A semiconductor substrate (1) includes a plurality of semiconductor elements (2) in which functional elements are constructed and which is formed in a grid pattern, wherein continuous linear grooves (3) are formed on longitudinal and lateral separating lines (4) that individually separate the plurality of semiconductor elements (2) with the exception of intersections of the separating lines (4) and portions corresponding to corners of each semiconductor element (2).

A light emitting device has: a light emitting element; a lead that is electrically connected to the light emitting element at its one end and serves as a terminal to supply a power source to the light emitting element; a metal base that the light emitting element is mounted thereon and radiates heat of the light emitting element; and a sealing member that is of transparent resin or glass and covers the light emitting element. The lead is secured to the metal base by a heat-resisting insulating member with a thermal expansion coefficient nearly equal to that of the metal base.

An innovative bone anchor and methods for securing connective tissue, such as tendons, to bone are disclosed which permit a suture attachment which lies entirely beneath the cortical bone surface, and wherein the suturing material between the connective tissue and the bone anchor is oriented in a direction generally transverse to the longitudinal axis of the bone anchor, so that axial pull-out forces exerted on the bone anchor are minimized. The suture attachment to the bone anchor involves the looping of a substantial length of suturing material around a shaft of the anchor, thereby avoiding an eyelet connection which requires a knot and which concentrates stress on a very small portion of the suturing material. Thus, failure rates are greatly decreased over conventional techniques, and the inventive procedures are significantly easier to perform than conventional techniques.

A method of manufacturing an electro-optical device having a curved display surface with high reliability is provided. A liquid crystal panel 100 comprising a TFT array substrate 10 and a counter substrate 20, each composed of a glass substrate or a quartz substrate, is thinned down to, for example, a thickness of 25 μm by a polishing process or an etching process. Subsequently, a first polarizing plate 140, first spacers 260, the liquid crystal panel 100, second spacers 270, and a second polarizing plate 150 are superposed on a base 210 having a curved surface 220 in this order, and then the outer circumference of the second polarizing plate 150 is pressed against the base 210 while curving the second polarizing plate 150 along the curved surface 220 of the base 210. Then, in order to maintain such a curved state, the second polarizing plate 150 is fixed to the base 210 by a double-faced tape 280.

An electrode terminal 42 is connected to a current collector part 12 of electrodes through a deformation restricting member 3. Between laminate seals 2 and 2, a space 15 is formed above and below the current collector part 12. The deformation restricting member 3 is placed close to the inner wall peripheral portion of an outer package including sealing parts 23, thereby forming a deformation-restricting part 22 to restrict the inward deformation of the laminated films 2. In a section extending from the inside end of the deformation restricting member 3 to a battery element 1, the laminated films 2 face the space 15 to allow the deformation of the laminated films 2 in response to the change of internal pressure. At the decrease of internal pressure, the contraction of the laminated films 2 can be localized in the deformation-allowing part 21, thereby reducing the bending stress on an end portion of the sealing parts 23. Thus, the laminate type secondary battery and the battery pack thereof can be provided with the effect that the concentration of stress on the bonded part of the laminated films can be suppressed even when the expansion and contraction of the laminated films are repeated in response to the change of internal pressure of the laminated films bonded to hermetically accommodate the battery element.

A hinge includes a link with two lateral sides, and an assembly comprising a pair of side plates. Protruding from each lateral side of the link is a pair of parallel pins, and each side plate includes a pair of non-parallel guide slots. The assembly and the link are positioned such that each pin slidably engages one of the guide slots and the pins can simultaneously slide in their respective guide slots. Since the guide slots are non-parallel, when one pin is forced to slide in one direction, the other pin of the pair is forced to slide in a different direction, causing the assembly to both turn and translate with respect to the link.

The present invention prevents, when a COF which is connected with an external circuit is bent in a flat display device, the disconnection of lines on the COF. At a position where a line of the COF is connected to terminal portions of a TFT, and the line having a large width is branched into lines having a small width T1 to T3 or T4 to T6. By displacing line branching positions from each other as indicated by an arrow A and an arrow B, when the COF is bent or deformed, stress applied to the line branching positions can be dispersed thus preventing the disconnection of lines.

A utility trailer structural panel (10) of the skin-stiffener type has a skin (15) supported by uniformly spaced stiffeners or roof bows (39). Stiffeners or roof bows (39) are secured to panel skin (15) and extend outwardly from the associated panel skin (15). Each stiffener (39) has central flange (35) from which extend webs (36, 37) to mounting flanges (41, 42). Mounting flanges (41, 42) have free edges and respective beads or curls (44, 46) formed thereon for stabilizing of flanges (41, 42) to improve load transfer at the interface between the roof bows (39) and the skin (15).

A metal bonded drilling and boring tool which can prevent the separation of abrasive grains during drilling and boring to maintain a stable working performance for a long period of time without the need for tool exchange. The tool includes a rod-shaped body having a substantially semispherical front end portion and numerous abrasive grains bonded to an outer circumferential surface of the rod-shaped body at the front end portion and at a portion having a given length from the front end portion by a bond member formed primarily of copper alloy. The bond member contains a material selected from the group consisting of Ti, Al, and a mixture thereof. The copper alloy is selected from the group consisting of bronze containing 10 to 33 wt % of Sn, brass containing 5 to 20 wt % of Zn, and aluminum bronze containing 5 to 20 wt % of Al.
