Abstract:
An open end ratchet wrench includes a socket member rotatably received in an opened head member and having a number of teeth and having an open notch for selectively aligning with an open slot of the head member, a pawl engaged in the head member and having a toothed end for selectively engaging with the teeth of the socket member and for allowing the socket member to be rotated in one direction by the head member, and a spring biasing member engaged with the pawl and having two end portions extended out of the pawl and engaged with the head member for anchoring the spring biasing member to the head member and for evenly biasing the pawl to engage with the teeth of the socket member.
Abstract:
A drying and freezing method without cooling medium comprises the steps of removing moisture, separating cold air from hot air and mixing the cold air with the hot air. Under the condition of no cooling medium, the above-mentioned steps separate the moisture from the compressed air, separate the cold air from the hot air and mix the cold air with the hot air. The system using the drying and freezing method without cooling medium comprises at least one air dryer having an air-moisture separation chamber for separating air from moisture and at least one separator having a separation chamber for separating cold air from hot air. The separator is connected to a pipeline to mix the cold air with the hot air.
Abstract:
An adjusting structure of laptop includes a main body with a longitudinal portion and a transverse portion. The longitudinal portion has interior room with an opening on the top and the transverse portion is configured to the laptop host and can be turn around the host. At least one track is configured on the inner wall of the longitudinal portion. A movable component configured in the interior room matching the track moves longitudinally along the track and exposes from the opening. The display-panel of the laptop is configured on the exposed end of the movable component.
Abstract:
A contact element of an electrical connector includes an anchoring section having barbs for securing the contact element in a bore defined in a connector and a pin engaging section connected to the anchoring section by a reduced connection section. An elongate projection is formed on the connection section and substantially extends therealong for blocking a wicking path between the anchoring section and the pin engaging section thereby suppressing wicking of solder and/or gold coating through the connection section. The projection may be simply formed by pressing the connection section. The projection may be replaced by an elongate opening.
Abstract:
A socket receiving device includes a base with a plurality of receiving units connected thereto, the receiving units disengagably connected with each other side by side. Each receiving unit has a recess defined therein and a protrusion extends from one of two closed end of each receiving unit. The other closed end of each receiving unit is a plate which is pivotally connected to the base. The plate has a plurality of apertures defined therethrough so that a wire extends through the socket in the recess and the aperture to secure the socket to the device.
Abstract:
A switching power supply capable of reducing secondary-side noise mainly has at least one decoupling device for guiding the secondary-side noise to at least a terminal of an AC power supply. Thus, the secondary-side high-frequency noise can be reduced, and the quality in using the electronic apparatus product, which is electrically connected to the output of the switching AC-to-DC power supply, can be greatly enhanced.
Abstract:
A laptop has a wireless module set in a base or elsewhere and an antenna set in a display or elsewhere. A transmission wire is distributed both in the base and the display to connect the wireless module and the antenna for providing the function of wireless communication.
Abstract:
A portable apparatus with thumb control interface includes a host, a display panel and a thumb control interface. The thumb control interface includes a set of control bottoms located on the host, and the user's one thumb can touch and control the set of control buttons when a user holds the host. The set of control buttons includes a left mouse button; a middle mouse button; and a right mouse button. A pointer, a scroll wheel and a plurality of function keys are also set on the host, and the user's another thumb can touch and control them when the user holds the host.
