Abstract: The present disclosure describes a system and a method for a ion implantation (IMP) process. The system includes an ion implanter configured to scan an ion beam over a target for a range of angles, a tilting mechanism configured to support and tilt the target, an ion-collecting device configured to collect a distribution and a number of ejected ions from the ion beam scan over the target, and a control unit configured to adjust a tilt angle based on a correction angle determined based on the distribution and number of ejected ions.

Abstract: A smart ventilation fan device includes a fan, a light-emitting module, a sensor set, a wireless module and a control circuit. The fan includes a motor. The sensor set is for sensing environment information. The wireless module is for receiving a command signal from an electronic device and for transmitting the environment information and ventilation fan device information to the electronic device. The control circuit includes a micro-controller which is for generating a control signal according to the command signal received from the wireless module, so as to control the motor of the fan to rotate, and the micro-controller processes the environment information sensed by the sensor set and/or the ventilation fan information. The micro-controller of the control circuit transmits the environment information and/or the ventilation fan information to the electronic device through the wireless module. The invention further includes a smart ventilation fan system.

Abstract: A method for screening of a to-be-analyzed candidate as a skin-whitening agent, includes the steps of: (a) setting a first feature parameter corresponding to a first group of zebrafish that are bred under a predetermined set of breeding conditions; (b) administering the to-be-analyzed candidate to a second group of zebrafish that are bred under the predetermined set of breeding conditions; (c) capturing images of the zebrafish in the second group; (d) determining, from the images captured in step (c), a second feature parameter corresponding to the second group of zebrafish; and (e) concluding that the to-be-analyzed candidate is suitable as a skin-whitening agent if a difference between the first and second feature parameters has statistical significance. A system for implementing the method is also disclosed.

Abstract: The present invention provides a Christmas wreath, which applies a non-circular metal wire to connect bells, wherein additional positioning members are added between the adjacent bell groups for separation. The non-circular inner hole of the positioning member can obtain a refrained position between the positioning member and metal wire, and prevent arbitrary rotation of the positioning member. The outer rim of the positioning member includes at least one included angle, and formed into an inclined guiding surface to coordinate with the end. This enables the positioning member end to insert into the bell ring concave to obtain a refrained position relation between the positioning member and bell, preventing the bell from arbitrarily rotating. The present invention can truly maintain the pattern of connected bells through the mechanism of the positioning member for the bell and metal wire.

Abstract: A hooking device for door decorations includes a bracket which can be hung on a top end of the door. The bracket has a first connecting portion and the first connecting portion connects with a flexible sheet. The flexible sheet has a hook body at an end opposite to the bracket. The bracket can be hung on the door, and flexible sheet can naturally hang at one lateral side of the door due to its gravity, the hook body can hook required decorations. By means of the flexible sheet being foldable, the hook body can be received in an interior of the bracket so that the hooking device can easily be stored and used.

Abstract: A decoration includes a main body. The main body forms an outer edge portion and an inner edge portion. The outer edge portion is formed around a periphery of the inner edge portion. The inner edge portion has at least two disconnected coil cutting lines. The cutting lines equidistantly wrap around to a center of the main body and connect with each other, for the main body separately forming adjacent corresponded first convolution and second convolution by the cutting lines. By means of the convolutions being respectively pulled out toward opposite sides of the outer edge portion along an axial direction for positioning, making the convolutions respectively form conical revolutions at opposite sides of the outer edge portion, achieving tri-dimensional decoration.

Abstract: A decorating structure for hanging Christmas stocking includes a main body suitable of being placed on a platform, the main body has a positioning box, and a decoration is disposed on a top surface of the positioning box. An antiskid pad is disposed on a bottom surface of positioning box, and a flexible sheet is fixed to the positioning box. The flexible sheet is able to naturally hanging and a hook is attached to an end of the flexible sheet which is remote from the positioning box. By means of the application of a flexible sheet, the placement position of the main body can be adjusted according to users' requirement and safety consideration, and meanwhile the decorating structure is of decreased volume, and convenient for storage and transportation.
