Title: Production of carbon material
Inventor: NOJIRI TAKESHI
IPC: C01B31/02
Filed: 1991-07-24
Abstract: PURPOSE:To surely obtain the high-density carbon material having a uniformly fine structure by packing a powder mixture composed of carbonaceous aggregate and binder into a forming mold, deaerating the inside of the mold, heating and pressurizing the powder mixture under a reduced pressure and calcining the molding. CONSTITUTION:The carbonaceous aggregate (e.g.: pitch coke powder) and the binder (e.g.: coal tar pitch) are kneaded or mixed and the mixture is ground at need, by which carbonaceous raw material powder 5 is produced. This carbonaceous raw material powder 5 is then packed into the forming mold for hot pressing and the inside of the forming mold is deaerated via a deaeration pipe 6. The mold is simultaneously heated by a heater 2 and the carbonaceous raw material powder 5 is molded by heating and pressurizing under the reduced pressure. The resultant molding is taken out of the forming mold, is calcined in accordance with the conventional method and is further graphitized at need to afford the carbon material. Open cells are formed on the surface layer of the molding in this way and, therefore, the gases generated in the mold are effectively dissipated to the outside.

Filed: 1995-07-20
Abstract: PROBLEM TO BE SOLVED: To simulate a wide mass difference range by inserting a time circuit with a variable time constant into a control circuit and controlling the time constant to be proportional to a difference in inertia mass to be simulated. SOLUTION: A differential circuit 11 and a subtraction circuit 13 are provided in a control circuit 9 to allow a time constant T in a time circuit 10 to be changed in synchronization with a difference Δθ in mass inertia moment between a running vehicle 5 and a test table. In a control process, the circuit 11 continuously computers variable torque target values which are changed with the difference Δθ. The circuit 13 computes the difference Δθand controls the circuit 11. The circuit 10 contains a PT1 element and has a time constant T, T=c.Δθ (c: constant). The constant (c) is a positive value and so the difference Δθis required to be positive or zero. For accurate mass simulation, the amplitude coefficient of the PT1 element is required to be 1.  In this way, dynamic control is stabilized and a wide mass difference range is also controlled.
