An internal clock generator that modulates a high-frequency clock signal to a low-frequency signal to transmit the low-frequency signal if a transmission line for transmitting the high-frequency clock signal is long, and then restores the transmitted low-frequency signal to the high-frequency signal. The internal clock generator includes a first signal generation unit for receiving a first signal having a first frequency and generating a second signal having a second frequency that is lower than...

The invention concerns an internal-combustion engine, the engine comprising an engine housing having a first wall delimiting a first combustion chamber, a first connecting rod having a first piston and a second connecting rod having a second piston. The pistons also delimit the first combustion chamber. The first wall defines at least a section of a torus, and the pistons are guided along a curved path defined by the section of the torus. The connecting rods are coupled to an intermediate member...

A personal computer, comprising a microchip, the microchip comprising at least four microprocessors, exclusive of any digital signal processors (DSPs); a non-volatile memory component; a power management component; a internal firewall with a hardware component, the internal firewall being configured to allow and/or deny access to portions of the microchip both to a user of the personal computer and to a user of the microchip from a network of computers during a shared use of the microchip, and t...

An engine controller performs low opening degree control during a first intake stroke period since an engine start is commenced until first intake strokes of respective cylinders end. Thus, an opening degree of an intake throttle valve is controlled to a fully closed position or proximity of the fully closed position such that intake pressure downstream of the intake throttle valve becomes equal to or lower than critical pressure with respect to intake pressure upstream of the intake throttle va...

This door consists of: an internal structure (16) in which at least two compartments are executed; a panel (18) mounted in each of the compartments, and holding means of each panel (18) in the corresponding compartment. These means permit the release of the panel when a predetermined load, in a given direction, is applied to this panel.

The present invention provides an internal combustion engine which can produce several types of fuels from a single fuel as needed. The internal combustion engine comprises reforming means 3 for reforming a first fuel to be used in homogeneous charge compression ignition combustion into a second fuel having high ignitability, by making the first fuel contact with a catalyst formed from N-hydroxyphthalimide. The engine uses the second fuel when conducting diesel combustion. The engine can switch ...

In a supercharged internal combustion engine having a plurality of cylinders which are arranged in at least one cylinder bank, preferably a V-type engine with an exhaust gas turbocharger including a compressor, which is arranged in an intake line of the internal combustion engine and a turbine which is arranged in an exhaust gas collection line, the exhaust gas of a plurality of cylinders of the cylinder bank is combined in an exhaust gas collection line, while at least one cylinder of a cylinde...

An internal voltage generating circuit includes a first detector that compares an internal voltage and a first reference voltage to output a first detection signal. A second detector compares a supply voltage and a second reference voltage to output a second detection signal. A loop selection oscillator performs an oscillation operation in response to the first detection signal, selects a first loop or a second loop for performing the oscillation operation in response to the second detection sig...

In general, the invention is directed to a patient programmer for an implantable medical device. The patient programmer may include one or more of a variety of features that may enhance performance, support mobility and compactness, or promote patient convenience. For example, the patient programmer may include an internal antenna for RF telemetry with the implantable medical device. The internal antenna may have a loop-like structure that defines a central aperture. A battery bay may extend at ...

A pipe cutter is designed for cutting a pipe from the inside by insertion of the pipe cutter through an open end of the pipe. The pipe cutter includes an elongated hollow sleeve with first and second ends in which an elongated shaft which is longer than the hollow sleeve is located for rotation. One end of the elongated shaft is adapted for connection to a source of rotational power; and the lower or opposite end of the elongated shaft is attached to a rotary saw blade. A centering housing is lo...
