Patent JP-H11175988-A (JP)
Title: Optical head device
Inventor: KANEKO MOTONORI
IPC: G11B7/09
Filed: 1997-12-09
Abstract: PROBLEM TO BE SOLVED: To reduce the adverse effect of external disturbances on focus control caused by noncoincidence between one dividing line for dividing a light receiving area for focus error detection of a photodetector because of the limitation of optical arrangement and the different direction of the intensity distribution of a light beam generated by the effect of external disturbances by a signal track. SOLUTION: One dividing line 18 for dividing a light receiving area is set in a direction shifted in the tangential direction PT-PT' of a signal track by π/4(rad) from an astigmatism generating direction PB-PB' on a light receiving area 17. Thus, without narrowing the width of a disk in a diameter direction in the outer dimension of an optical head device, the effect of external disturbances caused by a signal track generated in a focus error signal is reduced.

Title: Structure of stator for ultra high speed brushless motor and fabrication thereof
Inventor: TAKAHASHI KATSUMI
IPC: H02K1/12
Filed: 1990-11-30
Abstract: PURPOSE:To suppress heating of stator and to realize simple and inexpensive fabrication by employing a double-structured cylindrical stator comprising a stator core composed of magnetic material having low iron loss and another stator yoke composed of magnetic material having excellent saturation magnetic flux density disposed on the outside. CONSTITUTION:A stator secured onto the inner face of a motor casing 1 comprises a cylindrical pure iron stator yoke 2 forming a magnetic path only under heavy load, a cylindrical ferrite stator core 3 disposed on the inside and thick enough to form a magnetic path of rotating field under light load, and a coil 4 secured to the inside thereof. Since the rotating field is relatively weak under light load, only the stator core 3 forms a magnetic path thus suppressing heating. Under heavy load, both the stator core and the stator yoke 2 form magnetic paths to prevent flux leakage so as to enhance motor efficiency. According to the constitution, the stator yoke 2 and the stator core 3 can be integrated in the fabrication resulting in cost reduction.

Title: Blind slats and manufacture thereof
Inventor: SAWAMURA ATSUYA
IPC: D04H1/60
Filed: 1993-12-06
Abstract: PURPOSE:To manufacture blind slats easily, and at a low cost and provide excellent ventilation properties, and to modulate lighting delicately, and take in a soft lighting. CONSTITUTION:There is prepared paper 6 (60g/m<2>) which includes 30 to 100% hot-melt fiber, such as low-molten polyester at a temperature around 110 deg.C. The paper 6 is slit-processed, thereby producing a roll whose width is slightly smaller than that of a blind slat. An extruder 1 is used to extrude carbonated resin 8 with a base 2 of the extruder 1 in such a fashion that it may be flatly shaped. After extruded, the paper 6 is contact-bonded with a roller 4 on a single surface of the resin 8 at a temperature around 200 deg.C. During the contact bonding, the low molten polyester resin is molten with the heat of the resin 8 and bonded to the resin 8. The resin 8 whose temperature exceeds about 150 deg.C is formed with a pair of molding dies 5 so that they may be curved in their cross section and then the molded resin is cut in specified length to prepare a slat.

Title: Green nacreous pigment
Inventor: KAWAKAMI TORU
IPC: C09C1/40
Filed: 1993-12-08
Abstract: PURPOSE:To obtain a green nacreous pigment having brilliancy and a more intense hue by coating mica flakes with a titanium dioxide layer and coating the titanium dioxide layer with a compound oxide layer comprising specified metal oxides. CONSTITUTION:This pigment is prepared by coating mica flakes with a titanium dioxide layer and coating the titanium dioxide layer with a compound metal oxide layer comprising cobalt oxide, nickel oxide and zinc oxide. An example of the process for producing this pigment comprises adding a titanium compound solution (e.g. titanium tetrachloride solution) to a preheated white mica suspension, hydrolyzing the titanium salt to precipitate a hydroxide or oxide of titanium on the white mica flakes, washing the coated mica slurry with water, filtering the slurry, heat-treating the obtained cake, and coating the heated- treated cake with the above compound oxide. Thus, the pigment retaining high brilliancy inherent in titanium dioxide, having a more intense hue and being various in color can be obtained.

Title: Disk-shaped recording medium and disk unit using the same
Inventor: YAMAMOTO NORIYUKI
IPC: G11B20/12
Filed: 1997-12-10
Abstract: PROBLEM TO BE SOLVED: To miniaturize a sector pulse generation table without largely deteriorating the format efficiency, and reduce the time required for address conversion processing. SOLUTION: A disk has a servo area for recording servo information in each of a plurality of segments in the rotational direction, and a data area for recording user data. The segment and the logical sector do not correspond to each other on the one-to-one basis. The data area of each segment is divided into a plurality of uniform virtual segments, and each sector is aligned with a virtual segment. The virtual segment is a theoretical segment. To generate a sector pulse, it suffices to have a table having information of the number of bytes per virtual segment and the number of virtual segments per sector. In comparison with the case where the sector is aligned with the segment, reduction in the format efficiency can be restrained. Conversion between the sector number and the segment number, that is, arithmetic processing of the address can be carried out in a short time.
