Abstract: The present disclosure provides a multifunctional climbing operation platform and an operation method thereof. The multifunctional climbing operation platform includes a main machine, clamping devices, a bolt retightening device, and an auxiliary sleeve replacement box, wherein the clamping devices each include: a fixed seat; and a pair of claw bars swingably arranged on the fixed seat and each including a rear bar body and a front bar body hinged together, wherein when the pair of claw bars are opened, an inner angle between the rear bar body and the front bar body is greater than 180°, the main machine and the clamping devices can climb along an object to be climbed, the bolt retightening device can replace different sleeves from the auxiliary sleeve replacement box, and can screw a bolt on the object. The present disclosure has the advantages of a large avoidance range and diverse functions.

Abstract: An X16 nonvolatile memory has 16 input/output (I/O) ports, identified as I/O ports [15:0], and adopts a conversion method, which allows the memory to operate in an X16 mode or in an X8 mode. The method includes receiving a first user command that is sent by an upper computer and belongs to a user mode; determining a disabling command for a module path of the high-bit I/O ports [15:8] according to the first user command; and executing the disabling command and disabling the module path for controlling the high-bit I/O ports [15:8] of the memory so as to operate in an X8 mode.

Abstract: Provided are a mode conversion method and a mode conversion apparatus for a nonvolatile memory. The method includes: receiving a first user command that is sent by an upper computer and belongs to a user mode, where the first user command includes an invoking path disabling instruction; sending an enable signal according to the invoking path disabling instruction; and disabling the module path for controlling the high-bit I/O ports [15:8] in the X16 nonvolatile memory according to the enable signal. After the module path for controlling the high-bit I/O ports [15:8] in the nonvolatile memory is disabled, data transmission and reception of the nonvolatile memory are implemented through the low-bit I/O ports [7:0], and the X16 nonvolatile memory is converted into an X8 mode.

Abstract: A continuously variable transmission has: an input shaft, an output shaft, a toroidal type continuously variable transmission, and a planetary gear mechanism including a sun gear, a ring gear and a planetary gear. The power transmitted to first and second power transmission systems is made to converge to two gears of the planetary gear mechanism, and a remaining gear is coupled with the output shaft. A mode changeover device effects a changeover between, during forward movement, a first mode for a low speed side, which utilizes the first power transmission system and a second mode for a high speed side, which utilizes the first and second power transmission systems. Such changeover is effected by the operation of connecting and disconnecting a first mode clutch and a second mode clutch. The operation of effecting the changeover between the first mode and the second mode is effected in 0.2 to 1 second.

Abstract: A hydraulic type pressing device secures the contact pressure between the peripheral surfaces of respective power rollers and the inner surfaces of respective input side disks and respective output side disks. When a torque to be transmitted changes abruptly, the pressing force of the pressing device is set to a value corresponding to the maximum torque to be transmitted by a toroidal type continuously variable transmission. According to this configuration, the variation of the transmission ratio based on the variation of the elastic deformation values at the respective portions is suppressed to prevent the uncomfortable feeling of a driver.
