摘要： A mechanism for computing the basic ignition period of a spark plug from engine running conditions, a mechanism for judging whether or not the running conditions are within a delay correction region, and a mechanism for computing a basic delay amount if the running conditions are within the delay correction region, are provided. The accelerator opening or throttle opening are detected, and after the delay amount has been corrected according to the detected opening, the basic ignition period is corrected by the basic delay amount. The spark plug thereby ignites the fuel with the corrected ignition period, and the engine catalyst is activated early without impairing engine running performance after engine start-up.

摘要： An engine provided with a purge valve introducing fuel vapor from the fuel tank into the intake passage, a purge valve for opening and closing the passage, a device for setting a basic flowrate of the purge valve according to the engine running conditions, and a device for detecting the fuel concentration of the purge gas. Further, a device is provided for correcting the basic flowrate based on the fuel concentration of the purge gas so as to decrease the purge valve flowrate when the fuel concentration is high, and increase the purge valve flowrate when it is low. The purge valve opening is controlled according to this corrected flowrate, and purging can therefore be performed rapidly without adversely affecting the air-fuel ratio.

摘要： A magneto-optical disk having a magnetic layer and a conductive layer laminated on a transparent substrate, and having a lubricant layer provided on the conductive layer. Recording and reproduction on and from the magneto-optical disk are performed by a flying head. The flying head glides above and lands on the lubricant layer. The magneto-optical disk can therefore be removed from the device easily since a magnetic head does not adhere to a recording medium. Further, a depressing force exerted on the flying head is controlled so as to maintain a constant floating gap between the flying head and the recording medium. The depressing force is controlled by electrostatic capacity between an electrode, provided on a bottom face of the flying head, and the conductive layer. Consequently, highly reliable recordings can be made since a magnetic field intensity applied to the magnetic layer becomes constant. It is desirable that the lubricant layer be composed of an organic binder containing a powder belonging to the ethylene tetrafluoride resin family.
摘要翻译：一种磁光盘，其具有层叠在透明基板上的磁性层和导电层，并且具有设置在导电层上的润滑层。在磁光盘上进行记录和再现由飞头执行。飞头在上方滑动并落在润滑剂层上。因此，由于磁头不粘附到记录介质上，因此可以容易地从设备中移除磁光盘。此外，控制施加在飞头上的压下力，以便在飞头和记录介质之间保持恒定的浮动间隙。抑制力由设置在飞头的底面上的电极与导电层之间的静电电容控制。因此，由于施加到磁性层的磁场强度变得恒定，所以可以进行高度可靠的记录。希望润滑剂层由含有属于四氟乙烯系树脂的粉末的有机粘合剂构成。

摘要： A magneto-optical recording method includes the steps of applying an external magnetic field perpendicularly onto the magnetic thin film with perpendicular magnetization of a magneto-optical recording medium and projecting a light beam onto the magneto-optical recording medium; and modulating the intensity of the light beam between the first light intensity and the second light intensity in response to the information to be recorded while shifting a spot of the light beam, thereby recording information. In the above method, the first light intensity is set such that by reducing the coercive force of the magnetic thin film with perpendicular magnetization, a magnetic domain is formed on the magnetic thin film with perpendicular magnetization, and that the magnetic domain is moved as the spot of the light beam is shifted. The second light intensity is set such that by increasing the coercive force of the magnetic thin film with perpendicular magnetization, the magnetic domain is fixed to the position.

摘要： A magneto-optical recording device has a flying head that floats over a magneto-optical disk according to the rotation of the magneto-optical disk. The flying head includes a head slider. A solid lubricant is applied to the bottom surface of the head slider facing the magneto-optical disk. Since the solid lubricant makes the flying head contact with the magneto-optical disk smoothly, the scratching and wear of the magneto-optical disk and the flying head decrease. Therefore, the reliability and the durability of the magneto-optical recording device can improve. Physical protrusions and recessions or holes containing fluorocarbon oil therein may be formed instead of the solid lubricant. In this case, the contact area between the flying head and the magneto-optical disk is also smaller than the case where physical protrusions and recessions are not formed. In addition, with a configuration such that thin-film layers made of a fluorocarbon resin having an excellent lubricity are formed on both sides of the bottom surface of the head slider, since the magneto-optical disk comes into contact with the head smoothly, the reliability and the durability of the magneto-optical recording device can improve.
摘要翻译：磁光记录装置具有根据磁光盘的旋转而浮动在磁光盘上的飞头。飞头包括头滑块。将固体润滑剂施加到面向磁光盘的磁头滑块的底表面上。由于固体润滑剂使飞头与磁光盘平滑地接触，所以磁光盘和飞头的划伤和磨损减小。因此，可以提高磁光记录装置的可靠性和耐久性。可以形成其中包含氟碳油的物理突起和凹陷或孔，而不是固体润滑剂。在这种情况下，飞头和磁光盘之间的接触面积也小于没有形成物理突起和凹陷的情况。此外，由于磁头与磁头滑块底面的两侧形成具有优异的润滑性的氟碳树脂制成的薄膜层，所以由于磁光盘顺利地与磁头接触，所以，可以提高磁光记录装置的可靠性和耐久性。

摘要： A magneto-optical recording apparatus which records information through the processes of: first irradiating a light beam onto a magneto-optical recording medium having a recording film; and next applying an external magnetic field that is inverted in response to a recording signal onto the recording film while continuing the first process. In the above arrangement, the intensity of the light beam is dropped upon inversion of the external magnetic field so that information is not recorded. The intensity of the light beam is raised during non-inversion of the external magnetic field so that information is recorded. Further the magneto-optical recording apparatus is provided with a light intensity control device for varying the intensity of the light beam dependent of the lengths of recording bits so that the high-temperature area of the recording film is not widened. Since the width of the recording bits is uniformly maintained, the remaining of the recording bit after overwriting operation can be reduced; thus, the signal quality in reproduction can be enhanced.
摘要翻译：一种磁光记录装置，其通过以下处理记录信息：首先将光束照射到具有记录膜的磁光记录介质上; 并且接着在继续进行第一处理的同时将响应于记录信号反转的外部磁场施加到记录膜上。在上述布置中，光束的强度在外部磁场反转时下降，从而不记录信息。在外部磁场的非反相期间，光束的强度升高，从而记录信息。此外，磁光记录装置设置有光强度控制装置，用于根据记录位的长度改变光束的强度，使得记录膜的高温区域不会变宽。由于记录位的宽度被均匀地保持，所以可以减少重写操作之后的记录位的剩余部分。因此，可以提高再现中的信号质量。

摘要： A surface of a magneto-optical recording medium of the present invention is textured with fine and physical protrusions and recessions. The shapes of physical protrusions and recessions vary at each radial locations on the medium such that, for example, rough protrusions and recessions are formed in inner parts of the recording medium and fine protrusions and recessions are formed in outer parts thereof. Therefore, floating force given to a floating head from the medium being rotated based on the constant angular velocity method through an air layer in the outer parts equals floating force in the inner parts. Consequently, since the floating height of the floating head becomes constant irrespective of radial locations on the medium, information can be recorded under constant recording conditions, permitting the accuracy of the recording to improve. Regarding a method for processing the surface of a magneto-optical recording medium relating to the present invention, for example, a texture tape whose roughness is large is used in inner parts of the medium while a texture tape whose roughness is small is used in outer parts thereof. As a result, a magneto-optical recording medium having the above characteristics is produced.
