Inventor: FUJISAWA HIDEO
IPC: C30B11/00
Filed: 1998-11-17
Abstract: PROBLEM TO BE SOLVED: To suppress the defective coating of the diameter increasing part of a crucible and to obtain a single crystal in a high yield by disposing a B2O3 material on the bottom of the crucible and melting it by heating to coat the surface of the wall of the crucible. SOLUTION: A hollow conical B2O3 material 5 is disposed so that it adheres to the lower tapering part 10 of a crucible 1. Preferably a polycrystalline material 4 such as GaAs, GaP, InP or ZnSe is tightly filled into the conical hollow part so as to surely coat the tapering part 10 with B2O3 when the B2O3 material 5 melts. A truncated conical polycrystalline material 4 is most preferably used. A vertical boat method is adopted as a crystal growth method and a crystal is grown, e.g. by a VB method by which a crystal is solidified by varying the relative position of the crucible 1 and a furnace while keeping a constant temperature gradient or a VGF method by which a crystal is solidified by controlling the temperature of a heater while fixing the furnace.

Abstract: PURPOSE: To detect a two-dimensional pattern of a distribution of the force applied by a tire by means of an array type group of load sensors and to compute and display a tire pressure on the basis of computer analysis. CONSTITUTION: A group of sensors 2 are arranged in a pit liner buried in a roadway 10, and their sensing areas 6 are covered by an elastic layer 8. The advancing direction for a vehicle is indicated by an arrow 12. When the vehicle moves on the group of sensors 2, outputs from the respective sensors are changed along with the elapse of time, and on the basis of these data, a mean contact pressure and a quasi pressure can be computed. On the basis of a time interval from the time when the vehicle starts covering the sensors to the Lime when the vehicle leaves the sensors, a vehicle speed can be decided. On the basis of the respective signals, which are changed along with the elapse of time, from the group of sensors 2, a two-dimensional pattern is found so as to be inputted into a neural network constructed in a computer.  As the network previously learns representative number and form of a tire and a vehicle, a tire pressure can be estimated.
