A looseness detection structure includes: a structure (transducer) T which is formed on a surface of a cable; a screw which tightens and fixes the cable in contact with the structure T; and a terminal (detection unit) which transmits a transmission signal to the structure T, receives a reception signal returning after propagating through the structure T, and detects the loosening of the screw based on a change in the reception signal.

Loosening detection structure and loosening detection method using said structure

A printing apparatus accepts a start instruction of a printing operation and controls, in a case where the instruction is accepted during execution of a maintenance operation and a specific condition is satisfied, to interrupt the maintenance operation and start the printing operation. The specific condition includes that an accumulated time from a start of the maintenance operation to an interruption of the maintenance operation is shorter than a threshold value. In a case where the instruction is accepted during execution of the maintenance operation and the specific condition is not satisfied, the printing operation is started after the maintenance operation is complete.

Printing apparatus and control method thereof

A corrosion rate estimation apparatus includes a corrosion rate measurement unit adapted to repeat water supply cycles in which water is supplied to soil in which metal to be evaluated is buried and measure a cycle number of each water supply cycle, one or more time points in each cycle, and a corrosion rate of the metal at the time point(s); a learning unit adapted to find a prediction model by accepting the cycle number, the time point(s) in the cycle, and the corrosion rate(s) as input and using a machine learning algorithm, the prediction model representing a future corrosion rate; and a corrosion rate estimation unit adapted to assign a cycle number and a time point in the cycle at which a corrosion rate is desired to be estimated to the prediction model and estimate a corrosion rate of the metal at the time point.

Corrosion rate estimating device and method

An optical waveplate includes a polyimide with a film thickness of 20 .mu.m or less.

Optical waveplate and A method of manufacturing the optical waveplate

A sheet discharge apparatus for a printer comprising a platen, a first discharge roller unit movable toward and away from the platen and defining a first sheet insertion passage at a location between the platen and the first discharge roller unit, an openable and closable top cover, a second discharge roller unit mounted for longitudinal movement in parallel relation to the top cover, to define a second sheet insertion passage at a location between the first discharge roller unit and the second discharge roller unit, and positioning means for the second discharge roller unit, which is provided on the printer body.

Sheet discharge apparatus for printer

A platen assembly has a pipe shaft having an elastomeric layer therearound, an end of the pipe shaft having cutouts therein extending parallel to the axis thereof and having locking holes therein between the cutouts, and a power transmission member connected to the end of the pipe shaft, the power transmission member having first convexities removably engaged in the cutouts for holding the member against rotation relative to the pipe shaft, and second convexities resiliently removably engaged in the locking holes for holding the member against disengagement from the pipe shaft.

Platen assembly

A ribbon cartridge comprises a case, a sliding guide slidably mounted in the case, and an endless ink ribbon enclosed in the case. A greater part of the ribbon is enclosed in the case at a space between the sliding guide and an inlet side of the case. The sliding guide has a front guide plate at an inlet side thereof, and a rear guide plate at an outlet side. The front guide plate has a vertical inlet slit and the rear guide plate has an inclined outlet slit. The ink ribbon is engaged with both the slits so as to correct any twist thereof.

Ribbon cartridge for printers

An inked ribbon changeover mechanism for a printing machine, in which a plurality of inked ribbons are looped over a plurality of guide members, respectively. The guide members are carried on a movable member, which is arranged to be movable to first and second positions relative to a printing head such that a selected one of the inked ribbons is placed in an operative position in which a portion of the selected one of the inked ribbons is located in a space between the printing head and a record medium when the printing head is in a printing position.
