Abstract: A liquid ejection head includes a print element substrate including multiple ejection openings, pressure chambers, a common flow path, and pumps, the pumps being configured to circulate liquid between the common flow path and the pressure chamber; and a flow path member laminated to the print element substrate. The flow path member includes a supply flow path and a collection flow path, the supply flow path being configured to supply liquid to the print element substrate, and the collection flow path being configured to collect liquid that is not ejected. The supply flow path and the collection flow path have liquid connection with the same common flow path. A circulating pump generates a flow of liquid flowing in an order of the supply flow path, the common flow path, and the collection flow path, the circulating pump being provided at a position different from the print element substrate.

Abstract: A catalyst deterioration determination system effectively prevents erroneous determination caused by increase of the H2 component in exhaust gas and improves accuracy of determination. A LAF sensor and an O2 sensor are provided on the upstream side and downstream side of a three-way catalyst. Deterioration of the three-way catalyst is determined on the basis of an output of the O2 sensor, which is detected during air-fuel ratio switching control in which an air-fuel ratio is alternately switched to the rich side and lean side of the stoichiometric air-fuel ratio according to a detected equivalent ratio detected by the LAF sensor, on the basis of a result of comparison between an oxygen inflow into the three-way catalyst and a lean side-limiting value and a rich side-limiting value which are target values of the oxygen inflow. Fuel injection timing retardation control and/or divided fuel injection control are prohibited during the deterioration determination.

Abstract: A heater unit mounted on a tray utilizes a PTC heater 100 having a positive temperature coefficient (PTC), and a sheet heater 200 superposed thereto. The PTC heater 100 includes PTC members 150 buried within an insulating substrate 130, and on both sides of the PTC members are placed copper foils 120, 122 functioning as electrodes. When the PTC heater 100 is heated up to a preset temperature, the electric resistance of the heater is increased greatly, and the heating is stopped, maintaining the preset temperature. The sheet heater 200 contributes to reduce the time the heater needs to rise to the preset temperature during initial startup.

Abstract: A heating roller 10 comprises a surface layer 157 formed of a prepreg material including carbon fibers having a high tensile strength and a high elastic modulus, and a heating unit 153 mounted in the inner area of the surface layer and communicated to a power supply unit 30 formed of a prepreg material including carbon fibers having a high electric resistance. A metal material working as an electrode 20 communicated to the power supply unit 30 and the heating unit 153 is mounted to both ends of the heating roller 10. The electric resistance of the heating unit 153 is adjusted either by changing the thickness (number of laminated layers) of the prepreg material including carbon fibers, or by adjusting the mounting angle of the carbon fibers inside a prepreg material being laminated and the angle of the carbon fibers inside another prepreg material being laminated.
