  • Patent number: 8814627
    Abstract: A toy set that enables communication between a game device and a toy without changing a hardware configuration of the game device includes a program stored in a storage medium that when executed causes the game device to detect a sequence of single frequency sounds, output a voice corresponding to a combination of the detected sounds, generate a plurality of single frequency sound and generate a control signal by a combination of the sounds. The toy incorporates a sound generation means, a voice input means, a control means and a sensing means. The control means includes a generation means for generating a control signal as a sequence of plurality of single frequency sounds sent out from the sound generation means of the toy. When the control signal is inputted from the game device, the toy performs a predetermined action which corresponds to the control signal.

  • Patent number: 6463657
    Abstract: A method of manufacturing a valve element adapted to be mounted into a selenoid valve to open and close a valve seat of the valve. The method comprising a step of preparing a leaf spring including an outer peripheral ring section and a hub section, a step of forming an outer peripheral seal by vulcanizing and molding an elastic material along the outer peripheral ring section, a step of preparing a valve disk to be fitted to one surface of the hub section, and a step of providing a valve seal to be held in contact with the valve seat. The method further compring a step of preparing a movable core having a flange section arranged on an opposite surface of the hub section, a step of preparing a holder ring and bonding the holder ring to the valve disk wherein the movable core is secured to the leaf spring.

  • Publication number: 20010002041
    Abstract: A valve element comprises a leaf spring carrying a movable core fitted thereto and is adapted to be mounted into a solenoid valve in order to open and close the valve seat of the solenoid valve. The leaf spring includes an outer peripheral ring section, a hub section having a central hole and one or more than one connection holes and a plurality of radial arm sections for connecting said outer peripheral ring section and said hub section. An outer peripheral seal is made of an elastic material such as rubber and arranged along the outer peripheral ring section of the leaf spring. A valve disk to be fitted to one of the opposite surfaces of said hub section of said leaf spring is provided with a valve seal also made of an elastic material such as rubber that is to be held in contact with the valve seat. A movable core having a flange section is arranged on the other surface of said hub section with the flange section held in contact with the hub section.
