Title: Recovery of ethylene oxide
Inventor: KAKIMOTO YUKIHIKO
IPC: C07D303/04
Filed: 1985-07-12
Abstract: PURPOSE:To enable the recovery of EO effectively utilizing the thermal energy of the column bottom liquid of an EO dissipation column, by heat-exchanging the column bottom liquid of an EO dissipation column with the column bottom liquid of an EO absorption column, recovering the thermal energy with a heat pump, and generating steam with the recovered energy. CONSTITUTION:The column bottom liquid of an ethylene oxide (EO) absorption column 2 is heated (5) to separate (7) inert gas, and supplied to the top of an EO dissipation column 10 to effect the dissipation and recover of EO (11). The column bottom liquid essentially free of EO and obtained from the bottom of the dissipation column 10 is introduced into a heat-exchanger 5 to carry out the heat-exchange with the column bottom liquid of the EO absorption column, passed through a refrigerant evaporator 51 such as a heat-pump, and cooled (18) to obtain an absorption liquid for the absorption column 2. The refrigerant evaporated in the evaporator 51 is compressed and sent to the refrigerant condenser 54, in which heat is transferred from the refrigerant to water supplied through the pipe 62 circulating the pipes 57, 58 and the tank 59 and steam is generated (60). The condensed refrigerant is circulated to the refrigerant evaporator 51.

Title: Adhesive sheet for polarizing plate
Inventor: YAMADA MASAKAZU
IPC: C09J7/02
Filed: 1996-06-13
Abstract: PROBLEM TO BE SOLVED: To obtain reliable liquid crystal display performance without generating foaming or peeling under severe high temperature and high humidity conditions even when there are differences in the manufacturing lots of polarizing plates or differences of volatile component rates by forming a pressure sensitive adhesive layer consisting of acrylic polymer on one surface of the polarizing plate and containing a volatile component in the layer. SOLUTION: The pressure sensitive adhesive layer consisting of acrylic polymer is formed on one surface of the polarizing plate and a 2.4 to 4wt.% volatile component is contained in the layer. Since the boiling point of a volatile component such as alcohol remaining in the polarizing plate is low, the component is easily volatilized and removed. Thereby an objective volatile component is mainly water. When the volatile component rate is <2.4%, the bending stress of the polarizing plate is increased and flexibility is reduced, so that air is easily included at the time of sticking the plate to a liquid crystal display cell. When the rate exceeds 4%, the contraction coefficient of the plate is increased due to the volatilization of the volatile component and it causes foaming or peeling.  Thereby it is preferable to set up the volatile component rate of the polarizing plate to 2.4 to 4wt.%.

Abstract: PURPOSE:To accurately and quickly position a probe by focusing an optical system observing means on a sample and a probe without moving the observing means or probe in the vertical direction by putting a refracting means which varies the focus between the optical system observing means and sample. CONSTITUTION:The position of a sample 14 is set in advance so that the sample 14 can be focused on the upper surface of a probe 18 by means of an X-Y-Z stage 12 by positioning the probe 18 in the luminous flux of an objective lens 15a. Then an inserting plate 21 is positioned in the luminous flux of the lens 15a by moving the plate 21 by means of a finely moving mechanism 19 for inserting plate and, when the focal distance of the plate 21 becomes longer, the sample 14 is focused. In other words, the thickness of the plate 21 is set. In such a state, a target point is searched by moving the sample 14 by means of another X-Y-Z stage 13. After searching, the plate 21 is moved out of the luminous flux and the probe 18 is moved to the target point on the sample 14 by means of a finely moving mechanism 16 for probe. Since an objective lens 12a is focused on the probe 18 in a state where the plate 21 does not exist, the probe 18 can be easily positioned to the target point on the sample 14, namely, to the center of the optical axis.
