In a terminal device of a switching device, a terminal screw with a washer is screwed in a terminal strip having a screw hole therein for connecting an external wire. The terminal strips are placed on terminal boards of power supply side and load side formed at both ends of a switching device case. A case cover covers the terminal screw, and a screwdriver is inserted through an insertion hole formed in an upper surface of the case cover to tighten the terminal screw. The terminal device includes a terminal lifter connected to the terminal screw for manually lifting the terminal screw upwardly from the upper surface of the case cover, so that the terminal screw is temporally attached to the case cover at a lifted position after the terminal screw is loosened and detached from the terminal strip with the screwdriver.

The invention discloses a lithium cell safety valve which comprises a sealing ring, a top cover, a PTC (Positive Temperature Coefficient) ring, an anti-explosion membrane and a pore plate, wherein the top cover, the PTC ring, the anti-explosion membrane and the pore plate are sequentially arranged in the sealing ring from top to bottom; a horizontal clip fastening end of the anti-explosion membrane is clipped and fastened above the periphery of the top cover; and the periphery of the top cover is aligned to the outer edge of the PTC ring. The lithium cell safety valve also comprises insulating layers which are arranged at the inner sides of a vertical clip fastening end and the horizontal clip fastening end of the anti-explosion membrane, at the outer side of the edge on the periphery of the top cover and at the outer side of the edge of the PTC ring and clipped and fastened above the periphery of the top cover. In the lithium cell safety valve, the insulating layers are arranged at the outer side of the edge on the periphery of the top cover, at the outer side of the edge of the PTC ring and between the vertical clip fastening end and the horizontal clip fastening end of the anti-explosion membrane, which can prevent the anti-explosion membrane from causing a short circuit on the PTC ring to invalidate the PTC ring and guarantee that the protection function of the PTC ring isnot influenced, thus the lithium cell safety valve can be used for solving the problem of cell leakage quality and has the advantages of high rigidity and convenient assembly.

The invention relates to an electric control gear-shifting controller of a transmission gearbox of a loader. The electric control gear-shifting controller comprises a shell, wherein a circuit unit is arranged in the shell, and a mounting plate is arranged on the shell. The electric control gear-shifting controller is characterized in that the circuit unit comprises a logic control module and a power supply module for providing a direct-current voltage for the logic control module, wherein the logic control module is achieved by a logic circuit and is provided with 8 input ends, each input end corresponds to the output end of a gear-shifting handle, and the logic control module controls a corresponding electromagnetic valve in electric control speed-changing operating valves to enter an on state according to the output of the gear-shifting handle so as to enable corresponding gears of a clutch to combine to realize gear-shifting. The electric control gear-shifting controller of the transmission gearbox of the loader, disclosed by the invention, has the advantages of effectively protecting a complete electric appliance and avoiding electromagnetic interference.

The invention discloses an automobile seat safety belt system with reversible early warning function, and belongs to the technical field of automobile active and passive safety. In order to remind a driver under the conditions of poor driving behaviors such as fatigue driving, illegal operation and the like of the driver and reduce or avoid traffic accidents, the invention designs the automobile seat safety belt system integrating the three functions of reversible early warning, electric pre-tightening and force limiting protection by adopting an electromechanical combination method. The reversible early warning safety belt system mainly comprises a safety belt braid, a safety belt scroll, a driving motor, a centrifugal clutch device, a belt transmission device, a force limiting torsion bar and a motor control circuit. When the automobile runs normally, the reversible early warning safety belt system has the same functions as the traditional passive safety belt. When the driver has poor driving behaviors, the reversible early warning safety belt system receives signals provided by an early warning monitoring system and drives the motor to act, and the driver is reminded through the tensioning force of the tensioned safety belt braid acted on the driver.

The present invention relates to a protective member and a communication terminal device including the same. The protective member (100) having a plate shape is characterized by including: a first base material (10) that is a chemically strengthened glass; and a second base material (20) formed of a material different from a material forming the first base material (10), in which with respect to values of relative permittivity and dielectric loss tangent at a frequency of 10 GHz of the first base material (10) and the second base material (20), the value of at least either one of the relative permittivity and the dielectric loss tangent of the second base material (20) is smaller than the value of the relative permittivity or the dielectric loss tangent of the first base material (10).

The invention provides a heat-resistant adhesive tape having high visibility and a method for the mounting of an image sensor by using the tape as a protection adhesive tape for a solid-state image sensing device. The adhesive tape has an adhesive layer on at least one surface and has a chroma of <=5.0 in terms of b<*> in the L<*>a<*>b<*> color specification system in conformity to JIS Z 8729 after heating at 180 DEG C for 1 hr. The invention further provides an adhesive tape containing an oxidation inhibitor in the adhesive layer in an amount of 0.1-10 wt.% based on the total solid component of the adhesive agent.

The invention provides an endoscope provided with a built-in element protection means capable of protecting a built-in element and locally regulating a bend to protect it easily as well. A light guide fiber bundle 31 as a thin and long flexible built-in element is inserted in the state of being covered with an exterior tube 32 inside a curved part 6 and inside a flexible tube part 5 on the distal end side in an insertion part, and the outer side is covered with a coil member 34 for protection. Since large external force acts on the light guide fiber bundle 31 arranged at a part where the curved part 6 is largely curved, a hard part 38 is formed by adhering the adjacent strands with each other with an adhesive material 36a at the coil member 34 for the protection covering the part, the bend more than needed is regulated, and the built-in element is protected effectively over a long period of time.
