Title: High frequency amplifier
Inventor: MURAGUCHI MASAHIRO
IPC: H01P1/212
Filed: 1990-03-27
Abstract: PURPOSE:To miniaturize a high frequency amplifier by forming a 2nd harmonic wave blocking stub connecting to an output terminal of an amplifier device of a high frequency amplifier, opened to a fundamental wave and short-circuited to a 2nd harmonic wave with a high frequency transmission line and a capacitor located to a specific position of the high frequency transmission line. CONSTITUTION:A high frequency transmission line 15 whose electric length is 2theta (0<theta<90 deg.) is connected to a drain of a FET 12 as a 2nd harmonic wave blocking stub. Then its connecting point is connected to ground via a capacitor 16 whose capacitance is C1 and the midpoint of the high frequency transmission line 15 is connected to ground via a capacitor 17 whose capacitance is 2C1. Then each parameter is set so as to satisfy equations Z=Z0/sintheta and C1= costheta/2pifZ0, where Z is a characteristic impedance of the high frequency transmission line 15 and Z0 is a characteristic impedance of the high frequency transmission line 15 with respect to a conventional length of a 2nd harmonic wave (wavelength is a half). Thus, the similar characteristic to that of a conventional 2nd harmonic wave blocking stub using a high frequency transmission line whose length is equivalent to a half wavelength and double frequency is obtained.

IPC: C03B20/00
Filed: 1993-04-06
Abstract: PURPOSE:To reduce the generation of bubbles by heat-treating a transparently vitrified optical fiber preform in a high vacuum atmosphere within a specific temp. range.

Abstract: PURPOSE:To detect operation contradicting an instruction by tracing a change in a control signal generated in the inside of a magnetic recorder itself and sending the traced information to a master device. CONSTITUTION:A tracing part 6 is controlled by a control signal 17 outputted from an interface processing part (IF) 3 and executes tracing operation. At the time of receiving an R/W instruction and starting an R/W control part 4, the IF 3 initializes the tracing part 6 by the control signal 17, and at the end of operation, refers tracing information 18 together with end information 15, integrates the tracing information 18 in the end code 16, and sends the integrated information. Namely, the tracing information 18 for transmitting practical operating status is sent to the master device 1 independently of the end information 15 obtained by deciding the validity/invalidity of operation by the R/W control part 4. Even when data are erased instead of its writing, a different end code 16 is outputted because the format of the control signal 13 is different between data writing and erasing and a control signal tracing result for distinguishing each format is different in each format.
