In a projector-type headlight in which a light-emitting face of an LED 1 is placed perpendicular to an optical axis so that light emitted by the LED 1 is projected ahead of a vehicle through a convex lens 2, the light-emitting face is placed upward from the optical axis of the headlight, and a lower edge side 1a of the light-emitting face is formed into a linear shape and is placed on the optical axis, and a reflection face 3a is placed in a plane formed by the optical axis and the linear-shape edge side 1a of the LED 1 to thereby combine direct light emitted by the LED 1 and reflection light reflected on the reflection face 3a, so that an intensity of light emitted in a direction normal to the light-emitting face from the edge side 1a is enhanced.

A sheet transformer includes a first core having central and lateral legs penetrating a coil on a circuit board, a plate-shaped second core positioned on an end of the first core, the cores being assembled into an integral piece and an air gap being formed between the central leg and the second core, and a fixing member for fixing the cores with respect to the coil. The fixing member has holder portions having claw portions for holding the lateral legs of the first core from a side of the second core respectively, a first spring portion extending from a side of the second core toward the circuit board, for bringing inner plane portions of the legs of the first core into contact with the coil, and a second spring portion for pressing positions of the second core which are opposite to the lateral legs.

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 lamp socket has a socket body with a plugging section in which a lamp plug is removably plugged. In the plugging section, there are a central terminal and a side terminal. An insulation seal member provides electrical isolation between the central terminal and the side terminal and is prevented from dislodging when the lamp plug is removed from the socket body by forming a structure from at least one of the central terminal and the insulation seal member which are adapted to fit into one another. Thus, the removal of the insulation seal member when the lamp plug is plugged out of the socket body can be prevented by the central terminal of the socket body and/or the insulation seal member itself. Therefore, there is no need to install an additional component such as a stopper. Thus, the number of components and its manufacturing cost can be reduced compared with a conventional lamp socket. In addition, this avoids problems such as defects in the lamp or the lighting mechanism caused when a lamp is detached from the lamp socket and replaced with new one, and the insulation seal member thereof is missing, displaced, jammed, cracked or the like when a lamp plug with a replacement lamp is re-plugged in the lamp socket.

A computer aided design technique for clock gated logic circuits effective to reduce the electric power consumption is disclosed. The computer aided design for clock gated logic circuits is conducted by extracting, by the use of information about a clock gated logic circuit under the design, a halt condition under which a clocked circuit driven by a clock signal can halt with no clock signal supplied, generating enable signal candidates, from said halt condition, which can be used as enable signals in the clock gated logic circuit, analyzing the clock gated logic circuit in order to obtain information about a delay time of signal transmission and electric power consumption reduction if respective one of enable signal candidates is used as an enable signal of a clock gating circuit inserted in the clock gated logic circuit under the design, storing enable signal candidate information including the result of the analysis conducted by said analysis step in a information store means, selecting an appropriate one of the enable signal candidates which satisfy given restrictions regarding a delay time of signal transmission in the clock gated logic circuit under the design, by the use of said enable signal candidate information; and adding the clock gating circuit activated with the enable signal as selected by said enable signal selection step to the clock gated logic circuit under the design.
