Filed: 1990-06-13
Abstract: PURPOSE:To facilitate the changeover of phase locked loop oscillators, to reduce the scale of constitution and to reduce the cost by providing a frequency divider circuit and a delay circuit to the oscillators. CONSTITUTION:A clock signal (a) is frequency-divided by a frequency divider circuit 3 and a reference signal (b) is fed to phase locked loop oscillators 1, 2. The signal (b) is at first inputted to delay circuits 11, 21, in which the signal is delayed by respective specified time and the result is fed to phase comparator circuits 12, 22 as phase comparison reference signals. The circuit 12(22), an LPF 13(23), a voltage controlled oscillator 14(24) and a frequency divider circuit 15(25) form the phase locked loop oscillation circuit in the oscillator 1(2) and signals c, d, e, f are outputted. In this case, when the delay time of the circuits 11, 21 is adjusted to make a prescribed delay to the output signals d, f from the oscillators 1, 2 with respect to the signal (b), the phase difference between the output signals c, d of the oscillator 1 and the phase difference between the output signals e, f of the oscillator 2 are almost eliminated and the oscillators are made small.

Filed: 1982-09-10
Abstract: PURPOSE:To change optionally the output voltage with an external control input, by switching the working point of a transistor TR which gives the ON/OFF control to an output control TR of a stabilized power supply circuit. CONSTITUTION:A stabilized power supply circuit consists of an output control TR11, a TR12 which gives the ON/OFF control to the TR11, a Zener diode D11, etc. Then a TR14 having a collector connected to a slider of a variable resistance R is turned on and off with an input given from an external control input terminal Vext. Thus the resistance value is changed between the base of the TR12 and a ground terminal GND, and the value is switched for the value of the voltage V2 which is compared with the reference voltage generated by the diode D11. As a result, the working point of the TR12 is switched to change the output of an output terminal Vout to a high and low level. In such a way, the output voltage can be optionally changed with an external control input.

IPC: B21J5/02
Filed: 1981-10-02
Abstract: PURPOSE:To improve production efficiency in hot closed forging by fixing sizing dies concentrically to the casting knock-out exit of a forming die and thereby performing sizing work immediately when the casting is knocked out. CONSTITUTION:A material W0 heated to warm-hot temperature is placed on a lower punch 3 which is raised to upper limit position. Then, it is lowered from the lower punch to lower limit position.
