Patent JP-S6390717-A (JP)
Title: Optical encoder
Inventor: NOZAKI KAGEHARU
IPC: G01D5/36
Filed: 1986-10-03
Abstract: PURPOSE:To obtain a displacement detection output with high resolution by allowing four division detectors to detect optically a code pattern which is formed repeatedly at intervals narrower than the spot diameter of laser light projected on a code plate, and composing an encoding output of respective detection outputs. CONSTITUTION:The photodetector 29 of an optical pickup 20 generates two- phase sine wave detection outputs A-D corresponding to the code pattern 11 by four division detectors 29A-29D, whose in-phase components are put together. Further, the addition composite outputs SC and SD are processed by subtraction to obtain a stable sine wave subtraction composite output SF while canceling offset variations of the respective outputs. The waveform of the subtraction composite output SF is shaped by a waveform shaping circuit 35A. Consequently, an encoding output corresponding to the code pattern formed on the code plate 10 is obtained.

Title: Spindle motor
Inventor: OGATA MASAAKI
IPC: H02K21/22
Filed: 1996-09-05
Abstract: PROBLEM TO BE SOLVED: To provide a constitution capable of stabilizing the deflection of the axis of the rotary shaft, in a spindle motor of such type that the rotary shaft is supported by a sintered oil-retaining bearing. SOLUTION: In a spindle motor, the bearing material to support the rotary shaft 30 is a sintered oil-retaining bearing, so deflection occurs at the rotary shaft 30, being caused by clearance. Nevertheless, an eccentric hole 910 is made at the disc table 91 fixed to the rotary shaft 30, and the rotor is constituted positively so as to be of eccentric structure, so the rotary shaft 30 only causes periodic procession even if it deflects. If it is the deflection of drawing such a regular locus, the optical head can be made to follow the motion of a disc, so there is no hindrance in reproduction of information from the disc.

Title: Magnetic disk device
Inventor: ARAI TAKESHI
IPC: G11B21/08
Filed: 1985-10-23
Abstract: PURPOSE:To omit the receiving time of a pulse train as the waste time and to accelerate the access time by starting the shift of a head before all pulse trains are through as a head shift instruction. CONSTITUTION:A pulse train 7 sent from an upper position counts up a counter 6 and the contents of the counter 6 are sent to a target speed producing part 4. A voice coil motor (VCM) 1 is driven by the current produced at a drive current generating part 5. Then a pulse is produced every time the VCM moves by one track and the shift amounts of the VCM1 are counted by a counter 3. The part 4 calculates a target speed from the difference of contents between both counters 3 and 6. While the part 5 produces a current in response to the target speed. Here the part 4 produces the maximum speed if the difference of contents between both counters is larger than a fixed level and then produces a speed corresponding to the speed curve if said difference of contents is less than the fixed level.
