Title: Manfacture of lower-boiling product from heavy oil
Inventor: HIROTA TAMOTSU
IPC: C10G47/22
Filed: 1991-03-15
Abstract: PURPOSE:To efficiently decompose a heavy oil with controlled usage of expensive hydrogen gas to give a lower-boiling product by heating a heavy oil in an atmosphere of a lower hydrocarbon gas or a gas mixture thereof at specified temperature and pressure. CONSTITUTION:A method for manufacturing a lower-boiling product by heating a heavy oil in an atmosphere of gas, wherein the heavy oil is heated at 800-1200 deg.C under a pressure of 3.5 bar or lower, preferably from near ordinary pressure to 3.5 bar, in an atmosphere of a lower hydrocarbon gas or its mixture with hydrogen gas. If the reaction temperature is below 800 deg.C, the heavy oil will not decompose sufficiently; if above 1200 deg.C, the heavy oil will rapidly decompose and carbonization will proceed so that the amount of an objective lower- boiling substance produced will decrease. If the pressure during the reaction is 3.5 bar or lower, no pressure-resistance device is necessary; therefore, this method is advantageous from the viewpoint of manufacturing cost. The heavy oil means an oil containing at least 90% aromatic polycyclic compound composed of at least three rings.

Title: Controller for unmanned travel enabling vehicle
Inventor: KONDO MASANORI
IPC: G05D1/02
Filed: 1992-05-21
Abstract: PURPOSE:To eliminate the trouble of moving a machine body backward, getting it out of a guiding line and disabling of automatic traveling by detecting that the machine body is set on an upward slope with a throttle aperture, and operating an emergency stop brake when the vehicle is stopped with the throttle aperture larger than a certain degree of the aperture. CONSTITUTION:An emergency solenoid 30 of a brake cylinder 37 is operated by a signal from a radio transmitter or the like. When the unmanned traveling vehicle is urgently stopped on a traveling path, which inclination is larger than 10 deg., to guide the vehicle with the guiding line, a controller part stops an engine and loads a parking brake with the brake cylinder 37 and while the parking brake is sufficiently loaded, however, the machine body is moved. Therefore, it is judged whether the throttle aperture is large or not and when this throttle aperture is large, it is judged that the vehicle is positioned on the upward slope. When the braking of the brake cylinder 37 is not completed, the emergency brake solenoid 30 is turned off, and emergency braking is actuated. Thus, the vehicle is prevented from moving backward.

Title: Method for coating adhesive diamond film on ultrahard tungsten carbide substrate
Inventor: MAIKERU JII PIITAASU
IPC: C01B32/949
Filed: 1992-04-22
Abstract: A cemented tungsten carbide substrate is prepared for coating with a layer of diamond film by subjecting the substrate surface to be coated to a process which first removes a small amount of the tungsten carbide at the surface of the substrate while leaving the cobalt binder substantially intact. Murakami's reagent is presently preferred. The substrate is then subjected to a process which removes any residue remaining on the surface as a result of the performance of the process which removes the tungsten carbide. A solution of sulfuric acid and hydrogen peroxide is presently preferred.A diamond coated cemented tungsten carbide tool is formed using an unpolished substrate, which may be prepared by etching as described above or by etching in nitric acid prior to diamond film deposition. Deposition of a substantially continuous diamond film may be accomplished by reactive vapor deposition, thermally assisted (hot filament) CVD, plasma-enhanced CVD, or other techniques.
