摘要:
A digital broadcast receiver wherein the contents of a plurality of programs are presented prior to the operation of switching (deciding) programs, thereby allowing the user to know the contents of the programs in advance through a simple operation and hence allowing the user to start the viewing of a desired program soon. There are included a display means that receives a data broadcast to display a program; a list display means that displays a list of items of programs; a preview display means that displays, together with the program, preview programs at the same time; a switching means that is linked to the movement of a pointer for the program items and that switches to a target program in accordance with an item selected by use of the pointer with respect to the contents of the preview programs; and a display control means that displays a target preview program in accordance with another item adjacent to the item selected by use of the pointer.

In a radar apparatus, a change in the characteristic of a receiving circuit part is corrected during a normal operation and during an initial adjustment at the shipment, and a change in the characteristic of the receiving circuit part due to a temperature variation caused by an environmental change during an operation or due to an aged deterioration is corrected at any time. In the radar apparatus having a plurality of receiving circuit systems associated with a plurality of receiving antennas, a received channel signal received via an antenna selected by a first switch is used to produce channel signals (ch1,ch2) of the same characteristic, by switching a second switch, which are inputted to the respective receiving circuit systems. The levels and phases of the channel signals as A/D converted are compared to detect a characteristic change. The detection results of the receiving circuit systems are used to correct the characteristics of the receiving circuit systems or those of the A/D converted output signals.

The invention relates to a commodity sale/distribution system. A net order system covering, especially, the ordering of a commodity and acceptance of order at a shop and the delivery of the commodity is disclosed. The net order system for allowing a user to purchase a commodity directly from the commodity provider through the internet comprises the Internet, a client terminal for holding the terminal identification information which is given when the sale of the commodity is permitted by the commodity provider, and a server system for holding the terminal identification information and the commodity sale-concerning information corresponding to the former information. The server system acquires the commodity sale information through the Internet from the client terminal which has been identified by using the terminal identifying information and transmits the corresponding commodity sale-concerning information to the identified client terminal.

In a vehicle control device having a so-called keyless entry system in which a door lock control unit controls a door lock actuator by receiving a signal representing an identification code and transmitted from a transmitter, an internal-combustion engine control unit computes fuel injection quantity and ignition timing from control data stored in a memory in response to detection results inputted from respective detectors, and thereby drives a fuel injection valve and an igniter. The door lock control unit detects whether a theft is attempted on the vehicle, based on the switching states of various switches, and supplies the result of the detection to a constant-voltage circuit in the internal-combustion engine control unit in the form of a code signal; when a theft is detected, power supply to respective circuits in the internal-combustion engine control unit is shut off. Furthermore, the internal-combustion engine control unit checks whether the identification code received by a receiver matches the identification code prestored in the memory, and if they do not coincide, inhibits the internal-combustion engine from starting. Since identification code data that cannot be created in a pseudo manner is inputted to the internal-combustion engine control unit, not a binary signal indicating whether to permit or not permit the starting of the internal-combustion engine, the vehicle can be reliably prevented from being burgled and driven away.

An FM-CW radar device in which an FM modulated wave outputted from a modulated signal generator has a gradient (modulation gradient) of frequency variation with respect to the time axis. The radar device comprises means for controlling the modulated frequency width or modulation period of a modulation signal to vary the modulation gradient. Further comprised is means for detecting a signal component changing with a change of the modulation gradient to discriminate the signal from a target object from other signals. In the case of an FM-CW radar device in which the transmission, the reception, or the transmission and reception are carried out by a time-division ON-OFF control, there is further comprised means for detecting the signal which changes with a change, if made, of the frequency for the ON-OFF control, thereby to discriminate the signal the target object from other signals.

A still object detecting method of a scanning radar comprises gathering peaks having substantially the same frequency out of the ones generated on the basis of a radar signal reflected from a target, judging whether or not the frequency of the is a predetermined value or higher, and judging that the target is an overbridge candidate or an overbridge when the number of the peaks is the predetermined value or more. Moreover, the peak signals of the target of the overbridge candidate are paired to determine the relative velocity of the target thereby to judge the target to be an overbridge when the relative velocity is substantially equal to the velocity of the vehicle equipped with the radar.
