Title: Injection device and method for performing simultaneous suction and distribution of fluid
Inventor: POORU GAASUN
IPC: B01L3/02
Filed: 1997-03-18
Abstract: PROBLEM TO BE SOLVED: To provide an injection device, which can suck and distribute individual separated fluids when a single piston is moved on one direction. SOLUTION: Chambers 14 and 16 of an injection device 10 have ports 22 and 24, respectively. A piston 30 in the inside of the injection device has an intermediate section 36, which can be moved in the chambers 14 and 1 16, a first end-part section 32, which can be moved only in one chamber 14, and a second end-part section 34, which can be moved only in the other chamber 16. In this case, the end part section 34 has the diameter smaller or larger than the intermediate section 36. When the piston is moved in the first direction, sucking force is generated at one port 22, and distributing pressure is generated at the other 24. The opposite actions are generated at the respective ports 22 and 24 by the reverse movement of the piston. Furthermore, compressing seals 48, 54 and 56 are provided at the intermediate section 36 and end parts 42 and 44 of the chambers 14 and 16, which are facing to each other and are not neighboring.

Title: Liquid crystal display device
Inventor: SUEHIRO KEIICHI
IPC: G02F1/133
Filed: 1988-04-05
Abstract: PURPOSE:To obtain a liquid crystal display device having a resistance to foam generation in a cooling stage and having also uniform displayed color having no uneveness by using two-layered spherical bodies as spacers for keeping the thickness of a liquid crystal layer at a fixed value. CONSTITUTION:The title liquid crystal device is constituted of a liquid crystal cell held between a pair of polarizing plates 26, wherein said liquid crystal cell is constructed by sealing liquid crystals between a pair of transparent substrates 23, 24 having transparent electrode 22 on the inside surface. Two layered spherical bodies 21 are used as spacers for keeping the thickness of a liquid crystal layer 25 at a fixed value. Concretely, spacers consisting of rigid core parts 11 and relatively flexible shell parts 12 are dispersed in the liquid crystal layer in order to obtain a uniform thickness of the cell in a wide range, thus the shell parts are deformed. Thus, fluctuation of thickness of the cell due to deformation by pressure and unevenesses of the transparent substrate are absorbed by the core parts, and the unevenness of displayed color is eliminated. Or, if color unevenness is generated in a liquid crystal display device, the color unevenness is eliminated by collapsing the shell parts of the spacer in an area of large cell thickness by compression. Moreover, generation of foams in a cooling stage is also prevented because the contraction of volume of the liquid crystal can be followed up by the elasticity of the shell parts.

Abstract: PURPOSE: To attain the rationalization of a calibrating method and the improvement of analysis precision by obtaining a detection-amount line of excellent linearity by adding polyoxyethylene alkyl ether as a synergist to an inspection test solution using bromophenol blue.  
     CONSTITUTION: To an albumin inspecting test solution of 2W4 in pH containing bromophenol blue BPB preferably to 20W30ppm, polyoxyethylene alkyl ether POEAE is added within a recommendable range of 300W1000ppm. The most effective OPEAE is higher alphatic alcohol, esp. lauryl alcohol with ethylene oxide added to 8W15. Consequently, the blank test value of the test solution decreases by the hypsochromic effect of POEAE to BPB and at the same time, the detection amount line becomes nearly linear to simplify calibration by a few kinds of standard solutions, so that a test solution can be obtained which is of advantage to the application to an automatic analyzer.
