Abstract: Disclosed is a replay apparatus including a reading unit, a display control unit, a storage unit to store a predetermined display limited letter string and a judging unit to judge whether the predetermined display limited letter string stored in the storage unit exists in the letter string which is based on the text data constituting the predetermined replay data read by the reading unit or not, and when the judging unit judges that the predetermined display limited letter string stored in the storage unit exists in the letter string which is based on the text data constituting the predetermined replay data read by the reading unit, the display control unit carries out a predetermined process to the judged display limited letter string in order not to display the judged display limited letter string in the predetermined display apparatus.
Abstract: Provided is a heating temperature adjustment circuit in a thermal flow meter capable of adjusting fluctuations of a heating temperature of a heat-generating resistor due to fluctuations of resistances with high accuracy and low cost. The thermal flow meter comprises: a heat-generating resistor that generates heat when a current flows therethrough; a first temperature measuring resistor, a second resistor, a third resistor, and a fourth resistor whose resistance values vary due to temperature; and a fixed resistance having a resistance temperature coefficient lower than that of the first temperature measuring resistor, and measuring a flow rate of a fluid by controlling the heating temperature of the heat-generating resistor.
Abstract: A valve plate includes a cooling medium duct for a compressor used for generating compressed air. From the perspective of a piston chamber of the compressor, at least part of the cooling medium duct extends between the piston chamber and an air discharge valve that is arranged in the valve plate. A method for cooling compressed air in a valve plate of a compressor is also provided.
Abstract: An acoustic processing device includes an input section to which audio signals of a plurality of channels respectively including in-phase components are input, a phase adjusting section that adjusts phases of the audio signals of the plurality of channels respectively to generate phase adjustment signals of the plurality of channels being different in phase from the audio signals of the plurality of channels input to the input section, an anti-phase generating section that generates an anti-phase signal by adding the phase adjustment signals of the plurality of channels to each other and adjusting a phase of the added signal to a substantially inverted phase, and an output section that outputs signals obtained by adding, to each of the audio signals of the plurality of channels input to the input section, the phase adjustment signal of another channel and the anti-phase signal.

Abstract: An outboard drive for a boat, having an electric motor, a power supply line and a contact-making apparatus, connected to the power supply line for connecting a DC voltage source. The outboard drive has a space for accommodating the DC voltage source. The contact-making apparatus has a first and a second contact stage, and a current limitation element is connected between the DC voltage source and the power supply line in the first contact stage.
Abstract: A system has a compressor and a consumer which are coupled to a drivetrain and extract energy through the drivetrain. The consumer is suitable for varying an absorption of power, which is made available to it by the drivetrain, as a function of a power which is required for compressor operation and which is supplied from the drivetrain to the compressor. A pump has at least one pump chamber which generates a pumping power during pumping operation. The pump additionally has at least one pump chamber which generates no pumping power or a reduced pumping power during pumping operation.
Abstract: A hydraulic circuit for a hydraulic working machine is composed of a main pump 21, a boom cylinder 11 arranged for extension or contraction by pressure oil from the main pump 21, a directional control valve 22 for controlling flows of pressure oil to be fed from the main pump 21 to a bottom chamber 11a and rod chamber 12b of the boom cylinder 11, a control unit 23 for performing a change-over control of the directional control valve 22, a pilot pump 24, a jack-up selector valve 25 for controlling a flow of pressure oil delivered from the pilot pump 24, a flow control valve 26 connected on an upstream side of the directional control valve 22 to a meter-in port of the directional control valve 22 such that the flow control valve 26 can be changed over by the jack-up selector valve 25, and a center bypass selector valve 27 connected on a downstream side of the directional control valve 22 to a center bypass port of the directional control valve 22 such that the center bypass selector valve 27 can be changed over

Abstract: An internal combustion engine control apparatus according to the present invention includes storage for storing a plurality of air flow rate conversion tables T1 and T2 used to convert a signal of a heating resistor 2 to an air flow rate, a selector for selecting a conversion table to be referred to from the plurality of conversion tables T1 and T2 stored, and a converter for converting a signal of the heating resistor into an air flow rate by referring to the conversion table selected by the selector. The selector performs selection of the conversion table according to a state value, which directly or indirectly indicates the state of air flow pulsation generated in a passage.
Abstract: A method and apparatus for attenuating fuel pump noise in a direct injection internal combustion engine. In one proposal, the direct injection fuel nozzle is suspended from a fuel rail in a fashion that avoids direct metal-to-metal contact between the injector and the engine block. The direct injection nozzle may also be connected to the fuel rail by a pair of spaced-apart seals which equalize the longitudinal pressure on the nozzle during operation. Enlarged diameter fuel reservoirs and/or a restricted orifice may be provided fluidly in series between the fuel pump and the direct injection nozzle in order to attenuate noise resulting from fuel pump pulsation.
