摘要： A pressure sensor-incorporating spark plug including a groove 17e for accommodating an output cable 27 formed on a side surface of a hexagonal portion 17a. A U-shaped member is bent into a tubular shape to obtain a fixing member 31. After the fixing member 31 and the output cable 27 passing through the fixing member 31 are placed in the groove 17e, the fixing member 31 is crimped in the direction of the arrow shown in FIG. 5(a), so that the fixing member 31 is deformed to fit the wall surface of the groove 17e. Thus, the output cable 27 is nipped by the fixing member 31, and the fixing member 31 is held within the groove 17e of the hexagonal portion 17a. As a result, the output cable 27 is fixed to the hexagonal portion 17a.

摘要： An object of the present invention is to provide a charge amplifier which can be operated at low cost so that electric charge generated in a piezoelectric pressure sensor having one end grounded is converted into a voltage signal.In the charge amplifier (1) according to an embodiment of the present invention, a plus side power source input terminal of an operational amplifier (5) is connected to a plus power source (+5 V) while a minus side power source input terminal of the operational amplifier (5) is grounded, so that the operational amplifier (5) is supplied with a single power source. Further, an offset voltage lower than the plus power source voltage but higher than the ground potential is applied to a non-inverted input terminal of the operational amplifier (5). Accordingly, change of pressure in both positive and negative directions can be converted into a voltage signal with the offset voltage as its center though the operational amplifier (5) is driven by a single power source. That is, cost can be suppressed because a double power source is not required.
摘要翻译：本发明的目的是提供一种可以以低成本操作的电荷放大器，使得在具有一端接地的压电式压力传感器中产生的电荷被转换为电压信号。在根据本发明的实施例的电荷放大器（1）中，运算放大器（5）的正侧电源输入端连接到正电源（+ 5V），而负侧电源输入端运算放大器（5）接地，使得运算放大器（5）被提供有单个电源。此外，低于正电源电压但高于接地电位的偏移电压被施加到运算放大器（5）的非反相输入端子。因此，通过运算放大器（5）由单个电源驱动，正负方向的压力变化可以转换为以偏移电压为中心的电压信号。也就是说，可以抑制成本，因为不需要双电源。

摘要： A misfire deciding method for an internal combustion engine, which can be executed conveniently at low cost by using a gasket type pressure sensor and which can decide a misfire highly accurately and reproducibly. The internal pressure of an internal combustion engine having a spark plug mounted therein is measured by a pressure sensor (or a gasket type pressure sensor) mounted in the mounting seat of the spark plug. The measured information of the internal pressure for a period (or a before top dead center period) after an intake valve is closed and before the crank angle reaches top dead center is used as the before top dead center pressure information, and the measured information of the internal pressure for a period (or an after top dead center period) after the crank angle reaches the top dead center and before an exhaust valve is opened is used as the after top dead center pressure information. Misfire of the internal combustion engine is decided on the basis of misfire decision information obtained using the before top dead center pressure information and the after top dead center pressure information.

摘要： A process for hydrogenating carbon dioxide to generate methanol. In the process, a strip of copper base plate is transported by the groups of rotating drive rollers to deposit porous metallic zinc on the copper base plate. Hydrogen is generated from the porous metallic zinc upon electrochemical reactions in the inner space sealed with the above groups of rollers. Simultaneously, zinc oxide and copper oxide catalysts are formed on the porous metallic zinc. Carbon dioxide is introduced into the sealed inner space under high-temperature and high-pressure to generate methanol by hydrogenation.

摘要： A glow plug in which a convex portion (70) is formed in an outer peripheral surface (10b) of a heater (10) in a part facing an inner peripheral surface (137b) of a leading end part (137) of a housing (110) and interposed in a leading end side annular gap K1, so as to maintain a gap with the inner peripheral surface (137b). A decline in detection accuracy can be prevented to the extent that combustion gas can be received by the leading end (72) of the convex portion (70) even if soot clogging should occur.
