Patent EP-0361504-A2 (EP)
Inventor: KOSAKA TOKIHIRO
IPC: G01N33/49
Filed: 1989-09-29
Abstract: A particle suspension is irradiated with a laser beam (12) and scattered light from a single particle irradiated in an irradiating zone is detected as a plurality of particle signals. The laser beam (12) in the irradiating zone is formed to be narrower than the diameter of a particle nucleus in the direction of particle flow and wider than the diameter of the particle in a direction perpendicular to the particle flow. The degree of complexity of the particle nucleus is determined from high-frequency signal components contained in one type of particle signal based on side-scattered light (26) from one particle, and the degree of symmetry of the particle nucleus is determined from the magnitude of a difference between two types of particle signals based on side-scattered light (26) from one particle. The degrees of complexity and symmetry of the particle nucleus serve as data for particle analysis.

Abstract: An identity card, e.g. a cheque card or credit card, usually has a space in which the card user writes his signature when the card is issued. A weak point, as far as manipulations of the cards are concerned, has long been that the signature space could be eliminated and replaced by a counterfeit signature space. According to the invention, in order that such manipulations are easily recognisable and forgeries are consequently made more difficult, the security typography (guilloche print) which anyway covers the area surrounding the signature space is extended on without transition over the signature space also. If the counterfeiting of a signature space provided with such security typography is itself extremely difficult, it is practically impossible to arrange the security typography in such a manner that it passes continuously from the signature space into the area surrounding the signature space. <IMAGE>

Abstract: A balloon dilatation catheter (14) is provided with a fluted balloon (20) defining at least three wings (46). When the balloon collapses, it tends to assume the fluted configuration which defines a lower profile better adapted to pass through narrow channels, such as in endoscopes and guide catheters. The balloon is formed from a polymeric material in a method that involves the steps of tensioning the balloon to cause it to form flutes (44) while maintaining its interior under vacuum and subjecting the balloon, while so held, to heat and, thereafter, cooling the balloon while maintaining it in its tensioned, fluted configuration.

Abstract: A method for performing floating point division to produce a quotient having a mantissa of n bits as well as apparatus for performing the method is based on accessing an initial guess of a reciprocal of the divisor from a table of divisor reciprocals, computing an initial estimate the quotient in a corresponding estimate from the initial estimate of the reciprocal, increasing the precision of the mantissa of the reciprocal estimate, quotient estimate, and remainder estimate by computing an error parameter and iteratively computing a current reciprocal estimate, a current quotient estimate and a current remainder estimate from the error parameter and the latest reciprocal estimate, quotient estimate and remainder estimates. Also, the step of increasing the precision is repeated until the quotient estimate and reciprocal estimate exceed n bits. Lastly, the final quotient is computed from the last current quotient estimate plus the last current reciprocal estimate times the last current remainder estimate. In this way, a quotient result is generated that is correctly rounded without conditionally testing the magnitude of the quotient.

Filed: 1990-06-18
Abstract: In the CMOS circuit according to the invention, the latch-up sensitivity to output level (VOUT) disturbances which inject minority carriers (14) into the semiconductor substrate (1) is reduced by siting a third MOS transistor in the semiconductor substrate (1) with its gate (31) at a supply potential and its source (5) at the output potential between the two complementary transistors. This third transistor has a doped region which acts as a drain (30) and which is at a different supply potential. This region removes the minority injected carriers (14) from the semiconductor substrate (1) since, depending on the magnitude of the disturbance at the output (VOUT), the third transistor acts either as a common-base bipolar transistor with high current gain, the base being formed by the semiconductor substrate (1), or as a common-gate MOS transistor.

Abstract: Accurate control of the lateral position and spacing of a photosensitive medium (2) is provided for recording a succession of lines representing graphic images or portions thereof, without mechanical edge guides. The apparatus includes an optical edge detector (14), a film drive assembly having two independently controlled feed units (10; 12), and a deviation correction means to correct the position prior to actual printing of images. Preferably, a triang­ulation method is used to electronically correct the drive path of the medium (2). Error-correction is obtained by the combined action of the two independent feed units (10; 12) operated by an electronic control circuit receiving signals generated by the optical edge detector. The apparatus also includes means (35-37) to maintain the image receiving section of the photo­sensitive medium (2) in a flat plane. An image placement carriage (200) carrying optical elements (202) is supported on magnetic slider pads (211-213) forming bearing elements which hold the carriage onto smooth tracks (208) made of magnetic material, thus minimizing or eleminating vibrations from the motion of the carriage and improving the quality of the images formed on the photosensitive medium (2).
