Title: Method of removing iron contained in mineral oil derived from petroleum
Inventor: INOUE AKIRA
IPC: C10G67/02
Filed: 1986-05-07
Abstract: PURPOSE:To remove iron contained in an oil with high efficiency as with large treating capacity, by treating an iron-contg. mineral oil fraction derived from petroleum with a high gradient magnetic separator. CONSTITUTION:A mineral oil fraction derived from petroleum and containing 5ppm or more of iron is treated with a high gradient magnetic separator under the following conditions: an intensity of a magnetic field of 500-25,000 G; a temp. of room temp. to 400 deg.C; and a linear velocity of 0.1-50cm/sec. A mineral oil fraction derived from petroleum is fed into the space of a magnetic field of a high-gradient magnetic separator. This causes the iron contained in the oil to adhere to a ferromagnetic packing material, thereby removing iron. The high-gradient magnetic separator may be an electromagnet or permanent-magnet separator.

Title: Travel control device for mobile agricultural machinery
Inventor: OCHI RIICHI
IPC: F02B37/18
Filed: 1986-05-07
Abstract: PURPOSE:To obtain quick and stable load control by means of a motor, by detecting the sinkage of a work vehicle by means of a vehicle body sinkage sensor and, when the amount of the sinkage thus detected becomes large, automatically activating a supercharger of the motor. CONSTITUTION:When a traveling equipment 2 reaches a soft soil foundation, the equipment 2 sinks, and the amount of the sinkage of this work vehicle body 3 is detected by a vehicle body sinkage sensor 4. As soon as the amount of the sinkage detected by the vehicle body sinkage sensor 4 exceeds the present value, a supercharger 5 is activated in a linked motion with the sensor 4 so as to heighten the supercharging pressure of the fuel, thereby increasing the output of a motor 1. After the preset running speed is once obtained through an increase in the output of the motor 1, the sinkage of the travelling equipment 2 becomes less, thereby ensuring the smooth and stable work.

Abstract: PURPOSE:To prevent breakdown of wiring at a step part due to the steep shape of the end surface of a connecting hole even if a second Al wiring is formed, by gradually changing the flow rate ratio of a reacting gas by using a CVD method, forming an interlayer insulating film wherein an etching speed becomes quick from the lower part toward the upper part, and providing a connecting hole for connecting wirings in the interlayer insulating film by weak anisotropy etching. CONSTITUTION:A plasma nitride film as an interlayer insulating film 11 is grown to a thickness of about 1.0mum on a first Al wiring 10 by using a parallel planar type plasma CVD apparatus by a plasma CVD method. It is important that the interlayer insulating film 11 is adjusted in such a way that the lower the layer, the higher the Si content, and the higher the layer, the lower the Si content. When the Si content is varied, the etching speed increases toward the upper layer from the lower layer. Thereafter, resist 12 is applied in order to open a connecting hole for connecting wirings, and a mask is formed by aligning and exposure. Then, the connecting hole is opened by weak anisotropic etching 13. Then, the resit 12 is removed. Al is evaporated, and a second Al wiring 14 is formed.

Abstract: PURPOSE:To increase thermal efficiency, and to improve cooking ability, as well as not to spoil convenience for cleaning in a cooker, by providing a gas table which has a tubular or a reversely U-shaped passage around a top plate, and by making combustion exhaust gas coming out of exhaust opening provided on the edge of a top plate flow to the center part of a gas table. CONSTITUTION:Mixed gas of fuel and air passing through a mixing pipe 9, is burned on a burner 1 for red-heating. Combustion exhaust gas, passing through an exhaust gas passage 3 and an exhaust gas opening 5 provided on the edge of a top plate, is led to the center part of a gas table 7 through a gas passage provided in the gas table 7. The gas is supplied to the bottom of a cooking pan 8 in order to heat a material to be cooked in the pan. The gas table is heated by combustion exhaust gas while the gas is passing through the passages in the gas table 7, and the heat of gas is transferred to the bottom of a pan contacting the gas table by the heat transferring effect between them. While flames burning on the burner 1 for red-heating changes the burner surface into a radiating body, radiant heat permeating through the top plate made of permeating material heats the bottom of a cooking pan. Since a heating operation take place in all modes, heat transfer, convection, and radiation, extremely highly thermal efficiency can be obtained in a cooker.
