  • Publication number: 20190078566
    Abstract: A screw pump has a male screw accommodation hole and a female screw accommodation hole formed in a pump housing. A male screw member and a female screw member are respectively accommodated in the male screw accommodation hole and the female screw accommodation hole. A male-side clearance is formed in a radial direction between the male screw member and the male screw accommodation hole and a female-side clearance is formed in the radial direction between the female screw member and the female screw accommodation hole. The female-side clearance is made to be larger than the male-side clearance, so that the female screw member can easily move in a direction away from the male screw member to the female-side clearance when any extraneous material is going to be wedged between the male screw member and the female screw member, to thereby prevent a locked condition of the screw members.

  • Patent number: 10050224
    Abstract: The purpose of the present invention is to provide the following: an optical-device surface-sealing composition that makes it possible to fabricate an optical-device-using display with a low amount of warpage even if there is a large difference between the coefficients of linear expansion of substrates used in said display; a display with a low amount of warpage; and a manufacturing method therefor. The storage modulus of elasticity (G?(80)) of this optical-device surface-sealing composition, measured at 80° C. after said composition is heated from 40° C. to 80° C. at 5° C./min and then held at 80° C. for 30 minutes, is between 1.0×103 and 2.0×106 Pa.

  • Patent number: 8933043
    Abstract: The present invention relates to novel methods for modulating the activity of p53 tumor suppressor protein by affecting p53 translational regulation. More specifically, the invention relates to novel methods for modulating p53 mRNA translation in a cell by affecting a function of a p53 5?-untranslated region (5?UTR), including its interaction with proteins such as Ribosomal Protein L26 (RPL26), nucleolin, and p53. The invention also relates to the use of these methods for treating cancer, neurodegenerative disorders and minimizing the negative effects of cellular stresses.
