Title: Fiber holder of fiber type optical coupler producing apparatus
Inventor: NIIHORI OSAMU
IPC: G02B7/00
Filed: 1996-10-17
Abstract: PROBLEM TO BE SOLVED: To make it possible to manufacture a small-sized fiber type optical coupler at a low cost by using a column of a small diameter and a column or block worked to have the radius of curvature approximately equal to the radius of curvature of this column and bringing two pieces of fibers into tight contact with each other in nearly a point-to-point contact state. SOLUTION: Jigs 18, 19 for bringing the two fibers 15, 16 into tight contact with each other are capable of bringing the fibers 15, 16 into tight contact with each other in the form approximate to a point-to-point contact without breaking the fibers 15, 16, insofar as the shape of these jigs is the small-diameter column of >=1mm in diameter or the block worked to >=0.5mm in the radius of curvature at the front end. The shapes of the fibers between the coating parts and tight contact parts of the fibers 15, 16 are, therefore, symmetrical and the internal stresses generated in the fibers 15, 16 are nearly equaled. As a result, the jigs 18, 19 are formable to a smaller width and the parting of the fibers 15, 16 from each other in the production process of the fiber type coupler does not arise any more. The yield of the coupler production is thus improved.

Inventor: TAKATSU MANABU
IPC: B28B3/00
Filed: 1987-11-20
Abstract: PURPOSE:To make it possible to easily and accurately form a thin ceramic formed body with nearly uniform wall thickness by a method wherein ceramic produced by spraying granular ceramic between an electrode member and a metal mold or rubber mold, between which electric field is generated, so as to adhere to the mold is press-molded hydrostatically. CONSTITUTION:Electric field is generated between a mold 1 and an electrode plate 4. And granular ceramic is sprayed between the mold 1 and the electrode plate 4 from a spraying device, which is not shown. The sprayed ceramic is charged electrically and, after that, sucked to the under surface of the mold 1 through electrostatic force. Next, a pressure vessel 6 and a rubber mold 7 are shifted through a truck 2 just below the mold 1 so as to clamp the mold 1 and the pressure vessel 6 together by lowering the mold 1. After that, the ceramic adhered to the under surface of the mold 1 is press-molded hydrostatically by applying hydraulic pressure of 1000kgf/cm<2> on the back of the rubber mold 7 in order to obtain a thin bown-shaped ceramic formed body.

IPC: G01V3/11
Filed: 1991-08-23
Abstract: PURPOSE:To enable a metal detector to detect the passing of very small metallic impurities while noise signals are generated and the polarity of the signals is not inverted by constituting the detector in such a way that the detector is provided with a detecting means and differentiating means and outputs a metal detecting signal when the detector detects the minimum and maximum values of signals generated by the fluctuation of an induced voltage. CONSTITUTION:A metal detector is constituted in such a way that differentiating means 9 and 10 are provided after unbalanced signal detecting means 7 and 8 and the detector outputs 20 a metal detecting signal only when the minimum value of signals is detected when a prescribed period of time has elapsed after detecting the maximum value of the signals caused by the fluctuation of the induced voltage first detected by the means 9 and 10, Since the maximum and minimum sections of the signals are detected 7 and 8 and metal detecting signals are outputted 20 when the maximum and minimum sections exist even when the polarity of the signals is not inverted (from the maximum value to the minimum value), the passing of small metallic impurities can be detected 16, 19, and 20 even when the impurities pass while noise signals are generated. Therefore, not only the influence of noise can be, removed, but also metallic impurities can be surely detected. When a saturated state detecting means 21 is provided, in addition, even the passing. of large-sized metallic impurities can be surely detected.
