Title: Liquid fuel combustion device
Inventor: HIRATA YASUSHI
IPC: F23D11/40
Filed: 1984-03-08
Abstract: PURPOSE:To restrict an accumulation of tar in a gasification surface, in particular a striking surface and to provide a superior combustion by a method wherein a projection is formed at the gasification surface near the terminal end of a circulation flow at the side surface of the gasification chamber in a liquid fuel combustion device for a gasification and premixing combustion in which petroleum to be applied in a home-use heating equipment or the like is applied as fuel. CONSTITUTION:A projection 9 is formed at a gasification surface near a terminal end of a circulation flow at the side surface of a cylindrical gasification chamber 1 having a bottom part to be heated by a heater or the like. Fuel injected from a fuel nozzle 6 is directly struck against a striking surface 7a. The striking surface 7a is located in an area of film boiling condition, so that almost all of the fuel is not gasified at the striking surface 7a, it is dispersed as smaller particles and the dispersed fuel particles are gradually gasified under a film boiling condition at another gasification surface 7 while being circulated. Then, the fuel particles not being gasified are struck against the projection 9 again, divided again and further dispersed as more fine particles, resulting in generating a condition in which the fuel may easily be gasified and then it is gasified at the gasification surface 7. Further, a gasification load of the fuel at the striking surface 7a is excessively decreased, and since the fuel is in a hot temperature range, tar may not be generated and accumulated at the striking surface 7a.

Title: Manufacture of compound semiconductor device
Inventor: KAJIMURA TAKESHI
IPC: H01L29/93
Filed: 1984-03-08
Abstract: PURPOSE:To enable to strictly control the respective thickness of the lowresistance layers and to obtain stably the various characteristics of a compound semiconductor device by a method wherein the compound semiconductor device is constituted including two processes of a process, wherein one side of the low-resistance layers is formed on the high-resistance layer formed on the substrate in the same conductive type as that of the high-resistance layer, and a process, wherein the other side having a conductive type inverse to that of the one side the low-resistance layers is formed on the one side of the low-resistance layers. CONSTITUTION:A high-resistance N type epitaxial layer 2 is formed on a low-resistance N type GaAs substrate 1 by a vapor-phase growth method, and after that, an ion-implantation is performed using Si and so forth as impurities, and following that, a low-resistance N type layer 3 is formed in a prescribed thickness by performing an annealing. The thickness of this ion-implanted layer can be precisely controlled by controlling the impurity dose and the accelerating voltage. Moreover, as the annealing to be performed for activating the implanted ions can make the ions activate at comparatively low temperatures, the depth of the implanted layer is not changed excessively. As a result, the thickness of the low-resistance N type layer can be easily obtained as indicated in the design value. Then, a low-resistance P type layer 4 is formed by a vapor-phase epitaxial growth method. This formation can be formed at 900 deg.C or thereabouts. When the low-resistance P type layer is formed, there is some shift of impurities, but the amount is a small amount and as the P type layer is formed at comparatively low temperatures, the thickness can be sufficiently controlled.

Abstract: PURPOSE:To prevent an acoustic wave lens from contacting a sample by providing an air bearing for scanning the acoustic wave lens and sample relatively, and detecting the air pressure of the air bearing and controlling the blowing of air. CONSTITUTION:The acoustic wave lens 3 is fitted to an exciting plate 1, which is supported by the air bearing 7. The air bearing 7 is provided with air outlets 7a-7c. The acoustic wave lens 7 and sample 9 are moved relatively to make a two-dimensional scan, thereby picking up an ultrasonic wave image. AT this time, when the focusing positions of the acoustic lens 3 and sample 9 are determined, an abutting preventive tool 4 for the acoustic wave lens 3 prevents the acoustic wave lens 3 from contacting the sample 9. Further, the supply pressure from the air outlets 7a-7c to the exciting plate 1 varies owing to the contacting between the abutting preventive tool 4 and sample 9. The pressure is detected 6 and the blowout of air from the air outlets 7a-7c is controlled to elevate the exciting plate 1 momentarily, thereby preventing the sample 9 from damaging instantaneously. Thus, the acoustic lens 3 and sample 9 are prevented from contacting each other and an observation is made efficiently.
