A switching power supply device in which the increase in the switching frequency when the load is light is restrained, whereby the switching loss is reduced, intermittent oscillating operation is prevented, and heat generation in the main switching device at the time of short-circuiting is restrained. In a switching po...
A gas-discharge display panel includes a third group of electrodes in addition to the first and second groups of electrodes found in a conventional gas-discharge display panel. A series of control discharge spaces are respectively formed at those positions where the third group of electrodes mate with the first group o...
A signal processor for use in a small, lightweight radar-guided missile to provide a discrete Fast Fourier Transform (FFT) on received radar return signals. The radar return signal are converted into a sequence of binary digits enabling a simple decoder to perform complex addition and subtraction processing, thereby mi...
In ignition timing control system for an internal combustion engine, a knocking detector is provided to detect knockings of the engine, and a control unit responsive to the knocking signals of the knocking detector to provide a variable retard amount signal per one knocking which depends on whether the occurrence of an...
In this wireless remote control system, control signals and reporting-back signals are bidirectionally transmited between at least one portable transmitter-receiver unit, a stationary transmitter-receiver unit and a control. The portable transmitter-receiver unit contains a microprocessor and is carried, for example, b...
A computer system which utilizes two different sets of address control and state information signals for transferring information of the same or different widths is disclosed. The use of two sets of signals allows master units to utilize only one set and a system board determines when the second set of signals must be ...
To replace conventional ball-cage strips for remote controls in which push-pull blades slide on ball bearings maintained properly spaced from one another by such strips, a linkable ball-cage element has been developed to form strips of such linked elements that overcome limitations of prior ball-cage strips. Each eleme...
A method and an apparatus for control of engine fuel injection are characterized by detecting the state of the acceleration of the engine and also judging whether or not the engine is in a specific acceleration state, by, when the engine is judged to be in a specific state of acceleration, using such a value as a crank...
An anti-skid brake control system detects wheel acceleration greater than a predetermined value. The predetermined value is set greater than an acceleration threshold which is used for switching operational mode from braking pressure decreasing mode (RELEASE mode) to decreased pressure hold mode (HOLD mode). When the w...
A surface potential measuring meter and an electrostatic recording apparatus are disclosed. The surface potential measuring meter detects the surface potential on an object to be measured as AC signal. The electrostatic recording apparatus is provided with the surface potential measuring meter to measure the surface po...
A fuel supply control method for multicylinder internal combustion engines, includes calculating the quantity of fuel being supplied to the engine in response to operating conditions of the engine, and sequentially supplying quantities of fuel corresponding to the calculated values into respective corresponding ones of...
An engine case of a gas turbine engine is selectively coated with a thermal barrier coating to control axial clearance between rotating and stationary airfoils. The coating is applied to the thinner portions of the engine case to retard thermal expansion of these portions of the engine case during transient conditions ...
A liquid crystal display is driven so that an arbitrary pair of neighboring ones of M×N matrixed pixels in a row direction are driven by reversing a polarity of a signal potential in either thereof from that in the other thereof, an arbitrary pair of neighboring combinations of neighboring two of the M×N pixels in a ...
An underwater acoustic control system for use in a subsurface unit receiv coded signals. A hydrophone receives the signal and enables an electronics package to supply a control pulse which could activate a switch or fire a squib. A timer is included in the package to provide a delayed turn-on of the receiver circuit f...
A vehicle surroundings monitoring apparatus inputs images from a stereoscopic camera and signals of vehicle speeds, steering angle and yaw rate and detects front information such as solid object data, side wall data and lane marker data to estimate a traveling path of an own vehicle from the front information and trave...
A charge/discharge control circuit comprises two serially connected electric power sources and two overcharge/overdischarge detection circuits. A control circuit outputs a signal for controlling the charge/discharge of the electric power sources in accordance with signals from the two overcharge/overdischarge detection...
A system for controlling the slip of driving wheels of a vehicle detects an excessive slip state of at least one of the driving wheels of the vehicle wherein the slip of the at least one driving wheel has a magnitude greater than a predetermined magnitude, and interrupts fuel supply to the engine of the vehicle when th...
An electronic control system for internal combustion engines wherein the duration of injection is proportional to a regulating voltage controlled by at least one operative parameter of the engine. To this end an input voltage defined by a succession of sides of a polygon is subjected to a plurality of transistorized ci...
