Title: Optical waveguide and its production
Inventor: ISHIDA KOUJI
IPC: G02B6/13
Filed: 1983-11-28
Abstract: PURPOSE:To manufacture an optical waveguide having an optional refractive index value and optional refractive index distribution by an extermely simple method by using an oxynitride film consisting of silicon oxide and nitrogen oxide as a part of a core or a clad. CONSTITUTION:The refractive index of the oxynitride film constituted of a mixed film of silicon oxide and a nitrogen oxide is suddenly reduced by guiding a small quantity of O2 gas. Therefore, the oxynitride film having an optional refractive index between the refractive index of SiO2 glass and that of an Si3N4 film can be formed by selecting the ratio of N2 to O2 in sputtering atmosphere. The sputtering condition of the oxynitride film is that the mixed gas of O2 and N2 having partial pressure allowing the refractive index of the obtained oxynitride film to be set up to a required value is used as the sputtering gas. Thus, the optical waveguide can be simply manufactured only by changing the composition of gas at the sputtering time in accordance with time passage even if its refractive index distribution has any value.

Title: Level display device
Inventor: WAKUI TETSUYA
IPC: G09G3/04
Filed: 1997-08-20
Abstract: PROBLEM TO BE SOLVED: To improve the degrees of freedom of design by inputing segment data serially from the outside, rewriting the stored data for them and arbitrarily setting the lighting level of each segment of a display device. SOLUTION: In a comparator 8, digital data inputted from an absolute value circuit 7 are compared with segment data which are successively inputted from a data selector 6. When the digital data are larger than the segment data, a signal indicating '1' is outputted to a counter 9. A number shown by count data outputted from the counter 9 becomes the number of segments turned on from a segment, corresponding to the lowest level to a segment corresponding to a high level. Since the larger the level of a signal inputted to an input terminal 1 is, the larger the number of segments turned on in the displayer 12 is, the display corresponding to the level shown by the signal inputted to the input terminal 1 can be executed.

Title: Phase difference measurement
Inventor: KUDO MAKOTO
IPC: G01R25/00
Filed: 1987-09-07
Abstract: PURPOSE:To detect a phase difference accurately, by determining zero cross time Tx and Ty of two analog signals while zero cross time Tz is determined for one thereof to compute a phase difference between the analog signals from the time Tx-Tz. CONSTITUTION:Input signals (x) and (y) are converted into digital from analog as indicated by 10 and 11 to be stored into RAMs 12 and 13. A CPU 15 first reads an amplitude data out of the RAM 12 to find a point of inverting the data and two amplitude data before and after the inversion are obtained to compute zero cross time Tx. Then, the CPU 15 further performs a reading out of the RAM 12 to find a point where the amplitude data turns to negative from positive value and the subsequent zero cross time Tz is computed while the time Tx is subtracted from the time Tz is computed while the time Tx is subtracted from the Tz to obtain a cycle Tw of the input signal (x). Then, the CPU 15 reads the amplitude data out of the RAM 13 to find a point where the polarity of the data inverts to compute zero cross time Ty before and after the inversion. Then, the CPU 15 performs a computation of (Tx-Ty)X360/ Tw to display 16 a phase difference in terms of angle. In this manner, the phase difference can be detected accurately.
