  • Patent number: 8988160
    Abstract: A data transmission system is provided in which it is possible to perform both of suppressing the degrading of the slew rate and suppressing the ringing even if load capacitance of an input buffer is changed. The data transmission system transmitting data from an output buffer to the input buffer through a trace is provided with first RC parallel circuits connected in series to the trace on a first Printed Circuit Board (PCB) on which the output buffer is mounted, and second RC parallel circuits connected in series to the trace on a second Printed Circuit Board (PCB) on which the input buffer is mounted, and which can be connected and separated to and from the first Printed Circuit Board (PCB).

  • Patent number: 8866282
    Abstract: A slew rate of a signal transmitted between a semiconductor device having a small load capacitance and a semiconductor device having a large load capacitance is improved. When a signal is transmitted to the semiconductor device (for example, a memory device) having the large load capacitance, pre-emphasis is performed, and when a signal is transmitted to the semiconductor device (for example, a memory controller) having the small load capacitance, pre-emphasis is not performed or is slightly performed. By this, when the signal is transmitted to the memory device, blunting in signal rising due to the load capacitance is suppressed, and when the signal is transmitted to the memory controller, ringing due to the reflection of the signal is suppressed, and the slew rate of the data transmission is improved.

  • Publication number: 20140175756
    Abstract: A lip seal-type shaft seal device that exhibits no leakage when at rest; operates under fluid lubrication and prevents leakage when rotating, including during initial rotation; and enables a balance between seal integrity and lubrication is provided. The device includes a plurality of discontinuous pumping areas for generating pumping action via the relative rotational sliding of a lip seal and a rotating member is formed in the circumferential direction on the outer circumferential surface of the rotating member. The plurality of pumping areas is provided with suction portion of pumping areas operating in a direction in which a sealed fluid is drawn in and discharge portion of pumping areas operating in a direction in which the sealed fluid is expelled. A lip of the lip of the lip seal extends in an axial direction towards an atmosphere side, leaving part of the pumping areas uncovered on a sealed fluid side.

  • Patent number: 8733552
    Abstract: An integrally-rotating cylindrical sieve 1 includes a hollow rotating shaft 2, which a driveshaft 21 is inserted into and fixed to, support members 3 radially extended from the rotating shaft 2, a cylindrical sieve body 4 made from a thin plate with a large number of apertures 5 formed therein, such as punching metal, and coupled with the support members 3, and sieve frames 6a and 6b attached to axial ends of the sieve body 4. The rotating shaft 2, the support members 3, the sieve body 4, the sieve frames 6a and 6b, and the driveshaft 21 are coaxially rotated together. The sieve body 4 is a cylindrical corrugated plate having wave crests and wave troughs arranged along its circumference and has a large number of apertures 5 formed in the corrugated plate. This arrangement improves the sieving efficiency of the granular material and effectively prevents potential destruction and cracking of the granular material, thus enhancing the commercial value of the sieved granular material.

  • Patent number: 8708343
    Abstract: A seal device where a seal lip reliably maintains shaft sealing relative to high-pressure fluid that is to be sealed and where the equivalent Mises stress occurring in the seal lip is reduced to extend the durable term of the seal lip longer. A backup ring has a tapered section continuously extending from a fixation section of the backup ring and also has a forward end section. A rounded surface (E) with a curvature radius (R-1) is formed at least at a boundary where a surface (D) of the tapered section changes to a surface (F) of the forward end section. A portion of the surface (D) of the tapered surface, which portion is in contact with the rounded surface (E) at the boundary, is a projected curvature surface having a curvature radius greater than the curvature radius (R-1) of the boundary.
