Title: Fuel rod spacer
Inventor: MOROOKA SHINICHI
IPC: G21C3/344
Filed: 1987-11-06
Abstract: PURPOSE:To improve heatproof performance and to improve the critical output by forming projections which divert the flow directions of the cooling liquid films moving axially along the inside walls of cylindrical cells toward the outside surfaces of fuel rods on the inside walls of the respective cylindrical cells in the circumferential direction thereof. CONSTITUTION:The respective cylindrical cells 8a are formed with fixing stoppers 10 at two points by recessing the upper edges of the bodies toward the inside. The projections 17 are formed circumferentially on the inside walls of the cylindrical cells 8a. The positions where the projections 17 are formed are preferably the upper half regions on the secondary side of the cylindrical cells with respect to the flow of the coolant flowing in the cylindrical cells. The liquid films of the two-phase flows flowing axially along the inside walls of the cylindrical cells 8a are turned in the flow direction toward the outside surfaces of the fuel rods 4 by collision against the projections 17. The coolant is, therefore, capable of effectively lowering the outside surface temp. of the fuel rods 4 by sufficient contact with the fuel rods 4. The critical output of the fuel assembly is thus improved, since the coolant is capable of effectively lowering the outside surface temp. of the fuel rods 4 and of preventing boiling transition.

Title: Image forming method
Inventor: SAIDA SHINSUKE
IPC: G03F7/26
Filed: 1986-11-21
Abstract: PURPOSE:To permit formation of a visible image on transfer paper as well by exposing the picture image to microcapsule (MC) paper and forming a latent image by the cured and uncured state of the microcapsules, then superposing the transfer paper thereon and transferring the picture image thereto by pressurization. CONSTITUTION:The microcapsules 3 in regions P1-P3 corresponding to the picture image 11 are cured when an original 10 formed thereon with the picture image 11 is exposed to the paper 12 for MC. The transfer paper 13 is superposed on the paper 12 for MC on which the latent image is formed by the cured and uncured state. When said paper is pressurized, the microcapsules existing in the ergions P1-P3 are destructed by the pressurization and the photopolymerizable monomer at the inside central body bleeds to the outside. The dye precursor material contained therein, therefore, forms a color by reacting with a reactive group layer consisting of an acidic resin. The color forming material is thereby transferred onto the transfer paper 13. The final copying of the picture image to plain paper is permitted.

Title: Preparation of vitamin k2 medicine for oral administration
Inventor: NAKAJIMA KAZUKO
IPC: A61K31/12
Filed: 1984-12-24
Abstract: PURPOSE:To produce an easily absorbable vitamin K2 agent for oral administration, by dissolving vitamin K2 in a specific triglyceride or its mixture. CONSTITUTION:The objective agent can be produced by dissolving vitamin K2 in a mixture of one or more triglycerides wherein the carbon number of each constituent fatty acid group is 16-18 (e.g. triolein). Vitamin K2 is effective to activate the hemostatic mechanism i the body and is used for the remedy of hemorrhage and hypoprothrombinemia, however, it has poor absorbability by oral administration and accordingly it is administered usually by intravenous injection or intramuscular injection. The drug preparation dissolved in the above triglyceride gives high drug concentration in blood by oral administration, and is rated as a peroral drug having excellent absorbability. Since the triglyceride has low toxicity, the vitamin K2 peroral drug of the present invention has also low toxicity and can be used safely for the prevention and remedy of hemorrhage and hypoprothrombinemia.

Title: Wafer-thin cutting blade
Inventor: ANDO MANABU
IPC: B24D5/12
Filed: 1987-11-05
Abstract: PURPOSE:To make one-sided wear in a wafer-thin cutting blade hard to occur as well as to reduce a bend of the blade edge by setting a plate material low in grain content percentage to a first layer, and laminating each second layer or a plate material, high in the grain content percentage as compared with the first layer, at both sides of this first layer. CONSTITUTION:When a material is cut with a three-layer structural cutting blade 4 of less than 0.5mm in thickness, the side of second layers 2, 3 high in grain content percentage at both sides in harder to wear than a first layer 1 low in this grain content percentage, so that a tip of the blade 4 is gradually worn out into a form with each crest on two outer layers 2, 3. In addition, since there are provided with the first layer 1 easy to wear and the layers 2, 3 hard to wear in this cutting blade 4, these layers 1-3 are worn out as being regulated with one another, and thus one-sided wear is also little. With suchlike wear cause, a cutting surface of the material comes hard to be bent, and cutting rectilinearity in the cutting direction is improved and, what is more, any possible scratches, chipping and so on are hard to occur on the cutting surface.

Title: Surface shape measuring apparatus
Inventor: KANEKO REIZO
IPC: G01B11/24
Filed: 1988-11-08
Abstract: PURPOSE:To enable easier measurement and a reduction in erroneous measurement by combining an optical microscope with a probe type surface shape measuring device capable of measuring a ruggedness of a measuring surface at a high accuracy. CONSTITUTION:A tip radius of a probe 1 is formed at submicron order and fixed at the tip of a plate spring 2, which 2 is supported with a probe spring supporter 4. As the plate spring 2 is small and close to a measuring surface 3, it can be observed as sharp image together with the measuring surface 3 thereby facilitating the setting of the probe 1 at a desired position on the measuring surface 3. Then, the device 4 is driven with a drive controller to press the probe 1 onto the measuring surface 3 by a specified force. Then, a changeover mirror 8 is driven to switch an optical path and when the measuring surface 3 is moved at the right angle to the optical axis with a displacement sensor 9 in action, a plate spring 2 is displaced along a ruggedness of the measuring surface 3. As a result, a surface shape is obtained from a detection value of the sensor 9 and a movement of the measuring surface 3.

Title: Texture treatment of amorphous carbon substrate for magnetic disk
Inventor: OOTA YUKIHIRO
IPC: G11B5/84
Filed: 1991-09-30
Abstract: PURPOSE:To form a good texture surface by polishing the surface of an amorphous carbon substrate to roughness of a prescribed range and to the ratio of the surface roughness in a circumferential direction and radial direction to a prescribed range, respectively, then subjecting the surface to a prescribed anodic oxidation treatment. CONSTITUTION:The surface of the amorphous carbon substrate is polished, by which the surface roughness 12a thereof is specified to 5 to 40Angstrom  and the ratio Ra1/Ra2 between the surface roughness Ra1 in the circumferential direction thereof and the surface roughness Ra2 in the radial direction thereof is specified within a 0.85 to 1.15 range. The amorphous carbon substrate having the polished surface is then subjected to the anodic oxidation treatment, by which the texture is formed thereon. The surface of the amorphous carbon is roughened in this way. The attraction of a magnetic head to a magnetic disk is, therefore, prevented and the floating height of the magnetic head is decreased. Since the formation of the texture is executed by the anodic oxidation treatment, the surface roughness is uniformized and the generation of scratches is suppressed. The generation of pits is thus prevented.
