Title: Magnetic disk device
Inventor: KANEKO JIRO
IPC: G11B17/028
Filed: 1995-12-18
Abstract: PROBLEM TO BE SOLVED: To make the device small in size and thin in thickness with high reliability by making the inner diameter of a clamp member large on the side of an unfixed member and small on the other side and fixing the clamp member by press-fitting. SOLUTION: The inner diameter of the disk clamp 3 is tapered, and the size on the side 301 of the small diameter is made smaller than the external size of an inserting part of a top part of a hub 2. Then, by press-fitting the disk clamp 3 onto the hub 2, a magnetic disk 1 is pressed in the shaft direction and is also fixed to the hub 2. In this fixing state, the disk clamp is given force in the radial direction only on its side 301 opposite to the magnetic disk, subduing the hub 2 and vice versa. Consequently, the disk clamp 3 is deformed to be projected upward. Thus, since the magnetic disk 1 is surely pressed by the outer circumference of the disk clamp on the magnetic disk side 302, the stable clamping force can be obtained.

Title: System for reading scanning type image sensor
Inventor: HOSHINA NAOYUKI
IPC: H04N1/409
Filed: 1987-12-24
Abstract: PURPOSE:To improve the S/N and gamma characteristics of a sensor output by switching sensor blocks by means of a multiplexer in a peak holding reset cycle. CONSTITUTION:After a peak hold reset, an amplifiers is switched by the multiplexer, the switching noise of the multiplexer is prevented from getting on a peak holding output, and an influence upon the peak holding processing of a next bit is suppressed. For such a reason, a timing constitution is made so that the timing of the amplifier changeover of the multiplexer is regulated and the peak holding reset is executed before such a time. For example, the timing constitution is adopted so that the amplifier changeover by the multiplexer is executed 800n sec after from the start of a clock and the peak holding reset is executed 100n sec before, namely, 700n sec after from the clock start.
