摘要:
It is provided about a communication system adapting for car, communication apparatus adapting for car and a communication method adapting for car that can perform data transmission under extensive range from a low speed communication to high speed communication, without generating data delay, data dropout and the like, caused by the data sending collision.A gateway and an ECU are connected to each other, in a one-to-one manner, via a communication line different from another communication line for another connection. When receiving a message, the gateway and the ECU reply a receipt response. When having a message to be sent toward the destination for replying at this replying time, the gateway and the ECU sends the receipt response onto which this message to be sent is added. When a message sending collision is generated, the gateway preferentially performs a message re-sending operation.

A packaging box includes a box body having a bottom board, side boards, and bending flaps; and a cushioning material having a bottom surface section and side surface sections. A restrainer is formed at least one of the bending flaps, the restrainer having a portion that is separated from and opposes the bottom board when the portion of the restrainer is bent into an accommodation space of the box body. A restrain portion is formed at the side surface section of the cushioning material opposing the restrainer formed at the at least one of the bending flaps, the restrain portion having a portion that is positioned at a side of the bottom board so as to abut upon the portion of the restrainer and that opposes the portion of the restrainer when the cushioning material is fitted in the accommodation space of the box body.

A projection image display apparatus includes: a light source; an illumination optical system that uniformly irradiates a surface of an image modulation element serving as a primary image surface with a light beam emitted from the light source; and a projection optical system that enlarges and projects image information on the primary image surface modulated by the image modulation element onto a screen serving as a secondary image surface, and that includes a first optical system that forms an intermediate image from the image information, a single-image second optical system that enlarges and projects the intermediate image to display a single image on the screen, a plural-image second optical system that enlarges and projects the intermediate image to display plural images on the screen, and an optical path switching mechanism that selectively guides a light beam from the first optical system to the single-image or plural-image second optical system.
摘要:
An image recording apparatus including: (a) a first conveyor configured to convey a recording medium along a first conveyance path; (b) a first recording head; (c) a second conveyor configured to convey the recording medium along a second conveyance path; (d) a second recording head; (e) a third conveyor configured to convey the recording medium along a third conveyance path; and (f) a posture changer configured to change a posture of at least a downstream-side portion of the first conveyor between a first angular posture and a second angular posture, such that at least a downstream-side part of the first conveyance path is directed to the second conveyance path when the at least the downstream-side portion of the first conveyor takes the first angular posture, and such that the at least the downstream-side part of the first conveyance path is directed to the third conveyance path when the at least the downstream-side portion of the first conveyor takes the second angular posture.
摘要:
A projection type video display apparatus includes a projection lamp and a video signal processing circuit which performs video processing to an input video signal. The projection type video display apparatus includes means for performing an initializing process of the video signal processing circuit in a period until brightness of the projection lamp reaches brightness enough to project video since the projection lamp is lit and in a period except for a period during which lamp lighting noise is generated immediately after the projection lamp is lit.
摘要:
A cleaning roller is arranged at a position facing an image sensor with a conveying belt interposed therebetween. The conveying belt has a through hole. In an image sensor cleaning mode, the cleaning roller is inserted through the through hole and contacts the image sensor, while the image sensor is held without moving.
摘要:
An image processing apparatus is provided with an image reading unit configured to read an image on an original, the original being discharged from a discharging side of the image reading unit, an image forming unit configured to form an image on an recording medium, and a discharge guide configured to guide the original to the discharging side of the image reading unit, the discharge guide being arranged to cover the image forming unit from the discharging side of the image reading unit. The discharging guide is configured to be movable between an opened position and closed position with respect to the image forming unit, the image forming unit being exposed to outside when the discharging guide is located at the opened position.
