Title: Floating gate storage device with control of dielectric thickness - uses oxide-nitride-oxide dielectric layer between two gates which overlaps in one direction to add capacitance
Inventor: CHOI JEONG-HYEOK
IPC: H01L21/8247
Filed: 1991-05-02
Abstract: The non-volatile storage device consists of a floating gate array (120) and peripheral logic (125) formed on a semiconductor substrate (70) with field-oxide regions (72). The array consists of multiple bit-lines and word-lines. A process flow is claimed with the following major steps: a first dielectric layer (74), pref. Si-oxide and pref. a tunnel-oxide layer for the storage cell, and first conductive layer, pref. polysilicon, are formed on the substrate. The conductive layer is pref. deposited by LPCVD and doped using POCl3. A photo resist layer is deposited and a pattern developed in which the gates are defined in the direction of the word-lines, but not in the direction of the bit-lines, at right angles to the word-lines. An Oxide-Nitride-Oxide composite dielectric layer (85) is formed on the surface and removed in the peripheral regions (125). A third dielectric layer is formed (92) and a second conductive layer (94) deposited, pref. polysi or a low resistance layer such as the silicide of W, Ti or Ta. A masking layer is formed to allow the floating gates and control gates to be formed. Using a second pattern the peripheral gates are etched. The composite dielectric layer is pref. formed by thermal oxidation to form the first oxide layer, LPCVD to form the nitride layer and thermal oxidn. of the nitride layer to form the second oxide layer, e.g. 20 mins. wet oxidation at 1000 deg.C. Also claimed are deposition methods for both oxide layers and a combined thermal and depsn. method for the upper oxide layer. Also claimed is the use of Ta2O5 instead of the nitride layer. USE/ADVANTAGE - The process allows the self alignment of floating gates and control gates in one dimension and the overlap of both in the other dimension with between them the same dielectric layer on the edge as on the top surface.

Title: Controlling quiescent power supply current test for CMOS circuits - applying test steps to stimulate circuit being tested with changeover operations releasing input signals when test set is completed
Inventor: KEMNITZ GUENTER
IPC: G01R31/30
Filed: 1991-05-28
Abstract: The input signals, for the time in which the operating current (IDD) of the CMOS circuit is greater than the max. permitted static operating current (IDDQ max) corresp. to a fault free circuit, are maintained constant.

A fault signal (ERR) is formed upon exceeding of the time specified for the working period of the test set as well as upon exceeding of a time specified for a test step. Circuitry for carrying out the method includes the CMOS circuit (1) consisting of the circuit (1.2) to be tested, a test pattern generator (1.2) connected to all the data inputs of the circuit to be tested and the test data evaluation circuit (1.3), a current threshold circuit (2) and a pulse divider (3). ADVANTAGE - Working time of test set reduced. Ensures that fault free circuit is continuously classified as such.

Title: Correcting undesirable human behavioural patterns - using combination of pulse rate and skin conductivity measuring appts. to ascertain basic sensitivity of individual reaction to external stimulus
Inventor: IANNONE VINCENZO PROF DR
IPC: A61M21/00
Filed: 1991-06-27
Abstract: The subject is subjected to both pleasant and irritating sounds and pictures to assess stress and tolerance thresholds to cure unwanted habits, e.g. nail-biting and bed wetting. Pulse and skin conductance measurements assess when an individua threshold is reached and allow the interchange between stressful and relaxing atmospheres, allowing the subject to feel, after a time, that he/she was overcome the subconscious behavioural problem. The relaxing experience can be provided by a tape recorder producing plesant sounds or music so that physical functions, e.g. blood pressure, muscle tone, peripheral temp. and metalsolic rate can be normalised.

Title: Tooth implant - has pt. with surface irregularities contg. hard outer pt. of jaw bone and pt. covered with biologically active material
Inventor: MOCHIDA MASAAKI
IPC: A61C8/00
Filed: 1991-09-17
Abstract: A tooth implant comprises (A) a part or region which comes into contact with cortical bones (Substantia corticalis sive compacta) which has surface irregularities and (B) a part which comes into contact with the Substantia spongiosa adjoining part (A) having a surface of a material which exhibits biological activity, whereby part (A) contacts the cortical bones of the jawbone when the implant is implanted in the jawbone and part (B) is situated such that it is in contact with the Substantia spongiosa of the jawbone.

Title: Operating control for milking parlour where cows have individual boxes - comprises automatic operation of access and exit gates in sequence until all boxes are occupied and process reversed after milking
Inventor: HAPPEL WERNER
IPC: A01K1/12
Filed: 1992-01-17
Abstract: Cows enter through central gates into a gangway one by one when all access gates to boxes are open. The leading animal can only pass into the first box because the open gate blocks the passageway. When it is inside the box the gate closes and the following animal can only enter the second box. This procedure is repeated until all the boxes are occupied and all gates closed, and the milking process is automatically set in motion. When milking is complete a signal is transmitted to open all exit gates and the first operation is then reversed allowing the animals to go out. ADVANTAGE - Obviates complicated manual application and congestion in the gangway.

This may be carried out as some forms of mixed yarn, or the mix may be in the difference between weft and warp, or the types of fibres bonded in the nonwoven. The mixt. of the high and low melt may be in the yarn as filament, a cord, or folded, or spun fibre. The fabric is then heated as it is pressed through a calender with heated rollers, with the required amt. of melt to leave air passages. In some cases this is equiv. to the use of microfibres. USE - To mfr. fabric suitable for passenger protection airbags, filtration cloth or geo-textiles. When the fabric is coated with plastic, it may be used for lorry sheeting, conveyor belting, or tyre mfr..

Abstract: Intervertebral disc endoprosthesis having two prosthesis plates (1, 2) to be connected with the end plates of the associated vertebral bodies, and a prosthetic core (3) interacting with at least one prosthesis plate via an articular surface (6) permitting a rotary movement about the upward axis. In order to permit a rotary movement about the upward axis (9) while at the same time opposing this movement with a resistance, the articular surface forms curvatures of different mean radius in the median section and in the frontal section. The radius of curvature in the sagittal section is expediently smaller than that in the frontal section. In order to avoid excessive twisting, stops may be provided on the prosthesis plates and the prosthesis core. These are designed, for example, as ribs and grooves extending in the median plane. <IMAGE>
