Title: Noise reducer
Inventor: OGAWA SUMIO
IPC: F01N1/00
Filed: 1991-09-05
Abstract: PURPOSE:To reduce a noise satisfactorily as suppressing power consumption in the generation of a ripple in a noise reducer in which a ripple with negative phase is superimposed on the noise generated in a fluid path. CONSTITUTION:A diaphragm 8 to supply the ripple to exhaust gas in the exhaust path 1 of an internal combustion engine is fixed on one terminal of a lead spring 10. The leaf spring 10 is supported between a pair of supporting rollers 14 mounted on a movable member 12 for leaf spring supporting. An excitator 16 is assembled in the movable member 12. The position of the movable member 12 is controlled so as to conform the proper frequencies of the diaphragm 8 and the flat spring 10 to the primary frequency of an exhaust noise due to the explosion and burning of an engine main body. The excitator 16 excites the diaphragm 8 so as to be set at the frequency equivalent to the primary frequency component of the noise and also at the negative phase. Amplitude can be amplified by the resonance of an excited diaphragm 8.

IPC: G03F1/68
Filed: 1989-08-31
Abstract: PURPOSE:To reduce the strain of a mask pattern formed by patterning an X-ray absorber film by installing a control electrode having holes for passing ion particles between a target and a mask substrate, applying voltage to the control electrode and controlling the ion particles rebounded from the target entering the mask substrate. CONSTITUTION:Ar gas is introduced while evacuating the inside of a chamber 13 from an exhaust port 19, and power is applied between a base plate 14 and a cathode 16 by a DC power 17. The voltage of a control electrode 20 is brought to -50V. Consequently, Ar gas is ionized at a positive value, and is attracted to the negative voltage of the cathode 16 and collides with a target 15 composed of tantalum, and the metallic particles of tantalum driven out are deposited on the foundation film 23 of a mask substrate 22a oppositely faced to the target. On the hand, Ar ions colliding with the target 15 are rebounded to return to the mask substrate 22a, and the movement of Ar ions is promoted by the control electrode 20. Accordingly, the quantity of Ar ions entering among the columnar crystals of an X-ray absorber film (a tantalum film) 24 is augmented, increasing the component of compressive stress in the X-ray absorber film 24 and offsetting tensile stress, thus stress generated in the X-ray absorber film 24 is reduced extremely.

Title: Shell and tube heat exchanger
Inventor: NUMATA MITSUHARU
IPC: F28D7/16
Filed: 1996-08-28
Abstract: PROBLEM TO BE SOLVED: To miniaturize the size of a heat exchanger that is necessary for attaining predetermined supercooling and to enable attaining high efficiency by arranging resistance means in the flow dividing part of heating medium. SOLUTION: A part with a higher flow velocity of inflow water from an inlet tube 44 is decelerated as a punching plate 60 that induces resistance to the flow of water is arranged to a heat exchanger 50 in the inner most part of a flow dividing part 40. The ununiformity of velocity distribution inside the flow dividing part 40 is reduced. That is, the drift is reduced. Therefore the velocities of water that flows through the inside of each of the heat exchanger tubes 49 become almost equal and the difference of temperature among paths is hardly caused. So, the supercooling state of water will not become unstable when the water that goes through each of the heat exchanger tubes 49 merges at a merging part 41. The supercooling state is not dissolved easily so that the degree of the supercooling of the water can be increased more than before.  With this, the size of the heat exchanger that is necessary for attaining the predetermined supercooling can be miniaturized and the high efficiency can be attained.

IPC: G01S7/34
Filed: 1984-10-31
Abstract: PURPOSE:To remove a time measuring error due to the variation in a pulse signal wave by increasing the rising ratio of an envelope, by reducing the amplifying gain of the pulse signal wave from the point of time when the transmitted pulse signal wave reached a set reference level. CONSTITUTION:When a transmission order signal Tc is inputted, a 'H' signal A is outputted from a trigger circuit 2 up to the point of time when the arrival of a pulse signal wave R is estimated and, next, a signal B is outputted from a gate circuit 3 at the falling of the signal A to set FF10 and a signal C is outputted. By this mechanism, an integration circuit 11 is operated and voltage VD rising with the elapse of a time is outputted and drop voltage VE is outputted corresponding thereto from a subtraction circuit 12 and the gain of an amplifying circuit 6 gradually increases while voltage comparators 7, 9 are operated by the signal B. Next, when the voltage VR of the amplified signal wave R becomes larger than voltage VS, a signal ZCS is outputted and, when VR<VS is formed, FF10 is reset by a signal ZC. Voltage VE rises as voltage VD drops and amplifying gain is reduced.

Abstract: PURPOSE:To obtain an accurate focusing state in a short time by calculating the amount of overrun of a lens as the function of a target amount of movement, and correcting the target amount of extent on the basis of the amount of the overrun. CONSTITUTION:The amount of overrun of a motor can be made to correspond to the target amount of movement as shown in a graph.
