The rotary table is pivotally mounted on the base and is allowed to be pivoted relative to the base to a horizontal position or to titled positions. The linear actuator is pivotally disposed between the base and the rotary table and located at at least one side of the rotary table in a rotating direction thereof, the linear actuator comprises a motor for controlling extension and extraction of a screw, the motor has one end pivotally connected to the base, and one end of the screw is pivotally connected to the rotary table.

Abstract: A tool moving module for a positioning platform comprises: a base on which is disposed a support table, and on the top of the support table is a pivoting portion; a support frame having a pivoting portion to be pivotally connected with the pivoting portion of the base to enable the support frame to be pivoted about the base to change its tilt angle, on a top of the support frame being formed a carrying surface around a periphery of which being arranged plural clamping members; at least one tilted control assembly disposed between the base and the support frame and located at the same side. After being fixed on the support frame, the positioning platform can be adjusted to a tilted position to substantially reduce its horizontal width, thus facilitating the transportation work.

Abstract: A quick lubricant nipple mechanism with a check device comprises a lubricant nipple which is connected to an extension pipe device having a pipe, an outlet connection, a check valve and an inlet connection. The pipe has one end connected to the outlet connection and the other end connected to one end of the check valve which has the other end connected to the inlet connection. The outlet connection of the extension pipe device is connected to the lubricant nipple, so that the lubricant injection can be carried out quickly and easily and the lubricant gun is easy to align. Hence, with such a device, the lubricant injection can be done by only one person.

Abstract: A preloading and flex resistant support column comprises a support column and preloading member, wherein the support column is provided on one side thereof with a plurality of support portions arranged in straight lines along an axial direction of the support column, the preloading member is provided on one side thereof with a plurality of positioning portions arranged in curve lines along an axial direction of the preloading member. A plurality of screws is screwed through the positioning portions of the preload member into the support portions of the support column. The preloading member is such that its height is larger than its width, so it can produce a moment of inertia which is strong enough to support the support column from deformation.

Abstract: A rotary micro-adjustment mechanism for a synchronous double-drive positioning platform (such as a gantry) is disposed between a beam and support pillars of the synchronous double-drive positioning platform and comprises a positioning pillar and elastic members. The positioning pillar is provided to pivot the beam relative to the respective support pillars to compensate displacement error of the beam and the support pillars. The elastic members are provided to resist the pivotal rotation between the beam and the support pillar by their restoring force, so as to improve the rigidity of the overall mechanism.

Abstract: A plate-carrying apparatus comprises a base, an adjusting rack assembly, a telescopic supporting rack and a bearing seat. The base is connected to the adjusting rack assembly and the telescopic supporting rack, respectively. The adjusting rack assembly is pivotally connected to the bearing seat. A height adjusting mechanism formed by the base and the adjusting rack presses against the bearing seat to fix it, such that the carrying height of the bearing seat can be easily controlled. In addition, the bearing seat is pivotally connected to the adjusting rack assembly, so the bearing seat can be collected by rotating the bearing seat relative to the adjusting rack assembly, so as to reduce the storage space.

Abstract: A CMOS cross-coupled differential voltage controlled oscillator is provided with a pair of oscillator outputs. The oscillator includes a current control unit, a first cross-coupled differential pair, an inductor unit, a capacitor unit, a second cross-coupled differential pair and a voltage controller. The current control unit is coupled between a relatively-high voltage and a relatively-low voltage. The first cross-coupled differential pair, the inductor unit, the capacitor unit and the second cross-coupled differential pair are coupled between the pair of oscillator outputs. According to the present invention, the inductor unit is provided with a midway node. The voltage controller is coupled and powered by the midway node.

Abstract: The present invention relates to a stick fuselage of a model aircraft that also combines an aircraft nose and a main wing brace. The stick fuselage adopts a transverse H-beam as a main body. Two sides of the main body have continuously annular bodies as reinforcement structures. The aircraft nose is connected to a head of the stick fuselage, and has a concave spherical surface and a spherical convex to form a spherical pairing. The middle of the stick fuselage has a fuselage sleeve. Two ends of the fuselage sleeve are connected to a hollow ring respectively to form the main wing brace. The main wing brace uses a hollow double ring as a basic configuration for division assembly and accumulation assembly so as to make a monoplane, a biplane and a triplane.

Abstract: A model stick plane featuring a new assembly of stick fuselage, nose and wing deck support; the nose related to a structure incorporated to the front end of the fuselage to be adapted with a power system and in a shape that varies depending on the type of the power system used; the wing deck support connecting the fuselage; and the wing deck related to a structure essentially provided in relation the hollowed loop structure close to where the center-of-gravity position of the stick fuselage.

Abstract: According to the method of the present invention, first, the code of the program language used to develop a web page is classified and rearranged. Next, the rearranged program code is transferred to another program code with similar syntax. Then, the transferred code is compiled to generate an object file and a web page program file.

Abstract: A main form of stick fuselage of a toy plane has a cruciform cross section. The stick fuselage is formed by plastic material and is integrally formed with a main wing support framing and a tail unit framing. Moreover, a propeller axle bearing, a landing gear framing, a dihedral bracket jointer, a rear rubber hook, and a tail skid may be integrally formed with the main form of stick fuselage.

Abstract: A closure with sashes includes a closure body, an inner sash enclosing around the closure body and including a first upper rail, a first lower rail, a first left stile and a first right stile and an outer sash matchable with the inner sash, including a second upper rail, a second lower rail, a second left stile and a second right stile and adapted to be mounted on a wall of a building wherein there exists a characteristic that the first upper rail is identical to the first lower rail in shape.
