Title: Optical module
Inventor: KOREEDA YUICHI
IPC: G02B6/42
Filed: 1998-03-30
Abstract: PROBLEM TO BE SOLVED: To enable fitting in spite of a little deviation in the center axis of a bare optical fiber and the guide groove of a receptacle and also to improve a reliability and a workability on an optical module by fixing the bare optical fiber fixed to a housing to the receptacle by means of a rotary operation and inducing the bare optical fiber to the guide groove of the receptacle with a taper-shaped inclining guide groove. SOLUTION: When the housing 4 and the receptacle 2 are mutually connected, the housing 4 is constituted so as to execute a rotary operation with one end part 71 of a base part 7 as a center. Then, the bare optical fiber 31 is gradually made to approach the base part 7 of the receptacle 2 in an inclining state and the taper-shaped inclining guide groove 9 communicating with the guide groove 8 is formed on the upper surface of one end part 71 of the bas part 7 being a place where the optical fiber enters in the guide groove. Thus, the fiber 31 is easily guided by the guide groove 8 and is not destroyed in spite of a little deviation in the correlative position between the fiber 3 and the groove 8.

Abstract: PROBLEM TO BE SOLVED: To mold a substrate while utilizing the deformation repulsive force of a viscoelastic body and to uniformize transfer property, double refractivity and thickness by providing the viscoelastic body whose thickness is changed in accordance with the position of a cavity on the back surface of a cavity core. SOLUTION: A viscoelastic plastic material 13 is provided on the back surface of the cavity core of a movable side shape 3 of a molding metallic mold and the thickness is varied so that it becomes thicker as it moves from the center section of the substrate to the outer peripheral section. Let t1 and t0 be the thicknesses of the material 13 at the inner and outer peripheral section, Δδbe the difference in the substrate thickness at the inner and the outer peripheral sections, Δp be the molding pressure difference of the inner and outer peripheral sections, E is the elastic modulus of the material 13 and t0 is obtained from t0 =ti +Δδ.E/Δp where ti satisfies ti <=S.(E/Δp).tc and a molding shrinkage ratio S in the substrate thickness direction is set approximately 1% and tc is the thickness of the cavity.  Thus, the thickness of the substrate is molded with an approximately uniform thickness, the pressure value is reduced and the substrate double refractivity is kept at a low level.

Title: Method and device for floating air
Inventor: ALBERT KEVIN FRANCIS
IPC: B65H45/22
Filed: 1999-03-26
Abstract: PROBLEM TO BE SOLVED: To use a device so as to form folding edge on a web without causing remarkable contact between a former and the web by providing an air supply forming means with at least one slot formed along at least enough length of a first surface. SOLUTION: A front plate 308 extended downward so as to cover a forming bar is assembled. The use of each air hole in the circumferential area of the forming bar is excluded. Instead of using the each air hole in the circumferential area, it is formed as a sandwich-like structure, and in this case, air is led to flow out from at least one slot 310. On a side opposite to the front plate 308, the same slot is formed between the front plate 308 and the other forming bar 316. Thus, a low pressure area produced between air holes arranged in the conventional former and a low pressure area produced in the air hole of the conventional former can be excluded.

Title: Nuclear fuel element
Inventor: HIRUDEINGU MOGAADO
IPC: G21C3/17
Filed: 1994-04-22
Abstract: PURPOSE: To reduce the secondary breakage by generation of hydrogenated blister by a fuel coating defect, and reduce emission of radioactivity and generation of fission energy by arranging a neutron absorber formed of sponge-like boron oxide on the outside of an energy generating part. CONSTITUTION: When water is penetrated by the defect of a covering pipe 1, it reaches the plenum space 14 of a fuel element, and makes contact with a neutron absorber 16. By the chemical reactivity and moisture absorptivity of boron oxide contained in the absorber 16, a reaction produce containing boron is dissolved, evaporated, mixed with water in the covering pipe 1, and gradually moved to all positions of the fuel element through the fuel element, or through an axially extending groove. The fission is lowered by the movement of the boric acid containing material to reduce the energy generating quantity. Since the generation of hydrogenated blister in the covering pipe 1 is suppressed to reduce the danger of axial crack, it is not required to throttle the output of a reactor. Thus, a defective nuclear fuel element can be used over a longer period.

Abstract: PURPOSE:To secure the incipient performance of a device with no accumulator by providing a relief valve for an oil flow way between the hydraulic pressure chambers of a master cylinder and the delivery port of a hydraulic pump wherein the relief valve is opened when braking hydraulic pressure exceeds pressure equal to or more than a specified one. CONSTITUTION:A relief valve 22 is provided for an oil flow way 21 which connects hydraulic pressure chambers 5 and 6 of a master cylinder 1 with the delivery side of a hydraulic pump 23. When braking hydraulic pressure in the oil flow way 21 exceeds specified one set by a spring 22f, a piston 22a is moved to the right, a ball valve 22c being separated from a valve seat by a rod 22d, braking hydraulic pressure being released to a reservoir 11, and abnormal increase in pressure is thereby prevented. At this time, as the actuator 70d of a switch 70 is pushed by the right end of the piston 22a, the switch is turned off so that a motor 71 driving the hydraulic pump 23 is thereby suspended. By this constitution, the incipient performance of a device can be secured with no accumulator.
