Filed: 1990-11-30
Abstract: PURPOSE:To avoid a drop in gate strength and an increase in source resistance by constituting the device from a slot for electrode isolation which is formed in the specified width in a gate electrode region and a slot for gate electrode which is formed in the specified depth in the slot for electrode isolation and by forming a gate electrode in the slot for gate electrode. CONSTITUTION:With a first layer 22 and a second layer 24 as a mask, the first recess etching of an n<+>-GaAs layer 14 is conducted using H2SO4+H2O2 to form a slot for gate electrode 26. After receding the first layer 22 more than the width of the slot for gate electrode 26, the second recess etching is conducted using H2SO4+H2O2 to form a slot for electrode isolation in the n<+>- GaAs layer 14. By isolating a gate electrode from the n<+>-GaAs layer 14 and forming the gate electrode with the help of these two slots, both a drop in gate strength and an increase in source resistance can be prevented. Lastly, a gate electrode 29 is formed in the slot for gate electrode 26 using the second layer 24 as a mask.

Title: Determination of three-dimensional position of satellite by measuring radio wave refractive index in atmospheric gas player and ionospheric layer
Inventor: KAWAMATA KENICHI
IPC: G01R29/08
Filed: 1993-12-07
Abstract: PURPOSE:To determine the three-dimensional position of a satellite by measuring the radio wave refractive indices in the atmospheric gas layer and the ionosphere. CONSTITUTION:A satellite is assumed to be located at point P at a certain time. When microwaves from the satellite located at the point P are received at an observation point located at point A, it appears as if the microwaves received were coming from a satellite located at point P1. Supposing that microwaves from a satellite located at the point P1 are received, the course of the microwaves supposed to be radiating from the point P1 is accurately followed to accurately calculate the radio wave propagation time from the point P1 to the point A, the distance between the point P1 and a horizontal plane passing the point A, and the cosine of the incidence angle of microwaves rushing into the interface between a layer in which radio waves rectilinearly propagate and the ionosphere. Next, the microwave refractive index of each of parallel plane layers calculated according to the U.S.A. standard atmosphere is given as the initial value of the microwave refractive index of each parallel plane layer. Then, the true value of the microwave refractive index of each of the adjacent parallel plane layers is calculated.

Title: Communication connecting method
Inventor: TACHIBANA SHIGEO
IPC: G06F13/00
Filed: 1993-12-08
Abstract: PURPOSE:To make a communication connection under optimum conditions by managing a call-back time zone on a client side and informing a server of whether or not call-back operation is performed on the basis of communication connection request time when a communication connection request is generated. CONSTITUTION:The client 10 once receiving a service request such as an information retrieval request finds the telephone number of the server 20 which offers the service. Then the call-back time zone corresponding to the server is retrieved in a communication path optimization table 13a and the current time is checked to decided whether or not the current time is within the call- back time zone. When it is decided that the current time is in the call-back time zone, a call-back request is made after a communication connection with the server 20 is made. Then the server 20 or client 10 disconnects the communication and a communication connection request from the server 20 is expected. When a new connection is made by the server 20, the client 10 makes an information retrieval request. Unless it is decided that the current time is not in the call-back time zone, the retrieval request is made as it is.

Title: Image encoder and image decoder
Inventor: SUMINO SHINYA
IPC: H04N19/91
Filed: 1993-12-08
Abstract: PURPOSE:To heighten encoding efficiency in image encoding and image decoding. CONSTITUTION:Frequency conversion and blocking are applied to an input image signal 1 by a spatial/frequency converter 2, and it is quantized. The re-arrangement of a quantization value 5 with different orders is performed by scan converters 6a-6c. Re-arranged quantization values 7a-7c are inputted to encoding quarvtity calculators 8a-8c, respectively, and encoding quantity 9a-9c when variable length encoding is performed are calculated. A comparator 10 compares the encoding quantity 9a-9c, and outputs the scan converter in which the encoding quantity can be minimized as a selection value 11. The selection value 11 is accumulated in memory 12 transiently. While, a selector 14 reads out the selection value 11 calculated by an adjacent encoded block from the memory 12, and selects the quantization value of the scan converter shown in the value, and outputs it as a quantization value 15. The quantization value 15 is sent out by variable-length encoding by an encoder 16.

Filed: 1993-12-13
Abstract: PURPOSE:To efficiently overlap sets of image information by displaying image information located above for the overlapping in a translucent way and viewing image information located under so as to confirm the relation of position of the image information sets. CONSTITUTION:A mixer section 14 mixes data read from a character data VRAM 10, a graphic data VRAM 11, and a natural image data VRAM 12 and provides the mixed signal as an output. In this case, the usual mode or the image forming mode is selected based on a control signal Sc outputted from a CPU 6 by the mixing section 14. In the image forming mode, each level of character data, graphic data and natural image data is halved and the character data and the graphic data are added to the natural image data. Thus, the data are processed as translucent data and the natural image in the lower position is observed. Thus, the position of characters and graphics is simply decided for a natural image and the efficiency of overlapping is improved.
