  • Patent number: 6103573
    Abstract: An EEPROM system having an array of memory cells that individually include two floating gates, bit line source and drain diffusions extending along columns, steering gates also extending along columns and select gates forming word lines along rows of floating gates. The dual gate cell increases the density of data that can be stored. Rather than providing a separate steering gate for each column of floating gates, an individual steering gate is shared by two adjacent columns of floating gates that have a diffusion between them. Processing methods of forming such a cell array include two etching steps to separate strips of conductive material into individual floating gates that are self-aligned with source/drain diffusions and other gate elements. In one embodiment, this is accomplished by two etching steps with separate masks.

  • Patent number: 6100110
    Abstract: A thermistor chip is made by first forming first metal layers with a three-layer structure at both end parts of a thermistor block and then forming second metal layers with a three-layer structure on the first metal layers so as to have edge parts that are formed directly in contact with a surface area of the thermistor block and will reduce its normal temperature resistance value. The first and second metal layers are each of a three-layer structure with a lower layer made of a metal with resistance against soldering heat, a middle layer made of a metal with both wettability to solder and resistance against soldering heat, and an upper layer made of a metal having wettability to solder.

  • Patent number: 6099224
    Abstract: A paper supplying apparatus has a rotatable member around a horizontal axis, a pair of clamp plates supported by this rotatable member mutually parallel and in face-to-face relationship for clamping a book block in between, and guide plates each attached to an associated one of these clamp plates, extending downward from the clamp plates to a lower edge part of the book block when the book block is held vertically. Such a paper supplying apparatus can be removably connected to a book binding machine by attaching a guide rail to an outer wall of the book binding machine and a runner to the paper supplying apparatus. The runner is slidably engageable with the guide rail, allowing the paper supplying apparatus to move along the guide rail selectably towards or away from the book binding machine.

  • Patent number: 6099161
    Abstract: A method for use with digital automated test equipment for measuring an asynchronous analog frequency, which analog frequency may be up to at least four times the operational frequency of the digital automated test equipment. From test vectors related to the frequency of interest known to represent good components, a pattern of test vectors with randomly assigned timing sets is created. Then, the maximum number of counts and the period increment is set. The selected pattern of test vectors are then applied to the unit under test and the received waveforms compared to the stored patterns. If there is no match, the period of the timing sets within the frequency range of interest is adjusted by a predetermined increment, and the test is repeated until there is a match. Since the period is now known, the frequency of the asynchronous analog signal can be calculated.

  • Patent number: 6091633
    Abstract: As a specific application of a new memory architecture, an array of non-volatile dual floating gate memory cells is arranged on a semiconductor substrate with global bit lines extending in a column direction that are either permanently connected, or connectable through transistor switches, to short source and drain diffusions that are oriented in the row direction between the global bit lines. Multiple columns of memory cells are positioned between the global bit lines. Bit selection lines oriented in the column direction are connected to the gates of select transistors within the memory cells. Word lines individually extend over one or two rows of floating gates. This arrangement provides a very small array that allows for future scaling. It also enables the use of metal lines strapped to the global bit line diffusions, and to polysilicon word lines to reduce their resistance, without imposing their larger pitch on other array elements.

  • Patent number: 6088994
    Abstract: A form-fill-seal packaging machine produces a dummy bag from a film by starting to move seal jaws after the film has been pulled over a specified length or for a specified length of time from the moment when an eye mark on the film is detected by a detector. If the position on the film at which it was cut is displaced from the intended position, this displacement is inputted such that the specified length or the specified length of time is automatically corrected. If any of the parameters defining the pattern of transverse sealing operation is changed, the specified length or the specified length of time can also be automatically adjusted.

  • Patent number: 6088166
    Abstract: GRIN lenses are made by an ion/exchange process. In order to make a GRIN lens whose gradient index varies slowly radially, a cylindrical glass rod of a sufficiently large diameter is immersed in a salty bath. The size of the lens may be reduced by grinding, polishing or chemically etching away a peripheral optically dispensable portion of the lens away from the axis of the lens so that the outer diameter of the lens is as small as 0.8 millimeters. When such a smaller lens is used in optical components such as circulators, switches, WDM's and isolators, such optical devices would also be reduced in size to fit within a limited space.

  • Patent number: 6081447
    Abstract: A mass storage system made of flash electrically erasable and programmable read only memory ("EEPROM") cells organized into blocks, the blocks in turn being grouped into memory banks, is managed to even out the numbers of erase and rewrite cycles experienced by the memory banks in order to extend the service lifetime of the memory system. Since this type of memory cell becomes unusable after a finite number of erase and rewrite cycles, although in the tens of thousands of cycles, uneven use of the memory banks is avoided so that the entire memory does not become inoperative because one of its banks has reached its end of life while others of the banks are little used. Relative use of the memory banks is monitored and, in response to detection of uneven use, have their physical addresses periodically swapped for each other in order to even out their use over the lifetime of the memory.

  • Patent number: 6081325
    Abstract: In an optical scanning system for detecting particles and pattern defects on a sample surface, a light beam is focused to an illuminated spot on the surface and the spot is scanned across the surface along a scan line. A detector is positioned adjacent to the surface to collect scattered light from the spot where the detector includes a one- or two-dimensional array of sensors. Light scattered from the illuminated spot at each of a plurality of positions along the scan line is focused onto a corresponding sensor in the array. A plurality of detectors symmetrically placed with respect to the illuminating beam detect laterally and forward scattered light from the spot. The spot is scanned over arrays of scan line segments shorter than the dimensions of the surface. A bright field channel enables the adjustment of the height of the sample surface to correct for errors caused by height variations of the surface.

  • Patent number: 6078018
    Abstract: Sorting apparatus has a conveyor belt or equivalent mechanism for moving particles at a speed sufficient to generate a stream of particles in air, which particles can be graded such that selected material can be removed. The grading or sorting is conducted by a primary scanning system for analysing light reflected from particles in the stream in a plurality of wavelength ranges. Ejectors for removing particles from the stream are disposed downstream of the scanning system, and are instructed in response to signals received from the scanning system. An auxiliary scanning system is also included to establish the presence of material in the stream, and in the event that a void is detected in a given region, then the analysis of that region by the primary scanning system and any corresponding activation of the ejectors is inhibited.
