The invention relates to a folding structure provided with a lock structure for the folding leg stud, which is capable of releasing the respective locked state by pressing the lock lever being in almost the same standby position even when the leg stud is deployed or folded. In this folding structure, even when the lock device as described above is used, the leg stud is allowed for compact storage without taking much space and thus a highly reliable folding structure can be provided.

On a disc master DS, a record mark having a variable length according to the first data is formed at a displaced position to which the record mark is displaced, in a direction crossing the reading direction thereof, according to a wobble signal obtained by modulating the second data in a predetermined modulating method. A second start position at which the head of the second data is recorded is away from a first start position at which the head of the first data is recorded by a predetermined value.

Water-continuous emulsion of elastomeric polymers are disclosed having a solids content of greater than 75%, an average particle size less than 5 &mgr;m, and having sufficient stability to produce a stable lower solids emulsion upon dilution with water comprising; an elastomeric polymer, surfactant, water, optional plasticizer, optional low molecular weight acid, and is essentially free of organic solvents. The water-continuous emulsions of elastomeric polymers can be prepared by; (I) forming a premix that is essentially free of organic solvents comprising an elastomeric polymer and surfactant, and optionally a plasticizer and low molecular weight acid, and (II) adding water to the premix with mixing to form a water continuous emulsion of the elastomeric polymer having a solids content of greater than 75%, an average particle size less than 5 &mgr;m, and having sufficient stability to produce a stable lower solids emulsion upon dilution with water.

A method for producing a unitary toothed part with a shaft and the resulting products. In the process, a blank is formed. The blank includes a shaft part and a flange part. The flange part having a thicker outer diameter and a thinner inner diameter. The outer diameter is formed into a tubular part by drawing. A plurality of teeth and remnants are formed by extruding the tubular part. At least one spline is formed by extruding the shaft part. Through the steps of forming, drawing, and extruding, a blank is made into a unitary part having teeth and a shaft thus increasing precision, rigidity, durability, and reducing forming costs.

摘要:
A fluorescent display device capable of minimizing a variation in pitches between lead terminals and deformation thereof and attaining mounting of the device on a circuit board without soldering. The lead terminals each are bent at a distal end thereof so that the distal end is held in each of terminal holding holes of a mounting holder to hold the mounting holder therein, so that the fluorescent display device is mounted on the circuit board while keeping the mounting holder and circuit board fixed to each other through a fixing structure and keeping the lead terminals pressedly contacted with connections on the circuit board.
摘要:
An industrial and economical method for obtaining a (S)-3-halogeno-1,2-propanediol, which comprises cultivating a microorganism belonging to the genus. Pseudomonas which has an ability to assimilate (R)-3-halogeno-1,2-propanediol and can grow by assimilating (R)-3-halogeno-1,2-propanediol as a single carbon source, in a culture medium containing a racemic 3-halogeno-1,2-propanediol as a substrate, and isolating the (S)-3-halogeno-1,2-propanediol from the culture medium.
摘要:
An optical recording medium for accurately deriving the address information or the disc rotation control information despite narrow track pitch and for recording signals to a high density, and a method and apparatus for recording and/or reproducing such optical recording medium. The optical recording medium has a wobbled groove and pits formed at a pre-set interval in an area between turns of the wobbled groove. The recording/reproducing method includes controlling rotation of the optical recording medium by a wobbled signal from the groove and detecting the position on the optical recording medium of a recording signal by pit signals detected from the pits. The recording/reproducing apparatus includes a detection device for detecting the wobbled signal from the groove and a detection device for detecting pit signals from the pits. The rotation of the optical recording medium is controlled by the wobbled signals detected from the groove and the position on the optical recording medium of the recording signal is detected by the pit signal detected from the pits.
