Generating, английский
A rapid roughing process to quickly remove material from a lens. accomplished by cutting tools on a machine. generator, free-form – a type of computercontrolled generator with at least three axes of movement that can cut most continuous lens surface shapes to a level of precision and smoothness that requires only minimal polishing with a free-form polisher. generator, traditional – a type of generator with either two or three axes of movement that can cut only basic spherical and sphero-cylindrical lens surface shapes to a minimal level of smoothness that requires additional fining with a cylinder machine.
Ultrasonic, английский
- Manufacturers` association ассоциация фирм — изготовителей изделий с использованием ультразвука
- Of or relating to acoustic vibration frequencies greater than about 20 khz.
- Pertaining to acoustic vibration frequencies greater than about 20 khz.
- Of or relating to acoustic vibration frequencies greater than about 20 khz.7,22
Transducer, английский
- A device that converts energy from one form to another, such as optical energy to electrical energy.
- Преобразователь, датчик, при?мник
- A device which converts power in one kind of system to power in another form, e.g., a loudspeaker which converts electric power to acoustic power.
- A device that converts one type of energy to another (e.g., water pressure to electricity, as in a speed recorder; or electrical to acoustic as in a loudspeaker).
- Первичный измерительный преобразователь, датчик
- A device that converts energy from one form to another, such as a microphone or speaker.
- An electrical device that converts a signal from one form of energy to another.
- Any device that is capable of converting energy from one form to another.
- (1) device that converts mechanical energy to electrical output or vice versa. (2) piezoelectric device that converts attributes of the stress-versus-strain field of an acoustic wave into an electrical signal of voltage versus time. sensor; probe. transducer, differential: piezoelectric twin-element or dual-pole transducer.
- Device by means of which energy can flow from one or more transmission systems or media to one or more other transmission systems or media; sensor or probe.4
- (1) device that converts mechanical energy to electrical output or vice versa. (2) piezoelectric device that converts attributes of the stress-strain field of an acoustic wave into an electrical signal of voltage versus time. sensor; probe.16 transducer, differential: piezoelectric twin-element or dual-pole transducer, the output poles of which are isolated from the case and are at a floating potential.16
Microphone, английский
- Микрофон
- A device which converts sound waves into essentially equivalent electric waves; the sound waves move an element in the device which generates an electric voltage.
- A device that converts sound into an electrical signal. common microphones include cardioid, ribbon, stereo, omnidirectional and condenser.
- A device that converts sound waves into analog electrical signals. additional hardware can convert the microphone’s output into digital data that a computer can process; for example, to record multimedia documents or analyze the sound signal.

Container, gamma-ray source (rt), английский
A device for housing radionuclides and giving a required degree of protection against radiation. (this may take the form of an exposure device or a storage container.)
Penetrameter (rt), английский
A device employed to obtain evidence on a radiograph that the technique used was satisfactory. it is not intended for use in judging the size of discontinuities nor for establishing acceptance limits for materials or products.
