Abstract: PROBLEM TO BE SOLVED: To make it possible to anchor a slope protection block with a natural ground firmly by forming a hollow hole in a cross section rectangular shape in the longitudinal direction and increasing the thickness at the central part and reducing gradually the thickness of the block toward both side surfaces. SOLUTION: A precast reinforced concrete-made and rectangular-shaped rod-like slope protection block 1 is arranged to form a disk-shaped hollow hole 2 along the longitudinal direction inside based on a centrifugal molding method, thereby shaping up a cross section rectangle. An anchor insertion hole 4 is bored in the central part on the plane. The surrounding area around the insertion hole 4 is increased in thickness while the thickness to both sides is gradually reduced. Then, an anchor 5 is driven in the hole bored in the natural ground while the block 1 is placed so that the anchor may be centered. The anchor 5 is pulled so that it may be anchored with the slope A.  Then, since the anchor 5 is placed from a central position of the block 1, which is thick and rigid, bending deformation is produced, which makes it possible to prevent both ends from floating up and apply uniformly distributed load over the whole length of the block 1 and anchor the block with the surface of the slope firmly.

Title: Signal processing circuit of waveguide device
Inventor: IWASAKI YUTAKA
IPC: G01M11/02
Filed: 1992-09-11
Abstract: PURPOSE:To equalize the intensity of the light signal from a waveguide, in the signal processing circuit of a waveguide device, by providing a gain control means compensating the non-equality of the propagation loss at every waveguide. CONSTITUTION:The beam from a laser diode 1 is reflected by a half mirror 2 to be condensed to the surface of an object 5 by an object lens 4 through an XY two-dimensional scanning means 3. The reflected beam transmits through the mirror 2 to be condensed to a double mode waveguide 7. This beam is distributed to two waveguides 9, 10 and the distributed beams are respectively incident on photodetectors 11, 12 and electric signals having the intensity proportional to beam power is sent to amplifiers 13, 14. A differential amplifier circuit 15 detects the difference between both amplified outputs to output the signal corresponding to said difference. The output signals of the photodetectors 11, 12 are different in detection intensity because the propagation loss factors of the waveguides 9, 10 are different. The gain rates of the amplifiers 13, 14 are successively altered to be determined so that the output from the differential amplifier circuit 15 becomes zero. As mentioned above, by setting the gain rates and separately amplifying the same by the amplifiers 13, 14, the light powers emitted from a plurality of waveguides are equalized to be accrately detected.
