摘要:
A control device for controlling a steer-by-wire steering control device includes a switch mechanism for detaching a main motor and transmitting a rotation of a sub motor to establish a failsafe mode in which a turning is possible. A first control device controls a reactive force actuator and the sub motor. A second control device drives a main motor. The first control device has an abnormal case switch command unit and, when receiving a result of diagnosis that the main motor fails to operate properly, or when the mutual trouble diagnosis unit diagnoses that the second control device is in a trouble, the switch mechanism is set to the failsafe mode.

A dental composition of the present invention includes: a polymerizable monomer component (A); and an amorphous filler (B) having an average particle size of 1 to 20 μm and including silica-based fine particles and coatings of an oxide that cover the surfaces of the silica-based fine particles. The oxide contains a zirconium atom, a silicon atom, and an oxygen atom. The dental composition contains 20 to 500 parts by weight of the filler (B) per 100 parts by weight of the polymerizable monomer component (A). The dental composition has a viscosity of 10 to 800 Pa·s. It is preferable that the filler (B) contain spherical particles, and that the percentage of the spherical particles in the filler (B) be at least 60%.

A kit for bonding to biological hard tissues, containing a phosphorylated polysaccharide, a polyvalent metal salt other than phosphates, and a solvent. The adhesive composition for biological hard tissues provided by the kit for bonding to biological hard tissues is suitably used in for medical uses, such as cement for bones or dental cement. In addition, since the adhesive composition has excellent bio-absorbability, it is useful as fusion materials for artificial joint prosthesis, fusion materials for spine fracture, fusion materials for extremity fracture, filling materials for bone tumors in the region of orthopedics, filling materials and restorative materials at dental caries-defective sites, luting materials for prosthetic restorative materials such as inlay and crown, pulp-capping and lining materials, implant surface treatment materials, periodontal disease therapeutic materials, hyperesthesia preventive materials, dental pulp capping materials, substrates for DDS, substrates for systems engineering, and tissue bonding materials in the dental region.

摘要:
In a computer including a processor for executing a program and a storage that includes a first storage area and a second storage area for storing objects generated by the executed program, the processor stores objects generated by executing the program in the first storage area. If an object stored in the first storage area is accessed, the processor records access information of the accessed object. The processor extracts a leak object having a high possibility of memory leak on the basis of the recorded access information, and moves the extracted leak object to the second storage area.

The device includes a rolling bearing unit supporting a radial load and a magnetic bearing unit supporting an axial load and/or a bearing preload; an electromagnet fitted to a spindle housing so as to confront, on a non-contact basis, a flange shaped thrust plate mounted on a main shaft; a motor rotor of a motor for driving the shaft, and a motor stator opposed to the rotor, the shaft being driven by magnetic or Lorentz forces developed between the rotor and the stator; and a sensor detecting an axial force acting on the bearing unit, and a controller controlling the electromagnet. In this device, the stiffness of a composite spring formed by the bearing unit and a support system for the bearing unit is chosen to be higher than the negative stiffness of a composite spring of a motor part comprised of the electromagnet and the motor.

When a program execution unit of a computer executes a creation instruction of objects utilized by an execution target program in process of executing the execution target program, the program execution unit disposes a created object in an internal heap when a life period of the created object is not contained within life period of objects for root class and gets average value of life time corresponding to set of objects to which the created object belongs with reference to memory allocation information table to dispose the created object as a long-life object in an external heap when the gotten average value of life time is equal to or larger than a predetermined value. Accordingly, life time of objects is measured and long-life objects are not managed by GC, so that program utilizing objects can be executed at high speed.
