Title: Fuel injection device for internal combustion engine
Inventor: YAMAMOTO KAZUO
IPC: F02M67/02
Filed: 1990-09-14
Abstract: PURPOSE:To prevent compressed air containing moisture from entering into a driving part housing by providing a split member for preventing the compressed air from entering into the driving part housing through a clearance between a needle insertion hole and a needle. CONSTITUTION:Since compressed air compressed by atmospheric pressure contains saturated steam, a lip type packing 102 is provided to prevent the compressed air from entering into a driving part housing 27 from between the wall surface of a needle insertion hole 22 and a needle 25. This lip type packing 102 is a ring member formed of flexible material such as oil-resistant synthetic rubber, and provided with lip parts 102a, 102b to be brought into contact with the surface of the needle 25 and a body 21 so as to hold them airtightly. Since the compressed air is filled on the lower side of the lip type packing 102, the lip parts 102a, 102b are respectively pressed/adhered to the side face of the needle 25 and the wall surface of a ring groove 101 so as to hold desirable seal at these parts.

Title: Coated optical fiber
Inventor: TANAKA KAZUNORI
IPC: G02B6/44
Filed: 1999-08-30
Abstract: PROBLEM TO BE SOLVED: To prevent strength of an optical fiber from being deteriorated in a deteriorative environment under no stress by forming plural coated layers consisting of an ultraviolet ray-curing resin around a glass fiber based on quartz glass and specifying the pH and the turbidity of the resin of at least the lowermost layer of the coated layers. SOLUTION: The coated optical fiber 4 is obtained by forming two or more coated layers, first and second layers 2, 3, consisting of the ultraviolet ray-curing resin around the glass fiber 1 based on quartz glass. The ultraviolet ray-curing resin of at least the first coated layer 2 is made to have 8.0 or lower pH and 0.2 or higher turbidity. The pH and turbidity are adjusted, for example in the case of urethane-acrylate resin, by the selection of material kinds of the component materials and by adjusting the mixing amount of alkaline materials such as amine additives and other materials having polar groups. When the resin of the layer 2 has such pH and turbidity, the fiber 1 in high temperature water under no stress is prevented from being deteriorated and has around 90% or higher breaking strength holding rate.  When the resin of the second coated layer 3 has also the similar pH and turbidity, the breaking strength holding rate can be made into almost 100%.

Title: Synchrotron and exposing method using synchrotron
Inventor: KAMON KAZUYA
IPC: G21K5/02
Filed: 1988-09-28
Abstract: PURPOSE:To converge or diverge the radiation light and expand the exposure field by controlling the orbits of electrons in a synchrotron with an electromagnetic lens. CONSTITUTION:When an electron beam passes an electromagnetic lens 8 installed in the middle of electron orbits 9, it is converged. When the beam passes a bending magnet 2, the electron orbits are bent, and at the same time the braking radiation is performed in the tangent direction of motion. This braking radiation generates the radiation light in the tangent direction of the converging motion of the electron beam 9, thus the radiation light obtained on a beam line 10 becomes the convergent light. The electron beam 9 having been radiated is focused at a focal point 11 after passing the bending magnet 2. The diverged electron beam 9 is again converged by the electromagnetic lens 8, and the beam is continuously radiated. On the other hand, the radiation light 4 is diverged in the vertical direction after being vertically focused at a focal point 7. The radiation light is converged or diverged, and the exposure field can be expanded.

Title: Reaction relaxation method of powder material for cured body of calcium phosphate and production of cured body of calcium phosphate
Inventor: SHIGENO KEIKO
IPC: A61L27/00
Filed: 1992-09-11
Abstract: PURPOSE:To control the reactivity of the powder material with a simple operation by treating the powder material for the cured body of calcium phosphate contg. one kind of alpha-tricalcium phosphate or tetracalcium phosphate with high- temp. and high-pressure steam. CONSTITUTION:The powder material to be used contains the alpha-tricalcium phosphate or tetracalcium phosphate or the mixture composed thereof as an essential component and may further contain hydroxy apatite or beta-tricalcium phosphate in some cases and preferably contains the alpha-tricalcium phosphate and/or the tetracalcium phosphate at >=1/3 of the entire part. The compsn. is not sufficiently cured if the content of these components is <1/3 of the entire part of the powder material. The treatment with the high-temp. and high-pressure steam is preferably executed under the conditions of 1 to 60 minutes at 100 deg.C (0.1kg/cm<2>) to 140 deg.C (2.7kg/cm<2>). The long-time treatment is needed to exhibit the effect if the temp. is below 100 deg.C. The effect is remarkable but the simple treatment is difficult if the temp. exceeds 140 deg.C.

Abstract: PURPOSE:To provide a core mold having chamfering parts provided to the corner parts thereof and having a hollow part for molding concrete block, easy in assembling and demolding operations and not having a gap permitting concrete refuse to penetrate into a molding surface or leaving a mark on the surface of the block. CONSTITUTION:The molding surfaces of the chamfering parts 3 of the corner parts of a core mold 1 are formed from inwardly protruding spring plates 4 to which a bowed bending habit is imparted and expansion devices 17, 18 stretching the spring plates 4 to a planar state are provided in the core mold 1. When the expansion devices 17, 18 are stretched, the spring plates 4 are stretched to a planar state to be expanded in substantial width to expand the core mold 1. At the time of demolding, the expansion devices 17, 18 are contracted to inwardly bend the spring plates 4 in a bowed state by the elastic forces themselves and the substantial widths of the spring plates 4 become narrow and, therefore, surface plates 2 retreat from the molding surface of a concrete block to generate gaps 26 to extract the core mold 1 in its axial direction.

Title: Roller conveyor
Inventor: USUI MOTOSUKE
IPC: B65G13/071
Filed: 1986-10-15
Abstract: PURPOSE:To sharply reduce vibrations in a conveyed work at times of conveyance and stoppage, by supporting a roller rotatively conveying the work to a small diametral part of a driving pulley, free of slide motion and rotation. CONSTITUTION:When a pair of pulleys are rotated with a motor driven, each driving pulley 8 is rotated by a belt 24. At this time, the roller 11 supported by a small diametral part 10 free of slide motion and rotation is also rotated together with these driving pulleys 8 in the same direction. When a conveyed work A is fed to and mounted on each roller 11 being opposed to each other, the conveyed work A is smoothly moved by friction between the underside and an outer circumferential surface 11a of each roller 11. Thus, since a shaft 6 rotating these driving pulleys 8 is locked to a support frame 2, even if there are somewhat variations in eccentricity, bending, etc., in the shaft 6 itself, a positional relationship between the underside of the conveyed work A and each roller 11 is not altered, so that vibrations are sharply reducible.
