Website. gate2025.iitr.ac.in (for GATE 2025) The Graduate Aptitude Test in Engineering (GATE) is an entrance examination conducted in India that tests the undergraduate subjects of engineering and sciences for admission to technical postgraduate programs. GATE is conducted jointly by the Indian Institute of Science and seven Indian Institutes ...
Logic gate. A logic circuit diagram for a 4-bit carry lookahead binary adder design using only the AND, OR, and XOR logic gates. A logic gate is a device that performs a Boolean function, a logical operation performed on one or more binary inputs that produces a single binary output. Depending on the context, the term may refer to an ideal ...
Gate Blush: Halo or Blush Marks Circular pattern around gate, normally only an issue on hot runner molds Injection speed is too fast, gate/sprue/runner size is too small, or the melt/mold temp is too low. Jetting: Jetting is a snake-like stream which occurs when polymer melt is pushed at a high velocity through restrictive areas.
Inverter (logic gate) Traditional NOT gate (inverter) symbol. In digital logic, an inverter or NOT gate is a logic gate which implements logical negation. It outputs a bit opposite of the bit that is put into it. The bits are typically implemented as two differing voltage levels.
Mechanical engineering is the study of physical machines that may involve force and movement. It is an engineering branch that combines engineering physics and mathematics principles with materials science, to design, analyze, manufacture, and maintain mechanical systems. [1] It is one of the oldest and broadest of the engineering branches.
The two main gate systems are manually trimmed gates and automatically trimmed gates. The following examples show where they are used: Sprue gate: Used for large components, the gate mark is visible in component and no runner is required. e.g.: bucket molding (backside cylindrical gate mark visible and can be felt).
Diameter of a circle. In a feature control frame (FCF), the ⌀ symbol tells you that the tolerance zone for the geometric tolerance is cylindrical. Abbreviations for "diameter" include ⌀, DIA, and D. D. diameter; delta. Abbreviations for "diameter" include ⌀, DIA, and D. For delta usage, see for example "delta notes".
The AND gate is a basic digital logic gate that implements logical conjunction (∧) from mathematical logic – AND gate behaves according to the truth table. A HIGH output (1) results only if all the inputs to the AND gate are HIGH (1). If not all of the inputs to the AND gate are HIGH, a LOW output results. The function can be extended to ...
