IPC: G02F3/00
Filed: 1986-07-24
Abstract: PURPOSE:To obtain an optical logical element having a wide allowable wavelength range of input light, by providing a semiconductor whose refractive index in the vicinity of an absorption end is varied by the intensity of incident light, using a light beam of a shorter wavelength side than its absorption end, as control light, and switching an optical path of signal light in a longer wavelength side than the control light, by a variation of the refractive index. CONSTITUTION:For instance, waveguides 12, 13 of 10mum interval, 20mum width, and 1.7mm length are formed on an InP substrate 11, and the wavelength of an absorption end of a core part of the waveguides 12, 13 is set to 1.30mum. Signal light 2 of 1.31mum wavelength, and control light 3 of 1.29mum wavelength are made incident on an input terminal 14 of a directional coupler 1, and an input terminal 15, respectively. When the control light 3 whose wavelength is short is made incident, a refractive index of the waveguide 13 is varied, an electric field distribution of the signal light 2 is deviated to the waveguide 13, and the signal light 2 appears in an output terminal 17. The control light 3 does not appear in the output terminal since its absorption in the waveguide is large. After all, when a state of the signal light 2 and a state of the control light 3 are denoted as S and C, respectively, output light 4 for showing a logical operation of S and C is obtained from an output terminal 16, and output light 5 for showing a logical operation of S and C is obtained from an output terminal 17.

In this water resistant pan 3, a floor surface is covered with tiles 10. Each rising piece 11 is installed in four corner edges of this water resistant pan 3. Among these four corner edges, in two-side parts along the circumference of the PC floor block 1, a wall panel mounting part 12 is provided toward the outside from an upper end of this rising piece 11, and a wall panel 13 is erected on it. Likewise two anchor pieces 17, 25 are installed in the pan 3. Accordingly, since the backside of the pan 3 is embedded in the concrete floor block body, it is excellent in water resistance. Durability in this waterproofness is very good as well. As it is produced at a factory, execution workload at a construction site is very few. Since the backside of the pan 3 is embedded in the floor block body 2, floor height (stamping height) of the pan 3 is low. In addition, the extent of effective thickness in the precast concrete block 1 is enlargeable. Moreover, owing to an anchor, a bonding property between the water resistant pan 3 and the floor block body 2 comes to being high.

Title: Digital type floating threshold value generating circuit
Inventor: SUDA TADASHI
IPC: G06T5/00
Filed: 1983-09-26
Abstract: PURPOSE:To eliminate the time difference between an input signal and a threshold value and remove an unnecessary-level signal securely by calculating the threshold value by using the mean value of multilevel digitized signals and the maximum value among N digital signals. CONSTITUTION:A waveform (a) consisting of only a signal with an unnecessary level is requested not to be outputted as a binary signal. This request is represented as an inequality 1 (Esh: threshold value at t3) by paying attention to time t3. Then, a threshold value Esh' (Emin: minimum value of ej) is generated one after another according to equations 2 and 3. Further, when Esh'=e3 as shown in a figure, Esh' is often not determined as the threshold value. In this case, alpha shown in an equation 5 is only introduced so that the inequality 1 holds all the time. For the purpose, the technique of the threshold value generation shown by the equation 5 is employed to eliminate the time difference between the input signal and threshold value, removing the signal with the unnecessary level securely.
