Title: Manufacture of superconductive fiber
Inventor: FUKUDA KATSUYOSHI
IPC: H01B12/04
Filed: 1987-06-12
Abstract: PURPOSE:To manufacture a pluralistic oxide fiber uniformly in the longitudinal direction with generating no breaking during the manufacture by covering the surface of a material core with a specific metal element or an alloy including the metal element, melting it, and introducing the metal element into the material core in the liquid phase diffusion. CONSTITUTION:The surface of a material core 33 is covered with a specific metal element or an alloy including the metal element and melted. And the metal element is introduced into the material core 33 in the liquid phase diffusion. And by applying an electric field to true up the crystalline direction when a fiber is extended, a high quality fiber with an even composition element ratio in the longitudinal direction of the fiber can be manufactured. Since the surface of the produced fiber is covered with a component metal or an alloy including the component metal which is stronger against the breaking than a crystalline pluralistic oxide, the fiber is prevented from breaking owing to the temperature variation during the manufacture and owing to a bending stress when the fiber is wound on a drum.

IPC: H04L1/16
Filed: 1978-11-27
Abstract: PURPOSE:To realize a high-speed process for the data in a simple and low-cost constitution by sending back the answer signal only in case no error is detected in the reception data block at the reception side and then transmitting again the data at the transmission side only when no answer signal exists. CONSTITUTION:The ACK signal of the single frequency is transmitted to the transmission sode from affirmative answer character ACK signal generator circuit A only when no error is detected through error detector circuit E for the data blocks which are received in sequence at the reception side. While at the transmission side, the answer signal is detected at detector circuit D, and then the next data of buffer B2 is read out through buffer reading control circuit BR and based on the output signal. And the block number is given at transmission data formation circuit N for transmission of the data. No ACK signal is delivered at the reception side when some error is detected at the block data, and thus detector circuit D of the transmission side detects the error. And circuit BR gives switching to buffer B0 again after transmission of data BL1 to transmit data BL0 again.

Title: Printing head
Inventor: OTA YOSHIAKI
IPC: B41J2/265
Filed: 1989-06-07
Abstract: PURPOSE:To improve a head in frequency characteristics by a construction wherein, in a printing head of two-line staggered hammer-drive type, a distance between a right wire top and a left wire top is determined so as to realize a minimum hammer wire drawing amount. CONSTITUTION:A distance D11 between a right hammer wire 5 and a left ham mer wire 5 is determined to be larger than that of a prior art (Fig.2). In the prior art, hammer wires 9 are forcibly drawn by intermediate guides 6, 7, 8. Thus, a head nozzle length Y21 that is not sufficiently long causes the breakage of a wire. As a result, the long wire 9 deteriorates frequency characteristics. However, in a Fig.1, the distance D11 is determined so as to meet X21=X22, the hammer wires 5 are drawn by a uniform amount by intermediate guides 3, 4, and a head nozzle length Y11 is made shorter. Namely, the frequency characteristics is improved by the amount in compliance with the reduction of the hammer wire 5 in length.
