A source facsimile machine has a function of ending a retransmission process when image data related to error-free frames cannot be received at a destination facsimile machine. The destination facsimile detects an error in each of lines of the frame and records the error-free lines. Hence, even when errors exist in the received frames, it is still possible to record the received image by recording the error-free lines. In other words, the detination facsimile can record the received image with a minimum dropout of image information caused by the errors in the received frames.
摘要:
A variable capacitance type encoder for measuring the length of an object to be measured on the basis of detecting the amount of movement of a probe as a function of the variation of electrostatic capacity between a rotary disk which is secured to a shaft and a pair of fixed disks which are secured to a frame body so as to be opposed to the rotary disk. On at least one fixed disk is provided first and second transmitting electrodes composed of a plurality of electrode elements to which voltages of different phases are applied. The rotary disk is provided with first and second receiving electrodes for receiving signals of a common phase by electrostatic coupling with both transmitting electrodes. Each fixed disk is further provided with an output electrode which is electrostatically coupled with the respective receiving electrode.

In manufacturing a magnetic recording medium, a flow of iron vapor is formed in a nitrogen atmosphere and iron vapor particles in the flow of iron vapor are deposited on a non-magnetic substrate together with nitrogen particles to form an iron nitride film thereon. Before deposition on the non-magnetic substrate, the nitrogen particles are ionized by an ion beam generating means and the iron vapor particles are ionized by a high-frequency discharge.

A magnetic recording medium comprises a non-magnetic substrate, a thin ferromagnetic film layer overlaid on the substrate, and a polymer film formed by plasma polymerization. The thin ferromagnetic film layer is composed of ferromagnetic columnar grains. The polymer film is overlaid on the thin ferromagnetic film layer so as to permeate into the spaces between the ferromagnetic columnar grains, thereby improving the corrosion resistance and durability of the magnetic recording medium.
摘要:
A process for forming an ultrafine pattern on a surface of a substrate, which includes steps of irradiating the substrate surface with radiation modulated according to information to be patterned, subjecting the substrate surface to deposition with a material reactive or not with the substrate, and subjecting the substrate surface to etching if a substrate-reactive material is used for deposition. By this process, an ultrafine pattern can easily be formed with a high accuracy.
