Title: Abnormality detecting device
Inventor: FURUSE MITSUYASU
IPC: G01R23/16
Filed: 1999-09-06
Abstract: PROBLEM TO BE SOLVED: To provide an abnormality detecting device which can surely detect the waveform variation of a signal which is unstable due to its period or frequency containing component. SOLUTION: An A/D-converting block 11 finds the sampling data of the waveform of input signals and a high-speed Fourier transformation block 12 finds the frequency spectrum of the input signals from the data row. A memory block 14 temporarily stores the frequency spectrum as the frequency spectrum of a fixed time before. A comparator block 15 compares the frequency from the high-speed Fourier transformation block 12 with the frequency spectrum stored in the memory block 14, and detects the waveform variation of the signals from the differences between the distributions and magnitudes of the spectra. The memory block 13 also temporarily stores a sampling data row during a fixed period and obtains the sampling data rows before and after the comparator block 15 detects signal variation as data for abnormality diagnosis.

Title: Magnetic recording medium and its manufacture
Inventor: SUGITA RIYUUJI
IPC: G11B5/667
Filed: 1983-12-26
Abstract: PURPOSE:To obtain a magnetic recording medium having an excellent recording/ reproducing characteristic by providing a permalloy film where two layers separated by one nonmagnetic layer have different coercive force between a monmagnetic base and a metallic vertical magnetizing film. CONSTITUTION:The permalloy film 4 is formed to the nonmagnetic base 1 and a Co-Cr vertical magnetizing film is formed on the ''Permalloy'' film. The ''Permalloy'' film 4 is separated into two layers, an upper layer 5a and a lower layer 5b by the nonmagnetic layer 6. The ''Permalloy'' film of the two layer film medium is formed as the two-layer structure and the coercive force of the upper layer 5a closets to the Co-Cr vertical magnetizing film 2 is decreased less than the coercive force of the layer 5b closets to the nonmagnetic base 1. Thus, a reproducing signal having more excellent S/N than that of a conventional two-layer medium is obtained in this way.

Title: Air-fuel ratio feedback control device of internal combustion engine
Inventor: HASEGAWA YUSUKE
IPC: F02D41/14
Filed: 1993-09-13
Abstract: PURPOSE:To precisely converge an air-fuel ratio of each cylinder to a target value by serially connecting a feedback control loop to match an air-fuel ratio of an exhaust system collected part with a target value and a feedback control loop to match an air-fuel ratio of each of the cylinders with a target value to each other. CONSTITUTION:Only dispersion among cylinders is absorbed by a feedback corrective term #nKLA for each of the cylinders, and a target air-fuel ratio and deflection are absorbed by a collective part feedback corrective term KLAF. That is, a target value computed by the collective part feedback corrective term KLAF is made a target A/F (air-fuel ratio) and simulatneously, a target value computed by the feedback corrective term #nKLA for each of the cylinders is found by dividing a collective part A/F (air-fuel ratio) by an average value AVE of the feedback corrective term (previously computed value). Consequently, as the collective part A/F (air-fuel ratio) is converged to the target A/F (airfuel ratio), it is possible to converge the air-fuel ratio of all of the cylinders to the target A/F (air-fuel ratio).

Title: Hydraulic booster
Inventor: OKANO KUNIO
IPC: B60T13/12
Filed: 1996-09-24
Abstract: PROBLEM TO BE SOLVED: To surely prevent generation of an abnormal pressure rise in a power chamber, when a power piston is press returned in an operating condition. SOLUTION: When a booster 3 is operated, by a fluid pressure of a power chamber 28, a first check valve 32 is opened, the fluid pressure of the power chamber 28 is accumulated in an emergency accumulator 9 through a passage 42, first check valve 32, passage groove 33a and a passage 35. The hydraulic pressure of the power chamber 28 is accumulated in the emergency accumulator 9 by opening also a second check valve 40. When a power piston of the booster 3 is pushed back, in operation and the hydraulic pressure of the power chamber 28 abnormally rises, the first/second check valves 32, 40 are both opened, the abnormally rising high hydraulic pressure is introduced to a side of the emergency accumulator 9, but the high hydraulic pressure opens a relief valve 44, to be discharged to a reservoir 8. Accordingly, an abnormal rise of the hydraulic pressure in the power chamber 28 is prevented.

Filed: 1989-09-27
Abstract: PURPOSE:To suppress the leakage magnetic field generated by horizontal deflecting coils with a simple structure by inclining respective large-diameter side bend-up sections of a pair of mating saddle type horizontal deflecting coils toward the fluorescent screen side. CONSTITUTION:A pair of mating saddle type horizontal deflecting coils 3 and 4 are fitted on the inside of an insulating frame 1.

Filed: 1990-09-21
Abstract: PURPOSE:To prevent void, the irregularity of density and the peeling of a conductive layer from occurring by specifying the relation of strain recovering time between an elastic layer and a conductive layer in a developing roller. CONSTITUTION:The relation that the strain on the surface of the conductive layer 12c caused by the press-contact with a blade 16 is forcibly pressed back by the elasticity of the elastic layer 12b holds between the strain recovering time of the elastic layer 12b and that of the conductive layer 12c in the developing roller 12. Namely, assuming that the strain recovering time of the layer 12b is Tg(sec) and the strain recovering time of the layer 12c is Tp(sec), the relation of Tp>=Tg is satisfied. Thus, a developing device having a stable function, where the void, the irregularity of density and the peeling of the conductive layer 12c do not occur, is obtained.
