Title: Production of grating element
Inventor: NISHIDA NAOKI
IPC: G02B6/122
Filed: 1998-03-31
Abstract: PROBLEM TO BE SOLVED: To obtain a producing method of a grating element having high coupling efficiency by which an interface grating can be produced with good accuracy. SOLUTION: In this producing method, a SiO2 film 16' is formed in the film thickness corresponding to the height of a desired grating (first thermal oxidation process). Then the SiO2 film 16' is patterned into a desired grating pattern by reactive ion etching. Then a SiO2 film 15 having the film thickness corresponding to the desired optical buffer layer is formed on the silicon substrate 10 (second thermal oxidation process). Thereby, a grating 16 is produced on the SiO2 film 15. Then ZnO is sputtered on the SiO2 film 15 to form the optical waveguide layer 20.

IPC: H04N5/202
Filed: 1991-04-18
Abstract: PURPOSE:To realize the gamma correction circuit by connecting plural series circuits each comprising a PN junction and a resistor turned on/off at a different input level in parallel and supplying a bias current to the PN junction of the series circuits turned on at the lowest input level. CONSTITUTION:Series circuits S0-Sn are diodes D0-Dn having the same temperature characteristic and the series circuits are connected in parallel, then a temperature change by the diodes is almost cancelled. Moreover, a reference voltage is obtained at a reference voltage terminal Tr in a series circuit Sr to obtain the reference voltage by selecting a resistor Rr and a current source Ir to be equal to a resistor R0 and a current I0 of the series circuit S0 deciding the initial slope. When the circuit is integrated especially, since a pair characteristic between diodes and resistors is excellent, the gamma correction curve with less and stable dispersion at all time is obtained as a difference voltage between the terminal Tr and an output terminal To.

Abstract: PURPOSE: To enable high speed operation processing simply, by setting the 2 n  notation in K-digit taking (n) as positive integer to dividend register, and performing division with 2 n -1 through the use of divider consisting of a plurality of adders.  
     CONSTITUTION: Taking (n) as a positive integer, 2 n  notation in K-digit shown in equation I is set to the dividend register REG. Next, the division is made with 2 n -1 by using the divider DIV consisting of the adder A 01  in 5-digit. That is, all the coefficients of 2 n  notation are added, and if the content carry in excess of the lower n-digit as the result of addition is not 0, it is repeated until the carry is 0, and the carry as the result of addition and the content of lower n-digit are added. Next, if the result equals to 2 n -1, the carry is 1 and the residual is made to 0. If not equal, all 1 detection in which the carry is made to 0 and the result of addition is taken as the residual, is made. Thus, the division by 2 n -1 can be made in high speed through simple addition.
