Patent JP-S61160567-A (JP)
Title: Fuel injection valve for diesel engine
Inventor: MATSUI YUKIO
IPC: F02M61/20
Filed: 1985-01-08
Abstract: PURPOSE:To keep fuel pressure high even just before a needle valve takes its seat as well as to make a backflow of combustion gas not occur, by installing a pressure-regulating sleeve and also a pressure-regulating spring which energizes it so as to do its slide motion with the fuel pressure being somewhat lower than valve opening pressure. CONSTITUTION:A pressure-requlating sleeve 8 is provided with a pressure receiving surface 9, adjoining an oil sump 4, at its tip end, and one end of a pressure- regulating spring 12 comes into contact with its base end part with pressure, energizing it toward the tip end side. Working pressure in the pressure-regulating spring is set to be slightly lower than valve opening pressure in a needle valve 13. When fuel is fed to the oil sump 4 with pressure, the pressure-regulating sleeve 8 slides upward as in illustration, and in time of injection ending, it slides downward by dint of energizing force of the pressure-regulating spring 12 whereby substantial capacity in the oil sump decreases. In consequence, a sudden drop in fuel pressure is relieved to some extent so that such a pressure-regulating effect as being sufficient to prevent a backflow of fuel gas surely from occurring, is securable.

Title: Processing method of data correction of atomic absorption spectrophotometer
Inventor: YAMADA SHINJI
IPC: G01N21/31
Filed: 1988-01-09
Abstract: PURPOSE:To correct a background intensity value accurately, by taking notice of one sequence of data fetching and by correcting a time lag of a sampling time of a background signal intensity in relation to the signal intensity in said sequence. CONSTITUTION:One sequence of measurement is divided into three phases: a signal fetching phase 1, a background signal fetching phase 2 and a flame signal fetching phase 3. When a signal fetching time Sn is taken as a reference point, a background signal at this reference point Sn is determined in the following way. The background signal fetched at a fetching time Bn in the phase 2 is corrected on the basis of a background signal intensity obtained at a background signal extracting time Bn-1 one sequence before, and a background intensity value thus obtained is taken as the background intensity value in the sequence concerned. According to this method, an accurate background signal intensity value can be obtained even when there is a time difference between the time of signal fetching and the time of background signal fetching.
