A pair of output transistors forming a single-ended push-pull circuit are alternately turned on and off at a vertical cycle to supply a vertical deflection current to a vertical deflection yoke. A low voltage winding is wound on a horizontal flyback transformer connected to a horizontal output transistor. First and second rectifying circuits are provided for rectifying and filtering a horizontal scan period portion and a horizontal flyback portion, respectively, of the voltage developed across the winding, and d.c. outputs of the rectifying circuits are fed to the push-pull circuit as operating power therefor. The first rectifying circuit includes a capacitor-input filter circuit while the second rectifying circuit includes a choke-input filter circuit, a critical current of which choke-input filter is established between a maximum current and a minimum current required for the push-pull circuit.

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.

A beam-indexing color television receiver having a phosphor screen including one index stripe for every predetermined integral number of phosphor stripe sets each including a red, a green and a blue phosphor stripe. The minimum bias current is supplied to the picture tube only upon detection of a chrominance signal within a predetermined hue range around a specific chrominance signal corresponding to the phosphor stripe which is in the middle between adjacent index stripes on the phosphor screen, thus attaining a superior color saturation and contrast.
摘要:
An object of the present invention is to provide a copper surface treatment method capable of keeping certainly a bonding strength between a copper surface and a resist, or between a copper surface and an insulating resin without forming irregularities having sizes of more than 1 μm on the copper surface, and a copper treated with the method. The surface treatment method, comprising: a first step of forming, on a copper surface, a nobler metal than the copper discretely; a second step, subsequent to the first step, of forming copper oxide on the copper surface by oxidation with an alkaline solution containing an oxidizing agent; and third step of dissolving the copper oxide so as to be removed, thereby forming irregularities on the copper surface.
