In a headlight for in-vehicle use, an LED serving as an optical source is provided in which one edge side of its light-emitting face is formed into a linear portion and placed at a side of an optical axis so that the center of the light-emitting face is displaced from the optical axis. A projection lens is constituted by a radiation-side convex lens and an LED-side convex lens that are arranged in a direction of the optical axis. Between the LED and the projection lens, a light distribution member is placed that is formed using a transparent material and has, on its inner surface, a reflection face for reflecting light emitted by the LED.

Headlight for in-vehicle use

In an LEDhaving a directionality in an emission direction of emitted light, light emitted from a light emitting surface of the LEDis refracted by a semi-cylindrical concave lensto be enlarged in the circumference direction of an optical axis of a headlight; thus, even when the LEDis applied to a headlight that is constituted by optical members that are similar to optical members that are compatible with conventional light sources having no directionality, such as an incandescent lamp, a discharge lamp and the like, it can be used as a light source for headlight that is capable of illuminating the right and left directions ahead of a vehicle with a sufficient brightness.

Light source for headlight and headlight

A lighting device for a headlamp light source includes an connector to be connected to cables for supplying power to the light source, and attached to the bottom of a headlamp case that houses a light source, wherein the output connector is formed such that when the lighting device is attached to the headlamp case, the bottom of a connection opening to which cables of the output connector are connected is disposed at a higher position than a bottom face inside the headlamp case.

A semiconductor integrated circuit includes a function block arranged on a substrate, a first buffering cell arranged adjacent to a first side of the function block, a second buffering cell arranged adjacent to a second side adjacent to the first side of the function block, and signal wiring passing over the function block obliquely relative to the first side and the second side, connecting the first buffering cell and the second buffering cell.

A semiconductor circuit pattern design method includes the following operations. A design pattern is created by placing a plurality of cells in each functional block as a unit of the semiconductor circuit and executing routing among the plurality of placed cells. Mask pattern data based on the design pattern is created. A predictive pattern to be formed on the substrate by the mask pattern data is predicted. A difference amount between the predictive pattern and a target pattern to be formed on the substrate by the mask pattern data is checked. The difference amount is compared with a predetermined allowable variation amount. If the difference amount is larger than the allowable variation amount in the comparison, at least one of placement and routing of the cells in the design pattern corresponding to the mask pattern data used to predict the predictive pattern is corrected.

A through hole that is slightly larger than a size of a rear end of a transformer container is formed in a rear cover constituting a part of an external wall of a starting circuit unit. The transformer container houses therein a transformer and constitutes a transformer portion. The transformer portion is assembled such that a rear end of the transformer container projects from the through hole. This allows the transformer container to constitute a part of the external wall of the starting circuit unit.

A method for generating layout data of a semiconductor integrated circuit includes applying optical proximity correction conditions to cells so as to generate cell patterns, selecting cell patterns to correspond cells, based on layout information of cells along a specified signal propagating path; calculating delay times for the signal propagating path for combinations of cell patterns; selecting a combination of cell patterns, based on lengths of the calculated delay times and the allowable delay time; and generating layout data of the signal propagating path using the selected combination.

A mounting board has a board, retaining members mounted on the upper surface of the board, and a part retained by the retaining members. The part is mounted such that at least a part thereof is arranged below the lower surface of the board, and that the part is electrically connected to the board through the retaining members. Such an arrangement as described above eliminates the need of connecting the discharge gap element to the board by using lead wires, and of mounting it on the upper surface of the board. This lowers the height of the board and admits an elevated part.

A method for distributing clocks to flip-flop circuits which constitute a logic circuit includes obtaining a timing slack of a first minimum delay time with respect to a minimum delay constraint time and a timing slack of a first maximum delay time with respect to a maximum delay constraint time for a clock in an input path to a flip-flop circuit, obtaining a timing slack of a second minimum delay time with respect to a minimum delay constraint time and a timing slack of a second maximum delay time with respect to a maximum delay constraint time for a clock in an output path from all the flip-flop circuits which receive the clocks from a clock terminal directly and obtaining a delay value which maximizes a minimum value of each of the first and second minimum delay time and maximum delay time of timing slacks.

A shielding wire is provided with a first conductor, a shield for sheathing the first conductor through an insulating member, and a second conductor which is in contact with the shield. Therefore, a troublesome step of unknitting the braid of the shield is eliminated, and the work is done at a higher efficiency and the manufacturing cost is reduced.

Providing a high-voltage-side terminal with means for preventing a core inserted into a central hole of a bobbin from getting out of position securely fixes the core to the predetermined position, at the time a transformer which is a part of an ignitor is assembled, during the work proceeds from the inserting step of the core to the next step. Thus, at the time the ignitor-integral type bulb socket is assembled, the core hardly moves out of the predetermined position and there is a less possibility that the core gets out of position. Accordingly, this does not require so high machining accuracy of both members and reduces the cost for machining the product as well as for inspecting the dimension control or the like.

With an automatic layout method, a first line having a first line width is generated in a prescribed direction. A second line having a second line width and extending at an oblique angle with respect to the first line is generated, so that the second line terminates at an end portion of the first line with an overlapped area. One or more VIA patterns are read out of a database according to the shape of the overlapped area. The VIA patterns are placed in the overlapped area, so that one of the VIA patterns is located at the intersection of the center lines of the first and second lines. The VIA pattern is a combination of parallelograms, including squares and rectangles.
