Abstract: A burner device for supplying a mixture of a fuel gas and a combustion-supporting gas into a combustion region includes: a mixing path configured to inject the mixture from a downstream end portion of the mixing path into the combustion region; a fuel gas injection nozzle configured to inject the fuel gas into the mixing path toward the combustion region; and a combustion-supporting gas supply swirler configured to inject the combustion-supporting gas such that at least a part of the combustion-supporting gas collides directly with the fuel gas injected from the fuel gas injection nozzle, in a direction of a tangent line that is tangent to a fuel injection hole of the fuel gas injection nozzle on a cross-section.

Abstract: A chassis with noise cancellation function which performs active noise cancellation in a first location for cancelling a noise generated in the chassis includes a sound receiving circuit receiving a surrounding sound in a second location, a memory circuit storing noise cancellation sound data and the surrounding sound that are associated with each other, a controller selecting the noise cancellation sound data corresponding to the surrounding sound received by the sound receiving circuit from the memory circuit and generating a noise cancellation signal based on the selected noise cancellation sound data and a sound output unit outputting a noise cancellation sound in said first location based on the noise cancellation signal to perform the active noise cancellation.

Abstract: A semiconductor integrated circuit device constituted by a plurality of sets each of which having a pair of memory mats and each memory mat having a plurality of memory cells arranged in a matrix and a sense amplifier, I/O lines for transmitting signals provided by the sense amplifiers, selecting circuitry for selecting either a condition for sending out the signals provided by the sense amplifiers on the I/O lines or a condition for not sending out the same on the I/O lines, and Y-selection lines for transmitting the selection signals. A decoder connected with selection is disposed substantially at the middle of the Y-selection lines. X- and Y-address buffers are disposed close to each other nearer to the center of the chip than X- and Y-redundant circuits. A reference voltage generating circuit is disposed nearer to the edge of the chip than an output buffer circuit. A relief selecting circuit of each memory mat is formed adjacent to a redundant line selecting circuits included in the same memory mat.

Abstract: A temperature control apparatus for use in a refrigerating machine, wherein an a.c. control element and the solenoid coil of a holding type solenoid are connected in series in an a.c. power circuit, the holding type solenoid serving to actuate a damper for opening and closing the outlet for ejecting cooled air into the refrigerating chamber, and also a temperature sensor for detecting the temperature in the refrigerating chamber and a triggering circuit for triggering the a.c. control element are provided in the a.c. power circuit. The triggering circuit supplies a trigger signal to the control electrode of the a.c. control element at a predetermined period in synchronism with the phase of the current from the a.c. power source in response to the output of the temperature sensor, so that the solenoid coil is energized to drive the damper.

Abstract: An automatic washing machine which automatically carries out the steps of washing, rinsing and dehydrating in accordance with a preselected program, comprises an indication means for indicating the occurrence of abnormal operation if it occurs in the steps of washing, rinsing and dehydrating, in such a manner that the indication mode differs from cause to cause of the occurrence of the abnormal operation.
