Title: Optical fiber ferrule and optical connector using the same
Inventor: KOBAYASHI YOSHIHIRO
IPC: G02B6/38
Filed: 1997-06-19
Abstract: PROBLEM TO BE SOLVED: To minimize a connection loss by forming the off center positional directional displaying part of the narrow pore of a ferrule on the outer surface of the ferrule and abutting one pair of ferrules each other so that these off center directions coincide. SOLUTION: A ferrule 1 is a cylindrical body having a narrow pore 1a for inserting and fixing an optical fiber and it is provided with a conical part 1b for making the optical fiber to be easily inserted at the rear end side of the narrow pore 1a and a chamfering 1c is formed at the outer circumferential part of the top end side of the ferrule. Moreover, an off center positional direction displaying part 1d consisting of a marking is formed at the outer circumferential side surface of the ferrule 1. That is, however it is unavoidable that the center of the narrow pore 1a is deviated a little with respect to the center of the ferrule, the direction of the off center of the pore is preliminarily measured and the displaying part 1d is formed in the direction.  Thus, at the time of constituting an optical connector by using the ferrules 1, when one pair of ferrules 1 are abutted each other so that off center positional direction displaying parts 1 coincide, off center directions of the ferrules coincide and the connection loss is made to be reduced.

Abstract: PURPOSE:To display the number of residual sheets with high accuracy by operating the number of residual sheets from a signal corresponding to the rise of sheets and a corresponding signal of the number of used sheets before rise to the height of residual sheets to display the number of residual sheets. CONSTITUTION:A microcomputer 50 first calculates the height of rise from a lower bound switch SW5 position of a tray to a position where the upper surface of stacked sheets is brought into contact with an upper bound switch SW4 by pulse number P1 of a disc pulse interlocking with an elevating motor M3, so as to find the pulse number corresponding to the height of sheets on the tray, P0=Pt-P1, from the pulse number P1 and all pulse number Pt between SW4 and SW5. After that, the pulse number on every rise with a decrease in sheets is summed up Pn to find the height of residual sheets, Px=P0-Pn, and the number of residual sheets, N=PxXn/Pn, is operated from the measured  number n to the sum Pn. This result is displayed on a display device 52 by  operation of SW8, and when a value larger than the number of residual sheets  is input to a preset counter 51, a shortage of sheets is alarmed by voice generators 53, 54.

Filed: 1985-07-25
Abstract: PURPOSE:To make the squelch sensitivity constant independently of the temperature change by connecting a circuit element having a temperature characteristic changing reversely a bias point of a noise amplifier agains its fluctuating direction. CONSTITUTION:A thermister Th1 representing a negative temperature characteristic is connected across a variable resistor VR1 connected to an output of the noise amplifier NA.

Abstract: PURPOSE:To increase the number of usable film classifications and to make an alarm indication possible to enhance the effect, by setting a specific film sensitivity of a relatively high frequency in use in case of a general cartridge which has not a code part. CONSTITUTION:When a general cartridge which has not a code part is loaded, the film sensitivity of ASA100 of a relatively high frequency in use is set, and a signal code G changes to H.
