Title: Novel oxazole and its production
Inventor: KATSUURA AKIO
IPC: C07D263/34
Filed: 1999-06-28
Abstract: PROBLEM TO BE SOLVED: To provide a novel compound that is an oxazole bearing a specific substituent and is useful as a starting substance for a therapeutic agent for hepatitis C. SOLUTION: This novel compound is represented by formula I (R1 is an alkoxy or a halogen; R2 is H or an alkyl), typically 5-(2-methoxy-4-nitrophenyl)-4- carboethoxy-oxazole. The compound of formula I is prepared by allowing a benzoic acid of formula II (for example, 2-methoxy-4-nitrobenzoic acid), usually in its acid chloride, to react with an isocyanoacetic acid of the formula: CNCH2 COOR2 (ethyl isocyanoacetate), usually in its ester, in an organic solvent (for example, N,N-dimethylformamide or the like) in the presence of a base (for example, triethylamine or the like) at 0-50 deg.C for 2-4 hours.

Title: Speed checking system
Inventor: OKUYAMA MASASHI
IPC: G01P1/10
Filed: 1982-10-18
Abstract: PURPOSE:To check a speed with high precision, by forming a pulse corresponding to the period of an input pulse exceeding a set speed each time when the input pulse attained by movement detection is inputted and comparing the interval of time between two pulses with a set time. CONSTITUTION:An input pulse forming means 1 forms pulses whose period is changed in accordance with the movement speed of a moving object, and a minic high-speed pulse forming means 2 forms another pulse corresponding to the period of input pulses for movement in a speed higher than the set speed each time when the input pulse is inputted to the means 2. A processing device 4 measures an interval T of time between said two pulses inputted through an OR circuit 3 and compares the interval T with an internal set time T0 to output logical output ''1'' for T>T0 and output logical output ''0'' for T<=T0. When the speed of the moving object is lower than the set speed, the device 4 outputs ''0'' and ''1'' alternately; and when it is equal to or higher than the set speed, the device 4 outputs only ''0''. The presence or the absence of the AC output is detected by an AC output detecting means 12 in the next stage of the device 4; and when the AC output is detected, a detection output indicating that the speed of the moving object is lower than the set speed is outputted.
