Abstract: PURPOSE:To surely monitor and adjust the state of a demodulation circuit by providing a control voltage generating circuit outputting an upper limit when an integration value of the control signal exceeds a preset upper limit value and outputting the integration value as it is when smaller. CONSTITUTION:An output of an identification (A/D converter) 2 is inputted to an arithmetic circuit 5 through a delay circuit 4 and an output of a decoder (error correction circuit) 3 is inputted to the arithmetic circuit 5, the output difference is taken to obtain an error signal. A control signal generating circuit 6 generates a control signal according to a prescribed logic, a control voltage generating circuit 7 integrates an error signal and inputs a predetermined upper limit value when the integration value is larger than the upper limit value and inputs an output of the integration circuit as it is when the integration value is smaller than the upper limit to a clock adjustment circuit 8 to control a demodulator 1. Thus, the level of the control voltage is increased and the change in the control voltage near a level when a clock phase error is zero is increased, the state of the demodulator is surely monitored or adjusted.

Abstract: PURPOSE:To make the packing density of molding sand on the surface of a pattern uniform by compressed air flow and efficiently obtain a mold having sufficient hardness by providing a hollow chamber intercommunicating with a compressed air source in a squeeze table, and providing with a molding chamber securely thereonto. CONSTITUTION:A squeeze table 10 is moved upward to superpose a conveying molding board 7 on the under surface of a molding chamber 11, thereby forming a hermetic chamber in the chamber 11. Molding sand is packed in the hermetic chamber through a blow-in hole 21, and compressed air is supplied through small holes 6 into the chamber 11. This compressed air passes through the inside of the molding sand and is exhausted through a vent hole 18, an exhaust hole 16 and an exhaust hole 13. At this time, the packing density is made uniform to develop sufficient packing hardness near the surface of a pattern board 19 by moving and replenishing the molding sand. Hence, the board 19 is forced downward together with a squeeze plate 17, whereby the molding sand in the chamber 11 is squeezed. This molding mold is grasped between the board 19 and the board 7 and is pushed downward, by which the molding mold is removed.
