  • CONNECTOR DEVICE AND ELECTRONIC DEVICE
    Publication number: 20090017662
    Abstract: A following control unit 30 is provided. When a connecting-side connector 120 included in a connecting electronic device 100 is connected with a receiving-side connector 20 disposed within a main frame 10 and supported so as to be movable in a connection direction, the control unit 30 controls a movement of the receiving-side connector 20 in a connection direction by applying a pressing force when connecting to the connecting-side connector 120 in the connection direction. The connecting electronic device 100 is a connection-subject. The control unit 30 performs a control by the pressing force when connecting being applied to the connecting-side connector 120 in the connection direction, when the connecting-side connector 120 and the receiving-side connector 20 are being connected.

  • Method for starting up reactor and reactor system
    Patent number: 7468167
    Abstract: A method for quickly starting up a reactor and a reactor system therefor are provided. A shell-and-tube reactor in the system is adapted to circulate a heat medium having a solid point in the range of 50-250° C. to the outside of the reaction tubes and characterized by initiating temperature elevation of the reactor by introducing a gas of a temperature in the range of 100-400° C. to the reaction tubes' side and then circulating the heat medium in a heated state to the outside of the reaction tubes. By introducing a gas of an elevated temperature preparatorily to the reaction tubes, it is made possible to prevent the heat medium after circulation from being solidified again and enable the reactor to be quickly started up.

  • Connector Storing Apparatus and Electronic Device
    Publication number: 20080248666
    Abstract: A main frame supports a receiving-side connector to which a connecting-side connector is connected in movable manner toward inside. A holding unit holds the receiving-side connector that is moved to the inside. A connector biasing unit applies a biasing force toward outside to the receiving-side connector. A hold releasing unit releases a hold by the holding unit, and moves the receiving-side connector to the outside by the biasing force. A pressing-force applying unit applies, when the receiving-side connector is not moved by the biasing force, a pressing force for ejecting the receiving-side connector to the receiving-side connector.

  • Zoom lens and image pickup apparatus having the same
    Patent number: 7428107
    Abstract: A zoom lens includes first to fifth lens units arranged in sequence from an object side to an image side, and having positive, negative, positive, negative, and positive refractive powers in that order. The zoom lens performs zooming by moving the first to fifth lens units. The fourth lens unit includes a negative lens, which is moved in such a manner as to have a component in a direction orthogonal to an optical axis so as to shift an image formed with an entire system in the direction orthogonal to the optical axis. The zoom lens satisfies the condition, 0.50<|ft/f4|<1.50, where ft is a focal length of the entire system, and f4 is a focal length of the fourth lens unit, both at the telephoto end.

  • Method for production of (meth)acrylic acid by use of a shell-and-tube heat exchanger
    Patent number: 7326811
    Abstract: A shell-and-tube type heat exchanger of the smallest possible length necessary for heat exchange is disclosed which is capable of obtaining uniform distribution of flow of a shell side fluid and substantially eliminating the structural restriction imposed on the shell side. This shell-and-tube type heat exchanger is provided with one annular conduit furnished with not less than two partitions concurrently serving as an expansion joint for introducing and discharging a shell side fluid and allowing the flow path for said shell side fluid to be separated into an introducing part and a discharging part and which comprises a place having no array of heat-transfer tubes in the flow path for said shell side fluid. It prevents the equipment from necessitating an unnecessary enlargement due to the structural restriction on the shell side and enables the shell side fluid to produce a uniform flow.
