a new bonding technique utilizing nano-scaled particles for use in high-temperature environments. The results of our investigations revealed that the method could be used to form bonds by simultaneously applying heat and pressure. Moreover, compared to a conventional Pb“5Sn-solder bond, a nanoparticle-based bond suffered no degradation in bonding strength over an elevated-temperature holding period of 1000 h at 250 °C, and its discharge characteristics were improved (i.e., increased) threefold. It is possible to extend this bondi ....etc

Helical Gear
What is helical gear ?
Helical gear is the type of gears .
Helical gear is a cylindrical shaped gear with helicoid teeth. Helical gears operate with less noise and vibration than spur gears .
Helical gears can be meshed in a parallel or crossed orientations.
The angled teeth engage more gradually than do spur gear teeth causing them to run more smoothly and quietly
Types of Helical gear-
1. Cross helical gears

1. INTRODUCTION

There is a saying in real estate; when land get expensive, multi-storied buildings are the alternative solution. We have a similar situation in the chip industry. For the past thirty years, chip designers have considered whether building integrated circuits multiple layers might create cheaper, more powerful chips.

Performance of deep-sub micrometer very large scale integrated (VLSI) circuits is being increasingly dominated by the interconnects due to increasing wi ....etc

Gears, Gears and More Gears
What is a gear?
A gear is a wheel with teeth that mesh together with other gears.
Gears change the
• speed
• torque (rot. force)
• direction of rotating axles.
Different types of gears
Spur gears
Idler gears
Worm gears
Bevel gears
Belts & Pulleys
Spur Gears
Most “common” type of gear, a wheel with teeth
Spur gears do three things.
1. Change rot. speed
2. Change torque
3. Change direction
Make sure there isn’t too much friction between th ....etc

1.0 INDRODUCTION
An escalator is a moving staircase conveyor transport device for carrying people between floors of a building. The device consists of a motor-driven chain of individual, linked steps that move up or down on tracks, allowing the step treads to remain horizontal.
Escalators are used around the world to move pedestrian traffic in places where elevators would be impractical. Principal areas of u ....etc

ABSTRACT

The unprecedented growth of the computer and the Information

technology industry is demanding Very Large Scale Integrated (VLSI) circuits

with increasing functionality and performance at minimum cost and power

dissipation. VLSI circuits are being aggressively scaled to meet this Demand,

which in turn has some serious problems for the semiconductor industry.

Additionally heterogeneous integration of different technologies in one

single chip (SoC) is becoming increasingly desirable, for which planar ....etc

ABSTRACT
Smart pixels, the integration of photodetector arrays and processing electronics on a single semiconductor chip, have been driven by its capability to perform parallel processing of large pixelated images and in real-time reduce a complex image into a manageable stream of signals that can be brought off-chip. In recent years, optical modulators and emitters have been integrated with photodetectors and on-chip electronics. The potential uses for smart pixels are almost as varied as are the designs. They can be used ....etc
