Title: Method for polishing connected part of optical fiber in flame
Inventor: HAKAMATA NAOSHI
IPC: G02B6/255
Filed: 1984-04-25
Abstract: PURPOSE:To prevent cracking due to thermal strain and reduction in the strength of a connected part by putting parts of optical fibers to be connected by melt bonding in a heat resistant pipe and by heating the pipe from the outside to melt-bond the surface glass layers of the optical fibers together. CONSTITUTION:The heat resistant pipe 3 having a slit 31 is attached to two cooling stands 4. Optical fiber strands 2 are inserted into the pipe 3 from both ends of the pipe 3 after stripping the coatings 1, and the tips are brought into contact with each other. The pipe 3 is heated with a burner 5 from the outside of the contact part 21, and at the same time, an inert gas is fed into the pipe 3 from a cylinder 8 through a pipe 6 while controlling 7 the flow rate. The cooling stands 4 prevent the melting of the coatings of the optical fibers. After finishing melt bonding, the burner 5 is put out, and the resulting optical fiber is slowly cooled and taken out. Thus, cracking and reduction in the strength of the connected part can be prevented.

Abstract: PURPOSE: To obtain a quartz glass which has optically high quality and can be used for a photomask substrate or an optical fiber preform by subjecting a dry gel to sealing treatment, heating the gel to form a glass body or glass precursor and maintaining it at temp. higher than the heat treatment. CONSTITUTION: After a sol soln. containing a silicon compd. gels, the gel is dried to obtain a dry gel. The pares of the dry gel are sealed and the gel is heated at a first heating temp. to obtain a glass body or glass precursor. The obtd. glass body or precursor is left to stand, heated at a second temp. which is higher than the first heating temp., and maintained for a specified time to obtain a quartz glass. Then the quartz glass is cooled. In at least a part of the cooling process, the glass is gradually cooled. If large particles or impurities which are hardly vitrified are mixed in the source material, a complete homogeneous glass can not be obtd.

Title: Clock signal output circuit
Inventor: ISHII HIDEKAZU
IPC: H03K19/086
Filed: 1990-03-30
Abstract: PURPOSE:To reduce the trigger noise by providing first to third transistors TRs which have the emitters connected in common and connecting the base of the third TR to a DC bias source. CONSTITUTION:A third TR Q3 is provided which has the emitter connected to the common emitter of first and second TRs Q1 and Q2, and the collector of the TR Q3 is connected to a reference potential point, and the base of the TR Q3 is connected to a DC bias source VB. The value of the DC bias source VB is higher than the low level of the clock signal applied to the input and is made lower than the middle point between the low level and the high level. Consequently, a current flows to the TR Q3 while an in-phase clock input signal and an anti-phase clock input signal are inverted to perform switching between the high level and the low level, and therefore, they are not made active together at the time of inversion of an in-phase clock signal output and an anti-phase clock signal output as the output. Thus, the trigger noise is reduced.
