Title: Intensity evaluating method of magnetic disk
Inventor: ITOSATO AKIRA
IPC: G11B5/82
Filed: 1979-06-20
Abstract: PURPOSE:To secure a quick evaluation for the durable intensity of the magnetic disk, by attaching the low-floatup head in the opposite direction to the normal way onto the magnetic disk of the magnetic disk device of contact start-stop (CSS) system and then repeating the CSS of the magnetic disk. CONSTITUTION:Low-floatup head 1 having about 0.3-0.1mum floating amount is used. Then head 1 is attached onto magnetic disk 4 in the opposite direction to the normal way and so that air flow-in end 3 of slider taper part 2 of head 1 may be at the flow-out side. Under these conditions, the contact start-stop (CSS) of disk 4 is repeated to give the evaluation to the durable intensity of disk 4. In that case, the rotational direction of disk 4 is shown by the arrow. When head 1 is attached in the opposite direction to the normal way, the floating position of head 1 becomes unsteady. Thus head 1 hits frequently the surface of disk 4. In such way, the durable intensity of the magnetic disk can be evaluated in about 1/10 the conventional time.

Title: Semiconductor integrated circuit
Inventor: IWASAKI TOMONOBU
IPC: H01L21/82
Filed: 1988-03-30
Abstract: PURPOSE:To reduce a boundary space and to decrease a layout area by so laying out a plurality of drive circuits formed of PchTrs(P-channel transistors) and buffer circuits to be disposed adjacently. CONSTITUTION:The source of s PchTr1 is connected to a power source Vcc, and the output of an AND item is input to the gate of the PchTr1. The drain of the PchTr1 is wired to a word line of OR item through a second wiring layer designated by a shaded part. Thus, in an array circuit such as a ROM, PLA(Programmable Logic Array), the PchTr of the circuit for driving a work line of the OR item is not laid between the AND ltem and the OR item, but is laid at the opposite side to the AND or OR item. Thus, the boundary space to be obtained between the NchTr and the PchTr is drastically reduced, thereby decreasing the layout area.

SOLUTION: A part on the inner periphery side from a sliding surface 2 of a disc and a plate part 33 close to a boss outer surface 36 of a wheel are fastened by a bolt 4 and a nut 5. Thus, the movement toward axial and rotating directions of the disc is restricted to fix the disc to the wheel. If suitable restriction is not applied, the disc is deformed as it is used to cause a warp. Then, a ring 7 is inserted in a ring insert hole formed grooves 8, 9 provided in the outer peripheral surface 3 of the disc and the rim inside diameter surface 32 to form an obstacle. By the ring, deformation of the disc can be controlled to reduce load on the bolt due to deformation of the disc.

Title: Constant velocity joint
Inventor: ASANO HIROAKI
IPC: F16D3/227
Filed: 1989-03-28
Abstract: PURPOSE:To reduce the sliding friction of balls so as to reduce the vibration by alternately providing two different sizes of torque transmission balls between inner and outer joint members, and by enlarging axial clearance in retaining hole which has smaller radial clearance between ball retaining hole and ball. CONSTITUTION:Providing a driven shaft A with inner joint member 1, and a main driving shaft B with outer joint member 2, larger balls 41 and smaller balls 42 retained in a cage 3 are alternately provided therein. Retaining holes 3a and 3b are formed through the cage 3 between its outer surface 31 and its inner surface 32. An axial clearance between the larger ball 41 and retaining hole 3a is larger than the same between the smaller ball 42 and the retaining hole 3b. consequently only larger balls 41 having smaller radial clearances are slightly elastically distorted to transmit a torque from the main driving shaft B to the driven shaft A in rather lower torque state, thereby producing vibration or ball sliding between the shafts only for the larger balls to reduce the vibration or noise by half. for higher torque drive, further elastic distortion of the larger ball allows the smaller ball also to bear its excess load, thereby enabling to withstand the load sufficiently.
