Title: Manufacture of graphite powder for lithium ion secondary battery negative electrode
Inventor: IWAHASHI TORU
IPC: H01M4/587
Filed: 1999-07-05
Abstract: PROBLEM TO BE SOLVED: To efficiently produce at a low cost and with less processes by crushing a raw needle coke, heating the resulting powder at a specific temperature in a fluidized state and then graphitizing it. SOLUTION: Since a raw needle coke contains a volatile portion of about 7-15 wt.%, the particle fusion associated with the removal of the volatile portion is inevitable when the raw needle coke is crushed and then is graphitized. Thus the raw needle coke is crashed and then a non-fusion heat treatment is conducted. The heat treatment is set at 200-700 deg.C and is conducted in a fluidized state to avoid the fusion during processing. For the gas to fluidize a powder, any of oxidizing gases such as air and non-oxidizing gases such as gaseous nitrogen can be used. When the heat treatment is conducted in an oxidizing atmospshere, the treating temperature is preferably set low as 200-500 deg.C. When the heat treatment is conducted in a non-oxidizing atmosphere, the treating temperature is preferably set 500-700 deg.C.

Abstract: PURPOSE:To prevent the breakdown or mishandling of a semiconductor device caused by the penetration of magnetic field or a rise in temperature by the provision of a magnetic sensor and a temperature sensor, by forming the resistors of transistors in a transistor(TR) differential amplifying circuit with superconducting materials whose resistance values are different from each other when their superconducting state is broken. CONSTITUTION:In an LSI chip 1 of an LSI internal circuit 2 having a TR differential amplification circuit 3, the load resistors of transistors TR Q1 and TR Q2 in the circuit 3 are formed with superconducting materials RS1 and RS2 whose resistance values are different from each other when the superconductivity state is broken down by a magnetic field and temperature, so that they function as a magnetic sensor and a temperature sensor. This construction prevents the breakdown of elements of the circuit 2 or the generation of mishandling of the circuit 2 accompanied by magnetic field penetration or temperature rise induced when a power source is shut down. The same performance is available even when the emitter resistors of TR Q1 and TR Q2 are formed with superconductivity materials.

Title: Electrifying conductive brush device
Inventor: YOSHIDA SADAAKI
IPC: G03G15/02
Filed: 1995-07-27
Abstract: PROBLEM TO BE SOLVED: To prevent deterioration of electrified characteristics of an image forming body by bringing a developing agent elimination member comprising porous material in surface contact with a conductive brush over its whole length of it for effectively eliminating toner attached to the conductive brush to come in contact with an image forming body. SOLUTION: An insulated toner elimination plate 50 comprising a porous ether-based urethane foam body is pressed to a conductive brush 1 2a, so toner attached to the conductive brush 12a is eliminated. The toner elimination plate 50 comprising the urethane foam body is of material of high heat resistance in which hydrolysis decomposition is hard to occur, so the toner elimination plate 50 can be pressed to the conductive brush 12a to bring in surface contact with it along the whole length of it without applying large load on the conductive brush 12a. Generation of friction heat by slide contact of the conductive brush 12a with the toner elimination plate 50 can thus be restricted to prevent plastic deformation of the conductive brush 12a.
