Title: Composite roll
Inventor: HISADA TAKEO
IPC: B21B27/00
Filed: 1994-03-30
Abstract: PURPOSE:To provide a composite roll hard to subject to defect/fracture. CONSTITUTION:In the composite roll in which a sintered body layer 3 of wear resistance material is diffusion joined on the surface of a core material 1 by HIP and is made to a rolling surface, the end face in roll axis direction of the sintered body layer 3 is covered with the core material 1. In this composite roll, the sintered body layer 3 is compressed from the end faces resulting from contraction of the core material 1, the tensile stress generated by heat treatment in production process is suppressed to smaller, that is, P1 (<P2). Also, the end faces of sintered body layer are located more to inside than the corner part of roll, the end part of sintered body layer is gradually cooled from surface in the same as other parts, unevenness in structure is hard to be generated, thus generation of crack is prevented. In addition, a wear resistant material is exposed at a corner part, in the case that a corner part of roll is erronously collided, there will be no crack.

Title: Electromagnetic driver circuit
Inventor: ENOKIDO SUSUMU
IPC: H01F7/18
Filed: 1978-05-22
Abstract: PURPOSE:To attain both economization and miniaturization by preventing malfunction due to a break of the power supply of an electronic system, by connecting a transistor, with the photo detector of a photo coupler connected between the base and emitter, between the emitter and base of the transistor at the 2nd stage. CONSTITUTION:When input IN as information of the electronic system changes from Low to High, the output of inverter element INV changes from High to Low and light emitting element D of photo coupler PT turns ON. As a result, photo detector TR of PT also turns ON and the 1st-stage transistor TRO with photo detector TR connected in parallel between its base and emitter turns OFF. With TRO OFF, a current flows via resistance R2 between the emitter and base of the 2nd-stage transistor TR1 with the emitter and collector of TR0 connected in parallel between the emitter and base of TR1, and consequently an amplified current flows between the collector and emitter, thereby operating relay A.

Filed: 1999-03-10
Abstract: PROBLEM TO BE SOLVED: To prevent the accumulation of fine grains included in the slurry liquid for a long time by providing a specified relation between a total value of passage cross sectional area of plural grooves and a clearance area between the inner periphery of a drive collar and the outer periphery of a rotary shaft. SOLUTION: In the case where passage cross sectional area of one groove 7a is expressed with S0, total value S1 of the passage cross sectional area of the all grooves (six grooves in this invention) 7c is expressed with 6S0. An annular clearance area S2 is secured by a clearance G between the inner periphery of a drive collar 7 and the outer periphery of a rotary shaft 2. These S1 and S2 have the relation that S1<=S2<3S1. In order to sufficiently show the centrifugal pump work by the groove 7c, a clearance area S2 more than the total value S1 of the passage cross sectional area is necessary. In case of S2<S1, sufficient work of the centrifugal pump is hindered by the fluid resistance of the clearance G. On the other hand, in the case where the clearance area S2 is too large, accumulation of fine grains is easy to be generated.  Consequently, in the case where the relation S1<=S2<3S1 is satisfied, fluid fluently flows, and discharged outside of the groove 7c without generating accumulation of the fine grains.
