mechano-|ˈmɛkənəʊ|
repr. Gr. µηχανο-, comb. form of µηχανή machine n., and used in the senses (a) ‘machine(s)’, as in mechanology, (b) ‘mechanical (and)’, as in mechanotherapy, mechanochemical a. Also ˌmechanoˈcaloric a. Physics [caloric a.], applied to the phenomenon by which a flow of the superfluid form of liquid helium (helium II) generates a difference in temperature between the sending and receiving ends; ˌmechano-eˈlectric, -eˈlectrical adjs., pertaining to or producing a conversion of mechanical movements into corresponding electrical effects; also ˌmechano-elecˈtronic a. (rare).
1939Mendelssohn & Daunt in Nature 29 Apr. 720/1 The mechano-caloric effect is evidently the reverse of the ‘fountain phenomenon’, for whereas the latter means that the setting up of a temperature difference results in a flow of liquid helium II, the mechano-caloric effect shows that a flow of liquid helium II is accompanied by a development of heat (or cold). 1964New Scientist 24 Sept. 773/1 Shortly after the discovery of this ‘thermo-mechanical’ effect the complementary ‘mechano-caloric’ phenomenon was observed.
1958Jrnl. Gen. Physiol. XLI. 1245 (heading) The sites for mechano-electric conversion in a pacinian corpuscle. Ibid. 1263 The simplest interpretation of our results would seem to be that the entire mechano-electric transducer lies in the membrane of the non-myelinated ending. 1974Nature 1 Mar. 69/2 Isometric tension was measured with two RCA 5734 mechano-electric transducers.
1961M. L. Gayford Acoustical Techniques & Transducers vi. 279 Trying to obtain a perfect electrical copy of the groove excursion by the mechano-electrical groove-following means provided by a gramophone pick-up. 1974Nature 20–27 Dec. 728/1 The muscle fibre was..mounted horizontally with one of its tendons hooked to the anode of a RCA 5734 mechano-electrical transducer tube.
195018th Internat. Physiol. Congr. Copenhagen 171 The movements of the membrane..are communicated to the plate of a mechano-electronic transducer (R.C.A. 5734), a triode which by means of a pivoted anode translates mechanical movements into electric current variations. |
