Definitions

  • a vibrating member for light ray oscillographs or the like comprising an electrically insulating carrier plate, a conductor spiral constituting an electric coil and formed on at least one of the faces of the plate by vapo-r deposition, a mirror carried by said plate, and suspension bands extending at opposed directions lengthwise of said plate and secured thereto.
  • the object of the invention is to provide an improved vibrating member for a light ray oscillograph or the like that may be manufactured in a highly automated manner with a high degree of uniformity.
  • the novel vibrating member comprises an electrically insulating carrier plate, the length dimension of which is preferably 30-40 times the dimension of its width, a preferably elongated conductor spiral constituting an electric coil disposed on the carrier plate and formed, e.g. by means of vapor deposition.
  • FIG. 1 is a frontal elevational view of an embodiment of the invention
  • FIG. 2 is a sectional elevational side view of another embodiment of the invention.
  • FIG. 3 is a cross-sectional view of a further embodiment of the invention.
  • FIG. 4 is a cross-sectional vie ⁇ w of another embodiment of the invention.
  • FIG. 5 is a partial isometric View of still another embodiment of the invention.
  • FIG. 6 is a partial isometric view of the element shown in FIG. 5.
  • the novel vibrating member comprises a base or carrier plate 1, the dimensions of which may be, for example, 12.2 x 0.34 x 0.1 millimeters.
  • the carrier plate may be made, for example, of hard glass or of semiconductive silicon coated with an electrically insulating thin oxide layer.
  • the carrier plate 1 On at least one of its large faces the carrier plate 1 is provided with a conductor 2 arranged in an elongated spiral configuration lying in a single plane and having a plurality of turns.
  • the conductor spiral 2 ends in an external terminal 2a and an internal terminal 2b, both being wider than the Width of conductor 2 forming the body of the spiral.
  • the inner terminal 2b extends centrally in the length direction of the plate 1 along almost the entire length of the innermost turn of the conductor spiral 2. This particular arrangement of inner terminal 2b makes possible a selective connection thereof to contact face 3a or 3b carried by plate 1 at either end of the conductor spiral 2.
  • the connection between terminal 2b and either contact face 3a or 3b is preferably made only during the installation of the vibrating member.
  • the conductor spiral 2 and the contact faces 3a, 3b may be formed on plate 1 by any appropriate technique known in the printed circuit art. It has been found that a coating technique, such as vapor deposition, is par'al ticularly advantageous since, by means of a preformed suitable mask, a great number of plates may be simultaneously treated. The process may be entirely automated.
  • the deposited conductor spiral, constituting the electricr coil of the vibrating member, is uniform to a very high degree. It is extremely thin and, consequently, it lies substantially in the plane of the plate face.
  • the conductor obtained by vapor deposition may, if conditions require, be subsequently reinforced by a galvanization step.
  • Plate 1 further carries, below the contact face 3a, a mirror 4 for deflecting the light rays of a light ray oscillograph.
  • Mirror 4 may also be formed by vapor deposition or may be bonded to plate 1 as a preformed thin refleeting member.
  • FIG. 2 there are shown two carrier plates 1 bonded together in a face-to-face relationship.
  • Each plate carries on both faces a conductor Spiral 2 connected in parallel or in series through apertures 5 disposed in the line of symmetry of the plate 1.
  • Sandwiched between the two carrier plates 1 are two suspension bands 6 extending lengthwise in opposed directions at both ends of the member.
  • the conductor spirals of the two carrier plates 1 are also interconnected. It is preferred to make the parallel or serial connections between the conductor spirals on opposed faces of carrier plates 1 only during the installation of the vibrating member.
  • Vibrating members adapted to oscillate at elevated frequencies are usually disposed n a damping fluid.
  • a damping fluid In order to provide an evenly-exposed surface in the damping fluid and thus avoid deviations in the damping effect, it was found expedient to round out the angular shape of the plate stock.
  • a stack of six carrier plates 1 bonded together (each plate being provided at least on one face thereof with a conductor spiral, not shown for clarity) is embedded in a rounded envelope 7 made, for example, of synthetic resin.
  • the suspension the other end of band is sandwiched between the two innermost carrier plates 1.
  • the stack instead of being embedded in a synthetic resin envelope, the stack (consisting here of four carrier plates 1) is inserted into a thin walled glass sleeve 8.
  • FIG. 5 there is shown one end portion of a further embodiment of a single-plate carrier member. It is seen that a suspension band 6 is soldered to the contact face 3a which is further electrically connected by strip 9 to the outer terminal 2a of the conductor spiral 2. To the other contact face 3b, which is shown in FIG. 6, there is also soldered a suspension band 6. To the polished or smoothened small face or edge 1a of carrier plate 1 trere is bonded or deposited a mirror 10.
  • the novel vibrating member as described hereinabove is installed and held in a light ray oscillograph or like instrument in such a known manner that it may oscillate, usually about its longitudinal axis of symmetry, upon the action of a varying magnetic eld on conductor spirals 2 constituting the vibrating electric coils.
  • a light ray oscillograph or like instrument of the type including at least one vibrating :member of rounded cross-section, said vibrating member having a coil, a mirror, and suspension means, the improvement in said vibrating member comprising a plurality of carrier plates secured together in a face-to-face relationship to form a stack, said stack and mirror being disposed within a transparent sleeve, and a conductor spiral constituting said coil disposed on at least one face of each of the said plates, said conductor spiral lying in a single plane substantially coplanar with said face.
  • the improvement as defined in claim 1 includin two contact faces carried by each of the said plates and each disposed at diametrically opposed sides of said conductor spiral and adapted to be electrically connected to each end of said spiral.
  • each of the said plates carries on opposed faces thereof at least one of said spirals, at least one aperture provided in each of the said plates in the centerline thereof adapted to receive means electrically interconnecting said spirals on said opposed faces of said plate.
