Title: Speed controller for electric vehicle
Inventor: AEBA HIDEAKI
IPC: B60L3/00
Filed: 1991-02-15
Abstract: PURPOSE:To reduce the number of facilities to be installed on the ground, to realize accurate speed control of electric vehicle and to enhance safety at the time of maintenance and inspection. CONSTITUTION:Photoelectric distance sensors 5A, 5B disposed in the advancing direction of an electric vehicle 2A traveling on a track 1 transmit optical signals 6A, 6B to reflectors 3A-3D disposed at the ends of linear traveling regions of electric vehicle. A current position detecting means counts the time to be elapsed after transmission of the optical signals before reception of reflected signals and the count is then converted into a current position of the electric vehicle thus determining the current position of the electric vehicle. A limit speed operating means operates a limit speed of the electric vehicle at current position based on the current position of the electric vehicle and prestored position limit speed data and a limit speed corresponding to the current position of the electric vehicle is fed to a speed controller 11.

Title: Impregnated type cathode
Inventor: YAMAMOTO YOSHIHIKO
IPC: H01J1/28
Filed: 1985-02-08
Abstract: PURPOSE:To stably maintain a monomolecular layer of low work function by forming a lower layer consisting of a high-melting-point metallic thin film and an upper layer consisting of a metallic thin layer containing Sc2O3 over the surface of a pellet prepared by impregnating a porous metallic base with an electron-emitting material. CONSTITUTION:First, a cathode pellet 1 is prepared by impregnating the holes 3 of a porous base 2 made of a material such as W with an electron-emitting material such as BaCO3. Next, a flattened layer 8 made of an element such as W or Os is fixed to the upper surface of the cathode pellet 1 by electron-ray heating. After that, a thin film 9 with a thickness of 10nm-1mum consisting of Sc2O3 and an element such as W is fixed to the upper surface of the layer 8 by vacuum sputtering or similar method, thereby making an impregnated cathode for a cathode-ray tube. Because of the above structure, even when a monomolecular layer composed of Ba, Sc and Os essential for maintaining the low work function of the cathode is broken due to some reason, the electron- emitting characteristic of the cathode is not deteriorated because Ba, Sc and Os are supplied during operation. Consequently, it is possible to achieve stabilized operation at low temperatures.
