Title: Magnetic recording system
Inventor: ADACHI OSAMU
IPC: G11B5/02
Filed: 1984-04-18
Abstract: PURPOSE:To eliminate the magnetic interference between an erasion core and a read/write core in a signal recording mode and to decrease the reading errors in a reproducing mode, by applying a magnetic flux having the opposite direction to and the same quantity as the magnetic flux which leaks out to the read/write core from the erasion core. CONSTITUTION:In a signal recording mode a switching transistor 28 is turned on to make an erasion coil 13 conduct. Then an erasing DC magnetic flux is energized to an erasion core 10. At the same time, a read/write coil 11 also conducts by the transistor 28. Then a DC magnetic flux is energized to a read/write core 5. In this case, the magnetic flux energized by the coil 11 makes a round of loop of a read/write L type core 2   read/write gap 1   a read/write I type core 3   a read/write back bar core 4   the core 2. This magnetic flux is set opposite to the direction of the magnetic flux leaked out of the core 10 at the gap 1. Therefore a resistance 32 is controlled to a proper level of resistance. Thus it is possible to eliminate the effect of the magnetic flux leaked out of the core 10 in a recording magnetic field.

Title: State estimating device
Inventor: NISHIMURA KAZUO
IPC: H02J3/00
Filed: 1987-03-31
Abstract: PURPOSE:To estimate a state in a short time by binomially expanding a slope vector function concerning the state variation of an evaluation function with respect to a state variable vector estimated initial value and a vector of variation from this value. CONSTITUTION:A first arithmetic means 5-1 takes in various measured values and object system constants to obtain an observable value to be given as the function of a state variable corresponding to measured values, and the slope vector concerning the state variable of the evaluation function defined by the weighted square sum of differences between this observable value and measured values is binomially expanded with respect to the state variable vector initial estimated value and the vector of variation from this value. A second arithmetic means 5-2 uses the expansion formula concerning the variation vector obtained by the means 5-1 to obtain the variation vector by which the slope vector is 0. A third arithmetic means 5-3 adds the initially estimated state variable vector to the variation vector to obtain the state variable which minimizes the evaluation function. Thus, the state is estimated with fast and stable convergence.

Filed: 1990-03-29
Abstract: PURPOSE:To sharply improve reliability in terms of structural strength by locating a labyrinth part on the inner surface of a casing cover positioned in a portion to divide a lower casing connected to the lower end of an upper casing. CONSTITUTION:Through rotation of a pump shaft 2, a speed gradient is produced in a microgap 21, and a temperature part having low distribution of a specified temperature is provided in a peripheral direction. Even when an amount of injected shaft seal water is low, no forced injection force generated through rotation of the pump shaft 2 is produced, and shaft seal water enters below and smoothly flows in by an amount by which the shaft seal water is pressed in. Namely, shaft seal water of cold water slowly flows in along a labyrinth part 20 located to a casing cover 14 on the static side. This constitution relaxes the change in temperature of the structural material of the labyrinth part 20 responding to a change in an inflow rate and a change in temperature, and reduces a thermal stress generated at the structural material to improve reliability.

Title: Fuel injection quantity controller for internal combustion engine
Inventor: TAKAOKA TOSHIO
IPC: F02D41/06
Filed: 1988-03-31
Abstract: PURPOSE:To prevent the engine stall after the restart at high temperature by controlling the fuel injection quantity by using the lightened value which gently varies for the variation of the actual intake pipe pressure within a prescribed time after the restart at high temperature. CONSTITUTION:A control circuit 44 judges if an engine 20 is within a prescribed time after the restart at high temperature or not. If it is judged that the time is within a prescribed time after the restart at high temperature, the intake pipe pressure detected by a pressure sensor 6 is largely lightened, and the fundamental fuel injection time is calculated on the basis of the lightened value and the engine revolution speed detected by a revolution angle sensor 48. Therefore, even if the actual intake pipe pressure sharply lowers, the lightened value lowered gently, and also the fundamental fuel injection time lowers gently. Therefore, the sharp reduction of the fundamental fuel injection time generated by the lowering of the intake pipe pressure accompanied with the increase of the engine revolution speed after the restart at high temperature is prevented, and the engine stall can be avoided.
