  • Patent number: 9021858
    Abstract: An object is to prevent a bottle from being inclined when a weight is dropped, and to prevent cushion members from moving due to the impact applied when the bottle is inclined, thereby enabling efficient and correct measurement of the water hammer strength. An apparatus for testing the water hammer strength includes holding element that holds bottle filled with content and sealed with a cap at a position above the center of gravity thereof so as to suspend the bottle in the air, and the holding element is placed on cushion members placed on a fixing stage. A weight is then dropped onto the cap to measure the water hammer strength. The cushion members are compressed and deformed in advance using a compression element for forcing the holding element downward to solve the above-described problems.

  • Patent number: 8793045
    Abstract: A hybrid drive device includes a speed change mechanism, a motor drivingly coupled to an input shaft, and a clutch interposed between an engine and an input shaft. Upon engine start during engine traveling, the clutch is engaged, and rotation of the engine is increased. A control device of the hybrid drive device includes start upshift control means that, according to the engagement control of the clutch upon engine start, upshifts the speed change mechanism to output inertia torque. Thus, when the engine is started, output torque as the sum of driving torque of the motor and the inertia torque is output to the driving wheel, which reduces hesitation upon engine start.

  • Patent number: 8715135
    Abstract: A control device for a hybrid vehicle automatic transmission. A friction engagement element control unit includes a first play elimination control unit that sets a first pressure as the pressure for a first set time where the predetermined friction engagement element is engaged using a hydraulic pressure from the electric oil pump in a travel state in which only the rotary electric machine serves as a drive source. The first play elimination pressure is lower than a play elimination pressure for use in the case where the predetermined friction engagement element is engaged using a hydraulic pressure from the mechanical oil pump in a travel state in which the internal combustion engine serves as a drive source.

  • Patent number: 8629698
    Abstract: There is provided a mixing circuit in which a rise of the consumption current can be suppressed while decreasing a non-linear component. The mixing circuit includes: an input unit 803 including a grounded-gate MOS transistor M1 with a source into which an input signal is input, and a grounded-source MOS transistor M2 with a gate into which the input signal is input; a frequency converter 802 for converting frequencies of a first current signal output from the grounded-gate MOS transistor M1 and a second current signal output from the grounded-source MOS transistor M2, and for generating a third current signal and a fourth current signal; a load MOS transistor M7, with a gate and a drain connected, for receiving a third current signal; and a load MOS transistor M8, with a gate and a drain connected, for receiving a fourth current signal.
