Abstract: PURPOSE:To reduce the interface state density substantially by a method wherein, after a protective insulating film has been formed, heat-treated and cooled in a high- temperature hydrogen atmosphere, it is heat-treated in an inert gas atmosphere which has taken the place of the hydrogen atmosphere. CONSTITUTION:After a final protective insulating film has been formed, it is heat- treated in an atmosphere where high-temperature hydrogen of over 380 deg.C exists or where a gas containing hydrogen exists. Then, after the film has been cooled to a temperature of under 350 deg.C and an inert gas atmosphere has taken the place of the previous atmosphere, the treatment is completed. For example, after the temperature for treatment has been raised from a starting point A to a point B of 400 deg.C, the power supply for a heater 7 is turned off at a point C and then a cooling process is started. The starting point for treatment E is a nitrogen atmosphere of atmospheric pressure, the atmosphere is switched to a hydrogen gas atmosphere at a point F and at the same time the pressure inside a tube 1 is increased. From a point G where the pressure has reached 3 atm. to a point H where the temperature has been cooled to 280 deg.C, the state of high pressure is kept. After that, the atmosphere is switched to a nitrogen gas and at the same time the pressure is lowered. At a point I where the pressure has reached 1 atm., the treatment is completed.

Title: Driving method for control valve
Inventor: INOKUCHI IWANE
IPC: F15B13/044
Filed: 1984-09-10
Abstract: PURPOSE:To improve response and precision, by a method wherein, when a moving valve body is restored to a neutral position, after the moving valve body is energized in a restoring direction for a given time, it is energized in a displacing direction before restoration for a given time. CONSTITUTION:A first timing means 15, which, when a moving valve body 12 is restored to a neutral position, energizes a driving means 14 of the moving valve body 12 in a direction, in which the moving valve body 12 is restored to the neutral position, for a first given time, is connected to a second timing means 16 which, thereafter, energizes the moving valve body 12 in the displacing direction of the moving valve body 12 before restoration to the neutral position for a second given time. Thus, an energizing force in a restoration direction and an energizing force in an anti-restoration direction can be exerted, in turn, on the moving valve body 12 during restoration of the moving valve body 12 to the neutral position. This permits the moving valve body 12 to be rapidly and reliably restored to the neutral position, resulting in improvement of response and precision.
