Abstract: A thermistor layer of the present invention is configured to be disposed in an electrical current path. The thermistor layer comprises a thermosensitive particle, a plurality of electro-conductive particles covering a surface of the thermosensitive particle, and a binder adhering the electro-conductive particles, the electro-conductive particles form an electro-conductive network, at least the surface of the thermosensitive particle is made of a thermoplastic resin, the thermoplastic resin softens at a temperature lower than a temperature at which the binder softens, and the thermistor layer is provided to become highly resistive due to softening and deformation of the thermoplastic resin.

Abstract: A cooling efficiency is increased. An inkjet head is provided with a head main body for jetting ink, a cooling pipe which has corrosion resistance to the ink, and through which the ink for cooling a drive circuit passes, and a cooling member which has higher thermal conductivity than that of the cooling pipe, in which at least a part of the cooling pipe is embedded, and which has recessed parts in at least a part of a portion surrounding the cooling pipe.

Abstract: In a cylinder head (1) having a built-in exhaust manifold (6) of an engine (10), outer coolant passages (23A and 23B) in which an engine coolant circulates are provided, and are disposed along the manifold positioned at a side of an outer surface (14C) of the cylinder head (1). Further, inner coolant passages (24A and 24B) having shapes which are branched from the outer coolant passages (23A and 23B) and then join are provided, and are disposed along the outer coolant passages (23A and 23B) and at an inner side of the cylinder head (1).

Abstract: A connection member for connecting an exhaust manifold and an exhaust pipe of an internal combustion engine, includes a flange portion, a boss portion and an attachment portion. The flange portion has a plate shape with an opening configured to be fixed to the exhaust pipe in a state where the opening communicates with the exhaust pipe. The boss portion is provided to bulge from the flange portion on an outside of the opening in a radial direction of the opening, is configured so that a sensor configured to detect components of the exhaust is attached to the boss portion, and is configured to be fixed to a portion of an outer circumferential surface of the exhaust pipe. The attachment portion protrudes from the flange portion and is configured so that a protection member which covers the exhaust pipe is attached to the attachment portion.

Abstract: An exhaust system structure of an internal combustion engine, includes an exhaust manifold which is configured to be connected to a cylinder of the internal combustion engine, an exhaust pipe which is provided on a downstream side of an exhaust flow from the exhaust manifold, a connection member including a flange portion which connects the exhaust pipe and the exhaust manifold to each other and a boss portion which is provided integrally with the flange portion and is fixed to a portion of an outer circumferential surface of the exhaust pipe, a sensor which is attached to the boss portion and is configured to detect components of the exhaust, and a purification device which is connected to a downstream end of the exhaust pipe and is disposed on a side opposite to the boss portion with respect to the exhaust pipe.

Abstract: An engine includes a side wall, a head cover, and a cam cover. The cam cover is disposed obliquely relative to the side wall. The cam cover has a seal line that seals up a gap between the head cover and the cam cover. The engine further includes a cam cap fixed to an upper surface of the side wall to support a camshaft so as to be rotatable between the side wall and itself.

Abstract: An engine includes: an oil control valve built in a cylinder head, and configured to control a pressure of oil to be supplied to a variable valve mechanism via a camshaft; and a cam cap fixed to an upper face of the cylinder head, and configured to rotatably support the camshaft between the cam cap and the cylinder head, as a flow passage for the oil to be force-fed from an oil pump to the oil control valve, the cam cap including: a lateral passage formed inside the cam cap, and extended in a direction along the upper face of the cylinder head; and a downward passage extended downward from the lateral passage so as to serve as a downstream side flow passage of the lateral passage, and configured to guide the oil toward the oil control valve.
