Title: Manufacture of light emitting element
Inventor: AIDA HIROYUKI
IPC: H01L33/16
Filed: 1988-02-04
Abstract: PURPOSE:To realize a method of forming a uniform concave hemisphere on the surface of a chemical compound semiconductor by a method wherein an amorphous semiconductor film whose refractive index is equal to that of the semiconductor substrate is formed on the substrate, and the surface of the semiconductor film is processed to be formed into a concave lens form. CONSTITUTION:A planar luminous type light emitting element provided with a hemispherical lens formed on a light take-out face of a semiconductor substrate 1 of the light emitting element is manufactured in such a manner that an amorphous semiconductor film 4 whose refractive index is equal to that of the semiconductor substrate 1 is formed on the substrate 1, and the surface of the semiconductor film is formed into a convex lens form by processing. For instance, an alpha-Si film 4 is laminated on the InP substrate 1 of the light emitting diode, which is formed into a hemispherically processed face 6 by processing. When the alpha-Si film is processed through a liquid phase chemical etching, a smooth hemispherical face can be formed as the processing free from the effect caused by a crystalline face. The reason that alpha-Si is selected as an amorphous semiconductor film is that its refractive index is nearly equal to that of InP or 3.40 and consequently an optically adverse effect is not generated.

IPC: B41J2/325
Filed: 1990-02-05
Abstract: PURPOSE:To prevent the white streak or density lowering of a recorded image by decoding image signals received each time when a predetermined quantity of image signals are received and acting the same on the ink sheet fed by an ink sheet feed means to record an image on a recording medium. CONSTITUTION:An ink sheet 14 is fed by a 1/n line and, continuously, recording paper 11 is fed by one line (1/15.4mm). Next, a current is supplied to one block of the heating resistor 132 of a thermal head 13. Then, it is investigated whether or not a current is supplied to the blocks of all of the heating resistors 132 of the thermal head 13 and, when the supply of a current to all of the blocks is not completed, the current supply processing of the next block is taken after the elapse of a current supply time. When image data are received at every unit blocks (several lines) and an image is recorded while the data are decoded, the feed quantity of the ink sheet to the recording paper is reduced at the recording time of the first line of the next block after the final line of the block is recorded to perform recording. By this method, the white streak generated between the blocks of the formed image or the lowering of image density of the head of the blocks can be prevented.

Title: Heat accumulating device
Inventor: ISHII TAKAHITO
IPC: F28D20/02
Filed: 1982-02-17
Abstract: PURPOSE:To improve the heat transfer and heat radiating properties of the title device by a method wherein a latent heat type heat accumulating material and a vaporizable heat transfer medium having a specific gravity higher than that of the heat accumulating material in a fused state are sealed into a solar heat accumulation tank used for hot water heating operation and heat transfer medium condensed by a heat transfer medium condenser provided in the unoccupied space in the tank is circulated through the heat accumulating material. CONSTITUTION:When the heat accumulation tank 5 is heated, the heat transfer medium 7 having a high heat transfer efficiency heats to an elevated temperature by adsorbing heat so that the heat accumulating material 6 is heated to melt and accumulates heat while the heat transfer medium 7 becomes saturated vapor to fill the tank 5. Thus, when water 10 is supplied into the tank 5 at the time of heat radiation, the vapor of the heat transfer medium 7 condenses to heat the water 10. The condensed heat transfer medium 7 is then collected in a shielded vessel 8 and returned to a section B filled with the heat accumulating material 6. In this case, the heat transfer medium 7 precipitates in the heat accumulating material 6 since the specific gravity of the latter is higher than that of the former and during the above process, the heat transfer medium 7 vaporizes again to move upward. Consequently, the heat accumulating material 6 is agitated to become crystallized without being overcooled and without the occurrence of phase separation and releases its latent heat of fusion.
