Title: Apparatus for controlling a television receiver
Inventor: BEERY JACK
IPC: H03J1/00
Filed: 1990-05-30
Granted: 2000-07-25
Abstract: A television control system is for selecting a television channel corresponding to a preassigned channel tuning designation. A tuner (18) receives mufti-channel input signal (20), and in response to a processor signal, tunes out all but one selected channel. A memory (28) stares at least one operator-assigned channel select designation for the channel tuning designations. An operator-actuated control means (26) generates a first data signal representative of a desired channel select designation for one of the channel tuning designations, and a second data signal representative of a desired viewing channel identified by one of the channel select designations. A processor (30) receives the first data signal from the control means, and in response, causes the memory to store the desired channel select designation as corresponding to the tuning designation. Upon receipt of the second data signal, the processor retrieves from the memory the channel tuning designation corresponding to the channel select designation, and generates the processor signal to correspond to the channel tuning designation.

Title: Engine revolution control apparatus for vehicle
Inventor: OHUCHI HIROFUMI
IPC: F02D31/00
Filed: 1990-07-11
Granted: 1994-04-12
Abstract: ABSTRACT OF THE DISCLOSURE        An engine revolution control apparatus for a vehicle, in which revolutions of an engine when the engine is in the idling state, that is, when the vehicle is being stopped and a throttle valve is totally enclosed, is controlled by con-trolling opening of an air control valve which is provided in a by-pass conduit for by-passing the throttle valve ac-cording to the revolution feedback correction volume which was calculated according to the deviation between the-actual revolutions of the engine and its target revolutions which was set according to the load of the engine, increasing, in the non-idling state of the engine, the revolution feedback correction volume, which is calculated when the engine has shifted from the idling state to the non-idling state as well as when the deviation between the actual revolutions and the target revolutions is small, so that, when the engine is shifted to the idling state again, it is not li-able to be affected by such an undetected current consumer as an ON signal of a headlight which was injected when the engine was in the non-idling state and the actual revolu-tions can smoothly be converged on the target revolutions with better responsibility.
Patent CA-2026471-C (CA)
Inventor: JORGENSEN INER M
IPC: F04D27/02
Filed: 1990-09-28
Granted: 1994-07-26
Abstract: A  circumferentially  supported  fan  assembly  for drawing cooling  air  through  a  radiator  of  a  vehicle  is described.     The   fan   includes   a   fan   ring   extending circumferentially around the periphery of the fan, the blades of the fan extending from a central region to the fan ring. The  entire  weight  of  the  fan  is  borne  by  a  fan  support assembly which extends around the periphery of the fan ring, outside the path of air flowing through the fan.  The fan is the rotor of an electrically driven motor.  A rotor flange of the fan ring extends transverse to the axis of the rotation of the fan, providing a greater torque advantage for the motor. An electrical control circuit selectively controls the speed of the fan to maintain the liquid temperature of the radiator below a selected threshold value.   As additional cooling is required,  the  electronic controller  gradually  and  smoothly increases the power drawn from the engine to turn the fan to increase  its  speed  towards  a  selected  speed.    The  air permeability of the fan when  freewheeling  is  significantly increased because no central shaft or support structure blocks the airflow through the fan.
