Abstract: PURPOSE:To make a voice transformer unnecessary, by connecting an electrostatic type microphone to one of a pair of input terminals constituting a differential amplifying circuit, connecting a capacitive element to the other, and obtaining a balance output from an output terminal of the differentail amplifying circuit. CONSTITUTION:A differential amplifying circuit 4 is constituted of a pair of N- channel field effect transistors TR1, TR2 and resistances R1-R5. In this case, a resistances R1 and R2, and R3 and R4 are made to have a same value. Large resistances R6, R7 having a same value, and an N-channel field effect transistor TR3 for forming a constant current source, and a resistance R0 are connected between one end A of the resistance R5 and a gate of TR1, TR2, and between a point A and earth, respectively. Accordingly, a drain current ID of TR3 is the sum of a drain current ID1 and ID2 of TR1, TR2, and is constant. A symmetrical property of the circuit is maintained by connecting an electrostatic type microphone M1 and a capacitor C1 between a gate of TR1 and earth 7. and between a gate of TR2 and earth, respectively. Since there is no input signal to the gate of TR2 from output terminals 5, 6 of the differential amplifying circuit 4, a characteristic of the microphone M1 is outputted as it is. In this way, a device which requires no output transformer is formed.

Title: Sprue rod of lost foam pattern
Inventor: KATO KAZUHIRO
IPC: B22C9/04
Filed: 1996-02-29
Abstract: PROBLEM TO BE SOLVED: To provide a sprue rod made of expanded resin foam hardly causing casting defect such as gas defect, sand mark. SOLUTION: This sprue rod 7 having a hollow part 6 is inserted into a sprue cup 13. The diameter of the hollow part 6 is continuously reduced form the end surface 8 at the molten metal supplying side of the sprue rod 7 toward the other end surface 9 to form the hollow part 6 so that its tip part 10 reaches the other end to be formed into a reverse cone state surface 9. At the time of pouring molten metal into the sprue rod 7 from the sprue cup 13, the expanded resin foam surrounding the hollow part 6 is thermally decomposed while filling the hollow part 6 with the molten metal. At this time, since the quantity of the expanded resin foam forming the sprue rod 7 is small, the gas quantity accompanying the thermal-decomposition of the expanded resin foam is small, the gas defect is hardly caused. Further, the nearer the bottom part of the sprue rod 7 is, the higher the pressure of the gas produced when the expanded resin foam is lost is, thus molding sand 2 adjacent to the sprue rod 7 is hardly collapsed.

The control valve 7 is controlled by a controller 20 receiving the detected valves of a detector 15 for operations of slewing and lever and a detector 17 for the slewing angle of the slewing base and also the set value thetaf of setters 19A and 19B for the slewing stop angles of the slewing base. The actual speed V between slewing start angle thetas and stop angle thetaf of the slewing base is matched with a speed Vx to be previously given as a function of the slewing angle theta by the controller 20. Also, during the overrun period, the control valve 7 is controlled in such a way as to match the actual speed V with the functional speed Vx' of the overrun angle theta. The automatic slewing controllability can thus be raised.
