Abstract: A strap adjusting device includes a buckle having two through-holes spaced by a partitioning wall. A pressing member is slideably and rotatably received in each through-hole. The pressing members are movable relative to the buckle to adjust a distance between each pressing member and a pressing edge in each through-hole. At least one resilient strap is mounted to a body of a pair of swimming goggles and includes two ends each of which is wound around one of the pressing members. The strap is pullable to adjust tightness of the strap when the pair of swimming goggles is worn on the head of the user. The pulling force acting on the strap urges each pressing member to move toward one of the pressing edges to tightly clamp the strap and to fix a length of the strap.

Abstract: A chuck includes a driving element, a sleeve movably installed on the driving element and a ring fit in the socket. The driving element includes a socket for receiving a bit, a shank extended from and a shoulder formed between the socket and the shank. The sleeve includes a shoulder formed on an internal side for contact with the shoulder of the driving element for avoiding detachment thereof from the driving element in a direction. The restraint is fit in the socket for avoiding detachment of the sleeve from the driving element in an opposite direction.

Abstract: A pair of swimming goggles includes two lens assemblies and a bridge mounted between the lens assemblies. An inner side of each lens assembly includes a bridge coupling portion having a longitudinal axis at an acute angle with a central vertical axis of the bridge. The bridge includes two legs and an arcuate section interconnected between upper ends of the legs. The bridge defines a space having increasing widths toward lower ends of the legs coupled with the bridge coupling portions. A spacing between a rear side of the lower end of each leg and a vertical axis extending through a rear side of one of the lens assemblies is smaller than a spacing between a rear side of the arcuate section and the vertical axis. The arcuate section has a rear arcuate face. A spacing from the rear arcuate face to the vertical axis decreases downward.

Abstract: An optical lens system for taking image comprises, in order from the object side to the image side: a first lens element with positive refractive power having a convex object-side surface; a second lens element with negative refractive power; a third lens element with positive refractive power having a concave object-side surface and a convex image-side surface; a fourth lens element with positive refractive power; a fifth lens element with refractive power; and an aperture stop located between an object to be photographed and the second lens element. In the optical lens system for taking image, the number of the lens elements with refractive power being limited to five. Such lens arrangements can effectively reduce the volume of the optical lens system, reduce the sensitivity of the optical lens system and obtain higher resolution.

Abstract: A display with a linear driving device comprises a base, a driving device, and a display. In assembly, the driving device is mounted on the base, and then the display is fixed on a mover of the linear motor of the driving device. The user can use remote control or manual touch control to set a predetermined distance that he wants the display to move, once the display receives signal, it will instantly instruct the linear motor of the driving device to move linearly, so that the display will be moved to a predetermined position.

Abstract: An optical lens system for taking image comprises, in order from the object side to the image side: a first lens element with positive refractive power having a convex object-side surface; an aperture stop; a second lens element with negative refractive power; a third lens element having a convex object-side surface; and a fourth lens element with negative refractive power having a concave object-side surface, an image-side surface of the fourth lens element being aspheric and formed with inflection points. A distance from the image-side surface of the fourth lens element to an image plane along an optical axis being BFL, a total track length of the optical lens system for taking image being TTL, and they satisfy the relation: BFL/TTL>0.12. In the optical lens system for taking image, the number of lens elements with refractive power being limited to four.

Abstract: A towel structure is configured with a plurality of energy bodies mounted on the surface of the towel to form a geometrical pattern with creation and artistry. Due to the energy bodies project from the surface, the energy bodies rub against the skin of the user when using to improve the blood circulation. Additional, the energy bodies mix with energy elements to promote the health of the user.

Abstract: A switching mechanism for a multi-function shower head is mounted inside of a shower head body and coordinates with a water pressure relief valve, including a curbing ring, a dividing disk, an under-driving gear set, an impeller, a transferring stand, a drawbar, a blocking and a top cap; with the transferring stand disposed on the top, and an outlet and a diagonal outlet at bottom of the shower head body; the top cap possesses a joint port; the drawbar is inserted into the tubing, and a restoring spring is set between said end cover and the outside end of the drawbar; a thimble is placed inside of the drawbar.

Abstract: A current inductive timer socket comprises: a principle relay circuit, a reed relay circuit, a plurality of diodes, a reed relay and a resistance, a counter circuit, a holding circuit, a time switch circuit and amplification circuit. When the electric appliance is in use, a signal of voltage drop produced at both ends of the rated resistance will be amplified by the operational amplifier and then transmitted to the counter circuit and an overload detecting circuit, making the counter circuit start to count automatically, and thus time operation is carried out. Further, when electric appliance is overloaded or in the case of short circuit, the power source can also be cut off automatically.

Abstract: An feeder for an auto mounting device includes a main frame, a blocking mean, an intake assembly, a transmission assembly, an input assembly and a sensor. By the sensor detecting the movement of the auto mounting device and transmitting a signal to activate the transmission assembly, the feeder could be in a normal operation without having an intimate contacting with the auto mounting device. Therefore, the feeder can favorably prevent from tremor and attrition while operating in response to the auto mounting device, conducing to a prompt and regular action of the auto mounting device.

Abstract: The invention provides a hole punch structure. More particularly, one end of an exposed longitudinal handle is moved together with a slide rod in a hole-punching mechanism covered by a casing. Thus, when the other end of the handle is pressed down, the slide rod is also moved transversely, a push rod connected to the slide rod is also moved, and a tool shelf is pressed vertically downward to achieve a hole-punching operation of a punching post. This hole punch structure works according to the principle of lever of the longitudinal handle.

Abstract: A method for forming a laminated synthetic leather includes engaging a textile carrier onto a carrying roll, extruding one or more materials with an extruder machine into a film, and feeding the film downwardly onto a lamination roll to have the film carried on a portion of an outer peripheral portion of the lamination roll and to have the film to be suitably cooled by the lamination roll. The film and the textile carrier are then compressed together with the rolls, to form the laminated synthetic leather, and to prevent the film from penetrating into the textile carrier to a greater extent, and to form a soft or flexible laminated synthetic leather.
