Title: Bit error processing method of storage device
Inventor: NAKADA KOUZOU
IPC: G06F12/16
Filed: 1982-11-30
Abstract: PURPOSE:To discriminate suitably if a bit error comes into an important fault by checking whether or not there exists an error in the same bit of prescribed other addresses as a bit having the error in detecting a bit error in an address. CONSTITUTION:When a bit error is detected as to an address N1 of a memory 1 by an error check controller 2 and the bit number is >=2-bit, an alarm signal is raised and the processing is finished. When the bit number is (1), whether or not there exits the bit error as to addresses other than the address N1 is checked. When no error is detected, the error bit of the address N1 is corrected for itself. When the error is detected, whether or not the error bit is the same as that of the address N1 is discriminated. When the same, since it is highly possible that the error is an important fault, an alarm signal is generated. When not the same, the error is corrected by itself and the error processing is finished.

Title: Dressing device, polishing device, and polishing method
Inventor: HIGUCHI KATSUTOSHI
IPC: B24B53/017
Filed: 1999-07-23
Abstract: PROBLEM TO BE SOLVED: To allow a good dressing of a polishing cloth for a long time by providing a dressing tool with a structure where many cubic-system nitride elementary particles are fixed to a base material. SOLUTION: A dressing tool 2 is rotated counterclockwise by a driving shaft 4. At this time, many cubic-system nitride elementary particles 6 on the lower surface of the dressing tool 2 come into contact with a polishing cloth 12 under pressurization to remove polishing chips embedded in micro recessed and projecting parts of the polishing cloth 12 and to polish the surface of the polishing cloth for dressing. Because the cubic-system boron nitride(cBN) particles 6 have good abrasion resistance under a high temperature, the cBN particles 6 do not wear to provide a good dressing performance over a long time even when the cBN particles 6 are exposed to the high temperature due to frictional heat during the dressing of the polishing cloth 12.  Therefore, the dressing of the polishing cloth 12 combined in a polishing device with a lowered polishing performance can be performed well over a long time.

Title: Controller for electric vehicle
Inventor: NUMAZAKI MITSUHIRO
IPC: B60L9/18
Filed: 1989-08-16
Abstract: PURPOSE:To suppress idling and slip without increasing torque of other shafts by stopping or suppressing current control of each motor upon occurrence of idling or slip on one of a plurality of drive shafts. CONSTITUTION:Signals are fed from rotation detectors 8a, 8b,... for respective motors to rotation operating units 10a, 10b,..., and operated rotations are fed to a comparator 11. The comparator 11 compares the rotations and if any one rotation is remarkably higher than other rotations, the drive shaft corresponding to the remarkably high rotation is judged to be an idling shaft and an idling detection signal is produced. Since slip frequency is maintained constant during idling of drive shaft, current of other motors compensates for the current droppage of the idling motor and maintained constant and thereby the possibility of causing idling of other drive shaft can be lowered.

Title: Continuously generating method for large-output soft x-ray
Inventor: ARATA YOSHIAKI
IPC: H01J35/22
Filed: 1986-09-06
Abstract: PURPOSE:To prevent the reduction of the radiation efficiency of soft X-rays and continuously radiate constant large-output soft X-rays or large-capacity plasma radiated light by stopping the abrupt decrease of the plasma density while electromagnetic waves are being applied via the gas feed control such as the high-speed gas puff injecting method. CONSTITUTION:A fixed quantity of gas is fed using a gas bomb 1 and a needle valve 2, and its pressure is measured by the ion gauge of a vacuum indicator 5. When the pressure is abruptly decreased, of course the signal of the vacuum indicator is decreased. Then, a signal corresponding to the initial pressure is applied as a reference signal 6, both signals are fed into a comparator 7, the difference signal is extracted and fed to an amplifier 8, and the output is applied to a high-speed gas puff valve 4. When a piezo element is operated and the valve is opened, the gas accumulated in a gas reservoir 3 from the gas bomb 1 in advance is momentarily fed into a container of a plasma generating system at a high speed to compensate the reduction of the pressure. Accordingly, plasma density is maintained constant, thereby the radiation efficiency of large-output soft X-rays generated can be maintained constant.

Title: Optical disk device
Inventor: KATAYAMA TAKESHI
IPC: G11B7/095
Filed: 1994-09-05
Abstract: PURPOSE: To improve follow-up ability by applying a repetitive learning control theory to tracking control and focus control. CONSTITUTION: A shape of disk eccentricity of one before is stored in a learning memory 1, and the fact what the shape of the disk eccentricity of one before of the present eccentricity is changed is calculated. By passing the calculated result through an LPF 3 via an absolute value ALU 2, a mean value of track correlative amounts by several to scores of tracks is calculated. Then, a gain of a tracking control system is increased using a variable gain compensation part 4 based on the calculated correlative amount when track correlation is strong. Further, the gain of the tracking control system is decreased using the compensation part 4 when the track correlation is weak. Thus, a loop gain is decreased when the track correlation is broken due to sudden disturbance such as vibration in on-vehicle, etc., and a scratch, etc., of a disk, and a control system is stabilized.

Title: Search system for state space
Inventor: KOJIMA YASUHIRO
IPC: G06N5/04
Filed: 1995-08-21
Abstract: PROBLEM TO BE SOLVED: To reduce the required storage capacity by providing the high-quality solution on the early stage of search by deciding the transient destination of current state by evaluating the adjacent state of state space corresponding to the sum of a state change cost function value and the evaluation function value of the adjacent state. SOLUTION: The state to be the start point of state space search is initially set to the current state (concerned state) and its evaluation function value is calculated (1). Afterwards, the states transitable from the current state are extracted and their evaluation function values are respectively calculated (4). When any state requiring the change of its evaluation function value exists among the extracted states, that evaluation function value is changed (5). Further, the adjacent extracted state is evaluated corresponding to the sum between the total sum of values of elements of state change cost function value vectors corresponding to the elements having difference between that state and the current state and the evaluation function value of the adjacent state and the state having the smallest evaluation function value is selected as the best adjacent state (the next concerned state) (6). Thus, the adjacent state is evaluated so that the transient destination of current state can be decided.
