read moreAnswering questions related to JFET, SCR, impurity in semiconductor, gates, IC fabrication, resistivity of silicon, and transistors.
JFET terminals are Gate, Drain, and Source.
SCR terminals are Anode, Cathode, and Gate.
Increasing impurity in intrinsic semiconductor decreases breakdown voltage.
MOSFET gate is used as an inverter.
Diffusion of resistors is difficult to fabricate in IC.
Resistivity of pure Silicon is around 2300 ohm-cm.
A transistor is made of two diodes.
Q2. Tell me types of press tool
Press tools are used in manufacturing to shape and cut materials. There are various types of press tools.
Blanking tool
Piercing tool
Bending tool
Drawing tool
Forming tool
Coining tool
Embossing tool
Extrusion tool
Q3. Cutting clearance for Fine tool
Cutting clearance for fine tool is crucial for precision and accuracy.
Cutting clearance should be minimal for fine tools to prevent deflection and ensure accuracy.
The clearance should be determined based on the material being cut and the tool being used.
For example, a carbide end mill may require a smaller clearance than a high-speed steel tool.
The cutting speed and feed rate should also be considered when determining the clearance.
Regular maintenance and inspection of the to...read more
Q4. Calculate the press force
To calculate press force, multiply the area of the part being pressed by the pressure applied.
Determine the area of the part being pressed
Determine the pressure being applied
Multiply the area by the pressure to get the press force
Press Force = Area x Pressure
Q5. Draw the basic tool structure
The basic tool structure consists of a handle, shank, and working end.
The handle is the part held by the user and provides grip and control.
The shank connects the handle to the working end and may be straight or angled.
The working end is the part that performs the intended task, such as cutting or drilling.
Examples include a hammer with a wooden handle, a screwdriver with a metal shank, and a saw with a toothed working end.
Q6. What is the definition of communication?
Communication is the exchange of information between individuals or groups through verbal, non-verbal, or written means.
Communication involves the sharing of thoughts, ideas, and emotions.
It can be verbal (speaking), non-verbal (body language), or written (emails, letters).
Effective communication requires active listening and clear expression of thoughts.
Examples include conversations, presentations, emails, and text messages.
Q7. What is a component?
A component is a part or element of a larger system or machine.
A component is a physical or logical part of a system that can be replaced or exchanged.
Components work together to form a complete system or product.
Examples of components include resistors, capacitors, and transistors in an electronic circuit.
