(Askeri) DİYAFRAM: Bir optik sisteme giren ışık miktarını tayin eden fiziki unsur. Işık miktarı, görüntünün ebadına etki etmeden görüntünün parlaklığını belirler
(Tıp) Retroversion halindek uterus'u anteversion halinde tutma veya sarkan uterus ve vagina duvarlarını yukarı iterek ona destek temin etmek amacıyla vaginaya yerleştirilen lastik veya diğer bir maddeden yapılmı araç, peser
A floor slab, metal wall panel, roof panel or the like, havig a sufficiently large in-plane shear stiffness and sufficient strength to transmit horizontal forces to resisting systems
In mammals, a sheet of muscle separating the thorax from the abdomen, contracted and relaxed in respiration to draw air into and expel air from the lungs; also called thoracic diaphragm
a contraceptive device consisting of a flexible dome-shaped cup made of rubber or plastic; it is filled with spermicide and fitted over the uterine cervix
{i} partition separating the chest cavity from the abdomen (Anatomy); disk which vibrates in response to sound waves (in a telephone, speaker, etc.); shutter; birth control device
A stationary element between stages of a multistage centrifugal compressor It may include guide vanes for directing the flowing medium to the impeller of the succeeding stage in conjunction with an adjacent diaphragm, it forms the diffuser surrounding the impeller (020)
Generally a five hole disc placed under the stage on a high power microscope Each hole is of a different diameter By turning it, you can vary the amount of light passing through the stage opening This will help to properly illuminate the specimen and increase contrast and resolution The diaphragm is most useful at the higher powers
The mechanism controlling the size of the lens opening and therefore the amount of light that reaches the film It consists of several overlapping metal leaves inside the lens that form a circular opening of variable sizes (You can see it as you look into the front of the lens ) The size of the opening is referred to as the f-stop or aperture
large, concave muscle attached to the rib cage at bottom of the chest (top of the abdomen) Inhalation occurs when diaphragm contracts Exhalation is passive as the muscle relaxes
electro-acoustic transducer that vibrates to receive or produce sound waves a contraceptive device consisting of a flexible dome-shaped cup made of rubber or plastic; it is filled with spermicide and fitted over the uterine cervix (anatomy) a muscular partition separating the abdominal and thoracic cavities; functions in respiration
A diaphragm is a circular rubber contraceptive device that a woman places inside her vagina. Dome-shaped muscular and membranous structure between the thoracic and abdominal cavities. The principal muscle used in respiration, it is also important in coughing, vomiting, excretion, and other expulsive functions. Spasms of the diaphragm produce hiccups. The aorta passes behind the diaphragm; the inferior vena cava and esophagus pass through it. Protrusion of part of the stomach above the diaphragm is called a hiatal hernia
a mechanical device in a camera that controls size of aperture of the lens; "the new cameras adjust the diaphragm automatically" electro-acoustic transducer that vibrates to receive or produce sound waves a contraceptive device consisting of a flexible dome-shaped cup made of rubber or plastic; it is filled with spermicide and fitted over the uterine cervix (anatomy) a muscular partition separating the abdominal and thoracic cavities; functions in respiration
1 The radiating surface of a compression driver; it's vibrations emit sound waves 2 The moving element of a microphone Directivity: The ability of a speaker or horn to direct sound to a given area which can be described by its directivity factor (Q) Dispersion: The area throughout which the sound produced by a speaker is distributed Distortion: Any discrepancy between the source material and the sonic output of a sound system Dynamic Microphone: A microphone that converts sound into electrical pulses by means of a moving electromagnetic coil Dynamic Range: The difference between the softest and loudest extremes within an audio signal Dynamics Processing: The use of electronic devices to control the levels of audio signals and compress or expand their dynamic range
the side wall or bottom of an ultrasonic cleaning tank or the active surface of an immersible transducer or other radiating acoustic device that transmits ultrasonic energy from the stack or transducer into a liquid bath (analagous to the diaphragm in an early telephone), in effect thus forming the radiating surface - use of term in this fashion coined by Berliner - see text)
The part of the camera that governs the size of the aperture The most common type is the iris diaphragm - a system of curved, overlapping metal blades that form a roughly circular opening similar to the iris of the eye It varies in size to control the amount of light
Made out of glass, mica, paper, copper, or aluminum, the thin diaphragm is the part of the reproducer that vibrates to cause the record grooves to be heard as sound
A flexible membrane separating two chambers and fixed around its periphery that distends into one or other chamber depending on the as the difference in the pressure in the chambers varies
Lens opening A perforated plate or adjustable opening mounted behind or between the elements of a lens used to control the amount of light that reaches the film Openings are usually calibrated in f-numbers
In mammals, a sheet of muscle separating the thorax from the abdomen, contracted and relaxed in respiration to draw air into and expel air from the lungs
Flexible membrane in a valve which deflects down onto a rigid area of the valve body to regulate water flow from the supply lines The large diaphragm found in Kohler's Rite-Temp pressure-balancing valves is resistant to minerals and other debris often found in a water supply This eliminates the possibility of debris build-up within the valve
A plate with an opening, which is generally circular, used in instruments to cut off marginal portions of a beam of light, as at the focus of a telescope
A diaphragm is a thin dome-shaped skeletal muscle that separates the thoracic and abdominal cavities The diaphragm plays an important role in breathing: it contracts with each inspiration, becoming flattened downward and increasing the volume of the thoracic cavity so that air is drawn into the respiratory tract, and then, with expiration, it relaxes and is restored to its dome shape
a flexible sheet The diaphragm in the chest is a sheet of muscle that controls breathing Also refers to a flexible latex disk placed over the uterine cervix as a contraceptive device to form a barrier to sperm
There are diaphragms in ears (eardrum), microphones, loudspeakers, etc They either excite the air or are excited by it Their purpose is to increase the efficiency of sound energy transfer to and from a tenuous medium, such as air
