Title: Magnetic recording medium
Inventor: HANADA KAZUYUKI
IPC: C09D5/23
Filed: 1986-03-24
Abstract: PURPOSE:To permit the use of various binder resins and to obtain a recording medium having a low coefft. of friction by modifying the binder resin by using a specific modifying agent at the time of producing the magnetic recording medium. CONSTITUTION:A magnetic layer is formed on one face of a nonmagnetic base by using a dispersion of magnetic particles of iron, etc., binder resin such as vinyl chloride, the modifying agent thereof and medium. The modifying agent is prepd. by adding a methyl ethyl ketone as a solvent to an amino acid modified Si oil having a reactive org. functional group and phenyl isocyanate, adjusting the ratio of the org. functional group/isocyanate group to 1 or above and treating the mixture thereof at 20-80 deg.C. The mol.wt. thereof is adjusted to <=50,000. The compsn. of the dispersion is selected to 10-50wt% magnetic particles, 1-50wt% modifying agent by the weight of the binder resin, 50-90% medium and 5-20wt% binder resin. The medium may be an org. solvent to be used in the stage of preparing the modifying agent. The high-quality magnetic recording medium is obtd. by using the various binder resins without being limited by the conventional polyurethane resin according to the above-mentioned constitution.

Title: Manufacture of surface protecting member
Inventor: SATSUMA MICHIO
IPC: B32B7/00
Filed: 1988-03-16
Abstract: PURPOSE:To make it possible to smoothly detach an adhesive layer accompanied with a protective film without leaving an adhesive paste behind when said protective film is peeled off from an object to be protected, by providing said adhesive layer in a predetermined thickness to said object to be protected and then, attaching said protective film to said adhesive layer. CONSTITUTION:The thickness of an adhesive layer provided in an object to be protected is 0.1-10mum. If the thickness of the adhesive layer is smaller than 0.1mum, the adhering force of the adhesive layer to a protective film is insufficient. If the thickness of the layer is greater than 10mum, it tends to cause that the adhesive paste is left behind when the adhesive layer is detached from the object to be protected. A protective film is attached to the thin layer of the adhesive provided in the object to be protected. As a result, such a surface protecting member is obtained that is superior in the initial adhering force, less in rise of the adhering force with time, with good readiness in exfoliation. Moreover, to be unexpected, the adhesive layer can be removed off together with the protective film from the object to be protected, without leaving the adhesive paste behind. Further, an appropriate balance can be maintained between the adhering force the readiness in exfoliation so that the surface protecting member can be changed in shape without breaking the protecting film or without generating wrinkles, flashes, levitations, etc., causing the separation of the protective film therefrom.

Title: Viscous coupling
Inventor: HAGIWARA MAKOTO
IPC: F16D35/00
Filed: 1990-03-16
Abstract: PURPOSE:To improve torque interruption performed by a built-in clutch and response to interruption by providing an outer-operatable locking means for pressing clutch plates in order to adjust transmission power between the plates and transmission members for locking, and also providing a passage for leading a viscous fluid between both contact parts. CONSTITUTION:When a pressing member 43 moves forward, plates 55, clutch plates 61 and spacers 63 are pressed between the pressing member 4 and a snap ring 66 to connect a multiple disc clutch 59, and the plates 55 are connected to a hub 25. When the pressing of the pressing member 43 is released, the multiple disc clutch 59 is released, and the plates 55 are spaced from the hub 25. At the connecting and connection-releasing time of such a multiple disc clutch 59, silicone oil from a slit 69 and a groove 73 is discharged from or flows into a contact part 79 formed among the plate 55, clutch plate 61 and spacer 63. The operation delay of the multiple disc clutch 59 caused by the viscosity of silicone oil is therefore shortened to improve response to torque interruption.

Title: Photodetector
Inventor: NISHI TSUTOMU
IPC: G01J1/42
Filed: 1990-03-15
Abstract: PURPOSE:To prevent erroneous operation by operating a discharge transistor by the comparison output of a comparator circuit, ad instantaneously discharging the charge in a coupling capacitor CC after the generation of powerful external light. CONSTITUTION:When powerful external light shown by a void arrow a is generated, the control current from a light receiving diode 3 is rapidly increased. The charge corresponding to the voltage across both ends of a bias resistor 6 and a detecting resistor 8 is charged into a CC 5. Therefore, even if the diode 3 is conducted by the light emission of a LED 2, the AC component of the control current is limited in comparison with an ordinary value. Thus, the voltage is not outputted from an output transistor 4. Meanwhile, a comparing voltage VCP is also increased and becomes larger than a reference voltage VREF. Therefore, discharging transistors 14 and 15 are conducted by the output of a comparator circuit 12. When the generation of the external light is stopped, the charge in the CC 5 is instantaneously discharged through the resistor 13 and the collectors and the emitters of the transistors 14 and 15. The output pulse voltage corresponding to the light emission of the LED 12 is obtained from the transistor 4.

Filed: 1979-05-26
Abstract: PURPOSE:To prevent the wear of a steel pipe because of friction with fluid, by quenching the inner surface of the steel pipe such as a penstock which has been melted by arc heat so as to harden the inner surface of the steel pipe. CONSTITUTION:Inner surface, which needs to be hardened, of a pipe 1 made of carbon steel or low alloy steel, or inner surface of joined part of the pipes, is hardened in order to prevent the wear caused by the passage of fluid. For that purpose, an electrode 3 of a TIG welding set 2 is arranged at the inside of the pipe 1 with the electrode 3 directed to the inner surface. An electric arc is generated between the electrode 3 and the inner surface of the pipe 1 while revolving the pipe 1 at a low speed around the axis, and at the same time while spraying Ar gas through a nozzle 5 which surrounds the electrode 3 thereby melting locally the inner surface of the pipe. The melted portion is exposed to air and is cooled rapidly by the revolution of the pipe to form martensite structure and hardened. This pipe hardly wears by the passage of fluid, so that the life time of a penstock is extended.
