Abstract:
A substrate for a semiconductor package is provided having first and second core layers defining a cavity having an adhesive member and sized and shaped to receive a semiconductor chip. The semiconductor package further having a connection member formed on a bond finger and connected to a via pattern formed through the first and second core layers. A stack package is also provided having multiple substrates.
Abstract:
Provided is a laryngeal stroboscope using voice signals. The laryngeal stroboscope includes a photography unit for photographing a patient's vocal cords and a light source for illuminating a part to be photographed, a microphone for sensing the patient's voice, a high-pass filter for passing voice signals of 100 Hz or more among voice signals output from the microphone, a low-pass filter for removing signals of harmonic components from the voice signals output from the high-pass filter and passing only a voice signal in a fundamental frequency band, a peak detector for detecting a peak of the voice signal output from the low-pass filter and obtaining a pitch, and a controller for controlling the light source to intermittently emit light in response to a signal output from the peak detector and controlling the photography unit to operate according to whether or not the light is intermittently emitted.
Abstract:
Disclosed are a composition for introducing the osteogenic differentiation of human embryonic stem cells and a method for differentiating human embryonic stem cells into an osteoblastic lineage by inhibiting the mTOR signaling pathway. When cultured in the presence of an inhibitor of the mTOR signaling pathway, human embryonic stem cells are effectively induced to differentiate into an osteoblastic lineage. The osteogenic differentiation of human embryonic stem cells using the method and the composition is useful in examining the development and differentiation mechanism of osteoblasts and the cause of metabolic bone diseases, including osteoporosis. In addition, the method and the composition can be applied to the development of osteogenic differentiation techniques for generating clinically useful, terminally differentiated mature cells or progenitor cells.
Abstract:
A control method of a laundry machine comprising a water supply, washing and rinsing cycle, the control method includes first determination step performed prior to the rinsing cycle and determining a kind of detergent, second determination step performed during a first rinsing course of the rinsing cycle and determining an amount of remained detergent in a rinsing water, and condition determination step of at least one following rinsing course based on the kind and amount of the remained detergent.
Abstract:
Disclosed is a method for manufacturing a semiconductor device substrate. A substrate having no bus line and lead-in line is efficiently manufactured. In a step needing an electroplating process, conductive film is temporarily attached to circuit patterns in order to electrically connect all circuit patterns. A plating is formed in desired regions of the circuit patterns with a predetermined thickness in an electroplating method. The conductive film is completely removed while the substrate is manufactured so that the circuit patterns are electrically independent of one another, and the resulting substrate has no bus line and lead-in line.
Abstract:
A multi-layer printed circuit board includes a core layer having a first circuit patterns formed on the upper and lower surface of a first insulation layer and via-holes in which a conductive layer is formed to electrically connect with the first circuit patterns. Built-up layers are formed on the upper and lower side of the core layer and have second circuit patterns electrically connected with the first circuit pattern by means of a via-holes in which conductive layers are formed to electrically connect the first circuit patterns of the core layer and the second circuit patterns of the upper and/or lower built-up layers. The via-holes in the core layer and the via-holes in the built-up layers are formed from an each side/both sides of the core layer and from the built-up layers toward the core layer, whereby interconnection of the circuit patterns is obtained without using through-holes and permitting shortening of the wiring and higher integration.
