  • Publication number: 20140061455
    Abstract: In accordance with an embodiment, a method of adjusting quality of an image of patterns common in shape includes acquiring a first gray value and a first waveform within a reference image, acquiring a sample image, acquiring a second gray value and a second waveform from third and fourth regions within a sample image, respectively, and adjusting the brightness and contrast of the sample image. The first gray value is a standard for the brightness of the image from a first region within a reference image. The first and second waveforms represent a luminance profile of second and fourth regions including edges, respectively. The third and fourth regions correspond to the first and second regions. The brightness and contrast of the sample image are adjusted by matching the first gray value and the first waveform with the second gray value and the second waveform.

  • Patent number: 8172041
    Abstract: A machineroom-less elevator in which a counterweight is vertically moved behind a cage, with the cage and the counterweight being suspended in a jig back manner through a first and second diverting sheaves. In this machineroom-less elevator, a sufficiently large vertical stroke of the counterweight can be secured, while a durability of a hoist rope is improved. In addition, since no tensile difference is generated in respective parts of the hoist rope, vertical vibrations of the cage are prevented when the cage restarts a vertical movement. A traction sheave is disposed on one of right and left sidewalls of an elevator shaft. A first diverting sheave is disposed below and sufficiently apart from the traction sheave, and a second diverting sheave is disposed on a top of a rear wall of the elevator shaft.

  • Publication number: 20090236725
    Abstract: An electronic component having a semiconductor element bonded to a substrate with solder has a decreased bonding strength if there is not a suitable clearance between the semiconductor element and the substrate. Therefore, a solder preform having high melting point metal particles dispersed in solder has been used in the manufacture of electronic components. However, when an electronic component was manufactured using a conventional solder preform, there were cases in which the semiconductor element leaned or the bonding strength was not adequate. A solder preform according to the present invention has a variation in the size of high melting point metal particles which is at most 20 micrometers when the metal particle diameter is 50 micrometers, and an alloy layer of the high melting point metal particles and the main component of solder is formed around the high melting point metal particles. In addition, no voids at all are present in the solder.

  • Patent number: 7562745
    Abstract: An elevator in which a driving apparatus, a traction sheave, and a counterweight-side rope hitching portion are arranged above one rail of the right and left cage-side guide rails, while a cage-side rope hitching portion and a speed governor are arranged above the other rail of the right and left cage-side guide rails. Since a control panel is arranged along a rear inner wall surface of the machine room, a large operation space can be secured in a center part of the floor of the machine room. Further, since a machine beam can be extended at full length in the back and forth direction in the machine room, no additional building-side receiving beam is needed.

  • Publication number: 20090014092
    Abstract: [Problems] A conventional process for producing a solder preform in which a predetermined amount of high-melting metal particles are directly put into molten solder and stirred, requires a long time for dispersing the high-melting metal particles by stirring. Therefore, in the conventional method for producing a solder preform, dissolution of the high-melting metal particles into the molten solder occurred during stirring, and their particle diameters became small. If a semiconductor chip and a substrate are soldered with a solder preform containing metal particles having such decreased diameters, the space between portions being soldered becomes narrow, and a sufficient bonding strength is not obtained. [Means for Solving the Problems] In the present invention, a premixed master alloy having a higher proportion of the high-melting metal particles in solder is first prepared, then the premixed master alloy is put into molten solder to disperse the high-melting metal particles.
