Inventor: TSUCHIYA TATSUMI
IPC: C07H19/073
Filed: 1986-08-27
Abstract: PURPOSE:To obtain a fluorodeoxyuridin useful as an anticancer agent, etc., in good yield, by distilling a solvent off without decomposition of an intermediate by addition of a Ca compound into a reaction mixture prepared by reacting deoxyuridine with a fluorinating agent in a fatty acid solvent. CONSTITUTION:First, a 2'-deoxyuridine compound expressed by the formula [R<1> represents -C(=)R<2> (R<2> represents 1-10C aliphatic groups)] is reaction with an electrophilic fluorinating agent (example; F2, etc.) in a 2-4C fatty acid solvent (preferably acetic acid). Then into the reaction mixture containing an intermediate formed by the reaction, is added a calcium compound (preferably calcium carbonate) normally in 1-10mol ratio based on 1mol raw material expressed by the formula and the solvent therein is distilled off. The intermediate obtained after the distillation of the solvent is preferably transformed into 5'-fluoro-2'-deoxyuridine by a known method.

Title: Evaporated fuel processing method for lean burn internal combustion engine and device thereof
Inventor: TAKAGI NAOYA
IPC: F02F3/26
Filed: 1998-07-15
Abstract: PROBLEM TO BE SOLVED: To unevenly distribute evaporated fuel at an arbitrary location within a combustion chamber and to purge the fuel without disordering the state of air-fuel mixture by generating spiral of supplied air from a suction passage to the combustion chamber, feeding evaporated fuel led to the suction passage on the spiral flow into the combustion chamber. SOLUTION: Atmosphere and evaporated fuel introduced into a helical port 7b flow into a combustion chamber 5 together with new air flowing from the upstream of the helical port 7b. At the time, because opening of a swirl control valve is small, most of new air sucked into the combustion chamber 5 flows from the helical port 7b and strong swirl flow is generated. Further, because a distance between a purge port 70a and the combustion chamber 5 is short, evaporated fuel does not mix with new air and forms unevenly distributed gas which is unevenly distributed within the combustion chamber 5. As a result, evaporated fuel is unevenly distributed at an arbitrary location within the combustion chamber 5, purging the fuel without disordering the state of air-fuel mixture to prevent deterioration of the combustion state.

Title: Scanning system
Inventor: NAKANO HIROYUKI
IPC: G01R31/28
Filed: 1983-10-26
Abstract: PURPOSE:To prevent an FF in a logical block from being broken owing to scanning by composing a shift register of plural series-connected FFs and connecting the 1st FF to a scan-out terminal and the final FF to a scan-in terminal. CONSTITUTION:When N bits are scanned out, a start address is set in a register 8 and N is set in a down counter 10. The data is scanned out of the logical block 1 with a shift signal and an up counter 9 counts up by one at the same time. The FFs in the logical block 1 are connected annularly, so the scan-out data becomes scan-in data as it is and is not destroyed. When the values of the counters 9 and 8 become coincident with each other, a comparing circuit 11 turns on the signal S3 of a gate circuit 12 and an AND circuit 7-2 turns on to store the scan-out data in the shift register 5 while the down counter 10 counts down by one. Thus, the counter 10 goes down to zero according to decrement and then the signal S3 is turned off to turn off the AND circuit 7-2, storing the scan-out data in the shift register 5.

Title: Abnormality detecting method for exhaust gas reflux system for engine
Inventor: SOGAWA TAKAYUKI
IPC: F02M25/07
Filed: 1991-08-09
Abstract: PURPOSE:To prevent the occurrence of erroneous diagnosis by accurately detecting abnormality of an exhaust gas reflux system, being in a state that reflux of exhaust gas is executed, without being influenced by an open air temperature. CONSTITUTION:When, after an output change DELTATS of an output voltage TSEGR 0 of an EGR temperature sensor during establishment of a diagnosis condition and a present output voltage TSEGR of an EGR temperature sensor is calculated at S216, a state that the output change DELTATS is lower than a set value is continued for a given time, it is decided from close stick of an EGR valve that a trouble where exhaust gas does not reversely flow to a suction system occurs. Namely, only when, after establishment of a diagnosis condition, the temperature of an EGR passage is below a set temperature and besides a slight temperature change is produced even when a given time elapses, it is decided that a close stick trouble occurs. Thereby, even when an open air temperature is low and an exhaust gas reflux gas temperature detected by the EGR temperature sensor is lower than an actual temperature, accurate decision of a trouble is practicable and erroneous decision can be prevented from occurring.

Filed: 1998-07-15
Abstract: PROBLEM TO BE SOLVED: To provide a laser heat transfer recording material which prevents the break of a light/heat conversion layer itself by laser beam from occurring and also prevents the printing sensitivity from being deteriorated and further shows the high clarity of a recorded image and rapid image recording. SOLUTION: The laser heat transfer recording material has at least a light/ heat conversion layer composed mainly of a near infrared ray absorbing material and a binder resin and a heat transfer ink layer laminated in that order, on a base. The binder resin to be used is a crosslinked resin composition and therefore the high sensitivity heat transfer recording material is obtained which shows high heat resistance in the light/heat conversion layer and is not softened even at the time of high laser beam output. In addition, appropriate foil retaining properties and high heat resistance are obtained by using carbon black which is an inorganic particle material as the near infrared ray absorbing material.

Filed: 1988-08-11
Abstract: PURPOSE:To improve formability and to secure a high water-tightness of a sealing part by using a polymer alloy of a polyphenylenether and a nylon as an insulating packing.

Title: Input part monitoring method
Inventor: NISHIMURA TATSUFUMI
IPC: G01R31/00
Filed: 1992-07-07
Abstract: PURPOSE:To change a faulty detection sensitivity regardless of an input signal level and to monitor an input part reliably by comparing a value which is obtained by multiplying the scalar sum of a three-phase AC signal by a constant coefficient with the minimum faulty detection sensitivity which is previously set. CONSTITUTION:For example, when an absolute value error and a phase error are included in an input part 1b, the level of the error constituent generated by the absolute value error is proportional to the scale of a voltage vector for phases A, B, and C. Then, the vector sum of A-C phase voltage vectors Va, Vb, and Vc read from a power system to input parts 1a-1c is obtained and the error constituent generated by the input part 1b is calculated. Then, a scalar sum VR of A-C phase voltage vectors is obtained, a value which is obtained by multiplying it by a specific coefficient is compared with a faulty detection sensitivity epsilon0 which is previously set, and then the larger one is determined as the faulty detection sensitivity epsilon. In this manner, since the faulty detection sensitivity epsilon is determined according to the input signal level, the monitoring accuracy for input parts 1a-1c can be retained constantly even if the input signal level changes.
