Provided is an etching solution composition for selectively etching a metal film, which is composed of Al, Al alloy or the like and is arranged on an amorphous oxide film, from a laminated film including the metal film and an amorphous oxide film of various types. The etching solution composition is used for selectively etching the metal film from the laminated film which includes the amorphous oxide film and the metal film composed of Al, Al alloy, Cu, Cu alloy, Ag or Ag alloy, and is composed of an aqueous solution containing an alkali.

A method includes determining, if power to an apparatus is turned on, whether a state of a sheet has been changed while the power is off, based on a change of the sheet state before turn-off and after turn-on of the power, and performing control to perform initializing operations according to a result of the determination.

A semiconductor device has a high-speed circuit and a high-density circuit, each having at least two field effect transistors and two gate electrodes. In the high-speed circuit, a first gate electrode of a first field effect transistor and a second gate electrode of a second field effect transistor are separated by a first pitch. In the high-density circuit, a third gate electrode of a third field effect transistor and a fourth gate electrode of a fourth field effect transistor are separated by a second pitch. The first pitch is larger than the second pitch. Provision of a notch in the third gate electrode of the third field effect transistor in the high-density circuit, at a portion reached by a shared contact hole shared by the third gate electrode and the fourth transistor, increases the contact area between the shared contact hole and an impurity region source/drain of the fourth transistor.

An ink jet recording apparatus is equipped with an upstream side conveyance unit arranged on a conveyance upstream side of a recording head and a downstream side conveyance unit arranged on a conveyance downstream side thereof. The inkjet recording apparatus obtains, by recording a test pattern on a sheet, a conveyance correction amount when conveyance is performed solely by the downstream side conveyance unit. The inkjet recording apparatus includes a control unit which, when effecting an arbitrary recording, effects control such that, when a sheet trailing edge leaves the upstream side conveyance unit, a rotating position of a drive side roller of the downstream side conveyance unit is the same as the rotating position of the drive side roller when the test pattern is recorded.

A conveyance apparatus includes: a supply unit rotatably supporting a roll member around which a sheet is wound in form of a roll and configured to supply the sheet from the roll member; a motor for rotating the roll member; a roller pair configured to convey the sheet supplied from the supply unit while pinching the sheet; and a control unit configured to set the torque of the motor according to sheet information related to the sheet when taking up the sheet on the roll member by driving the motor while the sheet is pinched by the roller pair being stopped.
摘要:
This invention has been made to cause a printing apparatus for conveying roll paper and performing printing to simultaneously attain a stable conveyance accuracy and prevent skewed conveyance independently of LF roller driving conditions and disturbance conditions that variously change as the roll paper state changes. For this purpose, a feed motor is used as a load generator for the roll paper. A section from a conveyance operation by the LF roller to the next conveyance operation is divided into a plurality of sub-sections. A feed mechanism is controlled by switching between a feeder load generation section and a feeder load zero section for each sub-section.
