  • Publication number: 20130230196
    Abstract: The present invention addresses the problem of increasing the lifetimes of an oscillatory wave motor and a sound generation device using the oscillatory wave motor as a drive source, and proposed the structure and mechanism for integrally increasing the lifetimes of the oscillatory wave motor and the sound generation device using the oscillatory wave motor as the drive source. To maintain the drive performance of a drive unit, the drive unit is provided with a core sheathing structure, with the result that the drive unit is prevented from breaking and being damaged, and even if the entire drive unit is worn down, an intrinsic drive unit member serving as a core portion keeps the same drive area, so an initial drive feature is maintained. The descending order of a wear resistance of the members is the drive unit core material, a moving unit, and a drive unit sheathing material.

  • Publication number: 20040062404
    Abstract: Defects in principle of low-frequency sound reproduction that conventional technologies essentially have are overcome by using a novel method for performing direct modulation when an air-current occurs. There is provided a speaker system, including an air-current generating unit for generating an air-current, and an air-current modulating unit for frequency-modulating the air-current generated by the air-current generating unit with a sound signal to which the driving of the air-current generating unit is input to generate sound waves in accordance with the sound signal.

  • Patent number: 6504089
    Abstract: A music search system easily operable by a user to search for a musical piece with accuracy, a method for operating the system, and a recording medium for use with the system. A plurality of music search factors can be successively input to the system, and one or more candidate pieces are presented based on effective inputs in the input music search factors. A user can efficiently supply the system with various sorts of music search information, and can obtain an optimal search result by using a search method particularly suitable for search by each sort of information. Input score information is reproduced according to the input operation, so that the user can immediately confirm most ambiguous score information when using the score information as search information, thereby reducing the probability of the system making an unnecessary search.

  • Patent number: 5988314
    Abstract: A sound output system has a pair of right and left speakers and a pair of audio mirrors for respectively controlling directivities of sounds which are output from the pair of speakers. The shapes or arrangement of the pair of audio mirrors are adjusted such that a difference between arrival times of the sounds which are respectively output from the pair of speakers can be compensated by a sound pressure difference due to the Haas effect in a predetermined area. Alternative means are phase difference, dipole, and asymmetrical horn loading.

  • Patent number: 4252883
    Abstract: An electrophotographic photosensitive member is prepared by dispersing photoconductive particle in a binder resin in a solvent and forming a photoconductive film by removing the solvent. Transition temperature of the binder resin and the preparation temperature are to be selected in such a way that the balance between these temperatures is within a certain range.

  • Patent number: 4168119
    Abstract: Electrophotographic copying apparatus of this invention includes an electrophotographic photosensitive member, elements for forming an electrostatic latent image on the photosensitive member, and for liquid developing the latent image, and elements for removing an excess liquid developer after the development and for applying thereafter substantially uniformly an electric field on the surface of the photosensitive member with the aid, for example, of a corona discharger or an electrode. The developed image is then transferred onto a transfer material and the photosensitive member is cleaned after the transfer, wherein each of these last two functions may be accomplished by conventional elements.

  • Patent number: 4004851
    Abstract: The outer surface of a transparent optical mass is directly coated with an internal reflection suppressing coating having an index of refraction smaller than that of the optical mass for suppressing internal reflections of light passing through the mass at angles of incidence to the surface greater than the critical angle. The coating includes a dispersing medium and a material in the form of light absorbing particles having dimensions smaller than one-fifth of the wavelength of visible light dispersed in the medium. The particles have a sufficient density near the surface to absorb a major portion of visible light at all wavelengths incident upon the surface through the mass at angles of incidence greater than the critical angle.

  • Patent number: 3948657
    Abstract: An electrophotographic photosensitive member is produced by a method in which a photoconductive layer is provided on a base, a polymeric solventless-type liquid resin adhesive is placed between said photoconductive layer and an overlying insulating layer and, by applying pressure on said insulating layer to spread said resin, said insulating layer is secured closely to the photoconductive layer through said adhesive layer. Fine grains of photoconductive material may be dispersed in said adhesive to provide a second photoconductive layer.This invention relates to a method for producing an electrophotographic photosensitive member and further to a method for obtaining a novel photosensitive member by employing said method.
