摘要:
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:
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.
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.
摘要:
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.
