Title: Method for producing glass preform for optical fiber
Inventor: KYOTO MICHIHISA
IPC: G02B6/00
Filed: 1985-06-07
Granted: 1991-04-30
Abstract: Abstract:         The invention provides a method for producing a GeO2-SiO2 type glass preform for an optical fiber.  The method comprises dehydrating a porous soot preform made of GeO2-SiO2 fine glass particles in an atmosphere of oxygen containing a fluorine-containing compound at such a temperature that the preform does not drastically shrink, and then sintering the soot preform in an atmosphere comprising helium at such a temperature that the preform is made transparent.  By this method, contamination with impurities, residual water and bubbles in the optical fiber and irregularities of the surface of the optical fiber are greatly reduced.

Abstract: ABSTRACT     An implantable medical device for controlling a physiological function includes functional apparatus for controllably duplicating the selected normal physiological function of the patient's body.  A sensor detects the physical orientation of the implanted medical device within the body, which is indicative of whether the patient is standing, sitting or reclining.  The sensor is also responsive to forces of acceleration on the medical device within the body, indicative of the state of rest or activity movement of the patient.  Apparatus in the device is responsive to the physical position and the physical state of the patient, as detected by the sensor, to control the duplication of the normal physiological function according to that position and state.  In one embodiment, the medical device is a cardiac pacemaker and the physiological function is heart rate.  The sensor of that embodiment includes a chamber, a mercury ball confined within the chamber, and a multiplicity of electrodes within the chamber for making or not making electrical contact with the ball to signify the physical orientation of the medical device.  The electrodes are disposed about a surface of the chamber against which the ball normally resides, such that movement of the patient causes movement of the ball and interrupted makings of contact between electrodes.

The transport means engages the continuous strip of coverstock material along the free longitudinal edges thereof.  The transport means is actuated to advance the continuous strip and, hence, each successive piece of substrate laminated thereto from the lamination station into the thermoforming station.  The thermoforming line optionally comprises additional stations, such as ornamentation stations, trim stations, and the like.  Additional material may be included in the lamination such as, for example, padding-type materials between the coverstock and the substrate, an additional sheet of coverstock on the opposite side of the substrate sheetstock, and the like.
