  • Publication number: 20210116843
    Abstract: A toner container is detachably attachable to a developing device. The developing device includes an inlet to be poured with a toner, an inlet shutter to move between a closed position, at which the inlet is closed, and an open position, at which the inlet is open, a biasing mechanism to bias the inlet shutter toward the closed position, an engaged structure provided in the inlet shutter, an engaging structure to engage with the engaged structure and to retain the inlet shutter at the open position against a biasing force of the biasing mechanism, and an engagement releasing structure provided in the inlet shutter and to release an engaging state between the engaged structure and the engaging structure. The toner container includes a contacting surface to contact with the engagement releasing structure and to make the engagement releasing structure release the engaging state.

  • Publication number: 20210007955
    Abstract: The present invention relates to a cosmetic composition for a keratin substance, for example the skin such as that of the face, comprising: (i) at least one moisturizer; (ii) at least one film-forming polymer; and (iii) a combination of the following fillers: (a) hydrophobic silica: (b) perlite; (c) urethane polymer powder; and (d) acrylic polymer powder. “Long-lasting” effects of a cosmetic composition for a keratin substance comprising at least one moisturizer without creating any dry feeling can be achieved by using both a film-forming polymer and a combination of the following fillers: (a) hydrophobic silica: (b) perlite; (c) urethane polymer powder; and (d) acrylic polymer powder.

  • Patent number: 10648886
    Abstract: In adjustment processing executed at the same period as waveform analysis processing, a CPU of a microcomputer permits an execution of the waveform analysis processing on condition that the waveform analysis processing has been completed. Thus a period of non-execution of the waveform analysis processing is ensured between a completion of preceding waveform analysis processing to an execution of next waveform analysis processing. Since low priority processing, which has been disabled to be executed, is enabled to be executed, it is possible to stop continuation of disablement of execution of the low priority processing.

  • Patent number: 9690231
    Abstract: A toner container includes a container body that is used to house a toner and that is detachably attachable to a mounting portion in a developing device; and an operating member that is used to open and close a shutter. The shutter as well as the operating member includes an engaging portion that can engage with a linking member which is disposed in the mounting portion and which can perform a reciprocating linear movement. In the state in which the container body is not mounted in the mounting portion, the shutter and the operating member are in a non-linked state with each other. In contrast, in the state in which the container body is mounted in the mounting portion, the shutter and the operating member become able to be linked to each other via the linking member.
