Abstract: A mounting aid for installing curtain rod brackets includes a main body is at two opposite ends with correspondingly arranged marking holes. With the mounting aid, a user can easily utilize the marking holes to put marks on a wall at desired positions for fixing curtain rod brackets, allowing quick execution of subsequent steps of fixing brackets and assembling the curtain rod to complete the installation of a curtain at reduced labor and time cost.

Abstract: A safety mechanism for Roman shade includes a shade assembly having a head rail, a shade cloth connected to the head rail, and connecting members set on the shade cloth; a lifting unit connected to the shade assembly and having pull cords and raising cords connected thereto; a plurality of butt-connecting devices connected to the pull cords and each having two detachably connected upper and lower sleeves; and a plurality of locking members associated with the raising cords and detachably engaged with the connecting members. When a pull cord or a raising cord is subjected to a load excessively larger than a force needed to lift or lower the shade cloth, the upper and lower sleeves of the butt-connecting device on that pull cord will separate from each other and the locking members on that raising cord will disengage from the connecting members, making the Roman shade safer for use.

Abstract: A safety device for roller shade bead chain includes a connecting seat, a rotary disc disposed atop the connecting seat and provided along a circumferential face with a plurality of retaining recesses, an elastic element located between the connecting seat and the rotary disc, and a cover plate assembled to the connecting seat to restrict the rotary disc and the elastic element to the connecting seat. A bead chain for controlling a roller shade can be wound around the rotary disc, and then pulled into a straight state before the connecting seat is fixed to a predetermined position. The bead chain being pulled straight and held in place via the safety device will not swing freely to dangerously entangle with and strangulate a child, and is therefore safer for use.

Abstract: A curtain bead chain fixing device includes a bead chain guide way through which a bead chain as a pull cord for controlling a curtain is extended and thereby becomes connected to the fixing device, and an elastically movable interfering element being normally pushed into the bead chain guide way to interfere with the free movement of the bead chain in and along the bead chain guide way. When the fixing device is adequately mounted to a wall surface according to specified installation procedures, the interfering element is forced out of the bead chain guide way to release the bead chain therefrom. Therefore, a user of the curtain is urged and guided to adequately mount the fixing device to hold the bead chain in place, and undesired accidents caused by a swinging bead chain can be avoided.

Abstract: Contamination due to deposited particulate matter has been greatly reduced in single wafer sputter-etchers by coating the full interior of the sputtering shield with a layer of an arc-sprayed material such as aluminum, said layer being possessed of a high degree of surface roughness. The method for forming the coating of arc-sprayed aluminum is described and data comparing particulate contaminant count and product yield before and after the adoption of the present invention, are presented.

Abstract: The present invention relates to a decorative apparatus with multi-layer of lighting plates, which includes a first plate having a designed shape and being not transparent and a second plate having a reflecting surface. Several bulbs are provided between the two plates. By use of the light of the bulb, the decorative effect is novel and unique while the reflecting light showing the special figure of the first plate.

Abstract: The present invention relates to a patterned frame of a lighting string, which includes several similar patterned frames with different dimensions. Each of the patterned frames can be independently use for connecting with the bulb of the lighting string as a decoration. Every patterned frame can be assembled as a single patterned frame for providing a various decorative display.

Abstract: An improved structure of a rim hoop for positioning is disclosed. An improved structure of a rim hoop for positioning having a drum bell, a drum hoop for positioning a drum head bolts, and rim hoop and lug, characterized in that the lug is an arch-shaped structure including a straight shaft rod and a seat rod at the ends thereof, the lug is positioned at one side of the drum bell, the rim hoop is mounted onto the middle section of the shaft rod by means of an elastic circular pad such that the rim hoop and the lug are directly connected to the external ring surface of the drum bell, facilitating the drum bell to position the drum hoop with bolts fastening onto the lug.

Abstract: This invention relates to a bulb assembly on a soft support. The structure includes a bulb connector, a bulb holder, and a bulb, wherein the bulb connector is provided with an extended connecting plate having several branches with end hook. The connecting plate of the bulb assembly can pass through an opening formed on a soft support, and a joint plate has several separated legs and a pair of inward hooks to engage with the branches of the connecting plate that combines the joint plate with the connecting plate together in secure for fixing the bulb assembly on the soft support, while the soft support with the bulb assembly can be easily folded and stored.

Abstract: The uniformity of material removal, as well as contamination due to deposited particulate matter, has been reduced in single wafer sputter-etchers by providing an improved gas baffle. Said gas baffle presents a smooth surface to the incoming sputtering gas so that it disperses uniformly throughout the sputtering chamber, thereby avoiding local fluctuations in pressure which, in turn, can lead to local differences in material removal rate as well as to particulate contamination of the surface that is being etched. The design of the baffle is described along with a method for attaching it to the inside of the sputtering shield.
