Abstract: A pen-type screen cleaner for cleaning a screen includes a tubular shell, a rolled cleaning member and a cleaning solution bottle. The tubular shell is formed from a first semi-tubular shell body which is opposite and pivotally connected to a second semi-tubular shell body, and the tubular shell has two opposite first end and second end on which a first receiving trough and a second receiving trough are disposed respectively. The rolled cleaning member is removablly received in the first receiving trough, and the cleaning solution bottle is removably received in the second receiving trough. Accordingly, the rolled cleaning member and the cleaning solution bottle can be received in both ends of the tubular shell, and thus a pen-type form is formed for providing portable convenience.

Abstract: A cleaning disk for an optical pickup head of an optical disk drive has a disk body with a first surface and a second surface. The disk body uses at least one two-step hole portion to mount at least one brush bundle, wherein the two-step hole includes an embedded fine hole and an expansion hole. The brush bundle has a root portion and an end portion, wherein the root portion is fixed in the embedded fine hole, and the end portion protrudes towards the facing direction of the second surface through the expansion hole. When the brush bundle cleans the optical pickup head, the inner edge of the embedded fine hole on the first surface is used as a pivot point to bend the brush bundle into the expansion hole, thus reducing the resistance and wiping damage on the optical pickup head and the planar shifting of the cleaning disk.

Abstract: A lid spray head for a high pressure gas container is provided. The lid spray head includes an annular surrounding wall having an enclosed space and an opening portion; an L-shaped nozzle disposed in the enclosed space, integrally connected to an inner wall of the annular surrounding wall with a U-shaped elastic arm, and having a connection port and a nozzle port corresponding to each other, wherein the connection port is sleeved on a valve protruding member of the high pressure gas container and the nozzle port protrudes out of the opening portion; and a handle disposed out of the opening portion and integrally disposed at a bottom of the nozzle port of the L-shaped nozzle. When turning the handle, the L-shaped nozzle is integrally turned downwards to contact and press a valve protruding member of the high pressure gas container.

Abstract: A two-in-one screen cleansing device includes a holding body having a first and a second section connected to each other back to back, and the first and the second section defining a first and a second chamber, respectively; a cleansing fluid dispenser removably held in the first chamber; and a cleansing unit removably held in the second chamber. The cleansing fluid dispenser and the cleansing unit are held together as an integral body by the holding body 1 to avoid the risk of getting separated from each other easily to cause inconvenience to a user. The user can use the cleansing fluid contained in the cleansing fluid dispenser without the need of removing the cleansing fluid dispenser from the holding body.

Abstract: An apparatus for cleaning head of pin-contact memory card slot mainly includes a base and a sheeted cleaning element. The base is provided at a front end surface with a recess, and the cleaning element is attached to the base so as to shield the front recess. When the base is plugged in a pin-contact memory card slot just like a memory card, contact pins provided in the head of the memory card slot pierce through the cleaning element attached to the front end of the base to locate in the front recess. The cleaning element is in contact with and thereby wipes clean outer surfaces of the contact pins when the latter pierce through the cleaning element.

Abstract: A method of destroying signals stored on a compact disk includes the step of destroying a Start Lead In (SLD) area on a compact disk to ruin lead-in signals recorded on the SLD, such that all other data stored on the compact disk cannot be read. Undesirable disclosure of the data stored on the compact disk is effectively prevented when the compact disk is discarded after the SLD is destroyed.

Abstract: A device for destroying signals stored on compact disk includes a base, a punching pin, and a push lever. The base has a top stub for engaging with a central hole of a compact disk positioned on the base, a through hole corresponding to a Start Lead In (SLD) area on the compact disk, and an L-shaped arm portion holding a spring mechanism. The punching pin is vertically movably mounted in the spring mechanism and aligned with the SLD area, and the push lever is pivotally connected at an end to one side of the arm portion for pushing against an upper end of the punching pin. When the push lever is pivotally pushed downward, the punching pin is driven downward to punch a hole on the SLD area and ruin lead-in signals recorded thereon, preventing data stored on the compact disk from being read and disclosed.

Abstract: An integrated compact disc cleaning and labeling device mainly includes pivotally connected top and bottom covers, a turning plate rotatably fitted in the top cover, a CD cleaner rotatably mounted to one side of the turning plate, a sleeve barrel vertically slidably received in a barrel portion of the bottom cover, and a return spring mounted between the bottom cover and the sleeve barrel. The bottom cover includes an annular seat surrounding the barrel portion for supporting a label thereon. When a compact disc is removably supported on a flat top of the sleeve barrel with a print side facing downward and the top cover is closed onto the bottom cover, the label is attached to the print side of the compact disc. Meanwhile, the CD cleaner could be rotated to effectively clean a signal side of the compact disc and ensure a firm attachment of the label to the compact disc.

Abstract: An integrated laser disc cleaning and repairing device includes a case consisting of pivotally connected top and bottom covers, a turning plate rotatably fitted in a hole provided on the top cover, and a base plate eccentrically and rotatably connected to a bottom surface of the turning plate with an operating knob having a lower shaft downward extended through pivot holes on the turning and the base plates. The top cover is provided at an inner surface with a circle of radially inward projected teeth and the base plate at a top surface with a circle of radially outward projected teeth adapted to mesh with the teeth on the top cover. By moving the operating knob to rotate the turning plate, the base plate is caused to revolve around a center of the bottom cover while rotating about the lower shaft portion of the operating knob.
