  • Patent number: 5547884
    Abstract: Field oxide films are formed on a semiconductor substrate of first conductivity type to be spaced from each other in the stripe shape. Gate insulating films are formed on the semiconductor substrate between the field oxide films. Word lines or control gate electrodes are formed on the field oxide films and the gate insulating films to be spaced from each other in the stripe shape along a direction perpendicular to the field oxide films. Grooves are formed in the gate insulating films and the field oxide films sandwiched by the word lines. Source regions of second conductivity type are formed in the semiconductor substrate in the grooves formed in the gate insulating films. A common source wiring region of second conductivity type for electrically connecting the respective source regions is formed in the semiconductor substrate in the grooves formed in the field oxide films.

  • Patent number: 5545926
    Abstract: A first contact hole for a bit line is formed in an interlayer insulating film, and a polysilicon film is formed on the inner surface of the contact hole and on the interlayer insulating film. Subsequently, the polysilicon film is subjected to isotropic dry etching using a resist as a mask, and the interlayer insulating film is subjected to RIE etching, thereby forming a second contact hole in the interlayer insulating film in a peripheral circuit region. Then, a laminated film is formed on the inner surface of the second contact hole and on the polysilicon film, and the second contact hole is filled with a filling member. The laminated film and the polysilicon film are patterned, thereby forming a bit line in a memory cell region.

  • Patent number: 5546010
    Abstract: The invention relates to a method for measuring a resistance value in a network incorporated in an electrical apparatus, wherein the network has at least two accessible terminals, the network has at least two time constants differing mutually by at least one order of magnitude, and the resistance value can be related to the voltage applied to the terminal clips and the current flowing through the apparatus.Such control switches are poorly accessible.Direct measurement is time-consuming as a result of the large value of the time constants. These problems are diminished by applying a step-like change of the voltage to the terminal clips, measuring the current flowing through the terminal clips before the change has taken place and after the transient phenomenon related to the smallest time constant and caused by applying the change is damped, and calculating the first resistance value from the measured values of the current.

  • Patent number: 5544649
    Abstract: An ambulatory (in the home) patient health monitoring system is disclosed wherein the patient is monitored by a health care worker at a central station, while the patient is at a remote location. The patient may be a person having a specific medical condition monitored or may be an elderly person desiring general medical surveillance in the home environment. Cameras are provided at the patient's remote location and at the central station such that the patient and the health care worker are in interactive visual and audio communication. A communications network such as an interactive cable television is used for this purpose. Various medical condition sensing and monitoring equipment are placed in the patient's home, depending on the particular medical needs of the patient. The patient's medical condition is measured or sensed in the home and the resulting data is transmitted to the central station for analysis and display.

  • Patent number: 5545906
    Abstract: A non-volatile semiconductor device comprises a memory cell having a P-type silicon substrate, an N-type diffusion region formed in the substrate and serving as a word line, N-type diffusion region one serving as a source and the other as a drain of the cell transistor, a floating gate extending from a region above the diffusion region over a region above between diffusion regions, and a bit line connected to the diffusion regions. Such a memory cell is characterized in that a passivation film is formed on an interlayer insulation film insulating the floating gate and the bit lines from each other, and that a contaminant shut-off layer is provided between the passivation film and the floating gate. With this structure, the route carrying contaminants into the cell can be shut off even during manufacture thereof, achieving a high reliability of the product.

  • Patent number: 5545254
    Abstract: Calcium phosphate compositions that are particularly useful and unique as orthopedic and dental cements and remineralizers, as well as methods and kits for their use, and the resulting products are disclosed. The compositions comprise tetracalcium phosphate which has been prepared from a mixture with a calcium to phosphorous ratio of less than 2, or prepared and maintained under substantially anhydrous conditions prior to use or, preferably, both. The novel compositions are converted substantially to hydroxyapatite upon setting, are substantially gradually resorbable and replaced by bone when implanted in contact with living bony tissue, and offer distinct advantages in terms of cement strength, setting time and reliability and other properties.

  • Patent number: 5542568
    Abstract: The combination of zig zag folded tissue stack has separate portions of the tissue defined by lateral perforations. The tissue is a moisturized tissue and is retained in a special rectangular container with the free end of the tissue fitted through a slit which frictionally retains the tissue unless it is manually moved through the slit. The slit is fashioned in a manner which facilitates tearing of the portions of the tissue along the perforations after it is withdrawn through the slit. A cap for the slit is designed to keep the exposed portion of the tissue moist.

  • Patent number: 5544191
    Abstract: The improved metal vapor laser capable of cold operation performs plasma etching on a vaporizing metal within a laser tube in the presence of a reactive gas so that the metal is vaporized at temperatures below its boiling point to effect laser oscillation. The laser can be operated at much lower temperatures than a conventional hot-operating version which produces metal vapors by thermal evaporation; in addition, the laser will experience a smaller heat loss while undergoing limited thermal damage to its structural members; further, laser light can be oscillated to produce high output power and, at the same time, the warmup time can be shortened significantly.
