Title: Jig for forming end face protective film of semiconductor laser element
Inventor: ITOU YOSHIYUKI
IPC: H01S5/00
Filed: 1997-01-31
Abstract: PROBLEM TO BE SOLVED: To prevent the light emitting area of a semiconductor laser bar from being damaged by continuously forming second grooves from the bottoms of first grooves which are formed to a prescribed depth from the upper surface of a rectangular substrate from one side face of the substrate toward the other side face. SOLUTION: The width of an opening 4A is made broader than that of a semiconductor laser bar so that the laser bar may be housed in a groove 3A easily. In addition, the width of the groove 3A is made narrower than the height of the laser bar so as to suppress the adhesion of an end face protective material to the surface of an electrode as much as possible when end face protective films are formed on both end faces of the laser bar. When the end face protective films are formed by housing the laser bar in a first groove 3A, the light emitting area of the laser bar can be positioned above a second groove. Therefore, the light emitting area can be prevented from being broken and damaged, because the light emitting area has no contacting part.

IPC: B66B25/00
Filed: 1991-02-28
Abstract: PURPOSE:To provide a control device for an escalator, which can surely recognize a difference between a user on a wheel chair or a general user by embedding two band-like pressure sensitive sensors in the floor surface of an entrance section 1 of an escalator, in adjustment with the wheel widthwise pitch of the wheel chair. CONSTITUTION:A wheel chair detector 2 having marks 2a, 2b are laid at the entrance 1 of an escalator. When a user on a wheel chain comes to a stop on the marks 2a, 2b which also serves as a guide for the user on the wheel chair, the weight of the user is exerted to left and right pressure sensitive conductive rubbers 4a, 4b which therefore decrease their resistances below reference resistances 6a, 6b, and accordingly, comparators 7a, 7b are simultaneously turned on so that they can issue their outputs. Further, an AND circuit 8 for both comparators 7a, 7b delivers an output by which a counter circuit 9 is turned on after a predetermined time elapse, and accordingly, the user on the wheel chair can be detected. Even though a general user depresses the sensors by his foot, he never depresses both sensors, simultaneously, and accordingly, a difference between the user on the wheel chair and the general user can be surely recognized, thereby it is possible to provide a reliable control device for an escalator which can drive a wheel chair.
