A side edge of the rear plate is nearer to a middle of the upper cover than a side edge of the main body. The rocking portion is disposed between the side edges so that the rocking portion may be rotated with respect to the side edge of the rear plate without exceeding the side edge of the main body.

Abstract: A pair of hairdressing scissors and a positioning device thereof, the pair of hairdressing scissors having a connecting structure formed with a recess, a protrusion and a through hole. A positioning device is disposed in the through hole and includes a retaining member, an elastic member and a fixing member. When coupling a plurality of pairs of hairdressing scissors together, the protrusion of a pair of hairdressing scissors is engaged in the recess of another pair of hairdressing scissors. The protrusion moves toward and presses the retaining member, so that the retaining member will overcome the elastic force of the elastic member and retract into the through hole.

Abstract: A card-in/out device for an electrical connector having a base composed of a bottom seat and an upper cover covering over the bottom seat. The device includes a sliding slot structure, a pushing piece and an elastic member. The sliding slot structure disposed in the base has a circulation path formed with a concave first positioning point and an initial second positioning point, and a bottom surface formed with one-way stoppers such that a one-way circulation from the second positioning point to the first positioning point and then the second positioning point is formed. The pushing piece engaged with an inner surface of the upper cover may slide back and forth, and has a push portion to be pushed by an inserted electrical element, and a guiding rod fit into the sliding slot structure. The elastic member provides a force for moving the pushing piece back to an original position.

Abstract: A balance plate intelligent game apparatus, structured to include a lower tier balance plate having a circular arc-shaped bottom portion and a transparent upper tier ball disk combined with a transparent top cover. A ball is disposed interior of the game apparatus so that when a young child treads on the balance plate with both feet and swings his body left and right, the ball is caused to roll into a helical groove of the upper tier ball disk from a helical groove of the lower tier balance plate, the ball then falls into a hole located center of the helical groove of the ball disk and drops into the helical groove of the lower tier balance plate, thereby enabling the ball to continuously roll between the upper and lower tiers.

Abstract: An image sensor module includes a flexible printed circuit board having an upper surface, which is formed with electric circuits and a lower surface. A passive component is arranged on the upper surface of the circuit board. A substrate has a first surface, a second surface and a penetrated hole. The second surface of the substrate is mounted on the upper surface of the circuit board so that the passive component is located within the penetrated hole. A chip is mounted on the first surface of the substrate, and is located onto the penetrated hole. Wires are electrically connected to the chip and the substrate. A lens holder is mounted on the first surface of the substrate and formed with an internal thread. A lens barrel is formed with an external thread screwed on the internal thread and is formed with an opening, an aspheric lens and an infrared filter.

Abstract: A waterbed includes a bed frame, a water mattress mounted on the bed frame, and a flapping device. The flapping device includes two longitudinal shafts rotatably supported by the bed frame and a plurality of flapping members securely mounted on each longitudinal shaft. The flapping members flap the water mattress when the longitudinal shafts turn, thereby creating water waves inside the water mattress. The user's body s can be massaged to obtain effects of exercise, fats removal, and weight losing.

Abstract: A pair of hairdressing scissors, wherein a connecting block is mounted in the hairdressing scissor, on a first wall surface of the connecting block is protrusively formed a rib portion having a retaining ear thereof, and on a second wall surface of the connecting block is defined with a perforation thereof for engaging with the retaining ear, and an elastic member is mounted in the connecting block. Therefore, when the retaining ear of one pair of hairdressing scissors is engaged in the perforation of another pair of hairdressing scissors, the elastic member presses against the retaining ear, in this way, the pairs of hairdressing scissors can be coupled and positioned relative to one another firmly.

Abstract: A combination and padlock includes a housing including a front window, a dial assembly, a cylinder having a keyhole, a rotatable member secured to cylinder and having a spiral groove, a sleeve including fingers moveably retained in the groove, an indicator slidably mounted on the sleeve and including a first state surface having a color aligned with the window in a locked position, and a second state surface having a different color, and a shackle. Inserting a key into the keyhole to clockwise turn the cylinder and the rotatable member will move the sleeve downward by moving the fingers along the groove in one direction, and unlock the lock with the second state surface moved to align with the window for visually informing that the lock has been opened by the key. Alternatively, counterclockwise turning the inserted key will lock the lock and reset the indicator.

Abstract: A golf club head comprises a body defined with a hollow part thereof, an annular groove is defined in a front side of the hollow part, and an annular space is formed between the annular groove and the body. And a hitting panel, in a periphery of a rear side of the hitting panel is disposed an annular wall, and the hitting panel and the annular wall are retained in the annular groove of the body respectively. Therefore, the hitting force is blocked by the annular space, and will not transmit to the body, thus decreasing the waste of the hitting force.

Abstract: A method of adjusting exposure error for multiple products is described. First, one Photo Feed Back System (PFBS) suited to host-product or miscellaneous product is chosen. Different standard points and compensation difference for host-product or miscellaneous product are provided. Then, the PFBS parameter is calculated as an exposure adjustment value. The standard point and compensation difference for miscellaneous product are dependent on host-product.
