  • Publication number: 20240091792
    Abstract: A display screen 100 of an operation panel displays: a function (130) that gives notification of the performance of a periodic inspection of a cooling system; and an operation button 131 for starting inspection of the cooling system. During an easy inspection, a compressor 9a of the cooling system 9 is activated when a rotor 5 is not installed, it is determined whether the temperature detected by a temperature sensor 12 falls to a prescribed temperature (e.g., ?3° C.) within a prescribed period of time (e.g., within 10 minutes) from activation, and the cooling system is determined to be normal if the detected temperature falls to the prescribed temperature and abnormal if not. The results of the determination are stored at a storage unit of the centrifuge, the timing 132 of the next inspection is displayed on the display screen 100, and it is possible to reference a past inspection history.

  • Patent number: 7974668
    Abstract: Guiding pieces on a bracket cover is engaged with attachment claws on a bracket body. This engagement serves to hold the bracket cover on the bracket body when the bracket cover is set at a first position. When the bracket cover is set at a second position, the engagement between an engagement piece and a hook piece serves to cooperate with the engagement between the guiding pieces and the attachment claws so as to hold the bracket cover on the bracket body. The bracket cover is firmly held on the bracket body when the bracket cover is set at the second position. The bracket cover is thus reliably prevented from detachment from the bracket body.

  • Patent number: 7859591
    Abstract: A camera module unit includes a printed wiring board overlaid on a shielding enclosure. A camera module is supported on the surface of the shielding enclosure. The camera module is located inside a recess defined in the printed wiring board. A shielding metal plate covers over the camera module. An elastic piece is defined in the shielding metal plate. The elastic piece is resiliently received on the surface of the shielding enclosure. The shielding metal plate realizes a sufficient shielding for the camera module in the camera module unit. Electric current is allowed to easily run from the charged shielding metal plate to the shielding enclosure through the elastic piece. The camera module is supported on the shielding enclosure inside the recess. The height of the camera module is reduced above the printed wiring board.

  • Patent number: 7673998
    Abstract: An enclosure assembly allows a hinge bracket to realize establishment of the opened attitude or the closed attitude of a second enclosure relative to a first enclosure. The second enclosure rotates relative to the hinge bracket around the second rotation axis. The second enclosure in this manner changes its attitude relative to the first enclosure. The hinge bracket stays where it is. The hinge bracket does not rotate. The position of the light sources is thus kept unchanged. The position of the light is maintained regardless of a change in the attitude of the second enclosure around the second rotation axis. The enclosure for an electronic apparatus is thus allowed to enjoy an enhanced appearance. This leads to an enhanced appearance of the electronic apparatus.
