  • Publication number: 20200150271
    Abstract: A distance-measurement controller is to be used with an imaging device. The imaging device includes a light source that emits invisible light and a light receiver that receives reflected light. The reflected light is the invisible light that has been reflected by a target object. The distance-measurement controller includes a controller and a distance measurer. The controller causes the light receiver to make images at a constant frame rate, and causes the imaging device to vary a condition for at least two divided ranges into which a range that is a predetermined distance from the imaging device is divided. The condition is a condition under which the images are made to measure a distance from the imaging device to the target object. The distance measurer measures the distance from the imaging device to the target object, based on the reflected light.

  • Patent number: 9140197
    Abstract: A valve timing control apparatus includes a temperature sensing member which expands at a main lock phase when a temperature of an engine is higher than or equal to a predetermined temperature so as to prohibit a main lock component from moving out of a main lock hole to a guide slot. The temperature sensing member shrinks at the main lock phase when the temperature of the engine is lower than the predetermined temperature so as to allow the main lock component to move out of the main lock hole toward the guide slot.

  • Patent number: 8991345
    Abstract: A main lock member is fitted in a main lock bore at a main lock phase for closing an intake valve at a timing later than a timing when a piston reaches a bottom dead center, whereby a rotation phase is locked. In a subordinate lock mechanism, the rotation phase is locked at a subordinate lock phase advancing further than the main lock phase. In a lock control mechanism, a temperature sensing body is changed to an expanded state, whereby a moving member is latched at a first position in which the main lock member is allowed to be fitted in the main lock bore, whereas at a main lock phase in a cold stop state after a timing when the temperature of the stopped internal combustion engine becomes less than a preset temperature, the temperature sensing body is changed to a contracted state.

  • Publication number: 20140366823
    Abstract: A main locking mechanism locks a phase at a main locking phase, at which an intake valve is closed at timing later than a bottom dead center, by inserting a main locking member into a main locking hole. A sub locking mechanism locks a phase at a sub locking phase advanced more than the main locking phase by inserting a sub locking member into a sub locking hole. A movable body disposed in the main locking hole reciprocates between an open position and a blocking position of the main locking hole. During a warm start of an engine, a driving source maintains the movable body at the open position at which the inserting of the main locking member into the main locking hole is maintained. In contrast, during a cold start of the engine, the driving source drives the movable body to the blocking position at which the main locking member is removed from the main locking hole.
