Title: Optical fiber
Inventor: MUTA KENICHI
IPC: C03C13/04
Filed: 1996-09-12
Abstract: PROBLEM TO BE SOLVED: To obtain optical fiber having a wide band and a little transmission loss in a radiation environment by forming an optical fiber core essentially comprising quartz, containing Ge and having controlled distribution of refraction index and then incorporating a specified or more amt. of chlorine into the core. SOLUTION: In order to make a large amt. of chlorine remain in a glass, for example, a chlorine-based gas is added with a high density to an inert gas when the glass material is sintered (in a vitrification process). By this method, chlorine can be made to remain by at least 10wt.%. Therefore, defects induced by Ge can be suppressed by competitive reaction of Ge and chlorine to trap electrons. For example, the chlorine gas concn. during sintering is controlled to obtain the ratio with the inert gas satisfying He/Cl=9.1 to 10. Thus. an optical fiber having 1% difference in refractive indices and 50/125(μm) core diameter/outer diameter can be obtd. The optical fiber has 11wt.% chlorine density. <=3.0dB/km transmission loss for 0.85μm wavelength and >=400MHz transmission band. The increase in the loss under 1×10<4> rad accumulation of γ-rays is <=2.5dB/km.

Title: Shear-prestressed concrete floor slab composite part and its manufacture
Inventor: YAMAZAKI TAKEHIRO
IPC: E04G21/12
Filed: 1990-09-14
Abstract: PURPOSE:To reduce the number of dowels or stud dowels to be provided to joints by a method in which in producing a composite part formed by integrally joining concrete floor slab and beams, a shear prestress is introduced into joints longitudinally to relieve shearing stress caused by bending loads. CONSTITUTION:The position slightly lower than the upper edge on the joint face X side between a beam 1 and a floor slab 2 is continuously compressed by external force P, and the floor slab 2 is placed on it. A high-strength bolt B for joining the beam 1 and the slab 2 is clamped with nuts N to join them, the slab 2 is bent downwards to generate pressure stress 6 in the upper part and also to generate tensile stress T in the lower part. The force P is removed, the beam 1 and the slab 2 are straightly restored by leaving the stress C to some extent in the beam 1, and a corresponding stress T is generated in the floor slab 2 to impart a shear prestress along the joint face X. When a load is placed to the composite part of the beam 1 and the slab 2, shear stress to be newly generated by loading can thus be relieved.

Abstract: PROBLEM TO BE SOLVED: To conduct creeping and to wind a yarn on a taper-end package by providing a means for changing the distance between the rotation centers of a pair of traverse vanes. SOLUTION: Sliders 16 are moved in the separating direction (axial direction of a package P) between rotation centers O2, O3 by the exciting force applied to them together with timing belts 17 to increase the eccentric quantity ε between the rotation centers O2, O3. When a ball screw bolt 26 is rotated reversely, the sliders 16 are moved in the approaching direction between the rotation centers O2, O3 to decrease the eccentric quantity ε between the totation centers O2, O3. A traverse vane 4 is moved together with a traverse guide plate 2, and a traverse vane 5 is moved together with a traverse guide plate 3 to change a traverse width T.  The traverse width T is decreased when the eccentric quantity ε between the rotation centers O2, O3 of the traverse vanes 4, 5 is increased, and the traverse width T is increased when the eccentric quantity εis decreased to the contrary.

Title: Memory control priority system
Inventor: YAMADA WAHEI
IPC: G06F5/06
Filed: 1991-09-24
Abstract: PURPOSE:To surely carry out a major word access instruction by setting the priority of the access instruction at a level higher than a minor word access instruction in each fixed cycle. CONSTITUTION:The executing priority of a minor word access instruction is usually set higher than that of a major word access instruction and then the executing priority of the latter instruction is set higher than that of the former instruction in each fixed cycle by a periodical priority change control part 50. In other words, the minor word access instruction usually has the priority higher than the major word access instruction and also the latter instruction has the priority higher than that of the former instruction in each fixed cycle when the instructions are stored in a minor word buffer for the minor word access instruction and a major word buffer for the manor word access instruction respectively. Thus it is possible to quickly carry out the minor word access instruction requiring a high speed response and also to surely carry out the major word access instruction requiring not so high speed. In such a manner, the memory control performance is improved.
