IPC: G06F17/50
Filed: 1990-08-31
Abstract: PURPOSE:To further reduce a bisecting decision graph by deciding a temporary variable order for the bisecting decision graph, finding the further improved variable order, and searching the bisecting decision graph according to this variable order.

Filed: 1986-09-30
Abstract: PURPOSE:To increase the working range of a servomechanism for pressure control by providing the pressure regulators at both pressure supply and back pressure sides of a servo valve and changing the supply pressure and the back pressure of the servo valve in response to the generated pressure. CONSTITUTION:In a pressure control servomechanism, the pressure fluid supplied to a jet pump 2 from a supply pressure port 1 undergoes the control of pressure through a servo valve 3. The pressure generated by the pump 2 is supplied to a pressure generating port 4 and detected by a detector 5 to be compared with a pressure setting signal 7 by a servo amplifier 6. Thus the valve 3 is controlled. Here an upstream side pressure regulator 10 is used together with a downstream side pressure regulator 17. As a result, the pressure is reduced by the regulator 10 which works by the generated pressure controlled by the pressure fluid before this fluid is supplied to the valve 3. Then said reduced pressure is controlled by the valve 3 for generation of the desired pressure.
