IPC: F01N1/06
Filed: 1987-08-04
Abstract: PURPOSE:To efficiently damp the sound energy by once contracting a sound flux at the inlet part of a reflection chamber formed in the shape of ellipse, and collecting the sound waves reflected on the internal surface of the reflection chamber in a sound-absorbing board arranged at one sound-focusing position of the ellipse. CONSTITUTION:An expansion chamber 6 and a reflection chamber 7 are respectively connected to an inlet pipe 1 in sequence, these chambers are surrounded by an external wall 4, and a face of the external wall 4 touching the reflection chamber 7 is formed in the shape of ellipse. And, an inlet part 8 of the reflection chamber 7 is arranged at one focusing position of the external wall 4 formed in the shape of ellipse, a cylindrical sound-absorbing board 3 being arranged at the other focusing position of the external wall 4 formed in the shape of ellipse. Thus, because the sound flux is once contracted at the inlet part 8 of the reflection chamber 7, and the sound waves reflected on the internal surface of the reflection chamber 7 are connected in the sound-absorbing board 3, the sound energy can be efficiently damped, and the muffling effect can be also improved.

Abstract: PURPOSE:To reduce the cost of electric power in a hot stove, boiler for power generation, etc. by selecting a stage for supplying the privately generated gas to a power generating plant and a stage for supplying said gas to a heat accumulation type heat exchanger according to time zones. CONSTITUTION:The whole or part of the privately generated gas 25 to be supplied to a heat accumulation type heat exchanger of a gas generating installation, hot stove, power generator, etc. is supplied to a power generating plant 26 to increase the generated energy in this time zone and to decrease the purchased electric power. The whole or part of the privately generated gas to be supplied to the plant 26 is supplied to a heat accumulation type heat exchanger 24 to make up the quantity of heat which is not accumulated in the above-described time zone. The decreasing generated energy leads to an increase in the purchased electric power in this time zone. The above-mentioned two forms of supply are selected according to the time zones to reduce the cost of the purchased electric power for the system. Energy is accumulated by using the conventional plant by which the capacity of storing energy in the ironworks is increased.

Title: Partial atomic layer epitaxial method
Inventor: IWAMATSU SEIICHI
IPC: H01L21/268
Filed: 1981-12-10
Abstract: PURPOSE:To permit growth of an epitaxial layer of a partial atomic layer by a method wherein atoms or molecules are partially adsorbed on the surface of a substrate so that a part of atoms or molecular-constituting atoms is coupled to the substrate surface. CONSTITUTION:The surface of an Si substrate 1 containing P is cleaned through plasma in an Ar vacuum container, and chlorine gas is passed to form a Cl adsorption layer 2 on the surface of the substrate 1 at the room temperature. Then, the substrate 1 is heated up to about 100 deg.C, so that only P atoms are converted to PCl3 and evaporated. By passing BBr3 at the room temperature in that state, B forms an adsorption layer 3 together with Br in positions where P atoms have been removed from the surface of the substrate 1. Then, by passing hydrogen on the substrate 1 at the room temperature, Cl, Br, etc. are converted to HCl, HBr, etc. and removed, whereby P atoms are replaced by B atoms which are buried in position where P atoms have existed.

Abstract: PURPOSE:To perform spot knocking operation without being limited by a soft arc conductive film by preparing a bimetal with makes a discharge end interval of a discharge gap smaller as the temperature rises. CONSTITUTION:When a discharge gap 15 starts discharge, once a part of discharge energy is consumed in the discharge gap 15 to raise the temperature of the discharge ends 17 and 18 and to operate a bimetal 19 and make the discharge ends 17 and 18 and to operate a bimetal 19 and make the discharge end interval l smaller so that the existence of the discharge gap 15 in the spot knocking operation can actually be neglected, thus to win the utmost effect through the whole spot knocking hours. The most desirable operation of the bimetal 19 is that in the initial discharge of the spot knocking operation the discharge end interval l is negated, namely, the discharge ends 17 and 18 make direct contact with each other. In said case it means that the discharge gap 15 is not at all existing.
