    摘要: A coupling member 180 of a glow plug 100 includes a first bend 183 and a second bend 184 folded in an axis direction OD and a joint section 185 in a tapered shape configured to connect the first bend 183 with the second bend 184 and reduce the diameter toward a rear end side of a body portion. Accordingly, in a limited space formed between a housing 130 and a heater unit 150, this configuration increases the length of the coupling member 180, compared with a configuration without any bend folded in the axis direction OD. This results in decreasing the spring constant k of the coupling member 180 and suppressing extension of the coupling member 180 in the axis direction due to thermal expansion. This accordingly prevents an unnecessary load due to the extension of the coupling member 180 in the axis direction from being applied to a pressure sensor 160 via the heater unit 150 and improves the measurement accuracy of the pressure sensor 160.

    摘要: An object is to provide an output correction apparatus which can correct offset drift of a cylinder internal pressure sensor, and a cylinder internal pressure detection apparatus which can accurately detect cylinder internal pressure of an internal combustion engine through use of the output correction apparatus. A cylinder internal pressure detection apparatus 12 includes a detection circuit section 200 which detects a change in the resistance of a piezoresistor element 138 as an electrical signal; an amplification circuit section 201 which amplifies and outputs the electrical signal (output value); and a correction circuit section 202 which corrects the output value. The correction circuit section 202 is composed of a reset control section 205 which resets the output value of the amplification circuit section 201 to a reference value, and a reset timing detection section 206 which determines a timing of the resetting. The reset timing detection section 206 measures the waveform period of an output waveform output from the amplification circuit section 201, calculates the reset timing on the basis of the waveform period, and outputs a reset signal to the reset control section 205 at the reset timing.
