  • Patent number: 9692019
    Abstract: To provide an element manufacturing method and element manufacturing apparatus for efficiently manufacturing an element such as an organic semiconductor element. First, an intermediate product, which includes a substrate and a protrusion extending in a normal direction of the substrate, is formed. Next, the intermediate product is covered, at a side where the protrusion is provided, with a first surface of a lid member. After the covering of the intermediate product, a gas is injected into an enclosed space formed at a side of a second surface of the lid member that is present on an opposite side of the first surface. This enhances an internal pressure of the enclosed space, thus bringing the first surface of the lid member into close contact with the intermediate product.

  • Patent number: 9680098
    Abstract: An element manufacturing method and apparatus for efficiently manufacturing an element such as an organic semiconductor element. First, an intermediate product that includes a substrate and a protrusion extending in a normal direction of the substrate is provided. Next, in a stacking chamber conditioned to a vacuum environment, a stacked structure is formed by continuously stacking a lid member on the intermediate product at a side where the protrusion is provided. After this operation, the stacked structure is transported from the stacking chamber to a first pressure chamber coupled to the stacking chamber and conditioned to a first pressure higher than the pressure in the vacuum environment. Next, the stacked structure is further transported from the first pressure chamber to a separation chamber coupled to the first pressure chamber and conditioned to a vacuum environment, and then the stacked structure is separated into the intermediate product and the lid member.

  • Patent number: 9592572
    Abstract: An element manufacturing method in which a section of a substrate that is irradiated with laser light can be covered efficiently. A plurality of protrusions of an intermediate product are lined up in a first direction on a substrate, and a sealing mechanism includes one pair of rollers that rotate around a rotational axis extending in a second direction orthogonal to the first direction. The paired rollers are lined up spacedly in the first direction. In a sealing step using the sealing mechanism, a section of a lid member that is being tensioned between the paired rollers is in close contact with a part of the intermediate product. In an irradiation step, light passes through the section of the lid member that is being tensioned between the paired rollers, and reaches the intermediate product.

  • Patent number: 9086444
    Abstract: Provided is a magnetic field detection device and a current sensor capable of increasing the degree of freedom in selecting the type of the magnetic field detection element. A magnetic field detection device 1 includes a conductor 3 that generates a magnetic field; a C core 2 provided so as to surround the conductor 3; and a magnetic field detection element 4 that detects a magnetic field. The C core 2 has a gap G1, and the magnetic field detection element 4 is disposed at a position where the magnetic field generated from the conductor 3 can be detected, the position being outside the gap G1. Since the direction of the magnetic flux varies outside of the gap G1 from place to place, the direction of the magnetic flux that passes through the magnetic field detection element 4 can be arbitrarily selected by arbitrarily selecting the installation location of the magnetic field detection element 4. Therefore, the degree of freedom in selecting the type of the magnetic field detection element 4 is increased.
