IPC: F23N5/00
Filed: 1981-12-19
Abstract: PURPOSE:To improve the combustion efficiency of a combustion controller by controlling the fuel flow rate control valve in response to the sum of the outputs of a proportional integrator and differentiator which inputs an output hot water  temperature and the deviation between the hot water temperature and the  target temperature and controlling the rotating speed of a fan motor in response to the output of the proportional integrator. CONSTITUTION:In a hot water supplying device, when a cock is opened, a fan motor 12 and a solenoid change over valve 3 are sequentially operated by a combustion sequence control circuit 15. Simultaneously, the deviation between the outputs of a water temperature sensor 11 and a target temperature setter 17 is obtained by a deviation detector 18, and the output of which is applied through a proportional integrator 19 and a differentiator 20 to an adder. Then, the valve opening of a flow rate control valve 5 is adjusted through a valve drive circuit 21 by the sum of both the integrator and differentiator 19, 20. At this time, the output of the integrator 19 is inputted to a fan motor speed control circuit 22, the output of the integratr 19 is discriminated at level in plural stages, thereby operating the switching element 21, and stepwisely varying the rotating speed of the motor 12.

Title: Semiconductor integrated circuit device
Inventor: FURUSAWA KAZUNORI
IPC: G11C16/06
Filed: 1985-09-20
Abstract: PURPOSE:To hold the electric potential of a common source line almost at a fixed level by forming a control voltage signal corresponding to a difference between the potential of the common source line and a fixed voltage to control the conductance of a MOSFET in a variable resistor element connected between the common source line and the earth potential of the circuit. CONSTITUTION:When the electric potential of the common source line CS increased by a large writing current flow into the common source line CS on the basis of all-bit writing or the like in a chip selecting state, the source potential of a MOSFET Q17 is increased in accordance with the rise of said potential and a constant voltage Vr is supplied to the gate of the MOSFET Q17. Thereby, the conductance of the MOSFET Q17 is reduced and its output voltage is increased by reducing the the voltage difference between the gate and source. Such kind of an amplified signal is furthermore amplified by inverter circuits IV1, IV2, so that a control voltage Vc is boosted and the inductance of a MOSFET Q10 is increased. Consequently, the voltage drop is held almost at a fixed potential independently of the increase of the writing current.

Abstract: PROBLEM TO BE SOLVED: To obtain an equiinterval distance-measuring ruler by which equal intervals can be distance-measured and entered simply and by which a straight line passing a point can be drawn precisely by a method wherein equiinterval entry holes by distance and a groove for straight-line drawing are formed on the ruler. SOLUTION: Ordinary graduations are set on a ruler 1 in such a way that their long direction is horizontal. Graduations are marked sequentially in the vertical direction from 1 mm. Equiienterval entry holes 22 by distance are formed at equal intervals in the horizontal direction at every distance. In addition, a groove 3, for straight-line drawing, in a width of 0.5 mm is formed on the ruler 1 in the horizontal direction. When the ruler 1 is used so as to put distance-measuring points at an interval of, e.g. 2 mm, the drawing holes 2 in a position of 2 mm in a vertical graduation are thrust sequentially so as to be entered. At this time, it is sufficient to perform an operation mechanically, it is not required to do mental arithmetic, and it is not required to concentrate a nerve on an operation to read out a measuring point from the ruler so as to be entered precisely.  In addition, when a straight line passing a point is drawn, the groove 3 for straight-line drawing is used, and the straight line is drawn by applying the ruler 1 in such a way that the point is in the center between both side faces of the groove 3.

Abstract: PURPOSE:To decompose efficiently a noxious exhaust gas containing a combustion sustaining special material gas component by mixing an amount of a reaction- accelerating gas to be required for decomposing the combustion-sustaining gas contained in the exhaust gas with the exhaust gas to permit combustion reaction to be carried out. CONSTITUTION:A noxious exhaust gas containing a combustion sustaining special material gas is introduced into a mixing part 1 through an exhaust gas introducing pipeline 13 in a state of laminar flow under extremely low pressure and, simultaneously, a reaction-accelerating gas such as hydrogen is also introduced into the mixing part 1 through a reaction-accelerating gas introducing pipeline 14, and both the gasses are then led to a combustion region part 3. On the other hand, when a combustion supporting gas stream flowing in a combustion-improving gas flow portion 4 at high speed reaches a connection port 7, this gas stream meets the mixed gas flowing at low speed at the combustion region part 3. Accordingly, part of the combustion sustaining gas enters the connection port 7 and abuts against the side wall of the combustion region part 3 at a portion 16 of the connection port 7 to flow centrifugally and spirally in a direction as shown by the arrow 17. By this method, the combustion reaction of a combustion sustaining gas component can be carried out efficiently.
