  • Patent number: 11387211
    Abstract: A bonding apparatus bonds a semiconductor die, which has a first mam surface provided with a bump electrode, to a substrate by means of thermo-compression, with a thermo-compression film being interposed therebetween. The bonding apparatus includes: an intermediate stage that has a die placing surface on which the semiconductor die is placed such that the die placing surface faces the first main surface; and a bonding tool which detachably holds a second main surface of the semiconductor die that is placed on the intermediate stage, the second main surface being on the reverse side of the first main surface. The intermediate stage has a push-up mechanism which applies, to the first main surface of the semiconductor die, a force for separating the semiconductor die therefrom in the normal direction of the die placing surface (in a Z-axis direction).

  • Patent number: 10563706
    Abstract: Provided is a hydraulic power transmission device enabling to minimize a pressure loss in an oil passage downstream from a piston chamber of a hydraulic clutch, and to properly prevent reduction in transmission torque capacity in the hydraulic clutch. Left and right pressure regulating valves (8L, 8R) regulating pressure of oil flowing out from piston chambers (59L, 59R) of left and right clutch devices (5L, 5R) are arranged adjacent to a downstream of the piston chamber (59). This can shorten an oil passage from the piston chamber (59) to the pressure regulating valve (8) and minimize pressure loss in the oil passage. Due to better flexibility of arrangement of the pressing load receiving member (82) receiving a pressing force (thrust) of the piston member (57), thrust efficiency of the hydraulic piston (57) improves to properly prevent reduction in transmission torque capacity in the hydraulic clutch (5).

  • Patent number: 9909629
    Abstract: A drive force transmission device provided in a vehicle includes a rotating shaft, a gear chamber, a first clutch chamber, a hydraulic oil supplier, an oil reservoir, and an oil temperature sensor. The rotating shaft extends in an axial direction and is rotatable around the axial direction to transmit a drive force to left and right drive wheels of the vehicle. The gear chamber houses a gear via which the drive force is to be transmitted to the rotating shaft. The drive force transmission device has a first side and a second side opposite to the first side with respect to the gear chamber in the axial direction. The first clutch chamber is disposed on the first side and houses a clutch that is to distribute the drive force transmitted from the rotating shaft to the left or right drive wheels.

  • Patent number: 9697471
    Abstract: A plant model management device according to one embodiment includes a generation unit and a combining unit. The generation unit receives a first set of prior probability distributions of a first set of automatic operation parameters. The first set of automatic operation parameters define a condition required for modeling a plant model that is a model based on data concerning a plant. The generation unit generates a first set of posterior probability distributions of the first set of automatic operation parameters and a first set of probabilistic plant models based on the first set of prior probability distributions. The first set of posterior probability distributions reflect compatibility with learning data that is past time-series data concerning a first explanatory variable and a first objective variable. The combining unit combines the first set of probabilistic plant models using the first set of posterior probability distributions to generate a first plant model.

  • Patent number: 9189198
    Abstract: There is provided a data similarity calculation method. The method includes: (a) acquiring a first waveform; (b) storing time series data; (c) converting the stored time series data into a waveform on two-dimensional coordinates, wherein the two-dimensional coordinates consists of a time axis and an a value axis representing values of the time series data, and the time axis is orthogonal to the value axis; (d) shifting the converted waveform in both directions of the time axis and the value axis so as to generate a second waveform; (e) calculating a similarity between the first waveform and the second waveform; and (f) extracting a shift amount in the direction of the time axis and a shift amount in the direction of the value axis when the similarity is the highest by repeatedly performing steps (d) and (e).

  • Patent number: 9150090
    Abstract: In a power transmission system, a ring gear of a first speed reducer and a ring gear of a second speed reducer are coupled to each other and have the same rotational axis. An engagement portion between the ring gear and a planetary gear is formed such that, when a first motor generates a rotational torque in the forward direction, a force acts on the ring gear in a direction approaching the second speed reducer in the rotational axis direction. An engagement portion between the ring gear and a planetary gear is formed such that, when a second motor generates a rotational torque in the forward direction, a force acts on the ring gear of the second speed reducer in a direction of approaching the first speed reducer in the rotational axis direction.
