Title: Production of vitamin a or carboxylic acid ester thereof
Inventor: ODERA JUNZO
IPC: C07C403/08
Filed: 1985-10-16
Abstract: PURPOSE:To readily obtain a compound useful as a medicine, feed additive, etc., from a readily available and inexpensive raw material in good yield, by treating a vinyl sulfone with a base, and, as necessary, acylating the resultant vitamin A. CONSTITUTION:A novel vinyl sulfone expressed by formula I (R<1> is optionally substituted phenyl; R<2> represents H or lower acyl) is reacted with a base (example; potassium methoxide) in an organic solvent such as hexane at 10-120 deg.C to obtain vitamin A. Then, as necessary, the product is reacted with an acylating agent (example; acetic anhydride) in an organic solvent in the presence of a tertiary amine to obtain a vitamin A carboxylic acid ester. The reaction is carried out by using 2-20mol, based on 1mol vinyl sulfone expressed by formula I, base and 1-10 equivalents, based on the vitamin A, acylating agent. The compound expressed by formula I can be obtained by reacting a hydroxysulfone expressed by formula II with a halogenating agent, hydrolyzing, as necessary, and treating thus obtained halosulfone expressed by formula III with a dehydrohalogenating agent.

IPC: F23K5/08
Filed: 1988-09-16
Abstract: PURPOSE:To make it possible to exhibit the combustion performance of cracked heavy oil with inferior combustibility that is as good as that of C heavy oil by forming an atomization medium with a premix gas which consists of combustion gas and air or combustion exhaust gas. CONSTITUTION:After a city gas 13A based on natural gas is boosted up to a specified pressure by a gas compressor 14, it is sent to a mixer 28. On the other hand the pressure of compressed air is regulated to a specified pressure by a pressure reducing valve 24 and then sent to the mixer 28. The 13-60% of the fuel gas 13A which is led to the mixer 28 and the compressed air are mixed under the same pressure, and after they are straightened in flow in a mixing tank 30 they are sent to a burner. And, when combustion by atomization under gas pressure is applied to a heavy oil such as cracked heavy oil which is inferior in combustibility, if this premix gas is used as the atomization medium for atomizing heavy oil, it is possible to make large the ratio of gas mass flow rate to liquid mass flow rate and to provide uniform atomization of the fuel oil without increasing the quantity of the combustion gas.

Title: Transfer loop preventing system in multistage transfer service
Inventor: KATO YUMIKO
IPC: H04M3/54
Filed: 1988-09-19
Abstract: PURPOSE:To effectively use the resource of the whole network by comparing incoming call identifying information with the incoming call identifying information transmitted accompanying a new incoming call, and transmitting the new incoming call to a transfer destination subscriber at the time of inconsistency, and disconnecting the new incoming call at the time of consistency. CONSTITUTION:For example, when the call is returned through another station 11, etc., as a new incoming call to a transfer service execution subscriber 4, an incoming call comparing means 14 compares incoming call identifying information 13 of the incoming call 12 with incoming call identifying information 7 corresponding to the transfer service execution subscriber 4. When the both are consistent, the incoming call 12 is disconnected so as not to transfer the new incoming call 12 to a transfer destination subscriber 9 again. On the other hand, when the both are inconsistent, since it is a first arriving call at a station 5, the incoming call is transferred to the transfer destination subscriber 9. Thus, the resource (call processing resource) of the whole network can be effectively utilized.
