Title: Magnetic disk evaluating device
Inventor: TAMURA FUMITAKA
IPC: G11B5/84
Filed: 1990-02-05
Abstract: PURPOSE:To shorten the measurement time for evaluating the durability of a magnetic disk by disposing plural pieces of magnetic heads on the same circumference of the magnetic disk, thereby increasing the total sliding length of the magnetic heads with respect to the magnetic disk. CONSTITUTION:Magnetic disk evaluating bodies 1-1 to 1-4 are disposed on the same circumference of the magnetic disk 6 and have magnetic head parts 8 and detecting parts 2. The respective magnetic heads 81 are simultaneously slid on the disk 6 and the sliding friction forces at 4 points are measured during one rotation. The total sliding length of the heads 81 with respect to the disk 6 is, therefore, increased. The rotating speed of the magnetic disk in a contact start and stop test decreases to 1/4 if the number of the heads is 4. The measurement time in the case of the measurement accuracy maintained at the same level is shortened in this way.

Title: Simultaneous measurement of hippuric acid and mandelic acid
Inventor: OKADA EIJI
IPC: G01N30/88
Filed: 1987-02-06
Abstract: PURPOSE:To simultaneously measure hippuric acid and mandelic acid without requiring pretreatment, by using a specific ion pair forming agent as a mobile phase and using a reversed-phase column as a fixed phase. CONSTITUTION:A reversed-phase column 1 is packed with a fixed bed wherein an octadecyl group or an octyl group is chemically bonded to the surface of a silica particle: one end thereof is connected to a mobile phase tank 3 through a specimen injection port 2 and the other end thereof is connected to an ultraviolet absorptiometric detector 4. A mobile phase containing at least 0.5mmol. of an ion pair forming agent (e.g., a solution prepared by adding 10% of acetonitrile to a buffer solution obtained by dissolving 1mmol. of hexasulfonic acid and 5mmol. of sodium dihydrogen phosphate in 1l of water and adjusted to pH3.00) is received in the tank 3. By this constitution, since the basic functional group of hippuric acid in a specimen selectively forms the ion bond with hexasulfonic acid in the mobile phase, the time up to dilution of the hippuric acid is extended as compared with mandelic acid and both components flow in the detector 4 so as to provide a time interval and respectively detected as independent peaks.

Title: Image forming method
Inventor: KIMURA MASATOSHI
IPC: G03G15/00
Filed: 1986-02-09
Abstract: PURPOSE:To reduce the size of an image forming device by sticking elec trostatically charged toner approximately uniformly to the surface of a photosen sitive layer by a developing machine at the 1st rotation of a photosensitive body, exposing the toner surface by an image exposing means and applying electric potential having reverse polarity against the electrostatic charge of the charged toner by the developing machine at the 2nd rotation. CONSTITUTION:Simultaneously with approximately uniform toner development on the photosensitive layer 1c by the developing machine 2 or after the toner development at the 1st cycle of the photosensitive body obtained by laminating the photosensitive layer 1c on a transparent or translucent conductive film 1b, image exposure is executed by an LED array optical system 5 from the transparent substrate (a) side. At the 2nd cycle, a reverse bias voltage 9 is impressed to the developing machine 2 by a switch 20 to obtain a toner image by electrostatically removing toner sticking to the nonimage exposing part at the 1st cycle. The toner image is displayed as a still image and transferred to recording paper 10 or the like. Since continuous toner images can be obtained by repeating said two cycles, the size of the image forming device can be reduced.

IPC: B41J2/45
Filed: 1999-02-03
Abstract: PROBLEM TO BE SOLVED: To inexpensively and accurately correct a main scanning magnification by providing a transverse chromatic aberration compensation means for compensating the deviation of an image-formation position in a main scanning direction on a photoreceptor caused by the difference or the fluctuation of the wavelength of a light beam in a scanner optical system. SOLUTION: A toric lens 36 is arranged on a polygon mirror side and a composite optical device 37 is arranged on the side of a surface to be scanned. As for the device 37, its surface on an incident side is constituted of an aspherical surface (plane in a subscanning direction) having power only in a main scanning direction and the surface on an emitting side is constituted of a surface where a diffraction grating is added to the plane. A beam emitted from the device 37 scans to form an image on the surface to be scanned (photoreceptor) 38. The power arrangement of the lens 36 and the device 37 is decided so as to compensate the change of the image-formation position in the main scanning direction caused by the difference of the wavelength or the change of the wavelength of the beam.  Namely, the transverse chromatic aberration of a scanning optical system is compensated by a refraction element 36 having positive dispersion in the main scanning direction and a diffraction element 37 having negative dispersion therein.

Inventor: SAKAMOTO MASAHIRO
IPC: H04N1/401
Filed: 1985-02-15
Abstract: PURPOSE:To attain picture conversion with high reliability based on a proper slice level independently of the distribution of original reflectances by providing a holding means for holding an electric quantity corresponding to a maximum value of the reflectance of an original picture and making the level of the reproduced output variable in response to the electric quantity. CONSTITUTION:In scanning a white reference face for distortion correction, an output signal as the result of scanning the reference face similarly as a conventional device is converted into a digital value by an A/D converter 9 and stored in a memory 7. Similarly in case of original scanning, the slice level is decided by a variable resistor 15 based on the signal corresponding to the distortion reproduced via a D/A converter 11 from the memory 7 to apply binary-coding of a picture signal. In reproducing the distortion signal by the D/A converter 11, a signal 11a corresponding to a potential across a capacitor 23 is used and a resistor 25 taking the time constant sufficiently is used as a reference value of the D/A converter. That is, even when a part having the maximum reflectance exists in any part of the original, the brightness signal of the part is stored in the capacitor 23 and the slice level is decided by the D/A converter 11 based on the voltage.
