Abstract: A cutting insert of the present disclosure includes a top surface, a bottom surface, a side surface, and a corner cutting edge, a first cutting edge, a second cutting edge and a third cutting edge formed at a ridge line formed by the side surface and the top surface. The corner cutting edge has a first end and a second end. The first cutting edge extends from the first end in a first direction. The second cutting edge extends from the second end in a second direction. The third cutting edge extends from the second cutting edge in a third direction. The top surface has a first rake face adjacent to the first cutting edge, a second rake face adjacent to the second cutting edge, and a third rake face adjacent to the third cutting edge.

Abstract: An electric tool includes an output shaft and a controller. The output shaft is configured to hold a tip tool and be rotated by motive power provided from an electric motor with the output shaft holding the tip tool. The controller is configured to control rotation of the output shaft in accordance with pressing force in a direction from a tip end of the tip tool toward the output shaft. The electric tool has, as an operation range, a restriction range in which rotation of the output shaft is restricted in a state where the pressing force is less than or equal to a prescribed value.

Abstract: An electric tool system includes a motor, a control unit, and an output shaft. The motor includes a stator and a rotor. The control unit performs vector control on the motor. The control unit includes a first acquisition unit, a second acquisition unit, and a command value generation unit. The command value generation unit calculates, based on a torque current acquisition value (current measured value) as a value related to a torque current as acquired by the first acquisition unit and an acceleration acquisition value as a value related to acceleration of the rotor as acquired by the second acquisition unit, at least one of a command value of the torque current to be supplied to the motor or a command value of an excitation current to be supplied to the motor.

Abstract: An electric tool includes a pressure-sensitive sensor, a support, an output shaft, and a controller. The pressure-sensitive sensor is configured to sense pressing force which is externally provided. The support supports the pressure-sensitive sensor. The output shaft is configured to hold a tip tool and be rotated relative to the support by motive power provided from an electric motor with the output shaft holding the tip tool. The controller is configured to control rotation of the output shaft in accordance with an output according to the pressing force, the output being output from the pressure-sensitive sensor.

Abstract: Provided is a solar cell module having improved weatherability. A frame body has a groove. A module main body is inserted into the groove. An adhesive material is disposed in the groove. The adhesive material is provided at least on a part of a frame body portion excluding frame body corner portions. Through holes communicating with the groove are provided at the corner portions of the frame body.

Abstract: In a power converter, a first DC-DC converter converts a DC voltage output from a DC power supply into a DC voltage of a different level. A DC-AC converter converts a DC power output from the first DC-DC converter into an AC power and supplies the AC power to an AC load. A variable load unit connected to a current path that branches from a node between the first DC-DC converter and the DC-AC converter. A controller adjusts the variable load unit so that a total of a power consumption in the AC load and a power consumption in the variable load unit is equal to or larger than a predetermined power value.

Abstract: A solar cell module includes a solar cell panel including a plurality of solar cells sealed between a front surface member and a back surface member with a sealing material, and a frame supporting a peripheral edge portion of the solar cell panel. The frame includes a main body portion, a fitting portion which is located above the main body portion and in which the peripheral edge portion of the solar cell panel is to be fitted. The frame further includes an inner flange portion provided at a part of the main body portion below the fitting portion and not below a bottom portion of the main body portion and extending in a direction inward from the peripheral edge portion of the solar cell panel.

Abstract: A hydraulic excavator is provided with a lower traveling unit, an upper structure, an engine, a hydraulic pump, an engine compartment, a pump compartment and a plurality of filter devices. The upper structure is rotatably disposed on the lower traveling unit. The pump compartment provided on the upper structure for housing the hydraulic pump. The pump compartment has a door that allows access to an interior of the pump compartment. The filter devices, which are disposed adjacent to each other, are disposed at positions that are mutually offset in a height direction of the hydraulic excavator.

Abstract: An engine hood for a construction machine is configured to be pivoted in a vehicle body back-and-forth direction about a hinge attached as a pivot center to a longitudinal side part of a counterweight. The engine hood includes an engine hood main body, a first operating force applying unit and a second operating force applying unit. The engine hood main body is attached to a vehicle body of the construction machine in a pivotably openable/closable state. The first operating force applying unit is configured to apply force in a direction of opening the engine hood main body until the engine hood main body reaches a vicinity of a predetermined opening angle. The second operating force applying unit is configured to apply force in a direction of closing the engine hood main body when the engine hood main body is pivoted at the predetermined opening angle or greater.
