Granted: 1991-03-05
Abstract: Abstract An optical fiber system which includes a source of electromagnetic radiation, e.g., a laser, in optical communication with a multicomponent halide glass optical fiber is disclosed. This system is distinguished from previous such systems in that, within the context of the inventive system, the multicomponent halide glass fiber exhibits lower intrinsic loss than when used in previous such systems. This is achieved by choosing the source in relation to the composition of the fiber so that the wavelength of at least a portion of the electromagnetic radiation emitted by the source is substantially equal to the minimum intrinsic loss wavelength for the fiber, as determined using a new, more accurate procedure.

Title: Imaging charge-coupled device having an all parallel output
Inventor: RILEY LARRY D
IPC: H04N5/372
Filed: 1988-09-13
Granted: 1991-09-17
Abstract: Abstract A charge-coupled device comprises a substrate of semiconductor material having at least two buried channels formed therein.  At least two sets of clock electrodes overlie the buried channels.  By appli-cation of appropriate potentials to the clock elec-trodes, an electrical charge may be propagated in controlled fashion along each buried channel to-wards its output end.  A floating diffusion is formed at the output end of each buried channel for receiving charge propagated along the channel.          Output transistors are associated with the buried channels respectively and each has a control elec-trode connected to the floating diffusion of the associated channel.  An output diffusion is located between the floating diffusions and the control electrodes of the transistors and extends perpen-dicular to the channels.  A reset gate is as-sociated with each channel and lies over the sub-strate between the floating diffusion of the as-sociated channel and the output diffusion, so that by application of a predetermined potential to the reset gate a conductive channel is formed in the substrate between the floating diffusion of the associated channel and the output diffusion. A reset bus extends over the substrate on the op-posite side of the floating diffusions from the reset gate and has a bus extension which extends over the substrate between the floating diffusions and is connected to the reset gates.

Abstract: Abstract A hydraulic safety brake valve arrangement for a motor (1) that is loadable by an external force  (F)  comprises a main valve (115).  It forms a first throttling point (118) in the supply motor conduit (5b) and a second throttling point (119) in the delivery motor conduit (6b).   The openings of both throttling points (118,  119) change in the same sense.   At least during braking operation,  they depend on  the  flow  (C)  through  the first  throttling point  (118). The  second  throttling  point (119) is in series with a compensating valve (116) which holds the pressure drop at the second throttling point (119) constant.          Further,  the connection (24) of the second  throttling  point (119) on the container side can be connected by way of a refill check valve (25) to the connection (21) of the first throttling point (118) on the motor side.   This results in a constant deceleration under the influence of the external  load.    In addition, cavitation effects are avoided.          Fig. 2

Granted: 1993-07-20
Abstract: Abstract of the Disclosure A process and device for preparing a stretched film by passing a tubular thermoplastic film into pairs of nip rolls having different peripheral speed and by inflating an obtained bubble with internal pressure under heating, wherein the pairs of nip rolls comprise at least three pairs of nip rolls designated with R1, R2 and R3, respectively, pressurized air is admitted into the stretched bubble situated between the rolls R1 and R2 through a slit-like air injecting nozzle provided in a gap between the pair of rolls of R2, and the bubble formed by the supplied pressurized air is inflated and stretched under heating.  In this stage, if desired, the amount of injected pressurized air is controlled by manual control or automatic control by detecting the diameter of the bubble so as to keep the bubble's diameter constant.  After stretching, the film is collapsed with a collapser device and is introduced to the nip rolls of R2, both side ends of the collapsed film is cut open with film cutting knives positioned between the pair of nip rolls of R2 to make two sheets of flat films, and then, the flat films are introduced to left and right guide rolls so as to avoid interference with the slit-like injecting nozzle and the cutting knives.          Finally, the films are drawn with the nip rolls of R3.          In the device of the present invention, the diameter and internal pressure of the bubble can be controled with manual or automatic control during the tubularly stretching, and particularly, the device can be suitably applied to tubularly stretching of pourus films.
