An automatic assembling method and apparatus for a differential gear, for simplifying the structure of the apparatus and achieving positive assembling without damage to gear teeth of gears, wherein while positioning a pair of side gears R, R at predetermined positions in a differential case C, a pinion gear P and a spherical washer Q are fitted to coincide with each other at shaft insertion bores thereof so as to be inserted with an internal chuck 14 from inside of the pinion gear P (i.e., center side of the differential case), thereby the pinion gear P and the spherical washer Q are held together at respective internal surfaces. Thereafter, the pinion gear P is meshed with the side gear R at gear teeth portions thereof at an opening H of the differential case C, and the pinion gear P is moved to an assembling position while holding the side gear rotatable. A shaft S is then inserted from a shaft hole e of the differential case C, thereby assembling the differential gear.

Amino-acid amide derivatives, method for producing the same, and

Amino-acid amide derivatives, processes for preparing the same,

The present invention provides an agricultural or horticultural fungicide including an effective amount of an amino-acid derivative represented by the formula: ##STR1## wherein R.sup.1 represents a lower alkyl group (optionally having at least one same or different substituent of a halogen atom, an alkoxy group, and a cyano group), R.sup.2 represents an ethyl group, or an n-propyl group, R.sup.3 represents a hydrogen atom or a lower alkyl group, R.sup.4 represents a hydrogen atom, R.sup.5, R.sup.6, and R.sup.7 independently represent a hydrogen atom or a lower alkyl group, R.sup.8 represents a hydrogen atom, or a lower alkyl group, Z.sup.1 and Z.sup.2 independently represent an oxygen atom or a sulfur atom, Z.sup.3 represents an oxygen atom, or a sulfur atom, Q represents a phenyl group, m represents an integer from 0 to 2, and n represents 0 or 1. The amino-acid amide derivatives according to the present invention exhibit superior control of cucumber downy mildew (Pseudoperonospora cubensis), tomato late blight (Phytophthora infestans), and grape downy mildew (Plasmopara viticola), and are effective for potato late blight (Phytophthora infestans). In addition, the agricultural or horticultural fungicides of the present invention are also characterized in that they are not harmful chemicals and exhibit excellent characteristics such as systemic action, residual activity, and persistence after rain-fall.

The present invention provides a condensed heterocyclic derivative represented by a formula: ##STR1## wherein R.sup.1 represents a lower alkyl group, an alkenyl group, or the like, R.sup.2, R.sup.3, R.sup.4, R.sup.5, and R.sup.6 independently represent a hydrogen atom, a lower alkyl, or the like, W is represented by --OC(O)--, --SC(O)--, or the like, and Z represents a 2-indolyl group or the like. The present invention also provides an agricultural or horticultural fungicide which comprises an amount of the condensed derivative known to be effective as a fungicide. The agricultural or horticultural fungicide according to the present invention exhibits a superior control effect for downy mildew and late blight, without harm to nonfungal, photosynthesizing plants.
