Abstract: An image forming apparatus includes an image forming unit, a controller including a master unit and a slave unit, and a serial communication line connecting the master unit and the slave unit and used in serial communication. The master unit includes an arithmetic module that generates first serial data to be transmitted to the slave unit to monitor serial communication, and monitors whether the first serial data has been successfully received in accordance with second serial data received from the slave unit. The slave unit includes a pulse signal output module that outputs pulse signals for a number of pulses which is set from the first serial data, an analog voltage output module that receives the pulse signals, changes an analog voltage in accordance with the number of pulses, and outputs the analog voltage, and an analog/digital conversion module that converts the analog voltage into the second serial data.

Abstract: A liquid ejection head driving system includes an ink jet head, a driving circuit substrate provided with a driving circuit in which a driving signal is generated, a driving signal wiring that branches an output of the driving circuit into two or more systems, and a plurality of connectors that extract the driving signal wiring for each system, and a flexible flat substrate (FFC) in which a connector connected to a connector of the driving circuit substrate is installed, a driving signal pattern for transmitting the driving signal for each system is formed on a first layer, and a reference potential pattern is formed on a second layer. The driving circuit substrate is configured such that the same number of connectors as the number of wiring substrates are mounted at a position where a direction of insertion and extraction of the connector of the FFC is released.

Abstract: A combined holder for displaying and packaging a decorative midget lamp assembly, which can be satisfied with beauty of concentrative random twinkling and flickering of the plurality of light sources displacing toward left and right generating from on-off controlling operation of the light sources, the holder can effectively use a cover portion formed in the package condition where the portion of the power cable occupying approximately 80% of space in the overall decorative midget lamp assembly is hidden, as a space for displaying a fantastic picture, and the holder can also ornament it on a tree or other structures after taking out it from the holder as usual.

Abstract: An arrangement for a lure which stabilizes the movement of a fishhook attached to the fishhook attaching section formed on the lower side of the lure in order to positively catch fish with the fishhook. A two movement guide sections are provided by cutout portions formed inside of external members of a lure body. Spherical metallic weight is movably accommodated in each of the movement guide sections so that the spherical metallic weights can be moved in the longitudinal direction of the lure body. When the weights in the movement guide sections are moved to the front, a center of balance of the weights substantially coincides with the position of a fishhook attaching section.
