A method for producing simple planetary gear devices is provided in which minimum backlash is satisfactorily realized and maintained with a fewer number of parts without creating any space-related inconveniences. A dummy carrier pin is used which is provided with a rotation support section whose axis can be moved in the radial direction and can support a planetary gear around the rotation support section such that the planetary gear can rotate. The planetary gear is assembled, then, a sun gear is selected and assembled, and the positions of the dummy carrier pin are fixed. Thereafter, the dummy carrier pin is removed, and a carrier pin to be used in actual power transmission is press-fitted into the carrier at the position determined by the dummy carrier pin.

Provided is a wheel driving device which drives a wheel by output rotation of a reduction device disposed on an inside in a radial direction of the wheel. The reduction device includes an output member connected to the wheel, and a pair of bearings supporting the output member. In the pair of bearings, the bearing on a side opposite to a vehicle body has a smaller outer diameter than that of the bearing on a vehicle body side. An injection passage member of a medium injected into the wheel may be disposed on an outside in a diameter direction of the bearing on the side opposite to the vehicle body.

This invention provides a composite material useful for size reduction of electronic components and circuit boards mounted on electronic equipment and exhibiting a low magnetic loss (tan δ), and a manufacturing method thereof. The composite material contains an insulating material and particulates dispersed in this insulating material, the particulates being previously coated with an insulating material having substantially the same composition as that of the coating insulating material. The particulates consist of an organic or inorganic substance and preferably have a flat shape. The insulating material may be an insulating material commonly used in the field of electronic components. The composite material of the invention is preferably manufactured by a manufacturing method in which the particulates are previously coated with an insulating material and dispersed in an insulating material having substantially the same composition as that of the coating insulating material. The composite material of the invention can be applied as a material for circuit boards and/or electronic components to realize further reduction in size and power consumption of information and telecommunication equipment in a frequency band of several hundred MHz to 1 GHz.

A displaying apparatus comprises a CRT capable of displaying picture elements of n rows by m columns and a VRAM (Video RAM). The VRAM comprises a CRT area having addresses of n rows by m columns identical to those of the CRT and a first and a second menu areas formed at both right and left sides of this CRT area. Display data of a formatted document is stored in the CRT area, being converted into a video signal to display an image of the formatted document by means of the CRT. To point a blank space of the formatted document, as cursor is further displayed on the CRT. When a menu display is required, the data of the required menu is stored in the first and the second menu areas, being converted into a video signal. A CPU decides the leading address of the VRAM to start the display so that the cursor and the menu are displayed simultaneously on the CRT screen. Thus, an erasure of the cursor from the CRT screen can be prevented even when the menu is displayed.
