An attachment structure includes: a shaft part via which a plate-like member is supported on a body in a manner capable of being opened and closed; a torsion spring to be fitted on the shaft part exposed in an open state, the torsion spring generating a damping force when the plate-like member is brought to the open state; a temporarily fixing groove extending along the shaft part and into which a one-end portion of the torsion spring fitted on the shaft part is inserted to temporarily fix the torsion spring to the body; and a bracket that is fixed to the body in the open state and presses the one-end portion of the torsion spring. The plate-like member has a gap in which, in a closed state, the torsion spring can be moved along the shaft part so that another-end portion of the torsion spring is inserted into an insertion hole in the plate-like member.

An image forming apparatus includes a main casing, a cartridge, and a controller. The cartridge is attachable to the main casing. The cartridge includes a cartridge memory configured to store identification information. The controller is configured to perform a rewriting process to rewrite the identification information to information indicating that the cartridge is the normal cartridge, in a case where the controller receives a cancellation instruction to instruct to cancel the service contract and the identification information, which is stored in a cartridge memory of the cartridge attached to the main casing, indicates that the cartridge is the contract cartridge.

A logic circuitry package for a replaceable print apparatus component includes an interface including a power terminal and at least one logic circuit. The at least one logic circuit is configured to respond to communications sent to a first address via the interface and respond to communications sent to a second address via the interface. The at least one logic circuit is configured to in response to a first command sent to the first address, draw a first current on the power terminal; and in response to a hibernate command sent to the first address, respond to communications sent to the second address and draw a second current on the power terminal less than the first current.

A light emitting device includes a light emitting unit in which a resin housing extending in one direction holds a light emitting element emitting light in a light emitting direction intersecting the one direction, a suppressing member that extends in the one direction and suppresses deformation of the housing caused by heat, the suppressing member having a linear expansion coefficient different from a linear expansion coefficient of the housing, and a fixing portion that fixes the housing and the suppressing member to each other at a position overlapping, in the light emitting direction, a neutral axis of the housing or the light emitting unit or a neutral axis of the suppressing member in the light emitting direction, at plural places separated away from each other in the one direction or in a state of extending in the one direction.

A monitoring device is configured to monitor image recordation by a recorder using a recording material supplied from a first cartridge and a second cartridge. the monitoring device includes a memory and a controller. The controller is configured to obtain number-of-sheet information indicating a number of sheets on which the image recordation has been performed, first consumption amount information indicating a consumption amount of a recording material consumed from the first cartridge, and second consumption amount information indicating a consumption amount of a recording material consumed from the second cartridge, determine ratio information indicating a ratio of the recording material consumed from the second cartridge to a total consumption amount of the recording material consumed from the first and second cartridges based on the obtained first and second consumption amount information, and store the obtained number-of-sheet information and the determined ratio information in the memory.

Systems and techniques for depositing organic material on a substrate are provided, in which one or more shield gas flows prevents contamination of the substrate by the chamber ambient. Thus, multiple layers of the same or different materials may be deposited in a single deposition chamber, without the need for movement between different deposition chambers, and with reduced chance of cross-contamination between layers.

Methods are described allowing a vector signaling code to encode multi-level data without the significant alphabet size increase known to cause symbol dynamic range compression and thus increased noise susceptibility. By intentionally restricting the number of codewords used, good pin efficiency may be maintained along with improved system signal-to-noise ratio.
