Title: Reference liquid for measuring ion activity
Inventor: TERAJIMA MASAAKI
IPC: G01N27/26
Filed: 1985-10-30
Abstract: PURPOSE:To prevent the generation of a junction potential and measuring error regardless of a great change in the intensity of ion in a sample, by containing a lithium salt having a pair ion with the ion mobility substantially equal at the concentration of at least 1M. CONSTITUTION:A lithium salt having a pair ion with the ion mobility substantially equal is contained into a reference liquid which applies a differential type ion activity measurement using an ion selection electrode pair at the concentration of at least 1M. Here, a reference liquid which contains lithium acetate or lithium propionate at the concentration of at least 1M is preferable in that the drift is small after the start of the measurement. This reference liquid has a small junction potential (JP) which will be generated at a liquid junction in the measurement by differential type of the activity of ions in blood of a mammal using an ion selection electrode couple, especially K<+>, Na<+>, NH<+>, Cl<->, CO<-->3 and the like in human blood. This can minimize the JP to be generated at a liquid junction and changes in the concentration of specific ions in a liquid to be inspected makes the error in the measured values of the ion activity due to the JP negligible in practice because the generation of JP accompanying those changes.

Filed: 1990-09-12
Abstract: PURPOSE:To enable inspection of a pattern only by an optical microscope without using an SEM by generating a pattern of a large area with a small dose to a dose which is necessary for formation of a fine pattern. CONSTITUTION:An active layer 2 is formed on a GaAs semiinsulating substrate 1 and a source electrode 3 and a drain electrode 4 are formed thereon. After a photoresist 5 is applied, a fine pattern for gate formation is directly generated. Thereafter, a pattern of a large area for monitor is directly generated on the same surface as the fine pattern. When development is carried out, a dose A of the fine pattern and dose B of the pattern of a large area are made A>B and a rate of A and B is selected; thereby, a fine pattern [3 and a pattern 7 of a large area can be formed simultaneously in the same development conditions. If inspection is carried out after development using the pattern 7 of a large area as a monitor, it is possible to carry out judgment without directly inspecting the fine pattern 8, thereby enabling inspection only by an optical microscope.
