  • Patent number: 11734098
    Abstract: A non-transitory computer-readable recording medium stores a failure cause identification program for causing a computer to execute a process including: collecting process information related to one or more processes that operate in a container environment; obtaining a derivative relationship of a process for each container on the basis of the process information; generating symbol information in which a function of each of the processes is associated with a container in which each of the processes operates according to the derivative relationship of the process for each container; generating an aggregation result in which a frequency of the function is aggregated according to the symbol information; and identifying a cause at a time of failure occurrence on the basis of the aggregation result.

  • Publication number: 20220409109
    Abstract: To dramatically develop a technology for determining a mental and physical state of a subject by observing temporal dilation and contraction of a pupil in response to stimulus light, an eye of the subject is irradiated with stimulus light for 0.5 second under a state in which the pupil of the subject is not adapted to darkness. The pupil of the subject becomes smaller and then larger than the size at the time of irradiation with stimulus light. When the size of the pupil of the subject 5 seconds after the moment of irradiation with the stimulus light is larger than the size of the pupil at the moment of irradiation with stimulus light, a determination system determines that the subject is in a state in which a sympathetic nerve is dominant over a parasympathetic nerve.

  • Patent number: 11495906
    Abstract: A connector assembly comprises a connector and a mating connector. The mating connector comprises a mating housing. The mating housing is formed with a release projection. The connector comprises a first housing and a second housing. The first housing is provided with a stopper. The second housing is provided with a stopped portion. One of the first housing and the second housing is provided with a second support portion which supports a supported portion. When the second housing is installed to the first housing, the stopped portion is brought into abutment with the stopper, and a movement of the second housing is regulated by the stopper. When the thus-regulated second housing is received into the mating housing together with the first housing, one of the second support portion and the supported portion is brought into abutment with the release projection so that the regulation of the second housing is released.

  • Publication number: 20220269520
    Abstract: A non-transitory computer-readable recording medium stores a program for causing a computer to execute a factor identification process, the factor identification process includes detecting an occurrence time point when a system call of a host operating system (OS) has occurred, acquiring switching operation information that enables an environment switching time point to be identified, the environment switching time point being a time point when an environmental process has switched, the environmental process implementing a software execution environment which is in operation on the host OS and is isolated from the host OS, identifying, based on the switching operation information, a first environmental process which is in operation on the host OS at the occurrence time point, and outputting the first environmental process in association with the system call.

  • Patent number: 10978817
    Abstract: A substrate-mounting connector includes a housing, a contact mounted to the housing, and a shield shell. The shield shell includes a first plate and a second plate disposed adjacently. A part of the first plate serves as a first contact portion. A first extension piece is formed in the second plate. A part of the first extension piece serves as a second contact portion. A part of the housing serves as a pressing portion facing the first plate, in a covering state in which the shield shell is mounted to the housing. A part of the first plate, different from the first contact portion, or a part of the first extension piece, different from the second contact portion, serves as a pressed portion pressed by the pressing portion in the covering state. The pressing portion presses the pressed portion to make the first contact portion contact the second contact portion.

  • Publication number: 20190000309
    Abstract: It is an object to provide an inexpensive technology capable of alleviating pain of a patient during phlegm suction. A laryngeal camera unit (200) is used in combination with a portable device including a lens, which forms a part of a camera, and a light. The laryngeal camera unit (200) includes an illumination light transmission member (223) and an image light transmission member (222), both of which are rod-shaped and are to be inserted in an oral cavity. Illumination light from the light of the portable device is transmitted to a larynx by the illumination light transmission member (223), and image light from the larynx is transmitted from behind a uvula to the portable device by the image light transmission member (222). A user performs the phlegm suction while checking an image displayed on a display of the portable device.
