Title: Purification of waste oil of mold lubricating oil used in cold forging process
Inventor: NAKAJIMA MITSUO
IPC: B01D15/00
Filed: 1987-10-16
Abstract: PURPOSE:To economically produce a reclaimed oil having a high purification degree, by homogeneously dispersing a mixture of diatomaceous earth and active China clay in the waste oil of a mold lubricating oil and subsequently subjecting the resulting dispersion to centrifugal treatment to remove impurities in the waste oil. CONSTITUTION:Preferably approximately 5wt.% mixture of diatomaceous earth and active China clay preferably in a wt. ratio of 3:2-3:7 is added and homogeneously dispersed in the waste oil of a mold lubricating oil used in a cold forging process. The resulting dispersion is treated by a separator normally having a centrifugal force of approximately 1000-3000G (more preferably 5000G) to remove impurities in the waste oil, thereby providing a clear reclaimed oil.

Title: Capacitance type sensor for detecting fluctuation of mass or diameter of elongated fiber test sample
Inventor: NIIKURAUSU HIRUDEBURANTO
IPC: G01G3/00
Filed: 1993-09-14
Abstract: PURPOSE: To eliminate or reduce shape effect and position effect by masking the area of a measuring slot end part with a guide. CONSTITUTION: Guides 5 are formed into two legs of a U-shaped guide member 7 so that they can be inserted and fixed into a measuring slot 3. The guide member 7 is formed by bending a band material having a groove-like section into U-shape, it has a base bottom part forming the guides 5 and a side protruding part 8 protruded in a collar form from the base bottom part, and is fixed into the slot 3 in the traveling direction of a test sample by the protruding part 8. When both side end part areas of the slot 3 are masked with the guide 5 by about 10%, respectively, the increasing change of sensitivity is substantially less than about 10%, and when they are masked to about 15%, the maximum sensitivity change is less than about 4%.  Since the test sample is guided to a position having a prescribed distance from an electrode 4 by the guides 5, the measuring error by shape effect or position effect is remarkably reduced.

Abstract: PURPOSE:To determine the existence of accelerating operation and to change the rate of acceleration in accordance with the operation of this pointing device by controlling the display position of a display body based upon the added result of outputs from an acceleration rate setting means for setting up the rate of acceleration based upon pressure force or the like applied from the outside and a momentum detecting means. CONSTITUTION:When a ball 1a is rotated without pressing it downward at the time of applying the pointing device 1 to a track ball e.g., a momentum detecting means 2 detects the rotation, and since pressing force to a pressure sensitive rubber 7 included in the acceleration rate setting means 3 becomes zero, the output of A/D converter 7 through a current/voltage converter 8 becomes zero and the cursor to be the display body is moved in a state suppressing acceleration control. At the time of rotating the ball 1a while depressing it, the output from the converter 9 is increased in accordance with pressing force and positional control is executed by an additional output part 4 so that the moving distance of the cursor is increased. Thus, the existence of accelerating operation can be determined and the rate of acceleration can be changed in accordance with the operation of the pointing device.

Abstract: PURPOSE:To reduce input conversion noise of a reproducing circuit and to improve the voltage reduction characteristics of a source voltage by providing diodes for leak current prevention between collectors and the load resistance of a current supply path, connecting a power source to recording and reproducing heads, and connecting a transistor (TR) couple for differential amplification to the recording and reproducing heads respectively.

Consequently, the number of diodes is decreased and equivalent input resistance is made small to reduce input conversion noise of the reproducing circuit. Further, the recording and reproducing heads are connected to a power source in series and the dynamic range of a voltage amplitude generated by the counter electromotive force is increased to improve the voltage reduction characteristics of the source voltage. Further, the differential amplifying TR couples of a recording circuit are connected to the recording and reproducing heads directly, so the dynamic range of the voltage amplitude generated in recording is increased, thereby further improving the voltage reduction characteristics of the source voltage.

Filed: 1997-09-29
Abstract: PROBLEM TO BE SOLVED: To recover a phosphor having an excellent characteristic with an excellent yield by treating a rough phosphor obtained by separating a solid phase containing a phosphor from a used developer containing the phosphor, by water. SOLUTION: A developer, which has dissolved a composition A containing a used phosphor when patterning is performed by using a developer containing hydoxide or salt of alkaline metal or alkaline earth metal in the photosensitive resin composition A is filtrated, centrifugally separated and naturally precipitated to separate a solid phase containing the phosphor from a liquid phase by a prescribed temperature and time. After an obtained rough phosphor is washed by water, the phosphor is recovered by using filtration, centrifugation and natural precipitation.  Separating efficiency of alkaline metal or alkaline earth metal contained in the rough phosphor can be enhanced by treating the rough phosphor by an acid, and the concentration of these metals can be set not more than 2 wt.%, which is desirable from the viewpoint of a change in light emitting luminance and chromaticity, and the concentration can be reduced further by repeating this water treatment.

Title: Terminal structure of optical connector
Inventor: YAMAUCHI KENJI
IPC: G02B6/36
Filed: 1988-10-21
Abstract: PURPOSE:To prevent peeling of the end faces of a built-in fiber which is shorter than the length of the small-diameter hole of a glass tube and a fiber connected to this built-in fiber by providing the built-in fiber and providing a specified spacing between the end faces of this built-in fiber and the fiber connected thereto, and then packing an adhesive agent having elasticity into this space. CONSTITUTION:The fiber end face 11a of the right side (connecting fiber side) of built-in fiber 11 adhered and fixed to the glass tube 10 is polished aslant. The cut end face 12a of the connecting fiber 12 is cut nearly square to the fiber axis and plane by stress rupture. The spacing is made between the fiber end face 11a of the built-in fiber 11 and the cut face 12a of the connecting fiber 12 and the adhesive agent 13 eventually fills this spacing if the adhesive agent 13 having elasticity is injected into the small-diameter hole 10a of such glass tube 10 and the connecting fiber 12 is inserted and fixed thereto. Even if the built-in fiber and the connecting fiber are moved in the direction where the fibers part from each other by thermal expansion in high-temp. environment, such movement is absorbed by the elongation of the adhesive agent and, therefore, the peeling between the fiber and faces is surely prevented.
