Title: Excess heat generating method by ac current heavy water electrolytic decomposition
Inventor: KOYAMA NOBORU
IPC: G21B3/00
Filed: 1993-11-25
Abstract: PURPOSE:To expedite electrolysis by applying a non-steady stimulus to deuterium and to generate stable excess heat for a long time by superposing a sine AC of a predetermined amplitude on a DC current to an applying current, and so applying it that a heavy water occlusion rate is always varied. CONSTITUTION:Electrolyte 2 made of heavy water is contained in an electrolytic cell 1, and a palladium rod cathode 3 of hydrogen occlusion metal and an anode 4 made of a platinum wire around the cathode 3 are dipped in the cell 1. An applying current in which a sine AC is superposed on a DC current is applied to the cathode 3, a state of deuterium near a surface of the electrode 3 is dynamically and periodically varied. Further, an amplitude and a period of the AC component are altered, the deuterium in the electrolyte 2 is set to a non-steady state to be occluded to hydrogen occlusion metal of the cathode 3, and excess heat upon occluding is efficiently generated. Deuterium gas and oxygen gas generated in the cell 1 are converted to heavy water with a catalyst 5 made of platinum wire with palladium black. Thus, generation of the excess heat can be stabilized for a long period.

Title: Dry etching method
Inventor: SHIMADA KATSUTO
IPC: H01L21/302
Filed: 1990-11-22
Abstract: PURPOSE:To make the vertical etching step feasible for simplifying the manufacturing prosses by a method wherein, in order to dry etch the compound semiconductor region on a semiconductor substrate, the thickness of a photoresist is made larger than the etching depth of the semiconductor region. CONSTITUTION:A GaAs substrate 101 is coated with a photoresist 102. At this time, the thickness of the resist 102 is made larger than the etching depth or the substrate 102. Next, a square pattern is formed by photolithographic step and then the substrate 101 is dryetched away by reaction ion beam etching step using chlorine gas. At this time, since the thickness of the resist 102 is made larger than the etching depth of the substrate 101, the processing section perpendicular to the substrate 101 can be formed. Through these procedures, only one layer of the resist 102 will suffice for a mask so as to simplify the manufacturing processes of a semiconductor device thereby making the vertical etching step feasible.
