An in-cylinder pressure detecting device of a direct injection type internal combustion engine is provided in which a ring-shaped pressure detection element (34) surrounding a fuel injection hole (33b) is provided in the vicinity of an extremity of an injector (20) that injects fuel into a combustion chamber. Since the pressure detection element is provided on the injector, not only is it unnecessary to change the shape or structure of the cylinder head or the combustion chamber in order to provide the pressure detection element, but it is also possible to cool the pressure detection element (34) by fuel passing through the inside of the injector to thus enhance the precision of pressure detection and the durability. Further, since the ring-shaped pressure detection element (34) surrounds the periphery of the fuel injection hole (33b), it is possible to maximize the dimensions of the pressure detection element (34) to thus further enhance the precision of pressure detection while avoiding interference between the pressure detection element (34) and fuel injected via the fuel injection hole (33b).

An induction heating cooker includes an inverter for supplying a current to a heating coil, a control portion for driving the inverter, an electrostatic capacitance detecting portion for measuring electrostatic capacitance of a plurality of electrodes, and a boiling over detecting portion. The boiling over detecting portion reduces an output of the inverter from a first set value to a second set value after a sensed value of the electrostatic capacitance is within a first variation range (ΔV1) or more, and returns the output of the inverter to the first set value when a sensed value during a boiling over establishing period (T2) performed after the sensed value has reached the first variation range or more and falls within a second variation range (ΔV2).

摘要:
A repeater device comprises a determining section for determining whether the authentication with the sink device fails continuously for a predetermined time or more; a repeater information rewriting section for, when the determination is made that the authentication with the sink device has failed continuously for the predetermined time or more, rewriting the repeater information stored in the storage section into information indicating the sink device; and a second authenticating section for causing the source device to obtain the repeater information rewritten into the information indicating the sink device, and causing the source device to authenticate the repeater device.
摘要:
A linear heater is formed of an enamel wire composed of a heating wire and an enamel layer. The heating wire is made of a copper alloy containing silver, for example. The enamel layer is made of polyester imide (PEI), polyimide (PI) or polyamide imide (PAI), for example. The enamel layer is coated with an insulating coating layer. The insulating coating layer is made of fluororesin such as perfluoroalkoxy mixture (PFA), polyimide (PI), or polyamide imide (PAI). The linear heater is bonded to the lower surface of an upper toilet seat casing such that it is sandwiched between a metal foil and a metal foil made of aluminum, for example.
