Abstract: When finely aligning an optical fiber (7), attached in groove (9) of a carrier (1), with a surface area of an optical element (5) such as a laser, the plate-shaped carrier is plastically deformed by having suitable tools displace or act on the carrier at the end of the fiber (7), within a deformation region (17). For facilitating the plastic deformation slots (15) are made around the deformation region (17), so that a weakened area (16) is obtained quite at the end surface of the fiber (7). The fine alignment can be made either for correcting the position of erroneously mounted optical building elements or for a fine alignment of building elements, which have been mounted without necessarily trying to achieve a very high accuracy. The very alignment procedure can be executed when simultaneously measuring the efficiency of the interface, by activating the laser (5) to emit light into the optical fiber (7). This light can be detected by a light detector (25), so that the deformation process can be made in order to obtain maximum output power at the end of the fiber (7). The material of the carrier (1) can be a metal having a high degree of purity, for example copper plate of a small thickness. The fine alignment procedure as described provides advantages both in economy and in the degree of accuracy in the alignment operation, so that little attenuation is obtained in the interface between the building elements in the finished product. The carrier together with the building elements is intended for being moulded into a capsule in order to obtain an optical component suited to be mounted on a circuit board.

Inventor: FURUMIYA NAOAKI
IPC: G09F9/30
Filed: 2000-03-17
Abstract: PURPOSE: To realize an easy-to-see display of proper contrast according to an area occupied by light emitting pixels, namely, the number of the emitting pixels by providing this device with a current detecting circuit for detecting a current flowing into a cathode and a control circuit for controlling emitted brightness of EL elements according to the detected current. CONSTITUTION: When a display is performed where a large area of the whole screen is occupied by light emitting pixels, a current made to flow into a cathode common to each pixel is increased. Since a current detecting circuit 2 outputs an output voltage V1 divided by resisters R1 and R2, the resister-divided voltage V1 rises as the current flowing into the cathode increases. Since the following inverse voltage amplifier circuit 3 inversely amplifies the output voltage V1 from the preceding stage, the output voltage V2 decreases. And current amplification is performed by a current amplifier of the next stage and the output is supplied to a power source line. Thus, light emitting brightness of EL elements is controlled according to the number of the light emitting elements, therefore, it is possible to realize an easy-to-see display of a low power consumption and proper contrast.
