In the print position adjustment procedure when performing bidirectional printing by using a first head and a second head, patterns (A) and (B) are printed to adjust the print positions of the first and second heads relative to each other in each of the forward and backward directions. A pattern (C) is printed to adjust the print position deviation of one of the two heads (first head) between the forward and backward directions. From these patterns three correction values are obtained to perform corrections. This allows the print position alignment between the forward and backward scans for one head (first head) to be performed by using the pattern (C). The print position alignment of the second head with respect to the first head as a reference in each of the forward and backward directions can be performed by using the patterns (A) and (B). As a result, print position deviations that may occur when the printing apparatus performs bidirectional printing using a plurality of heads can be minimized without having to maintain the precision of the apparatus at so high a level.

The electric power breaker for breaking the electric power is placed on the midpoint of the electric power line from the battery power supply, and the electric power line is extracted from the electric power breaker. In addition, the electric power supply terminal is placed on the midpoint on the electric power line, from which the electric power is supplied to the individual electric load. The electric power distribution and the electric power supply operation to the electric loads are controlled by the multiplex communication. A semiconductor device having a self protection function is used as the switching device for supplying the electric power. The electric power line covered by the electric conductive material is arranged in a loop topology so as to start from the connection point to the battery and pass through the designated positions in the vehicle and return to the battery. On the designated points on this loop, plural control modules are connected, and the electric power is supplied to them from the battery. By isolating plural electric conductive parts of the electric conductive layer covering the electric power line, each part connected to the abnormality detection circuit of the individual control module, and by detecting the electric potential change in the individual electric conductive part, the position of the abnormality can be identified by the position of the isolated electric conductive part where the short circuit abnormality is detected.

An image transfer apparatus that records an image through selective heat and pressure application has an ink ribbon and a film disposed between a driving head and a flat platen. Color dyes of the ink ribbon are transferred to the film as the image. The image on the film is thus conveyed to a position for transferring the image to a recording sheet. The film and the recording sheet are pressed between a transfer roller and a conveyer roller with a pressure that sufficiently smoothes unevenness in the surface of the recording sheet. A high quality image is thus recorded on the recording sheet regardless of the surface condition of the recording sheet.

An image-forming liquid medium comprised of a solution containing a surface-active agent, and at least two types of microcapsule mixed with the solution. A first type of microcapsule is filled with a first dye, and a second type of microcapsule is filled with a second dye. A first shell of the first type microcapsule is formed of a first resin that exhibits a first characteristic such that, when the first type microcapsule is squashed and broken under simultaneous application of a first pressure at a first temperature, the first dye seeps from the squashed and broken microcapsule. A second shell of the second type of microcapsule is formed of a second resin that exhibits a second characteristic such that, when the second type microcapsule is squashed and broken under simultaneous application of a second pressure at a second temperature, the second dye seeps from the squashed and broken microcapsule.

A power supply line is wired in a loop from a battery power supply, and a power supply relay circuit is installed intermediately of the power supply line such that power is supplied from the power supply relay circuit to an electric load connected to a terminal unit of an intensive wiring line. By this arrangement, not only wires for control signals but also wires for power supply can be reduced. The terminal unit may serve also as the power supply relay circuit.

A camera has a back cover movable between a closed state and an open state to enable a film case to be installed in and removed from the camera. A detector detects the transition of the cover between the closed state and the open state. A data register stores control data, and a control circuit receives the control data from the data register for controlling operation of the camera. The control data is transferred temporarily from the data register to an EEPROM when the back cover makes the transition from the closed state to the open state. The control data is then transferred back from the EEPROM to the data register when the back cover makes the transition from the open state to the closed state. By temporarily storing the control data in an EEPROM when the back cover is open, and transferring the control data from the EEPROM back to the data register when the back cover is closed, the adverse effects of static electricity, external noise or resetting of the control circuit are prevented from disrupting the operation of the camera.

A microcapsule includes a shape memory resin shell wall formed with fissures that do not completely pass through the shell wall, and a dye encapsulated in the shell wall. The shell wall exhibits a temperature/pressure characteristic such that the fissures open, when the shell wall is squashed and compacted under a predetermined pressure at a predetermined temperature, whereby a seepage of the dye frog the squashed and compacted shell wall through the opened fissures is adjustable.

摘要:
A printer includes a tractor unit for feeding continuous form paper, encoders driven in synchronization with the tractor unit, and detecting sensors for detecting the encoders to generate feed pulses at a standard interval. The printer further includes a paper top sensor for detecting a leading edge of the continuous form paper to generate paper top signal and is arranged to control the feed of the paper based on the feed pulse generated after the paper top signal. In order to adjust the printing position on the paper in case where the scanning position is misaligned due to a manufacturing error, the position of the detecting sensors is adjustable with respect to the encoders to compensate for the error. Further, the position of the paper top sensor is adjustable with respect to the tractor unit in order to keep the relationship between the feed pulse and the paper top signal unchanged regardless of the adjustment of the detecting sensors.
