Title: Automatic steering device for vehicle
Inventor: SAKAI KATSUHIRO
IPC: B60W30/00
Filed: 1999-06-22
Abstract: PROBLEM TO BE SOLVED: To prevent large load from working on a steering actuator performing automatic steering control. SOLUTION: This steering device drives a steering actuator so that an actual steering angle θ may meet a reference turning angle θref set for the traveling distance of a vehicle, and stops automatic steering control if a deviation E of the reference turning angle θref from the actual turning angle θ is a prescribed value or over (step S9). By stopping the driving of the steering actuator when the vehicle speed is zero even if the deviation E is less than the prescribed value (step S8), it is possible to prevent the steering actuator from being overloaded by static steering and perform automatic steering control positively even with a small and inexpensive steering actuator with little power consumption.

Title: Method for building hearth of electric furnace
Inventor: SAKUMA HITOSHI
IPC: F27D1/04
Filed: 1992-06-11
Abstract: PURPOSE:To minimize the area for which the refractory brick needs repairing and facilitate the replacement of the brick in building d a hearth laying refractory bricks for the bottom of an electric furnace, by using refractory, each block of which is trapezoid in section with a wider plane at the bottom and juxtaposing such blocks in concentric circles in building a hearth. CONSTITUTION:On the inner side of the bottom of a furnace shell 1 with a bottom pouring nozzle 3 at the center a hearth is formed by juxtaposing in concentric circles around the center of the furnace bricks 2 each of which is trapezoid in section with a wider plane at the bottom. With an electric furnace built of this refractory brick, the fusion loss of the refractory brick, caused by the melting operation, is usually seen to be conspicuous in the middle of the furnace and the damage abates with expansion of the concentric circles toward the periphery. Therefore, the repair work only needs removing the bricks showing fusion loss in concentric circles and replacing them with new refractory bricks. The space requiring the repair can be reduced to the minimum. The shape of a trapezoid with a wider bottom also serves to ease the handling and enables effecting the repair work efficiently.

Title: Electroviscous fluid
Inventor: OGAWA KEITA
IPC: C09K23/54
Filed: 1988-07-14
Abstract: PURPOSE:To provide a stable electroviscous fluid without causing the phase separation in storage by using a silicone oil modified by polyether or epoxy polyether as a dispersing agent for said electroviscous fluid. CONSTITUTION:In the electroviscous fluid containing a dispersed phase consisting of a water absorptive silicate such as silica gel and zeolite, a liquid phase consisting of a nonconductive, hydrophobic liquid such as dimethyl polysiloxane and a dispersing agent, the silicone oil modified by polyether or epoxy polyether is used as its dispersing agent. Since such modified silicone oil indicates a good compatibility with either a hydrophilic or hydrophobic liquid phase, the dispersion stability of the dispersed phase is increased and the phase separation is controlled. Therefore, a high stability of the subject fluid is maintained over an extended period of time.
