Title: Scanning probe microscope
Inventor: WARABE TAKESHI
IPC: G05D3/00
Filed: 1995-04-13
Abstract: PURPOSE: To suppress the peak of mechanical resonance of a piezoelectric sufficiently by detecting the increment of current in the vicinity of resonance point thereof in order to protect a probe or the surface of a sample against damage when the probe strikes against the surface of the sample while quickening the response and regulating the voltage being applied to the piezoelectric by feeding the increment thus detected back to the piezoelectric. CONSTITUTION: A probe displacement detecting section 15 detects the displacement of probe in a cantilever 14 and delivers a displacement signal Sz to a Z displacement servo control section 16. The Z displacement servo control section 16 expands/contracts a tubular piezoelectric 13 by applying a Z control voltage Vz. A current (iz) flowing through the tubular piezoelectric 13 is detected by a current sensor 19 and differentiated by a differentiation circuit 20 thus determining an increment of current. A comparator 22 compares a correction voltage ▵V, obtained by amplifying the increment of current through an amplifier circuit 21, with an applying voltage command delivered from the Z displacement servo control section 16 thus producing a voltage Vz being applied actually to the tubular piezoelectric 13.

IPC: G06Q30/02
Filed: 1996-04-10
Abstract: PROBLEM TO BE SOLVED: To provide a system and method for mining a large-sized data base for finding a generalized related rule. SOLUTION: A system and method for finding the purchasing trend of consumers contains a computer executing program for identifying 36 a consumer transacting article set which is stored in a data base, called minimum support, and appears in the data base by the user-defined minimum number The article set contains an article characterized by a hierarchical classifying method. The system finds 38 the related rule of the article section by comparing the number of appearing times of each large article set in the data base with the number of appearing times of the specific partial set of the article set in the data base. When the relation exceeds a prescribed minimum reliability value, the system outputs a generalized related rule indicating the purchasing trend of consumers. An unconcerned rule is discarded from the generalized related rule set 39.  The unconcerned rule means such a related rule that does not occur at a frequency which is significantly different from the frequency expected based on the occurring frequency of the ancestor of the rule.

IPC: G06F15/16
Filed: 1984-05-07
Abstract: PURPOSE:To read the surplus values of circulating code production register CRC of all systems every fixed interval to compare these read values with each other and to detect a discordant system, by using a parallel input/serial output register PS and a register CRC and a control circuit. CONSTITUTION:A computer is actuated and a read/write signal is delivered from a CPU1. The data on a bus 7 is fetched by a PS register 4, and a serial output corresponding to the number of bits of the data are supplied successively to a register CRC5. The bits in a shift register set within the register 5 have the value corresponding to the surplus obtained by dividing the input bit series by a production polynomial G(X). When plural computers are carrying out the same processing, the coincidence is obtained between the data on the bus 7. Thus the coincidence is always secured between the surplus values produced by the polynomial G(X) within the register 5. Therefore the contents of the register 5 are read every fixed cycle and compared with each other to decide whether or not the discordance is produced within the corresponding period.
