  • Patent number: 11079850
    Abstract: In an input apparatus, under a state where contact of a manipulating body to a predetermined position on a manipulation surface is detected, a second low frictional force between the manipulation surface and the manipulating body is provided by vibrating the manipulation surface. The second low frictional force is smaller than a frictional force between the manipulation surface and the manipulating body when the manipulation surface is not vibrated. In response to determining the movement of the manipulating body from the predetermined position towards a target position on the manipulation surface, a first low frictional force between the manipulation surface and the manipulating body is provided by a predetermined time by vibrating the manipulation surface. The first low frictional force is smaller than the second low frictional force.

  • Patent number: 9140312
    Abstract: A hydraulic control device configured with a source pressure generation section, a hydraulic servo for a clutch provided between an engine and a motor, a control solenoid valve that outputs a regulated source pressure to the hydraulic servo, and a switching section that switches a hydraulic passage, which extends between the source pressure generation section and the hydraulic servo to supply the engagement pressure, between a first and second state in which the hydraulic passage has a high conduit resistance compared to the first state at least until the clutch is engaged. The switching section switches the hydraulic passage into the second state during a failure in which the control solenoid valve is de-energized and the source pressure is directly supplied to the hydraulic servo as the engagement pressure, and switches the hydraulic passage into the first state during normal times when the failure does not occur.

  • Patent number: 8643131
    Abstract: According to one embodiment, a solid-state imaging device includes a diffusion layer, first and second diffusion layers, and p-type amorphous silicon compound. The diffusion layer of a first conduction type is formed in a surface of a semiconductor substrate of the first conduction type. The diffusion layer functions as a charge accumulation part for accumulating electrons generated in the semiconductor substrate by light emitted from a back side of the semiconductor substrate to a surface side. The first and second diffusion layers of a second conduction type sandwich the charge accumulation part and are formed so as to reach the inside of the semiconductor substrate from the surface of the semiconductor substrate. The p-type amorphous silicon compound electrically isolates the charge accumulation part and is buried in the first and second trenches formed on the back side of the semiconductor substrate.
