Abstract:
Disclosed are a driving circuit of a plasma display panel (PDP) driving circuit and a driving method thereof, which can simplify the driving circuit and stably secure a sustain discharge waveform. The PDP includes a first electrode applying a ramp-up voltage, a ramp-down voltage, a scan pulse voltage and a sustain discharge voltage; a second electrode applying a ground voltage GND and a level voltage of a second electrode; and a third electrode applying a data voltage for selecting discharge cells in an address period. In the driving method using a driving waveform divided into a reset period, an address period and a sustain period, positive and negative sustain discharge voltages are alternately applied to the first electrode and the ground voltage GND is applied to the second electrode in the sustain period.

A meditation pillow using craniosacral therapy is disclosed. The meditation pillow includes a columna vertebralis supporting part formed in a user's neck direction to support a part of a columna vertebralis located thereon, an occipital region supporting part formed at a rear of the columna vertebralis supporting part to support an occipital region of a head located thereon, and an occipital region acupressure part protrudingly formed along a superior nuchal line between an atlas and an occipital bone to stimulate nerve fibers of the occipital region.
Abstract:
Disclosed is a nylon-based resin composite that has a sufficiently low moisture absorption rate to substantially prevent the occurrence of deformation and can attain both low warpage and improved impact resistance. The nylon-based resin composite comprises about 100 parts by weight of a base resin and about 1 to about 30 parts by weight of an impact modifier wherein the base resin comprises about 20 to about 80% by weight of a modified nylon-based thermoplastic resin containing benzene rings in the main chain and about 20 to about 80% by weight of a flat reinforcing fiber having a cross-sectional aspect ratio of about 1.5 or more.
Abstract:
Disclosed herein is a composition suitable for use in the production of a fuel cell bipolar plate having improved electrical conductivity and mechanical strength. The composition for a fuel cell bipolar plate can include about 100 parts by weight of a basic resin composition including about 10 to about 50 parts by weight of polyphenylene sulfide as a thermoplastic resin and about 50 to 90 parts by weight of a conductive filler and about 0.01 to about 30 parts by weight of a disulfide compound. The composition can improve impregnation of the conductive filler into the thermoplastic resin.
Abstract:
A method for controlling a heating cooking apparatus, in which an operation of a heating unit is appropriately controlled according to presence/absence or kinds of a load applied to a plate. When no load is applied to the plate, the duty cycle of a heat source is reduced, thereby preventing unnecessary operation of the heat source. Accordingly, power consumption is reduced. On the other hand, when a load is applied to the plate, the duty cycle of the heat source is increased. Speedy cooking may be possible with this control method.
Abstract:
A heating body is provided. The heating body includes a tube, a heating member disposed in the tube, and a supporting unit disposed along a length of the tube to maintain a predetermined space between the tube and the heating member.
Abstract:
The present invention provides a prepolymerized olefin polymerization catalyst and olefin polymerization method using the same. More particularly, the present invention provides a prepolymerized catalyst that is encapsulated with macromonomers produced by polymerizing olefin monomers with a vinyl-terminated polysiloxane compound in the presence of a solid titanium catalyst for olefin polymerization having been previously surface treated with silane compounds containing two or more vinyl groups, and a method for producing polyolefin having a high melt strength using the catalyst.
Abstract:
Disclosed are a method of controlling packet service setup and a mobile communication system. The method includes the steps of: transmitting a packet service request message containing a requested QoS to a packet service node by a mobile communication terminal; transmitting to the mobile communication terminal a packet service request response message including an assigned QoS determined in consideration of the requested QoS and network resources contained in the message received by the packet service node; comparing one or more parameter values among parameters contained in the assigned QoS contained in the packet service request response message from a mobile communication network with corresponding one or more parameter values among parameters contained in the QoS requested by the mobile communication terminal; and transmitting a packet service cancel request message if a difference between the parameter values is greater than or equal to a preset value.
