Abstract: A fitting structure for a connector housing can maintain a stable vibration absorbing function. A flange (14) of a connector housing (10) is provided on the periphery with an outer annular retaining wall (15). A rubber sheet (20) is contained in an interior of the connector housing (10). The connector housing (10) is attached to a body (E) of an engine by means of bolts (B) and nuts (N). When fattening bolts (B) and nuts (N), the rubber sheet (20) is compressed. In a conventional fitting structure, the compressed rubber sheet (20) expands laterally to bulge out of the flange (14). Since the outer annular retaining wall (15), however, serves to limit the lateral expansion of the rubber sheet (20) so that the rubber sheet (20) does not bulge out from the flange (14), it is possible to prevent the rubber sheet (20) from changing its physical and/or chemical nature and to effectively maintain its vibration absorbing function.

Abstract: A plastic optical-fiber is provided having a desired length and a desired graded refractive index. To this end, a base polymer is mixed with a non-polymerizable compound having a higher refractive index to obtain a fiber material. This material is then transformed continuously into a fiber in a fiber-preparing unit. A plurality of diffusion tanks are each provided with a solution, each solution having a level of viscosity different from one another. The fiber is then dipped successively into the solutions in the order from a lowest viscosity level to a higher viscosity level. During this process, the non-polymerizable compound and polymerizable compound diffuse inside the fiber and form a graded refractive index distribution. The polymerizable compound is then polymerized and hardened in a drying-and-heating unit. The fiber thus obtained is drawn and coated with a cladding.

Abstract: A power supply unit is provided between a car-carried battery and load units, such as a light control unit. The power supply unit is connected to the load units through a multi-signal line. The power supply unit calculates a consumption current consumed by the load unit using an operating state of the load unit which is received through the multi-signal line from the load control unit associated with the load unit. The power supply unit compares the calculated consumption current with a supplying current supplied form the battery. If the supplying current is excessively large, the power supply unit interrupts the supply of current from the battery to the load unit. Therefore, the power supply device can detect a phenomenon, for example, a rare short of an extremely short shorting time.

Abstract: Full engagement of a male and female connector is prevented if terminal retainers 13,36 are not fully inserted. A detecting protrusion 15 protrudes from the anterior end of a female connector housing 10. When a male retainer 36 is in a temporary stopping position, a female connector contact protrusion 55 is located inside a fitting detecting groove 50 that connects with a hood member 31. As a result, in the case where the retainer 36 is not completely fitted with the connector housing 30, the detecting protrusion 15 and the female connector contact protrusion 55 make contact, thereby preventing the female and male connectors from being fitted in the correct position. A female retainer 13 can engage the hood of a male connector housing in the usual way.
