Title: Method for inspecting surface defect of high carbon steel product
Inventor: AZUMA KEIICHI
IPC: G01N27/82
Filed: 1998-11-11
Abstract: PROBLEM TO BE SOLVED: To reduce noise in inspection and to eliminate erroneous detection by adopting either heat treatment of making thin the thickness of decarburized layer on the surface of a steel product or reducing solid solution carbon concentration. SOLUTION: By polishing the surface of a steel product with peeling or the like for eliminating as a non-destructive inspection method with less noise and making thin and uniform the decarburized layer on the surface of the steel product, the generation of noise is relatively reduced and made uniform and the output of a scratched part becomes prominent. Also, by performing heat treatment after rolling, the amount of solid solution carbon in steel can be reduced. When the method is applied to the surface process of a round steel, a surface- polishing process 50 is provided between a soaking process 10 and a heating process 20 and the carbon layer thickness on the surface of the steel product is made thin, thus suppressing noise and preventing erroneous detection.  Also, by providing a spheroidizing annealing process 60 between a rolling process 30 and an inspection process 40 and performing heat treatment under a non-oxidation atmosphere, the boundary between the decarburized layer and a non-decarburized layer on the surface of the steel product becomes broad. Then, a permeability change rate decreases and a magnetic flaw detection noise decreases, thus accurately inspecting a surface detect.

Title: Liquid crystal shutter device
Inventor: FUTAGAWA YOSHIKIYO
IPC: B41J2/445
Filed: 1989-12-11
Abstract: PURPOSE:To miniaturize a liquid crystal shutter device and to improve the reduction of paper consumption and cost by constituting a light source of a heating cathode and a phosphor to which metal is arranged and optimally disposing a liquid crystal microshutter array. CONSTITUTION:The shutter device 10 is constituted of a shutter part 10a and the light source part 10b. Since only the specified polarized light is used for the liquid crystal shutter, transmittance becomes <=50%, therefore, it is required that the brightness of the light source part 10b is twice or more times as much as the sensitivity of a photosensitive body. The luminous efficiency of the phosphor 27 is >=50%, so that in the case that a voltage between the metal 28 for accelerating an electron and the cathode 29 is 100V, the current in the cathode 29 becomes 4mA, and the power consumption in the light source part 10b becomes <=2W. Then, heat can fully radiate from the cubage of constituting elements by this much power consumption, so that the device can be miniaturized without being influenced at all even by making the light source part 10b come into tight contact with the shutter part 10a.

Title: Production of optical recording medium
Inventor: UCHIYAMA KENJI
IPC: G11B7/26
Filed: 1998-10-26
Abstract: PROBLEM TO BE SOLVED: To suppress the adverse effects of initialization treatment on the medium characteristics and to suppress the cost by forming a dielectric layer or reflection layer on an amorphous recording layer and irradiating the layers with charged particles to initialize the recording layer. SOLUTION: In the production of an optical recording medium, layers up to a second dielectric layer 32 are formed, or up to a reflection layer 5, and then the medium is irradiated with charged particles for initialization. The recording layer 4 is formed by a thin film forming method such as sputtering and is in an amorphous state, and is subsequently crystallized when the layer is heated by charged particle irradiation. By irradiation of charged particles in the presence of the second dielectric layer 32 on the recording layer 4, or preferably in the presence of the reflection layer 5 in addition, the recording layer 4 is prevented from etching by charged particles during initialization. Thus, decrease in thickness of the recording layer, or scatter in thickness or film quality of the recording layer are not caused.
