Abstract: A method of animated yarncraft instruction includes providing a digital graphic file having a video object and an animated image object within the file. The animated image object is instructional of needlework and corresponds to the video object. Moreover, the animated image object represents individual steps taken for producing a yarncraft project, which is usable to advantage by a needlework hobbyist without resorting to or requiring an understanding of a needlework chart.

Abstract: The present invention relates to a plasma display apparatus and driving method of the same. Since wall charges are remained without performing an additional erasing discharge after the sustain period is terminated and before the initiation of the reset period, the set up discharge can be generated with a small voltage during the reset period to obtain the margin of the driving voltage. In particular, since the highest voltage of the reset period during other subfields is lower than the highest voltage of the reset period of a subfield implementing a low gray scale, with inducing the half discharge before the set up discharge in other subfields, the set up discharge can be generated with a low voltage to improve the contrast due to the luminous output reduction.

Abstract: A plasma display panel apparatus and a method of driving the same are disclosed. Right after power is supplied to a panel, driving waveforms are applied such that an address discharge and a sustain discharge cannot occur during at least one or more sub-fields. Accordingly, time for a source capacitor of an energy recovery unit provided in a scan driver and a sustain driver to be charged with a voltage can be secured and a preliminary time for an element of the driving circuit and the discharge cell to be activated can be secured, to thereby prevent damage of the element.

Abstract: A piping structure of an air conditioner causes a looped main piping connected to a compressor of an outdoor unit of the air conditioner to be branched into two or more branch pipings within a predetermined interval of the main piping and cause the branch pipings to be jointed at an arbitrary location. According to the piping structure, it is possible to reduce a vibration by an interference phenomenon, which is generated when either a refrigerant pulsation or a periodic vibration of the compressor is divided and then combined.
