Abstract: A control apparatus for electrically operating a throttle valve (M₈) adapted to adjust the amount of air drawn into an internal combustion engine to adjust the position of the throttle valve (M₈). The position and operating condition of an accelerator pedal (M₁) are electrically detected to generate a signal in accordance with the accelerator position to drive an actuator (M₅) adapted to operate the throttle valve (M₈) , and also a desired throttle position established by the signal, the detected actual position of the throttle value (M₈) and the operating condition of the accelerator pedal (M₁) are suitably compared and examined, thus monitoring to see whether the detection of the accelerator position is not faulty, whether the throttle valve (M₈) is controlled to follow the desired throttle position and so on and thereby performing a safe control by using a substitute desired position upon occurrence of a faulty condition. Also, during the period of acceleration/­deceleration, a driving signal is generated to operate the throttle valve (M₈) to suit the engine operating condi­tion. Further, when the actuator (M₅) steps out of synchronism, an evacuation control is performed.

Abstract: An apparatus (10) for providing while drilling infor­mation on a subterranean geologic formation (28) includes a drilling rig (12) and a rotary drill bit (18) attached to the drilling rig (12) for providing seismic waves as it drills in the earth (16). Geo­phones (20) are spaced from the rotary drill bit (18) in the earth (16) and receive in direct seismic wave paths (26) and seismic wave paths (30) reflected from the subterranean geologic formation (28) the seismic waves provided by the drill bit (18). A reference sensor (24) is located on the drilling rig (12). The seismic signals sensed by the reference sensor (24) and by the geophones (20) are cross-correlated to separate the drill bit generated signals from inter­ference signals by combining the reference signals and the signals received by the geophones (20). The cross-correlated reference signals and the signals received by the geophones (20) are separated into a first group of the drill bit generated seismic signals travelling to the geophones (20) in direct paths and a second group of the drill bit generated seismic signals travelling to the geophones (20) in paths reflected from the subterranean geologic formation (28). The cross-correlation provides a domain where drill bit generated energy can be distinguished from interference. The two groups of the drill bit gener­ated seismic signals can then be used to image the subsurface seismically so as to improve the chances of discovering hydrocarbons. The technique is applicable to land operations and to drilling from an offshore platform over water.

Abstract: A semiconductor memory according to the present invention includes a plurality of cell blocks (100-111), a refresh control circuit (2) which sequentially refreshes a plurality of the cell blocks, an access control circuit (3) which accesses a plurality of the cell blocks, and an ECC circuit (5) which is provided in a data path between the access control circuit and the plurality of cell blocks, so that the data which is input from and output to the access control circuit is converted to a predetermined bit converted data (so called code) by the ECC circuit and is stored in the plurality of cell blocks. Accordingly, when the access control circuit accesses the plurality of cell blocks, if the access can not be carried out for specified cell block which is in a refresh state (that is, a correct data (code) can not be written to or read from the cell block in a refresh state) the data in the access control circuit side can be reproduced as correct data by the ECC circuit. Therefore, viewed from the external, a predetermined access can be carried out without being affected by the refresh state.

Abstract: A data modulation interface is provided for serial data transmission. A biphase signal is encoded with the binary bits of a parallel data word. The bits of the parallel data word are examined to determine whether there are more one bits or zero bits in the word. A polarity bit is provided in addition to the other bits to indicate which bit-state occurred most often. The biphase signal is modulated to create dif­ferent time intervals between phase reversals with one time interval corresponding to a bit-state of one and another time interval corresponding to a bit-state of zero. The shortest time interval is assigned to correspond to the bit-state occurring most often in the word so that the total time required to transmit each word is minimized. A time interval can be assigned to a sync signal transmitted after each parallel data word. A time interval can also be assigned to correspond to plural bit combinations so they can be represented by a single phase interval and transmitted quickly.

Abstract: A process is disclosed for fabricating improved integrated circuit devices. In accordance with one embodiment of the invention integrated devices are fabricated by a four layer poly process which produces small device areas without relying upon restrictive photolithography tolerances. A master mask is used to define the basic footprint of the device in combination with easy to align block-out masks in each lithography step. A double implant doping process is used to control the Gummel number in the base of bipolar transistors and like regions. A shallow implant is placed in a screen oxide and a deep implant into the desired base location. The dopant saturated screen oxide prevents segregation of the deep base implant during subsequent heat treatment. The double implant process applies to many desired device structures.

Abstract: A digital circuit for measuring the peak amplitude of a pulse and indicating the time at which the peak occurred. The pulse signal is sampled at clock intervals and digitized. The first sample that is greater than a threshold is stored in a peak register, and a preset timer is started. If, before the timer times out, a subsequent amplitude sample is received having a greater amplitude, it replaces the stored one. The timer is then restarted. This replacement procedure is repeated until the timer times out without any superseding greater amplitude sample having been received. A strobe pulse is then generated. A pulse validation circuit and a noise suppression circuit are also disclosed.
