Patent GB-968844-A (GB)
IPC: G01L1/08
Abstract: 968,844. Potentiometric voltage measurement; force measurement. MERESTECHNIKAI KOZPONTI KUTATO LABORATORIUM. Sept. 28, 1960 [Sept. 30,1959], No. 33319/60. Headings GIN and G1U. In an automatically balanced potentiometric system for measuring electrical signals derived from physical values such as force, weight, pressure, pH on thermocouple output, the rebalancing signal is obtained from a deformation-sensitive variable-impedance element mounted on a resilient member which is deformed by a servomotur energized by a difference signal obtained by comparing the signal to be measured with the rebalancing signal. The variable-impedance element may be resistive, inductive, capacitive, piezo-electric, magneto-resistive or photo-electric. In Fig. 1 the physical value to be measured is applied to a load cell M Z comprising an A. C. resistance straingauge bridge MB to give a corresponding electrical signal between terminals 11 and 13. This is applied to an amplifier 24 in series with the rebalancing signal obtained from a further straingauge bridge KB. Any difference signal energizes a servomotor 26 which rotates a cam 27 and an indicator 28, the cam deforming a resilient member 5 to which are attached the strain-gauges of the bridge KB. The deformation continues until the outputs of the two bridges are equal and the difference signal falls to zero. The resilient member 5 may be a cantilever beam (Figs. 2 and 3, not shown), a beam supported at each end and deformed in the middle (Figs. 4 and 5, not shown), a U-shaped member loaded across the tips of the U with strain gauges at the centre (Fig. 6, not shown) or a ring deformed across one diameter with strain gauges at the end of the opposite liameter (Fig. 7, not shown). The cam (or equivalent screw or sliding weight) can be shaped to provide any desired relationship between the difference signal and the output of the bridge KB, e.g. linear, quadratic, logarithmic or exponential. The bridges MB and KB are preferably maintained at the same temperature, to avoid errors due to variation in Young's modulus of the materials. Compensation for errors due to creep of the strainsensitive elements is achieved by choosing the resilient members in the two bridges to deform to the same extent or in a definite ratio to one another. The bridge KB may be replaced by a potentiometric circuit. For measurements of voltage instead of impedance, transformer winding 17 is omitted. The indicator 28 may provide a permanent record of the readings. The load cell MZ may be remote from the other part of the apparatus. The source voltage may be D.C. instead of A.C.

Title: Forming DRAM cells
Inventor: SUN SHIH-WEI
IPC: H01L21/3205
Filed: 1997-04-17
Abstract: A method of forming a DRAM includes forming a transfer FET on a substrate 50, the FET having a gate 56 on a gate oxide layer 54 above the substrate and a first and second source/drain region 82, 84 in the substrate on either side of a channel region under the gate. A silicon nitride etch stop layer 90 is deposited over the entire structure and then a thick layer of oxide 96 is deposited on the device. Chemical mechanical polishing is performed to provide a planar surface on the thick oxide layer. An opening is formed through the thick layer of oxide above the first source/drain region, stopping at the etch stop layer. The etch stop layer is removed within the opening in the thick layer of oxide. A capacitor electrode 98 is then formed in contact with the exposed portion of the first source/drain region 84. A similar self-aligned method can be used to form the bit line contact 112 for the device using the etch stop layer as a stop for the bit line contact etch.

Title: Image resolution conversion
Inventor: TAMURA YOUICHI
IPC: H04N7/01
Filed: 1998-05-19
Abstract: An input image having varying resolutions is converted to an output image having varying resolutions, using only a single circuit. A common-coordinate system common to the input image and the output image is generated by relating the number of pixels of the input image to the number of pixels of the output image. An absolute-coordinate of the pixel of the input image and the pixel of the output image is calculated and a pixel value of the output image is calculated from the values of corresponding pixels of the input image using the absolute-coordinates of the output image. A vertical common multiple and horizontal common multiple technique allow integral expression of how far an arbitrary line/dot of the matrix display device is from each of the lines/dots of the input image signals. Using linear interpolation, it is possible to display input image signals having varying resolutions on a matrix display device having a fixed resolution, without lacking pixel information which should be displayed on the matrix display device and further to display the input images scaled up and down on the matrix display device.

Title: Light shielding for lcd driver
Inventor: GOMI MIKA
IPC: G09F9/00
Filed: 1998-05-21
Abstract: A bare chip type liquid crystal driver is surely shielded to absorb light which reaches it without housing it in a package so that erroneous display due to the photoelectric effect can be prevented. A light shielding tape (109) is affixed to a surface of an upper panel (101) of a liquid crystal display panel (10) at an area which is opposite to the mounting area of a liquid crystal driver (107) mounted on the bottom surface of the upper panel (101). The light shielding tape (109) serves to shield the outer light incident on the liquid crystal driver (107). A diffusion sheet (40) composed of a light diffusing area (401) and a light absorbing area (402) located on the outer periphery thereof is arranged below the liquid display panel (10). The light diffusing area (401) serves to diffuse illumination light from a light source (202) to the liquid crystal display panel (10), and the light absorbing area (402) serves to absorb the extraneous light (C) incident on the liquid crystal driver (107).

Title: Method and apparatus for monitoring bubbles in a liquid
Inventor: RUSSELL STEPHEN LINDSAY
IPC: G01N21/53
Filed: 1999-04-29
Abstract: A method of monitoring gas bubble see and number concentration in a moving liquid medium 9 comprises directing a first light beam into a first defined volume 4 of the medium 9, and detecting the light emerging to produce a first output signal including fluctuations resulting from the presence of bubbles 10. The method may be refined to exclude fluctuations caused by solid particles by removing the bubbles and then conducting a second measurement, subtracting the results of the second measurement from the first. This method can have applications in non-continuous monitoring for process optimisation and in continuous monitoring for controlling the process in real time. The process may be an aqueous treatment process such as a "dissolved air flotation" process, for example.

Title: A tomography controlled radio-active ray irradiating apparatus
Inventor: KIMURA MASAKAZU
IPC: A61L2/08
Filed: 1999-09-14
Abstract: In projecting radioactive rays for sanitizing food or the like, an irradiating condition which attains a uniform dose of radioactive rays for the entire objects to be exposed is automatically determined. An X-ray CT unit 6 captures a sectional image of an object to be exposed 2, and an irradiating condition determining section 8 acquires the density distribution of the object to be exposed 2 based on the captured sectional image. The irradiating condition determining section 8 then searches for a particular irradiating condition under which the dose distribution of the radioactive rays in the object to be exposed 2 falls within a predetermined range. An irradiation controlling section 16 controls a radioactive ray irradiating unit 14 based on the irradiating condition, and projects radioactive rays to the object to be exposed 2 in accordance with the irradiation condition when the object is transported to the radioactive ray irradiating unit 14 by a belt conveyor.
