  • Publication number: 20210166549
    Abstract: A power supply device is such that when an output voltage is abnormal, a system manager or the like can easily acquire information effective in identifying a cause of the abnormality. The power supply device includes a first light emitting element installed to be visually recognizable from an exterior, and a light emitting element control unit that drives the first light emitting element. When an output voltage is abnormal, the light emitting element control unit causes the first light emitting element to flash, thereby convert at least one of specific power supply operation information used for inferring a cause of the output voltage being abnormal and cause information inferred based on the specific power supply operation information into an optical digital signal formatted for serial communication, and causes the optical digital signal to be output from the first light emitting element.

  • Patent number: 10617712
    Abstract: One solid preparation of the present invention mainly includes silicon fine particles, and has a capability of generating hydrogen. In addition, one specific example of the solid preparation mainly includes silicon fine particles having a crystallite diameter principally of 1 nm or more and 100 nm or less, and exhibits a capability of generating hydrogen in an amount of 3 ml/g or more when brought into contact with a water-containing liquid having a pH value of 7 or more. In this solid preparation, hydrogen is generated when the silicon fine particles are brought into contact with a water-containing liquid having a pH value of 7 or more. Therefore, taking advantage of the characteristics of the solid preparation, generation of hydrogen is promoted in, for example, a gastrointestinal tract where the pH value is 7 or more due to secretion of pancreatic fluid after passage through the stomach after oral ingestion.
