A practical cable made of a high strength fiber composite material is provided, which has high and stable strength, in addition, has even axial tension against bending and thus has a stable shape, and can be wound on a reel without shape deformation, and is hardly buckled when it is inserted into a hole or cylinder. The cable is formed by singly twisting a plurality of high strength fiber composite materials is used as a strand, and a plurality of the strands are twisted together at a twist angle of 2 to 12 degrees in a direction opposite to a twist direction of the strands, so that a double twist structure is made.

In the motor stop control device utilizable for the reel-type gaming machine 1, there are provided the stepping motor 70 having two pairs of excitation phases for rotating the reel 3 on the outer periphery of which a plurality of symbols are formed, the speed reduction mechanism 700 for transmitting rotation of the stepping motor 70 to the rotation shaft of the reel 3 with a predetermined speed reduction ratio and the main CPU 40 for conducting speed reduction treatment to reduce rotation speed of the stepping motor 70 and excitation treatment by 2-phase excitation against the stepping motor 70 when the motor stop command occurs.

The invention provides an aseptic filling valve, which comprises a valve body and a valve rod with a valve plug, and is provided with a lever driving the valve rod to lift; the lateral surface of the valve body is provided with a lever extending-in opening, and the lever extends into the valve body from the lateral surface of the valve body; and the aseptic filling valve is also provided with a flexible diaphragm which is in seal fit with the lever and encloses the valve body on the lever extending-in position. The aseptic filling valve can realize constant aseptic obstruction under the working condition of long-time frequent opening and closing so as to improve the safety of aseptic filling production; moreover, distances to a lever fulcrum are different, and the rotation amplitudes of the lever are different, so that manufacturers have more options to flexibly adopt an aseptic obstruction implementation proposal with economy, high reliability and easy realization according to actualconditions.

Problems encountered in the conventional inspection method and the conventional apparatus adopting the method are solved by the present invention using an electron beam by providing a novel inspection method and an inspection apparatus adopting the novel method which are capable of increasing the speed to scan a specimen such as a semiconductor wafer.The inspection novel method provided by the present invention comprises the steps of: generating an electron beam; converging the generated electron beam on a specimen by using an objective lens; scanning the specimen by using the converged electron beam; continuously moving the specimen during scanning; detecting charged particles emanating from the specimen at a location between the specimen and the objective lens and converting the detected charged particles into an electrical signal; storing picture information conveyed by the electrical signal; comparing a picture with another by using the stored picture information; and detecting a defect of the specimen.

A stabilizer assembly is at least 12′ long and preferably at least 14′ long and is used to drill a straight bore hole in the earth. A central passage through the assembly closely follows a centerline as may be determined by measuring the wall thickness of the tube at a variety of locations in a single plane. At least three stabilizing sections are integral with the tube and include alternating ribs and flutes. Hardbanding on the ribs is ground down to tolerances with a grinding machine or face plate lathe having centers sufficient to receive the 12′ long stabilizer assembly.

A utility vehicle is equipped with a R.O.P.S. enclosing a passenger space, a cargo bed disposed behind the passenger space, and a screen disposed between the passenger space and the cargo bed. The screen is divided into an upper screen and a lower screen.

The invention relates to the technical field of photography and video shooting equipment, particularly to a button mechanism of a tripod and the tripod. The button mechanism of the tripod comprises angle clamping structures and button structures, and further comprises supporting structures, wherein the angle clamping structures are fixedly arranged on a body of the tripod; the button structures comprise buttons rotatably arranged on foot shaft sleeves of the tripod through first shafts; the buttons are provided with combination parts applicable to combination with clamps of the angle clamping structures; the combination parts and the clamps are combined to lock the opening angle of supporting feet of the tripod; when the combination parts and the clamps are combined, the supporting structures are propped against the buttons; and included angles exist between the extension lines of the connecting lines from supporting parts of the supporting structures to the combination parts and the extension lines of the ends, facing the angle clamping structures, of the supporting feet. According to the button mechanism of the tripod and the tripod provided by the invention, supporting stability of the supporting feet of the tripod is strengthened, cost of the angle clamping structures is reduced, product structure is further simplified, and market competitiveness of products is improved.
