Inventor: KUME TAKEO
IPC: F02D45/00
Filed: 1986-03-29
Abstract: PURPOSE:To detect a misfiring cylinder reliability by detecting a misfiring information in the downstream of an exhaust manifold collecting section then stopping fuel supply sequentially if the misfiring is occurring and deciding that the misfiring is occurring in the cylinder from which a misfiring information is not detected. CONSTITUTION:In the misfiring decision method of specific cylinder in a multi- cylinder engine 2, a misfiring information (output from an exhaust gas temperature sensor 56 or an O2 sensor 46) is first detected in the downstream of an exhaust manifold collecting section, and if the occurrence of misfiring is detected (the exhaust gas temperature 56 is higher than a predetermined level and the O2 sensor 46 exhibits leaner level than a predetermined one), it is decided that any one cylinder is misfired. Consequently, fuel supply to a fuel injection valve 6 is stopped sequentially and when a misfiring information is not detected in the downstream of an exhaust manifold collecting section, it is decided that misfire is occurring in a cylinder to which the fuel supply is stopped. Consequently, the misfiring cylinder can be detected reliably.

Title: Data determining/transmitting method and device
Inventor: JIEREMII JII DAN
IPC: G01C3/06
Filed: 1996-02-21
Abstract: PROBLEM TO BE SOLVED: To provide a measuring device which does not use a ratio frequency that requires permission. SOLUTION: A device concerned 10 includes a laser measuring device 12 to decide the position data of a selected target. This laser measuring device 12 generates pulses which are transmitted to the target and reflected thereby, decides the range for the target in accordance with the transmission and reflection of optical pulses, and determines the horizontal and vertical angles of the device to the target. These values of range and angles constitute the position data. The position data is modulated with optical pulses so as to form an optical signal to be transmitted to a remote place.  When the selected target is positioned remotely, an optical signal for transmission of the position data is formed by using the same optical pulses as used in determination of the position data, when the optical pulses can be utilized at the same time in determination of the position data and the data transmission to the target.

Title: Area attribute identifying device
Inventor: IKEMURE YUMIKO
IPC: G06F17/21
Filed: 1991-04-08
Abstract: PURPOSE:To execute the division and identification of an area based on binary data fetched from a scanner and to judge a character typesetting direction while using an inter-character/inter-line feature when the identified area is a character area. CONSTITUTION:In respect to the area divided by an area division part 11 and judged as the character area by an area judgement part 12, a histogram minimal value detection part 13 calculates respective horizontal and vertical histograms and detects a position where the respective histograms are turned to be minimal. An inter-character/inter-line detection part 14 calculates a distance between the minimal values. Since the distance between the minimal values calculated at this part 14 can be defined as character size + line space or character size + character space, the inter-character/inter-line detection part 14 detects the character space/line space. According to the feature that the line space is larger than the character space, a character type setting judgement part 15 decides the direction of the large distance between the minimal values as the character typesetting direction. Thus, since the typesetting of the character is judged by using the feature of the character space/line space, the typesetting of the character can be judged without being affected by the shape of the character.
