  • Publication number: 20080189996
    Abstract: Disclosed is a method of swiftly identifying by touch or sight (including in low light) different keys in a set. Different keys are tagged with protrusions from their surface, and identifiers for different keys may differ in the total number of protrusions (which can vary in arrangement patterns in accordance with the number of protrusions), the shapes of the protrusions, and/or the color of the protrusions. The protrusions are fluorescent to allow identification in low light or dark. The set of protrusions for each key can be adhered to the key by placing them on one side of a support strip, which is coated with adhesive on the other side.

  • Publication number: 20080105941
    Abstract: The invention provides a sensor-type semiconductor package and fabrication method thereof. The fabrication method includes steps of: attaching a sensor chip to a chip carrier; electrically connecting the sensor chip and a chip carrier via a plurality of bonding wires; mounting a light-permeable body to the sensor chip with an adhesive layer as a partition therebetween, wherein the planar size of the light-permeable body is larger than a predefined planar size of the sensor-type semiconductor package to be formed; forming an encapsulant on the chip carrier for encapsulating the sensor chip and the bonding wires with the upper surface of the light-permeable body being exposed from the encapsulant; and cutting through the light-permeable body, the encapsulant and the chip carrier according to the predefined planar size. Accordingly the contacting area between the cut light-permeable body and the cut encapsulant increased and the bonding therebetween is reinforced.

  • Publication number: 20080105942
    Abstract: A sensor-type semiconductor package and a fabrication method thereof are provided. The fabrication method of the sensor-type semiconductor package includes steps of: providing a wafer having sensor chips; attaching light-permeable bodies to the sensor chips, wherein each light-permeable body has a covering layer and an adhesive layer; singulating the wafer so as to obtain a plurality of separated sensor chips with the light-permeable bodies attached thereon; attaching and electrically connecting the separated sensor chips to a substrate module having substrates, forming an encapsulant encapsulating the sensor chips and the light-permeable bodies; cutting the encapsulant along edges of the light-permeable bodies to a depth at least corresponding the bottom edges of the covering layers; removing the covering layers with the encapsulant mounted thereon to expose the light-permeable bodies; and cutting between the substrates to obtain a plurality of sensor-type semiconductor packages.

  • Publication number: 20080079105
    Abstract: A sensor-type package and a fabrication method thereof are provided. A sensor-type chip is mounted on a substrate and is electrically connected to the substrate via bonding wires. A light-pervious body is attached to the sensor-type chip, and has one surface covered with a covering layer and another surface formed with an adhesive layer. An encapsulant encapsulates the light-pervious body. As an adhesive force between the covering layer and the encapsulant is greater than that between the covering layer and the light-pervious body, the covering layer and a portion of the encapsulant located on the covering layer can be concurrently removed, such that the light-pervious body is exposed and light can pass through the light-pervious body to be captured by the sensor-type chip. The above arrangement eliminates the need of using a dam structure as in the prior art and provides a compact sensor-type package with improved fabrication reliability.

  • Publication number: 20040081649
    Abstract: The invention relates to a composition for treatment of atopic dermatitis comprising a suitable IgE antagonist that does not induce the release of mediators of allergy; for example, anti-IgE antibodies that bind to secreted IgE, membrane IgE on the surface of IgE-producing B cells, but not to IgE bound to the Fc&egr;RI on the surface of basophils or mast cells. Preferably, these antibodies also do not bind to IgE bound to Fc&egr;RII receptors. It is also preferable if these antibodies have human IgG1 or IgG3 constant regions, as well as further human portions, if desired. The composition can be administered systemically or topically.

  • Patent number: 6685930
    Abstract: Disclosed is a method of using bifunctional binding molecules, such as two linked VH-VL single chain binding molecules, to recruit a therapeutic agent to a solid tissue site. The therapeutic agent is administered separately from the binding molecules and following the administration of a remover substance which aids in clearing free binding molecules in the circulation. In the preferred mode of the invention, the binding molecules have one specificity for antigens at the target site and one for the therapeutic agent. The binding molecules are administered and allowed time to approach a maximum concentration in the extravascular space. A remover substance, preferably a liposome conjugated with antibodies which are reactive with an antigenic epitope on the binding molecules, is then administered to remove excess binding molecules from the circulation and the extravascular space.
