Title: Heat exchanger utilizing geothermal heat
Inventor: YAMANASHI TAKASHI
IPC: F24J3/08
Filed: 1980-06-02
Abstract: PURPOSE: To perform a heat exchanging operation through the utilization of geothermal heat by a method wherein a pipe made of a high heat conductivity and having an inner pipe therein is embedded underground.  
     CONSTITUTION: The pipe 1 is made of a material of high heat conductivity and is embedded in the ground 2. The inner pipe 6 is arranged within the pipe 1 and communicates with a water feed hole 5. When the hot water from a water feed pipe 20  is flowed through the water feed hole 5 in summer, the hot water flows down to the lowermost portion of the inner pipe 6 and then flows upward while it is agitated to take swirling motions by an agitation inducing hole 8 of a retaining plate 7, so that the hot water is cooled by the geothermal heat through the pipe 1 and flows from an outlet hole 9 as cold water. On the other hand, when cold water is flowed through the feed water hole 5 in winter, hot water flows out from the outlet hole 9 in the like manner as in summer.

Abstract: PURPOSE:To suppress carrier flow into a semiconductor substrate by connecting a diffusion layer to an external terminal and supplying an isolation area and a semiconductor substrate with potential which is reverse direction bias. CONSTITUTION:An N<+> diffusion layer 104 is formed on a P well 103, an external terminal 105 and an internal circuit are formed and both are connected to a MOS transistor 106.

Title: Vapor growth method for semiconductor
Inventor: TERAO HIROSHI
IPC: H01L21/205
Filed: 1982-05-04
Abstract: PURPOSE:To obtain a fixed quantity of a raw material supplied at low cost and simply and completely, and to improve stability during the growth of a semiconductor vapor growth layer by detecting a temperature of the raw material under a liquid state, feeding the result back to a transport gas flow regulator and controlling the quantity of supply per unit time of raw- material vapor. CONSTITUTION:The quantity of supply per unit time of the raw material is decided by the product of vapor pressure determined by the temperature of the raw material and the flow rate of a gas for transport. When the temperature of the raw material changes, the quantity of supply per unit time of the raw material can be made constant when a vapor-pressure change corresponding to a temperature change is obtained and the flow rate of the gas for transport is adjusted. Since the relationship of the temperature changes of the raw materials and the vapor- pressure changes is obtained accurately in response to each raw material, the temperatures are detected, vapor pressure corresponding to the changes is acquired, and an electric circuit for setting the flow rate of the gas for transport making the quantities of the raw materials supplied constant is easily obtained finally. The quantities of the raw materials supplied are made constant instantaneously because the response time of a mass flow controller is short. A simple circuit may be used because the vapor-pressure changes are regarded as rectilinear when the temperature changes are within approximately + or -2 deg.C particularly. The quantities of the raw materials supplied can be made constant at all times in principle however the temperatures of the raw materials change.

Further, the repairing to the damage part of the furnace inner wall is easily executed and the service life in the blast furnace is extended.
