Title: Schottky barrier semiconductor device
Inventor: IMAI YASUO
IPC: H01L29/861
Filed: 1986-03-05
Abstract: PURPOSE:To prevent barrier metals from peeling off by a method wherein the surface of a compound semiconductor is intermittently coated with insulating films to be alternately positioned with parts not coated with the same while said parts are continuously coated with a metallic layer to form Schottky barriers on the parts whereon the parts not coated with the insulating films are in contact with the metallic layer. CONSTITUTION:An N-type GaAs region 2 is epitaxially grown to form a substrate 3 on an N<+> type GaAs region 1. Insulating films 4 comprising silicon nitride film (Si3N4) are formed on a part of the surface of N-type region 2. The insulating films 4 produced by CVD process are formed into specified patterns by photoetching process. Furthermore, a metallic layer 6 comprising Al is formed by evaporation on overall upper surface into rectangular shape a little smaller than the entire surface of insulating films 4. The metallic layer 6 forms Schottky barriers on the boundaries on the N-type GaAs region 2 at respective openings 5. On the other hand, an electrode 7 is formed on the backside of N<+> type GaAs region 1 in low resistance contact therewith. The electrode 7 is formed by vapor deposition of Au-Ge alloy and Ni in order.

Title: Radar target detecting circuit
Inventor: YASUFUKU MASAKI
IPC: G01S7/32
Filed: 1990-02-26
Abstract: PURPOSE:To reduce degrading of target detection performance caused by a clutter outside the detecting range of targets by adding a circuit to replace an amplitude of a cell outside the target detection range with the amplitude of a cell in proximity to the target detection range. CONSTITUTION:A replacement circuit 4 replaces amplitude values of two cells of F-3 and F-4 with the amplitude value of cell F-2 located at the second place to the outside from the lower limit F0 of a target detection range. When a target and a clutter signal are inputted into a Constant False Alarm Rate (CFAR) detection circuit 5, the amplitude values of the cells of F-3 and F-4 are replaced with the amplitude value of the F-2 so that the mean of clutters outside the target detection range becomes smaller to reduce a detection threshold, which improves detection performance within the clutter. In other words, since the clutter which grows in amplitude as it is farther from the target detection range is replaced with the clutter which is in proximity to the target detection range, degrading can be reduced in the detection performance within the clutter of the target as caused by the clutter outside the target detection range.

Abstract: PURPOSE:To enable to hold the line polarity at the same polarity for the time designated, by providing the delay circuit between the character transmission circuit and the control circuit. CONSTITUTION:The delay circuit 2 is provided between the character transmission circuit 1 and the control circuit 3. When the holding of polarity for a given time is required for the circuit 3 after transmission of character, the transmission character is transferred on the transmission data tranfer line 5, the line polarity after character transmission is designated with the holding polarity indicating signal line 4 and the delay time to the circuit 2 is designated with the delay time set signal line 6, allowing the circuit 1 to be held to the designated polarity after character transmission. Further, the circuit 2 delays the processing request signal from the circuit 1 in the designated time with the circuit 3 and transfers it to the circuit 3. Since the circuit 3 processes the processing request signal trasferred with a delay like this for the next character signal immediately, the polarity hold for a given time after character transmission can be made.
