Abstract: An apparatus for detecting ophthalmic diseases such as an inflammation in a patient's eye (11) which includes means (7,9) for focusing a laser beam (1) at a selected spot (P) in the eye. The light scattered from the eye is photoelectrically detected and converted (27) into an electrical signal which is subsequently used to determine the protein concentration essential to ophthalmic disease detection in the patient's eye. The laser beam (1) is deflected vertically and horizontally (4, 4'). The electrical signal derived from the vertical scanning is compared with the other electrical signals from the horizontally shifted scanning of the laser beam to remove noises from the electrical signal.

Abstract: An electrically-erasable, programmable ROM cell, or an EEPROM cell (10), is constructed using an enhancement transistor merged with a floating-gate transistor, where the floating-gate transistor has a small tunnel window (19), in a contact-free cell layout, enhancing the ease of manufacture and reducing cell size. The bitlines (13) and source/drain regions (15,16) are buried beneath relatively thick silicon oxide (14), which allows a favorable ratio of control gate (12) to floating gate (17) capacitance. Programming and erasing are provided by the tunnel window area (19) near or above the channel side of the source (15). The window (19) has a thinner dielectric than the remainder of the floating gate (17), to allow Fowler-­Nordheim tunneling. By using dedicated drain (16) or ground lines, rather than a virtual-ground layout, and by using thick oxide (22) for isolation between bitlines (13), the floating gates (17) can extend onto adjacent bitlines (13) and isolation areas (22), resulting in a favorable coupling ratio. Bitline (13) and wordline (12) spacing may be selected for optimum pitch or aspect ratio. Bitline (13) to substrate (11) capacitance is minimized. Isolation between cells (10) in the bitline (13) direction is by thick thermal oxide regions (22). Isolation between cells (10) in the wordline (12) direction is by thick thermal oxide regions (21).

Abstract: A magnetron sputtering apparatus is formed with a plurality of cells (A, B, C, D) each for generating an independent magnetic field within a different region in the chamber (13′) of the apparatus. Each magnetic field aids in maintaining an ion plasma in the respective region of the chamber. One of a plurality of sputtering material targets (34-37) is positioned on an electrode (60) adjacent to each region so that said ions strike the target ejecting some of the target material. By selectively generating each magnetic field, the ion plasma may be moved from region to region to sputter material from different targets. The sputtered material becomes deposited on a substrate (19′) mounted on another electrode within the chamber. The duty cycle of each cell can be dynamically varied during the deposition to produce a layer having a graded composition throughout its thickness.

Abstract: In a coin sorter of the kind in which coins of mixed denomination are sorted between a notating resilient disc and a sorting head, stacked coins are broken up and the excess coins recirculated prior to referencing a single-file stream of coins to a fixed radial position and recirculating excess coins that are not properly referenced. By recirculating the coins in these two different circumstances, the breaking up of the stacked coins does not hinder the referencing of the coins, and consequently the possibility of miss-sorting due to stacked coins is reduced and the sorting speed is increased, especially when sorting predominately small thin coins such as dimes. To increase the sorting speed when small thin coins are mixed with large thick coins, the large thick coins are preselected before being referenced together with the coins of other denominations. Preferably, thick coins which are not initially referenced to an extreme outward radial position are recirculated prior to reaching the means for breaking up double coins, since such thick coins would otherwise hinder the flow of thin coins to the referencing means.
