Title: Method for converting pixel value of digital image
Inventor: STEARNS CHARLES WILLIAM
IPC: A61B6/00
Filed: 1999-04-20
Abstract: PROBLEM TO BE SOLVED: To provide a method for converting a value indicating pixel strength from an input dynamic range to an output dynamic range. SOLUTION: In this method, the input dynamic range is decided by an acquisition circuit and the output range is decided by a device or a circuit element for display or output on the other hand. The histogram of an input value is formed and a lower limit value L in the useful part of the input range is selected from the histogram. Then, based on the histogram after logarithmic transformation using the original histogram and a threshold identified, based on the lower limit value, the upper limit H of the useful input range is decided. Then, by referring to the lower limit value and upper limit value, a pixel value is converted. By this method dispersion is compensated in utilizing the input dynamic range and the used input range is appropriately scaled to a utilizable output range.

IPC: H03M1/82
Filed: 1999-04-20
Abstract: PROBLEM TO BE SOLVED: To provide the DA converter which has high precision and is small in circuit scale. SOLUTION: This DA converter 100 is equipped with a speed pulse generation part 62 and a filter part 64. A digital signal 40 is inputted to a spread pulse signal generation part 62. The spread pulse signal generation part 62 generates a spread pulse signal 44 which is spread in time series with temporal pulse density specified with the digital signal 40. The spread pulse signal 44 is composed of pulses having the same pulse width and amplitude. The filter part 64 smooths the spread pulse signal 44 and outputs an analog signal 50. The spread pulse signal 44 is spread in time series in specific cycles, so no ripple of low frequency is generated. The filter part 64 may, therefore, have a high cutoff frequency and need not have complicated circuit constitution like a higher-order filter part. The cutoff frequency of the filter part 64 is set high to shorten the settling time of the DA converter 100.

IPC: G01J3/02
Filed: 1983-06-22
Abstract: PURPOSE:To achieve a higher analysis sensitivity by orienting an expanded graphite, thermally decomposed carbon or graphite in a layer on the surface contacting an assay sample of a crucible for atomic absorption analysis mainly composed of expanded graphite to prevent the permeation of the assay sample into pores of the graphite. CONSTITUTION:A powder of natural graphite, kish graphite or the like is oxidized to form an intergraphite compound. Then, interlamellar compounds are removed by washing and undergoes a thermal treatment or the like in an oxidizing atmosphere to obtain an expanded graphite, which is used as intact or to which a binder such as tar pitch is added and kneaded as mixture. Then, it is crushed and undergoes an extrusion molding to form a cylindrical material in which the expanded graphite is oriented in a layer with no square pore on the surface thereof. Then, a horizontal cylinder crucible is cut out thereof. When the expanded graphite undergoes a compression molding, vertical pores are liable to be left on the surface at the right angle to the direction of compression and hence, a hydrocarbon gas, halogenated hydrocarbon gas or the like is passed through it in a kiln of an inert gas atmosphere to settle the thermally decomposed carbon or the thermally decomposed graphite in a layer on the surface thereof thereby eliminating vertical pores.

Abstract: PURPOSE:To enable to properly suppress the rolling of a car body during the running of an automobile at all times in response to various conditions such as the total weight, running speed, lateral acceleration at turning and the like by controlling the length of stabilizer arms. CONSTITUTION:When the truck is loaded heavily or turned with a large curvature, only a discharge side solenoid valve 34 is released by an electric signal from a controller 37 and consequently the compressed airs in cylinder chambers 46 and 47 are discharged to the open air, resulting in contracting fixed stabilizer arms 16 and 17 into arm parts 12 and 13 by means of return springs 35 and 36 so as to shift a movable stabilizer bar 11 to a rear axle 42 side in elongated holes 22 and 23 in order to shorten the length of arms 18 and 19. Consequently, because the twisting angle of the bar 11 after the length of the arms 18 and 19 are shortened in respect to a certain displacement of the axle 42 side becomes larger than that of the bar 11 before the length of the arms 18 and 19 are shortened, a larger rolling rigidity is realized, resulting in reducing the rolling of the truck body and consequently improving the running stability.
