Title: Ceramic sintered compact
Inventor: OTA MASAHIRO
IPC: C04B35/64
Filed: 1990-10-05
Abstract: PURPOSE:To effectively prevent cracks in edge parts from occurring by providing folded parts of L- or T-shaped cross section with a specific length in the ends of edge parts in a ceramic sintered compact having a prescribed value or above of edge width. CONSTITUTION:A ceramic sintered compact having a body part 1 and edge parts 2 with >= about 20mm width is produced. In the process, folded parts 3 of nearly L- or T-shaped cross section are integrally provided in the ends of the edge parts 2. The folded parts 3 are formed so as to afford the ratio [(L)/(T)] of the length (L) of the folded parts 3 to the thickness (T) of the edge parts 2 within the range of 0.1-10. Thereby, residual stress in the edge parts 2 can be relaxed to produce an integral product of the ceramic sintered compact of a complicated shape without producing cracks.

Abstract: The complete structure of human milk BAL cDNA is disclosed. The nucleotide sequences of the cDNA inserts of two clones overlap and together contain 2951 base pairs of BAL cDNA which codes for an open reading frame of 720 amino acid residues between initiation and termination codons. There is a putative signal sequence of 20 residues which is followed by a 61-amino-terminal sequence of BAL. The cDNA sequence also contains a 678-base 5'-untranslated sequence, a 96-base 3'-untranslated region, and a 14-base poly(A) tail. The deduced BAL protein structure contains in the carboxyl-terminal region fourteen repeating units of 11 amino acids each. The repeating units have the basic structure of Pro-Val-Pro-Pro-Thr-Gly-Asp-Ser-Gly-Ala-Pro-, with only minor substitutions. The cDNA is useful for expression of protein, study of structure, function and the effect of modification or deletion or addition of amino acids, including entire repeating units, and as probes for studies involving BAL or related lipases, including rat pancreatic lysophospholipase, cholinesterase, and acetylcholinesterase. <IMAGE>   <IMAGE>

Abstract: PROBLEM TO BE SOLVED: To receive earth pressure firmly by an integral arched structure, and to carry out the economical execution of works. SOLUTION: Piles 1 are driven so as to be placed on an arcuate curve indented towards the up-slope side at proper intervals. The down-slope side is excavated along the piles 1, buried forms 3 are stretched, concrete 4 is placed and a sheathing wall A is manufactured. A beam for connecting the upper ends of the piles 1 driven so as to be placed on the arcuate curve is constructed and a plurality of the piles 1 are unified as a sheathing structure for preventing a landslide. Since an arch effect is displayed by unifying the piles 1 and forming an arched structure, the structure capable of resisting large earth pressure is prepared. The piles 1 do not display separate function and resist earth pressure as the unified structure. Since the structure unified with the ground is formed by using the piles, the economical execution of works can be carried out.

Abstract: PURPOSE: To make an observer able to observe stereoscopic images with full presence near a display screen by arranging a display board provided with phosphors on one surface of a transparent plate and a separation means on the other surface inside a cathode-ray tube. CONSTITUTION: For the display board 3, many striped phosphors 32 extended in a vertical direction are formed on the back surface (the surface on the side of an electron gun 2) of a transparent glass plate 31 and many semicylindrical lenticular lenses 33 extended in the vertical direction are formed on the front surface (the surface on the side of a front surface glass part 1B) of the glass plate 31.

Title: Reactor core of fast breeder
Inventor: NAKAGAWA MASATOSHI
IPC: G21C3/33
Filed: 1990-10-09
Abstract: PURPOSE:To lessen a quantity of residual curvature of a fuel assembly and contrive the reduction of fuel drawing force by narrowing a gap wideness between the upper pads of the assembly of at least a neutron shielding body region which is larger than the gap wideness between the upper pads of the other assembly. CONSTITUTION:The gap wideness between the upper pads of each assembly 6 in a neutron shielding body region is set narrower than the region of the other assemblies (a core fuel assembly 1 and a radial blanket fuel assembly) and the other gap wideness between the upper pads. As the result, a bend limit in a reactor of a neutron shielding body 3 of the neutron shielding body region becomes large and a large bend by creep can be obtained. Since the bend is in the opposite direction of a swelling bend, a quantity of residual curvature can be reduced as the result. Thereby fuel exchange can be performed smoothly and the drawing force of fuel at the time of fuel exchange can be lessened.

Abstract: PURPOSE:To reduce irregularity in the exposure of an image plane during photography and to allow speed-light photography by providing a run speed varying means for a shutter leading member and a shutter trailing member to a camera equipped with a slit exposure type shutter. CONSTITUTION:The shutter leading blade 1 is fitted to tips of parallel arms 5 and 6 and supported rotatably on a base plate 9 through shafts 10 and 11. Further, the shutter trailing blade 2 is supported rotatably on the base plate 9. The leading blade 1 and trailing blade 2 are run crossing an aperture 9a to perform exposure. The shutter leading blade 1 is run first and a control circuit calculates its shutter speed to control the shutter speed of the trailing blade 2 on the basis of the calculated shutter speed. For example, when a slow shutter speed is required, the speed of the trailing shutter blade is made slower than a high-speed shutter speed. Thus, the means which vary the mean run speed of the shutter leading and trailing blades is provided to perform speed light photography over a wide shutter speed range, thereby eliminating irregularity in exposure.
