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： 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： Several encoders perform a local decoding of a speech signal and extract excitation information and vocal tract information from a speech signal for an encoding operation. The transmission rate ratio between the excitation information and the vocal tract information are different for each encoder. An evaluation/selection unit evaluates the quality of decoded signals subjected to a local decoding in each of the encoders, determines the most suitable encoders from among the several encoders based on the result of the evaluation, and selects the most suitable encoder, thereby outputting the selection result as selection information. The decoder decodes a speech signal based on selection information, vocal tract information and excitation information. The evaluation/selection unit selects the output from the encoder in which the quality of a locally decoded signal is the most preferable. When vocal tract information changes little, the vocal tract information is not output, thereby allowing for increased quality of information. As much of the surplus of unused vocal tract information as possible is assigned to a residual signal. Thus, the quality of a decoded speech signal is improved.

摘要： Provided is a robot capable of appropriately adjusting a position and the like of a main body in view of executing a specified task involving an interaction with a target object. While the position and posture of the main body (10) are being controlled according to a second target path, the robot (1) moves from a first specified area to a second specified area and stands there. In this state, a second position deviation (=the deviation of the position of the main body from a second target path) and a second posture deviation (=the deviation of the posture of the main body from a second target posture) are determined. According to the determination result, the second target path is corrected so that the subsequent position deviation and the like may be smaller.

摘要： Embodiments of the present invention help to prevent a head characteristic from being deteriorated by re-deposition or damage which occurs when a sensor film is etched, a track width is narrowed, and the head characteristic is stabilized. According to one embodiment, when it is assumed that the thickness of the sensor film on an air bearing surface is T, and a distance between an end of a medium layer that is interposed between a free layer and a pinned layer which comprise the sensor film and an end of the sensor film lowest portion, a relationship of 1.2×T≦X≦2.5×T is satisfied, and the ends of a pair of magnetic films which are in contact with both sides in the track-width direction through an insulator do not exist in the track central portion from the free layer end. The sensor film is etched while an incident angle of an etching beam is changed over, and when it is assumed that a direction normal to the sensor film surface is the incident angle of 0, etching is conducted under the condition where the incident angle of the etching beam becomes smaller with time.
