Title: Liquid crystal display element
Inventor: TANAMACHI SHOICHI
IPC: G02F1/1337
Filed: 1988-06-29
Abstract: PURPOSE:To obtain a liquid crystal element which has high contrast and superior memory performance by orienting the internal surface of one of a couple of electrode substrates vertically and the internal surface of the other electrode substrate horizontally. CONSTITUTION:A vertical orienting layer 5 and a horizontal orienting layer 6 are formed on the surfaces of the glass substrates 1 and 2 and a seal part 8 is provided. Consequently, smectic liquid crystal 7 is charged in a sealed state in the space formed of said layers and seal part. One substrate of this liquid crystal element is oriented vertically and the other substrate is oriented horizontally, so the vertical orienting force is suppressed to some extent and a scatter state is maintained for a long time. Consequently, the liquid crystal display element which has the high contrast and excellent memory performance is obtained.

Abstract: PURPOSE: To measure an element for wide concentration range, always accurately and quickly by determining analyzed element quantity based on an analysis line selected by comparing the gradient of the regression line not passing the origin and that passing the origin with a predetermined value. CONSTITUTION: The spectrum light of analysis lines at two kinds of length (for example, C193.0nm and C165.8nm) for an element of which light is measured, is converted 12 to a photoelectric current. By using the spectrum intensity distribution of these two kinds of analysis line for an arithmetic circuit 14, the regression line IC190.0nm passing the origin O and the regression line I'C165.8nm not passing the origin O are calculated and the gradients a, a' of the two regression lines I, I' and the ratio k=a'/a are calculated in an arithmetic circuit 15. Then, with an arithmetic circuit 16, the ratio k is compared with a reference value stored in advance. When the ratio k is smaller than the reference value, the analysis line of C165.8nm with lower sensitivity is selected and when it is larger, the analysis line C193.0nm with higher sensitivity is selected. Based on the selected and determined analysis line, an analyzed concentration arithmetic circuit 18 calculates the concentration of the element (C).

Abstract: PROBLEM TO BE SOLVED: To enable the cleaning of molding sand stuck to a pattern with air- blow without lowering the raised pattern temp. by arranging an air heater in a piping route from an outer air supplying valve to an air blow nozzle. SOLUTION: Firstly, electric current is supplied into a heater 3 combined in a master plate 2 and the heat is generated to raise the temp. of the master plate 2. Then, the temp. of the pattern 1 is raised by heat transfer from the master plate 2 to the pattern 1. Under this condition, the molding is executed and since the molding sand is stuck to the pattern 1 after molding, the air is blown from the air blow nozzle 4 at each time of parting molds and the sand stuck to the pattern 1 is blown off to clean the pattern. At this time, the blown air is heated with the air heater 6, and since the heated air is blown onto the pattern 1, the temp. of the pattern 1 is not lowered and the good pattern drawability is obtd. even at the following molding.
