Title: Rotary shaft supporter
Inventor: FURUMURA KIYOUSABUROU
IPC: F16C33/10
Filed: 1982-02-10
Abstract: PURPOSE:To provide a rotary shaft supporter simple in the structure and small in size and suitable for mass-production by utilizing common effects of a plastic magnet and a dynamic pressure generating groove using a magnetic fluid as a medium. CONSTITUTION:A magnetic fluid filled in a gap between a rotary shaft surface 1a and a main body 12 of the bearing is completely arrested by a magnetic force of a plastic magnet 12. Particularly, since a magnetic flux having a highest density is formed at both end edges 20 and 21 of the main body 12 of the bearing, the magnetic fluid does not leach out of the bearing. In addition, when the shaft 1 rotates, a radial pressure is generated by the pumping operation of a dynamic pressure generating groove 13. However, since this pressure is highest at the central part of the main body 12 of the bearing and gradually decreased towards both ends, and the magnetic fluid 14 does not flow out to the outside during the rotation by the binding power due to the magnetic force.

IPC: F16D65/12
Filed: 1999-01-27
Abstract: PROBLEM TO BE SOLVED: To provide a brake disk of less bevel state deformation or the like, and of improved heat dissipation. SOLUTION: A brake disk 10 has a cover 12 made of casting aluminium alloy and a brake ring 14 made of cast steel or cast iron. The cover 12 is cast on a pocket 22. The pocket 22 has a pocket opening facing the inner side in the radial direction adjacent to a pocket end, and is formed on the inner periphery Ui of the brake ring to form a distance (b) between the cover 12 and the brake ring 14 in the radial direction. The pocket end is surrounded by the casting cover 12, and the pocket 22 is substantially filled with casting aluminium alloy. With this method for connecting the brake ring 14 to the cover 12, bevel state deformation can be remarkably avoided.

Title: Input circuit
Inventor: IGARASHI HATSUHIDE
IPC: H03K19/0185
Filed: 1991-02-13
Abstract: PURPOSE:To reduce the current consumption by connecting a 1st conduction type MOSFET between an element of a power supply side of an input circuit of differential amplifier circuit configuration and a power supply and connecting a 2nd conduction type MOSFET between an element at ground side and ground in series. CONSTITUTION:The input circuit is a differential amplifier circuit using a P- channel MOS field effect transistor (FET)Ma and an N-channel MOSFETM4 as differential inputs and an N-channel MOSFETM5 is a load. Furthermore, a P-channel MOSFETM1 is a current source at the source side. The FETM3 is a switch element and has a larger mutual conductance in comparison with that of the FETM5. In this case, with the MOS TR turned on, it is equivalent to the state that a drain of the P-channel MOSFETM2 connects to ground. Thus, when an input signal of the CMOS level is processed and the input signal is at a ground level or a power supply level, the power supply current flows to the input circuit.
