Title: Travel path recognition device
Inventor: TAKAHASHI ARATA
IPC: G06T7/00
Filed: 1998-07-16
Abstract: PROBLEM TO BE SOLVED: To reduce an erroneous recognition rate in a travel path recognition method. SOLUTION: Road picture taken in from an on-vehicle camera is divided into plural windows. Plural introduction candidates are extracted from the respective windows by a picture processing and they are used as divided candidate line data. Relevancy between data is obtained by using an extension Kalman filter and divided candidate line data in the respective windows are combined based on relevancy (S160). A candidate line with which the whole constitution number of combined candidate line data becomes the largest is recognized to be a true introduction line (S170). Since constitution elements are gathered based on relevancy between data and they are synthetically judged, the influence of noise is less. Thus, the erroneous recognition rate can be reduced.

Title: Manufacture of aldehyde
Inventor: HERUMUUTO BAARUMAN
IPC: C07C45/50
Filed: 1986-09-19
Abstract: The present invention relates to a process for the preparation of aldehydes by the reaction of olefinic compounds with hydrogen and carbon monoxide in the presence of a catalyst system containing rhodium and aromatic phosphines. The aromatic phosphines are soluble in organic media and represent salts of sulfonated or carboxylated triarylphosphines which are insoluble in water. After hydroformylation, the reaction product is treated with a diluted aqueous solution of a base and the aqueous phase containing rhodium and aromatic phosphines is separated. Thus, thermal loading of the catalyst, for example by the redistillation of the reaction product, is avoided.

Abstract: PURPOSE:To cut the number of transmission lines down to just one by transmitting the modulated time information based on a reference clock having the time width of the minimum unit for display of time. CONSTITUTION:A clock circuit 33 of a time device 25 produces the time information 32 which counts up the time based on a reference clock 30. When a time setting switch 35 is pushed, a time setting signal 53 is supplied to a control circuit 40. The circuit 40 receives the supply of a one-second signal 54 from the circuit 33. Then a shift signal 56 having a frequency 1/2 as high as that of the clock 30 is sent to a shift register 39 synchronously with the clock 30. A data train of 'year', 'month', 'hour', 'minute' and 'second' of the information 32 is moved with a shift action of the register 39 and supplied to a CMI coding circuit 41 in the form of the shift-out data 57. As a result, the data 57 undergoes the CMI coding and is converted into a transfer signal 36. This signal 36 is sent to an information processor 26.
