Abstract: A package structure includes a semiconductor device and an adhesive pattern. The adhesive pattern surrounds the semiconductor device, wherein an angle ? is formed between a sidewall of the semiconductor device and a sidewall of the adhesive pattern, 0°<?<90° wherein the adhesive layer has a first opening misaligned with a corner of the semiconductor device closest to the first opening.

Abstract: A magnifying glass for magnifying a portable electronic device (e.g., PDA, or mobile phone) held by the hand is disclosed. In one embodiment the magnifying glass includes a spring-biased clamp adapted to fasten the thumb of either hand and having an extension; a light pivotably releasably secured to the extension; a pivotal member having one end pivotably secured to the extension; a hinge pivotably secured to the other end of the pivotal member; and two lenses each secured to the hinge. The number of lens is one with an elimination of the hinge and is pivotable clockwise or counterclockwise relative to the pivotal member in another embodiment. The single lens is slidable in a further embodiment.

Abstract: A headband comprises a magnifying lens and a detachable assembly comprising a battery compartment received in a well and including a top recessed member, a ridge in the recessed member, a bottom magnet magnetically connected to the well, and a bottom cover; illumination means including a cavity inside a bottom recess; and connection means including a hollow T-shaped post including a top pivot member, a bottom pivot member having a peripheral groove, and two rounded projections at both sides of the top pivot member for pivotably coupling to the cavity; and a hollow, parallelepiped base including an interior peripheral protrusion matingly coupled to the groove, two opposite side pins pivotably coupled to the recessed member, and a bottom toothed member matingly, pivotably coupled to the ridge. The assembly can be detached by inserting a pointed object into a through hole on the well to disengage the magnet from the well.

Abstract: Provided is a device mountable on a head covering. The device comprises a flexible clamp comprising an elongated gap open to its rear, a lower receptacle, two recessed slides at both outer sides of the receptacle, and a toothed-section on a top of the receptacle; a sliding seat of U-section comprising two tabs at both inner sides for retaining a lower portion of the clamp in place after removably sliding the slides therethrough, a latch projected from its bottom to urge against the toothed-section, and a flexible hook having a toothed inner surface; and a lens hingedly coupled to the inner surface of the hook in a gear manner, and a universal joint type light mounted on top of the clamp. The invention enables a desired object to be seen larger and more clear through the pivotal lens (e.g., a magnifying lens) and with light emitted from the light.

Abstract: A head belt of head magnifying glass includes a first and a second head belt set up at both sides of the fixer of magnifying glass. More than one buttoning holes are made on the first head belt vertically. A buttoning seat stretches out from the second head belt. A vacancy forms between said buttoning seat and the second head belt. A through hole is made at the inner and of the buttoning seat and a movable plate is fixed on the buttoning seat. The movable plate is pivoted by its both sides at near the middle part of the lateral sides of buttoning seat. A clamping key is established at the end where the movable plate corresponds with the through hole of buttoning seat and a spring plate is built at the other end. It is easy adjustable by inserting the first bead belt in the above mentioned vacancy and buttoning up the clamping key with the buttoning hole and durableness of head belt is thus achieved.

Abstract: A modified magnifying glass with more than one clamps built on the bottom of the fixer of head magnifying glass for clamping tenons stretching out from the top of magnifying plate. A pivoting seat is set up on the top of said fixer and a revolving bracket set up on the bottom of illuminating body is pivoted at said pivoting seat. It is convenient for the users to replace magnifying plates of different magnification according to needs and magnifying glass can be turned up to vanish from user's sight while it is not in use. Besides, the angle of depression and the angle of elevation of illuminating body can be adjusted by turning the revolving bracket pivoted in the pivoting seat to allow light directly irradiates in use and practical effect are realized.
