  • Patent number: 10529882
    Abstract: A method for manufacturing a multi-junction photoelectric conversion device includes forming a first electrode on a first photoelectric conversion unit including a first semiconductor layer as a photoelectric conversion layer, the first electrode including a plurality of patterned regions separated from one another by separation grooves; and eliminating a leakage existing in the first semiconductor layer by applying a reverse bias voltage between one of the patterned regions of the first electrode and a second photoelectric conversion unit comprising a second semiconductor layer as a photoelectric conversion layer. The application of the reverse bias voltage is performed while irradiating the second photoelectric conversion unit with light, generating a photocurrent in the second photoelectric conversion unit that is larger than a photocurrent in the first photoelectric conversion unit.

  • Publication number: 20180266908
    Abstract: A sensor sheet is manufactured by forming a conductive heat-sensitive material 5 over first wiring electrodes 3a and forming second wiring electrodes 4a over the conductive heat-sensitive material 5. For this reason, no adhesion surface (boundary surface), which is formed when adhesion is performed later, exists between the first wiring electrode 3a and the conductive heat-sensitive material 5 and between the conductive heat-sensitive material 5 and the second wiring electrodes 4a.

  • Patent number: 9274185
    Abstract: A method for judging a coercive force of a magnetic recording medium, so recording magnetic information can be formed in either a low coercivity magnetic medium or a high coercivity magnetic medium by using a magnetic head. A magnetic information recording step writes magnetic information in the magnetic recording medium by alternately using a first write current suitable for writing in the low coercivity magnetic medium and a second write current suitable for writing in the high coercivity magnetic medium. A magnetic information reproducing step reproduces the magnetic information written in the magnetic recording medium. A judging step makes a judgment on a coercive force of the magnetic recording medium by way of comparing a first reproduced output A of the magnetic information written with the first write current and a second reproduced output B of the magnetic information written with the second write current.
