  • Patent number: 10679842
    Abstract: The present invention provides: an InP wafer optimized from the viewpoint of small edge roll-off (ERO) and sufficiently high flatness even in the vicinity of a wafer edge; and a method for effectively producing the InP wafer. The InP wafer having a roll-off value (ROA) of from ?1.0 ?m to 1.0 ?m is obtained by using a method including: performing a first stage polishing under a processing pressure of from 10 to 200 g/cm2 for a processing time of from 0.1 to 5 minutes, while supplying a polishing solution containing bromine to at least one side of an InP single crystal substrate that will form the InP wafer; and performing a second stage polishing under a processing pressure of from 200 to 500 g/cm2 for a processing time of from 0.5 to 10 minutes, provided that the processing pressure is higher than that of the first stage polishing by 50 g/cm2 or higher.

  • Patent number: 10501288
    Abstract: A seal member for sealing a gap between a car-side door sill and a landing-side door sill is slidable between a sealing position and a retracted position and is driven by a link mechanism. The seal member is connected to an actuation spring that receives a movement force toward the sealing position. The link mechanism releases engagement with the actuating member in synchronization with a start of a door open operation of the car door to permit sliding toward the sealing position caused by the actuation spring. The link mechanism is engaged with the actuating member of the car door side in synchronization with movement of the car door toward a door close end to move the seal member to the retracted position resisting to the actuation spring.

  • Publication number: 20170131371
    Abstract: In an MRI apparatus, RF shimming is performed with high precision in a short time irrespective of an object and an imaging mode. A database storing the shim parameter according to a change from a criterion state in advance is included when a state in which an shim parameter is calculated is set as the criterion state of the objet in order to obtain a high-quality image. At the time of imaging, the shim parameter registered in the database in association with a change amount closest to a change amount from the criterion state is used. In the database, the shim parameter calculated from a previously measured result is registered.

  • Patent number: 8462652
    Abstract: In an optical transmission device, firmware that operates within a CPU of a first LIU and firmware that operates within a CPU of a second LIU periodically measure a load status of a CPU via an OS, respectively. Switchover control of a master CPU is performed according to a load status of a CPU measured by the firmware of each LIU. For example, when a load status of the CPU of the second LIU is lower than that of the CPU of the first LIU, a master CPU that performs switchover control of a predetermined port is switched to a slave CPU in the first LIU, and a slave CPU related to the predetermined port is switched to a master CPU in the second LIU, thereby dynamically changing the setting.
