Patent number: 5347612Abstract: After sampling a voice signal by a microphone (31), a voice interval is detected by a voice interval detector (32). Then, the voice signal is processed by a frequency analyzer (33) having a predetermined number of channels at a predetermined time interval, whereby a corresponding portion of the voice signal is quantized at each channel. Then, quantized data obtained from these channels are binary converted (34) to thereby form a frame comprised of a series of binary data. Each data of this frame corresponds to one of the channels, and preferably it is set to be an integral multiple of a computer calculation unit (e.g., 4 bits, 8 bits, etc.). When forming a combination frame by superimposing two or more of such frames, the combination frame is divided into layers, whereby it is so structured that each bit is represented by a binary number in each layer.Type: GrantFiled: July 16, 1990Date of Patent: September 13, 1994Assignee: Ricoh Company, Ltd.Inventors: Junichiroh Fujimoto, Seigo Yasuda, Tomofumi Nakatani

Patent number: 5345546Abstract: A 3-dimensional (3-D) Computer Aided Design (CAD) System generates a fillet surface which smoothly connects two surfaces to each other. This is accomplished by sliding a circle on a normal plane of a user-designated spine curve which is in contact with two surfaces. Then, the fillet surface is approximated by Gregory patches which are generated from trajectories of two tangent points between the circle and the two surfaces. The fillet surface thus expressed by the Gregory patches is easily and efficiently processed in computers such as those in 3D CAD systems. Because the fillet surface is generated along the spine curve, various fillet surfaces, including that generated by the conventional rolling-ball blending method, can be generated to satisfy various needs of designers of 3-D CAD Systems.Type: GrantFiled: December 19, 1991Date of Patent: September 6, 1994Assignee: Ricoh Company, Ltd.Inventors: Tsuyoshi Harada, Kouichi Konno
