  • Publication number: 20130278025
    Abstract: A motorcycle seat frame, wherein a bottom surface part extending in a vehicle longitudinal direction and side surface parts standing upward at least at positions on both sides in a vehicle width direction of the bottom surface part are made of a fiber reinforced resin, thereby making an efficient improvement in the bending stiffness in a vehicle vertical direction possible using the anisotropy of the fiber reinforced resin, and also making marked weight reduction as a whole possible. The motorcycle seat frame achieves an efficient increase in bending stiffness in a desired direction in terms of material without improvement in mechanical structure, and enables marked weight reduction while required bending stiffness is ensured.

  • Patent number: 8565451
    Abstract: Under the control of a controller, a DSP supplies audio signals received from a switch circuit to a main zone DAC, subjects the audio signals received from the aforementioned switch circuit (i.e., audio signals for main zone use) to down-mixing processing so that the number of channels matches the number of output terminals assigned to each zone, and respectively supplies the audio signals subjected to down-mixing processing to the respective switch circuits of each zone. Each of the aforementioned switch circuits supplies the audio signals received from the subzone DAC to the respective volume adjustor of each zone.

  • Patent number: 8562162
    Abstract: A manipulation device has a board and a manipulation panel to cover the board. The board has a printed circuit, a light emitting element mounted on the board for emitting light, a light guide having a incidence part to guide the light incident from the incidence part to a predetermined direction along a surface of the board, and a retention cover to retain the light guide. The retention cover is positioned such that the incidence part of the light guide faces the light emitting element. The retention cover covers a surface of the light guide opposite to the surface of the board. The manipulation panel has a light transmission part formed at a position corresponding to an emission part of the light guide to discharge the light emitted from the light guide to an outside through the light transmission part.

  • Publication number: 20130269644
    Abstract: In a start control system for a vehicle, a memory stores a first setting value used to control a clutch to attain a start standby state and a second setting value used to control the clutch to attain a start preparation position. A clutch controller controls the clutch to attain a start standby state based on the first setting value upon determining that the vehicle has proceeded to a start standby period and controls the clutch to attain a start preparation state, in which the distance between the clutch disks is smaller than that in the start standby state, based on the second setting value upon determining the vehicle has proceeded to a start preparation period. The clutch controller controls the clutch such that the distance between the clutch disks is smaller than that in the start preparation state and carries out control such that an engine speed approaches an engine target speed.

  • Patent number: 8559647
    Abstract: A sound emitting and collecting apparatus that can accomplish stable echo removal if the relative positions of a loudspeaker and a microphone change is provided. A control section 52 inputs information of an arm rotation angle from a sensor 54. The control section 52 reads the filter coefficient corresponding to the input rotation angle from memory 53 and sets the coefficient in an adaptive filter 412A. When the arm rotates, the installing position of a microphone is changed and an acoustic transmission system changes, but a preset (or in the installing environment, updated) filter coefficient is set, whereby stable echo removal can be accomplished.
