Abstract:
A radio receiver (1) having a synthesizer-type receiving circuit, in which the received broadcast signal is determined by varying a frequency-dividing ratio in a phase-locked loop, is provided with a display (10i) which shows in respective areas (12A-12J) of a tabular format the names of various geographic regions and of broadcasting stations that can be received in the respective geographic regions, and with a memory having addresses for storing data corresponding to frequencies needed for the reception of respective broadcasting stations receivable in the various geographic regions. A signal forming circuit, for example, responsive to coded information (11A-11D) on the display, provides signals indicating respective geographic regions whose names are selectively displayed, and channel-selection switches, which are desirably positionally related to respective areas of the tabular format of the display, are selectively actuable for cooperation with the signals from the signal forming circuit in causing a microcomputer to read data stored at respective addresses of the memory and to determine the frequency-dividing ratio from such data.

Abstract:
PROBLEM TO BE SOLVED: To increase an A-D conversion processing speed and reduce power consumption while suppressing the increase of a circuit area, in a solid-state imaging apparatus employing a reference signal comparison type A-D conversion system. SOLUTION: Two kinds of reference signals Vslop which are changed stepwise by 2LSB and have steps of 1LSB are prepared. A reference signal Vslop_2 having a lower level and a pixel signal Vx are compared to hold a count value T during the inversion of a comparison pulse COMP. The reference signal Vslop_2 is switched to a reference signal Vslop_1 to compare the reference signal Vslop_1 and the pixel signal voltage Vx, and the held count value T is corrected on the basis of the comparison result to settle pixel data D. The pixel data D are 2T-1 in the case of (a pixel signal voltage Vxα)>(the reference signal Vslop_1(T)) and 2T in the case of (the pixel signal voltage Vxα) COPYRIGHT: (C)2008,JPO&INPIT
Abstract:
PROBLEM TO BE SOLVED: To avoid an overcharged or an overdischarged state of a secondary battery by a method wherein, when the secondary battery is overcharged or overdischarged, the secondary battery is discharged or charged through an electric circuit. SOLUTION: In a protection circuit 11, the emitter of a P-N-P transistor Tr1 of an on-set circuit 12 is connected to a control circuit 13 and the collector of the P-N-P transistor Tr1 is connected to an electric circuit with which the cathode of a secondary battery BT is connected to a switch circuit 8. Thus, in the protection circuit 11, by supplying pulse control signals S5 continuously from a signal input terminal T, the on-set circuit 12 is kept on and hence the control circuit 13 can reset the switch circuit 8 through a drive circuit 7. With this constitution, the protection circuit 11 can charge or discharge the secondary battery BT by putting the transistors FET1 and FET2 of the switch circuit 8 into continuity the control circuit 13.

CONSTITUTION:A disk reproduction section 59 reproduces a voice program name being a track name located to a tree structure recorded on a disk 50 and sends the tree structure via a telephone line via a system control section 55. Dial information in response to the transmission is detected by an incoming call detection circuit section 52, the disk 50 is reproduced corresponding to the program to be sent via the control section 55 depending on the detection result and sent through a line 36. Through this constitution, it is not required to set manually the tree structure and a music is selected and played at a high speed accurately.
