Abstract: A process for producing high precision apertures in plastic components comprises the steps of: injection molding the component from a crystalline or semicrystalline thermoplastic material wherein at least one aperture is formed in the component during the molding step; inserting an annealing rod having an oversized diameter with respect to the aperture into the aperture; placing the component, with the annealing rod inserted into the aperture, into an oven at an elevated temperature for a period of time; allowing the component to cool; and withdrawing the annealing rod from the aperture of the component.

Abstract: A simplified power on/off protect circuit is provided to enable logic above a predetermined power supply voltage level and disable the logic below such predetermined voltage level. The circuit comprises a zener diode in combination with a transistor such that the zener controls the voltage level at which the transistor turns on. The transistor enables the logic.
