Title: Annealing method for compound semiconductor device
Inventor: FUJII SATORU
IPC: H01L21/265
Filed: 1992-02-27
Abstract: PURPOSE:To provide a method for annealing a compound semiconductor device which has high activity of impurity atom and in which a large quantity of crystal defects do not occur on a surface of a substrate. CONSTITUTION:A rear surface of a semiconductor substrate 1 doped with Si ions on a surface is irradiated with an electron beam. Thus, a distortion 2 is given in a part irradiated with the beam, and a tensile stress in an elastic deformation limit of the substrate is applied to a front surface of the substrate 1. Then, while the substrate 1 remains in this state as it is, the substrate 1 is heated to be annealed in an As atmosphere. In this manner, a lattice interval of atoms of the surface layer of the substrate is extended to weaken the bonding strength between the atoms. In the case of annealing, group III atoms are easily removed with group V atoms to a position between lattices.

Title: Energy-saving device for sewage-purifying plant
Inventor: KIKUCHI SHIYOUHEI
IPC: C02F11/04
Filed: 1981-03-25
Abstract: PURPOSE: To save a consumption amount of fossil fuel in a sewage-purifying plant, by transferring energy, retained in digested sludge discharged from a digestion vessel, to waste matter slurry in a heat exchanger arranged just before the slurry is injected into the digestion vessel.  
     CONSTITUTION: Sluice valves 9, 12 are ordinarily closed, while other sluice valves 10, 11, 13, 14 are ordinarily opened. Sludge introduced through a sludge inlet 2 flows through a heat exchanger 8 into a digestion vessel 1. On the other hand, disgested sludge is discharged from the digestion vessel 1, and carried through a digested sludge-transfer pump 6 and the heat exchanger 8 to a digested sludge outlet 3. In this case, heat is transferred from the digested sludge to the sludge, since there is generally a positive temperature difference between the temperature t d  of the digested sludge and the temperature t' s  of the sludge in the heat exchanger 8. Consequently, the sludge is heated, while the digested sludge is cooled. As a result, the total energy necessary for heating the digestion vessel 1 is reduced to nearly half as that in a conventional manner.
