Title: Production of coated optical fiber
Inventor: SAKAMOTO MITSUHIRO
IPC: G02B6/44
Filed: 1988-11-28
Abstract: PURPOSE:To decrease the strain by the shrinkage on curing which the optical fiber on the outermost side receives and to obtain stable characteristics by setting the tension on the optical fiber on the outermost side among plural pieces of the optical fibers larger than the tension on the optical fibers on the inner side and arraying the optical fibers. CONSTITUTION:The optical fibers 1 which are coated with a UV curing type resin and are wound on plural bobbins 6 are drawn out and are arrayed to a flat shape under the tension kept applied thereon and are introduced into a tank 7 for application of the UV curing type resin by which the fibers are coated integrally with the resin. The fibers are then passed through a nipple and die part 8 and are molded to a prescribed shape and size; thereafter, the resin is cured by a UV ray irradiation furnace 9. The tension T1 to be applied on the optical fiber on the outermost side is then set at T1>T2 with respect to the tension T2 of the fibers on the inner side. The difference in the strain quantity after curing of the resin with which the fibers are integrally coated is eliminated in this way and, therefore, the transmission characteristics are stabilized.

Abstract: PROBLEM TO BE SOLVED: To control the temp. of the commodity reserve environment and the elapsed time at the same time by providing a plurality of temp. indicating members which differ in temp. and time characteristics to measure the respective coloring concns. and compute. SOLUTION: On a temp. indicating member print area 4 of a label-like temp. control member 1, e.g. three kinds of temp. indicating members 5 (α, β, γ) are printed.

Title: Light displacement sensor
Inventor: HOSOKAWA HAYAMI
IPC: G01S17/02
Filed: 1986-12-19
Abstract: PURPOSE:To measure displacement regardless of surface conditions, rough or mirror finished, by arranging a sensor head to make emission light incident slantly on the surface of an object while the reflected light from the object is returned to the sensor head as signal light. CONSTITUTION:A part of a laser light transmitted through an optical fiber 2 from a laser light source is reflected on an Au deposited film 4 and returned into the optical fiber 2 as reference light. The remaining part of the laser light is emitted from a head 1 to irradiate the surface of an object S at an angle thetaof incidence and reflected on the surface thereof toward an Al deposited mirror 5. The light reflected on the mirror 5 is reflected again on the surface of the object S following the same optical path and returns to the head 1 as signal light. The signal light and the said reference light interfere with each other when returning through the optical fiber 2. Then, variation of the signal light in terms of the optical path length is measured from changes in the intensity of the resulting interference light. In this case, the larger the angle theta of incidence, the higher the mirror surface reflection efficiency. This enables the inspection of the surface of a part machined, for instance.

Title: Transformer device
Inventor: KAGOHARA YOSHIJI
IPC: H01L23/473
Filed: 1995-10-25
Abstract: PROBLEM TO BE SOLVED: To effectively dissipate heat generated from the side of a transformer coil and reduce the noise level of a cooling fan by providing a cooling unit with a heat transport element and a heat sink and arranging a cooling fan at an air suction side of a heat sink. SOLUTION: A transformer coil 6 generates heat by energization and the temperature rises. The heat is transmitted to an insulating oil 3 and the temperature rises. Heat transmitted to the insulation oil 3 is transfered to a heat sink 2 from a heat transfer element 1 by natural convection of the oil 3 and is dissipated naturally by the heat sink 2. At the same time, since air is supplied from an air suction side of the heat sink 2 by rotation of the cooling fan 4 and the heat sink 2 is cooled forcibly, the temperature rise of the insulating oil 3 and the transformer coil 6 is restrained. Since the cooling fan 4 is arranged at a suction side of the heat sink 2, air flow at an air blow side is adjusted, the heat sink 2 reduces flow rate of air and the noise level is reduced.
