Title: Directionally compositing method for conformal array antenna and medium storing the method
Inventor: OKI YOSHIAKI
IPC: G06N3/00
Filed: 1997-06-03
Abstract: PROBLEM TO BE SOLVED: To facilitate and accelerate the directional synthesization of antenna elements which are arranged under various conditions by generating information of a random bit string from feeding a voltage and phase and continuously performing a procedure in which a bit string of the next generation is generated, according to a genetic algorithm until feeding voltage and phase which are shown by information of a bit string of the next generation. SOLUTION: Spaces in which the number and arrangement of antennas and the intensity and phase, etc., of voltage of a feeding point are represented by numeral values are phenomenal spaces, and spaces in which a phenomenological space is represented by a character string are a gene space. A gene space generates the next generation by performing processing, such as mating, mutation and infection and makes it quantitative. When the next generation that is made quantitative does not meet a prescribed condition, the phenomenal space converts in into a bit string in a gene space based on excitation amplitude that shows the intensity of feeding voltage of an antenna and phase and repeats this operation until a next generation which satisfies the condition is found. Thereby, directional composting of antenna elements is easily and also fast performed.

Title: Reversible thermal recording medium
Inventor: FURUYA HIROMI
IPC: B41M5/337
Filed: 1997-05-20
Abstract: PROBLEM TO BE SOLVED: To prevent a recording medium from being dented even when it is used repeatedly by adding a resin in a crosslinking state, an organic pigment and/or an inorganic pigment to a reversible thermal recording layer. SOLUTION: The incidence of breakage in a coating due to the high frequency of printing and erasing is highest in a reversible thermal recording layer. Therefore, a resin in a crosslinking state, an organic pigment ant/or an inorganic pigment are added to the reversible thermal recording layer. To add the resin in a crosslinking state to the reversible thermal recording layer, a monomer, an oligomer and/or a polymer compound which cause a crosslinking setting reaction under the effect of various types of energy such as thermal energy, are used. These materials are, for example, a combination of a crosslinking agent and the resin having an active group which chemically reacts with the crosslinking agent. Further, the resin is one which can be crosslinked and cured by heat. Thus it is possible to enhance the heat-resistant strength and the heat matching properties of the recording layer with a thermal head and therefore, increase the durability against repeated us of the layer.
