Title: Method of cleaving wafer of semiconductor laser
Inventor: NOJIRI HIDEAKI
IPC: H01L21/301
Filed: 1988-11-09
Abstract: PURPOSE:To improve production yield of an element by allowing a wafer to be brought into contact with a member for cleaving the wafer locally for cleaving the wafer. CONSTITUTION:A wafer 1 is cleaved by allowing the wafer 1 to contact a member 15 for cleaving the wafer 1 locally. Namely, since cleavage is performed so that load is applied centrally at one point of scribing trace on the wafer 1, only a single point may be made per one scribing trace for enabling alignment to be easy and achieving an accurate pitch machining, thus reducing frequency for this wafer to be crushed and improving production yield of elements.

Title: Roll stain detector in locking printer
Inventor: UEDA YOSHIO
IPC: B41F17/36
Filed: 1985-12-13
Abstract: PURPOSE:To automatically and ensurely detect a stain on the surface of a roll rotating at a high speed and to obtain a signal processing circuit of comparatively simple constitution and a whole device of relatively low cost, by a method wherein a reflection type photodetector detects a change in reflectance to detect the stain. CONSTITUTION:In a locking printer, each part and a cleaning device are controlled according to an output signal from a stain detector provided with a reflection photodetector 17 and a signal processing circuit 19. For example, in the presence of an ink stain on a transfer roll, the ink stain causes a drift of base electric potential in an output signal of the photodetector 17, i.e. an output signal of an amplifier 26. The drift is eliminated by a band-pass filter 27 in a first abnormal signal detect circuit 24, thus resulting in a high detecting accuracy, on the other hand, in the presence of an ink stain on a transferred surface from the transfer roll, and output signal from a low-pass filter 32 in a second abnormal signal detect circuit 25 is varied immediately after a printing is started to generate a drift of base electric potential according to the stain. With the drift larger than the criterion value, an output circuit 35 outputs a stain detect signal for a fixed time.

Title: Production of porous ceramic
Inventor: MIYAGAWA NAOMICHI
IPC: C04B38/04
Filed: 1997-10-15
Abstract: PROBLEM TO BE SOLVED: To obtain a porous body of a desired porosity that has oriented uniform through-holes by allowing a metal magnetic fiber material to be oriented on the surface of a porous base material in a magnetic field, coating the resultant porous body with a ceramic material-containing slurry and drying them to solidness. SOLUTION: Nickel, iron or cobalt is used as the metal magnetic fiber material. The porous base material is, for example, gypsum board or porous alumina base plate. The slurry comprises a ceramic powder and a solvent and the powder is alumina with an average particle size of <=10 μm. In order to orienting the metal fibers, a porous base plate is allowed to stand still in the stationary magnetic field and the metal fibers are allowed to fall on the porous based plate. Then, the slurry containing ceramic is cast and dried to solidification. The solidified product is heat-treated (800-1,000 deg.C in the case of nickel or alumina), treated with an acid as hydrochloric acid at 90-100 deg.C to leach out the metal fibers. Finally, the resultant product is heat treated again to give the objective porous body with a porosity of 5-60%.

Filed: 1996-10-24
Abstract: PROBLEM TO BE SOLVED: To enable sufficient braking force to be attained even if a rotating speed of a rotator is low, provide a simple structure, less amount of trouble and reduce manufacturing cost. SOLUTION: A hub section 6B of a rotator 6 is fitted to and inserted into a twist coil spring 13 in which its one end is fixed to a fixed shaft 2 and the other end is fixed to a spring holder 14. As a centrifugal weigh 7 rotated together with the rotator 6 is displaced toward an outer radial side by a centrifugal force, a clutch member 12 rotated together with the rotary member 6 in cooperation with the displacement is displaced and press contacted with the spring holder 14. As the spring holder 14 is rotated under the press contacted state o the clutch member 12 to cause the twist coil spring 13 to be twisted, its inner diameter is reduced and the hub section 6B is fastened to apply a braking to the rotator 6.

Title: Magnetic recording medium
Inventor: SHINOHARA KOICHI
IPC: G11B5/706
Filed: 1987-11-10
Abstract: PURPOSE:To improve a C/N characteristic by specifying the packing factor of a perpendicularly magnetized film consisting of a Co alloy to <=0.75 and disposing a thin hard-carbon film as a protective film. CONSTITUTION:The packing factor of the perpendicularly magnetized film 2 consisting of the Co base alloy is <=0.75 and the thin hard-carbon film is disposed as the protective film 3. Gaps are thereby generated between fine columnar particles 2 consisting of the Co base alloy, by which magnetical sepn. is improved and noises are decreased. The thin hard-carbon film which is the protective film 3 is anchored into the gaps between the fine particles 2 and since the adhesive strength is thereby increased, the film is formable to the smaller thickness and, therefore, the spacing loss is decreased and the larger output is obtd. The C/N is thus greatly improved.
