  • Hammer keyboard system and chassis
    Patent number: 7576273
    Abstract: A hammer with simplified structure and reduced costs that maintains its capability as a mass body to impart a touch weight. The hammer is configured such that it is possible to fix the two mass plates to the metal base plate by means of a single rivet. Therefore, the number of places in which the rivet holes are drilled and disposed in both mass plates and the metal base plate are kept to a minimum, and it is possible to limit the lightening of the weight of both mass plates and the metal base plate by that amount. As a result, since it is possible to configure the base plates and the metal base plate with smaller dimensions while maintaining the required weight, the capability as a mass body to impart a touch weight can be maintained while preventing the enlarging of the hammer overall.

  • ELECTRIC CONNECTING APPARATUS
    Publication number: 20090160469
    Abstract: In an electrical connecting apparatus, a thermal deformation restriction member, a reinforcing plate, and an auxiliary member are made of materials having smaller thermal expansion coefficients in this order, and a wiring board supporting a probe assembly is coupled with the reinforcing plate. The auxiliary member has a void inside the coupling region with the reinforcing plate. The void receives the deformed part when the center portion of the wiring board is deformed toward the reinforcing plate. Thus, the thermal deformation restriction member, the reinforcing plate, and the auxiliary member function as a three-layer bimetal having a sandwich structure, and the thermal deformation of the wiring board is restricted effectively.

  • AC power supplying system, power supply apparatus, and vehicle having the same
    Patent number: 7550861
    Abstract: Upon power failure of a commercial power source, an automatic switching device switches to power supply from a hybrid vehicle. An ECU of the vehicle, when receiving a request for generation of a commercial AC voltage, sets an upper-limit power generation amount based on a remaining amount of fuel. The ECU transmits the upper-limit power generation amount via an antenna to an on-premises ECU, while controlling a power generation amount based on the upper-limit power generation amount. The on-premises, when receiving the upper-limit power generation amount, controls the load state such that commercial AC power is supplied firstly to a first load of priority level 1, according to proprieties registered in advance, and such that the amount of the power supplied to the electric loads does not exceed the upper-limit power generation amount.

  • Hybrid vehicle
    Patent number: 7398844
    Abstract: A battery and a capacitor having a large capacity correspond to a power storage device for storing power used by a motor generator MG2. A controller detects state of charge of the battery and of the capacitor. When the driver issues an instruction requesting acceleration, the controller monitors the state of charge of the power storage device, and the controller instructs an inverter to increase contribution of the motor generator MG1 to an acceleration operation when the state of charge is insufficient to be larger than the contribution of the motor generator MG1 to the acceleration operation when the state of charge is sufficient. Thus a hybrid vehicle can be provided that allows a driver to feel smooth acceleration even if the power storage device is insufficiently charged.
