Filed: 1992-06-25
Abstract: PURPOSE:To obtain a new compound, useful as a synthetic raw material for sphingoglycolipids and producible in good yield from a readily available and inexpensive raw material. CONSTITUTION:The compound of formula I (R<1> is 15-25C alkyl or alkenyl; R<2> is 10-20C alkyl or alkenyl), e.g. a compound of formula II. This compound is obtained by reacting a phosphonic acid ester of formula III (R is methyl, ethyl, etc.) with a long-chain aldehyde (e.g. tetradecylaldehyde) in the presence of cesium carbonate or potassium carbonate in isopropyl alcohol preferably at -20 to +30 deg.C, providing a new intermediate of formula IV and then reducing the resultant intermediate with sodium boron hydride or zinc boron hydride in the coexistence of cerium chloride. Furthermore, the compound of formula III is obtained by carrying out, e.g. both the N-acylation and the introduction of N,O-isopropylidene group into a serine ester and then reacting the resultant N-long-chain acyl-N,O-isopropylidene seine ester with methylphosphonic acid diester.

Filed: 1989-07-24
Abstract: PURPOSE:To eliminate the need for the provision of a reception electric field detecting means on a reception end, to minimize the circuit scale at the reception end and to realize the transmission power control by inserting the information of transmission error of a line detected at the reception end of a 1st line in the digital microwave communication system to an idle time slot of a 2nd line whose direction is opposite to the 1st line, transferring the result to the transmission end of the 1st line and using the information to control the transmission power of the transmission end. CONSTITUTION:Suppose that a reception electric field received by a receiver 6 is much decreased, an error takes place in an output data of the receiver. The error is detected by a detection circuit 7 and the result is fed to a memory 8. Error information in the memory 8 is inserted to an idle time slot of the data of an opposite line, sent from a transmitter 9 and received by a receiver 2. The error information inserted to the idle time slot of the data is inputted to a control circuit 3. The control circuit 3 always monitors error bit information inputted from the receiver 2 to control the transmission power by the method of perturbation. Thus, the transmission power of a transmitter 1 is controlled.

Title: Attachment for crosshead-type extruder
Inventor: NAGAI NAOAKI
IPC: B29C48/09
Filed: 1982-11-01
Abstract: PURPOSE:To obtain the titled attachment wherein a rubber hardly stagnates, by a method wherein a stagnant flow of a rubber at an outside wall part of a passage at a confluent point is deflected by a specified quide part. CONSTITUTION:Circumferential rubber flows divided to the left and the right in an annular passage 2 are mixed into complicated rubber flows in the attachment A, and the mixed flow is deflected to be an axial flow along a supplying hole 3.
