According to the chip-on-film structure, binding yield can be increased, and manufacturing cost can be reduced. The invention further provides a liquid crystal panel provided with the chip-on-film structure.

The invention discloses an automobile fuel tank which is low in cost. An upper tank body and a lower tank body are connected firmly and stably. The occupied vehicle interior space is small after a fuel pump and a turning-over valve are installed. The fuel tank comprises the upper tank body and the lower tank body arranged on the lower side of the upper tank body. The upper tank body and the lower tank body are made of metal materials respectively. An upper tank-closing ring edge is arranged on the portion, along the edge of the lower side, of the upper tank body. A lower tank-closing ring edge is arranged on the portion, along the edge of the upper side, of the upper tank body. The upper tank-closing ring edge and the lower tank-closing ring edge are matched and welded together in a rolling mode. The upper tank body is a concave casing with the front end and the rear end being protruding faces and the middle portion being a sunken face. The sunken face of the upper tank body is provided with a fuel pump installing flange and a turning-over valve installing flange. The upper tank body is further provided with an oil filling pipe and a ventilation pipe. The cost of the fuel tank is far smaller than that of a plastic fuel tank. The upper tank body and the lower tank body are connected firmly and stably, and influence of vibration is small; due to the sunken face, the tail portion of the installed fuel pump and the tail portion of the turning-over valve are prevented from protruding or protruding excessively.

Provided is a chip-type semiconductor ceramic electronic component having a ceramic body composed of a semiconductor ceramic, first external electrodes formed on the both end surfaces of the ceramic body, and second external electrodes extending to cover the surfaces of the first external electrodes and a part of a side surface of the ceramic body. The electronic component has a small resistance value variance and a small thermal shock resistance change, and in the electronic component, excellent substrate mounting is performed. When a curvature radius of a corner section of the ceramic body is expressed by R([mu]m), the maximum thickness of a layer brought into contact with the ceramic body, among the first external electrode layers, from an end surface of the ceramic body is expressed by y ([mu]m), and the minimum thickness of a layer brought into contact with the side surfaces of the ceramic body, among the second external electrodes, from the apex of the corner section of the ceramic body is expressed by x ([mu]m), an inequality of 20<=R<=50 is satisfied, and when 0.5<=x<=1.1, an inequality of -0.4x+0.6<=y<=0.4 is satisfied, and when 1.1<=x<=9.0, an inequality of -0.0076x+0.16836<=y<=0.4 is satisfied.

A manufacturing method for a wiring circuit board includes the steps of: forming a board on a surface of a metal layer directly or indirectly through an etching barrier layer; forming an insulating film on the surface of the metal layer; polishing the insulating film to an extent to which a top face of the bump is exposed; and forming a solder ball on the top face of the bump.

The present invention relates to a metal-sealing material-feedthrough for igniters of airbags or belt tensioning devices, especially glass-metal-feedthrough, including at least one metal pin which is located in a feedthrough opening in the base body in a sealing material, wherein the base body has a front side and a back side. Structure is provided between the front and the back side in order to avoid a relative movement of sealing material in the direction toward the back relative to the inside circumference of the feedthrough opening. At least the feedthrough opening is punched out of the base body. The base body is configured so that the ratio of thickness (D) of the base body to the maximum dimension of the feedthrough opening vertical to the axis direction of the feedthrough opening is in the range of between and including 0.9 to 1.6.

A semiconductor package that includes a semiconductor device and a lead frame having a first lead frame portion and a second lead frame portion, each lead frame portion including a plurality of fingers and a lead pad, each finger being electrically connected to a respective electrode of the semiconductor device.

The invention belongs to the technical field of accessories for assembling profiles, and particularly relates to a compound angle code for corner combinations of the profiles. The compound angle code for the corner combinations of the profiles comprises a first angle code body and a second angle code body which are symmetrically arranged, wherein a first diversion groove which extends along first connection arms and second connection arms is formed in the inner side face of a corner, a first gel injection groove is formed in the outer side face of an adjacent portion of each two adjacent first connection arms, a second gel injection groove is formed in the outer side face of an adjacent portion of each two adjacent second connection arms, a second diversion groove is formed in the outer side face of the corner, a third diversion groove is formed in a corner on an adjacent face of the first angle code body and the second angle code body, the third diversion groove is respectively communicated with the first diversion groove, the first gel injection grooves, the second gel injection grooves and the second diversion groove, and forth diversion grooves respectively communicated with the first diversion groove and the second diversion groove are formed in a corner on a side face of the first angle code body, far away from the adjacent face, and a corner on a side face of the second angle code body, far away from the adjacent face. When used, the compound angle code for the corner combinations of the profiles can improve connection strength of the profiles after the corner combinations, simultaneously can improve flatness of corner combination portions of the profiles, and prevents water from leaking through the corner combination portions of the profiles.

A vehicle body front part structure of a vehicle capable of suppressing the upward deformation of side members and pitching in collision by securely transmitting an input in the collision from the side members to an apron member. Rigid members (20) are fixedly installed across the front end part (8c) of the apron member (8) and the side members (2), and the forward parts of the rigid members (20) are tilted diagonally downward so as to form a roughly linear shape from the apron member (8) toward the side members (2) as viewed from the side of the vehicle to distributedly transmit the input into the side members in the collision of the vehicle to the apron member (8) through the rigid members (20) and to suppress the upward deformation of the side members (2) by the rigid member (20).
