摘要： An apparatus for detecting concentrations of a plurality of gas components has a single polarographic sensor capable of detecting an oxygen concentration and a composite concentration of oxygen gas, carbon dioxide gas and steam. A first voltage is applied to the polarographic sensor which then measures only the oxygen concentration, or a second voltage is applied to the sensor which then measures only the composite concentration of oxygen gas, carbon dioxide gas and steam. The first and second voltages are applied to the sensor in a time division manner. Upon application of first and second voltages in such a time division manner, corresponding currents flowing through the sensor are detected to obtain signals corresponding to the oxygen concentration and the composite concentration of oxygen gas, carbon dioxide gas and steam. The signal corresponding to the oxygen concentration is subtracted by an operational amplifier from the signal corresponding to the composite concentration of oxygen gas, carbon dioxide gas and steam, thereby obtaining a signal representing a composite concentration of carbon dioxide gas and steam.

摘要： A temperature control apparatus detects an actual temperature of an object (e.g., sensor) to be controlled, and compares the actual temperature with a preset target temperature to obtain a difference therebetween, thereby keeping a heater temperature constant. The temperature control apparatus has a temperature rise rate limiter for controlling a temperature rise rate of the object to be controlled so as not to exceed a predetermined temperature rise rate. The object may thus not be damaged by thermal strain which results from a high temperature rise rate.

摘要： A sound reproduction system includes an electro-acoustic transducer and a transducer driver for driving the electro-acoustic transducer. The transducer drive includes a filter which is configured to reproduce at a listener's location an approximation to the local sound field that would be present at the listener's ears in recording space, taking into account the characteristics and intended position of the electro-acoustic transducer relative to the listener's ears. The electro-acoustic transducer includes a first sound emitter which provides an intermediate sound emission channel, and second and third sound emitters providing respective left and right sound emission channels. The first sound emitter is located intermediate of second and third sound emitters. Higher frequencies from at least one of the second and third sound emitters are transmitted closer to the first sound emitter while lower frequencies are transmitted away from the first sound emitter.
