Title: Beneficiation of sulfide ore
Inventor: IZUMIKAWA CHIAKI
IPC: B03C1/00
Filed: 1982-09-18
Abstract: PURPOSE:To separate and collect bornite certainly in high yield, by inserting a magnetic separation process into the benecification process of a sulfide ore. CONSTITUTION:A complicated sulfide ore is subjected to Cu/Pb flotation to transfer Cu and Pb to a flotation side while Zn and pyrite to a precipitation side. The Cu/Pb floated ore is further subjected to Cu-Pb separation flotation and Cu is separated to a flotation side while Pb to a precipitation side to obtain a copper concentrate and a lead concentrate. The Zn/pyrite precipitation ore is subjected to Zn flotation to obtain a zinc concentrate. In this process, magnetic separation is inserted into either one of stages, that is, a stage A prior to Cu/Pb flotation, a stage B prior to Cu-Pb separation flotation and a stage C during obtaining the lead concentrate, especially, the stage C. In the magnetic separation process, when pulp containing bornite is supplied to a wet high magnetic force magnetic separator under magnetic field intensity of 10,000-20,000 Gauss, bornite is adhered to a matrix and, therefore, the matrix is taken out of a magnetic field after treatment to be washed by water and a bornite ore particle can be separated and recovered in high purity.

IPC: F16F9/08
Filed: 1983-09-07
Abstract: PURPOSE:To improve durability of a diaphragm through sufficient absorption of angular movement, transferred from the axle side, by means of a bearing, by a method wherein a mounting bracket is attached to a bearing placed to an outer shell. CONSTITUTION:A bearing 7 is attached to the outer side of a reduced part 2a of an outer shell 2, and a mounting bracket 8, which is adapted to be mounted to a member on the car body side or an axle member, is mounted to an outer race 7a of the bearing 7 directly or through the medium of a mount rubber. When a cylinder 1a is coupled to the axle side member of a vehicle, angular movement around the axis, transmitted to a cylinder 1a, is transmitted to the outer shell 2 through a diaphragm 5 and is absorbed by the bearing 7. This prevents high twist deformation of the diaphragm 5 occasioned by the angular movement of the cylinder 1a.

Filed: 1999-06-09
Abstract: PROBLEM TO BE SOLVED: To easily detect an address and the contents of data only by one execution of a program when an error occurs and to improve the efficiency of debugging. SOLUTION: A monitoring circuit 13 stores the same program as a program to be stored in a target memory 31 also in a temporary memory 12 by the same address. At the time of executing the program stored in the memory 31 by an MCU 11, the circuit 13 reads out the same data as the data read out from the memory 31 and a comparator 14 compares both the data with each other. When both the data coincide with each other by the comparison, the MCU 11 executes the read data, and when both the data do not coincide with each other, stores the address and both the data in the memory 12 and detects an error.

Title: Field effect type semiconductor device
Inventor: NAGATA KOUHEI
IPC: H01L29/80
Filed: 1978-12-26
Abstract: PURPOSE:To accomplish higher characteristics with an Al mono-crystal layer imposed between the semi-insulating compound semiconductor substrate and the mono- crystaline semiconductor working layer. CONSTITUTION:An Al mono-crystal thin film 20 is grown onto a GaAs semi- insulating substrate 21 by the molecular beam epitaxial growth method, and succesively, Sn adding n-type GaAs mono-crystaline epitaxial layer 22 is formed. Then, on the layer 22, are formed source Au.Ge and drain electrodes 23 and 24 and an Al gate electrode by an ordinary method. FET thus formed is connected in the wire as specified. This yields a depletion layer 30 on the operating layer 22 in proximity of the interface of the Al thin film due to contact of the semiconductor with metal while the voltage is not applied, allowing the width of the layer 30 to reach about 0.1mum when the layer 22 is 0.3mum at a carrier density of 1X10<17>cm<-3>. Therefore, there is no functioning as the operating layer in the proximity of the interface with the substrate 21 lower in the electronic movement within the layer 22. As FET works in the region with a constant electronic movement, a high output, high speed action provides excellent high frequency characteristics.
