An apparatus for measuring the dynamic characteristics of the vehicle wheel alignment in non-contact fashion with high accuracy is disclosed. A laser light source (4) emits a laser beam of a predetermined geometric pattern toward the wheel side surface. A laser beam control device (6) controls the width of the laser beam in such a manner as to be radiated only in a predetermined range of the wheel side surface. Two laser light sources (120), (121) emit non-parallel laser beams. A photdetecting device (122) receives the two laser beams and converts them to two corresponding image data. A processing unit calculates the distance between the two images based on the two image data and calculates the wheel alignment based on the same distance.

A method for measuring the viscosity of a green compact sample includes the steps of finding a corrected value V′ of the sample volume of the green compact sample, where the corrected value V′ of the sample volume is a volume occupied by the inorganic powder in the green compact sample; finding a corrected value (dh/dt)′ of the sample deformation rate of the green compact sample, where the corrected value (dh/dt)′ of the sample deformation rate is the difference between the apparent sample deformation rate and the sample deformation rate due to sintering shrinkage; separating a temperature range X in which sintering shrinkage dominates and a temperature range Y in which plastic deformation dominates with respect to the displacement of the green compact sample; substituting the corrected value V′ of the sample volume for the sample volume V and substituting the corrected value (dh/dt)′ of the sample deformation rate for the sample deformation rate dh/dt in the Gent equation with respect to the temperature range X; and substituting the corrected value V′ of the sample volume for the sample volume V in the Gent equation with respect to the temperature range Y.

An X-ray computerized tomography (CT) apparatus including a cyclic movement detector to detect a cyclic movement of at least a part of a living body to be examined, and producing an output signal representing the cyclic movement, a rotational member support an X-ray source and an X-ray detector, and rotating around the living body, a driving mechanism to drive a rotation of the rotational member, and a control unit to control a rotational speed of the rotational member in accordance with the output signal indicative of the cyclic movement from the cyclic movement detector, so that the X-ray detector collects total scan data for reconstructing a single slice starting at a predetermined phase of a signal cycle of the cyclic movement of the part of the living body, and not ending until immediately before a corresponding phase of a next cycle of the cyclic movement.
摘要:
A charge-reducing film is used for coating a surface within a vacuum container containing electron-emitting devices to prevent deviations of electron beams caused by electric charges of the furface. The charge-reducing film comprises a nitrogen compound containing one or more than one transition metals and at least one element selected from aluminum, silicon and boron. An oxide layer may be arranged on the charge-reducing layer.

In an injection needle provided at the tip of an injector, the injection needle is provided with a properly rotatable operation member in front of a base thereof, an engagement member is fixed rearward on the outer periphery of the needle, a spring is provided in such a manner that the front of the needle is protruded toward the front end of the operation member while the engagement member pierces into the center of an axis of the base and the operation member and the engagement member is energized backward with respect to the base, and the engagement member is latched by the front of the base to hinder the retreat of the engagement member, and when the operation member is rotated with respect to the base from that state, the hindrance to retreat of the engagement member with respect to the base is released, to thereby deeply retreat the needle from the front end of the operation member.
摘要:
A dielectric ceramic composition which has a high dielectric constant and a high Q value, as well as excellent temperature stability, and which is sinterable at a relatively low temperature. The dielectric ceramic composition of the present invention is formed of a mixture of a BaO--TiO.sub.2 --REO.sub.3/2 --BiO.sub.3 ceramic composition wherein RE represents a rare earth element, and a glass composition. The glass composition contains about 13-50 wt. % SiO.sub.2, about 3-30 wt. % B.sub.2 O.sub.3, about 40-80 wt. % alkaline earth metal oxide and about 0.1-10 wt. % Li.sub.2 O.
