Title: Air-fuel ratio control device for internal combustion engine
Inventor: MUTO HIDENOBU
IPC: F02D41/02
Filed: 1997-07-28
Abstract: PROBLEM TO BE SOLVED: To perform proper feedback control of an air-fuel ratio during introduction of purge gas. SOLUTION: Purge of fuel evaporation gas is started from a canister and when purge gas concentration is started to rise, a target air-fuel ratio correction amount λPRG is set to the rich side according to the rise of purge gas concentration and a target air-fuel ratio λTG is corrected to the rich side. Since in a conventional type, even during introduction of purge gas, the target air-fuel ratio λTG is not corrected, during introduction of purge gas, an air fuel ratio of exhaust gas is displaced to the lean side and NOx purification factor is reduced.  To cope with this situation, when, during introduction of purge gas, the target air-fuel ratio λTG is corrected to the rich side according to purge gas concentration, displacement of the target air-fuel ratio to the rich side is cancelled through correction of the target air-fuel ratio λTG to the rich side, an air-fuel ratio of exhaust gas during introduction of purge gas is controllable to a catalyst window and even during introduction of purge gas, a high NOx purification factor is maintained.

Title: Detecting method for flaw in steel material and automatic flaw detector
Inventor: KAMIMURA SHIGENORI
IPC: G01N27/90
Filed: 1981-12-14
Abstract: PURPOSE:To suppress the occurrence of a flaw-detecting unabled region in the proximity of opposite ends of a material to be measured, by a method wherein, when the forward end and the rear end of the material to be measured pass through a position of or in the proximity  of a flaw finding shoe, they are sharply reduced in its a pass speed for a given period of time. CONSTITUTION:If a steel pipe material 1 to be measured is conveyed into a flaw detector 2, the forward end of the mateiral 1 to be measured shields a photoelectric tube 6. This enables a length measuring device 8 to make contact with it, and a measuring length is counted by means of a signal from the photoelectric tube 7. At the point of time when only a distance between the device 8 and flaw-detecting shoes 3, 3' is measured, the shoes 3, 3' are brought into contact with the material 1 to be measured. At this point of time, deceleration of a conveying speed of a conveyor has already been completed to a very slow speed range from a high speed  range. After the very slow speed range is held for a given period of time, an acceleration starts in a similar pattern to that of the deceleration, and it returns back to the high speed range. As described above, in case the forward end and the rear end of the material to be measured pass through the position of or in the proximity of the flaw-detecting shoes so as to match a timing when the flaw detecting shoes make contact with and part from the material to be measured, the conveyor is sharply reduced in its speed for a given period of time, which results in suppressing the occurrence of a flaw-detecting unabled region.

Title: Production of exchange-bonded multilayered magneto-optical recording medium
Inventor: SHIMIZU SHOJI
IPC: G11B11/105
Filed: 1989-08-02
Abstract: PURPOSE:To allow the easy control of the sizes of exchange bonds by depositing incoming particles at the incident angle with a substrate set at a prescribed angle and controlling the sizes of the exchange bonds at the boundaries of the respective layers. CONSTITUTION:The medium constitution of the magneto-optical disk consists in successively forming the films of an intermediate layer 2, the magneto-optical recording layer formed of two-layered films consisting of an alloy film 3 and an alloy film 4, and a protective layer 5 on a supporting substrate 1 by a sputtering method. The positional relation between a target 6 and disk substrate 7 in a sputtering device is so determined that the incident angle theta of the incoming angles with the disk substrate can be set at a suitable value between 0 deg. and 90 deg. on assumption that the sputtering particles come to fly in parallel with the straight line connecting the center of the target and the center of the disk. The sizes of the exchange bonds at the boundaries of the magnetic films can be controlled by changing the incident angle theta of the particles in such a manner. The control of the exchange bonds is possible in this way without inserting control layers.

Title: Nmr signal measuring method of nmr examination apparatus
Inventor: TSUDA MUNETAKA
IPC: G01R33/48
Filed: 1987-08-14
Abstract: PURPOSE:To enhance an NMR signal/noise ratio by reducing the power of heat noise being the main cause of noise corresponding to the reduction in the frequency band contained in an NMR signal, in generating the NMR signal as a gradient echo, by lowering the intensity of the inclined magnetic field due to an inclined magnetic field generating means applied during the measurement of the NMR signal corresponding to the extension of the time from the application time of a 90 deg.-pulse to the generation time of the NMR signal. CONSTITUTION:The frequency band of an NMR signal is proportional to the intensity of an inclined magnetic field and the frequency band of noise corresponds to the frequency band of the NMR signal and the power of noise is proportional to the frequency band of the noise. When a 90 deg.-pulse is applied to an examinee by a high frequency electromagnetic generation means and the time before this echo is generated as the NMR signal is extended, the NMR signal becomes weak and the ratio thereof with noise becomes inferior and, therefore, the intensity of the inclined magnetic field due to an inclined magnetic field generating means applied during the measurement of the NMR signal is lowered corresponding to the extension of said time to reduce the frequency band contained in the NMR signal. Since the frequency band of noise is reduced corresponding to said reduction, the power of noise is also reduced.
