  • Patent number: 6589708
    Abstract: There is provided improvement of a light-heat conversion in a light-stimulated writing method. An image recording body includes an element, which absorbs light (electromagnetic wave), provided in a surface of a recording body 10, or in a recording layer formed on uppermost layer of the recording body having a material exhibiting thermal changeable character of wettability, or in a substrate or an intermediate layer of the recording body. After a liquid is on the recording body 10 by a liquid forming means 3, light-stimulated writing is carried out. When the light-stimulated writing is carried out with light (electromagnetic wave) from a light (electromagnetic wave) source according to image information, an efficiency of light-heat conversion can be enhanced by a light (electromagnetic wave)-absorbing element.

  • Patent number: 6483430
    Abstract: A control circuit generates a right-turn or left-turn signal from a direction indicator lamp based on a direction indicating signal from a turn signal switch in a scooter as a vehicle. The control circuit then calculates a turning angle of the scooter from an angular speed V of the scooter detected by an angular speed sensor, and cancels the turn signal generated from the direction indicator lamp on the condition that the turning angle be equal to or greater than a reference turning angle, that a vehicle speed N detected by a vehicle speed sensor be equal to or higher than a reference vehicle speed, and that the angular speed detected by the angular speed sensor be equal to or lower than a reference angular speed.

  • Patent number: 6366276
    Abstract: A method and apparatus are provided for reliably detecting a touch operation in a touch sensitive control surface, despite the influence of light or the existence of an obstruction. In the touch tracer, LEDs and phototransistors for detecting a touch position on the input pad are arranged to form parallel optical axes in the vertical direction and the horizontal direction. The optical axes of the LEDs and the phototransistors are alternately arranged in opposite directions to the adjacent optical axis. Moreover, the front surface of the phototransistor is closed except for an aperture that forms an optical axis only between opposing LEDs. The apertures are divided in half into top and bottom portions by a light-shielding film. Because of the light-shielding film, the phototransistor does not receive any light interference from the adjacent LED or incidental sunlight.

  • Patent number: 6232961
    Abstract: A display device is disposed in a car and a display screen is switched based upon coordinate data showing the touched position which is output from a touch tracer which is disposed where it can be accessed by a driver, and “on” data that shows that the touch tracer has been press-operated. The display device displays small button display portions to select a next display operation which is to be displayed on the map screen. The button display portions which are shown on the map screen in an input state of the coordinate data from the touch tracer are displayed in an expanded state. By so doing, the driver can easily confirm the display content of the button display portions so that it is possible to improve the operability of the touch tracer for the selection of the button display portions.

  • Patent number: 6198475
    Abstract: A touch operation information output apparatus is provided in a position at which a driver can operate it, and detects a touched position with respect to the input pad and outputs its coordinate data to the display device. Here, protruding brackets are provided at 16 positions on the input pad. A first group of protruding brackets that are in 4 positions at a center of the input pad are formed in a “+” shape, a second group of protruding brackets that are in four corners of the input pad are formed in an “L” shape and a third group of protruding brackets are formed in a “T” shape. Because of this, the driver can recognize the touched position with respect to the touch operation information output apparatus and blind operation becomes possible.

  • Patent number: 5685405
    Abstract: A shift lock apparatus which allows a shift interlock wire and a key interlock wire to be arranged more effectively and neatly within the vehicle body. A lock pin engages with a first engagement portion perpendicularly each other. The shift interlock wire is linked with the first engagement portion and moves as a shift lever is locked or unlocked. The lock pin is moved by a brake pedal when the brake pedal is released. When a key inserted into a key cylinder is rotated from an ACC position to a LOCK position, the key interlock wire moves to establish engagement with a second engagement portion. Both wires intersect each other, and also the lock pin and the wire intersect each other, thereby providing secure operation and a shorter and neater layout of wires when a housing is installed within the interior of the vehicle.

  • Patent number: 5309744
    Abstract: The present invention is directed to a shift locking apparatus for blocking a shifting movement unless a special operation is conducted such as the depression of a foot brake by an operator, when a shift lever of an automatic transmission is moved from a specified shift position of a parking "P" and the like to another shift position, wherein when releasing of the shift lock is conducted by an electrically operated actuator such as a solenoid, the shift lock can be released by use of a key for a vehicle even in a condition where the electrically operated actuator is not used. The operation of a key cylinder by use of the key of the vehicle by the operator causes the shift lock to be released, ensuring that the operator can move the shift lever to any other shift position, thereby permitting the vehicle to be moved even if there is some trouble such as electrical trouble.

  • Patent number: 4972692
    Abstract: A key-operated ignition device which prevents an engine starter from being driven while the engine is already running, so to protect the starter and engine from damage. The device comprises a key-operated rotor disposed in the device for turning a locking cam via a coupling plate to shift an ignition switch between off, on and start positions. A sliding member is selectively movable between first and second positions by a restriction plate, wherein when the sliding member is in the first position the rotor may be turned from the on position to the start position and when the member is in the second position, the rotor is prevented from again turning from the on position to the start position, without first turning to the off position. The restriction plate also prevents the rotor from being directly turned from the off position to a lock position.
