Title: Method for regenerating liquid etchant
Inventor: SHIMOMURA TADASHI
IPC: C23F1/46
Filed: 1998-09-18
Abstract: PROBLEM TO BE SOLVED: To provide a method for regenerating a liq. etchant with its composition changed after treating a metal consisting essentially of iron.

Title: Optical analyzer and calibrating method thereof
Inventor: EMIRU SEI
IPC: G01N21/85
Filed: 1991-10-14
Abstract: PURPOSE: To improve reliability without involving any movable part by comparing two amplitude reading values, comparing the residual values of calibration reading for values based on the known absorption properties of a filter, and adjusting calibration from derived values. CONSTITUTION: A CPU 22 allows a calibration lamp 4 to emit light. The light at a measurement wavelength is absorbed by 30% by a calibration filter 10. Non-absorbed light passes through a bundle of optical fibers 14 and reaches sample cell 12, where one portion is absorbed. The non-absorbed part passes through a bundle of optical fibers 16, becomes two beams, the spectrum part is detected by measurement and reference detection meters 6 and 8, and the non-absorbed part is supplied to a CPU 22 as an electrical signal with an amplitude. The CPU 22 divides a digitized measurement value by a corresponding reference value and makes the quotient into logarithmic value. Measurement reading value and calibration value obtained previously are effectively compared to eliminate the effect of the liquid sample 18 from a calibration reading value.  Then, the residual value is compared with the absorption value of the known filter 10, thus calibration adjustment is determined.

Title: Gas pressure measuring apparatus of accumulator
Inventor: KOBAYASHI KAZUHIKO
IPC: F16H63/12
Filed: 1987-10-20
Abstract: PURPOSE:To easily judge whether the pressure of gas is normal by making it possible to measure the amount of oil corresponding to the pressure of the gas allowed to fill an accumulator, by returning the operating oil stored in the accumulator to an oil tank and measuring the amount thereof. CONSTITUTION:When the pressure of gas is lowered by the leakage of the gas in an accumulator 20, operating oil is stored in the accumulator 20 corresponding to the leaked amount of the gas and, therefore, the operating oil after stored in the accumulator 20 is returned to an oil tank 40 and the oil level thereof is measured to detect the amount of gas leakage by a seal 50. Since the amount of the operating oil increasing corresponding to the gas leakage is affected by the operating pressure thereof, in order to reduce this error cause, the level difference of the operating pressure at the time of actual operation between at a high pressure time and a low pressure time is also measured other than the level at the time when the operating oil stored in the accumulator 20 is returned to the tank 40. By this method, the amount of oil corresponding to the pressure of gas can be measured.

Abstract: PROBLEM TO BE SOLVED: To improve radar clutter suppressing performance for enabling sufficient suppressing of clutter even under a strong radar clutter environment. SOLUTION: A radar pulse of a predetermined frequency is emitted from a transmitter 101 at a predetermined repetition period.
