  • Patent number: 7560629
    Abstract: A keyboard-type percussion instrument having sounding members arranged to correspond to respective ones of keys and capable of improving musical performance in soft tone. When a soft pedal is stepped on, a pedal connecting rod is moved upward to move an arm portion of a lifting arm upward, whereby the lifting arm is pivoted to cause capstan screws to be inserted into through holes of a key frame, thus moving a lifting bar upward so that an upper surface of the lifting bar projects from the key frame to push rear end portions of all the keys upward. As a result, standby positions of hammer felts are moved toward the sounding members, whereby the volume of a tone generated by a sounding member struck by a hammer felt corresponding to a depressed key is decreased.

  • Patent number: 7528310
    Abstract: A percussion instrument which is excellent in workability at the time of assembly and maintenance and capable of sustaining sounding members in vibration to generate high quality musical tones. The sounding members are arranged in the order of tone pitch, and a supporting cord is inserted through respective through holes formed in the sounding members. The supporting cord is formed at its surface with nonwoven fabric comprised of intertwined ultrafine fibers. The supporting cord inserted through the sounding members is supported at its portions located outside the through holes by fasteners provided on a lower surface of a resonance box.

  • Patent number: 7528311
    Abstract: A keyboard-type percussion instrument capable of outputting, with high quality, a musical tone to outside the instrument. In an upper part of the instrument, there is provided a tone generator unit including sounding members disposed to respectively correspond to keys of a keyboard and a resonance box in which musical tones generated by sounding members resonate. Action mechanisms each having a hammer felt for striking a corresponding sounding member are disposed below the tone generator unit. Reflection plates and a keybed formed with tone output ports are disposed below the action mechanisms. A musical tone generated by a sounding member struck by a corresponding hammer felt resonates in the resonance box, is output therefrom, passes through the tone output ports, is reflected by the reflection plates, and is output toward rearward of the instrument.

  • Patent number: 5339584
    Abstract: A synthetic resin window, e.g. for automotive vehicles, includes a window body member in the form of a sheet of transparent or semi-transparent synthetic resin, a hard coated layer covering and fusion-bonded to at the outer surface of the window body member, a frame member of a synthetic resin formed integrally with the body member to extend along a peripheral edge thereof, and connection between the frame member and the outer surface of the window body member. The connection may include a core element which is integrally connected to the window body member in a form-locking manner from outer and inner sides thereof, and at least partly embedded in said frame member. Alternatively, the connection may include bare surfaces of the synthetic resin forming the window body member, which are not covered by the hard coated layer and which are directly adhered to the frame member by an adhesive agent.

  • Patent number: 5178919
    Abstract: An elongate finisher member for automotive vehicles or the like, such as a lower window molding member, includes an elongate main body of predetermined length and cross-section. The main body has a mount portion with openings for passing fasteners to secure the finisher member to a vehicle body. The finisher member further includes a flap element which extends longitudinally along the main body. The flap element has a first end region integrally connected to the main body, and a second end region which is movable between an open position and a closed position. In the open position of the second end region, the flap element maintains the openings in the mount portion accessible from outside to facilitate insertion of fasteners into the openings. In the closed position of the second end region, the flap element covers the mount portion and maintains the openings and fasteners invisible from outside to provide a refined appearance.

  • Patent number: 5141278
    Abstract: A window molding member for automobiles includes at least one upper segment and at least one side segment to extend along upper and side edges of a window plate, respectively, which are integrally and continuously connected with each other. The molding member comprises a main body having a section with a longitudinally variable width, which is engageable with the outer surface of the window plate with a cushion element therebetween. The cushion element may have a longitudinally variable thickness to form a weir along the side segment for preventing rain water on the window plate from flowing across the side segment to preserve driver's sight through a side window.

  • Patent number: 5104173
    Abstract: A window molding member for automobiles includes upper and side segments to extend along upper and side edges of a window plate, respectively. Each segment comprises a leg section projecting from its main body to be inserted into a gap between the window plate and an automobile body panel. The leg section has a pair of webs defining a groove therebetween, for accommodating the edge of the window plate, and defines a channel along the side edge of the window plate. The molding is manufactured by a method which includes the steps of extruding continuous bodies corresponding to the main body and the leg section of the molding member, removing a predetermined amount of material from at least one of the extruded continuous bodies, and thereafter causing the extruded bodies to adhere with each other.
