A high-voltage element (H)to which a high gate voltage is applied, and a low-voltage element (L) to which a low gate voltage is applied, are formed in a semiconductor substrate (,). Bird's beaks (,) are formed in gate insulating films (,) by thermal oxidation. Since a gate electrode (,) of the element (H) has a shorter gate length than a gate electrode (,) of the element (L), the ratio of the bird's beak in the gate insulating films (,) is small in the element (L) and large in the element (H). Therefore, the element (H) has a high breakdown voltage and less aged deterioration, leading to long lifetime. The element (L) has a high current driving capability to produce high-speed operation. Thus, long lifetime, high operation speed and easy manufacturing steps are realized at the same time.

Semiconductor device and manufacturing method thereof

An aircraft control system which assist in determining aircraft arrival orders and intervals, reduces controller's workloads, and ensures safe aircraft flight operation are provided. An aircraft position display system provided as part of a terminal flight control apparatus for controlling the operation of an airport terminal with the use of radar and so forth employs a plurality of tags, each displaying on a first display screen a flight control instruction composed of heading data, altitude data, and speed data, a change arrangement for allowing a user to change the heading data, altitude data, and/or speed data of the tag independently according to the flight control instruction, a display arrangement for use in a flight control instruction input mode, an arrangement for blinking an entered flight control instruction until a pilot acknowledges the instruction, an arrangement for returning the mode to the original mode when the pilot acknowledges the instruction, and an arrangement for registering final approach FIX (F) data.

Aircraft control system

An individual guidance system for aircraft in an approach control area under automatic dependent surveillance which, by supplying the pilot with the required flight data automatically in units of micro air spaces, permits safe and accurate flight with little scope for human error, being an individual guidance system for aircraft in an approach control area under automatic dependent surveillance wherein the air-traffic control system divides the approach control area automatically into a group of micro air spaces, and establishes flight rules within the micro air spaces in order to guide aircraft by establishing no-fly air spaces. Then, at such time as a change has occurred in weather conditions or other data within the approach control area, it establishes in real time in the micro air spaces flight rules, estimated time of landing of the aircraft, estimated time when the aircraft will leave the approach control area and other data in such a manner as to reflect those details, and transmits the flight rules automatically to the system of a given aircraft when the aircraft reaches a position which corresponds to the micro air spaces. The air-traffic control system guides the aircraft in question in accordance with the flight rules which it has transmitted to the system of the aircraft, and the pilot pilots the aircraft.

Individual guidance system for aircraft in an approach control area

A flight control system user interface apparatus and a control data display method thereof are provided to reduce a workload on a controller and to increase the safety of flight. A main-control terminal on a man-machine interface apparatus for use in a flight control system has an aircraft position display area 102, an aircraft order display area 102, a simple strip display area 104, an aircraft data display area 104, and a control pilot data link communication display area. These areas are arranged in such a way that they are controlled by one input unit.
