Title: Pulse re-forming apparatus
IPC: H03K6/00
Filed: 1964-01-02
Abstract: 1,025,585. Diode and transistor pulse shaping circuits. RADIO CORPORATION OF AMERICA. Jan. 2, 1964. [Jan. 23, 1963], No. 267/64. Headings H3P and H3T. A pulse shaping circuit comprises an amplifier the output of which is coupled via a capacitor to a pair of shunt diodes of opposite polarity. Fig. 4 shows an amplifier for reshaping and distributing television synchronizing pulses. The negative-going pulses at terminal 51 are amplified by transistor 52 and passed via complementary symmentry emitter followers 74, 76 to a shaping circuit comprising capacitor 32<SP>1</SP> and diodes 34<SP>1</SP>, 36<SP>1</SP>. Junction 33<SP>1</SP> is initially at - 9À1 v. so that the leading corner 43 (Fig. 3) is passed by capacitor 32<SP>1</SP> until the voltage at 33<SP>1</SP> reaches earth potential when diode 34<SP>1</SP> becomes conductive, charging capacitor 32<SP>1</SP> via the NPN transistor 74. The voltage at 33<SP>1</SP> remains at earth potential until the arrival of the leading corner 47 (Fig. 3) of the input pulse when the junction 33<SP>1</SP> begins to follow the trailing edge of the input waveform 42. Diode 36<SP>1</SP> becomes conductive when the junction 33<SP>1</SP> reaches the potential of the Zener diode 90 (9À1 v.) when capacitor 32<SP>1</SP> discharges via the PNP transistor 76. The pulse 111 at junction 33<SP>1</SP> is thus a lower amplitude version of the pulse 42 but having reduced rise and fall times and retaining the duration between the leading corner 43 of the leading edge and the leading corner 47 of the trailing edge. The charge and discharge times of capacitor 32<SP>1</SP> are made shorter than the pulse duration so that diodes 34<SP>1</SP>, 36<SP>1</SP> are initially non-conductive at the onset and offset of the input pulse hence charge storage effects are avoided. Drift in potential at junction 33<SP>1</SP> due to base current during the interpulse period is minimized by a bias current supplied via resistor 91. A switch 93 is opened when the circuit is used with lower frequency (vertical) drive pulses so as to increase the resistance in the base current compensating circuit. The pulses 111 are passed via an emitter follower 88 to a clipping circuit comprising diodes 101, 102 which remove 10% from the positive and negative extremities, the resultant pulses being amplified by transistors 103, 105 and passed via emitter followers 106, 107 to separate output terminals. The circuit is protected against over voltage inputs by diodes 56, 57 and Zener diode 59. A T-section filter comprising inductors 53, 58 minimizes the effect of the input capacitance. Amplifying transistor 52 is provided with a peaking inductor 72 and peaking capacitor 62.

Title: Ultrasonic microscope
Inventor: ISHIKAWA KIYOSHI
IPC: G01N29/06
Filed: 1982-01-06
Abstract: PURPOSE:To improve the reliability, by incorporating an ultrasonic microscope in a production line for supporting a sample without contact, introducing a liquid or gas from both sides of a running sample so that it is useful for an intermediate inspection of the material production. CONSTITUTION:A sample 14 is led into a sample holding part 16 through a guide rolls 15. Into the sample holding part 16, a liquid 17 which is an ultrasonic propagating medium is adjusted to some pressure and is discharged from a discharge port 18, therefore, the sample 14 is supported stably without contact in the holding part 16 by its static pressure, and moves smoothly. When an ultrasonic beam is irradiated from a spherical lens 1 provided on its upper part, to the sample 14 supported in this way, the liquid 17 between the spherical lens 1 and the sample 14 executes the same operation as the ultrasonic propagating medium, therefore, ultrasonic waves are propagated to the sample 14 surface without a trouble, and high resolution is obtained.
