Title: Method for displaying multi-phase signal waveform
Inventor: DANIEL P TIM
IPC: G01R19/25
Filed: 1999-02-10
Abstract: PROBLEM TO BE SOLVED: To appropriately process to couple sample points particularly even when measured signals are multi-phase signals in a method for coupling and displaying the sample points of measured values obtained in an electronic measuring device or the like. SOLUTION: A threshold value is set for an inclination value between sample points to be coupled. Whether or not the inclination between two sample points exceeds the threshold value is studied (S206, NO). Only when the inclination does not exceed the threshold value, a coupling line is displayed between the sample points (S208). The coupling line is not displayed between sample points of an inclination exceeding the threshold value (S206, YES). In the same manner afterwards, the inclination value of succeeding sample points is compared with the threshold value, and whether or not the coupling line is to be displayed is judged.

Abstract: PURPOSE:To obtain a lettering guide facilitating the writing of alphabets and numerals, by providing a crosswise tie plate part of a predetermined width extending between a pair of longitudinal tie plate parts vertically to the longitudinal tie plate part, a horizontal index indicating a vertical position to the longitudinal tie plate part, and a longitudinal tie inclination index indicating a position inclined at a fixed angle to the longitudinal tie plate part. CONSTITUTION:A lettering guide 1 is provided with a top edge tie plate part 4 connecting the upper ends of a pair of longitudinal tie plate parts 3, 3 to each other and having the same width as the longitudinal tie plate part 3 and a crosswise tie plate part 5 laterally extending between the pair of longitudinal tie plate parts 3, 3 and having the same width as the tie plates 3, 4. A base 2a of a grasping board part 2 functions as a horizontal index to the longitudinal tie plate part 3. A cutout edge part 2b functions as a longitudinal tie inclination index to the longitudinal tie plate part 3. If a writing utensil moves along the edges of the longitudinal tie plate part 3 and the crosswise tie plate part 5 and further along the semicircular edge of the top edge tie plate part 4, the straight lines and circularly curved lines of alphabets or numerals can be drawn. Furthermore, if a writing utensil moves along the edges from one longitudinal tie plate part 3 up to the top edge tie plate 4 and therefrom down to the other longitudinal tie plate part 3, a character of U can be easily drawn.

Title: Jitter absorbing circuit
Inventor: ITOI TETSUSHI
IPC: H04L7/00
Filed: 1984-02-24
Abstract: PURPOSE:To absorb jitter simultaneously with a deinterleaving operation by using the margin of a memory space of a deinterleave memory. CONSTITUTION:An input reference address RA01 is varied relatively with respect to an output reference address RA00 if an input frame synchronizing signal is varied with respect to time. However, if the address RA01 is within the range of RA00-(RA00+127), jitter is absorbed because input data does not occupy the same address as output data. The address RA01 is changed forcibly to RA00+64 only when it exceeds this range, and the difference between addresses RA01 and RA00 is set to 64. Consequently, input data is addressed between the input address of the Nth symbol and the output address of the (N+1)th symbol. Hereafter, as long as the address RA01 is varied from RA00 to RA00+127 with the center as RA00+64, jitter is absorbed though the input frame synchronizing signal has jitter.

Title: Optical waveguide
Inventor: HIRUMA TAKEYUKI
IPC: G02B6/136
Filed: 1983-03-02
Abstract: PURPOSE:To improve coupling efficiency between an optical fiber and a light integrated circuit and to reduce transmission loss due to bending of a waveguide by forming a film consisting of an optical material having higher refractive index than that of a substrate on the substrate and forming a rib with a circular section on the film. CONSTITUTION:If the dispersion angle of ion beams is phi, etching of the substrate 1 shown in the figure (a) for a fixed period forms a rectangular rib shown in the figure (b). Since dynamical strength is deteriorated at the edge part of a mask 3', the part is fast etched and a taper is formed. The ion beams are made incident to the tapered surface at an inclined angle, so that the etching rate is increased and a curved surface shown in the figure (c) is obtained. When the etching is continued moreover, a taper shown in the figure (d) is formed. A smoothly curved surface shown in the figure (e) is formed by dispersion of the ion beams, and if the etching is continued for a fixed time until the mask 3' is completely removed, a rib having a semicircular section of which diameter is L can be formed. Consequently, an optical waveguide improved at its coupling efficiency and reduced at its transmission loss due to bending of the waveguide can be formed.
