Caprazene and caprazol could be synthesized by hydrolysis of a caprazamycin. There could be synthesized a caprazene-1′″-amide derivative of the formula (II) and a caprazene-1′″-ester derivative of the formula (III) from caprazene. Further, there could be synthesized a caprazol-1′″-amide derivative of the formula (V) and a caprazol-1′″-amide-3′″-ester derivative and a caprazol-3′″-ester derivative, etc. from caprazol. Furthermore, an imidazolidinone derivative could be synthesized from the ring-opened product of the 1,4-diazepinone ring of caprazol. The novel caprazene derivative, novel caprazol derivative and novel imidazolidinone derivative now synthesized exhibit excellent antibacterial activities against a variety of bacteria, including acid-fast bacteria.

The present invention provides a backlight of a liquid crystal display device having an inclination surface on a light guide plate and preventing a breakage of a liquid crystal panel, wherein light which leaks from the inclination surface is made to return to the light guide plate and the adhesiveness of the light guide plate and a flexible printed circuit board is increased. In a liquid crystal display device having a backlight which radiates light to a liquid crystal panel, LEDs are formed on a light guide plate formed on the backlight as light emitting elements. Between the plurality of light emitting elements, a projecting portion of the light guide plate is formed, and a reflection member is formed on an adhesive sheet which adheres a projection member and a flexible printed circuit board to each other. By arranging the reflective member and the cushion member close to an inclination surface, light from the inclination surface is made to return to a light guide plate side, and an external force from the outside can be alleviated by a cushion member.

A grounding wire is formed by bending a conductive wire. The grounding wire includes a winding portion formed on a horizontal portion so as to be smaller in diameter than a cylindrical portion of a jack, a horizontal proximal portion in parallel to a circuit board, and a connection end bent from an end of the horizontal proximal portion and connected to a ground pattern. The winding portion of the grounding wire is expanded and outwardly engaged to the cylindrical portion of the jack, and elastically and closely attached to the cylindrical portion of the jack by an elastic restoring force of the winding portion. The connection end is then inserted into a hole formed in the circuit board and soldered onto the ground pattern of the circuit board. Static electricity, with which the jack is charged, is discharged from the grounding wire to the ground pattern.

A power device for an automotive vehicle includes an interlock switch 1, a crash sensor 2 for detecting an impact of an automotive vehicle, an interlock relay 3 controlled and turned ON and OFF by the interlock switch 1, and a contactor 4 for interrupting an output circuit 11 when the interlock relay 3 is turned OFF. In the power device, when the interrupting signal is outputted from the crash sensor 2, or when the interlock switch 1 is turned OFF from ON, the contactors 4 are turned OFF to interrupt the output circuit 11. Further, the power device has a switching element 6 connected to exciting coils 4a of the contactors 4 in series and is turned ON and OFF by an interrupting signal from the crash sensor 2. When the crash sensor 2 outputs the interrupting signal, the contactors 4 are turned OFF by the switching elements 6.
