Filed: 1995-06-26
Abstract: PURPOSE: To prevent a malfunction by providing a measuring means, a signal counting means, a waiting means, and a canceling means in a controller. CONSTITUTION: The rain sensor input to a controller 2 is fixed at the H level when a rain sensor 1 is fitted or removed, and it is judged that the rain sensor 1 is not connected when the pulse widths of the prescribed time or longer are continuously measured. When the pulse widths within the prescribed time are again inputted, the pulse widths are measured and counted, and it is recognized that the rain sensor 1 is reconnected. The rain sensor 1 is set to the waiting state to wait the rain sensor input to be stabilized while the pulse width is not measured, the pulse width data of the prescribed time or longer before the H level period after a fixed time elapses are canceled, and the measurement of the normal pulse widths is restarted.  Even if chattering occurs when the rain sensor 1 is reconnected to the controller 2, the rain sensor 1 is temporarily set to the waiting state, and a malfunction caused by the misrecognition of the chattering signal as the measurement signal is prevented.

Abstract: The mounting plate has a track for slidably guiding the hinge bracket in an axial direction and a bore for longitudinally slidably guiding a spring-loaded detent pin, which protrudes from the bore and is held captive therein by at least one stop in the surface defining the bore. The hinge bracket has a sloping surface, which is arranged to force the detent pin into the bore as the hinge bracket is slidably moved onto the mounting plate. The hinge bracket also has a surface which as the hinge bracket is pushed over the detent pin holds the latter in a depressed position until the detent pin snaps into a detent opening of the hinge bracket so that the latter is releasably fixed. A locking mechanism of the type used in retractable ball point pens is provided and is adapted to lock the detent pin in two different (partly extended and fully extended) positions. The pin is adapted to be moved from one of said positions to the other in that the detent pin is depressed into the bore and then released. The free end of the detent pin lies in the path of the sloping surface when the detent pin is in its partly extended position. The pin which has been depressed by the sloping surface is adapted to snap into the detent opening and to be urged in said detent opening by the spring toward its fully extended position.
