Title: Engaging fittings
Inventor: MORITA TAMAO
IPC: E05C19/16
Filed: 1981-12-16
Abstract: PURPOSE:To promote the desired magnetic shielding effect while the reduction in magnetic attaraction strength is suppressed by a method wherein the circumference of the contacting face of the male part, located in the female part case of the engaging fittings, is erected. CONSTITUTION:A ferromagnetic plate 3 is fitted in a non-magnetic case 4, the center hole of the plate 3 is contacted and engaged to the edge 4 of the case 4, a cylindrical permanent magnet 1 is pushed in, a pawl 4a is bent, and a female stop-fastener is completed. Then, said female stop-fastener is fastened to the surface of the mounting substrate such as a hand bag and the like in the same manner as the female stop-fastener using a mounting washer 6 having a frerromagnetic plate 5 to be contacted to the pole-face of the female stop-fastener in the state wherein the plate 5 is freely magnetized. Ferromagnetic sticks 2a and 5a are erected on the plates 2 and 5, and they are agnetized through the intermediary of holes 1a. When a protrusion 4c, which constitues a magnetic gap by erecting the circumference of the contacted end face of the plate 5 of the case 4, is formed in one body with the plate 5, the magnetic shielding effect by the plate 3 is encouraged by the protruded edge 4c, the contact of a magnetic recording part (cash card and the like) to the pole-surface of the magnet 1 or the plate 3 can be prevented, and the lateral shifting of the female stop-fastener can also be prevented.

Title: Thin film thermal head and its manufacture
Inventor: ENDO TOSHIYA
IPC: B41J2/335
Filed: 1990-08-01
Abstract: PURPOSE:To prevent unevenness of an electric resistance value of a heating element from occurring for each manufacturing lot by a method wherein the heating element is composed of a lower layer and an upper layer laminated on the lower layer, and an area resistance value of the lower layer is made larger than that of the upper layer. CONSTITUTION:Sputtering of a lower layer 3a is performed by using a Ta-SiO2 target, an Ar (pressure 6X10<-1>Pa) sputtering gas, and 1.6kW RF power. Besides, sputtering of an upper layer is performed on the lower layer 3a by using a target of Ta-SiO2 of all the same material and composition ratio as for the lower layer 3a, an Ar (pressure 1X10<-1>Pa) sputtering gas, and 1.6kW RF power. Further, a plurality of specific formed heating elements 3 are formed by etching or the like in that case. When films of the lower layer 3a and the upper layer 3b are formed by those conditions, specific resistance of the lower layer 3a becomes approx. 60mOMEGA-cm, and specific resistance of the upper layer becomes approx. 30mOMEGA-cm. Therefore, the area resistance value of the lower layer 3b becomes approx. 10 times that of the upper layer 3b. When a thermal head is driven, 90% or over of said making power is consumed by the upper layer 3b.

Title: Image transfer method
Inventor: HASEBE MITSUO
IPC: G03G15/16
Filed: 1986-08-29
Abstract: PURPOSE:To prevent toner on a supporting body from being reversely transferred on a photosensitive body without developing disturbance in an electrostatic latent image on the photosensitive body and to make it unnecessary to significantly raise a potential when an image is transferred several times by using as a power source for a transfer corona an AC with which a DC is overlapped. CONSTITUTION:Resultant obtained by overlapping AC and DC voltages is used as the power source for the transfer corona impressed on the supporting body 6 such as paper. In a succeeding processes t2-t3 where the supporting body adheres to the photosensitive body and then is gradually separated from said body, a surface potential V rises. However, as an AC corona is discharged, a high potential part is destaticized, and a charge density rho decreases so that it can stand at a fixed potential not exceeding an air insulating destruction point. Consequently, there are no phenomena such as the disturbance of a latent image on the photosensitive body, which is caused by air discharge along with an increase in the potential, and the reverse transfer of toner on the supporting body to the photosensitive body. If a voltage has to be raised sequentially at a time when one latent image is transferred several times and when the image is transferred on one supporting body, a normal level suffices.
