Title: Thermal treatment of gallium arsenide single crystal ingot
Inventor: KAMOGAWA HIROYUKI
IPC: C30B29/42
Filed: 1995-10-16
Abstract: PROBLEM TO BE SOLVED: To provide a method for thermally treating a GaAs single crystal ingot, capable of uniformly annealing even the GaAs single crystal having a large diameter by covering the GaAs single crystal ingot with a heat-insulating material and annealing the ingot. SOLUTION: A GaAs single crystal ingot 15 is inserted into a heat-insulating material 14 comprising a double PBN cylinder formed by inserting GaAs powder 12 between an inner cylinder 10 and an outer cylinder 11, covered with a PBN cap 16, and subsequently annealed. Thereby, the ingot 15 is covered with the heat-insulating material 14. Thus, the volume of the cylinder in the diameter direction is increased, and the gradient of temperature is moderated in an area ranging from the center of the ingot to its periphery. A steep temperature gradient caused by the release of heat on the periphery of the ingot on the cooling of the ingot after the annealing is thereby moderated, and the irregularity of the resistivity in the surface of a wafer is reduced, when the ingot is processed into the wafer.  The thermal treatment especially contributes to the prevention of the lowering of electric resistance at the edge of the wafer. A cylindrical heat-insulating material of felt-like carbon graphite may be used in stead of the PBN cylinder.

Title: Yawing momentum control device for vehicle
Inventor: NAITOU MOTOHIRA
IPC: B60T8/1755
Filed: 1994-10-31
Abstract: PURPOSE: To enhance the convergency of yawing momentum after execution of large angle steering, by detecting an abrupt steering condition when a steering speed exceeds a predetermined value, or when an input by the operator exceeds a predetermined value, and then by compensating the resulted yawing motion so that the yawing motion becomes less. CONSTITUTION: When the steering angle speed θ' increases in a positive direction, exceeding a steering angle speed increasing threshold θ'1 by a steering input at a high speed in a turn increasing direction, a desired yaw rate control flag F1 for compensating a desired yaw rate to a small value, is set from steps S4 to S10 through the intermediary of steps S8, S9.  Since a reference desired yaw rate ψ'0 is never set to '0' unless the reference desired yaw rate becomes less than a previous yaw rate ψ'*(n-1 ) at step S3, the procedure is shifted from step S4 to step S7, and further, by a manipulation input in a turn return direction with some degree, the steering angle θ'2 is decreased in the negative direction while the procedure is shifted from step S7 to step S11 by way of step S12 unless it becomes less than a predetermined steering angle speed decreasing threshold value θ'2 .
