  • Patent number: 9643602
    Abstract: A parking support device 1 includes a calculation unit 17 that calculates a speed pattern, an acceleration recognition unit 13 that recognizes driver-requested acceleration, a parking support control unit 19 that performs parking support control in a target parking position based on the speed pattern, and a determination unit 18 that determines whether a host vehicle V can stop in the target parking position at a set deceleration. When the driver-requested acceleration is recognized during the control and exceeds acceleration of the speed pattern at the time of recognition, the parking support control unit 19 accelerates the host vehicle V at the driver-requested acceleration. When the determination unit 18 determines that the host vehicle V can stop in the target parking position at the set deceleration, the host vehicle V is decelerated at the set deceleration and is stopped in the target parking position regardless of the driver-requested acceleration.

  • Patent number: 7818709
    Abstract: Circuit-pattern-data correction method and semiconductor-device manufacturing method which prevent excessive correction from being made when model-based proximity-effect correction (OPC) is applied to a corrected circuit pattern, the excessive correction being caused by a step (difference in level) close to a circuit-pattern corner in the corrected circuit pattern, and the step being produced when rule-base OPC is applied. The rule-based OPC is applied to input design data in step S1; a step close to a circuit-pattern corner, produced by the rule-based OPC is detected in step S2; the step is removed in step S3; and the model-based OPC is applied and exposure data is generated in step S4.

  • Publication number: 20100106364
    Abstract: A transmission cycle/output control portion (20) controls at least one of a transmission output of an inter-vehicle communication device (22) and a frequency of transmission from the inter-vehicle communication device (22) according to the speed of a host vehicle (100) detected by an in-vehicle sensor (12) so that the at least one of the transmission output and the frequency of transmission is set to a lower value as the speed becomes lower. In the case where the in-vehicle sensor (12) and a deceleration determination/gradient calculation portion (16) determine that the host vehicle (100) decelerates, the transmission cycle/output control portion (20) executes a control so that the at least one of the transmission output and the frequency of transmission is high as compared to the case where it is determined that the host vehicle (100) does not decelerate. Therefore, when the host vehicle (100) does not decelerate, communication traffic is reduced.

  • Patent number: 6229484
    Abstract: A high efficiency antenna device suited for use in a mobile unit is provided. A pair of triplate antennas are stacked, in which a lower antenna includes a feeding probe for a horizontal polarization and an upper antenna includes a feeding probe for a vertical polarization. The feeding probes have patch edges at opposing ends in the polarization direction. A coupling slot for coupling the upper and lower antennas are disposed over the patch edges in the lower antenna. In-phase magnetic current runs through the patch edges, so that a phase match is obtained between the two slots, raising antenna efficiency. The feeding probe is disposed at an angle and oriented in a direction corresponding to a representative value of polarization angels of the traveling area, to thereby reducing polarization angle loss as a whole.

  • Patent number: 6020858
    Abstract: A plate antenna for use with polarized waves, wherein pairs of slots are formed in a parallel-plate waveguide, feeding waveguides supply mutually orthogonal TEM waves, the pairs of slots are arranged in a V-shaped pattern, adjacent slot pairs are arranged in mutually opposite directions, the antenna beam can be tilted by adjusting the space between the pairs of slots, and the pairs of slots can induce electric fields in the same direction for horizontal and vertical TEM waves. It is then possible to transmit and receive a horizontal polarized wave and a vertical polarized wave even when the antenna beam is tilted.

  • Patent number: 5083218
    Abstract: A hand-held image reading apparatus reads image data corresponding to image information from a surface and prints the image data on a printing medium. The apparatus reads the image data by moving over the surface. Further, the apparatus stores the read image data in an internal memory, extracts the image data existing in the center of the image data stored in the memory and prints only the extracted image data on the printing medium.

  • Patent number: 4949283
    Abstract: A manually sweepable printer stores data transferred from a data forming apparatus such as a wordprocessor in a memory. The printer is placed on printing paper and manually swept to sequentially print the data stored in the memory. The manually sweepable printer separately receives printing data and print control data from the data forming apparatus and separately stores the received data. In the printing operation, the printing data is printed on the basis of the print control data.

  • Patent number: 4915027
    Abstract: A manually operable sweeping-type compact printer apparatus includes a key entry unit, a display unit, a memory unit, an encoder and a printer unit which are mounted on a manually manipulatable housing. When the housing is manually moved over a printing medium with the printer unit in contact with the printing medium, data entered by the key entry unit is printed out on the printing medium. In the printer apparatus, only designated segments or lengths of data are printed out on the printing medium, independent of continued travel or movement of the housing. Also, even if the housing is moved over the printing medium at an unstable moving velocity, high printing quality can be realized by control of the printing head. Stop codes designating the end of a data segment can be automatically or manually inserted.
