  • Publication number: 20190088688
    Abstract: To make the dimension of an electrostatic protection circuit small with the same maintained high in sensitivity. The electrostatic protection circuit is of the configuration that a first diode and a second diode are connected in series, wherein a semiconductor layer owned by each diode is configured to be sandwiched between a gate electrode and a conductive light shielding film. The light shielding film is formed to overlap with the semiconductor layer and has a wider area than the semiconductor layer. This results in having a gate covering the semiconductor layer from an upper side and a back gate covering the semiconductor layer from a lower side, so that the sensitivity can be maintained high irrespective of decreasing the electrostatic protection circuit in dimension.

  • Patent number: 10175622
    Abstract: A fuser includes a pressure pad forming a nip with a fuser belt between the pad and a fuser rotator. A pressure face in contact with the belt has profiles in planes normal to the axis of the rotator. The profiles each include a reference section, the first to come into contact with the rotator with the belt in between when the pad forms the nip, and a boundary section at a threshold distance from the reference section in the width direction of the nip. When the pad is apart from the nip due to removal of a force applied by a pusher unit, the boundary section is, relative to the reference section, more largely displaced in the opposite direction to that of the rotator in one of the profiles located at a larger distance from a center portion of the pad in the axial direction of the rotator.

  • Patent number: 10086821
    Abstract: When there is a history that a required torque has reached a high torque range and the required torque falls within a low torque range, a start threshold is changed from a value larger than a maximum double-drive torque to a value smaller than a selection threshold for selecting a single-drive mode or a double-drive mode. When the required torque becomes larger than the start threshold, an engine is started.

  • Patent number: 10081085
    Abstract: A tool changer includes a holding member having a tool change arm, a rotating mechanism for rotating the holding member, a forward/backward moving mechanism for moving the holding member forward and backward, and a controller controlling the mechanisms. A zero return controller determines whether the tool change arm is holding tools. When it is not holding tools, the tool change arm is rotated to a predetermined non-interference angle, the tool change arm is translated to a forward/backward movement zero point, and the tool change arm is rotated to a rotation zero point. When it is holding tools, the tool change arm is translated to a forward end, the tool change arm is rotated to position it on an expected path, and the tool change arm is moved along the expected path, thereby moving the tool change arm to the rotation zero point and the forward/backward movement zero point.

  • Patent number: 10035502
    Abstract: When an output limitation value of a battery is equal to or less than a threshold, an electronic control unit determines that basic torque is able to be output from a second motor to a drive shaft. Then, the electronic control unit sets a predetermined value as a target motoring rotation speed for ending motoring of an engine by a first motor. When the output limitation value is greater than the threshold, the electronic control unit determines that the basic torque is unable to be output from the second motor to the drive shaft at the time of starting the engine, and sets a value smaller than the predetermined value as the target motoring rotation speed.
