Abstract: PURPOSE:To obtain a bulb which will not be cracked by forming a recess at one side of the cut section of an exhaust tube while bringing the distance from the bottom face of said recess to the tip of the cut sectiom into the specific range thereby stabilizing the shape of the cut section of the exhaust tube and reducing the fluctuation of the thickness at the cut section. CONSTITUTION:The exhaust tube 2 of a fluorescent lamp body or a bulb body 1 is cut at the tip, where a recess 4a is formed at one side of said cut section 4 while a projection 4b is formed at the opposite side. The distance H from the bottom face of the recess 4a or the tip of the recess 4a in the exhaust tube 2 to the tip of the projection 4b is made in the range of 3-8mm.. Consequently the thickness at the cut section 4 will never be too thin locally, thereby the crack or the breakdown will never occur. Since a pair of gas burners are faced at the intermediate section of the exhaust tube, while the height at the center of the heating section of the exhaust tube is shifted by 1-3mm. to the left and right then heated with approximately same firing force, a bulb having the shape of the exhaust tube cutting section described above can be obtained easily.

Title: Production of polarization maintaining coupler
Inventor: ABE TAKAHIRO
IPC: G02B6/28
Filed: 1988-08-04
Abstract: PURPOSE:To obtain the polarization maintaining coupler which maintains the low deterioration of an extinction ratio, decreases a light loss and has excellent environmental characteristics by partly removing clads and stress imparting parts from the section of respective optical fibers to a half moon shape and adhering the fibers by heating and melting. CONSTITUTION:Two pieces of the polarization maintaining fibers F, F' which are subjected to an etching treatment and are individually produced are so fixed to a fiber holder that the etching surfaces E come into contact with each other and the fibers are paralleled. The etching surfaces E are fully or partly heated and melted by an oxyhydrogen burner, etc., and are adhered to each other to form a coupling part B. The stress imparting parts 4, 4' joined to the two cores exist in the integrated clad. Since the respective fibers are horizontally chipped, the fibers cannot rotate freely with each other at the time of heating and melting and the stress imparting parts 4, 4' exist uniformly on both sides of the core. The clad does not exist between the two stress imparting parts 4, and 4' which are joined. Since the dispersion of the stress directions is obviated in this way, the deterioration of the extinction ratio is obviated and since the excess stress imparting parts do not exist between the cores, the polarization maintaining coupler having the small light loss is obtd.

Abstract: PURPOSE:To set the repeat function and the repeat period in response to the type of the key switch for a keyboard device having the repeat function, by selecting the type of the strobe signal in accordance with the key code. CONSTITUTION:Receiving a key code and the signal showing that a key is pushed from a key controlling part 2, a selection signal producing circuit 5 decides the presence or absence of the repeat function and the duration of the repeat period for the corresponding key code. If no repeat function exists, the circuit 5 feeds the selection signal (a) to a strobe signal producing circuit 6. When it is decided that the repeat function exists with a long repeat period, the signal (a) is delivered to a strobe signal producing circuit 7. While the signal (a) is delivered to a strobe signal producing circuit 8 in case the repeat period is short. Therefore, the key codes corresponding to the presence or absence of the repeat function as well as to the duration of the repeat period are delivered from an output controlling circuit 4 in response to the key switch.
