Title: Method and device for undetected failure cause analysis
Inventor: TANAKA KINUKO
IPC: G06F11/26
Filed: 1992-10-27
Abstract: PURPOSE:To enable analyzing undetected failure cause by indicating signal activity state as well as the undetected failure. CONSTITUTION:A signal information output part 1 inputs logical circuit information 4 and test pattern 5, performs failure simulation, and outputs undetected failure information 6 and a signal activity state signal 7. A signal information indication part 2 inputs the information 6 and the signal 7 to search the activity state of the undetected failure signal and indicates signal information indication 8 indicating the activity state regarding the undetected failure signal. An undetected failure cause analysis part 3, basing on the indication 8, judges the cause of undetected failure indication whether the signal regarding the undetected failure is due to unsetting of value for detecting the failure, or due to not transmitted in spite of setting of the value, or due to non-initialization of the logic circuit, and outputs undetected failure cause information 9.

Title: Reproducing method and recording/-reproducing method of optical disk
Inventor: ITO NOBORU
IPC: G11B7/004
Filed: 1998-10-09
Abstract: PROBLEM TO BE SOLVED: To provide a method for reproducing an optical disk capable of suppressing the attenuation of a signal light from a recording layer even if the layer is laminated and used in the surface vertical direction. SOLUTION: A light beam 4 is focused and irradiated on a prescribed recording layer 2a, the temperature of a light beam focused part 6 on this recording layer 2 is raised, and a light beam reflectivity is increased. In the meantime, since the light beam is not focused on other recording layers 2b, the increase in the reflectivity is suppressed. Thus, even in an optical disk where the recording layers and intermediate layers 3 are laminated, the reproduction of information is made possible by the increased reflected light beams from the prescribed recording layer 2a.

IPC: B23Q1/01
Filed: 1995-11-08
Abstract: PROBLEM TO BE SOLVED: To prevent occurrence of damages such as cracks in tables and rails even in a long time service by forming a stone material of a base board whose coefficient of thermal expansion is smaller than that of the stone forming an upper table, a lower table, upper rail groups and lower rail groups.

IPC: H01L21/302
Filed: 1988-11-16
Abstract: PURPOSE:To improve the step coverage of a wiring material made of Al, etc., and to reduce a malfunction such as wire disconnection, etc., by retaining part of a film to be removed at the time of formation of an edge part, and then conducting a reflow process to form a round shape at the edge part. CONSTITUTION:Part of a PBSG film 16 is etched by RIE to form a contact hole 18. In this case, the film 16 is not etched at the whole contact hole corresponding part, but partly retained, and a reflow process is executed in this state. However, since the whole main face of an Si substrate 10 is covered with the film 16, it flows in both directions designated by arrows FB and FC, i.e., not only at its crest side but also at its trough side to form a desirable round shape at the edge part 30. Thus, its step coverage is improved, and the disconnection of a wiring material made of Al, etc., is reduced to improve the reliability of a device.

Title: High-speed sputtering method for ferromagnetic material
Inventor: OKAZAKI KOICHIRO
IPC: C23C14/36
Filed: 1985-12-23
Abstract: PURPOSE:To make continuous and efficient sputtering at a high speed by positioning ferromagnetic materials which act as targets between the N and S poles on one side of a pair of U-shaped magnet bodies facing each other and generating magnetic fields parallel with the targets between the poles on the other sides. CONSTITUTION:The ferromagnetic material 14, 15 which act as the targets are positioned between the N and S poles 10a, 11a, 12a, 13a of the U-shaped magnet bodies 10, 11, 12, 13 which make respective pairs. The magnetic circuit is, therefore, generated in the magnet bodies 10, 11, 12, 13 and the magnetic fields parallel with the targets 14, 15 are generated in the respective poles 10b, 11b, 12b, 13b on the other side. The parallel magnetic fields capture plasma and therefore, if a voltage is impressed to the targets 14, 15 in a vacuum atmosphere, the high density plasma is converged to the peripheries of the targets 14, 15 to bombard the target surface at a high ion density. The targets 14, 15 are thereby sputtered at a high speed and the substrate is efficiently subjected to sputtering of the ferromagnetic materials.

Title: Magnetic head
Inventor: EZAKI JIYOUICHIROU
IPC: G11B5/31
Filed: 1990-10-26
Abstract: PURPOSE:To improve the correspondence for high-density recording and overwriting characteristics by constituting a magnetic film neighboring a conversion gap so that the saturation magnetic flux density of the film is higher than that of another magnetic film, and sharpening the distribution of a magnetic field and the regenerated waveform. CONSTITUTION:Of a magnetic film P11 and a magnetic film P12, the saturation magnetic flux density of the magnetic film P11 neighboring a conversion gap G is higher than that of a the magnetic film P12. A thickness T11 of the magnetic film P11 is thinner than a thickness T12 of the magnetic film P12. As a detailed example, when the magnetic film P12 is formed of NiFe, the magnetic film P11 is formed of CoNbZr. It is suitable that the ratio (T12/T11) between the thicknesses T11 and T12 is located within the range of 1<T12/T11<=25. Namely, of a plurality of the magnetic films P11 and P12, the saturation magnetic flux of the magnetic film P11 neighboring the conversion gap G is higher than that of the other magnetic film P12. Therefore, the magnetic flux is more readily concentrated toward the conversion gap G. Thus, the distribution of the magnetic field and the regenerated waveform are sharpened, and the magnetic field suitable for high-density recording and regeneration is obtained.

Filed: 1997-10-07
Abstract: PROBLEM TO BE SOLVED: To obviate damage to an engine member by installing a binary fluid injection valve, equipped with an inside valve spraying fuel into a combustion chamber from a nozzle hole, and an outside valve, inducing gas in the combustion chamber into a gas passage and blowing out this gas in the gas passage to the combustion chamber, adjacently in the combustion chamber of an engine. SOLUTION: In an exhaust process, an outside valve 29 is opened, making exhaust gas in a combustion chamber 40 flow into a volume part 30 through a gas passage 10 and an exhaust gas pipe 32, and then this outside valve 29 is closed. At a time when a piston 1 goes down from the top dead point, an inlet valve 3 is opened, and air is taken into the combustion chamber 40 by way of an inlet pipe 2. Next, after being entered in a compression stroke, the outside valve 29 is opened, and exhaust gas in the volume part 30 is sprayed into the combustion chamber 40. In succession, the piston 1 is reached to a nearby spot to the top dead point, and at fuel injection timing, an inside valve 24 is opened, spraying the fuel into the combustion chamber 40 from a fuel nozzle hole 14, and thus a flame is generated in this combustion chamber 40.  With this constitution, any possible damage to a constituent member in an inlet system around this combustion chamber 40 due to the exhaust gas is thus obviated.
