Title: Preparation of optical fiber
Inventor: TSUKAMOTO MAKOTO
IPC: C03B37/027
Filed: 1983-08-29
Abstract: PURPOSE:To enable stable prepn. of optical fiber with small loss and high numerical aperture by prepg. optical fiber without interposing a stage for allowing a preform comprising core and clad to stand at ordinary temp. CONSTITUTION:A layer of glass having the same or smaller refractive index than quartz and larger coefft. of thermal expansion than quartz is laminated on the inside surface of a quartz pipe, and further a layer of glass having larger refractive index than quartz is laminated thereon. The pipe is then heated to make the pipe to a solid body, further, the glass rod obtd. by this treatment is polished by flame polishing successively to remove the quartz. Obtd. round rod 1 and a quartz pipe 2 are arranged concentrically by holding with holding tools 3, 4, and both are drawn by heating in a heating furnace 5 to form one body and optical fiber is prepd. simultaneously. Since, by this process, optical fiber is obtd. without a stage for holding a preform comprising different kind of glass having large difference in the coefft. of thermal expansion at ordinary temp.; optical fiber having high numerical aperture is obtd. practically, and, since the core glass and the interlayer glass are prepd. by the CVD process, the purity of obtd. optical fiber is elevated and the boundary region of the intermediate layer is uniform, and its light transmitting loss is small.

Title: Data checking system
Inventor: MUKOUGASA SHIGERU
IPC: G06F11/10
Filed: 1983-08-29
Abstract: PURPOSE:To identify the true cause of an error by preventing detection and holding of the error with use of an error correction code logic mechanism for write or read data in case an uncorrectable error is detected and held by the read or write data. CONSTITUTION:When a 2-bit error is detected at the side of a read data RD, the functions of both an error correction code logic EEC mechanism 12 and a holding mechanism 13 of the write data WD are blocked by the output signal of a holding mechanism 15 when an instruction of detection is closed. Then only the mechanism 15 of the RD side is turned on since the mechanism 12 has no actuation until a CPU2 executes a release instruction. In the same way, only the mechanism 13 is turned on when a write instruction is executed. The blocked mechanism 12 has no actuation in both read and write modes until the CPU2 executes the release instruction. Thus the true cause is identified for the error detected by the mechanism 12 just by reading mechanisms 13 and 15.

Title: Examination device for printed matter with entry number
Inventor: FURUYA SHINICHI
IPC: G06T7/00
Filed: 1998-06-05
Abstract: PROBLEM TO BE SOLVED: To provide an examination device for a printed matter with an entry number which enables interpretation of whether a pattern and an entry number are correct and all examinations to be completed through a single examination step. SOLUTION: A print difference between overlapped printing parts is determined by comparison using an overlapped printing part processing part 10, and when such a difference does not occur, the overlapped printing parts are interpreted as an identical print (failure in test because preconditions are not satisfied). Further when the difference occurs, an overall interpretation circuit 25 interprets whether causes for the generation of the print difference are due to only an entry number part in the overlapped printing part. When the results reveal that the causes for the generation are attributed to not only the entry number but also others, it is interpreted that the causes for the generation of the print difference are due to the pattern part in the overlapped printing part (failure in test on account of the pattern).  In addition, when the causes for the generation are due to only the entry number, the print differences are compared by an entry number part print difference comparison means. When the results reveal that the entry number print differences show a difference, it is interpreted that the causes for the generation are attributed to different entry numbers (passing the test because all the preconditions are satisfied).

Title: Oscillating device for welding torch
Inventor: SHIMADA TOSHIO
IPC: B23K9/30
Filed: 1977-12-28
Abstract: PURPOSE: To regulate automatically the amplitude of welding torch corresponding to the width of beveling of thick metal to be welded for multi-layered welding by the procedure in which the distance between weldment and welding torch is kept constant and then clutch is operated by the contact of contact needle with template.  
     CONSTITUTION: A profile roller moves up and down on the weldment W rotated by the motor 9, and thus the vertical relative distance between the welding torch T and the weldment W is kept constant. The predetermined speed of welding is kept by feedback movement drived by the detection of the profile roller. When the tip of rotating contact needle comes in contact with template, the clytch is electrically operated to make a changeover, whereby the reversed rotation is kept until the contact needle comes in contact with template. Thus, the proper adjustment of the position of the template permits the oscillating movement amount of the welding torch to be regulated to the optinum amount.

Title: Thermal transfer sheet and recording method
Inventor: MITSUSAKA KANJI
IPC: B41M5/382
Filed: 1999-06-04
Abstract: PROBLEM TO BE SOLVED: To provide a thermal transfer sheet which shows a sharp contrast between a recording part and a non-recording part and is capable of easily erasing the recording part by heat and also a recording method by which it is possible to erase the recording part of an image-recorded paper (a material to which an image is transferred) and reuse the paper. SOLUTION: In the thermal transfer sheet having a thermal transfer coloring layer containing a coloring compound, a color developing agent, a decoloring agent and a binder formed on a base material film, the heat transfer coloring layer is set to be in a color developing state in a recording part to which an image is transferred to a material for a transferred image by an interaction between the coloring compound and the color developing agent. Further, after the transfer recording, the decoloring agent preferentially dissolves either of the color developing agent or the coloring compound during the melting of the heat transfer coloring layer, and stops the color developing process as described to set the heat transfer coloring layer in a decoloring state.  That is, an image is recorded in the recording part by heat at below an erasure starting temperature and later the image of the recording part is erased by applying the heat at the erasure starting temperature or higher.
