Patent JP-S5938598-A (JP)
Title: Plate type heat exchanger
Inventor: NIKAI ISAO
IPC: F28F3/06
Filed: 1982-08-27
Abstract: PURPOSE:To intend to improve performance of exchanging heat, by providing a heat transmitting promotor to the part of a flow path of a heat exchanger other than a cross flow part, in a heat exchanger having a cross flow part so as to be designed to flow fluids having different temperatures, directly crossed to each other, at the outlet of the fluid. CONSTITUTION:Turbulent flow promotors in order to disturb the flow of fluid, twisted strips 3, for example, are inserted into the flow path of the fluid only on the high temperature side and the low temperature side of the counter-flow path 2, along the longitudinal direction of the flow paths. The said twisted strips 3 are fixed to plates or partition walls of a heat exchanger. When the fluids on the high temperature side and the low temperature side flow into the counter-flow part respectively, the flow of these fluids are disturbed because of the existence of the twisted strips 3. By these turbulences, the temperature boundary layer which is the resistance to transfer heat is decreased, and the heat transfer rate between the fluid and the solid surface inside of the flow path can be increased, accordingly, the heat transfer rate of a heat exchanger can be increased. By promoting heat transfer in such a manner, 1/50-1/20 out of total heat exchanged calorific value is absorbed into the cross flow part 1 in the above- mentioned form of a heat exchanger and under the temperature condition, so that the difference in temperature at the outlet of fluid can be suppressed down to the range at 5-15 deg.C.

Title: Air control valve device
Inventor: TAMAKI SHIGEO
IPC: F02D9/00
Filed: 1994-06-30
Abstract: PURPOSE:To suppress the occurrence of displacement in a position of a coupling member even when the clearance of a bearing part is increased by a method wherein a coupling member on the throttle position sensor side is formed in an arcuate shape of a plate, a circular member is pressed in a hole formed in the direction of the diameter of a valve stem in a coupling member on the throttle valve stem side, and the two coupling members are brought into contact with each other. CONSTITUTION:A bearing member 17 pivotally supporting a throttle valve shaft 16 is worn owing to use for a long time and a clearance set at an initial stage is increased. In this case, when idling is applied, the negative pressure of an engine is exerted on a throttle valve body 18 and displacement in a position occurs by a clearance amount. A throttle position sensor 1 is rotated in synchronism with the rotary shaft of a sensor. In this case, a member 11 in a circular shape is pressed in a hole formed in the direction of diameter in the end of a throttle valve shaft 16, and the outer diameter part of the circular member 11 is brought into contact with a protrusion member 12 on the sensor side for coupling. Since the part, making contact with the circular member 11, of a protrusion member 12 on the sensor side is formed in an arcuate shape, even when a position making contact is displaced, a rotation amount of the throttle valve stem 16 is kept at a constantly specified value.

Abstract: PURPOSE: To obtain the titled heavy oil of good quality, capable of giving a hydrating ratio always stabilized without influence of atmospheric temperature, and having a stabilized combustion state, by heating heavy oil and water separately before entering an emulsifier, and feeding both kept at a specific temperature into the emulsifier.  
     CONSTITUTION: A heavy oil from a service tank 1 is passed through an oil transporting pipe 2 by the suction with a pump 7, heated by a heater 5, set at a desired flow rate by a flow rate regulator 6 and fed into an emulsifier body 14. On the other hand, water fed from a water supply pipe 8 is passed through a pressure regulator, set at a pressure of 0.6W1.2kg/cm 2 , heated by a heater 11, adjusted and set at a desired mixing ratio to the heavy oil by a flow rate regulator 12 and joined to the oil transporting pipe 2 at a joining point 13. The resultant mixture of the heavy oil with water is then fed into the emulsifier body 14 to divide water finely, uniformly diffuse into the oil and give the aimed emulsion of the heavy oil. The joining and contact temperature of the water with the heavy oil is set at 40W70°C.

Abstract: PURPOSE:To reduce the size of a diameter and to decrease the number of parts by installing a light source in the vicinity of a first focal point of an elliptic reflecting mirror, and by installing a concave lens whose focal point is almost identical with a second focal point, between the elliptic reflecting mirror and its second focal point. CONSTITUTION:A filament 3a of a halogen bulb 3 is situated on a first focal point f1 of an elliptic reflecting mirror 2, while a concave lens 4 whose focal point is identical with a second focal point f2 is installed between the elliptical reflecting mirror 2 and the second focal point f2. A periphery of the concave lens 4 is fitted in an opening end limb of the elliptic reflecting mirror 2. The light that is reflected at the elliptic reflecting mirror 2 and is directed to the second focal point f2 passes the concave lens 4, being directed forward as a parallel light, whereby, curvature of the elliptic reflecting mirror 2 being altered in every part, a required light distribution pattern can be obtained. The reduction of the size of a diameter can be achieved thereby without reducing effective quantity of light. Also, a guide cylinder, etc., is not needed, and the number of parts can be reduced.

Abstract: PURPOSE:To shorten operation time when a divisor is a power of 2 by selecting either the output of a division circuit or the output of a shift circuit in accordance with the output of a power of 2-detection circuit detecting that the divisor is a power of 2. CONSTITUTION:The division circuit 3 calculating the quotient and a remainder from the given divisor and a dividend, the power of 2-detection circuit 6 detecting that the divisor is a power of 2, and the shift circuit 4 shifting the dividend right by the number of bits corresponding to the divisor are provided. The selection circuit 7 selects either the output of the division circuit 3 or the output of the shift circuit 4 in accordance with the output of the power of 2-detection circuit 6.

Title: Water quality control system and water quality control method
Inventor: HENMI YUKIO
IPC: G21D1/00
Filed: 1997-06-06
Abstract: PROBLEM TO BE SOLVED: To prevent an insoluble corrosion product from being adhered to equipment and pipes and to prevent a differential pressure from increasing and the concentration rate of an impurity from increasing by preventing, for example, chemicals that cause environmental problems from being used and suppressing the occurrence of a corrosive product and properly eliminating it. SOLUTION: Corrosion resistance against the local or entire surface corrosion of a system material is improved, and the generation of an oxide being accelerated due to corrosion and the adhesion of the insoluble corrosion product of a main iron constituent are suppressed, thus improving the increase in a differential pressure. Further, an oxide film being formed on a material surface is reinforced due to the control of metal ions in terms of water quality, thus obtaining cumulative effect and hence reducing the corrosion of the material.  In this manner, the selection of the system material including surface treatment is made and the optimum design of a purification system is performed, thus efficiently controlling water quality without using chemicals that may adversely influence the environment and obtaining an inexpensive boiler system and cooler system with less need for maintenance and a high material reliability.

Of the image signals of R, G and B outputted from the color camera 7, e.g. G is made to be a defect reference image and B is made to be an illuminance-distribution reference image. The signals are inputted into an image processing device 8. The illuminance distribution of the illuminance-distribution reference image is subtracted from the illuminance distribution of the defect reference image.
