  • Patent number: 7518156
    Abstract: In a non-leaded type semiconductor device, a tab, tab suspension leads, and other leads are exposed to one surface of a seal member. A semiconductor element is positioned within the seal member and fixed to a surface of the tab with an adhesive. The tab is formed larger than the semiconductor element so that outer peripheral edges of the tab are positioned outside outer peripheral edges of the semiconductor element. A groove is formed in the tab surface portion positioned between the area to which the semiconductor element is fixed and wire connection areas to which the wires are connected, the groove being formed so as to surround the semiconductor element fixing area, thereby preventing peeling-off between the tab to which the semiconductor element is fixed and the resin which constitutes the package.

  • Patent number: 7518111
    Abstract: Below 50-nm-diameter extremely narrow electrically-conductive fiber is used instead of the electron beam biprism used in the conventional interference electron microscope method. A phenomenon is utilized where a focus-shifted shadow of this fiber is shifted from a straight line by a distance which is proportional to a differentiation of phase change amount of an electron beam due to a sample with respect to a direction perpendicular to the fiber. The phase change amount is quantified by calibrating this shift amount through its comparison with a shift amount caused by another sample in terms of which the corresponding phase change amount has been quantitatively evaluated in advance. The differentiation amount of the quantified phase change in the electron beam due to the sample is visualized, or eventually, is integrated thereby being transformed into absolute phase change amount to be visualized.

  • Patent number: 7518998
    Abstract: In an IP packet communication apparatus, an operation and maintenance function capable of monitoring a transmission path is provided to a layer used to process a packet, which corresponds to an upper layer of an optical network. As one method for applying the operation and maintenance function to the packet layer, in the case of IP over PPP over WDM, an operation/maintenance frame is defined to a PPP frame so as to realize the operation/maintenance function of a PPP connection. In the case that a plurality of connections are multiplexed on the same transmission path, a maintenance frame is conducted in order to operate/manage these connections by being grouped, so that a fault occurring in the optical network is monitored. As another method for applying the operation and maintenance function to the packet layer, an operation/maintenance frame is defined to an IP packet so as to realize an operation and maintenance function of an IP flow.

  • Patent number: 7513155
    Abstract: Four sensor units (SUA1 to SUA4) are disposed symmetrically about a point, on both top and bottom and left and right centering around one point of a support (15e). Furthermore, four sensor units (SUA1 to SUA4) are designed so that all the components are fully in tuning-fork structure. Drive frames (5, 5) of the sensor units (SUA1, SUA2) disposed adjacent to each other in a first direction (Y) are vibrated in mutually inverted phases, and drive frames of the other sensor units (SUA3, SUA4) disposed adjacent to each other in a second direction (X) are vibrated in mutually inverted phases as well. Moreover, the drive frames of the sensor units (SUA1, SUA2) and the drive frames of the other sensor units (SUA3, SUA4) are operated in synchronization in the state in which phases are shifted by 90 degrees. Whereby, it is possible to reduce or prevent vibration coupling in the driving direction and in the detection direction, and the leakage (loss) of excitation energy and Coriolis force.

  • Patent number: 7514294
    Abstract: The semiconductor device having the structure which laminated the chip in many stages is made thin. A reforming area is formed by irradiating a laser beam, where a condensing point is put together with the inside of the semiconductor substrate of a semiconductor wafer. Then, after applying the binding material of liquid state to the back surface of a semiconductor wafer by a spin coating method, this is dried and a solid-like adhesive layer is formed. Then, a semiconductor wafer is divided into each semiconductor chip by making the above-mentioned reforming area into a division origin. By pasting up this semiconductor chip on the main surface of an other semiconductor chip by the adhesive layer of the back surface, the semiconductor device having the structure for which the semiconductor chip was laminated by many stages is manufactured.
