. The opening surface area of each of the through-holes provided at this outer peripheral region is 0.2 to 3.2 mm2 and the density of the through-holes is 0.25 to 25 per cm2. After a semiconductor wafer is mounted in the pocket, epitaxial growth is carried out while source gas and carrier gas (i.e., reactive gas) is made to flow on the upper surface side of the susceptor and carrier gas is made to flow on the lower surface side.
