Title: Pulse generation circuit and ultrasonic diagnostic device using the circuit
Inventor: KONDO TOSHIRO
IPC: H03K3/57
Filed: 1994-06-07
Abstract: PURPOSE:To improve S/N and the resolution of an ultrasonic image by applying positive or negative DC voltage to the center tap of the initiary coil of a pulse transformer and to apply pulse voltage to both terminals of the primary coil by making and breaking the electronic switch of the same characteristics. CONSTITUTION:In the period of turning on and off the respective electronic switches Q1 and Q2 impressing input signals I1 and I2, the voltage of an input signal I3 is not impressed to the gate of an electronic switch Q3 in a switch circuit 5 to be in an off state, and after passing the period, the input signal I3 is impressed to the gate of the switch Q3 to make the switch Q3 into an on state. As the result of it, the secondary coil L2 of the pulse transformer T is short-circuited so as to make the signal source impedance looked at from an output terminal 4 have a low value close to the on resistance of the switch Q3. Thereby, concerning output pulse voltage Vo' from the terminal 4, a waveform does not collapse even at the lowest part of the pulse string of output voltage to make all the pulse strings keep the same waveform so that positive voltage and negative voltage become symmetrical. Consequently, they are the same in frequency spectrum of waveform.

Title: Magnetic attraction device of sintered layer
Inventor: HARAKAWA TETSUMI
IPC: C22B1/20
Filed: 1995-06-14
Abstract: PURPOSE: To reduce power consumption required for magnetic levitation by detecting a level in the extending direction of a central line on the surface of a sintering layer and raising a current value of a normal conduction electromagnet when the detected level is low and lowering the current value when the level is high. CONSTITUTION: Normal conduction electromagnets 1 to 3 provide a magnetic attraction force opposed to the surface of a sintered layer 10. A level detection means 16 detects a level of the sintered layer 10 extending on its surface. A power feed control means raises a current value of a normal conduction coil 1 when the detected level is low by way of a second power source circuit which feeds power to the normal conduction coil 1 of the normal conduction electromagnets 1 to 3, in conformity with the level detected by the level detection means 16 and lowers the current value of the normal conduction coil 1 when the detected level is high.  In this manner, the coil current is controlled in conformity with a gap produced between the sintered layer 10 and the normal conduction electromagnets 1 to 3 so that the application of an excessive attraction force on the sintered layer 10 may be avoided, which makes it possible to maintain the attraction force at a desired value.
