A toner container information acquiring method includes: measuring a toner amount contained in a resin forming a toner container; and acquiring information regarding mechanical strength of the toner container based on the measured toner amount.

A cartridge detachably attachable to an apparatus body of an image forming apparatus that forms an image on a recording medium in which a memory unit is fixed by an inexpensive adhesive member that can control adhesion force. The cartridge includes: a memory; and a memory support member that supports the memory. The memory has a semiconductor device storing information related to a cartridge, a sealing material that protects the semiconductor device, and a cartridge electrical contact configured to be electrically connectable to a body electrical contact of the image forming apparatus body for transferring information on the semiconductor device to the image forming apparatus body. The sealing material and the memory support member contain the same type of a thermoplastic resin, the sealing material and the memory support member have bonding faces, and at least parts of the bonding faces are welded and fixed by a solvent.

Systems and methods relating to accurate Channel State Information (CSI) measurements for a License Assisted Secondary Cell (LA SCell) are disclosed herein. In some embodiments, a wireless device enabled to operate in a cellular communications network according to a carrier aggregation scheme using both a licensed frequency band and an unlicensed frequency band operates to determine whether a Channel State Information Reference Symbol (CSI-RS) transmission from a LA SCell of the wireless device is present in a subframe, where the LA SCell is in an unlicensed frequency band. The wireless device further operates to process a CSI-RS measurement for the LA SCell for the subframe upon determining that a CSI-RS transmission from the LA SCell is present in the subframe and refrain from processing a CSI-RS measurement for the LA SCell for the subframe upon determining that a CSI-RS transmission from the LA SCell is not present in the subframe.

Systems and methods relating to accurate Channel State Information (CSI) measurements for a License Assisted Secondary Cell (LA SCell) are disclosed herein. An exemplary user equipment enabled includes a transceiver, at least one processor, and memory containing instructions executable by the at least one processor whereby the user equipment operates to detect whether a downlink control information (DCI) message indicating that a Channel State Information Reference Symbol (CSI-RS) transmission from an LA SCell of the user equipment is present in a subframe. When the user equipment detects that the DCI message indicates that a CSI-RS transmission from the LA SCell is present in the subframe, it processes a CSI-RS measurement. When the user equipment detects that the DCI message does not indicate that a CSI-RS transmission from the LA SCell is present in the subframe, it refrains from processing the CSI-RS measurement.

A drum cartridge includes a blade, a sheet metal member, a support member, and a fastening member. One of the sheet metal member and the support member includes a first center hole which is formed at a center portion, and a fastening member receiving portion formed at a first end side and configured to fasten the fastening member. The other of the sheet metal member and the support member includes a second center hole which is formed at the center portion, and a through hole which is formed at the first end side and through which the fastening member is passed. The first center hole and the second center hole are arranged such that centers thereof are overlapped. The through hole is configured to be larger than the fastening member receiving portion in a swinging direction with the first and second center holes serving as the center of swing.
