Title: Viscous fluid type heat generator with means for enhancing heat transfer efficiency
Inventor: TATEMATSU SHOZO
IPC: F24J3/00
Filed: 1998-03-13
Abstract: A viscous fluid type heat generator which includes a housing assembly defining a heat generating chamber and a heat receiving chamber arranged adjacent to the heat generating chamber via a partition wall disposed therebetween. A rotor element is mounted to be rotated by a drive shaft for rotation within the heat generating chamber.  A viscous fluid is held in a gap defined between the inner wall surfaces of the heat generating chamber and the outer faces of the rotor element, for heat generation under shearing stress applied by the rotation of the rotor element.  A heat exchanging fluid circulates through the heat receiving chamber to receive heat transferred through the partition wall from the heat generating chamber.  A plurality of grooves are formed on at least one of the inner wall surfaces of the heat generating chamber to increase a total heat transfer surface area in the inner wall surfaces, and thus to enhance a heat transfer efficiency through the partition wall.  The density of arrangement of the grooves in the outer peripheral area of the inner wall surface is larger than that in the inner peripheral area of the latter.

Title: High current protection circuit for telephone interface
Inventor: WONG WAYNE KWOK-WAI
IPC: H02H9/02
Filed: 1999-03-23
Abstract: A telephone test set protected from an excessive current condition by a protection circuit that maintains sufficient loop current flow for continuous operation of the telephone equipment's functional circuitry. A series current-limiting element installed in the loop current path between a tip and ring interface and the circuitry of the telephone test set. A current shunting circuit installed across the tip - ring ports of the protected circuit downstream of the current-limiting element. A current sense circuit monitors the loop current and controls the operation of the shunting circuit. If a substantial overcurrent condition persists for an extended period of time, the resulting power dissipation associated with the high current flow will cause the current limiting element to change to a high impedance state. Once the overcurrent condition terminates, the series element will revert to its low impedance state.
