An alternator for use in an automobile includes a stator supported between a front housing and a rear housing, and a rotor connected to a rotor shaft and rotatably supported inside the stator. A cooling fan is positioned at an end of a pole core of the rotor. The cooling fan is coupled to the rotor shaft by engaging edges of a center opening of the cooling fan with a non-circular flange formed on the rotor shaft. The cooling fan is correctly positioned relative to the rotor shaft, without using a jig, both in the radial direction and in the rotational direction of cooling fan. Noises and vibrations due to rotational imbalance of the cooling fan are suppressed.

The LCD device includes a liquid crystal panel, a backlight unit, a circuit board disposed at rear side of the backlight unit, and a number of flexible substrates each mounting thereon a driver chip and connecting the terminals of the liquid crystal panel and the circuit board. The flexible substrate has a cut-out at each side edge thereof. A protrusion formed on the backlight unit or inner housing passes the cut-out to protrude toward the housing of the LCD device.

In a vehicular alternator, a stator is arranged to oppose a rotor in a housing. The stator includes a stator core, which forms a plurality of slots extending in an axial direction of the stator core, and a stator winding wound around the stator core. The stator winding includes electric conductors held in the slots. Each of the electric conductors has a circumferential width that is smaller than a circumferential distance between a first wall and a second wall defining the slot. The first wall and the second wall oppose each other in a circumferential direction. The electric conductors are alternately in contact with one of the first wall and the second wall.

A rotary electric machine includes a frame, a rectifying unit fixed to the frame, a rotor accommodated in the frame, a voltage regulator having a regulator section, an arm extending from the regulator section in a circumferential direction and a connector. The arm has a mounting potion at an end, and the connector is disposed between the mounting potion and the regulator portion.

An auxiliary plate (10) is fixed to a rear plane of a housing for fixedly holding a lamp unit (6) having a plurality of lamps. In the auxiliary plate (10), a convex portion and a concave portion are combined. The convex portion has a space between the housing and itself, which is formed by protruding a sheet metal, and the concave portion contacts with the housing by denting the sheet metal. In the auxiliary plate 10, an area for mounting a board vulnerable to heat is formed with the convex portion and an air layer performs as heat insulation. The convex and concave portions are arrayed in a direction where heated air easily flows in another area. Thus, rigidity can be remarkably increased compared to a flat-shaped sheet metal, and heat generated by a backlight is effectively dissipated, as well as a temperature rise and an occurrence of a temperature gradient are suppressed.

Disclosed is a process for producing an oxide catalyst for use in producing (meth)acrylonitrile from propane or isobutane by ammoxidation in the gaseous phase, the oxide catalyst comprising a compound oxide containing Mo, V and Sb as essential component elements, which process comprises subjecting a solution or slurry, in water and/or an alcohol, of a raw-material mixture comprising a Mo compound, a V compound and an Sb compound as essential raw materials to a specific oxidation treatment using an oxidizing gas and/or an oxidizing liquid before subjecting the solution or slurry to drying and subsequent calcination. Further, also disclosed is a process for producing a base-treated oxide catalyst by treating the above-mentioned oxide catalyst with an aqueous basic solution.

A process for producing ethylated benzene by a reaction of benzene with ethylene in the presence of a catalyst containing a zeolite .beta. by using a fixed-bed ascending-flow type reactor, which comprisesa) carrying out the reaction under conditions under which ethylene bubbles are present at the inlet of a catalyst layer when ethylene is fed upward from under the catalyst layer,b) recovering reaction products as a liquid from the upper part of the reactor and at the same time taking out a distillate composed mainly of unreacted benzene therefrom as vapor, andc) adjusting the temperature of the catalyst layer at its inlet to a temperature at least 50.degree. C. lower than the maximum attained temperature of the catalyst layer.
