Title: Frequency synthesizer with phase locked loop
Inventor: ITO KENJI
IPC: H03L7/187
Filed: 1987-05-30
Abstract: PURPOSE:To obtain a PLL frequency synthesizer obtaining a now noise characteristic by switching the gain of a loop filter in response to the order of frequency-division even when the ratio of an upper limit Nmax and a lower limit Nmin of the output frequency of a synthesizer is large. CONSTITUTION:In inputting 2 control signal selectively to control signal input terminals 15a-15d, an optional resistor in resistors 9a-9d is selected and connected in parallel with a resistor 5. In assuming a resistance between the active filter 3 and the resistor 5 as R'1, when the value R'1 is selected to suppress the change in the open loop gain due to the change in the frequency division order N to bring the open loop gain to be Gaf at all times, a low noise PLL frequency synthesizer output is obtained. The open loop gain Gaf is denoted by equation I, and switches 12a-12d are subject to switch control selectively by using an external control signal so as to satisfy equation II by the resistance R'1 with respect to the frequency division degree N. As a result, the open loop gain is always selected to be Gaf to extract a low noise output over a broad band.

Title: Video processing system
Inventor: KITA KOUSHIROU
IPC: H04N7/18
Filed: 1980-09-30
Abstract: PURPOSE:To ensure the correct decision for a target with a small number of elements, by supplying a video signal into a comparator via the 1st and 2nd integrators and then comparing it with the target detecting threshold level to detect the target. CONSTITUTION:The radar video signal supplied from a radar receiver is supplied to an A/D converter 20 via an amplifier 10. The digital video signal, i.g., the output of the converter 20 receives an addition of all subrange bins in the same range bin by the 1st integrator 30 of the next stage to be sent to the 2nd integrator 70. The integrator 70 gives a PRT integration to the subrange bin groups added in a range bin section with each equal range bin. Then the value of the noize range bin is subtracted through a subtractor 76 and delivered to a comparator 60 of the next stage. If this value exceeds the target detecting threshold level, it is furthermore delivered to a target detector of the next stage for the final target detection. In such way, a large number of registers are eliminated to ensure the correct decision for a target with a small number of elements.

IPC: H01L29/872
Filed: 1984-07-03
Abstract: PURPOSE:To lower the resistance of a Schottky gate electrode while obtaining a semiconductor device having excellent Schottky characteristics and controllability of characteristics by constituting the Schottky gate electrode by a high melting-point metallic film and a high melting-point metallic silicide. CONSTITUTION:A Schottky gate electrode 5 is constituted by films such as a W film 3a and a W0.34Si0.66 film 4a. Consequently, not only the Schottky characteristics of a GaAs MESFET are improved extremely but also the inter-surface uniformity and reproducibility of Schottky characteristics are enhanced, and the resistance of the Schottky gate electrode 5 is lowered. Since the thickness of the W film 3a is reduced, adhesive properties to a GaAs substrate 1 of the W film 3a are improved, thus resulting in no peeling of the Schottky gate electrode 5 through annealing. The W0.34Si0.66 film 4a has high chemical resistance and oxidation resistance, thus resulting in no limitation to processing such as etching and a heat treatment process.
