摘要:
An image display system includes a display device, an input section to which video signals of an interlace scanning system are inputted, a signal converter section which increases horizontal scanning lines of the inputted video signals in number by a factor of at least two, and which generates first and second fields, each of the fields including effective scanning lines used for displaying and ineffective scanning lines not used for displaying, with the effective and ineffective scanning lines being arranged alternately in each of the fields, and a display control section which controls the display device to display the first and second fields alternately. The display control section controls the display device such that positions of the effective scanning lines of the first fields correspond with those of the ineffective scanning lines of the second fields, and vice versa.

An image display system includes a memory for storing at least one scanning line of an inputted video signal of the interlace scanning system, and reading means for repeating to read the video signal of one scanning line from the memory at a speed which is n (n is an integer of 2 or more) times of the writing speed of the video signal for the memory for a horizontal scanning period which is 1/n of the writing period and to stop reading for a horizontal scanning period of the remaining (n−1)/n for each scanning line of one field which is sequentially inputted and reading each scanning line so that the continuous fields interpolate the period of stopping of reading from the memory each other.

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.
