  • Patent number: 11168650
    Abstract: An engine EGR system is provided, which includes an engine body, an intake passage, an exhaust passage and an EGR passage configured to recirculate exhaust gas as EGR gas to the intake passage. The EGR passage includes an EGR cooler and an EGR internal passage constituting the EGR passage upstream of the EGR cooler, and including a passage passing through a cylinder head. The EGR internal passage has a bent pipe part including a first bent portion at which an upstream portion of the EGR internal passage is bent away from a gas inflow port of the EGR cooler, a second bent portion located downstream of the first bent portion and bending the EGR internal passage toward the gas inflow port, and an intermediate portion connecting the first and the second bent portions by being disposed therebetween. The water-cooling passage is disposed around the bent pipe part.

  • Patent number: 10987885
    Abstract: A tube material is formed by continuously extruding a thermoplastic resin material in the shape of a cylinder that has a thickness of 100 ?m and a circumferential length of 800 mm. After that, in a polishing process, the tube material is rubbed with a lapping tape of #2000 while being rotated in one direction at a fixed speed, so that circumferential stripes are formed on the outer circumferential surface of the tube material. Then, the circumferential stripes are thermally transferred by pressing the outer circumferential surface of the heated tube material against a mold surface that is finished in the shape of circumferential stripes by a thermal transfer process.

  • Patent number: 9055615
    Abstract: The present invention provides an induction heating cooker, which is structured to cut off visible light being incident upon an infrared sensor, yet being capable of more accurately sensing any abnormality of the infrared sensor before heating is started. To this end, the induction heating cooker includes a sensor failure sensing-purpose light emitting portion that emits visible light for sensing any failure of an infrared sensor, a visible light cutting filter provided on a surface of a printed circuit board holding the infrared sensor so as to cover the field of view of the infrared sensor, and a control unit that limits the output of an inverter circuit supplying a high-frequency current to a heating coil when the output of the infrared sensor is equal to or less than a threshold value in a situation where the sensor failure sensing-purpose light emitting portion is lit up.

  • Patent number: 8796599
    Abstract: An induction heat cooking device is provided that finishes preheating in a short time and maintains the temperature obtained at the finish of the preheating. When a preheating heating mode is selected as an operation mode, a control unit (8) arranged in the induction heat cooking device starts operation in a preheating mode in which a cooking container is heated with a first heating output. When an increment of an output value of an infrared sensor exceeds a first predetermined increment since the heating starts with the first heating output, the control unit causes a notification unit to notify a user that the preheating is finished, and the operation mode is changed to a waiting mode for performing heating with a second heating output that is lower than the first heating output. Further, when the user sets a heating power by means of a heating power setting unit in the preheating mode, the control unit prohibits changing to the heating power set by the user.
