摘要:
The present invention provides a method for producing a 12-membered ring macrolide compound expected as a prophylactic or therapeutic agent for solid tumors and the like, and a production intermediate thereof. In detail, by acetalizing hydroxyl groups at 6- and 7-positions of a 12-membered ring macrolide compound being a raw material with dialkyl tin (IV) oxide and, after that, reacting the product with a carbamoyl halide derivative, the 7-position urethane derivative of the 12-membered ring macrolide compound being the target is effectively produced, without protecting hydroxyl groups at other positions.

The invention realizes a simple and easy file transfer system by setting a communication parameter without requiring a manual input by a user and transferring a parameter indicating a file transfer job.A third communication equipment transmits a communication parameter for executing a data communication between a first communication equipment and a second communication equipment, to the first communication equipment, and in response to the transmission of the communication parameter, receives a parameter indicating a file transfer job for transmitting files to the second communication from the first communication equipment, from the first communication equipment, and transmits the parameter indicating the file transfer job and the communication parameter to the second communication equipment.
摘要:
A wireless communication apparatus having first wireless settings includes a search unit which searches for a device which has second wireless settings corresponding to the first wireless settings, and a control unit which controls the wireless communication apparatus. If the device is found by the search unit and the device has not created an ad-hoc network, the wireless communication apparatus creates an ad-hoc network which includes the device. Further, if the device is found by the search unit and an ad-hoc network has been created by the device, the wireless communication apparatus joins the ad-hoc network which has been created by the device.

Namely, it provides a 12-membered ring macrolide compound represented by the following formula obtained from the incubation solution of Streptomyces sp. Mer. 11107 or a variant thereof, a pharmacologically acceptable salt thereof or a hydrate of them, and a process for producing it
摘要:
An armature for an electric rotating machine has a plurality of outer coil elements and a plurality of inner coil elements. Each of the coil elements has end protrusions extending axially outwardly from an axial side of an armature. The end protrusions facing each other in a radial direction is joined by an arc welding. In one method, the end protrusion of the outer coil element is formed a projection at an axially inside of an axial end of the protrusion. The end protrusions are held spaced apart from each other in the radial direction while contacting only through the projection. The axial ends of the protrusions are welded by swinging the welding arc. In another method, a ring-shaped brazing material is interposed between the end protrusions. The brazing material is melted by the welding arc to weld the end protrusions, while cutting out the brazing material existing between two adjacent pairs of the end protrusions.

A thermal printer of the type printing an image on a printing paper wound in the form of a roll. Curling of the printing paper wound in the roll form occurs when the thermal printer is placed in its standby mode over more than a predetermined period of time while the printing paper is held between a platen roller and a thermal head. In order to prevent curling of the printing paper, the printing paper is rewound when the standby mode lasts over more than the predetermined period of time.

摘要:
An image printing method and system. Information of printing paper size, image size to be printed and printing position is inputted by user. On the basis of the information, a control circuit determines the number of data to be printed in the primary scanning direction as well as the number of data for blanks at both sides and additionally determines the number of lines for printing in the secondary scanning direction as well as line numbers for processing and succeeding blanks. In the primary scanning, the data to be printed is supplied to a thermal head together with the data for the blanks. In the secondary scanning, a printing sheet is transported idly for the blank portions. The thermal head is electrically energized in the printing portion for printing the image at a predetermined position on the printing paper.

The semipermeable membrane contains a polyarylate resin and a polysulfone resin as a major membrane material and has a fibrilliform structure with a high mechanical strength and has a water permeability of 1,500 ml/m.sup.2.hr.mmHg or lower as well as an inhibitory rate against bovine serum albumin of 80% or higher and against cytochrome C of 40% or lower. The membrane is prepared by discharging a stock solution containing the polyarylate resin and the polysulfone resin in the total amount of 10% to 25% by weight and a core solution of an organic solvent containing water in the amount of 25% to 80% by volume into a coagulating solution.
