Title: Anti-cocking with fail safe system
Inventor: MEKOSH JR GEORGE
IPC: B60T8/46
Filed: 1980-05-01
Granted: 1985-02-27
Abstract: The anti-lock system in a vehicle includes a valve system having normally closed valves responsive to the speed of the wheel of the vehicle. Pressure within the valve system controls the application of the braking pressure. Normal braking pressure is applied during normal deceleration of the vehicle. The valves open to release the pressure in the valve system to prevent braking during excessive deceleration of the vehicle. A time dealy mechanism renders the valve system ineffective when the pressure drops and remains below a predetermined level for a predetermined time interval, to thus permit normal braking to be resumed.

Title: Electronic conference system
Inventor: IMAI RYUSAKU
IPC: H04N1/42
Filed: 1984-06-28
Granted: 1989-03-10
Abstract: This system has stations each with a data input unit for picture data, a storage unit for data of a number of pictures, a display unit.  The control unit is for adjusting storing of the picture data input, the display, and transmitting data to or receiving data from, another station.  This system with picture data control uses some absolute number to supervise the same picture data in all remote stations.  The presence in the storage unit of a number equal to this other absolute number is discriminated and the result transmitted back to the second station.  If such a number is not stored the second station transmits its picture data to be received by the first station.  The same picture data stored in different stations is thus supervised by the same absolute number.

Title: Latch-up protection circuit for integrated circuits
Inventor: WINNERL JOSEF
IPC: H01L21/8242
Filed: 1987-09-15
Granted: 1996-07-25
Abstract: A latch-up protection circuit for an integrated circuit using complementary MOS circuit technology has a substrate bias generator that applies a negative substrate bias to a semiconductor substrate having a p-conductive material into which a well-shaped semiconductor zone of n-conductive material is inserted. In order to avoid latch-up effects in the integrated circuit, an electronic protection circuit interrupts the capacitive charging currents of a capacitor in the substrate depending on the potential of the semiconductor substrate which is taken at a doped substrate bias terminal. The electronic protection circuit connects a capacitor bias generator to the capacitor when a voltage on the substrate bias terminal is less than a sum of a reference potential and a threshold voltage of a first transistor in the electronic protection circuit. The electronic protection circuit disconnects the capacitive bias generator from the capacitor when a voltage on the substrate bias terminal is greater than the sum. During normal operation the electronic protection circuit does not load a supply voltage source or a substrate bias voltage source with current.
