A collimator lens for an optical fiber is disclosed. The collimator lens comprises a cylindrical member having an effective radius R and effective axial length L. The cylindrical member is formed of optically transparent material having refractive index n.sub.1. The cylindrical member has one circular end portion provided with a connecting portion connectable with a light emitting end face of an optical fiber and the other circular end portion provided with a fresnel lens pattern having a positive focal length F. The focal length F, the effective length L, the effective radius R and the refractive index n.sub.1 are satisfied with the following formula (I) and (II);F/L=tan {sin.sup.-1 (NA/n.sub.1 }/tan {sin.sup.-1 (NA)} (I)R.gtoreq.L.multidot.tan {sin.sup.-1 (NA/n.sub.1)} (II)in which NA is numerical aperture of the optical fiber.
摘要:
A novel weighting device for draft rollers, in which a diaphragm is provided, as a pressing unit, above each top side roller. The diaphragms provided on a spinning frame are classified into a plurality of groups corresponding to species of rollers such as front rollers, middle rollers, and back rollers. Each group of diaphragms has common piping having a regulator for air pressure and branched to the diaphragms belonging to the group. One end of the piping is connected to a common high pressure air source, from which air of a uniform pressure controlled by the regulator is supplied to the diaphragms belonging to the group. Since a weighting force onto a top side roller is a function of a air pressure supplied to the diaphragm, it can be changed or diminished at once in a centralized manner by adjusting the regulator. Therefore, troublesome adjustment of individual pressing units is unnecessary.

An electric steering lock apparatus that protects an actuator from overheating without enlarging the actuator. The electric steering lock apparatus includes a lock pin engaged with a steering shaft to lock the steering shaft. An actuator moves the lock pin between a lock position in which the lock pin is engaged with the steering shaft and an unlock position in which the lock pin is disengaged from the steering shaft. A control unit controls the actuator. The control unit generates a calculated value related to operation time of the actuator and suspends operation of the actuator when the calculated value is greater than a predetermined operation suspension threshold value.

Described is a transparent electroconductive material composed of a transparent synthetic resin substrate and a transparent electroconductive film formed on the resin substrate. At least a surface portion of the resin substrate on which the electroconductive film is formed satisfies a requirement represented by the formula: F x Hv=0.4 wherein F is the mole number (.mu.mole/cm.sup.2) of a basic dye that can react with or adhere to the unit area of the surface of the synthetic resin, and Hv is the Vickers hardness as determined according to JIS Z-2244. The absolute value of the photoelasticity constant of the resin substrate below the glass transition temperature thereof is not larger than 15 Brewsters. A preferred transparent electroconductive material is prepared by coating an active energy ray-curing composition satisfying a requirement represented by the above formula on a surface of the transparent synthetic resin substrate having the above-mentioned absolute value of the photoelasticity constant; curing the composition with active energy rays; and forming a transparent electroconductive film on the coating layer by a low-temperature sputtering method at a temperature lower than 100.degree.

摘要:
A mechanism for driving the nipper shaft of a comber provided with a plurality of combing units, wherein a driving shaft and a nipper shaft are extended along the longitudinal direction of the comber. An eccentric disc is rigidly mounted on the driving shaft. A slider link motion mechanism is provided with a slider connected to the eccentric disc in such a condition that the slider is capable of reciprocally displacing along its own displacing passage when the eccentric disc is driven. One of the link elements of the slider link motion mechanism is slidably engaged with the slider so that a swing motion about a fulcrum thereof is created. The other link element of the above-mentioned mechanism is mounted on the swing shaft and, therefore, a quick return motion of the reciprocal turning motion of the swing shaft can be created.
摘要:
This invention is applicable for carrying out the doffing operation of several types of fly frames such as a fly frame provided with an upper rail having a plurality of flyers in suspended condition and a mechanism for driving these flyers therein, and a fly frame provided with a spindle rail and a bobbin rail disposed at a position above the spindle rail in such a condition that the bobbin rail can be displaced vertically during the building motion. According to the doffing method of the present invention, when it is required to carry out the doffing operation, the bobbins containing a full yarn package are relatively displaced to a position free from the corresponding flyers and the engagement of the bobbins with the corresponding bobbin driving mechanisms is released. Next the bobbins containing a full yarn package are carried toward a longitudinal end of the fly frame in a space above the arrangement of the bobbin driving mechanisms. In the preferable embodiment of the present invention, the carrying passage of the bobbin coincides with an alignment of the axial centers of the flyers arranged in the longitudinal direction of the fly frame. A chain conveyer is preferably used for carrying the bobbins. When the bobbin are carried to a longitudinal end of the fly frame, they are discharged from the fly frame. A fresh bobbin supplying device for supplying bobbins to the chain conveyer can be satisfactorily used.
