Title: Ultrasonic flowmeter
Inventor: AKIYAMA CHIYUUJI
IPC: G01F1/66
Filed: 1984-06-29
Abstract: PURPOSE:To measure flow rate at a high accuracy by a method wherein an ultrasonic pulse is transmitted to and received from a fluid of a pipeline and the received signal is compared with a comparison voltage to transmit an output pulse while the comparison voltage is decided optimally. CONSTITUTION:A pulse B is transmitted from an ultrasonic transmitter 5 and transmitted 3 to or received 4 from the flow of a fluid F of a pipeline 1 alternately varying the direction thereof by changing a selector switch 7. Then, the received signal H and a comparison voltage Vc from a D/A converter 10 are inputted into a comparator 9 and the part of the wavefrom surpassing the comparison voltage Vc is outputted as pulse output P. At this point, different reference voltages are outputted sequentially as comparison voltage Vc with a control circuit 14 to compute the size thereof with respect to the pulse output P thereby determining the optimum comparison voltage Vc. Then, the pulse output P is inputted into an arithmetic circuit 11 to determine flow rate from time difference between the pulse output P and the start pulse S of an ultrasonic pulse. Thus, the optimum comparison voltage can be determined with the control circuit though the amplitude of the ultrasonic pulse is almost constant thereby enabling highly accurate measurement of the flow rate.

Title: Sewage filter
Inventor: YOSHIDA TADAHIRO
IPC: B01D24/02
Filed: 1995-05-31
Abstract: PURPOSE: To provide a sewage filter in which excellent filter performance of floating materials is maintained over a long time and the time required for backwashing is shortened. CONSTITUTION: An upper filter bed 3 of a filter bed body 2 is packed with filter mediums 3a each consisting of three small cylinders combined integrally in parallel to each other and each small cylinder is provided with a clearance (t) opened outward and having 12-20mm outer diameter D and length L and 1.05-1.15 specific gravity. A lower filter bed 4 thereof is packed with filter mediums 4a each having the same shape as the filter medium 3a and whose small cylinder has 3-8mm outer diameter D and length L and 1.3-1.5 specific gravity. Since the void of these filter mediums 3a, 4a is large, the upper filter bed 3 and the lower filter bed 4 continue to catch large floating materials and small floating materials over a long time, respectively.  Since the small cylinders are each provided with the clearance (t), a floating material such as hair and a fibrous one is easily eliminated from the filter mediums 3a, 4a by flow due to backward washing.

Title: Production of dispersion-strengthened heat-resistant sintered alloy
Inventor: DOI YOSHIHIKO
IPC: C22C1/05
Filed: 1985-06-21
Abstract: PURPOSE:To easily obtain the titled heat-resistant sintered alloy having improved mechanical strength and high-temp. strength by compacting the dispersion-strengthened powder which is mechanically compounded and alloyed at the Solvus temp. of a gamma' pohase or below then subjecting the powder to superplastic working and further to recrystallization annealing and heat treatment. CONSTITUTION:The dispersion-strengthened powder described above is compacted by a working method such as hot hydrostatic press, hot press or forging at the Solvus temp. of the gamma' phase or below. A preform having about >=95% alloy density and <=10mum average crystal grain size is thus obtd. The preform, i.e., the dispersion- strengthened alloy having the fine crystal grains is subjected to >=70% superplastic working at low-stress and low-strain strength and is then subjected to the recrystallization annealing to form the coarse grains having >=500mum average crystal grain size. The alloy having the increased average crystal grain size is subjected to the heat treatment and the dispersion-strengthened heat-resistant sintered alloy having the improved mechanical strength and high-temp. strength is obtd. The process for production of this invention exhibits a particularly remarkable effect with the Ni-, Co- or Fe-base oxide dispersion-strengthened ultra-heat-resistant alloys.

Abstract: PURPOSE:To keep a proper air-fuel ratio and perform complete combustion of the fuel even if the fuel supply decreases as a result of the delivery port of a fuel feed nozzle being narrowed, by installing a means for detecting a change in fuel supply amount and a means for controlling air supply amount to a burner device. CONSTITUTION:In operation of a burner device 4, a fuel pressure on the downstream side from an orifice 31 of a fuel supply passage 14 is detected by a pressure detector 32, the result is inputted to a solenoid valve control circuit 37 of a controller 26 to compare it with the set pressure of a reference value memory circuit 38 by means of a comparator 39, and the result is fed to the burner device 4 to detect a change in an actual fuel amount. When a nozzle is brought to narrowed condition and a fuel amount is decreased, below the set value, the fuel pressure exceeds the reference value, and a difference is produced between two pressure signals inputted to the comparator 39. Thereby, an H-level signal is outputted from said comparator 39 to change a solenoid valve 33 into operating condition (in that an air feed passage 16 is throttled), and the air amount for combustion fed to the burner device 4 is decreased for correction corresponding to the fuel amount to keep the air-fuel ratio in a proper range.
