摘要： An optical memory apparatus employs an optical disc having a plurality of guide-grooves in spiral and concentrical form and a plurality of flat tracks each arranged between adjacent two of the guide-grooves for recording information thereon, and the depth of the guide-grooves is suitably selected to increase the degree of modulation of a track cross signal, thereby performing a stable cross track counting by the use of the track cross signal and a tracking signal. One feature of the invention relies in that the modulation degree of the track cross signal is in the range between 30 and 60%. A second feature of the invention is that the guide-grooves are formed into a V shape and have an optical depth of .lambda./6 to .lambda./5 (.lambda. is the wavelength of the light used). In accordance with the invention, not ony a stable cross track counting is realized, but also the tracking signal is not practically varied with variations in the depth of the guide-grooves, thereby ensuring a highly accurate and stable tracking control.

摘要： An optical recording medium on which information is recorded by irradiating the medium with a light spot to cause a characteristic change of an actual reflection factor, the optical recording medium including grooves of different optical depths which extend in a direction in which the light spot is moved relative to the medium and which are alternately and periodically formed in a direction perpendicular to the relative movement direction of the light spot so that a plurality of grooves thereof can be covered by the light spot, and mark recording regions provided on the flat surfaces between the grooves, the pitch of the flat surfaces between the grooves being selected to be substantially half the diameter of the light spot, thus increasing the recording density and preventing the cross-talk. A method and apparatus for reproducing the information recorded on the medium are provided. Of the reflected and diffracted light distribution obtained by irradiating the light spot on the optical recording medium, the intensity change of the 0-order and third-order interference regions on the shallow groove's side are detected in the form of electrical signals, and information signals corresponding to mark are reproduced on the basis of the detected signals.

摘要： A seal structure has one metal gasket arranged between a pair of casings. The metal gasket is provided with a planate outer peripheral portion and a bead portion which is formed by rising up from an inner peripheral end portion of the outer peripheral portion, and is arranged so that the bead portion comes into contact with the one casing, and the outer peripheral portion comes into contact with the other casing. The bead portion elastically deforms so as to reduce its height and the outer peripheral portion elastically deforms on the basis of the elastic deformation of the bead portion, when the metal gasket is pinched by the pair of casings, and a leading end of the outer peripheral portion comes into contact with one casing at this time, whereby any gap in which salt water stays is not formed between one casing and the metal gasket.

摘要： A vehicle drive unit, for quickly recovering a grip even if a wheel slips, in which in a slip state or at a time when the slip state is going to be generated, by pulsating a torque applied to the wheel, an angular velocity W of the wheel is changed so as to change the slip ratio S close to a slip ratio at which a friction coefficient becomes maximum, and thus, an average of a friction coefficient μ is enlarged and an average of a vehicle driving force F generated by a wheel is enlarged. Since the vehicle driving force is enlarged, the vehicle is accelerated and is easily gripped. Further, in a grip state or at a time of traveling at a high velocity, a vibration and an undesired sound are suppressed by doing away with the torque pulsation or making the fluctuation band of the torque pulsation small.

摘要： An electrically-controlled throttle valve apparatus includes a motor, a speed reducing mechanism for reducing the rotation speed that is transmitted from the motor, a throttle valve connected to the speed reducing mechanism, and a force applying arrangement for applying force to the throttle valve in the direction of returning the valve to its initial position and for adjusting the opening of the throttle valve by driving the motor. Specification parameters of the motor, the speed reducing mechanism, and the force applying arrangement have values such that the operation time t from the minimum opening to the maximum opening of the throttle valve, which is determined by an evaluation equation obtained from equations of motion of the throttle valve, is less than a prescribed target operation time t* of the throttle valve. Furthermore, the resistance and the induction voltage constant of the motor are determined so as to satisfy a constraint equation obtained based on Ohm's law.
