Title: Lru cache managing method
Inventor: KEBIN FURANKU SUMISU
IPC: G06F12/0888
Filed: 1990-04-03
Abstract: PURPOSE: To maximize the number of hits of a cache while keeping the priority by sectioning the cache and arbitrarily assigning a target hit rate and periodically monitoring the actual hit rate related to each section in a reference cycle. CONSTITUTION: When an LRU cache is managed, the cache is sectioned, and the target hit rate is arbitrarily assigned. In the succeeding reference cycle, the actual hit rate related to each section is periodically monitored, and the size of each cache section is changed as a function of the difference with a sign between actual and target hit rates. With respect to the change, the positive difference reduces the section side, and the negative difference increases it. Thereafter, priority classes of data referred by a host are confirmed for a staging type storage system, and finally, sections 1 to N related to confirmed priority classes 1 to N or the staging type storage system is referred to. Thus, the hit rate of the cache is improved while keeping the priority.

Title: Apparatus for measuring reflection density
Inventor: YASUDA YOSHIHIKO
IPC: G01N21/78
Filed: 1986-04-16
Abstract: PURPOSE:To continuously measure reflection density by deforming a bundle fiber, by connecting a measuring head to a light source with the bundle fiber of optical fibers and allowing light to pass through the bundle fiber to irradiate a chemical analysis slide to perform measurement. CONSTITUTION:A plurality of chemical analysis slides 1 are housed in an incubator 2 and a light source 3 is connected to a measuring head 6 by a bundle fiber 4 of optical fibers. Light is allowed to pass through the bundle fiber 4 to be sent to the measuring head 6 and irradiates the chemical analysis slides 1. The reflected light from each slide 1 is received by the optical sensor 5 of the measuring head 6 to analyze the specimen on the chemical analysis slide 1. At this time, a fibers having a small diameter are used to minimize the loss of light due to bending and the bundle fiber 4 is deformed to allow the measuring head 6 to move as shown by an arrow in opposed relation to the slide 1 to perform measurement. Because the measuring head is moved by deforming the bundle fiber, the chemical analysis slide can be measured continuously.

Title: Method and device for associative storage
Inventor: SHIMAZU HIDEO
IPC: G11C15/04
Filed: 1990-04-03
Abstract: PURPOSE:To attain the associative/reminding operations by comparing an assembly of microfeatures corresponding to the notions with an assembly of microfeatures corresponding to the original notions respectively and defining the notion containing the largest number of minute feature elements having the coincidence with presence/absence of existence as the notion that is associated/reminded from an original notion. CONSTITUTION:The associating/reminding notions are stored in an original notion storing means 1 in the form of the assembly of microfeatures. Then the expressions showing the present viewpoints are stored in a present viewpoint store means 2 in the form of an assembly of microfeatures by reference to a multi-viewpoint definition store means 6. A noted feature selection means 3 outputs the partial assembly of microfeatures coincident with the assembly of microfeatures stored in the means 2 out of the assembly of microfeatures stored in the means 1. Furthermore an associative notion selection means 5 selects only the notion including the partial assembly of microfeatures outputted from the means 3 out of a multi-notion definition storing means 4 and outputs this selected notion. Thus the associating/reminding operations can be facilitated.
