Patent EP-0436956-A2 (EP)
Inventor: DOUTA HISAYO
IPC: F02D41/12
Filed: 1990-12-28
Abstract: An engine speed control apparatus having an auxiliary air amount controller is disclosed. The apparatus has an actuator (15) which is attached to an engine intake manifold (18) so as to bypass a throttle valve (12) and controls a flow rate of an auxiliary air and a control unit (50) for driving the actuator. The control unit (50) detects whether an engine (10) is in an idling state or not on the basis of a combination of an engine rotational speed and other information. When the idling state is detected, a target value of an intake pressure on the downstream side of the throttle valve (12) is set in accordance with the engine speed at that time. The control unit (50) drives and controls the actuator so that the actual intake pressure coincides with the target value. Thus, when the operating mode of the engine (10) is shifted from the non-idling state to the idling state, an air amount which is required by the engine (10) can be accurately supplied and the engine speed can be rapidly converged to the target value.

Abstract: A sorting method and apparatus is provided in which a flow of particles or objects to be sorted is accelerated by being caused to descend an inclined chute (12) after which the stream or streams discharged from the chute are scanned transversely from one or both sides and while in free fall by one or several linescan cameras (14). The chute may be arranged to divide the flow into separate side by side streams. In a particular arrangement, two cameras scan the streams successively at respective different levels. The linescan data captured by the cameras is then processed to derive signals for operating downstream sorting means (17).

Abstract: An apparatus and method for decreasing the memory requirements of BIOS in a personal computer system (10) includes storing a first portion of BIOS in memory and a second portion on a direct storage access device. The personal computer system (10) comprises a system processor (26), a random access main memory, a read only memory (36), and at least one direct access storage device (62,66). The read only memory (36) includes the first portion of BIOS and data representing the type of system processor (26) and system planar (24) I/O configuration. The first portion of BIOS only includes routines for initializing the system (10) and the direct access storage device (62,66) to read in a master boot record into the system (10) from the direct access storage device (62,66). The master boot record includes a data segment (122-138) and an executable code segment (120). The data segment (122-138) includes data representing system hardware and a system configuration which is supported by the master boot record. The first BIOS portion confirms the master boot record is compatible with the system hardware by verifying that the data from the data segment (122-138) of the master boot record agrees with the system processor (26), system planar (24), and planar (24) I/O configuration. If the master boot record is compatible with the system hardware, the first BIOS portion vectors the system processor (26) to execute the executable code segment (120) of the master boot record. The executable code segment (120) confirms that the system conf iguration has not changed and loads in the remaining BIOS portion from the direct access storage device (62,66) into random access memory (32) superseding the first BIOS portion. The executable code segment (120) then verifies the authenticity of the remaining BIOS portion and vectors the system processor (26) to begin executing the remaining BIOS now in random access memory (32). The remaining BIOS in main memory includes reusable routines for operating the system (10) in a normal manner.

Abstract: A vacuum switch contact material consists essentially of a mixture of Cu and Cr x O y  (x = 1 to 2, y = 0 to 3) wherein Cr x O y  is in a particulate state, the center part of the particles consists of Cr₂O₃ (x = 2, y - 3), and the peripheral part of the particles consists of Cr (x = 1, y = 0). The Cr x O y  particles having Cr₂O₃ central part and Cr periphery can be formed by reducing the surface of Cr₂O₃ particles. Cu may be infiltrated into the open pores of Cr x O y  particles after a green compact of Cr₂O₃ is formed. Alternatively, a mixture of Cr₂O y  particles and Cu particles may be formed into a green compact, which may then be sintered. Still alternatively, a mixture of Cr₂O y  particles and Cu particles may be hot-pressed.

Title: Improved interference suppression in optical communication systems
Inventor: WOOD THOMAS HUNTINGTON
IPC: H04B10/43
Filed: 1990-12-11
Abstract: A technique for suppressing mutually induced interference between spatially separate channels which are positioned nearby one another during a first portion thereof to cause interference therebetween, and are positioned relatively far from one another during a second portion thereof to avoid mutually induced interference therebetween. Energy in one of the channels is converted to a signal which is distinguishable by code, frequency, or time, from energy in the other channel. The converted signal is then transmitted in the second portion of one of the channels. Then, any interference in the other channel caused by the converted signal can be suppressed by suppressing the distinguishable energy from the converted signal.

Abstract: An antimetastable state circuit which detects when a data edge (12) is so close to a clock edge (11) that it would result in a metastable state in a time measurement circuit (16, 17) is provided. When a potential metastable state is detected, the antimetastable circuit delays the data edge with respect to the clock edge by a known amount (27) so as to avoid the metastable state. The delayed edge is used to start the time measurement circuit, and the next clock edge is used to stop the time measurement circuit. When the known delay (27) has been added, it is subtracted from the measured time, to produce an accurate measurement of the elapsed time between the rise of the data edge (12) and the rise of the clock edge (11).

Abstract: Disclosed is an amplifier circuit for concurrently producing low noise electrical output signals which are amplified representations of signals produced by a magnetoresistive (MR) element (11) and protecting said element from electrical short circuits which can occur between said element and its environment. A first feedback loop (14) comprises (a) an input amplifier for amplifying a signal current from the MR element and (b) a source of bias current for biasing the MR element with a bias voltage. An input amplifier is concurrently biased by said current and amplifies a signal current from the MR element for producing a circuit output signal corresponding to dRh/RhRh and in which any differential direct current (dc) output offset error is minimized. (RhRh is the square of the time-averaged resistance of the MR element and dRh is the magnetic-signal-induced change in the resistance of the MR element.) A second feedback loop, (15) electrically in series with the first feedback loop, biases the MR element toward a preselected reference potential and concurrently prevents flow of a current sufficient to damage the MR element in the event of a short circuit occurring between the MR element and its environment (e.g. the recording surface of a magnetic recording disk).
