Abstract: A test pin unit that allows a test-pin replacement at a substantially low cost. The test pin unit has a coil spring, a movable member, a retaining member, and a test pin. The movable member is capable of moving within a predetermined distance along a predetermined reference axis. The coil spring forces the movable member toward the distal end of the predetermined reference axis. The retaining member retains the test pin substantially in parallel to the reference axis in a removable manner and is integrally mounted on the movable member. In addition, the retaining member has a housing part to hold a part of the test pin and at least one screw provided on the periphery of the housing part. The test pin is fixed on the housing part by housing the part of the test pin and then securing the part of the test pin on the housing part by the screw.

Abstract: When a charging lid is manually opened or closed, a rotatable shaft is rotated thereby. At this time, a second rotary member rotates about the rotatable shaft and moves axially along the rotatable shaft. Balls are released from engagement recesses defined in the second rotary member, disengaging a first rotary member from the second rotary member. The charging lid can thus easily manually be opened or closed. When the rotatable shaft is rotated a given angle, a sensor detects the angular displacement of the rotatable shaft and outputs a detected signal. In response to the detected signal, a motor is energized to rotate the rotatable shaft to forcibly open or close the charging lid.

Abstract: An apparatus for displaying the charging of the battery of an electric vehicle has a charging connector mounted on an outer panel of a vehicle body of the electric vehicle, a lid openably mounted on the panel in covering relation to the charging connector and a cavity defined in the outer panel, and a display panel disposed in the cavity for displaying a period of time required until the battery is fully charged and/or a charged capacity of the battery. The driver of the electric vehicle can easily recognize the remaining time required until the battery is fully charged and a percentage of the fully charged capacity of the battery to which the battery is presently charged, from outside of the electric vehicle. The driver is not required to confirm the state of charge of the battery with an indicator on a battery charger or within the passenger's compartment of the electric vehicle, but can easily confirm the state of charge of the battery from outside of the electric vehicle.

Abstract: A displacement detector for enabling a precise detection of a displaced quantity of the core. The displacement detector is provided with a displaceable core, a detecting coil the inductance of which varies in response to a displaced quantity and a reference resistor, wherein a transient response voltage in case of a pulse voltage being applied to the inductance and the reference resistor is detected to enable detection of the absolute value of the inductance and thereby the change in the inductance which corresponds to the displaced quantity is detected independently of the peak value or the frequency of the pulse voltage. The displacement detector is preferably used in a torque sensor for an electric powered steering system, wherein the core of the displacement detector is formed of nonmagnetic metal material, the structure is simple, and a sensitive detection of a displaced quantity of the steering torque is possible.
