Nilsson Kenth Dipl Ing, Bolmgren Jan: Liquid droplets recording device.. Siemens, October 26, 1983: EP0092229-A2 (251 worldwide citation)

In the recording device there is at least one nozzle for writing which is arranged in a holder. If required, writing liquid from the nozzle can be applied to a recording medium arranged in front of the outlet opening of said nozzle. In order to avoid undesired leakage of writing liquid from the nozz ...

Shaw Herbert John: Sensor using fiber interferometer.. Univ Leland Stanford Junior, October 26, 1983: EP0092367-A2 (72 worldwide citation)

A closed loop optical fiber interferometer is used in sensing a quantity, Q, by applying a time varying or modulated measure of, Q, asymmetrically to the closed loop (24) and detecting phase shift between two counterpropagating optical signals in the closed loop. The closed loop (24) can be used as ...

Mano Toshihiko, Kodaira Toshimoto, Oshima Hiroyuki: A thin film mos transistor and an active matrix liquid crystal display device. Suwa Seikosha, October 26, 1983: GB2118365-A (58 worldwide citation)

A thin film MOS transistor includes a silicon layer (202) whose thickness, at least in the channel region is less than 2500 ANGSTROM . The silicon layer may be a polycrystalline silicon layer and its thickness in the channel region may be less than its thickness in the source and drain regions. Such ...
