IPC: H01L21/822
Filed: 1991-03-04
Abstract: PURPOSE:To establish the evaluation when writing is performed at any time and to establish the guarantee by performing the reliability test of a memory cell while the writing is performed at any time on the way of test. CONSTITUTION:At first, after a first accelerated test is performed for a blank bit 1, an initial writing is performed to the bit 1 upper in the left side of a block 2 and subsequently, a second accelerated test is performed. Next, a second writing is performed to the bit 1 down in the left side of the block 2, and subsequently, a third accelerated test is performed. Next, a third writing is performed to the bit 1 upper in the right side of the block 2 and subsequently, a fourth accelerated test is performed. A fourth writing is performed to the bit 1 down in the right side of the block 2 and subsequently, a fifth accelerated test is performed and the test is completed. Thus, while an initial retention is guaranteed, after a certain time passes, the writing test is performed, it can be guaranteed that the writing can be performed when the writing is performed or the writing does not cause the retention.

Title: Thin film forming device
Inventor: KITAORI NORIYUKI
IPC: C23C14/30
Filed: 1994-03-08
Abstract: PURPOSE:To form a metallic thin film having a uniform characteristic with a small amt. of power in good yield at the time of vapor-depositing a magnetic material on the surface of a nonmagnetic film in a vacuum vessel to produce a magnetic recording medium by using a field-emission electron beam to heat the magnetic material. CONSTITUTION:A film 3 of polyethylene terephthalate(PET) is rewound from a roll 2a in a vacuum vessel 8, brought into contact with a cooling can roll 1, wound on a roll 2b and traveled. A magnetic material 6 such as Fe, Co and Ni in a crucible 5 is heated by electron beams from an electron gun 7, melted and vaporized, and the vapor is deposited on the part on the roll 1 open to a shielding plate 4 to produce a magnetic recording medium. A cold- cathode field emission electron gun is used as the gun 7 in this case, hence the electron beams are hardly scattered, the scattered beams are not hit on the traveling film 3, and a uniform thin film of the magnetic material is efficiently formed on the substrate film 3 without deteriorating the traveling property of the film 3.

IPC: G11B7/085
Filed: 1997-02-21
Abstract: PROBLEM TO BE SOLVED: To effectively reduce vibration of an objective lens to be generated at the time of moving a slider and to shorten an access time by detecting displacement of a light spot of reflected light at the seek time and performing feedback control on a tracking actuator with a filter-processed output. SOLUTION: A filter processing means has a filter characteristic of reducing or removing a DC component, and is desirable to have a high pass filter characteristic with a low band cut-off frequency which is less than a free vibration frequency of a tracking actuator. At the steady time, the objective lens is controlled in its position by a tracking error signal 10, and at the seek time, a changeover switch 6 is changed by a vibration control suppressing signal 12 to control vibration of the objective lens to be suppressed by a vibration component signal 13. This vibration component signal 13 is obtained by reducing or removing a DC component of an objective lens displacement signal 11 of a photodetector for detecting and outputting in its areas 1a, 1b, 1c and 1d the displacement of the light spot 9 due to vibration of the objective lens by a high pass filter 5.

Title: Bejer curve approximation device
Inventor: SATO YASUHIDE
IPC: G06T11/20
Filed: 1996-01-31
Abstract: PROBLEM TO BE SOLVED: To extremely increase the Bejer curve division processing speed by deciding the end of the division processing according to a fact whether a reference point is included in an area of the prescribed width that is defined by a straight line set parallel to a straight line that connects together the start and end points of a Bejer curve. SOLUTION: When an area decision means decides that a reference point P9 is included in a prescribed area, a y-intercept calculation means calculates a y-intercept (b) of the straight line that is set parallel to a straight line P0 P3 and also passes through the point P9 . Then the area decision means decides whether the y-interception (b) is included in an area C formed between the y-intercepts b1 and b2 . If the y-intercept (b) is not included in the area C, a division end decision means decides that the division operation of a Bejer curve division means is further necessary. If the y-intercept (b) is included in the area C, the division end decision means decides that the point P9 is included in an area having the division decision reference value H0 based on the line P0 P3 and discontinues the subsequent division processing of the Bejer curve division means.

Title: Production of metal uranium
Inventor: TERAMAE NAOKI
IPC: C25C3/34
Filed: 1996-02-26
Abstract: PROBLEM TO BE SOLVED: To provide such a production method of metal uranium that the produced metal uranium is not contaminated with the source material, the metal uranium dose not react again with a fused salt of fluoride and a higher recovery rate and current efficiency can be obtd. than a conventional method. SOLUTION: In an electrolytic cell 10 equipped with a container 14 below a cathode 11 in the cell, uranium oxide in a fused salt of fluoride 15 is reduced by electrolysis at a temp. higher than the melting point of metal uranium 13 to precipitate metal uranium 13 on the surface of the cathode 11. The precipitated metal uranium 13 is made to drop due to the difference in the specific gravity from the fused salt and corrected in the container 14. In this method, before the electrolytic reduction, a metal oxide is supplied together with the uranium oxide in the electrolytic cell 10 so that the metal oxide produces such a metal 20 that has smaller specific gravity than the metal uranium and does not form an alloy with the metal uranium or hardly form an alloy in the electrolytic reduction process.  The metal uranium phase A is covered with a light metal phase B so that the uranium phase A is not in contact with the fused salt phase C or the raw material uranium oxide.

Title: Fixing device and image forming device provided with the same
Inventor: OTSUKA YASUMASA
IPC: G03G21/00
Filed: 1999-02-16
Abstract: PROBLEM TO BE SOLVED: To prevent deterioration in picture quality due to dirt on a pressure roller over a long term. SOLUTION: The temp. rising rate ΔT/Δt is calculated at every 100 msec based on a detection temp. of a thermistor. This is compared with the temp. rising rate (a) measured beforehand by a 100 V input (S4), and when the ΔT/Δt is smaller than (a), the wavenumber or the phase angle of an input control is changed, and power is increased (S5). On the other hand, when the ΔT/Δt exceeds (a) in S4, the wavenumber or the phase angle of the input control is changed, and the power is reduced (S6). Thereafter, until the ΔT/Δt becomes (a) or below (S7), the power reduction (S6) is repeated, and when the ΔT/Δt becomes (a) or below, the increase/decrease in the power is adjusted, and when a count t of a timer exceeds t' (S8), and the input control is changed to the control at a first control temp. T1.  Thus, since a temp. difference between a fixing film and the pressure roller is reduced, the dirt transferred from the fixing film to the pressure roller is prevented.

Filed: 1987-02-20
Abstract: PURPOSE:To prevent the fall of an S/N, due to a low sensitivity diode by omitting the output of the low sensitivity diode, and performing a time delay integration (TDI) processing. CONSTITUTION:At the time when the outputs of plural number (e.g., three number) of photoelectric conversion diodes 1 are summed up together, the output of the diode 1-1 of a first stage is made to pass through two steps of a delay circuit 6, and the output of the diode 1-2 of second stage is made to pass through one step of the delay circuit 6, but the outputs of the respective diodes 1 are supplied to a following stage through a cutoff means 200, e.g., a gate circuit. By using the cutoff means 200 like the gate circuit, if the diode, the sensitivity of which is lower than a prescribed value, exists, the output of the said diode is prevented from being transmitted by making the corresponding cutoff means 200 operate, and by using only the outputs of the remaining diodes, the TDI processing is performed. Thus, the deterioration of the S/N can be prevented.
