Abstract: A robot system includes a robot, and an information processing portion. The information processing portion is configured to obtain a learned model by learning first force information about a force applied by a worker to a workpiece, first position information about a position of a first portion of the worker, and first workpiece information about a state of the workpiece, and control the robot on a basis of output data of the learned model.

Abstract: A turbocharger system of an embodiment includes: a wastegate valve; an electrically-operated actuator configured to adjust a valve lift of the wastegate valve; a temperature acquisition unit configured to acquire a target temperature which is a temperature of the turbocharger body or a temperature correlating with the temperature of the turbocharger body; and an actuator controller configured to control the electrically-operated actuator on the basis of the target temperature. The temperature acquisition unit acquires the target temperature, and the actuator controller controls the electrically-operated actuator on the basis of the target temperature.

Abstract: The power-assisted supercharger (10) includes: a turbocharger (12) in which a turbine (12a) is rotationally driven by exhaust gas (7) from an engine (40), a compressor (12b) rotationally driven by the turbine compresses intake air (5) and supplies the intake air to the engine; an electric motor (14) connected to a rotary shaft (12c) connecting the turbine and the compressor, the electric motor to add rotational force to the turbocharger; and a motor controller (20) to control a drive current (I) to the electric motor required for an assist operation for the turbocharger, by open loop, based on an accelerator opening degree (A) of the engine and a rotational speed (NE) of the engine. In this power-assisted supercharger, a turbo lag can be reduced by itself, power consumption can be small even in a range in which the rotational speed is high, malfunctions or unnecessary power consumption can be prevented, a control system can be simplified, and the installation space and the weight thereof can be small.

Abstract: A warming-up system performing a catalytic converter warming-up method has an electric motor (1m) enabling a turbocharger (1) to increase the amount of air supplied to an internal combustion engine (2) regardless of the amount of exhaust gas flowing through a turbine (1t) of the turbocharger (1), a variable nozzle (1n) regulating the flow of exhaust gas through the turbine (1t), and an ECU (5) for controlling the operation of the electric motor (1m) and the variable nozzle (1n) and the amount of fuel supplied to the internal combustion engine (2). After the internal combustion engine (2) is started, the ECU (5) warms up the catalytic converter (4) by driving the electrical motor (1m) to forcibly rotate the turbine (1t), opening the variable nozzle (1n), and increasing fuel supply to the internal combustion engine (2).

Abstract: A gasification apparatus is provided which enables gas hydrate pellets to be transported and gasified in the same vessel and enables a gas to be generated by pellet decomposition in a controlled amount. The apparatus is free from bridging. The apparatus includes a heat-in-saluted vessel main body and, disposed therein, a tubular structure which is open at the top and bottom. This tubular structure holds therein gas hydrate pellets obtained by compression-molding a gas hydrate produced by the hydration reaction of a raw-material gas with raw-material water. The tubular structure becomes wider in diameter from the upper opening toward the lower opening. A channel for passing a heat carrier therethrough has been disposed between the lower end of the tubular structure and the inner bottom surface of the vessel main body.

Abstract: A particulate filter regeneration system regenerates a particulate filter provided in an exhaust line of an engine equipped with a turbocharger by burning matter trapped on the particulate filter by raising the temperature of exhaust gas at times that the particulate filter requires regeneration. The system has an electric motor functioning as an intake quantity regeneration portion capable of increasing the flow rate of compressed air without depending on the flow rate of exhaust gas flowing across a turbine of the turbocharger, a bypass line connecting an engine intake line upstream of the engine to a section of the exhaust line upstream of the particulate filter, a flow rate regulation valve regulating the flow rate in the bypass line, and a control portion controlling the electric motor and the flow rate regulator.
