Title: Skeleton construction of underwater structure
Inventor: WATANABE KENICHI
IPC: E02D29/045
Filed: 1993-04-27
Abstract: PURPOSE:To make wall thickness be thinned as well as to reduce the cost of production by partitioning the inner part of an outer wall into four spaces extending in the vertical direction, with a vertical wall, while forming this outer wall into a convex curved surface projecting to the outside. CONSTITUTION:A skeleton 2 of an underground parking space or the like is provided with a skeleton body 3 as the outer wall, and the inner part is partitioned into four spaces 5 extending in the vertical direction, with a section cruciform vertical wall 4 consisting of a horizontal wall 4a and a vertical wall 4b. Next, a skeleton body constituent wall 11 surrounding these spaces 5 is formed into a convex curved surface protuberant to the outside. In succession, this convex curved surface is made to be a plane aggregate consisting of plural rectilinear continuous lines whose external line is bent at the specified angle, while a center O of this curved surface is situated almost midway in each space 5. In addition, this convex curved surface is altered to a circular curved surface at need. With this constitution, even if wall thickness is thinned to some extent, strength is securable, so the material cost is reducible, and since a wasteful space is more decreased than a cylindrical sectional skeleton, a digging quantity is reducible and, what is more, buoyancy by means of water pressure is reducible as well.

Title: Adaptor for ac power source
Inventor: MIURA TAKEHIRO
IPC: H02J7/34
Filed: 1997-04-02
Abstract: PROBLEM TO BE SOLVED: To enable power supply to a load, even if the power feeding function of an AC power source adaptor stops by service interruption etc., by adding a backup power advice to an adaptor body. SOLUTION: A battery terminal 11 is formed on one side of a cam-operated coder 10. When an AC power source adaptor is used for a cam-operated coder in the curse of collecting data, the plug 14 of a power cable 13 is inserted into a plug socket for AC power sources, and an adaptor 12 is fitted to the battery terminal 11 of the cam-operated coder 10. Then a DC output outputted from the converter circuit of the adaptor 12 is supplied to a load when a secondary battery 16 is fitted to secondary battery connecting terminals 15, charging is performed to an extent capable of compensating the self discharge of the secondary battery 16 supplying power to the load. Power is supplied from the secondary battery 16, since the power supplying function of the adaptor 10 lowers, when the plug 14 of the power cable 13 comes off from an AC plug socket in the cource of collecting data, or when power fails. Consequently, it becomes possible to prevent the interruption of the load.

Title: Differential transformer
Inventor: IYODA HIROTADA
IPC: G01D5/22
Filed: 1984-05-17
Abstract: PURPOSE:To use the differential transformer for a long time with high reliability, by attaching iron core guides to both end parts of a protecting tube so that a movable iron core part is not contacted with a bobbin and the protecting tube even though the transformer is used for a long time. CONSTITUTION:Both end parts of an outer wall 21 of a protecting tube 20 are extended from end walls 22 by a specified length. A recess 23 is formed between the extended pat 21A and the end wall 22 having a end wall hole 22A on each side. Disk shaped thick iron core guides 30 are coupled in the recesses 23. The diameter of a guide hole 31 at the center is smaller than the diameters of the central part of the end wall holes 22A or the hollow part of a bobbin 2. a movable iron core part 4 penetrates the guides 30. The core part 4 is provided in the bobbin 2 in the protecting tube 20 so that the part 4 is not contacted with the bobbin. The deviation of the iron core part 4 is restricted by the guide holes 31 having the small diameter in the guides 30, which are provided at both end parts of the protecting tube 20. Even if centering is erroneously performed, no frictional sliding occurs between the bobbin 2 and the protecting tube 20 at all. Therefore, the transformer can be used safely for a long time.

Title: Ocular for visual display device
Inventor: KENNO KOKICHI
IPC: G02B27/02
Filed: 1993-04-27
Abstract: PURPOSE:To provide the head mount type display device through which an image can be observed sharply up to its periphery at a wide display field angle by compensating the chromatic aberration by using two glass kinds. CONSTITUTION:The ocular 2 consists of a negative meniscus lens which is convex to the side of an entrance pupil position 1 and a biconvex lens, which are adhered together. It is important that this constitution satisfies 14<lambdad1-lambdad2, where lambdad1 is the Abbe number of a glass material which is large in Abbe's number and lambdad2 is the Abbe's number of a glass material which is small in Abbe number. When the difference in Abbe's number decreases 14 beyond the lower limit of the conditional inequality, the chromatic aberration quantity is undercompensated and the generation of the chromatic aberration of power can not be compensated, so that the resolving power at a peripheral field angle decreases. Further, it is important to satisfy 1<¦R/F¦<3, where R is the radius of curvature of the image plane of the ocular system by backward tracking and F is the focal length of the ocular system.

IPC: C12P7/44
Filed: 1979-08-09
Abstract: PURPOSE: To obtain a high-purity long-chain dicarboxylic acid, by dissolving a long chain dicarboxylic acid separated from a fermentation broth in an aqueous alkali, adding activated clay to the aqueous solution, filtering the broth under pressure, and acidifying the filtrate to separate the long-chain dicarboxylic acid.  
     CONSTITUTION: A microorganism capable of producing a dicarboxylic acid is incubated in a culture medium of a 10W18C straight chain hydrocarbon, e.g. n tridecane, as a substrate to give a fermentation broth, which is filtered through diatomaceous earth under pressure. The filtrate and the cake washing are mixed to separate and deposit the formed long-chain dicarboxylic acid. The separated and deposited dicarboxylic acid is dissolved in an aqueous solution of NaOH etc., and adjusted to pH about 11. Activated clay or acid clay is added to the solution, and the solution is filtered under pressure with agitation. The filtrate is then adjusted to pH≤4 to deposit the objective dicarboxylic acid of purity ≥97% with slight coloration. The dicarboxylic acid is further dissolved in an alkaline aqueous solution, and  the same operations are repeated to give a white product of higher purity (99%).

Abstract: PROBLEM TO BE SOLVED: To ensure a sufficiently long impact absorptions stroke by a method wherein a center beam whose front end is coupled approximately to the central part of a front end cross member and a rear end is coupled to a position situated above the rear end, and a coupling member intercoupling a center beam and a side beam. SOLUTION: An impact absorption part 50 comprises a pair of right and left side beams 51 extending obliquely upward frontward from the two end parts of a cross member 41a; and a center beam 52 paralleling the intermediate thereof and extending obliquely upward rearward. The tip parts of the side beam 51 and the center beam 52 are attached to a bumper 53, and the rear end parts of a center beam 52 is supported by a coupling member 54 curved from right and left side beams 51 and vertically extending. Since an impact absorption part 50 is formed in a triangular shape as seen from a side, the side beam 51 and the center beam 52 are not vertically bent during absorption of an impact but deformable. As a result, a sufficiently long impact absorption stroke is ensured.
