Title: Storage device using flash memory, and its storage control method
Inventor: ACHIWA KIYOUSUKE
IPC: G06F12/02
Filed: 1994-06-29
Abstract: PURPOSE:To suppress variance in erasure frequency among physical blocks of sector constitution by assigning a logical block which belongs to a group that is high in write frequency to a physical block which belongs to a group which is low in erasure frequency. CONSTITUTION:A logical block space viewed from a host computer and the physical block space of an actual flash memory are held as management information on the write frequency of a logical block 1100 while made to correspond to each other. When a request to write a logical block 1100 which is large in write frequency and corresponds to a physical block (old physical block 200) of high erasure frequency is made, a physical block (copy source physical block 2020) of low erasure frequency corresponding to the logical block 1100 of low write frequency is searched for and a free physical block belong to the same erasure frequency group with it is decided as a written physical block 2010, in which write data are written. Then the data written in the copy source physical block 2020 are copied to a copy destination physical block 2030.

Title: Storage information readout circuit
Inventor: TANAHASHI YUTAKA
IPC: G11B20/10
Filed: 1986-06-24
Abstract: PURPOSE:To attain noise rejection on a base line and accurate peak position detection by eliminating a DC component of a reproduced analog signal, applying half-wave rectification to the result, extracting only a half wave in the peak polarity direction only, and using the resulting signal for an object of peak detection by a differentiation circuit and a comparator circuit. CONSTITUTION:A read analog signal (a) is fed to a half wave rectifier circuit 4, where only a positive half waveform is detected based on a zero level corresponding to a peak direction polarity of the read analog signal (a) to obtain a detection signal (b). Then the detection signal (b) is subject to time differentiation by a differentiation circuit 5 and a differentiation signal (c) being its output has a waveform in which a peak point of the read analog signal (a) is converted into a zero cross point. That is, the positive peak point of the read analog signal (b) being '1' information is coincident with a positive peak point of the detection signal (b) and further coincident with a position crossing the zero level from the positive to the negative level of the differentiation signal (c). Since the differentiation signal (c) is fed to one input of the comparator circuit 6 and a prescribed threshold valve -VTH is fed to the other input, a peak signal (d) being the result of comparison goes to a logical signal of level '1' when the differential signal (c) reaches the value -VTH or below.

Title: Thermal desorption sample-tube and its sample
Inventor: IMANAKA TSUTOSHI
IPC: G01N30/08
Filed: 1998-05-29
Abstract: PROBLEM TO BE SOLVED: To prevent the deformation or breakage of a thermal desorption sample tube when the tube is connected by reducing the dead volume of the tube with a simple constitution and, at the same time, increasing the strength of the junction by forming a smaller inner diameter section by a prescribed length on the downstream side of the sample heating and expelling section of the tube in the moving direction of samples. SOLUTION: A thermal desorption tube 11 is composed of a sample heating and expelling section 11a which is heated by means of a heat block and non-heating sections 11b and 11c and a smaller inner diameter section 12a is formed throughout the downstream non-heating section 11b. On the other hand, a sealing material 21 having low absorptivity against components to be measured and air permeability is arranged at both ends of a through hole 12 and the space between the sealing material 21 is filled up with a bulky collection-material 22. The inside diameter of the section 12a is made as small as possible within the extent in which a capillary tube can be inserted into the section 12a in a non-contacting state and adjusted to about 1/3 of that of the through hole 12 and the length of the section 12a is made nearly equal to that of the non-heating section 11b.  Since the wall thickness of the section 12a becomes thicker than that of the other part, the strength of the section 12a is increased accordingly. Since the tube 11 has a small surface area, in addition, the sample adsorbing amount of the tube 11 becomes smaller accordingly.
