Title: Method and device for preventing agc ringing of amplifier
Inventor: AOKI HIDEO
IPC: H03G5/16
Filed: 1993-04-15
Abstract: PURPOSE:To prevent the generation of ringing of an AGC circuit by regulating the amplifier so as to increase a time constant of an AGC circuit system when a level change in an output signal of an amplifier circuit is large and to decrease the time constant of the AGC circuit system when the level change in the output signal of the amplifier circuit is small. CONSTITUTION:A detection means 10 is operated to decrease a potential at a point (a) when an output level increases. When the potential at the point (a) decreases, while a capacitor C1 is charged through a resistor R1, a potential at a point (b) decreases and a transistor (TR)Q is turned on and a charge current flows through a resistor R3 to a point (c), then the speed of a potential change at the point (a) coupled directly with the point (c) slows down and the time constant of an AGC circuit system is changed. Thus, the AGC voltage at the point (c) or (a) applied to a control means 11 changes slowly and a level of an output signal chances slowly. Thus, no rinsing of an AGC voltage is caused and no ringing of an output signal level is caused.

IPC: H04N5/44
Filed: 1982-05-26
Abstract: PURPOSE:To erase transient sound from a speaker so that a listener may not feel unpleasantness, by making momentarily a diode conductive when turning off electric power source to make the 2nd transistor to be momentarily on state. CONSTITUTION:The titled device is constituted by connecting a collector of a transistor (TR) 7 and a base of a TR5 with a serial circuit composed by a diode 9 and resistor 10. If electric power source is turned off, the voltage of a terminal 6 suddenly becomes to be low level as shown in (a).

As a result, transient sound is not outputted from a speaker when turning off the electric power source.

Title: Film thickness measuring method
Inventor: MARUYAMA TAKASHI
IPC: G01B15/02
Filed: 1989-04-07
Abstract: PURPOSE:To measure the thickness of a film in an extremely small area by scanning the thin film stuck on a substrate with an electron beam probe and measuring the intensity of a characteristic X rays from electrons which are transmitted through the thin film to reach the substrate. CONSTITUTION:The resist film 2 on the Al substrate 3 is scanned with the extremely small electron beam probe 1 to measure the intensity of the characteristic X rays emitted by the substrate 3, and the quantity of variation in the characteristic X-ray intensity of the thin film part is converted into film thickness by using a calibration line which is generated previously. At this time, electrons are scattered in the resist to lose its energy, the number of electrons which reaches the substrate 3 corresponding to the film thickness is decreased, so the intensity of characteristic X rays generated by the substrate also decreases. Further, the probe 1 is fixed at a position to be measured and the acceleration voltage for the electrons is varied to find the film thickness from the acceleration voltage with which the characteristic X rays begin to be generated. Thus, the film thickness in the extremely small area can be measured.
