Filed: 1993-08-13
Abstract: PURPOSE:To provide a recording medium having excellent corrosion resistance and sliding reliability by forming many projecting parts on a protective film disposed on a magnetic layer and disposing a reformed layer having a hydrophobic property on this protective film. CONSTITUTION:This magnetic recording medium is constituted by disposing an intermediate layer 2 on an aluminum substrate 1 and forming a magnetic film 3 consisting of a Co-Cr system on this film 2 and the carbon protective film 4 thereon. The surface of the protective film 4 is provided with the many projecting parts. The projecting parts are formed to 0.1 to 10mum diameter 6, 3 to 120mum distances 7 between the projecting parts and the projecting parts and 5 to 30nm height 8 of the projecting parts. The reformed layer 5 is formed on the surface of the carbon protective film 4 formed with these projecting parts. The surface of the reformed layer 5 has the hydrophobic property and the contact angle with water is 45 to 70 deg. and the contact angle with glycerol is 35 to 55 deg.. While the resistivity of the protective film 4 is 10<6> to 10<7>OMEGAcm before reforming, the resistivity attains >=10<7>OMEGAcm after the formation of the reformed layer 5. The corrosion resistance of the protective film 4 is thus improved and the recording medium having the excellent sliding reliability is obtd.

Title: Developing device
Inventor: YAMASHITA HIROSHI
IPC: G03G15/08
Filed: 1993-08-16
Abstract: PURPOSE:To miniaturize a developing device and to suppress its cost by making a developer supply roller function as a peeling roller. CONSTITUTION:A switch 48 is turned off when an electrostatic latent image is developed by supplying toner 34 to a photosensitive drum 22, so that the surface potential of the developer supply roller 40 becomes the same potential of a developing roller 38. Thus, the toner 34 is frictionally electrified by the developing roller 38 and a thin layer of the toner is formed by a blade 42, thereafter the image is developed. On the other hand, when the development of the electrostatic latent image is finished, the switch 48 is turned on, and the surface potential of the developer supply roller 40 becomes 0V. Thus, the toner remaining on the developing roller 38 is peeled off.

Title: Hybrid ic device
Inventor: TANAKA KOUJI
IPC: H05K3/28
Filed: 1983-10-27
Abstract: PURPOSE:To obtain high reliability by preventing the break of solders connecting a substrate and an element due to thermal stress by a method wherein the gap between the substrate and the element is filled with an insulator having a coefficient of thermal expansion close to that of the solder. CONSTITUTION:The mixing ratio of the mixture 4 of alumina fine grains and a resin 5 is so set as to become close to the coefficient of thermal expansion of the solder 3. The gap between the substrate 1 and a flip chip 2 after they are soldered is filled with this mixture. The coefficient of thermal expansion of the mixture produced in such a manner can be varied according to the volume mixing ratio at the time of mixing the resin and the alumina fine grains: the coefficient can be made much closer to that of the solder. Therefore, the difference in the coefficient of thermal expansion between the solder and the mixture decreases, and generation of thermal stress diminishes, thus enabling the thermal fatigue of the solder to be prevented. At the same time, the mixing of the alumina fine grains with the resin increases the thermal conductivity and improves the heat dissipation of the chip.

In this case, the tape 2 rubs the outer circumference surface of the sleeve 13 fitted externally to pins 5 and 5' with prescribed contact pressure and at a fixed winding angle. Here the sleeve 13 is made of a nonmagnetic matter having a low frictional coefficient and high wear resistance to the tape 2 and therefore no electrification of the tape 2 is caused together with no deformation of both pins 5 and 5' due to their own friction. Thus the stable drive is secured with the tape 2.
