Patent number: 7499056Abstract: In forward scanning, a timing control unit outputs the display data in the same sequence as the input display data. In backward scanning, on the other hand, the timing control unit inverts the output sequence of the display data for one line (for one horizontal cycle). Upon input of a scan direction control signal indicating backward scanning, the timing control unit executes sequence change processing by using line memory. The display data in which the sequence of the pixel data is reversed is outputted together with the control signals. It is able to select whether to output data in an inverted sequence or in a normal sequence according to the scan direction control signal.Type: GrantFiled: June 4, 2004Date of Patent: March 3, 2009Assignee: Mitsubishi Denki Kabushiki KaishaInventors: Takayuki Fukuda, Hirofumi Iwanaga, Jiro Takaki

Patent number: 7099730Abstract: A terminal table unit is associated with an output apparatus such as valves and solenoids and an input apparatus such as switches and includes not only a main body with a control device and a memory device but also a cassette with a memory medium that is detachably attached to the main body. The control device receives input data from the input apparatus for controlling the output apparatus and drives the output apparatus according to the received input data. The received input data are temporarily stored in the memory device in specified units. When the input data are found to include abnormal data, the control device causes data stored in the memory device to be transferred to the memory medium of the cassette such that the memory cassette can be removed and the abnormal data stored on the memory medium can be analyzed elsewhere.Type: GrantFiled: March 12, 2004Date of Patent: August 29, 2006Assignee: OMRON CorporationInventors: Masanori Yamashita, Hiroshi Hashimoto, Masaru Imoto, Hajime Izutani, Fumihiko Okumura, Tomoaki Yoshikawa, Hirofumi Iwanaga
