  • Patent number: 11236533
    Abstract: The present invention aims to reduce the operation noise of a latch device for a vehicle trunk lid when the lid is opened. A latch device for a vehicle trunk lid includes: latch 16 that is engaged with a striker; ratchet 18 that is engaged with latch 16; opening lever 43 that causes ratchet 18 to rotate in a direction in which ratchet 18 is disengaged from latch 16; output member 39 that rotates opening lever 43 in the release direction. Opening lever 43 is rotatable between an unblocked position where it is rotatable in the release direction and a blocked position where it is prevented from rotating in the release direction by colliding with the output member. When driven and rotated, output member 39 abuts against opening lever 43 that is in the unblocked position and rotates opening lever 43 in the release direction to the blocked position, and opening lever 43 is further rotated a predetermined angle by colliding with output member 39 in the blocked position.

  • Patent number: 9039829
    Abstract: Provided is a scale-shaped filmy fines dispersion. More specifically, scale-shaped filmy fines are subjected to a treatment for keeping the scale-shaped filmy fines from easily settling out. In the case of a metallic pigment using the scale-shaped filmy fines, the scale-shaped filmy fines are dispersed in the ink. As a result, nozzle clogging can be prevented, and the obtained print can achieve abundant metallic luster. The scale-shaped filmy fines dispersion contains, in a solvent, scale-shaped filmy fines obtained by finely grinding a simple metal, an alloy, or a metal compound. The scale-shaped filmy fines have a mean length of 0.5 ?m or more and 5.0 ?m or less, a maximum length of 10 ?m or less, a mean thickness of 5 nm or more and 100 nm or less, and an aspect ratio of 20 or more.

  • Patent number: 4742227
    Abstract: A mobile type inspection apparatus for monitoring conditions in an environment or a facility containing radiation and a high temperature has a radiation dosage detector, a temperature detector, and a moisture detector disposed on a movable vehicle. Signals representing the monitored conditions are transmitted to a remote receiver which is included in a control system for operating the inspection apparatus and which has monitors for monitoring the conditions. Signals representing radiation dosage are supplied to a monitor and also to a comparison circuit for comparing radiation resistance limit data for the detectors which is stored in a memory with the detected data so as to generate a device exchange request when the accumulated radiation dosage exceeds the limit of any one of the devices. In a second embodiment, signals representing temperature and moisture are used for monitoring and also to calculate reaction acceleration and using time of the detectors to determine degree of deterioration thereof.

  • Patent number: 4621263
    Abstract: There is dislosed a vibration telemetering system capable of measuring adverse vibrations of installations or equipment in a plant such as a nuclear power plant. The system includes a vibrometer which measures the vibrations in a non-contacting fashion. The direction at which the vibrometer faces is adjusted by an angle adjusting mechanism which is mounted on a travelling unit running along a predetermined inspection route in the plant. A measured signal from the vibrometer is transmitted to a remote control room through a communication system and is used for evaluating whether or not the state of the plant is normal. The remote control room can control the travelling unit and the angle adjusting mechanism through the communication system in order to monitor the vibrations of a plurality of places along the predetermined inspection route.
