  • Patent number: 11001928
    Abstract: In a flow down type surface treating apparatus, a scattering amount of a processing solution is reduced. A film forming mechanism 110 is provided on an inlet side and an outlet side of each treatment chamber. The film forming mechanism 110 ejects a continuous laminar liquid under pressure of about 0.01 MPa at a flow rate of 5 to 10 L/min. Such a liquid film prevents droplets reflected on a surface of an antiscattering member 60 from splashing and entering the adjacent treatment chamber. When a plate-like work 10 is shaken to collide with the liquid film, the film flows down along the plate-like work 10 since the film formed by the film forming mechanism 110 is liquid. Thereby, a shake of the plate-like work 10 is converged. An amount of air flowing in toward a transport direction in each treatment chamber is reduced.

  • Patent number: 10995407
    Abstract: In a flow down type surface treating apparatus, a scattering amount of a processing solution Q is reduced. A honeycomb member 60 is provided vertically below a transport hanger 16. The honeycomb member 60 consists of a plurality of tubular members with hexagonal holes connected together. When the processing solution Q falls in a vertical direction (in the direction of an arrow ?), the processing solution Q passes through through-holes of the honeycomb member 60. When the processing solution Q hits liquid level H, a part of it is reflected. Since a part of the reflected processing solution Q is reflected obliquely, it collides with an inner wall of the through-hole of the honeycomb member 60. As a result, the amount of the treatment liquid Q that emerges again on an upper surface of the through-holes is reduced. Thereby, the honeycomb member 60 exhibits a scattering prevention function.

  • Patent number: 5838154
    Abstract: A magnetic sensor element 1 includes a substrate 10, a conductive layer 12 of a conductive material, and a magnetic layer 11 of a magnetic material, which encloses the conductive layer 12. AC is applied to the element from a drive power source 50, and a detector 60 detects an impedance change due to an external magnetic field. The magnetic layer 11 is bestowed with magnetic anisotropy in a direction orthogonal to the direction of energization of the element 1. With the provision of the conductive layer 12 of conductive material and also with magnetic anisotropy imparted to the magnetic layer 1, the element 1 may be made a low resistivity element. A reactance change and a resistance change of the element due to an external magnetic field change, thus can be effectively detected in drive frequencies two orders of magnitude lower than in the case of a prior art magnetic sensor element.

  • Patent number: 5773728
    Abstract: the present invention provides a force transducer having high compression fracture strength and high detection sensitivity, thus satisfying both detection precision and reliability, and also a method of fabricating such a force transducer. The force transducer is so constructed that a compression force is transferred via a pressure transfer block to narrow strain gages, which protrude from the surface of a silicon substrate and provide a small pressure-bearing area. Therefore, large compression strains act on the strain gages and thus the detection sensitivity is increased. When the compression force exceeds a predetermined value, the pressure transfer block comes into contact with the surface of the silicon crystal, thus improving the fracture strength of the strain gages. These narrow, protruding strain gages can be fabricated easily by a single mesa etching process.

  • Patent number: 5062062
    Abstract: A physical quantity detecting apparatus for detecting a physical quantity of an object of measurement. The position of movement of an object of measurement is divided into a given number of segments in advance. The output of a physical quantity sensor for detecting a physical quantity of the object of measurement is calculated on the basis of a correction operation expression which has an independent coefficient group for each segment so as to correct the offset component and the sensitivity. Thus, a physical quantity such as a transmitted torque is detected with high accuracy at real time without being influenced by the fluctuations of the offset output and the sensitivity depending on the position of rotation. The correction operation may also be performed using the temperature dependence function of the offset signal and the temperature dependence function of the sensitivity, thereby enabling the accurate measurement of the physical quantity without the influence of the temperature change.
