摘要:
A liquid crystal display cell being capable of display with liquid crystal molecules aligned towards a predetermined direction has its display characteristics made greatly dependent on the properties of an alignment film coming into contact with the molecules of the liquid crystal. A louver having a predetermined angle is disposed between the substrate on which the alignment film is to be formed and an evaporation material source to pass a material evaporated from the evaporation material for deposition onto the substrate. The thus formed film exhibits a very great orientation controlling power of biaxial anisotropy. This forming method of the alignment film also allows the easy formation of the alignment film on a large substrate.

In a liquid crystal display (LCD) device having a thin film transistor (TFT), the TFT includes a source electrode, a drain electrode and a semiconductor layer. At least one of the source electrode and drain electrode includes a first layer including copper and a second layer forming an oxide layer and covering the first layer. The semiconductor layer has a substantially linear current-voltage relationship with said source electrode or drain electrode including said first and second layers, when a voltage is applied between the semiconductor layer and said source electrode or drain electrode.

A recording apparatus comprises a first gear, a second gear meshable with the first gear, a third gear meshable with the first gear and the second gear. The third gear has a peripheral surface on which a toothed portion meshable with the first gear and an untoothed portion not meshable with a toothed portion of the first gear are disposed opposable to the first gear, and a peripheral surface on which a toothed portion meshable with the second gear is disposed opposable to said second gear, a gear drive switching control unit controls switching such that when the toothed portion adjacent the untoothed portion of the third gear comes into contact with the first gear, the second gear and the third gear are meshed to rotate the third gear to oppose the untoothed portion of the third gear to the first gear, thereby releasing the contact between the first gear and the third gear.

A recovery device is described for use with a recording head of an ink jet recording apparatus. The recording head is mounted on a carriage which can reciprocate. The recovery device includes a cap for capping an ink discharge portion of the recording head when not in use, and a wiper for wiping out the ink discharge portion with a movement of the carriage. The wiper is disposed outside the cap relative to the recording area. The recording head does not pass through an area occupied by the wiper when the recording head performs a predischarge with respect to the cap during recording.

A replaceable tank for an ink cartridge used in a bubble jet printer comprises a container formed by side walls, top and bottom walls connected to the side walls. At least one ink supply port is provided in the bottom wall of the container and is disposed for supplying ink from at least one ink chamber in the container into a corresponding ink tapping pipe in the ink cartridge. The container includes a locking member on one of the container side walls for engaging a guide groove in the cartridge, the container being configured for insertion into an open top of an ink tank holder formed by the cartridge, with the bottom wall of the container facing downward and the side walls of the container aligned with side walls of the ink cartridge. The locking member is constructed for securing the container in place in the ink tank holder with the ink supply port connecting with the corresponding ink tapping pipe.
