  • Patent number: 10344724
    Abstract: In a high-pressure pump, a relief valve main body has a rod shape. A relief valve seat portion is integrated with an end of a relief valve main body so as to be capable of contacting a relief valve seat. The relief valve main body is inserted into a guide hole portion of a support portion. The guide hole portion slidably supports an outer wall of the relief valve main body so as to guide a reciprocating movement of the relief valve main body in the axial direction. A fuel guide portion is provided at an end portion of the relief valve main body facing the pressurizing chamber and can guide a flow of the fuel in a direction radially outward of the relief valve main body on the way from the pressurizing chamber toward the valve seat portion.

  • Publication number: 20180172471
    Abstract: An information communications system (100) for a vehicle includes an on-vehicle information device (10). The on-vehicle information device (10) includes: an information collection unit (11) which collects vehicle information from an on-vehicle device (41, 42, 43, 44), communication interfaces (14A, 14B) connected to mobile terminals (20) having a communication function and being brought inside the vehicle, and a control unit (12) which transfers the vehicle information collected by the information collection unit (11) to any one of the mobile terminals (20) via any one of the communication interfaces (14A, 14B). If one of the mobile terminals (20) currently selected as a destination of the vehicle information satisfies a predetermined condition, the control unit (12) switches the destination of the vehicle information to a different mobile terminal (20). The mobile terminal (20) which received the vehicle information transfers the vehicle information thus received to a center device (30).

  • Patent number: 7110041
    Abstract: A teletext data separation apparatus has a slice level generating circuit including a slice timing control circuit, a control register, an adder and a divider. The slice timing control circuit generates a timing signal for sampling. The control register carries out ON/OFF control of the slice timing control circuit. The control register sets by its register value the number of the sampling points of the adder and divider. By varying the register value in response to the reception state, the number of the sampling points can be increased from the specified 16 points, for example. This makes it possible for teletext data separation apparatus to generate an appropriate slice level that enables the teletext data to be separated reliably even in conditions where noise or distortion occurs in the video signal because of the effect of a weak electric field or ghost.

  • Publication number: 20060000809
    Abstract: A method for fabricating a glass substrate for information recording media. A uniform texture can be formed in a major surface of the glass substrate without degrading the smoothness of the major surface. The method comprises a step of forming a texture in a major surface of a disk-shaped glass substrate by lapping the major surface with a lapping member while supplying an abrasive material onto the major surface. In the step, the glass substrate is reciprocated in a radial direction while rotating the glass substrate around its center at a predetermine rotational speed. The rotational speed, the reciprocating speed, and the reciprocation stroke are so determined that the locus of every particle of the abrasive material crosses itself at least at three points.

  • Patent number: 6370319
    Abstract: A digital recording apparatus receives an analog signal containing picture and/or voice information, through an analog transmission line, and digitally records the analog signal. The analog signal is digitally recorded in a form containing electronic watermark information within a first portion of the analog signal containing the picture and/or voice information while adding copy control information indicating permission of free copying to a second portion of the analog signal not containing the picture and/or voice information when the detected electronic watermark information indicates permission of free copying. Digital recording of the analog signal is prohibited when the detected electronic watermark information indicates prohibition of copying, and the analog signal is digitally recorded with the copy control information indicating prohibition of subsequent recording added to the second portion of the analog signal when no electronic watermark information is detected.
