摘要:
An electricity-generating system using solar heat energy comprises: a heat storage tank, a pair of heat-sensitizing units with valves, a steam turbine, a solar collecting system comprising a fixed body in the form of a mesh net having mesh openings, a condenser lens coupled to each of the mesh openings of the fixed body, a condenser unit installed at the bottom portion of the fixed body, which includes a collector lens that increases the concentration of energy focused through the condenser lens and transfers heat to the bottom of the body thereof; a heat storage tank combined with the bottom portion of the fixed body, which heats and stores the heat storage medium by heat energy transferred through the collector lens; a circulation conduit which has an upper plate-shaped coiled tube and a lower coiled circulation tube, which is stacked and contained in the heat storage tank.

Disclosed is an electricity-generating system using solar heat energy. The electricity-generating system concentrates solar heat during the daylight hours through a condenser lens at a collector lens, heats a heat storage medium and steam in a latent heat state through the collector lens so as to produce a sensible heat state, drives a generator using the discharge of steam pressure, and in the remaining time, heats the latent heat steam in a heat storage tank in which the heat storage medium is contained so as to drive the generator and generate electricity.

A knob assembly is utilized for selecting a desired function of electronic appliances. The knob assembly includes a front panel having a circular mounting hole at front thereof, a knob freely moved to a voluntary direction, and a front circuit board having tact switches disposed to be pressed by an operation of the knob. The front panel has a tension holder backwardly projected around the mounting hole. The holder consists of a first group of tension ribs vertically and horizontally located and a second group of tension ribs located between the first group of tension ribs, the first group of tension ribs being provided with a groove, respectively. The knob has a knob handle disclosed from the front panel, a rotational sphere inserted into the tension holder, and a contacting member, the rotational sphere being provided with projections on a periphery surface which are coupled with each groove of the first group of tension ribs. The knob is restored by a restoring fot group of tension ribs. The knob is restored by a restoring force of the tension holder to a standard position which allows the projections of the rotational sphere to be always coupled with each groove of the first group of tension ribs.

A package substrate may include an insulating substrate, a dummy pad, a signal pad and a plug. The dummy pad may be formed on an upper surface of the insulating substrate. The signal pad may be formed on the upper surface of the insulating substrate. The signal pad may have an upper surface protruded from an upper surface of the dummy pad. The plug may be vertically formed in the insulating substrate. The plug may have an upper end exposed through the upper surface of the insulating substrate and connected with the signal pad and the dummy pad, and a lower end exposed through a lower surface of the insulating substrate. Thus, a signal bump may accurately make contact with the protruded upper surface of the signal pad.

摘要:
Single nucleotide polymorphisms (SNP) for predicting recurrence of hepatocellular carcinoma after curative surgical resection are provided. The SNPs have a significant correlation with higher risk of hepatocellular carcinoma recurrence after curative surgical resection. Therefore, the SNPs can be used in developing micro-arrays or test kits for predicting recurrence of hepatocellular carcinoma, and in screening drugs to prevent recurrence of hepatocellular carcinoma after curative surgical resection.

Single nucleotide polymorphisms (SNP) for predicting prognosis of hepatocellular carcinoma after curative surgical resection are provided. The SNPs have a significant correlation with an over-expression of MTA1 which is useful prognostic factor for prediction of prognosis or poor survival after curative surgical resection of hepatocellular carcinoma. Therefore, the SNPs can be used in developing micro-arrays or test kits for prediction of the prognosis of hepatocellular carcinoma, and in screening drugs to improve poor prognosis of hepatocellular carcinoma after curative surgical resection.
