摘要： An infrared sensor includes a series capacitor element and a reference capacitor element each exhibiting a predetermined capacitance value; an infrared-detecting capacitor element whose capacitance value varies depending on an intensity of infrared light incident on the element; and an output node being a node at which a first terminal of the series capacitor element, a first terminal of the reference capacitor element and a first terminal of the infrared-detecting capacitor element are connected to one another. A potential of the output node is brought to a reference potential by applying a predetermined voltage between a second terminal of the series capacitor element and a second terminal of the reference capacitor element; a potential of the output node is brought to a detection potential by applying the predetermined voltage between the second terminal of the series capacitor element and a second terminal of the infrared-detecting capacitor element; and the intensity of infrared light is output as a potential difference between the reference potential and the detection potential.

摘要： An optical writing apparatus including a semiconductor laser having plural light emitting elements and a single light-receiving element and plural semiconductor laser drive controlling devices. The plural light emitting elements in the semiconductor laser array are driven such that an optical writing operation at a same time per each of plural lines is performed. A commonly used LD drive controlling circuit drives the LD array. An output timing-determining device outputs a switch changing-over signal to either one of respective changing-over switches in a changing-over switch circuit. After an operational delay time of the changing-over switch elapses, an APC signal is output to an APC control section of the LD drive controlling circuit connected to a negative feedback loop formed by a changing-over operation of the changing-over switch circuit. After the completion of the APC operation, the outputting of the switch changing-over signal to the changing-over switch is stopped.

摘要： Each of a pair of magnetic core halves includes a substrate and a thin magnetic metal film formed on the substrate. The substrate is notched with a winding groove. The pair of the magnetic core halves are integrally bonded to each other so that a gap filling film is formed between the facing surfaces of the thin magnetic metal films. The zero depth position of the magnetic gap which is determined by the length of the facing thin magnetic metal films is offset to a magnetic recording medium sliding surface of the magnetic head from the notching start position of the winding groove on the side of the magnetic gap. Hence, the shape of the thin magnetic metal film exposed on the magnetic recording medium sliding surface is maintained constant from the initial position to the depth zero position.
