IPC: G02F1/025
Filed: 1984-06-07
Abstract: PURPOSE:To control the propagating state of light by the intensity or wavelength of incident light by constituting optical waveguide parts of >=2 kinds of materials having different forbidden band widths. CONSTITUTION:The two optical waveguides 9 are formed on a GaxAl1-xAs clad layer 8 on a GaAs substrate 7, i.e., one optical waveguide is formed of a Gay Al1-yAs layer 10 and the other optical waveguide is formed of a GayAl1-yAs layer 11 and a GazAl1-zAs layer 12. The thicknesses of the layers 8, 10-12 are respectively 2, 1.5, 1 and 0.5mum. The width of the optical waveguides A, B is made 2mum and the spacing therebetween is made 3mum. The incident light is absorbed by the layer 12 according to the intensity of the light input and the number of the generated carriers changes when the light having photo energy larger than the forbidden band width of the layer 12 is made incident on the optical waveguide part A. The propagation constant of the optical waveguide is thereby changed and therefore the coupling state of the two optical waveguides A, B changes and the intensities of the light outputs at the exit ends of the two waveguides A, B behave respectively as shown by the curves in the figure.

Filed: 1987-05-14
Abstract: PURPOSE:To reduce the effect of X-ray scattering due to an object to be examined even when there is a distance between the substance to be examined and a film and to perform stable X-ray photographing, by mounting a bottom surface member having a punched part at the principal part of the bottom surface of a standard substance and expanding to the periphery of the standard substance.

The bottom surface member has a punched part at least at the principal part of the bottom part of the standard substance and expands to the periphery of said standard substance. For example, when an alumi num staircase or slope is placed to the crotch to take the X-ray images of left and right femoral parts, the bottom surface of the aluminum staircase or slope is surrounded by a metal plate 1 having a punched part 2 for projecting X-rays only at the part where the standard substance is placed. By this method, a stable X-ray image is obtained with respect to an object to be examined easy to generate X-ray scattering at the time of X-ray photographing using the substance such as the alumi num staircase or slope.

Title: Optical input signal interruption detector
Inventor: SUDA ATSUSHI
IPC: H04B3/46
Filed: 1992-05-08
Abstract: PURPOSE:To surely detect interruption of an input signal by passing a demodulation output from a light receiving element through filters whose pass frequency band width differs and detecting an optical input signal interruption based on a ratio of a peak level with respect to the signal passing through the filter. CONSTITUTION:A signal demodulated by a light receiving element passes through a 1st filter 1 and a 2nd filter 2 whose pass band width differs and a 1st peak detector 3 and a 2nd peak detector 4 latch and detect the peak levels respectively. An input interruption detector 5 compares the peak levels detected by the detectors 3, 4 and detects and outputs the optical input signal interruption based on the ratio of them. That is, even when the characteristic of the light receiving element demodulating the optical signal is changed due to temperature or the like, the ratio of noise power passing through the filters 1, 2 is unchanged. Thus, the change in the amplitude of the demodulated digital signal is obtained as the ratio of the detected levels at the detectors 3, 4 by the detector 5 and the detector 5 detects the optical input signal interruption based on the ratio.
