  • Patent number: 10477295
    Abstract: The present invention relates to a canal type earphone configured such that an outlet for a sound wave to be reproduced is inserted into an inlet of a user's ear canal. The earphone includes an electrodynamic speaker unit configured to electroacoustically convert an audio signal into a high-frequency sound wave containing a band component having a higher frequency than that of an audible band of a human being, thereby emitting the high-frequency sound wave; an electromagnetic speaker unit configured to electroacoustically convert the audio signal into a low-frequency sound wave containing more band components having a lower frequency than that of the high-frequency sound wave, thereby emitting the low-frequency sound wave; and a housing to the inside of which the electrodynamic speaker unit and the electromagnetic speaker unit are attached.

  • Patent number: 7186060
    Abstract: In lining work in which a lining pipe R formed by spirally winding a strip-like member 500 consisting of an elongated sheet-form body is left in place inside a tubular culvert P, and a new lining pipe is additionally formed in front of this lining pipe that has been left in place, a lining apparatus S which has a flexible forming frame 1 consisting of link bodies is used. The strip-like member 500 is wound around the forming frame 1 by means of a joining mechanism part 7 attached to the forming frame 1, and a lining pipe R is formed while being forcibly folded inward utilizing the flexibility of the forming frame 1; at the same time, a back-filling material is injected into the inward-folded part. The inward-folded part later returns to its original state. Alternatively, the diameter of a small-diameter lining pipe R formed by winding around the forming frame 201 or 401 is expanded, and lining is performed with the back-filling material injected during this diameter expansion process.
