A battery saving circuit for a battery powered receiver composed of a receiving section, a waveform shaping section and a control section, the waveform shaping section requiring a predetermined time after being connected to the power supply to become operational. The battery saving circuit includes a calling signal detector, first and second timers responsive to the detector output and first and second switch circuits responsive to the first and second timers, respectively. The first and second …

A pipeline-controlled data processing system includes decoding apparatus for decoding successive instructions and a detection device responsive to the decoding apparatus output for determining when a particular two-instruction sequence is present. When a first instruction calls for an operation to be executed and the execution result to be loaded into an arithmetic register, and when a second instruction immediately following the first instruction calls for the storing of the output of the arith…

A multilayer wiring substrate composed of organic dielectric layers with wiring layers disposed therein supports large-scale integrated circuit chips and bonding pads. To prevent damage to the wiring layers when wires from the integrated circuit chips are attached to the bonding pads by thermocompression bonding, a metallic layer is interposed between the wiring layers and the bonding pads.

A klystron tuning control system has a D.C. motor which is connected to the tuning shaft of the klystron. The position of the tuning shaft is detected electrically and used to control the turning of the D.C. motor in order to reduce to zero a difference between the output voltage of the detecting means and a reference voltage. At zero, a coincidence signal is produced so that a counter means may count a predetermined number and provide an output responsive to which the D.C. motor is operated in …

In a method of driving a solid-state imaging element, an operation of reading charges from a photoelectric conversion element to a vertical transfer register of an imaging region and an operation of clearing charges by discharging them to an overflow drain are performed plurality of time within one field period.

Good electrical connection between adjacent metal layers in a multi-layered substrate is provided by embedding a conductive material in via-holes in the insulator which separates the adjacent metal layers. This conductive material can be a low temperature sintered metal such as gold, or a conductive organic paste. The presence of the conductive material avoids problems associated with photoresist material that adheres to the side walls of the via-holes during the metallization process.

An interference cancellation type space diversity system transmits digital microwaves in a sure and stable manner. Signals coming in through two spaced antennas are combined together into a single input signal and the composite signal is processed by a demodulator into a baseband signal which is identical with a transmitted signal. The demodulated baseband signal is processed by a frequency/amplitude characteristic detector network, which comprises a correlation circuit and an identification cir…

An approximation control code is initially set to logic “1” except for the MSB which is set to logic “0”. At the m-th comparison, if a sampled analog signal is greater than a comparison reference signal proportional to the control code, the m-th and (m+1)th MSBs of the control code are replaced by logics “1” and “0” respectively, and, if the sampled analog signal is less than the comparison reference signal, the (m+1)th MSB is replaced with logic “0”.

A bidirectional constant current driving circuit is connected between the positive and negative terminals of a power supply. This drive circuit has an input terminal and an output terminal with a load coupled to the output terminal, and with the current supplied thereto being controlled to vary in either a positive or a negative electrical direction. The inventive driving circuit has four transistors . A first and second of these transistors have a first electrode connected to the first power su…

An ink jet printer is disclosed wherein an ink writing head is reprocably movably mounted on an eccentric guide shaft to scan a print line during print mode and moved to a cleaning position outside the print line during non-print mode. A nozzle cleaning device movably supports a liquid-absorbing cleaning tape along a path parallel to and adjacent to the nozzle surface. A drive system turns the guide shaft about the eccentric axis thereof and moves the cleaning tape during the non-print mode so t…
