Disclosed are a porous membrane which is made from a material containing, as its main component, a polytetrafluoroethylene resin, and a method of producing a porous membrane comprising forming a hollow or sheet-like film from a mixture of a polytetrafluoroethylene resin dispersion and a fiber-forming polymer, heat-treating the film at a temperature not lower than the melting temperature of the resin, and removing the fiber-forming polymer. Production of polytetrafluoroethylene porous membranes of a variety of pore sizes and porosities is possible by suitably varying the type and amount of additives added to an original liquid. The membrane finds spreading use in the field of separation in high-temperature and strong decomposing or strong dissolving mediums.

An angular velocity sensor including a vibration body having a sensor electrode, a driving electrode, and a monitor electrode. The monitor electrode generates a signal according to vibration of the vibration body. The sensor circuit outputs a signal representing an angular velocity applied to the vibration body. The amplitude determination circuit measures amplitude of vibration of the vibration body. A PLL circuit includes a constant voltage source for generating a constant voltage, a timing switching unit for outputting a voltage by switching selectively between the constant voltage and a voltage corresponding to the monitor signal, and a voltage-controlled oscillator for outputting an oscillation signal having a frequency corresponding to the voltage output from the timing switching unit. When the amplitude measured is smaller than a predetermined value, the timing switching unit outputs the constant voltage output from the constant voltage source and outputs a start-up mode signal.

Provided is a control apparatus for an internal combustion engine, which can adequately perform the control of a fuel injection amount even when an abnormality, a disconnection or the like of a fuel pressure sensor occurs and thereby accurate fuel pressure information is not able to be obtained.A fuel injection valve (26) is provided which is capable of directly injecting fuel into a cylinder. If a target fuel injection amount is smaller than a minimum fuel injection amount that is minimum and is capable of injecting during one opening and closing operation of the fuel injection valve (26), the start timing of fuel injection is set within a period in which an exhaust valve is opened during an exhaust stroke.

An angular velocity sensor includes a vibration body having a sensor electrode, a driving electrode, and a monitor electrode. The monitor electrode generates a signal according to vibration of the vibration body. The sensor circuit outputs a signal representing an angular velocity applied to the vibration body. The amplitude determination circuit measures amplitude of vibration of the vibration body. A PLL circuit includes a constant voltage source for generating a constant voltage, a timing switching unit for outputting a voltage by switching selectively between the constant voltage and a voltage corresponding to the monitor signal, and a voltage-controlled oscillator for outputting an oscillation signal having a frequency corresponding to the voltage output from the timing switching unit. When the amplitude measured by the amplitude determination circuit is smaller than a predetermined value, the timing switching unit outputs, to the voltage-controlled oscillator, the constant voltage output from the constant voltage source and outputs a start-up mode signal. This angular velocity sensor has a stable output characteristic.
