Title: Method and apparatus for detecting deformation of wall face
Inventor: SADO TETSUO
IPC: G01B15/00
Filed: 1997-03-10
Abstract: PROBLEM TO BE SOLVED: To automatically detect occurrence of an abnormality by setting a waveguide in tight contact with a wall face, setting a matched load at a terminal end of the waveguide, and detecting a deformation of the wall face from a reflecting wave resulting from mismatching of an impedance of the waveguide. SOLUTION: A microwave pulse modulation signal generator 2 for transmitting pulse-modulated microwaves into a waveguide 1 is set at one end of the waveguide 1. A synchronous pulse is input to a microwave receiver 3 arranged at the side of the one end of the waveguide 1. A time of a reflection pulse resulting from an abnormality of the waveguide 1 is measured on the basis of the pulse. If the waveguide 1 is deformed, broken, etc., at a middle part, a propagation impedance of the waveguide 1 changes. In consequence, a transmission line is mismatched, whereby a pulse signal to be absorbed at a terminator 5 is reflected and returned to the microwave pulse modulation signal generator 2. The pulse signal is extracted through a directional coupler 4. A deformation and a point of the deformation of a tunnel can be detected in this manner.

IPC: G02B6/00
Filed: 1987-03-10
Abstract: PURPOSE:To enable to multiplex high speed information by converting the assigned wave length of the high speed information to the another different wave with the aid of a wave length conversion switch and exchanging the time slot of time division multiplex low speed information in a frame with the aid of a time switch. CONSTITUTION:The wave length lambda1 and lambda2, are assigned to the high speed information and the wave length lambda3 to the low speed information by an input light 10. The wave length lambdaa or lambdab is selected for the light signal of which wave length is multiplexed by a variable wave length filter 131-1 controlled by a primary wave length conversion control part 14-1 and converted to the desired wave length lambda1 or lambda2 again by a primary light control light modulator 132-1. The light signal of the wave length lambda3 of the time division multiplexed low speed information is sampled by a fixed wave length filter 15 and after that, the time slot in the frame is exchanged by a time switch 16-1 controlled by a primary time switch control part 17-1. Thus, as the time division multiplex is not executed for the high speed information, transmitting speed and the switching speed of a channel are not needed to be raised.

Abstract: PROBLEM TO BE SOLVED: To provide a three-dimensional optical memory device which is small and which can store large-capacity information. SOLUTION: A plurality of light diffusion elements 60 are arranged on the inner wall part 52 of a memory shell 50. LCD shutters 70 each of which is composed of a plurality of liquid crystal cells are arranged at the respective light diffusion elements 60. Incident light on the respective light diffusion elements 60 is divided into small luminous fluxes so as to be transmitted and cut off selectively according to recording information. The small luminous fluxes which are transmitted through the liquid crystal cells in the LCD shutters 70 are diffused into an optical storage medium 54. Interference fringes are formed in the optical storage medium 54 by the small luminous fluxes radiated from the plurality of light diffusion elements 60. Very small corner-cube prisms are spread on the inner face of the outer wall part 53 of the memory shell 50 so that reproducing light is returned surely to the original light diffusion elements 60. As compared with a case in which light incident on the light diffusion elements 60 is transmitted and cut off collectively, the amount of information which can be recorded is increased.
