Patent JP-S593189-A (JP)
Title: Concrete pump
Inventor: TANAKA KATSUSHI
IPC: F04C5/00
Filed: 1982-06-28
Abstract: PURPOSE:To reduce local friction in a tube by providing a tube whose inner diameter is gradually reduced from the suction side towards the exhaust side and increasing the pressure in the closed section of the tube, thus reducing any reverse flow of concrete. CONSTITUTION:When preceding roller 7 starts to move away from tube 3 opening said tube, the suction (closed section) and exhaust sides partitioned by said preceding roller 7 acting as the boundary are communicated with each other. As the suction side is at a higher pressure, the reverse flow of the exhaust side concrete to the suction side is reduced. As said reverse flow of concrete cannot be stopped completely, local friction develops to some extent on the inner face of the tube 3 on exhaust side between A and C. As thickness 3' of this part has been increased and the eccentricity of the center of rotation O' of rotor body 4 is H, the compression at thicker part 3' of tube 3 is large and even if local friction develops, roller 7, 7' can close the opening passage of tube 3 completely.

Abstract: PURPOSE:To enable accurate assay and analysis with a limited analysis process, by arranging an antibody or an antigen prone to an antigen-antibody reaction specifically with a substant to be inspected on a liquid crystal molecule as converted to a solid phase to lead it to an antigen-antibody reaction with a sample. CONSTITUTION:A liquid crystal is used in place of an insoluble carrier and a liquid crystal molecule 10 is made to react with a sample 12 after an antibody or an antigen 11 allowed to an immunological reaction specifically with a substance 20 to be inspected is converted to the phase the same as the molecule. As a result, the liquid crystal molecule 10 bonded to the substance 20 being inspected by the immunological reaction changes in the orientation characteristic according to the substance 20 being inspected thus bonded thereto. Luminous flux emitted from a light source 18 is transmitted with a polarization plate 17 to be converted to a linearly polarized light and made incident into a reactor 13. As being at a random state, the liquid crystal molecule 10 in the reactor 13 acts on the incident polarized light as photodetector or work to turn the rotary surface of the incident polarized light. This enables direct assay of the substance 20 being inspected bonded to the liquid crystal molecule 10 by measuring the quantity of the polarized light passing through the reactor 13 thereby simplifying the analysis process.

Title: Door opening-closing device
Inventor: TSUJI SHIGERU
IPC: E05F15/16
Filed: 1993-05-14
Abstract: PURPOSE:To prevent occurrence of a large impact force or noise at the time of opening and closing of a shutoff door by providing a speed regulating mechanism which attenuates the speed of a vertical motion of the shutoff door in the vicinity of top and bottom dead points. CONSTITUTION:This device is so constituted that a shutoff door 1 is opened and closed by a group of gears 6 and 7 linked to each other and arms 9a and 9b rotating therewith. When the shutoff door 1 starts to descend from a top dead point, a component force of a load of the shutoff door 1 in the direction perpendicular to the long arms 9a and 9b is small and the descent of the shutoff door 1 is started at a slow speed. As the long arms 9a and 9b rotate, the component force generated by the load of the shutoff door 1 and acting to rotate the long arms 9a and 9b increases and becomes maximum in the state wherein the long arms 9a and 9b become horizontal, and therefore a descending speed also becomes the largest in this state approximately. When the position at which the arms become horizontal is passed, the componet force generated by the load of the shutoff door 1 and acting to rotate the long arms 9a and 9b becomes small and the descending speed of the shutoff door 1 also decreases consequently.
