Title: Titanium dioxide sintered compact, its production and high-temperature member using the same
Inventor: HIRATA TAKEHIKO
IPC: C04B35/645
Filed: 1998-07-02
Abstract: PROBLEM TO BE SOLVED: To obtain the subject sintered compact with improved density and improved corrosion resistance through diminishing its solubility to molten salts, in particular acidic ones such as vanadium-based ones by sintering a pressurized molded form of TiO2 powder at a specific temperature or higher in the atmosphere. SOLUTION: This sintered compact is obtained by sintering a pressurized molded form of TiO2 powder at >=1,200 deg.C in the atmosphere; wherein the TiO2 powder to be used is, e.g. a mixture of TiO2 powder 1.0 μm in average particle size and TiO2 powder 0.2 μm in average particle size. Use of TiO2 which is lower in solubility to acidic molten salts than Al2O3 improves the density of the aimed sintered compact to >=95% and thereby enables the corrosion resistance of the final sintered compact to molten salts to be raised as well. Furthermore, addition of ZrO2 powder at <=5 wt.% to the TiO2 powder raises the resistance of the final sintered compact to vanadium-based molten salts exhibiting especially strong acidity. The surface of a high-temperature member is coated with this TiO2 sintered compact to afford the high-temperature member with high corrosion resistance to molten salts at high temperatures.

Filed: 1985-09-12
Abstract: PURPOSE:To absorb an oscillation generated when activating and stopping a movable mechanism and to prevent the transmission of the oscillation to a disk by disposing a buffer member at least one between a magnet and a yoke or between the yoke and a support base. CONSTITUTION:An oscillating member 14 is disposed between a support base 1 and a yoke 9 and a buffer member is made of, for instance rubber having a prescribed hardness. In such a memory device, the oscillation of a drive mechanism 12 according to a reaction when activating and stopping a movable mechanism 11 is absorbed by the buffer member 14 disposed between the support base 1 and the drive mechanism 12. Thereby, the oscillation generated in the drive mechanism 12 is prevented from being transmitted to a disk 3. A buffer member 16 is disposed between a yoke 15 and a magnet 10, thereby, the oscillation generated when activating and stopping the movable mechanism 11 is absorbed by a drive mechanism 17 consisting of the yoke 15 and the magnet 10.

IPC: B21J13/10
Filed: 1987-08-18
Abstract: A forging manipulator has two pairs of workpiece gripping arms which operate in respective mutually perpendicular planes. Each pair of arms is operable by a respective independent actuating mechanism, so that the respective pairs of arms can accommodate workpiece dimensions. The two actuating mechanisms comprise: a common bore in the gripper carrier of the manipulator, defining two co-axial fluid pressure cylinder disposed end to end, a respective annular piston in each of these cylinders, a respective hollow piston rod extending from each piston towards the gripper arms, one of these piston rods extending within the other piston rod, and a respective wedge at the forward end of each piston rod, for operating the corresponding pair of gripper arms on movement of the piston rod. The wedges slope in opposite directions, and the pistons move simultaneously in opposite directions. This provides a very compact construction and allows material and tools to be delivered to and removed from the manipulator from the rear through the hollow piston rods.

Title: System for avoiding isolated packet exchange
Inventor: IHARA TADASHI
IPC: H04L45/28
Filed: 1988-08-15
Abstract: PURPOSE:To prevent the control of a packet exchange from being disabled by releasing the block of a line already blocked and setting newly a logic information line if no path to set the logic information line exists. CONSTITUTION:Suppose that a relay line L12 is blocked and a logic information path setting section U1 of a packet exchange P1 sets a logic information path R2, then if a line block instruction is sent from a network management equipment N to a packet exchange P1 to block a relay line L13, the packet exchange P1 blocks the relay line L13. Then the logic information path setting section U1 is going to select other relay line, since no available relay line exists, the block of the relay line L12 blocked already is released automatically to set the logic information path R1. Thus, even if the network management equipment blocks all the relay lines in error, the disabled control of the relevant packet exchange is prevented.
