Abstract: An electric generator for a railroad train is provided with a stationary axle mounted to a base frame of a railroad car of the railroad train; a wheel mounted on either end of the stationary axle for rotation relative to both the stationary axle and a rail; an iron yoke secured to an outer surface of the wheel; a plurality of spaced, permanent magnets secured to an inner surface of the iron yoke; and a stator secured to either end of the stationary axle and including an armature winding thereon, the armature winding being spaced from the permanent magnets. In response to rotation of the wheel, electric current is produced by the armature winding due to a relative movement of the armature winding and a magnetic field generated by the permanent magnets.

Abstract: A high-sheet-resistance polysilicon resistor for integrated circuits is achieved by using a two-layer polysilicon process. After forming FET gate electrodes and capacitor bottom electrodes from a polycide layer, a thin interpolysilicon oxide (IPO) layer is deposited to form the capacitor interelectrode dielectric. A doped polysilicon layer and an undoped polysilicon layer are deposited and patterned to form the resistor. The doped polysilicon layer is in-situ doped to minimize the temperature and voltage coefficients of resistivity. Since the undoped polysilicon layer has a very high resistance (infinite), the resistance is predominantly determined by the doped polysilicon layer.

Abstract: A novel rearview directional control device for a rearview mirror, either a conventional rearview mirror or a self-cleaning rearview mirror, is provided. The present rearview directional control device for a conventional rearview mirror includes a mirror body mounting therein a spherical plain bearing having an inner ring securing therein a sleeve coaxially fixing thereto a mirror disk having a mirror, an eccentrical wheel engaging with the sleeve and having a rotating axis non-parallel to the shaft axis in a manner that when rotated, the shaft axis will be inclined.

Abstract: A rearview mirror includes a mirror body pivotally connecting thereto a securing frame mounting therein a rotatable carrier mounting therein a transparent glass capable of being set in rotation by an energized motor. When the securing frame is held against a door window of a vehicle, the transparent glass will be rotated and enable the driver to clearly see the rearview mirror through the door window and the transparent glass in a rainy or snowy day. The height of the securing frame can optionally be adjusted so that the driver can choose the best angle to see the rearview mirror through the door window and the transparent glass mounted in the securing frame.

Abstract: In a magnet-floating toy running inside a loop of vacuum-like state, a .perp. shape monorail is provided within a loop of air-tight, transparent round pipes, air within the loop is drawn by suction to make loop reach a vacuum-like state to reduce air resistance. In the two extended wings of the monorail and also underneath the surfaces of the car body, permanent magnets are installed and are arranged so that the magnet poles of the two magnets are the same to induce repulsion force and that when the car rides on the monorail, it may float. Power is supplied from source outside the loop to the conductive rail mounted in the top surface of the monorail and through the brush, then in turn, transmit to the motor. Thus motor will enable car to run within the loop.

Abstract: An object of the present invention is to provide a self-cleaning rearview mirror, attached to the outside of many different kinds of vehicles. An advantage of the invention is that it provides a clear rearview for the drivers.

Abstract: A process for manufacturing regenerated leather characterized by preparing a short-fiber and a long-fiber leather pulps from wasted natural leather; sending the two kinds of pulps separately to a refrigerator for freezing and then drying in a vacuum dryer; thus forming two sheets of cake-like leather by combining the two sheets to one and dipping with proper bonding agent, the long-fiber leather sheet is fluffed by a fluff-forming machine thus to form a regenerated natural leather.
