摘要:
A volume data encoder with high encoding efficiency is provided. The object of the coding is volume data which contains a plurality of tomogram planes output from a CT and an MRI. A header analysis unit separates each plane image into header information and pixel information. A header compression unit compresses the separated header information. On the other hand, a two-dimensional transform unit conducts frequency decomposition on the pixel information. A skip portion detection and table generation unit detects skip portions that are the same in all coefficients in a z-direction, and stores them in a table. A one-dimensional transform unit conducts one-dimensional transform on the pixel information for coefficients except the skip portions. A unit block division unit divides each subband into unit blocks. An entropy encoding unit determines a parameter for entropy encoding according to statistical properties of all coefficients in all unit blocks included in each class.

An ultrasonic vibration apparatus includes a casing having a vibration face, a piezoelectric element mounted in the casing, and a disk-like vibration plate supported at a position along a concentric circle differentiating two regions, an inner region and an outer region. In the ultrasonic vibration apparatus, the disk-like vibration plate is constructed so as to be a part of the casing serving as the vibration face, and, the piezoelectric element is mounted in the central part of the disk-like vibration plate, thereby causing the inner region and the outer region to vibrate in substantially the same phase.

A rubber-steel cord composite comprising a steel cord having, in a planar image of the steel cord formed by X-rays passing through the steel cord, a fraction R of the total area occupied by filaments of from 0.45 or more to 0.95 or less in an arbitrarily selected portion of the steel cord having a length of 15 mm in an axial direction of the cord, is provided. The length of 15 mm in an axial direction of the cord means a length of 15 mm in an axial direction of an actual cord and the fraction R of the total area occupied by the filaments is expressed as R=F/A, wherein A represents the total area of the cord and F represents the area of the cord occupied by the filaments. An object of the present invention is to provide a pneumatic tire for passenger cars that shows no separation of the interface of adhesion during use, particularly during use in the run-flat condition, and exhibits excellent durability.

摘要:
A method and apparatus for controlling a continuously variable transmission of a motor vehicle includes a controller that controls the speed ratio of the continuously variable transmission in accordance with a predetermined shift condition. The method and apparatus perform shift control in a specific manner during an operation of an anti-lock brake system, for example, by smoothing at least one of the rotational speed of the input shaft and the rotational speed of the output shaft, reducing a rate of change in the speed ratio during down shifting, restricting upshifting of the CVT, increasing an amount of hydraulic oil delivered from an oil pump, and/or increasing belt clamping force.
摘要:
There is disclosed a safety pneumatic tire comprising a tire shell which is equipped with a toroidal carcass extending over a pair of bead portions and also functioning as a reinforcing material for a side wall portion connected to the bead portions and further for a tread portion, and which has a side-reinforcing layer on the internal surface of the side-wall portion; a rim which hermetically seals and supports the bead portions of the tire shell; and closed cell-based elastic foam which is filled in the internal hollow portion encompassed by the tire shell and the rim, wherein the constructional material of the elastic foam is butyl rubber or halogenated butyl rubber. The above safety pneumatic tire is markedly improved in run-flat durability, can reconcile favorable riding comfort chacteristic with the run-flat durability, is minimized in adverse influence upon the tire performances such as rolling resistance, and enables the production of a lightweight pneumatic tire.
摘要:
A heat resistant pneumatic tire whose tread is composed of a rubber composition comprising, as a main rubber component, a modified, conjugated diene based polymer prepared by adding an .alpha., .beta.-unsaturated carboxylic acid represented by the following general formula: ##STR1## wherein R.sub.1, R.sub.2 and R.sub.3 independently represent hydrogen atom, halogen atom, or an alkyl, alkenyl or allyl group having at most 5 carbon atoms, or a substituted alkyl, alkenyl or allyl group,to a conjugated diene based polymer in an amount within the range between 0.1% and 5.0% based on the weight of the conjugated diene based polymer. This tire is suitable for continuous running at high temperatures and maintains a good road-surface-grip performance even during such running.
摘要:
A body fluid excretion volume measurement apparatus for medical application. The apparatus stores body fluid excreted from patients in a body fluid storage tank and measures the resistance value with a resistance sensor. The resistance value depends on the shape of the body fluid storage tank, and if the tank is columnar, the resistance value is monotonically increasing with respect to the depth of body fluid. The output of the resistance sensor is processed by a measurement part and electric measurement of the body fluid volume stored in the body fluid storage tank is performed automatically.

A MOS transistor includes a gate electrode layer formed on an insulation layer which is formed on an element formation region defined by a field insulation layer formed on a P-type semiconductor substrate. The gate electrode layer has first and second openings formed therein. Further, N-type impurity diffusion regions acting as the drain and source of the MOS transistor are formed in those portions of the surface area of the semiconductor substrate which lie under the first and second openings.
摘要:
A delay circuit delays an input signal having a predetermined frequency by a time corresponding to a control signal. A delay amount detector detects a signal delay amount of the delay circuit. A charge pump circuit generates a DC voltage corresponding to a pulse width ratio between the input signal and a detection signal of the delay amount detector. This DC voltage is fed back to the delay circuit as a control signal.
