Title: Optical drop-and-insert apparatus
IPC: H04B10/142
Filed: 1990-02-27
Abstract: Abstract of the Disclosure An optical drop-and-insert apparatus which can process an optical signal in the form of an optical signal without converting the optical signal into an electric signal.  The optical drop-and-insert apparatus expands the pulse width of an optical data pulse in an optical data pulse train on an optical highway and drops the optical data pulse to form an empty bit at the bit of the optical data pulse or another bit so that a new optical data pulse may be inserted into the empty bit.          Miniaturization of the apparatus and increase in processing speed can be attained by enabling processing of an optical signal while it remains in the form of an optical signal.

Title: Image-forming material and process for forming images
Inventor: NISHIMURA KAORU
IPC: G03F7/004
Filed: 1990-03-15
Abstract: ABSTRACT OF THE DISCLOSURE       Disclosed herein are an image-forming material and a process for forming images, which can be applied to second originals used in the field of designing and drawing.     The  image-forming material  comprises  a  roughened plastics  film substrate and a transparent resin layer, colored resin layer, and photosensitive resin layer formed one over another (in the order mentioned) on the roughened surface  of  the  substrate,  said  three  layers  being  so designed as to be removed completely by dissolution or swelling during development after exposure to active rays.          It permits the formation of a colored relief image without any dyeing step and gives rise to a good image free of base  fogging without  causing any  decrease  in printing sensitivity.     The process for forming images comprises exposing the above-mentioned image-forming material to active rays and  subsequently  developing  the  exposed  image-forming material   with   two   kinds   of   developing   solutions consecutively,  thereby forming a colored positive relief image  on  the  roughened  plastics  film  substrate,  said development causes the exposed parts of the transparent resin layer, colored resin layer, and photosensitive resin layer to be removed by dissolution or swelling.

Abstract: A   selectively   self-locking   deadbolt   latch   for incorporation into doors or the like.   The latch can be preliminarily "armed" such that as the door closes the bolt will extend into the opening of the door strike.  The latch mechanism includes a cam lever having a shoulder which loads against the bolt extension.  A compression spring within the bolt urges the bolt towards the locked position once the cam lever is released from the bolt extension by closing the door.  The temporary retraction of the bolt as it engages the door strike releases the bolt and cam lever.   A beam spring acting on the cam lever urges the cam lever forward towards the locked position.  The bolt is initially armed by turning the inner turn lever slightly or by depressing the end of the bolt which includes chamfered edges to allow the bolt to move past the door strike for release.

Abstract: ABSTRACT OF THE DISCLOSURE    An absorbent pad has a cover formed of non-woven fibrous material,  which  is coated with a  fluorocarbon polymer and odor absorber(s).  The cover sheet is apertured around  a  critical  zone  to  overcome  undesired  surface tension  effects.    The  method  of  producing  the  cover includes providing a water-based mixture that includes 1% by weight of a fluorocarbon composition.  An odor absorbing reagent is added to the mixture which then is applied to a nonwoven web of fibrous material.  The treated web is dried to remove the excess water from the mixture,  and the fluorocarbon composition component  is  cured to  form a hydrophobic coating around the reagent and to bind the reagent to the web.   The drying and curing steps can be accomplished  by  applying  a  flow  of  air  heated  to  a temperature in a range from about 100°C to about 120°C to the web until the water has been removed.

Title: Fiber-optic strain gauge manometer
Inventor: BOCK WOJTEK J
IPC: G01L9/00
Filed: 1991-09-04
Abstract: ABSTRACT OF THE DISCLOSURE:         A fiber-optic strain gauge manometer and a method thereof  are for measuring  pressure  of  a  fluid,  to be respectively connected to a light source and a measurement apparatus. The manometer comprises:   a cylindrical hollow body, acting as a pressure transducer, having an inlet by which  the  fluid  can  get  inside,  free  ends  such  that longitudinal and circumferential strains are generated in the hollow body by the pressure of the fluid, thereby producing a dilatation of the hollow body; and a highly birefringent optical fiber having a sensing portion bonded to the outer surface of the hollow body along a longitudinal path such that its birefringence changes when the sensing portion is subjected to the dilatation of the hollow body. A polarized light beam is generated by the light source and transmitted in a form of two polarization eigenstates each parallel to one of two parallel principal birefringence axes of  the  birefringent  optical  fiber.     The  state  of polarization of the input light beam, being strain-modulated after a passage in the sensing portion of the birefringent optical fiber is collected by the measurement apparatus for detecting and measuring change in the birefringence as a function of the dilatation, thereby giving indication of the pressure inside the hollow body.  This fiber-optic strain gauge manometer can be used for measuring pressure up to at least 100 MPa.
