A scanning speed modulating apparatus for a television receiver. A differentiated signal derived by differentiating a video signal is supplied to a horizontal deflecting coil, so that a current having a waveform corresponding to that of the differentiated signal and superposed on a horizontal deflecting signal flows through the horizontal deflecting coil.

A video display system that includes a housing has arranged thereon a plurality of video input terminals for receiving a plurality of video signals having different scanning frequencies. An expansion/compression processing circuit replaceably mounted on the housing receives and expands/compresses the plurality of video signals and produces at least one video signal expanded/compressed in synchronism with a sync signal selected by a sync switching circuit. At least one of the video signals is synthesized with another video signal, and the synthesized video signal is produced by a video signal synthesis circuit. A video signal from the video signal synthesis circuit is used to generate a video display signal in synchronism with the sync signal. This video display signal is applied to a display. At least one such video display system, an AV controller, a central control console and a lecture table are combined to realize a screen display system.

In order to enable sampling of high definition still video signals in addition to common video signals, a function is added for sampling video signals with every other plurality of picture elements as an interval to an image processing apparatus without using a sampling circuit which requires high speed operations. The invention is also intended to change over between two circuits that is, a circuit for using a picture element clock regenerated by a PLL circuit as a sampling clock for analog to digital converters and a circuit for using a clock obtained by dividing the picture element clock as a sampling clock for the analog to digital converters to sample video signals with every other plurality of picture elements as an interval. Thus, it is possible to carry out sampling of high definition video signals with high frequencies in addition to common video signals without necessity of raising the operating speed of the sampling circuit.

Disclosed is a chroma scanning circuit used in a beam index type color picture reproducing apparatus, the circuit being provided with an inductance element connected in series to a horizontal deflection coil, and a scanning signal generation circuit connected to a junction between the horizontal deflection coil and the inductance element. The impedance between the junction and the earth at the chroma scanning frequency is increased by the inductance element to thereby make a chroma scanning signal generated from the chroma scanning signal generation circuit flow easily in the horizontal deflection coil.

A semiconductor package substrate is provided, which can meet the move toward high integration of semiconductors. A nickel layer is plated on an electroplated copper foil to form a wiring pattern. An LSI chip is mounted on the copper foil, and terminals of the LSI chip and the wiring pattern are connected by wire bonding, followed by sealing with a semiconductor-sealing epoxy resin. Only the copper foil is dissolved away with an alkali etchant to expose nickel. With a nickel stripper having low copper-dissolving power, the nickel layer is removed to expose the wiring pattern. A solder resist is coated, and a pattern is formed in such a way that connecting terminal portions are exposed. Solder balls are placed at the exposed portions of the wiring pattern and are then fused. The wiring pattern is connected to an external printed board via the solder balls.

A case of a stepping motor is divided by a partition. One of divided portions of the case contains a rotor and a stator of the stepping motor. A small-sized drive gear is fixed to a drive shaft integrally rotated with the rotor. The drive gear is meshed with a larger gear of a transmission gear. This transmission gear includes a smaller gear integrally rotated with the larger gear. The smaller gear is meshed with a large-sized output gear fixed to an output shaft of the stepping motor. Two pairs of the reduction gear mechanisms transmit a rotation of the drive shaft to the output shaft in a reduced state.

In a display panel including a plurality of signals lines along a column direction and a plurality of scanning lines along a row direction for applying a display signal to display elements forming pixels arranged in a matrix form of rows and columns on a substrate, a switching arrangement for connecting at least two display elements to a signal line in each row is line-sequentially scanned by the scanning lines so that the display signal is time-serially applied through the same signal line to each of the at least two display elements connected to that signal line. Thereby, total number of the signal lines can be reduced to a value equal to or smaller than the number of display elements in the row direction.
