  • Patent number: 11958467
    Abstract: A hybrid driving apparatus is provided which enables a driver to sufficiently enjoy a driving feeling of a vehicle driven by an internal combustion engine. A hybrid driving apparatus includes an internal combustion engine that drive main driving wheels, a motive power transmission mechanism transmitting a driving force to the main driving wheels, a main driving electric motor driving the main driving wheels, an accumulator, sub-driving electric motors transmitting motive power to sub-driving wheels of the vehicle, and a control apparatus executing an electric motor traveling mode and an internal combustion engine traveling mode. The control apparatus causes the internal combustion engine to generate the driving force, the internal combustion engine is a flywheel-less engine, and the control apparatus causes the main driving electric motor to generate a torque for maintaining idling of the internal combustion engine in the internal combustion engine traveling mode.

  • Patent number: 11441101
    Abstract: A cleaning composition which can remove a layer of interest using a conventional apparatus, such as a coater, a baking furnace and a cleaning chamber, installed in semiconductor manufacturing equipment while preventing the damage or deformation of layers other than the layer of interest, such as a substrate and an interlayer insulation film; a cleaning method using the cleaning composition; and a method for producing a semiconductor employing the cleaning method. A layer of interest formed on a substrate is cleaned with a cleaning composition containing a component capable of decomposing the layer of interest and a film-forming polymer. An example of the layer of interest is a hard mask film. An example of the component is at least one of a basic compound and an acidic compound.

    Abstract: A washing method, a washing device, a storage medium, and a washing composition for enabling effective removal of a layer to be processed by decomposing or degenerating the layer to be processed at a higher temperature than conventionally. In a state where a substrate provided with a layer to be processed is heated, the substrate is supplied with vapor of a component that can decompose the layer to be processed, and thereafter the layer to be processed that has reacted with the component is removed from the substrate. As the component, a nitric acid or a sulfonic acid is preferable. As the sulfonic acid, a fluorinated alkyl sulfonic acid is preferable.
