Abstract: One aspect of the present invention relates to a method for manufacturing a substrate with a conductive pattern, the method including: a base forming step of forming a plating base in a desired pattern on at least a portion of one surface of a stretchable substrate, wherein the stretchable substrate has a tensile modulus at 20° C. of 0.1 MPa or more and 500 MPa or less, an elongation at break of 100% or more and 1000% or less, and a storage modulus at 250° C. of 0.1 MPa or more; a bending step of bending the stretchable substrate; and a conductive pattern forming step of plating the plating base after performing the bending step to form a conductive pattern on the stretchable substrate.

Abstract: A method for manufacturing a stretchable circuit board includes preparing a laminate in which a metal layer and a first stretchable insulating layer are in contact with each other and a peel strength between the metal layer and the first stretchable insulating layer is 0.5 N/mm or more and 3.0 N/mm or less, a second stretchable insulating layer, and a fluid; forming a via leading from a first surface, in contact with the metal layer, of the first stretchable insulating layer to a second surface opposite to the first surface; filling the fluid in the via; laminating the second stretchable insulating layer on the second surface to seal the via; and patterning the metal layer.

Abstract: A circuit mounted article to be fixed to a fabric is provided and includes a circuit board having flexibility, an electronic component mounted on a fabric facing face side, which faces the fabric, of the circuit board, and further a reinforcing portion to be used for fixing of the circuit mounted article to the fabric on the fabric facing face side of the circuit board.

Abstract: An internal combustion engine includes an internal combustion engine body including an intake valve and an exhaust valve, and a controller configured or programmed to perform a control to set a rotational speed of the internal combustion engine body to a predetermined rotational speed based on an environmental temperature at a time of starting the internal combustion engine body, and perform a control to drive the internal combustion engine body at the set predetermined rotational speed during a time period until when fuel is supplied to a combustion chamber of the internal combustion engine body and first ignition is performed.

Abstract: A driving-side rotating body that rotates synchronously with a crankshaft of an internal combustion engine, a driven-side rotating body that is allowed to rotate relative to the driven-side rotating body and that rotates integrally with a camshaft that opens and closes an intake valve, and a phase adjustment mechanism for setting a relative rotation phase of the driving-side rotating body and the driven-side rotating body using a driving force of an electric motor are included. The phase adjustment mechanism is configured to be able to execute retarding control for setting the relative rotation phase to the retarding side until reaching a phase in which the internal combustion engine cannot be started and autonomous running is not possible even if fuel injection and ignition are performed in the internal combustion engine.
