  • Semiconductor cooling apparatus
    Patent number: 4977444
    Abstract: Flexible cooling paths are connected to semiconductor elements which are heated members. A cooling apparatus comprises cooling blocks connected to cooling blocks, coolant flow paths through which the coolant flows, coolant branching mechanisms provided in the coolant flow paths and connecting mechanism for connecting the branching mechanism and the cooling blocks through O-rings. A part of coolant flowing through the cooling flow paths is introduced into the cooling blocks for the respective heated chips in order.

  • Sealed structure and production method thereof
    Patent number: 4872606
    Abstract: In a sealed structure consisting of ceramic members opposing each other and a frame coupled to the ceramic members and defining an He-tight chamber with the ceramic members, the melting point of a joint member for bonding one of the ceramic members to the frame is lower than the melting point of another joint member for bonding the other of the ceramic members to the frame so that rebonding can be made.

  • Device for identifying rubbing locations in rotating machines
    Patent number: 4377947
    Abstract: A device for identifying an acoustic sound producing location in an axial direction of a rotating body by using an acoustic signal and a rotational pulse signal. In the device, a rubbing location identifying signal is provided in synchronism with the rotational pulse signal in which the pulse interval corresponds to the distance between acoustic sensors or a rotor length. A phase of a peak in a rubbing location identifying signal as measured with respect to the pulse represents an acutal rubbing location.
