Internal Meshing

A new type of non-circular planetary gear train is proposed, in which the planetary gear is internally meshed with the sun gear and the ring gear at the same time. The structural form and transmission principle are analyzed, and the design method of non-circular gear pitch curves and related parameters of the gear train are discussed. The input–output relationship under various working conditions of the gear train is deduced. The precise tooth profile of the non-circular gears is obtained by the Boolean operation of MATLAB, then the virtual prototype model of the planetary gear train is established, and the kinematics simulation is carried out in the ADAMS software. The simulation results verify the correctness of the transmission principle and the theoretical analysis of the motion law.

Executive Mechanism

This paper introduces a simulation study on the executive mechanism of a recent invented controllable mechanism type novel planar 3-DOF mechanical excavator using simulation analysis software MSC.ADAMS. A virtual prototype model is established first, based on which the forward kinematics simulation is carried out employing the DIM functions to achieve an output trajectory similar to the excavating process of a flexible hydraulic excavator. Subsequently, an inverse kinematics simulation is performed accomplishing a given V type output trajectory. Angular displacements, velocities and accelerations of the three input variables are obtained. Results of the simulation study may provide some useful references for further researches such as dimensional synthesis, dynamics and design of the controller of the new type of mechanical excavator.

AbstractA novel field effect transistor (FET) that uses 3-dimensional (3-D) embedded gate fingers – the Screen-Grid Field Effect Transistor (SGFET) – is proposed. The gating action of the SGFET is based on the design of multiple gating cylinders into the channel region, perpendicular to the current flow. Such configuration allows a full 3-D gate control of the current which improves the device characteristics by increasing the gate to channel coupling. Initial investigations of the SGFET using 3-D TCAD TaurusTM simulation software are presented in this paper. The results indicate that the proposed SGFET offers the possibility of downscaling without degrading the output characteristics. A comparison between the SGFET and both bulk and SOI MOSFETs shows the superior characteristics of the SGFET for low power operation.

AbstractWe propose a novel formal framework (called 3D-NCDC-ASP) to represent and reason about cardinal directions between extended objects in 3-dimensional (3D) space, using Answer Set Programming (ASP). 3D-NCDC-ASP extends Cardinal Directional Calculus (CDC) with a new type of default constraints, and NCDC-ASP to 3D. 3D-NCDC-ASP provides a flexible platform offering different types of reasoning: Nonmonotonic reasoning with defaults, checking consistency of a set of constraints on 3D cardinal directions between objects, explaining inconsistencies, and inferring missing CDC relations. We prove the soundness of 3D-NCDC-ASP, and illustrate its usefulness with applications.

ABSTRACTIn this report, the newly developed three-dimensional magneto-optical (MO) recording scheme and the experimental results are reported. A part of this work has been done as the national project of 3D-MO (3-dimensional MO) project. It started at September 1998 and ended March 2002 as a part of the national project “Nanometer-Scale Optical High Density Disk Storage System” and aimed at achieving 100 Gb/in2 in storage density. Three-dimensional MO recording is one of the prosperous candidates of next generation ultra high density recording. Magnetic amplifying MO system (MAMMOS) is employed for achieving the novel three-dimensional MO recording. Double-MAMMOS scheme consists of 2-recording layers of differing compensation temperature (Tcomp ) and one readout layer was proposed and discussed.With write/read test it is succeeded to show the results corresponding to a 100 Gb/in2 (50 Gb/in2 × 2) recording density. We also proposed and showed results of simulations of a new type of Double-MAMMOS in which the recording layers can hold quadri-valued information by single writing process.

Abstract In this work, the motion differential equations for a multiple-point meshing mechanism with flexible support are established by the Lagrange formula, and solved using a Laplace transform approach. The stable conditions and the formula for calculating this system’s natural frequencies are given and the general dynamic responses, in analytical form, are developed. The analysis pays special attention to the zero state response to a step function and constant loading inputs. Furthermore, the dynamic torques acting on the basic shaft and torsional bar are also discussed. This research lays the foundation for the analysis and design of this new type of transmission mechanism.
