Abstract: A headphone includes: a housing, a hanger, and a bracket accommodated in the housing. The hanger includes: a connecting portion formed in a ring-shape; and a pair of engagement portions opposite to each other in a radial direction of the connecting portion and supports the housing unit to allow the housing unit to rotate. The bracket includes: a flexible curved base; and a pair of protrusions protruding at both ends of the base portion in directions away from each other on an axis penetrating the both ends. The housing includes a pair of through holes at positions corresponding to the pair of engagement portions. The pair of protrusions is rotatably engaged with the pair of engagement portions through the pair of through holes.

Abstract: In a headphone set, a speaker is enclosed in a housing. A cord is connected to the speaker at one end and running to the outside of the housing at another end through a pulling-out portion of the housing. The cord is inserted into a bushing at the pulling-out portion. An outer-shape expansion portion is fixed to the cord and located between the speaker and the bushing. The outer-shape expansion portion expands the outer shape of the cord. A concavity is provided to the bushing at one end of the bushing closer to the speaker. At least a portion of the outer-shape expansion portion is put in the concavity.

Abstract: An indicator device includes a light emitting element for emitting light, and a light conducting plate having a light incidence surface for conducting light from the light emitting element inside thereof and a light output surface, for a lighted indication by the light output surface. The light conducting plate has a triangular recess recessed to form with prescribed recess depths in one planer surface thereof, for light from the light emitting element to be reflected in part. The triangular recess has a recess extremity constituting a single vertex disposed in position on an optical axis of the light emitting element and nearer to the light incidence surface than other end parts thereof. The recess depths becomes shallower as the V-form recess extends from the recess extremity, allowing for an evenness of luminance of light over the light output surface formed on the light conducting plate.

Abstract: In a data transfer scheme using a caching technique and/or a compression technique which is capable of reducing the network load of a network connecting between data transfer devices, correspondences between data and their names are registered at the data transfer devices and the corresponding names are transferred, instead of transferring the data, for those data for which the correspondences are registered, so that it is possible to reduce the amount of transfer data among the data transfer devices.

Server side data transfer devices and client side data transfer devices can be provided in multiple-to-one, one-to-multiple, or multiple-to-multiple manners.

Abstract: In a data transfer device, presence/absence of a prescribed header in the received request message is analyzed, and information indicating the presence/absence of the prescribed header, or information indicating either presence or absence of the prescribed header when the prescribed header is either present or absent as a result of analysis is stored. Then, when a reply message corresponding to the request message is received, the presence/absence of the prescribed header is checked by referring to the stored information, and the reply message is transferred according to a result of checking.

Even when the name corresponding to the data is not registered so that it is impossible to transfer the corresponding name instead of transferring the data, it is possible to reduce the amount of transfer data among the data transfer devices by transferring the compressed data in which this data is expressed in a compressed form by utilizing the name corresponding to the registered reference data.

Abstract: A document searching apparatus includes a first storage unit that stores, in correspondence with one another, a normal form character, a variant form character, and rule identification information for identifying a conversion rule; a third storage unit that stores, in correspondence with one another, the normal form character, the rule identification information, document identification information, and location information of the character; an obtaining unit that obtains a input search word and a search condition that are input by a user; a first converting unit that converts the input search word to a normal-form search word; and a searching unit that performs a character search by comparing the normal-form search word and the search condition with the normal form character and the rule identification information that are brought into correspondence with each other by the third storage unit.

Abstract: In a stream processing system, a stream partitioned by a prescribed time interval is extracted as a partial stream, from one or more real streams formed by continuous time series data, according to playback position information or timestamps of the real streams, and a virtual stream is produced by concatenating one or more partial streams so as to enable a continuous playback. Then, a stream partitioned by another prescribed time interval is extracted as a partial virtual stream, from the virtual stream, according to playback position information or timestamps of the virtual stream, and a meta information related to a content of the partial virtual stream is stored in relation to the partial virtual stream.
