The second optical module is configured to receive the first light moving in the second moving direction. The first light reaches the third optical module via the first optical module and the second optical module in sequence. The third optical module includes a first photoelectric converter configured to transform the first light into a first image signal.

Abstract: A linear motion apparatus has a linear track, a slider and two sliding-assistant units for a linear motion apparatus. The sliding-assistant units for a linear motion apparatus is mounted between the track and the slider to enhance ease of movement between the track and the slider, and each sliding-assistant unit has two roller rings to receive rollers. The roller rings are elongated rectangular rings, are selectively mounted oppositely crossly around each other. Each roller ring is designed with reduced components to make manufacturing and assembling the sliding-assistant unit easier. Moreover, the roller ring is designed as one unity so no seam will be formed due to assembling two different pieces, such that ensures contact between the rollers and the roller ring smooth.

Abstract: A rolling element chain is applied to retain and arrange multiple rollers at intervals in a line and has a belt assembly and multiple clamping assemblies. The rollers are cylinders mounted parallelly in the rolling element chain. The belt assembly is resilient and has two parallel bars. The clamping assemblies are formed in pairs between the parallel bars to form multiple roller holes on the belt assembly and each clamping assembly has multiple clamping protrusions. The clamping protrusions of each clamping assembly are formed in a line between the parallel bars and alternately protrude oppositely away from the belt assembly and together hold the roller in the belt assembly. Each clamping protrusion has a roller surface and at least one rib. Each rib is formed on and protrudes from the roller surface, thereby, reduces contact area between the clamping protrusions and the rollers.

Abstract: A rolling element chain has a connecting belt and multiple retaining elements. The connecting belt is extended longitudinally and has multiple receiving holes. The receiving holes are defined at intervals through the connecting belt and have two sides opposite to each other. The retaining elements are mounted in pairs on the belt near the sides of each receiving hole and each retaining element has multiple retaining surfaces adjacent to each other. Each retaining surface has a straight segment and a projecting segment having a projecting edge. The straight segments and the projecting segments of the adjacent retaining surfaces on each retaining element are arranged in an alternative manner. The retaining surfaces on each pair of the retaining elements are opposite and facing to each other.

Abstract: A slider for a linear slide system has a body, a cycling frame, multiple rolling elements and two end plates. The body has a base and two leg portions. The leg portions are formed longitudinally near two sides of the base so that the body has a substantially U-shaped cross section. The cycling frame is mounted around the body and has two cycling passages, two ends and two sockets. The cycling passages are defined respectively around the leg portions. The sockets are formed respectively on the ends of the cycling frame. The rolling elements are rotatably and moveably held in the cycling passages. The end plates are inserted respectively into the sockets of the cycling frame.

Abstract: A lubricant supply unit has a casing and a rear seal. The rear seal is mounted on the casing in fluid-tight matter. The casing has four tapered paths defined through the casing. Multiple porous fillings are fitted into the casing. The porous filling near the rear seal has spike protrusions extended into the tapered paths and in contact with a track shaft. Each spike protrusion of the porous filling is compressed by the respective tapered path so that the density of each spike protrusion becomes greater than density of the rest of the porous filling. Therefore, when the lubricating oil inside the porous filling is flowing out of the porous fillings via the tapered paths, flow velocity and amount of the lubricating oil are slow and stable. The rear seal effectively seals a joint between the cover and the casing.

Abstract: In a method of measuring group delay (Tgd) of a device under test, an analog input signal having a predetermined period (T) is provided to the device under test so as to obtain a delayed output signal from the device under test. A phase difference is detected between first and second digital signals converted from the analog input signal and the delayed output signal, respectively. A current (I) corresponding to the phase difference flows through a circuit having a predetermined resistance (R) so as to result in a potential difference (?V). As such, the group delay (Tgd) of the device under test is determined as a function of the predetermined period (T), the current (I), the predetermined resistance (R), and the potential difference (?V). An apparatus for measuring the group delay (Tgd) of the device under test is also disclosed.

Abstract: The present invention is to provide a slide track structure of a linear platform, wherein the center of gravity of the slide track structure of the linear platform may be lowered. In addition, the outer edge of the upper end of the U-shaped guide track is formed with an inclined face or a smooth arc-shaped face, thereby capable of producing better structural stiffness, saving material, and decreasing weight. Thus, the slide track structure of the linear platform of the present invention can increase the structural stiffness, save material, and decrease the entire weight.

Abstract: A linear guide way structure. The structure utilizes spring strips to combine a sliding body assembly and end caps, instead of using screws or pins. The sliding body assembly and the end caps are combined together with an almost constant resilient force provided by the spring strips whose mechanical strength is greater than that of plastic material. The problem of exfoliation between two physically different materials such a metal and plastic never is avoided. Accordingly, the linear guide way is easy to fabricate, operate, and maintain with low cost.

The measurable guide actuator of the present invention uses a U-shaped guide track to function as the guide mechanism. The driving mechanism uses a screw or a belt. The position measuring member includes a ruler body mounted in the guide mechanism, and a reading head sealed in the sliding table to slide therewith so that the position measuring member can be used to measure the displacement position values.

Abstract: A linear guide way structure comprises a guide rail, a slider, and two end cups. The slider has two ends each defining a ball return hole having a first-end-opening, and a ball groove having a second-end-opening. The adjustable end cup is provided with two ball direction changing paths each having a first-mating-end-opening abutting the first-end-opening of the ball return hole, and a second-mating-end-opening abutting the second-end-opening of the ball groove. The adjustable end cup is provided with a plurality of adjusting slits, and at least one of the adjusting slits has a determined depth so that the adjustable end cup is made flexible, thereby adjusting the distance between the two first-mating-end-openings of each of the two ball direction changing paths of the adjustable end cup, so that the first-mating-end-opening can be exactly engaged with the first-end-opening of the ball return hole.
