Title: Sealing device
Inventor: NISHIKAWA MASAHIRO
IPC: F16L23/16
Filed: 1989-03-22
Abstract: PURPOSE:To seal a simple opening portion by combining the front side tilted face of a pressing body made of shape memory alloy with the back side tilted face of a sheet presser in such a manner that they are capable of freely making sliding contact with each other, and pressing the sheet presser forward by means of heating of the pressing body for reducing its diameter, and opening/closing the opening portion of the apparatus main body by means of a sealing sheet. CONSTITUTION:The diameter of a ring-shaped pressing body 9 is reduced by heating the pressing body 9 made of shape memory alloy to temperatures above its transition temperature by a heater 11, and a mechanical force generated at that time is applied to a sheet presser B via the front side tilted face 9b of the pressing body 9 so that the sheet presser B is pressed forwards. A sealing sheet 10 is pressed toward a sheet receiving flange 3 by the sheet presser 8 so that its opening portion 2 is sealed. The temperature of the pressing body 9 is lowered by cutting off electricity transmission to the heater 11, and, when the temperature is lowered to below the transition temperature, the diameter of the pressing body 9 is enlarged so that the mechanical force acting on the pressing body 9 is eliminated. The sealing sheet 10 is thus made moveable, and its through hole 10a is made to agree with its opening portion 2 and then the heater 11 is actuated again so that the opening portion 2 is opened.

Title: Turbidity measuring apparatus
Inventor: SUGA AKIHIRO
IPC: G01N21/49
Filed: 1993-03-29
Abstract: PURPOSE:To accurately measure the turbidity by casting parallel luminous fluxes to a solution to be measured from a light source with different projecting angles, and measuring the turbidity from a light directly entering from the light source to a photodetector and a scattered light generated when the parallel luminous flux is projected to the photodetector with a constant angle. CONSTITUTION:In accordance with the rotation of a motor 11, a mirror 10 projects parallel luminous fluxes from a lamp 1 and a lens 2 with different projecting angles. When the mirror 10 is inclined as indicated by (a), the parallel luminous fluxes are projected directly to a photodetector 13. When the mirror 10 is in the inclined (b) state, the parallel luminous fluxes are projected to a cell 12 with an angle theta to the photodetector 13. At this time, the light passing through the cell 12 is not reflected at a glass surface 12B, but totally absorbed by a light absorption plate 12A, whereby the photodetector 13 detects a scattered light based only on the parallel luminous fluxes. The intensity of the passing light and that of the scattered light detected by the detector 13 are input to a sample hold circuit 14 through an amplifier 7. The circuit 14 holds the output of the amplifier 7 in compliance with a control signal from a position detector 15. The turbidity of the solution is calculated by an operating circuit 8 from the held signals of the passing light and the scattered light.

IPC: B29C65/50
Filed: 1990-03-20
Abstract: PURPOSE:To make it possible to smoothly stick tape to an object by pressure by a constitution wherein at least some part of suction holes are covered with masking member by being sucked to the outer peripheral surface of a revolving roller, when the tape is not fed to the revolving roller. CONSTITUTION:When tape 20 is not fed between the outer peripheral surface 10 of a revolving roller 1 and masking member 4, the masking member 4 is sucked along the region, which is nearly one-fourth of the total peripheral length of the outer peripheral surface 10, so as to cover suction holes 11 within said region, resulting in holding certain intensity of suction pressure at respective suction holes 11. Further, when the whole tape 21 is revolvingly moved under the state being sucked to the outer peripheral surface 10 of the revolving roller 1, suction force does not act on the tape-like masking member 4, since the tape 21 covers the suction holes 11 by being sucked to the outer peripheral surface 10. When the tape 21 is revolvingly moved to the sticking starting point B and hot air 5 is fed from heating device against the tape 21 and work 7, which is carried by carrying device 6 and the one surface side of which is pressed by the revolving roller 1, the tape 21 is efficiently sticked on the work 7.
