Abstract: A recording paper cassette includes a recording paper cassette body in which the leading side of recording paper in its transfer direction is fixed at the lower part of the recording device body in a roughly horizontal state, a cassette cover detachably attached to the recording paper cassette body, a first guide secured at the recording paper cassette body, which is able to position the end parts of the rear edge of placed recording paper in its transfer direction; and a second guide which is able to position the end part of recording paper in its width direction. The first guide is turnably provided on the bottom of the recording paper cassette body, and the second guide is slidably provided on the bottom of the recording paper cassette body.

Abstract: The object of this invention is to provide a therapeutic medicine for cystic fibrosis. The therapeutic medicine for cystic fibrosis according to this invention contains an alginate lyase capable of lysing the alginate produced by strains of microorganisms of the genus Pseudomonas as the active ingredient.

Abstract: A cell culture method proliferates microorganisms, particularly fungi such as molds, actinomycetes, animal cells, plant cells and so on to produce useful substances such as antibiotics, enzymes, proteins, polysaccharides, physiological active substances, and animal and plant hormones. Porous material including medium and cells to be proliferated is moved, whereby air is supplied to the surface of the porous material.

Abstract: A monoclonal antibody which specifically binds okadaic acids and a process for producing the monoclonal antibody by culturing a cell strain capable of producing the antibody. The monoclonal antibody to okadaic acids labelled with an enzyme is useful for assaying okadaic acids.

Abstract: A power transmitting V-belt comprising an endless metal band held by stopper members on a multiplicity of V-shaped metal blocks which are linked to one another, wherein a pair of free ends of each stopper member are retained in a pair of retaining grooves on the associated metal block, which pair of retaining grooves include a tapered guide section adapted to guide the free ends of the stopper member from its free state to its stressed state retained in the retaining grooves at the time of mounting the stopper member to the metal block. This simplifies the assembling procedure.

Abstract: There are disclosed a herbicidal composition containing, as an active ingredient, a phenoxyalkylamide derivative represented by the formula ##STR1## wherein X, n, Y, Z, R.sup.1, R.sup.2 and R.sup.3 have the same meanings as defined in the specification, and a method for controlling weeds by the use of the same. The herbicidal composition according to this invention shows a superior weed-killing activity by pre- and post-emergence treatment in soil.

Abstract: A power transmission V belt for being trained around driver and driven pulleys for transmitting power therebetween includes a loop-shaped metallic belt and a plurality of metallic V blocks mounted on the metallic belt successively in the longitudinal direction thereof. A a self-lubricating, heat-resistant, wear-resistant hard layer is coated on at least one of a radially inward surface and opposite side surfaces of the metallic belt, and radially outward surface and opposite side surfaces of the V blocks. The loop-shaped metallic belt comprises a stack of metallic members, and the self-lubricating, heat-resistant, wear-resistant hard layer is coated on at least one of confronting surfaces of superimposed ones of the metallic members.

Abstract: A V-belt transmission apparatus made of a pair of endless metallic belts and a plurality of V-shaped metallic members disposed in series in a stacked condition on the belts. Each V-shaped metallic member has laterally open, channel shaped grooves on both sides with the metallic belt on each side being inserted in the groove on that side. Each V-shaped metallic member includes a main body having a projection portion and a stopper member prepared separately from and attached to the projection portion of the main body. The stopper member forms upper wall portions defining the channel shaped grooves together with the main body.

Abstract: There are presented new diphenyl ether derivatives having a substituent selected from a halogen atom, a trifluoromethyl group and a methoxy group at the 4-position in one phenyl moiety, having optionally also halo-substituents at the 2- and 6-positions, and having a nitro group at the 4'-position and a substituent selected from an unsubstituted or substituted (1,3-dioxorane-4-yl)methoxy group, an unsubstituted or substituted (1,3-dioxa-5-cyclohexyloxy) group and an alkyl- or (substituted)amino-sulfonyloxy group at the 3'-position in the other phenyl moiety. They exhibit improved herbicidal effects on various weeds without any adverse phytotoxic effect on crops, e.g. rice seedlings.

Abstract: New diphenyl ether derivatives having one to three substituents selected from a halogen atom and a trifluoromethyl group at any optional one to three positions of the 2'-, 3'-, 4'-, 5'- and 6'-positions in one phenyl moiety and nitro group at the 4-position and unsubstituted or substituted aminosulfonyl group at the 3-position in another phenyl moiety. They have a superior herbicidal effect and can be prepared starting from a known 3-benzylmercapto compound through three steps.
