Abstract: The present article holder comprises a dual purpose clip which is designed to attach to an article such as a flashlight, a clip attachment that locks onto the clip, and a clamp for attaching to a fixture or clothing. The clip is provided with a shank portion that may be used to clip onto a shirt pocket or like, much in the manner that a conventional pen with a clip is held to a clothing. The attachment is rotatably connected to the clamp so as to permit the attachment to be positioned relative to the clamp. The attachment permits the clip to be removably attached thereto with a locking feature. The end of the shank is provided with a curved enlarged head which cooperate with slots formed at the opposed longitudinal ends of the attachment. The slots and the head cooperate to releasably lock the clip thereunto.

Abstract: A spring clip closure member for resiliently fastening onto a button type projection, of the type typically used in suspenders, jeans, and other garments. The spring clip includes an inverted U-shaped resilient wire loop having a bight portion for suspension form the garment. A pair of opposing leg portions each terminate in inwardly directed feet with downwardly directed fingers. The fingers are resiliently separable but are normally biased toward each other. An encasement member envelopes the feet portions and includes a closed pocket for receiving and enveloping depending finger portions. The finger portions can laterally move within the closed pocket so as to engage and release the button type projection. Lateral apertures are provided in the encasement member through which the feet portions extend during a closure operation.

Abstract: Electrically isolated active device regions are fabricated in GaAs semi-insulating wafers by the implantation therein of sulphur ions. The implanted wafers are then coated with a passivating oxide and annealed at an elevated temperature of 800.degree. C or greater in order to achieve carrier mobilities in excess of 3000 cm.sup.2 /volt second.
