Filed: 1982-10-27
Abstract: PURPOSE:To provide a hydraulic servo-valve which can be simplified in structure and be easily adjusted and attain high accuracy and high responsibility by disposing a pilot spool in a through hole of a rod member projected on the peripheral surface of a main valve to form a hydraulic bridge between an oil pressure source and a drain. CONSTITUTION:The end portion of a feed-back rod 3 is provided with a through hole 3a which is circular in section and disposed in parallel to the axis of a spool 2, and a pilot spool 4 is fitted in the hole in such a manner as to freely slide axially and turn on the axis. When a motor 5 is turned in the arrow direction, an opening of a variable orifice 10a is increased, and an opening of a variable orifice 10b is reduced. With such movement, the spool 2 moves to the left, and the feed-back rod 3 moves together, so that the opening of the variable orifice 10a is gradually reduced, and the opening of the orifice 10b is increased. This results in that pressure chambers 9a, 9b has the same pressure to stop the movement of the spool 2, thereby positioning the spool 2.

Title: Selector for set value of closed loop control circuit
Inventor: KIDA KENICHI
IPC: G05B7/02
Filed: 1980-12-27
Abstract: PURPOSE:To prevent the abnormality of a system by performing selection of the set value from a computer and the set value from an operator station in two stages first up to a controller then up to a control object. CONSTITUTION:The set values from a computer 1 and an operator station 2 are selected by the contacts 9, 10 of the 1st relay 7. A controller 3 compares the set values and the feedback signal from the object 5, and outputs command values to an electric motor value positioner 4. Here, when the 1st relay 7 is disabled, contacts 20, 22 make first, and contacts 19, 21 break. At the same time, contacts 13 break as well, and the self-latching of the 2nd relay 6 is released and therefore contacts 15, 17 break and the output of the electric motor valve positioner is disconnected. When a new set value is applied from the station 2, and the 3rd relay 3 is operated in putting the set pulses thereto, the 3rd relay 8 is latched by contacts 12 because it has approximately the same constitution as that of the 2nd relay 6. At the same time, contacts 16, 18 make and since the contacts 20, 22 of the 1st relay 7 make, the output of the positioner 4 is connected to the object 5.

During this period grain temperature TC1 is measured (S-108), and if a temperature not less than a specified temperature TC is detected (S-109), outside air ventilation drying (S-110) is effected and storage drying is restored. After the detected moisture content MS 1 of the grain reaches the target value MS, a ventilator is stopped and the grains are circulated for a period of T3 at intervals of T1 (S-113).
