Abstract: PURPOSE:To produce iron and steel members with high-adhesiveness coating films with high productivity by executing vacuum arc discharge with Cr as a cathode and successively executing Cr bombardment of a high bias voltage, Cr formation of a low bias voltage and formation of a CrN layer. CONSTITUTION:The Cr cathode 5 and the iron and steel members which are cleaned and are attached to a substrate 8 are disposed opposite thereto in a vacuum vessel 4 evacuated to about 10<-5>Torr of a vacuum arc discharge type PVC film forming device. About -2,000V bias voltage is impressed to the above-mentioned substrate 8 and a voltage is impressed to the Cr cathode 5 by a power supply 6 to execute the arc discharge and to generate Cr ions so that the surfaces of the iron and steel members are sputtered. The bias voltage is made to about -50V after this Cr bombardment and the Cr layer is formed to about 500-1,000Angstrom  on the surfaces of the iron and steel members. N2 is thereafter introduced from a gas introducing port 11 into the vacuum vessel and the CrN layer is formed on the above-mentioned Cr layer under about 5X10<-4>Torr gaseous N2 pressure and at about 40A arc current and about -50V bias voltage. The iron and steel members with the coating films consisting of the intermediate layer of the Cr and the surface layer of the CrN are thereby obtd.

Title: Manufacture of plastic lens
Inventor: NAITO SHUJI
IPC: G02B3/00
Filed: 1998-03-11
Abstract: PROBLEM TO BE SOLVED: To prevent the generation of the unevenness in the ultraviolet ray absorbing power and the surface roughness and to uniformly disperse an ultraviolet ray absorbent into the water by dispersing the ultraviolet ray absorbent into an aqueous solution after the disperse dye treatment, and dipping a plastic lens into the aqueous solution to provide the lens with the ultraviolet ray absorbing power. SOLUTION: A ultraviolet ray absorbent is dispersed into the water after the disperse dye treatment, and a lens is dipped in this aqueous solution. That is, by performing the disperse dye pretreatment to the ultraviolet ray absorbent which is originally inferior to the dispersibility in the water, the ultraviolet ray absorbing power can be applied to the lens similarly as the conventional plastic lens dyeing method. The ultraviolet ray absorbent is uniformly impregrated from a lens surface in the water, so that the ultraviolet ray absorbing power can be uniformly and fully applied to the lens. The ultraviolet ray absorbent is uniformly dispersed in the water, so that the generation of the surface roughness caused by the cohesion of the ultraviolet ray absorbent on the lens surface can be prevented.

IPC: H04L5/16
Filed: 1980-05-07
Abstract: PURPOSE:To facilitate a synchronism for the data of a terminal device, by installing an integral network at the two-way communication line of a semidouble communication system and thus performing a control of the output signal and an inhibition of the signal supplied from the other side through the said integral network. CONSTITUTION:A bit synchronism is secured at a terminal device when the data is transmitted to the terminal device from the center side, and thus a clock signal of idling is transmitted. When the signal is supplied to a data repeating device 10, the input signal is amplified by a line receiver 21a. The output signal of this amplification is supplied to an integrator 24a via an AND circuit 22a as well as to a line driver. The integrator 24a functions as a delaying circuit and thus delivers no clock signal while it functions as a delaying circuit but delivers the data only. At the same time, the integrator 24a sets the line driver under a high output impedance state during a delaying action and amplifies only the signal delivered from the center side to transmit it to the terminal device.
