Title: Optical magnetic recording disk
Inventor: ORUKAWA MASAHIRO
IPC: G11B11/10
Filed: 1986-11-13
Abstract: PURPOSE:To improve a S/N in an inner peripheral part and to increase a storage capacity without deteriorating a recording sensitivity in an outer peripheral part by laminating in order of a protective film, a magnetic body film and a thermal diffusion film on a substrate, and reducing the film thickness of the thermal diffusion film from the inner peripheral part to the outer peripheral part. CONSTITUTION:A magnetic thin film 3 is laminated on the substrate 1 formed by plastic through a protective layer 2, and furthermore, the thermal diffusion film 5 whose film thickness decreases from the inner part to the outer part of the disk is formed through a dielectric 4. The optical magnetic disk has a diameter of 130mmphi, and a radius from 30mm to 60mm is used for recording and reproduction. The film thickness of the thermal diffusion film 5 in the inmost peripheral part is 500Angstrom , and below 50Angstrom  in an outermost peripheral part. Thus, the S/N in the inner peripheral part can be improved by about 2dB over, and a shortest domain length can be shortened from mum to 0.8mum, whereby the storage capacity per disk can be increased by 25%.

Title: Surface layer defect detector
Inventor: HIRONO AYUMI
IPC: G01N21/88
Filed: 1991-10-18
Abstract: PURPOSE:To enable the detection of a defect in a surface layer easily at a high accuracy with a simple light source device by using a band-like white diffusive light with a uniform quantity of light distribution. CONSTITUTION:A band-shaped white diffusive light of a fluorescent lamp 16 is applied to the surface of an object 1 to be inspected. A line sensor S having a number of photodetectors is set on a boundary line part with a photodetecting field of view thereof extending in the longitudinal direction of the band-shaped light on the surface of the object 1 to be inspected. In this case, the existence of irregularities on the boundary line part on the surface of the surface layer 3 or the peeling of the surface layer 3 so much as to expose a substrate 2 as defect are detected as defect signal of the sensor S. In the case of an object 1 to be inspected having a light transmitting surface layer 3, the photodetecting field of view of the sensor S is set on the center line in the longitudinal direction of the band-shaped light on the surface of the object 1 to be inspected. As a result, a change in a thickness of a light transmitting layer (for, example, charge generation layer 5 and charge transport layer 6) of the surface layer 3 and the presence of impurities in the layer are detected as defect detection signal of the sensor S. The boundary line part of the photodetecting field of view of the sensor S and the setting of the center line position can be selected.

Title: Feed for adult chicken
Inventor: KUROSE YASUHIRO
IPC: A23K1/18
Filed: 1987-10-29
Abstract: PURPOSE:To prevent soft feces of adult chickens and contrive improvement in egg quality and enrichment of nutrient ingredients, by blending maize residues as a cereal ingredient of a feed for adult chicken with other ingredients. CONSTITUTION:Grains separated from corncobs are pulverized and sieved to produce a maize. In the process, maize residues left on a sieve are recovered. Thereby the maize residues which have hitherto been mostly discarded are effectively utilized and used as a cereal ingredient of a feed for adult chickens to produce the aimed feed. Since the maize residues contain more crude fats, crude fibers, vitamins, minerals and linoleic acid than those of maize, the residues are useful as the feed ingredient. Furthermore, the maize residues are preferably used in a state of rather coarse particles. Thereby habit of selecting and eating grains by chicken can be utilized. Since the embryo bud parts are present sticking to the base parts, chickens are attracted by palatability of the embryo buds, resulting in eating of also the basal part.

Filed: 1990-10-12
Abstract: PURPOSE: To enable a sufficient tightening effect by a small screw-tightening motion in a screwing cap by providing tightening sleeves between a screwing head part and the screwing cap, and by tightening the screw-tightening cap so that these tightening sleeves are moved toward both sides by the mutally sloped surfaces being in contact with these tightening sleeves so as to be pressed against to each other. CONSTITUTION: To tighten a fitted tool in a desired operating position, two tightening-sleevs 10 are fitted as a tightening mechanism between a screwing head part 2 and a screwing cap 3. Since the hole 11 of these tightening-sleeves 10 has a diameter slightly larger than that of the tool shaft, these sleeves can move toward both sides with a play. When the screwing cap 3 is loosened, the tool is pushed away in a desired position, and then the screwing cap is screwedly tightened. Thereby, the sloped surfaces 15, 16 of the tightening sleeves 10 are pressed against each other, and are moved toward the reverse direction in both sides thereof, so that the holes of the tightening sleeves are pressed against the tool shaft, thus the tool shaft is tightened.
