Patent JP-H06244646-A (JP)
Title: Amplifier circuit
Inventor: MIYAKE HIDEKI
IPC: H03G3/00
Filed: 1993-02-19
Abstract: PURPOSE:To obtain a variable gain amplifier circuit large in an operating signal even when a power supply potential is low. CONSTITUTION:Signals (VA, VC) and (VB, VD) obtained by adding first and second different bias to differential input signals are respectively applied to a pair of transistors 1 and 3 and a pair of transistors 2 and 4. Then, both of pairs perform differential operations corresponding to the applied signals. On the other hand, a pair of transistors 1 and 2 and a pair of transistors 3 and 4 divide one current applied to the respective pairs. Thus, differential output signals can be provided from a pair of transistors 2 and 4, and a gain is controlled corresponding to a current flowing through the transistors 1 and 3. Since the number of transistors to be connected in series is decreased for one in comparison with the conventional case, the signal to be operated is enlarged just for a saturated voltage between the collector and emitter of the transistor.

Abstract: PURPOSE:To prevent infiltration of water into the inner surface of a steel pipe, by a method wherein an ultrasonic wave is made incident from the surface of beveled worked part of a steel pipe to execute a lamination flaw detection to enable the identification in an apparatus with an ultrasonic detector mechanism section at a part other than the beveled part of the steel pipe. CONSTITUTION:An ultrasonic wave is made incident into the surface of a bevel- worked part 2 of a steel pipe from outside the steel pipe 1. The position of a probe 5 is so set as to meet an angle theta of refraction by a transverse wave. An ultrasonic beam 7 from the probe 5 is made incident into the surface of the bevel-worked part 2 at an angle beta of incidence and reflection to generate a surface echo. The beam 7 transmitted through the steel pipe 1 is reflected at a defect 8. In the case of lamination defect, the reflection surface of which is at the right angle to the direction of the beam 7 and parallel with an inner/ outer surface of the steel pipe, the beam 7 is received by the probe 5 in the same path as the direction of incidence and reflection of the beam 7 to obtain a defect echo (F). When there is no defect, the beam 7 propagating through the steel 1 is reflected on the inner surface 4 of the steel pipe to obtain a bottom surface echo (B).

Title: Measuring apparatus of film thickness
Inventor: TOKUMARU MAKOTO
IPC: G01B11/06
Filed: 1988-02-12
Abstract: PURPOSE:To measure the film thickness of a film to be measured without depending on the transmission of light, by measuring the film thickness on the basis of a time or reception of a coherent light. CONSTITUTION:A magnetic tape 1 is made to run by rotating a rotary body 2. A laser light from a laser light source 12 is scanned by driving a scanning mechanism 14 and the laser light passing through a gap between a light intercepting plate 15 and the magnetic tape 1 is sensed by a photosensor 15. A threshold value circuit 16 determines a mean value of an output of the photosensor 15 on the occasion when the laser light passes completely and of an output thereof on the occasion when the laser light is intercepted completely. A comparator 17 subjects the output of the photosensor 15 to wave-shaping with this mean value used as a threshold value, and a counter 18 counts the pulse width of this output and outputs a count value thereof to an arithmetic circuit 3. By a scanning mechanism 24, a photosensor 25 and a counter 28, a pulse width is counted quite in the same way. Using the count values of the two pulse widths, the arithmetic circuit 3 computes the film thickness of the magnetic tape 1, and a display circuit 4 displays a value of this film thickness.
