Abstract: A standing structure for a shell of an extension cord is provided. Intercalating trenches are disposed on rear edges of a pair of opposite surfaces of the shell of the extension cord. A support frame includes a horizontally-disposed bottom plate and a vertically-disposed support plate connecting the bottom plate and having two intercalating strips intercalated into the intercalating trenches. Thus, the shell of the extension cord can be combined with the support frame to form the standing structure. The planar surface, not combined with the shell of the extension cord, of the support plate thus can face to a user for hiding power outlets and power cables plugged into the power outlets.

Abstract: An adaptive pulse width control power conversion device includes a pulse width adjustable pulse frequency module (PFM) control circuit, a pulse width modulation (PWM) control circuit, a PWM/PFM switching unit, a switching circuit, and a load status detection circuit. When the power conversion device is to be switched from a PWM mode to a PFM mode, pulse width of a series of PFM control signals is sequentially adjusted from a low value to a high value according to a predetermined pulse width increment until an optimum pulse width is determined and thereafter, an output voltage is supplied to a load in the PFM mode, whereby ripple of output voltage in the PFM mode can be improved and improved stability of output of the power conversion device is realized.

Abstract: A novel vehicle which is suitable for transporting and/or temporarily storing objects such as masks or reticles and is effective in eliminating or preventing electrostatic discharges on the masks, reticles or other objects. The vehicle includes a frame for receiving the objects and at least one ESD eliminator provided on the frame for neutralizing electrostatic charges on the objects. Neutralization of the electrostatic charges prevents electrostatic discharges from damaging microelectronic circuits, for example, on the masks, reticles or other objects.

Abstract: A wheel assembly for a trunk-attached carriage includes an integrally formed wheel bracket having a vertical, a side and a bottom plate for mounting onto a lower rear corner of a trunk, a compression spring, a short wheel axle, a locking member, and a wheel. The wheel bracket defines a wheel-space for the wheel to locate therein. The wheel axle transversely extends across behind the vertical plate of the wheel bracket to pass through an axle hole on the wheel, so that the wheel is rotatably mounted on the wheel axle and connected the wheel bracket. An end of the wheel axle close to the side plate of the wheel bracket is connected to a diameter-reduced inner end of the locking member, so that the wheel axle can be turned into a locked position on the wheel bracket by turning a diameter-expanded outer end of the locking member. And, by turning the locking member in a reverse direction, the wheel axle can be removed from the wheel bracket for replacement of any damaged component of the wheel assembly.

Abstract: A handcart is constructed to include two main frames having outward expanded shoulder and lower portions, an extension handle assembly, an upper crossbar, a lower crossbar, a carrier, and two wheel holders. The two main frames have two upper ends fixedly received in side holes formed at the upper crossbar and two lower ends pivotally connected to the carrier. The extension handle assembly includes two outer pipes, two inner pipes, and a top handle. The upper crossbar is provided with a mechanism means to control the extension and collapse of the inner pipes from and into the outer pipes. The lower crossbar may, together with a fastening strap, hold the carrier and luggages loaded on the carrier in place. When the carrier is extended to a horizontal position, the two wheel holders are extended outward at the same time, permitting the handcart to conveniently carry and transport luggages or articles.

The rough boring tool is further composed of a boring tool engaged with the tool hole and provided with a plurality of measuring scales corresponding in location to the reading scales and forming an angle with the base line. The advancement quantity of the boring tool can be easily observed with the naked eye by converging the reading scales of the tool hole of the boring rod and the measuring scales of the boring tool.

Abstract: A luggage cart which mainly includes a handle assembly, a vertical telescopic frame assembly, a movable upper crossbar assembly, a fixed crossbar, a luggage support, a foot-control assembly, a horizontal telescopic frame assembly, and an upper and a lower fixing members for mounting onto a back side of a trunk. The handle assembly has a long pull rod provided therein for controlling the sliding of pipes of the vertical telescopic frame assembly. The movable upper crossbar assembly may be adjusted in height to associate with the upper fixing member and the foot-control assembly may be associated with said lower fixing member. Whereby when the trunk is loaded on the luggage support and the horizontal telescopic frame assembly with the upper and the lower fixing members respectively associated with the upper crossbar assembly and the foot-control assembly, the trunk can be carried with the cart in a laborsaving manner.

Abstract: A stretchable and foldable cart whose handle bar can be stretched, retracted or folded by operation of a pressing rod associated with positioning elastic lugs, pins and stoppers. The loading stage of the car is able to adjust its size according to actual requirements by the operation of push button, positioning stoppers and connecting rods. The front and rear mountings of cart are made of plastics with sufficient engineering strength for reducing the cart weight yet without affecting the cart's functions; facilitating assembly work and reducing production cost.
