摘要:
An object of the present invention is to provide a sensor system which can effect local communications suitable for exchanging information to avoid collisions between mobile robots. The sensor system also prevents collisions between the mobile robots and obstacles. The system is well-suited for a multi-robot environment where multiple mobile robots operate. The system includes infrared signal transmitters installed in each of the multiple mobile robots for sending transmission data via infrared signals. The system further includes infrared signal receivers installed in each of the multiple mobile robots for receiving the transmission data sent by the infrared signal transmitters. Each mobile robot includes a control unit. The control unit prepares transmission information which includes mobile robot identification information unique to the mobile robot. The transmission information is included in the transmission data sent from the infrared signal transmitter. The control unit also extracts transmission information which is received by the infrared signal receiver.

A data carrier system allows data to be transmitted and received. The data is transmitted using weak radio waves of suitable frequencies, such as frequencies in a high frequency band (HF) or a very high frequency band (VHF). The transmitters and receivers need not physically contact each other, be located in any particular position, or be oriented in any particular direction. The data carrier system does not suffer deficiencies in electric power supply, and therefore there exists no need to exchange batteries. Individual transmitters and receivers are positively discriminated one from another. The receivers are in the form of a plurality of tags. The transmitters are in the form of a plurality of reader-writers. Both are controlled by microcomputers, and each tag is equipped with a secondary battery as the power source.

The invention improves the thermal conductivity of the material powder to be fired and also makes it possible to produce an amorphous magnetically soft body within a shortened period of time. The amorphous magnetically soft body is produced by preforming the material powder into a body first, and heating the preformed body without pressing. Stated more specifically, an amorphous magnetically soft body is produced from a material powder comprising a powder of an amorphous magnetically soft alloy, a glass having a softening point lower than the crystallization starting temperature of the alloy and a binding resin, by pressing the material powder in a preforming die to prepare a preformed body by the binding property of the resin, and firing the preformed body without pressing at a temperature higher than the softening point of the glass and lower than the crystallization starting temperature of the alloy to join the particles of the alloy with the glass.

The invention provides a thermoelectric element produced by placing a powder of thermoelectric material over an electrode plate first and then an electrode plate over the power to form superposed layers, and thereafter sintering the powder with a pressure applied thereto perpendicular to the superposed layers. The electrode plates and the thermoelectric material are joined into an integral assembly before fabricating a thermoelectric module. The invention provides a thermoelectric module which is produced by arranging p-type thermoelectric elements and n-type thermoelectric elements alternately in a row at a predetermined interval, each of the elements comprising a thermoelectric material provided between and joined to a pair of opposed electrode plates, and interconnecting pairs of spaced adjacent upper electrode plates and pairs of spaced adjacent lower electrode plates alternately by brazing to electrically connect the p-type and n-type thermoelectric elements in series. Another thermoelectric module of the invention is fabricated by preparing a plurality of submodules each comprising p-type thermoelectric elements and n-type thermoelectric elements arranged alternately in an elongated row and electrically connected in series through electrode plates, arranging the submodules side by side suitably, and brazing the electrode plate of the p-type thermoelectric element at an end position of each submodule to the electrode plate of the n-type thermoelectric element at a corresponding end position of another submodule adjacent to the submodule so as to electrically connect the plurality of submodules in series.

A satellite radio wave capturing method of a GPS receiver, in which an offset value of an oscillator of the GPS receiver is calculated by subtracting a Doppler frequency deviation of the first captured satellite radio wave from an actual received frequency of the first captured satellite radio wave, and with respect to the second and subsequent satellite radio waves to be captured, the search center frequencies are reset by using the calculated offset value, and an oscillating frequency of the oscillator is changed by using the set search center frequency as a reference, thereby capturing the radio wave of the target satellite. The elapsed time which is required from the power-OFF at the preceding position measurement by the GPS receiver to the power-ON at the present position measurement is measured. In accordance with the duration of the measured elapsed time, a determination is made to see whether or not the offset value of the oscillator which has been obtained at the preceding position measurement and stored in a memory in the GPS receiver is used as an offset value of the oscillator at the present position measurement. The mean value of a plurality of offset values obtained within a predetermined time just after the power-ON of the GPS receiver is calculated and stored. At the next power-ON of the receiver, the stored mean value of the offset values is used as an initial offset value at the start of the position measurement.

A mobile terminal apparatus includes a first housing provided with a display, a second housing provided with a keyboard, and a slide holding mechanism including a rail unit provided in the first housing and including rail parts extending in a sliding direction, arm members, rotation-slide connection members which include rotation shafts separated from each other in the sliding direction and which connect one end portions of the arm members to the rail parts, and rotation connection members which include rotation shafts separated from each other in the sliding direction and which connect the other end portions of the arm members to the second housing. The slide holding mechanism holds the housings such that the housings are slidable between a closed state in which the housings substantially entirely overlap and an open state in which the display unit and the keyboard are positioned on substantially the same plane.
