Title: Monitoring control system for optical repeater
Inventor: YAMAMOTO SHU
IPC: H04B10/032
Filed: 1988-10-28
Abstract: PURPOSE:To keep the gain of a semiconductor light amplifier used in an optical repeater by modulating the intensity of signal light with a modulation index less than a signal bit rate frequency by a sine wave of low frequency, and using the signal as a control monitoring signal. CONSTITUTION:An optical demultiplexing circuit 2 demultiplexes the partial demultiplex light L3 of output amplification light L2 from the semiconductor light amplifier, and an optical/electrical (O/E) conversion circuit 4 outputs to convert it to an electrical signal S1. The amplification light L2 outputted from the light amplifier 2 is comprised of amplified signal light and natural emission light L0 which becomes noise light generated from the semiconductor light amplifier 2. The intensity of the amplified signal light is modulated by the sine wave of low frequency, however, no modulation is applied on the natural emission light L0. Therefore, the output signal S2 of a filter 5 is obtained as the sine wave for control in proportion to the signal light L1. The gain can be kept constant by detecting the fluctuation of the gain of the semiconductor light amplifier 2 from the fluctuation of the output signal S2 of the filter 5, and controlling an injection current Ii by an amplifier driving circuit 7 receiving a driving control signal S3 from an automatic gain control(AGC) circuit 6 so as to keep the level of the sine wave constant.

Title: Semiconductor device and manufacture thereof
Inventor: SAITOU MITSUCHIKA
IPC: H01L29/78
Filed: 1986-11-14
Abstract: PURPOSE:To improve reliability in proportion to a decrease in yielding amount of hot carriers without obstructing miniaturization, by covering low- concentration, third impurity diffused layers having shallower diffusion depth than second impurity diffused layers and in contact with the second impurity diffused layers, which act as a drain region with a gate electrode completely. CONSTITUTION:N<+> type impurity diffused layers 19 and 20 are formed on the main surface of a P-type silicon substrate 18 with a specified interval being provided. N<-> type impurity diffused layers 21 and 22, whose diffusing depth is shallower than the impurity diffused layers 19 and 20 and impurity concentration is lower, are formed on the main surface of the substrate 18 between both layers so as to contact the diffused layers 19 and 20. A gate electrode 24 is formed on the silicon substrate 18 between the impurity diffused layers 19 and 20 by way of a gate insulating film 23 so as to cover the impurity diffused layers 21 and 22 completely. Thus the yielding amount of hot carriers can be reduced, reliability is improved correspondingly and miniaturization is made possible.

Title: Interruption of adjustment mechanism
Inventor: SATO TADASHI
IPC: H01H85/04
Filed: 1988-10-26
Abstract: PURPOSE:To automate an operation and to make it efficient by a method wherein after prescribed adjustment is performed, a current exceeding an allowable current value of an internal fuse is made to flow therethrough from an external terminal, so as to melt the fuse. CONSTITUTION:In a state wherein microfuses 16a and 16b are connected between a mass balance adjustment mechanism 2 and external terminals 14a and 14b, a voltage or a current is supplied to the adjustment mechanism 2 from the external terminals 14a and 14b so as to correct mass unbalance around an output shaft 6. Subsequently, a current exceeding an allowable current value of the fuses 16a and 16b is made to flow therethrough between the external terminals 14a and 14b, so that the fuses 16a and 16b be melted. Although the current flows through a heater 2z of the mass balance adjustment mechanism 2 on the occasion, it flows only momentarily therethrough and therefore solder 2x is not melted again. Since the adjustment mechanism 2 is interrupted from the terminals 14a and 14b when the fuses 16a and 16b are melted, it does not happen that the solder 2x is melted again and, consequently, the mass unbalance occurs again around the corrected output shaft 6 even when a user connects an external circuit erroneously to the terminals 14a and 14b when he uses a gyro.

Title: Semiconductor device
Inventor: WASHIO KATSUYOSHI
IPC: H01L27/06
Filed: 1989-10-20
Abstract: PURPOSE:To arrange that an element of a high-speed operation can coexist with an element of a high breakdown strength by a method wherein, when a potential of a collector electrode is increased, a region of a single-crystal semiconductor layer sandwiched between an insulating film and a semiconductor is pinched off and a breakdown strength as viewed from the outside is increased. CONSTITUTION:An n<-> type epitaxial layer 3 sandwiched between an insulating film 101 and a p-type substrate 1 is formed in a region B between an n<+> type collector extraction region 6 and an active region A. The layer 3 has a MOS structure by a polycrystalline semiconductor layer 10 and the insulating film 101 in its upper part, and has a p-n junction to the p-type substrate 1 at its lower part. Thereby, when a potential of a collector electrode is increased, the layer 3 is pinched off. Consequently, a breakdown strength is increased. A breakdown strength between the layer 3 in the region B and the polycrystalline semiconductor layer 10 is a dielectric breakdown voltage of the insulating film 101; and a junction breakdown strength of the layer 3 to the p-type substrate 1 can be made to a sufficiently high value because a junction concentration of both is low. Even when a thickness of the layer 3 is made thin, a punchthrough is not caused in the pinch-off region B. Since a base region 4 exists only in the active region A, a high-speed operation of a high breakdown-strength transistor can be realized.
