In this paper, a new actuator with nanoscale micro-displacement is reported. The actuator not only can achieve a large stroke and nanoscale positioning accuracy, but also has the advantages of compact, low cost, high reliability and a single control system. The drive is controlled by a single power, and it consists of stepper motor, harmonic gear reducer, screw and the guide rail. The stepper motor is controlled by the pulse train and the harmonic gear reducer has high precision and small hysteresis. The precision screw converts the rotary motion of the stepper motor into linear displacement, and the plunger pushes the target in nanoscale motion accuracy through the guide rail finally.

Regenerative cryocoolers such as Stirling, Gifford–McMahon, and pulse tube cryocoolers possess great merits such as small size, low cost, high reliability, and good cooling capacity. These merits led them to meet many IR and superconducting based application requirements. The regenerator is a vital element in these closed-cycle cryocoolers, but the overall performance depends strongly on the effectiveness of the regenerator. This paper presents a one-dimensional numerical analysis for the idealized thermal equations of the matrix and the working gas inside the regenerator. The algorithm predicts the temperature profiles for the gas during the heating and cooling periods, along with the matrix nodal temperatures. It examines the effect of the regenerator’s length and diameter, the matrix’s geometric parameters, the number of heat transfer units, and the volumetric flow rate, on the performance of an ideal regenerator. This paper proposes a 2D axisymmetric CFD model to evaluate the ideal regenerator model and to validate its findings.

IC- (Integrated circuits) sorting machine is a kind of special equipment used for testing, classifying and grading IC chips, which is of significances in IC industry. Traditionally, IC- sorting machine is controlled by industry personal computer (IPC), which bears disadvantages such as large size and high cost. By contrast, the control system for IC-sorting machines presented in this paper is based on micro control unit (MCU), which is of relatively high reliability as well as high stability but low cost. First, we gave an outline of the configuration and operation principle of the sorting machine. Second, the input and output (I/O) signals that should be controlled were classified. Last but not least, the control strategy was presented both from the hardware side and the software side. In terms of the hardware design, touch screen was adopted as the human interface device (HID) for the sake of convenience, and isolated power module as well as optical isolated module were applied to improve the anti- electro magnetic interference (EMI) performance; In terms of software design, mechanisms such as multi-task by-turn and timer interrupt delay were adopted to improve the operation efficiency.

Nowadays, as a result of the serious shortage of parking spaces in major city all over China, people often feel it’s difficult to park their cars. Building mechanical parking garage has become an important way to solve this problem. Lifting and sliding mechanical parking garage is the most widely used mechanical parking garage. At present, lifting and sliding mechanical parking garage widely adopts centralized control system based on PLC. But there are several disadvantages in this kind of control system, suck as structural complexity, weak expansibility, and high cost. With the advantages of simple structure, strong expansibility, low cost and high reliability, CAN bus control system is widely used in the mechanical parking garage. The major mission of this paper is to study the control system of lifting and sliding mechanical parking garage based on CAN bus.
