Title: Sprinkler head
Inventor: HATTORI KOSEI
IPC: B05B1/26
Filed: 1997-11-14
Abstract: PROBLEM TO BE SOLVED: To uniformly sprinkler fire fighting water extending over a wide area by providing a turbulance forming means in an outflow hole of a head main body, and positioning the lower end side outer peripheral surface of a support piece of a deflector inside the outer peripheral circle formed by the outer peripheral surfaces of the respective water sprinkling plates. SOLUTION: An annular body 4 is provided in the lower part side inner peripheral surface of an outflow hole 3, and as the inside diameter of the outflow hole 3 is suddenly enlarged by the enlarged diameter part 3b, the stream of fire fighting water is turbulent. Since the speed distribution of such a turbulence is substantially uniform as compared with that of a laminar flow, the fire fighting water collides with the upper surfaces of the deflector main body and the plug body 5 substantially equally. Accordingly, the fire fighting water flows radially without deviation to the water sprinkling plate side.  As the lower end side outer peripheral surface of a support piece is positioned inside the outer peripheral circle formed by the respective outer peripheral surfaces of the water sprinkling plates, the fire fighting water colliding with the inner peripheral surfaces of the water sprinkling plates flows into the lower end outer peripheral surface side of the support piece to be sprinkled outward. Thus, fire fighting water is uniformly sprinkled extending over the whole periphery.

Abstract: PURPOSE:To obtain a high-speed arithmetic processing unit which can be easily packaged into a VLSI in a comparatively simple circuit constitution, by forming a partial computing element for addition or subtraction, etc., in the form of a combination circuit of an array structure having a small number of elements. CONSTITUTION:A subtraction shift type divider contains plural stages of the quotient deciding circuits 81-88 which decide the digits of the quotients from the partial residues and the partial residue deciding circuits 120-170 which decide the partial residues after the digits of the quotients are obtained. Then the output signals of the circuits 81-88 of the preceding stage are added to the signal showing the lowest rank digit of a divisor 40 for decision of the second lowest digit of the partial residue of each of circuits 120-170. Thus a deciding circuit is omitted for the lowest rank digit of the partial residue of each of circuits 120-170. Thus it is possible to reduce the hardware quantity and also to increase the arithmetic processing speed.

IPC: F23N5/24
Filed: 1994-11-24
Abstract: PURPOSE: To correct the fluctuation of the sensor output of a CO sensor due to a specific heat change during switching of combustion capacity of a burner. CONSTITUTION: Correction data of a CO sensor 21 according to a specific heat change occasioned by the change of an air ratio in exhaust gas during combustion at combustion capacity of each stage of a burner is prestored at a memory 27. A sensor output correction part 26 receives a sensor output from the CO sensor 21, determines a specific head change changed through switching of combustion capacity of a burner, corrects a sensor output by utilizing correction data of the memory 27 by an amount equivalent to the specific heat change, and a corrected sensor output value is added to a CO safety part 24. The CO safety part 24 performs CO safety operation by using the corrected sensor output value.  When, though the specific heat of exhaust gas is changed by switching combustion capacity of the burner, CO density in exhaust gas is unchanged, the value of a sensor output applied on the CO safety part 24 is kept at an unchanged value through correction operation of a sensor output correction part 26, reliability on CO safety operation is improved.
