An ink jet head accomplishes high quality recording for a long term by an improved liquid repellency treatment. This liquid repellency treatment is applied to at least a peripheral portion of a discharge port on an ink discharge port forming surface of the ink jet head. A mixture of a fluorine-containing high polymer compound and a compound having fluorine substituted hydrocarbon group and a silazane group, alkoxysilane group or halogenized silane group is employed as a liquid repellent agent.

An improved solid state image sensing device includes a two-dimensional array type charge-coupled device. The read rate thereof is increases n times a standard read rate, where n is a positive integer larger than one, and the output signals of the charge-coupled device are added n times with respect to the same pixel or to the same combination of pixels. The sum of the addition stored in a memory is read at the standard read rate, so that the dynamic range of the solid state image sensing device is expanded.

A bell signal generating circuit for a key telephone set. A dc component of a pulse signal is removed by a photo-coupler to generate a first signal. A high frequency component of the first signal is removed by a filter to generate a second signal. A differential amplifier amplifies the second signal to generate a bell signal. To the differential amplifier, a dc supply voltage based on the dc signal in synchronism when the pulse signal is applied.

A thin-film magnetic head comprises a floating slider provided with two pairs of recesses, a pair of thin-film magnetic head elements formed between the two pairs of recesses on the end surface of the floating slider, and terminals formed by filling up the recesses of the floating slider with a conductive material. Each terminal has a front surface exposed in the end surface of the floating slider, and a side surface exposed in the side surface of the floating slider adjacent to the end surface of the same. Lead wires are connected respectively to the side surfaces of the terminals exposed respectively in the side surfaces of the floating slider. The thin-film magnetic head is one of a plurality of thin-film magnetic heads obtained by dicing a substrate on which a plurality of pairs of thin-film magnetic head elements are formed into a plurality of floating sliders each carrying a pair of thin-film magnetic head elements. When the substrate is diced, the side surfaces of the terminals are exposed in the side surfaces of each floating slider.
