    摘要: A bidirectional switch circuit includes a parallel circuit of two unidirectional switch devices which are connected between a first and a second external current terminals. These switch devices are arranged to be reverse to each other in their current-forwarding direction. The switch devices are electrically biased by a single power supply unit, and turn on alternately in accordance with the potential difference between the external terminals. Each switch device may be an insulated gate bipolar transistor (IGBT), which is driven by a bias voltage generator including a resistor. A current flow controller is connected between the power supply unit and the IGBTs, for selectively supplying a control current to one of the IGBTs. A return-current path selector is connected between the external terminals, and has an output connected to the power supply unit through a return path line. The selector automatically performs a return-path changeover operation for a return-current of one of the switch devices being presently turned on.

    摘要: An apparatus for detecting the collision of objects including a moving object includes a face information memory for storing face information describing the surfaces of each object; hierarchical sphere model generator for modeling the surfaces of each object by hierarchically covering the surfaces with spheres having various radii on the basis of the face information; sphere model memory for storing the positions of the modeled spheres generated; sphere position updater for updating the position of each modeled sphere having various radii with respect to the moving object and outputting the updated position; and sphere collision computer for executing procedures in which mutually colliding spheres are detected on the basis of the positions of the modeled spheres concerning two of the objects generated at an arbitrary time and stored in the sphere model memory and colliding spheres among spheres belonging to the mutually colliding spheres and having a smaller radius are further detected with respect to only the spheres determined to collide with each other, and for determining the collision of the two objects with each other when finally mutually colliding spheres having the smallest radius are present. The procedures are executed hierarchically and consecutively starting with spheres having a large radius toward spheres having a smaller radius.

    摘要: A drive circuit for a wire dot print head including a driving coil, a print lever attracted by the coil in a first direction, a spring for biasing the print lever in a second opposite direction and a damper includes a DC power source connected to a first end of the driving coil. A transistor is connected to the second end of the driving coil. An output circuit provides a gated output to the transistor. The output circuit receives as a first input a print data signal and as a second input a signal from a reference timing signal generator. The reference timing signal generator includes a drive pulse signal generator which provides an output in response to a print timing pulse which causes the output circuit to provide an output for the driving coil to attract the print lever. The reference timing signal generator also includes a brake pulse signal generator which provides an output when the print head temperature falls outside of a predetermined range after a predetermined interval so that current is caused to flow through the driving coil when the print lever is moving in the second direction and the print head temperature falls outside of the temperature range.

    摘要: In an automatic call transfer system for use in carrying out transfer of a terminating call from one of telephone sets (T) to another through an exchange (11), a person identification number (ID) is assigned to each of persons movable in a limited area and is generated from a transmitter (TX) conveyed by each person. The limited area is divided into a plurality of zones (Z) which are defined by receivers (RX) connected through subscriber lines to the exchange, respectively, and which include at least one of the telephone sets, respectively. The person identification number is produced from a transmitter (TX) conveyed by each person and is received by a selected one of the receivers in the zone for the selected receiver to be sent through one of the subscriber lines (L) to the exchange. A line number of the one subscriber line is memorized in a memory of the exchange in correspondence to the person identification number and is changed as each person moves in the limited area. Responsive to the terminating call carrying the person identification number, the exchange searches the memory to detect the line number memorized therein and to transfer the terminating call to one of the telephone sets indicated by the memorized line number.

    摘要: An exhaust purifying system for a multi-cylinder four-cycle internal combustion engine operating on an intake mixture leaner than stoichiometric employs first preliminary reaction chambers receiving exhaust gases from ports connected to cylinders having successive firing order. The exhaust gases are then delivered from said first preliminary reaction chambers to a single second preliminary reaction chamber and then to a catalytic reaction chamber containing oxidative catalysts of base metals, and then finally to an oxidative reaction chamber. The intake mixture for the engine is heated from exhaust gases in the oxidative reaction chamber. This particular succession of chambers causes the temperature of the exhaust gases to increase to above 800.degree. C.
