Title: Magnetic head and its production
Inventor: TAKEUCHI HIROSHI
IPC: G11B5/147
Filed: 1986-02-17
Abstract: PURPOSE:To obtain a 'Sendust(R)' magnetic head having a high saturation flux density and high magnetic permeability and excellent high-frequency characteristic by using a laminated composite material formed by alternately laminating and fixing the foil of 'Sendust(R)' obtd. by repetition of rolling with heating rolls and nonmagnetic materials as the core of the magnetic head. CONSTITUTION:'Sendust(R)' has such ductility that the 'Sendust(R)' softens quickly and increases spreadability at 900 deg.C or above. The deformability thereof at 1,100 deg.C is equiv. to the deformability of an aluminum alloy. The 'Sendust(R)' is thoroughly rollable in said temp. region. The 'Sendust(R)' is rolled in said temp. region and a nonmagnetic layer of an oxide film or carbide film is formed on the surface thereof of a nonmagnetic metal or nonmetal is held in place between the rolled materials and again the rolling is repeated, by which the 'Sendust(R)' foil having <=10mum thickness per layer and the nonmagnetic layers are alternately laminated. The respective layers are united to each other by thermocompression bonding and the laminated material is thus obtd. The laminated material is formed to the shape of a core chip by machining such as blanking or chemical etching or laser beam processing by which the core material for magnetic heads made of 'Sendust(R)' is produced with good productivity.

Filed: 1986-02-17
Abstract: PURPOSE:To increase discharge performance by mixing copper oxide and lithium nitrate, and heating the mixture at a temperature exceeding the decomposition temperature of lithium nitrate, then using the mixture as an active material. CONSTITUTION:A mixture of copper oxide and lithium nitrate is heated at a temperature exceeding the decomposition temperature of lithium nitrate, then used as an active material of a positive electrode. By heat treatment, lithium is doped into the copper oxide to form a compound indicated in Li2CuO2, and the Li2CuO2 formed is mixed in the positive electrode mainly comprising copper oxide. When a battery is discharged, Li<+> ions released from Li2CuO2 and react with CuO. Together with this reaction, the reaction of Li in a negative electrode with CuO, with is the main discharge reaction, is advanced. The reaction of Li with CuO is smoothly undergone compared with the absence of Li2 CuO2 in the positive electrode. Therefore, high rate discharge performance is increased.

Title: Image forming device
Inventor: UCHIDA SETSU
IPC: B65H5/02
Filed: 1988-02-17
Abstract: PURPOSE:To preclude an image defect due to the slackening of a beltlike conveying means by specifying the relation between the moving speed of an image carrier and the conveying speed of the conveying means. CONSTITUTION:The driving speeds of respective driving motors are set in rela tion Vd<=Vb, where Vd is the peripheral speed Vd of respective photosensitive drums D1-D4 and the conveying speed Vb of a conveyor belt B. At a transfer position, the conveyor belt B moves faster than the photosensitive drums D1-D4 and the friction driving force by the driving roller 6 is larger than the conveying force by electrostatic attractive force, so force operates on the conveyor belt B in the opposite direction from an arrow P and force operates on the driving roller 6 in the opposite direction from the rotating direction. Therefore, a tension roller 9 does not move and the conveyor belt B does not slackens so much. Consequently, the slackening of the belt B on the driving roller 6 is precluded and an image of high quality is formed.

Title: Automatic lens meter
Inventor: IWANE TORU
IPC: G01M11/02
Filed: 1991-02-27
Abstract: PURPOSE:To easily realize the introduction of a strong light signal and the reduction of the beam diameter of measuring light by guiding the lights from a plurality of uniform light sources to the emitting ends of a plurality of adjacent optical fibers. CONSTITUTION:The lights emitted from a plurality of separately placed light sources 1 are incident on optical fibers 2 from one ends thereof and mixed because they are repeatedly reflected and refracted in these fibers to remove the nonuniformity at the time of the emission from the light sources. Therefore, the optical fibers achieve light scattering function extremely reduced in the loss of the quantity of light and, as a result, a scattering plate is unnecessary and cost is reduced and assembling becomes advantageous. Since the diameter of each of the optical fibers is extremely smaller than that of each of the light source 1, when metal sleeves 3 each having the same diameter as the outer diameter of each of the optical fibers are bonded to the ends of the optical fibers under pressure and bundled as they are to be incorporated in an image forming lens system, the interval between the light sources can be reduced to a large extent and the beam diameter of measuring light can be reduced.

Title: Clutch release bearing device
Inventor: TAKUBO TAKAYASU
IPC: F16D23/14
Filed: 1998-02-16
Abstract: PROBLEM TO BE SOLVED: To prevent muddy water or the like from entering inside a bearing by providing a water discharge passage to be communicated from the inside diameter side of an outer ring of the bearing to the outside diameter side to discharge outside the muddy water or the like entering from a gap between a cylindrical part of a sleeve and an inner ring of the bearing. SOLUTION: A groove 19 in the radial direction formed in a side surface 16 of a flange part 14 of a sleeve 10 constitutes a water discharge groove. The groove 19 is extended in the radial direction and communicates a recessed part 18 with the outside diameter side of the flange 14. The groove 19 crosses in the radial direction the area in contact with an end face of an outer ring 34 among the side surface 16 of the flange 14. Thus, even when muddy water enters the recessed part 18, it is immediately guided to the outside diameter side through the groove 19 as indicated by the arrow. Muddy water or the like guided to the outside diameter side by the groove 19 flows out of a gap between the end of a cylindrical part 42 of a cover 40 and a side plate 20.
