IPC: G02B6/44
Filed: 2000-09-19
Abstract: PROBLEM TO BE SOLVED: To make the shape of the envelope of an optical fiber cable which is the constituent element of an aerial concentric drop cable into the shape with which a cicada cannot oviposit near a coated optical fiber or hardly oviposit. SOLUTION: One coated optical fiber 1 at the center of the cable and two tension members 2 disposed at both sides of and in parallel to the fiber 1 are covered in bloc with the outer sheath 3 with a nearly rectangular cross section so that the fiber 1 and the members 2 are included in the same plane. Notches 4 extended in the longitudinal direction in parallel with the fiber 1 are provided on the surface, parallel to the above plane, of the sheath 3 and just above and just below the sheath 3.

Title: Semiconductor device
Inventor: SATO YUKIHIRO
IPC: H01L23/50
Filed: 2000-09-21
Abstract: PROBLEM TO BE SOLVED: To prevent decrease in heat dissipation of a QFP, in which a tab is exposed from the bottom surface of a resin-sealed body. SOLUTION: In the QFP 37, in which the tab 18 is exposed from the bottom surface of the resin-sealed body 35, a pellet 32 and a step part 21 having a thinner opposite side (top surface side) are formed around the tab 18, a protruded/recessed part 22 is formed to surround the part 21 in the peripheral direction. The bottom surface of the tab 18 is exposed from the bottom surface of the body 35, in a state with the part 21 and 22 being embedded in the inside the body 35. Using such a constitution, even if peeling occurs on the interface between the tab and the resin on the bottom surface of the resin-sealed body in which the tab is exposed, since the peeling can be prevented from advancing into the inside of the resin-sealed body by the step part, humidity from the outside can be prevented from penetrating the adhesion layer and peeling of a adhesion layer due to the so-called 'steam explosion' can be prevented; so that the decrease in heat dissipation, caused by increase in heat resistance of the adhesion layer due to the peeling of the QFP, in which the tab is exposed from the bottom surface of the resin-sealed body, can be forestalled.
