Abstract: A 5?-reductase inhibitor contains saw palmetto extract and seaberry extract as an active ingredient in a synergistic compounding ratio, wherein the compounding ratio by weight of the saw palmetto extract and the seaberry extract is 3:1˜2. The 5?-reductase inhibitor containing the saw palmetto extract and seaberry extract or just the seaberry extract as a 5?-reductase inhibitor can be administered to the human body in order to inhibit 5?-reductase. The 5?-reductase inhibitor is useful as a prostate enlargement inhibitor, an androgenic alopecia inhibitor, and an acne prevention and amelioration agent. The 5?-reductase inhibitor can be part of a food or drink composition or a cosmetic composition.

Abstract: Load type electrical parts incorporated in auxiliary machine modules 164a to 184a are driven by electrical connectors 160a to 180a having communicating units, control units and load driving units mounted on electronic boards. An electronic door control unit 200a connected to a sub bus connected to the electrical connectors 160a to 180a converts the communication protocol of a control signal of the load type electrical parts received from a LAN in a vehicle serving as a main bus of the vehicle to the communication protocol of the sub bus and transmits the protocol converted control signal to the electrical connectors 160a to 180a. Further, sensors or switches in the auxiliary machine modules 164a to 184a output signals to the control units.

Abstract: A front electronic equipment system includes a load electrical parts provided at a front portion of a vehicle, a front electrical control unit which receives a control signal for controlling the drive of the load electrical parts through a main bus line of the vehicle, and a drive control unit connected to the front electrical control unit through a sub bus line, converting the control signal into a drive signal, and driving the load electrical parts based on the drive signal. The front electrical control unit converts a communication protocol of the control signal from a communication protocol of the main bus line into a communication protocol of the sub bus line, and transmits the converted control signal received through the main bus line to the drive control unit through the sub bus line.

Abstract: An electronic connector connected to a sensor or a switch, and communicating a signal through a common bus includes an I/O unit receiving a signal from the sensor or the switch, a control unit generating a control signal for controlling the driving of a load corresponding to the sensor or the switch according to the signal received from the I/O unit, and a communication unit having a function of decoding the control signal and transmitting the control signal to an equipment connected to the corresponding load through the common bus.
