Title: Latent heat type heat accumulating device
Inventor: YAMASHITA KAZUO
IPC: F28D20/02
Filed: 1983-04-26
Abstract: PURPOSE:To obtain stable, high temperature heat exchange output by a structure wherein latent heat type heat storage material, heat transfer medium, which is practically non-compatible with said heat storage material and changes itself from liquid to gas by absorbing heat and from gas to liquid by releasing the heat again, and foam, the apparent specific gravity of which is smaller than that of the heat storage material, are sealed in a heat storage tank under the condition that a space is left at the upper portion in the interior of the heat storage tank. CONSTITUTION:A heat accumulating device consists of heat exchangers 5 and 6 and a heat storage tank 2, which is provided with heat insulating layer and in which heat storage material 3 such as trihydrosodium acetate salt, heat transfer medium 4, which is non-compatible with the heat storage material 3 and has larger density, such as Freon 113, and foam 9, the apparent specific gravity of which is smaller than that of the heat storage material 3, such as ceramic foam, are sealed. When low temperature heat transfer medium is flowed in the heat exchanger 6 under the condition that the heat accumulating device 1 is at the state that enough heat is stored, the heat storage material filled in the tank 2 is stirred by the evaporation- condensation cycle of the heat transfer medium 4 and at the same time the heat transfer medium 4 release its heat at the heat exchanger 6 by heat-exchanging. At this time, the temperature in the space above the heat storage material filled in the tank 2 drops. However the temperature drop at the upper part of the heat storage material is prevented by the existence of the layer of the foam 9, which is onto the upper part of the heat storage material filled in the tank because of its density being smaller than that of the heat storage material.

Title: Method for controlling steam flow rate
Inventor: MASUDA SHUICHI
IPC: H01L21/31
Filed: 1998-03-23
Abstract: PROBLEM TO BE SOLVED: To precisely and easily control the flow rate of steam supplied to a diffusion furnace in steam generated in an outer fuel device, by controlling the discharge pressure of a process flow and the discharge pressure of a discharge flow so that the process flow becomes a prescribed flow rate. SOLUTION: The pressure ratio of an exhaust pressure controller for process gas 6 and an exhaust pressure controller for steam 7 is decided in accordance with the flow rate of steam as process gas and the flow rate of steam discharged through the exhaust pressure controller for steam 7. A signal from a mass flow meter for steam is inputted to a mass flow controller for steam 8 and the pressure ratio of the exhaust pressure controller for process gas 6 and the exhaust controller for steam 7 is controlled by the signal. Thus, the amount of steam supplied to a diffusion furnace from an outer fuel device can precisely and easily be controlled. Then, the life of the outer fuel device can be prolonged.

Abstract: PURPOSE:To provide a power DMOS semiconductor device with which the current detection accuracy of DMOS at a detection part can be improved remarkably without extension of a manufacturing process. CONSTITUTION:A ring-shaped well region 43, which is formed on the surface of a semiconductor substrate 1 by doping the impurities for a well region, is formed independent of the main well region 41 and the sub-well region 42 wherein the sub-well region 42 is surrounded by the above-mentioned ring-shaped well region 43 through a prescribed interval thus relaxing the electric field on the surface of the substrate 1.

Filed: 1994-04-13
Abstract: PURPOSE:To enhance the flowability of the waste ink in a waste ink transmission means and to reduce the operation time of an emission recovery means by providing a ink compatible yarn like member in the waste ink transmission means. CONSTITUTION:When waste ink is intermittently stagnated in a tube 12, stagnated waste ink droplets remain as stagnated ink 43 by surface tension. By providing an ink compatible yarn like member 42 in the tube 12, the stagnated ink 43 is expanded along the ink compatible yarn like member 42. As a result, the ink is prevented from remaining in the tube 12 so as to form a meniscus and, even when suction recovery operation is continuously performed, the negative pressure driving of a pump 11 is effectively performed because the flowabillty of the ink in the tube 12 is good.
