Title: Instrument for measuring light output of multiple optical fiber
Inventor: KAWASAKI HIROYUKI
IPC: G02B6/00
Filed: 1989-03-03
Abstract: PURPOSE:To shorten the time for gain adjustment, i.e. the time for measurement by making light for gain adjustment entering respective coated fibers, determining the data on an optimum gain and holding the same before light for measurement is made incident on the light incident side of the multiple optical fiber. CONSTITUTION:The light for gain adjustment is first made incident successively from a multi-channel light source 11 of an instantaneous stabilization type on the respective coated fibers at one end of the multiple optical fiber 2. The exit light is converted to an electric signal by a photoelectric converter element 31 on a photodetecting side and is inputted to a range selector amplifier 32. The data on the optimum gain is determined to attain the optimum level as the input signal to a measuring circuit for each of the respective coated fibers and is memorized in a microprocessor 34. The light for measurement is then made to enter successively into the respective coated fibers. The gain selection of the amplifier 32 is controlled by the data on the optimum gain of the processor 34 at this time and, therefore, ends in a short period of time. The time for the measurement is thus shortened as a whole.

Title: Testing method for transistor in balanced amplifier
Inventor: AONO YOSHITAMI
IPC: H03F3/60
Filed: 1980-04-22
Abstract: PURPOSE:To improve characteristics of a balanced amplifier by making one DC cutoff each between input terminals and output terminals of one hybrid and by making connections at the cutoffs after testing static characteristics of FET separately. CONSTITUTION:Between input terminals 91, and 92, and output terminals 93 and 94 of output-side hybrid 9, cutoffs 25 and 26 for DC disconnections are made, respectively. To test static characteristics of FET7' in the said state, input terminal 92 of hybrid 9 is connected to DC power source VD via lead line 23. Consequently, a current flows only to the the drain of FET7' and never flows to FET7 because of  the cuts. After the static characteristics of FET7' are tested, lead line 23 is connected to the input terminal of hybrid 9 to test static characteristics of FET7. After  those tests, connections at those cutoffs are made in terms of direct current and high  frequency to improve characteristics of the balanced amplifier.

IPC: H03F3/45
Filed: 1979-04-28
Abstract: PURPOSE:To enhance the characteristics of the unbalanced differential amplifying circuit by providing the diode forward to the drain of one FET in the differential amplifying circuit and also connecting the emitter of the next step transistor directly to the drain of the other FET each. CONSTITUTION:With application of the AC signal to the gate of FETQ1, gm/2X Vi=i1 and i2=-i1 flow to the drains of Q1 and Q2 each. Current i'/i1=RD1/RD2 is obtained for resistance RD2 when the current amplification factor is large enough for Q3, and at the same time emitter current ie=gm/2XVi(1+RD1/RD2) is obtained for Q3. And in case the drain DC current of Q1 and Q2 is sufficiently larger than the collector DC current of Q3, RD1 RD2 and i1'=i1 are satisfied, and thus the even- order distortion can negated almost completely. At this moment, the conductance is gm which is identical to the source-earthed one-step amplifier. And the steadiness is secured with voltage gain A=gmRL to ensure setting to the optional current value, and the steadiness is secured up to the DC region since gain A does not have the time constant.
