  • Publication number: 20220287922
    Abstract: A dentin regenerative cell culture that can bring about a rapid regeneration of dentin in a deficit region. In the treatment of a tooth using the dentin regenerative cell culture, a root canal where a pulpectomy has been performed is filled with a root canal filler containing dental pulp stem cells. The dentin regenerative cell culture is then implanted in the deficit region of dentin, and temporary sealing with a packing is carried out. The dentin regenerative cell culture is formed three-dimensionally in conformity with the shape of the deficit region with the coalescence of cell masses of a plurality of odontoblasts, and thus the dentin regeneration is well promoted. In addition, gaps between the dentin regenerative cell culture and biological tissue can be rapidly filled. Infection due to bacterial infiltration can thereby be prevented.

  • Publication number: 20220216746
    Abstract: An electric tool includes an AC motor (an electric motor) and a control unit. The AC motor includes a permanent magnet and a coil. The control unit is configured to perform control on operation of the AC motor. The control performed by the control unit includes field weakening control. In the field weakening control, the control unit causes a flux-weakening current to flow through the coil. The flux-weakening current is a current that generates, in the coil, a magnetic flux that weakens a magnetic flux of the permanent magnet.

  • Patent number: 11193584
    Abstract: For a hybrid vehicle including an engine, a motor generator, and a belt-type continuously variable transmission, a controller performs a low speed position return expediting control in response to a downshift request accompanying deceleration. During the low speed position return expediting control, the controller increases a differential pressure between a primary pressure and a secondary pressure and cause a downshift toward a lowest speed position transmission ratio by reducing the primary pressure, and further reduces the primary pressure when the secondary pressure becomes greater than or equal to a trigger threshold value during the downshift; and terminates the low speed position return expediting control when an actual secondary pressure decreases to a secondary pressure minimum level. The controller further sets a secondary pressure lower limit higher than the secondary pressure minimum level during the low speed position return expediting control.

  • Patent number: 10783470
    Abstract: A schedule management system 1 having isolators 3 (production facilities) and a main control device 4 for managing a production schedules of all the isolators 3. The production process of each isolator constituting the production schedule has a plurality of sub-processes, the production status being determined in the sub-process. The main control device 4 adds a new separating operation to the passage process and performs an update when the main control device 4 obtains a determination result that the separation of cells in a separation state confirmation operation (sub-process) in the passage process is insufficient while a passage process for cells A is being carried out in the isolators. The main control device 4 alters the start time of a culture medium exchange process for other cells B different from the updated passage operation, and updates the production schedule.

  • Patent number: 10400206
    Abstract: A sterile work can be applied by a worker 29 to cells or the like through a glove 28 provided in an isolator 15. A work headset 31 outputting a work procedure of the sterile work vocally is prepared for the worker, and a check input device 39 is prepared for a checker 36. A management device 12 outputs the work procedure of the sterile work this time vocally to the work headset. When the fact that the worker has normally performed the sterile work this time is checked by the checker, and when the fact is input from the check input device to the management device, the management device performs the subsequent work procedure. Since the sterile work by the worker 29 can be monitored by the checker 36, a wrong work can be prevented from being performed.

    Abstract: A bone marrow fluid of a patient is sampled, housed in a collection tube 11 and conveyed into an isolator in a sterile state. In the isolator, the bone marrow fluid in the collection tube is pipetted into test tubes and culture tube, etc. To the bone marrow fluid in the tubes, an erythrocyte sedimentation agent is added. After precipitating erythrocytes, the supernatant is collected. From the collected supernatant, a bone marrow cell-containing fraction for liver regeneration is concentrated and pipetted into flasks which are conveyed into an incubator to start the cell-culture. From the isolator system, test tubes are taken out. The bone marrow fluid in the test tubes and the concentrate are subjected to a safety test, etc.
