Title: Disk cache enhancer with dynamically sized read request based upon current cache hit rate
Inventor: O'NEIL JOHN T
IPC: G06F12/08
Filed: 1998-12-29
Granted: 2000-12-01
Abstract: The performance of a disk cache subsystem is enhanced by dynamically sizing read requests based upon the current cache hit rate. Accordingly, the size of the read request depends upon at least one variable factor other than the size of the requested data. More specifically, the size of the read request is reduced as the cache hit rate declines, and the size of the read request is increased as the cache hit rate increases. Short-term and long-term cache hit rates are tracked. The short-term cache hit rate is used to determine the reduction in the size of the read request, and the long-term cache hit rate is used to determine the increase in the size of the read request. The read request is a read-around request formulated to obtain the immediately requested data, plus additional data which is not requested and which is located before and after the immediately requested data. When used in a Windows operating system environment, the initial read-around value is about 1 megabyte.

Inventor: OTTESEN HAL HJALMAR
IPC: G11B5/596
Filed: 1999-10-20
Granted: 2001-10-21
Abstract: A method and apparatus for identifying and filtering a resonance frequency of a support structure supporting a read/write head in proximity with a data storage medium involves obtaining a particular sample of a position error signal (PES) frequency transform, preferably using Goertzel's algorithm. The velocity of the data storage medium is varied, and the magnitude of a particular PES frequency transform sample is computed at each of the velocities. A resonance frequency of the support structure is calculated using the velocity associated with the particular sample having a maximum magnitude. The effects of one or more resonance frequencies associated with a read/write head suspension may be canceled in a position error signal using one or more programmable filters provided in each servo loop. A processor programs the filters using the calculated resonance frequencies and adjusts to compensate for the additional lag introduced into the respective servo loops by the selected programmable filters. A method and apparatus for identifying one or more resonance frequencies of one or more read/write head support structures according to the principles of the present invention may be implemented in a data storage system and, preferably, implemented in-situ a data storage system without resort to circuitry external to the data storage system.

Title: Manufacturing method of the semiconductor device
Inventor: KUWABARA OSAMU
IPC: H01L23/12
Filed: 2000-08-17
Granted: 2001-11-21
Abstract: A sealing film is formed by a screen printing method. In this case, the temperature of the printing table is set at about 30 to 50 DEG C by the heat generation from a planar heater arranged within the printing table. A liquid sealing resin having a relatively high viscosity of about 500,000 to 1,500,000 cPS is used for forming the sealing film. However, the liquid sealing film is warmed by the printing table to about 30 to 50 DEG C. As a result, the viscosity of the liquid sealing resin is lowered to about 50,000 to 200,000 cPS. After the curing, the viscosity of the sealing film is brought back to the original value of about 500,000 to 1,500,000 cPS.
