Title: Chain for friction type continuously variable transmission
Inventor: NAKAMURA SEIJI
IPC: F16G5/18
Filed: 1993-06-25
Abstract: PURPOSE:To increase pressure contact force by linear contact with the power transmission face of a V-pulley so as to enlarge power transmission force and reduce noise by using block members of elliptic cross section with both ends of blocks, which are the contact parts with the power transmission face of the V-pulley, formed into linear wave shape. CONSTITUTION:A chain 101 is connected by blocks 103 of approximately elliptic shaft-through cross section with both end faces having the contact faces inclined at the same angle as the power transmission face of a V-pulley and also by link plates 102 connected endlessly in numerous rows through the blocks 103, and held by holding members 104. The end faces of the block 103, that is, the contact faces 106a, 106b with the power transmission face of the V-pulley, are formed into planes coinciding with the angle formed by the power transmission face the V-pulley so as to come in linear contact and to receive pressure contact force, thus transmitting torque by frictional force related to the frictional coefficient of the contact parts. The contact area is thereby enlarged so as to receive high pressure contact force, and the generated frictional force is also increased so as to enable the transmission of large power.

Title: Thin-film magnetic head for perpendicular recording
Inventor: TAKAGI HITOSHI
IPC: G11B5/31
Filed: 1989-07-13
Abstract: PURPOSE:To improve the reliability of perpendicular magnetic recording by providing a sensor member for detecting external magnetic fields perpendicular to the magnetic medium and connecting the member to an external circuit in such a manner as to allow the generation of a magnetic field for correction in the direction where the detected external magnetic field is negated. CONSTITUTION:A terminal 43c of an analog switch 43 is connected to a terminal 43a by the instruction of a control circuit 46 in an external magnetic field detecting mode and, therefore, one end of the sensor 30 is connected to a constant current source 41 and a sample-hold circuit 44 and a current flows to the MR element 31 of the sensor 30. The MR element 31 is changed in electric resistance by the external magnetic field and the DC potential for monitoring corresponding to the intensity of the external magnetic field in the direction horizontal with the medium film surface is obtd. by impressing a bias magnetic field thereto in order to make linear operation. Since the external floating magnetic field near a main magnetic pole 4 can be corrected, the concentration of the magnetic flux to the main magnetic pole by the floating magnetic field is lessened. As a result, the demagnetization and degaussing of the information recorded on the magnetic recording medium are prevented. The thin-film magnetic head for perpendicular recording having the high reliability is obtd. in this way.

Filed: 1982-10-14
Abstract: PURPOSE:To manufacture a metallic thin film magnetic recording medium having low cost, high performance and high durability by binding, holding and heat-treating the magnetic recording medium so as not to be contracted in air, after the magnetic recording layer is formed. CONSTITUTION:In the binding and holding, the contraction to a degree where no crack of metallic thin film is produced and no flaw of the medium is produced is allowed. In case of a plate shaped medium such as floppy disc, a mating projection 11a and a recess groove 12a are provided to a holding plane of a pair of ring shaped metallic frames 11, 12 so as to clip the circumference of the medium 10 by the metallic frames 11 and 12. Thus, the entire circumference of the medium 10 is bound and held in air by the metallic frames 11, 12. If the temperature of the heat treatment is too high, even when the film is bound to be in a state not to be contracted, cracks are produced on the metallic thin film because of the local contraction of film and expansion. Thus, the heat treatment temperature is suitably 120 deg.C-210 deg.C.
