Title: Apparatus for producing optical fiber coupler
Inventor: FUKUMA MASUMI
IPC: G02B6/287
Filed: 1990-01-17
Abstract: PURPOSE:To obtain the optical fiber coupler which is less fluctuated in excess loss by using an optical fiber aligning part which can equal the bending, etc., of optical fibers by balancing the forces to be acted thereon. CONSTITUTION:Clampers 5 are imposed on stretching stages 6 for stretching the optical fibers in the axial direction and clamp the coating parts 2 of two pieces of the arrayed optical fibers from a transverse direction. Pressing parts 7 for the glass parts of the optical fibers press the longitudinal parts of the optical fibers where the coatings are removed by the specified tension from the vertical direction orthogonal with the clampers 5 at the time of welding. The pressing force applies the force by a weight 8 on yarn 9 in two directions so as to apply a specified load and is transmitted to linear bearings 10 which can be moved in the axial direction of the optical fibers via guide rollers 11 so as to balance the load. The forces to be applied on the fibers at the time of aligning the optical fibers are balanced in this way and the fluctuation in the excess loss of the optical fiber coupler is decreased at the time of welding in the production stage of the optical fiber coupler.

Title: Combustion device
Inventor: OTSUKA MASAYA
IPC: F23R3/30
Filed: 1995-01-23
Abstract: PURPOSE: To obtain an excellent flame-stability over a wide range from its activation to a rated value by a method wherein a separating plate arranged to direct from a flame holder toward an upstream side of a premixing device. CONSTITUTION: In the case that flames 10, 11 are formed on both sides of a flame holder 9 and a flow speed difference is generated between both flames 10, 11, a region of already-ignited gas is increased at a flame of slow flow speed and then an accelerating pressure loss is increased. Since the premixed gas is divided on an upstream side of a separating plate 12, a flow speed in a flow passage where the accelerated pressure loss is increased is further decreased. However, since a pressure difference on both sides of the separating plate 12 is released by an opening 15 arranged at the separating plate 12, a flow speed difference on both sides of the flame holding device 9 is not expanded, and then a stable flame is obtained.  In addition, even in the case that a back-fire occurs, it is possible to reduce a range of low flow speed region on one side of the separating plate 12, thereby an excellent flame-stability can be obtained over a wide range starting from its activation to a rated value.

A document size extracting part 110 extracts document size information from the transmitted signal, which includes document size information of a control signal, and sends the size information to a display control part 105. As the result, not only the document but also the document size is displayed on the display part 104. Consequently, an operator selects a form approximately equal to the displayed document size and can enlarge/ reduce the document.
