A process and apparatus for building a green tire. The process includes mounting a carcass, in the form of a cylinder, around a green tire building machine having left and right shoulder formers with radially expandable bead locking mechanisms. The left and the right shoulder formers are each moved together into an idle movable state where the shoulder formers are allowed to move freely in an axial direction either closer or farther from each other. The bead locking mechanisms are radially expanded so as to lock the beads in a set position on the outer circumferential surface of the carcass outside the respective bead locking mechanism. Once the beads are locked, each of the shoulder formers are placed in a driven movable state for driving the respective shoulder formers toward each other thereby narrowing the distance between the beads so as to shape the carcass into a toroidal form.

A case has parts storage openings through a top plane. Terminals protrude above the plane and extend downward through the case to a bottom plane, where they are bent to conform to the bottom plane. Interconnections of the terminals in the bottom plane provide the wiring pattern necessary for the creation of an LC filter. LC combination parts are made using a coil wound on a coil support with a capacitor secured to the top surface of the coil support. The coil part of the LC combination parts are inserted into the parts storage openings of the case, to secure the coils rigidly in place. The coils and capacitors are affixed to the terminals above the top plane. The resulting rigid support of the LC combination units provides stable and accurate filter characteristic in a compact package. The interconnections of the terminals in the bottom plane permits observation of the connections to permit manual inspection or the use of pattern recognition hardware and software for robotic sorting and assembly.

摘要:
An ultrasonic probe comprising an acoustic lens (20) having a concave lens surface (21) formed on one side of a lens body, and a piezoelectric transducer (23) disposed on the other side of the acoustic lens, ultrasonic waves generated by applying voltage to the piezoelectric transducer being focused through the lens surface to detect the reflected waves of the ultrasonic waves from a sample (26) by the piezoelectric transducer for obtaining information about the surface or interior of the sample. The lens surface (21) of the acoustic lens (20) is defined by an etch profile (15) formed by etching a substrate material (11) which makes up the lens body.

A liquid hydrocarbon such as a natural gas liquid generally contains a small amount of mercury in a state of elemental mercury, ionized mercury, ionizable mercury compounds, which are requested to be removed thoroughly. Further, organic mercury compounds are contained in some natural gas liquid and other liquid hydrocarbons depending on their district of production, and its removal is also necessary.Already known adsorbents can adsorb elemental mercury and organic mercury compounds in a liquid hydrocarbon, but they hardly adsorb ionizable mercury compounds and ionized mercury derived from the ionizable mercury compounds.According to the preesent invention which comprises contacting the liquid hydrocarbon with a sulfur compound represented by a general formula MM'S.sub.x, wherein M is selected from a group consisting of alkali metal and ammonium radical, M' is selected from a group consisting of alkali metal, ammonium radical and hydrogen an x is a number of at least 1, the sulfur compound and mercury in the liquid hydrocarbon reacts to form mercury sulfide which is insoluble in the liquid hydrocarbon to be separated therefrom.If the liquid hydrocarbon contains organic mercury compounds together with elemental mercury ionized mercury and ionizable mercury compounds, the above-mentioned process is to be combined with a process of contacting the liquid hydrocarbon with an adsorbent comprising heavy metal sulfide to adsorb the organic mercury compounds together with the mercury sulfide which is formed in the above-mentioned process.
