Title: Signal recorder
Inventor: NISHIJIMA TAKEO
IPC: G11B20/10
Filed: 1996-05-21
Abstract: PROBLEM TO BE SOLVED: To provide a signal recorder capable of recording signals for the prescribed time or longer. SOLUTION: The remaining quantity of the recording media in a signal recording section 36 is detected by a residual quantity detecting section 38 and detection signals RM are supplied to a control section 34. The recording time is set by operating sections 18, 40 and a remote controller 45. If the remaining quantity is smaller than the recording time, the information quantity of a video signal DV is decreased by increasing the compression rate of a signal processing section 32 by a control signal CR, by which a recording signal WD is formed. This signal is recorded on the recording medium of the signal recording section 36.  Even if the remaining amt. of the tape and recording time displayed on the display section 20 are insufficient during photographing, the compression rate of the signal processing section 32 is varied by the control signal CR by operating the operating section 18, etc. The recording of the video signal DV more than the prescribed recording time on the recording medium is made possible.

Abstract: PURPOSE:To secure a quick stability for the circuit, by using such AFC circuit that ensures an assured reception during the power supply on and although a drift may occur to the local transmission operation excepting during the time when the power supply is turned on or preset. CONSTITUTION:The delay 10 is given to the voltage rise time for a fixed time when the power supply switch is turned on or preset, and then waveform shaping 12 is given after the differentiation 11. The output of the wave shaping is led to the bias circuit 13 via the capacitor 14 and then supplied to the integral network 16 after the waveform shaping 15 to secure a slow change of the voltage. Then the output of this circuit 16 is supplied to the AFC circuit in the form of the search signal, and thus the AFC lead-in action is carried out within one cycle of the search signal. As a result, the reception is secured during the power supply on even though the local oscillation frequency may have some drift, and at the same time no effect is given to the operations of other circuits excepting the time when the power supply is on or preset. Such AFC circuit can assure a quick stability for the circuit.

Abstract: PURPOSE:To prevent the missetting of data on the commodities that can be sold by reservation and at the same time to reduce the load of clerks by preparing a master file for reserved sale and setting and supplying the reserved sale data on the reserved sale commodities before the starting date of reservation. CONSTITUTION:A disk memory 22 contains a master file for reserved sale and a reservation acceptance file and the reservation control data on the commodities are set and stored into the master file for reserved sale in response to the numbers of each reserved sale commodity. Then said master file is retrieved with input of the reservation data and the starting date of reservation is read out. The reservation is decided impossible if the count value of data of a timepiece circuit 17 does not exceed the starting date of reservation. While the reservation acceptance data is stored in the reservation acceptance file when the count value of the circuit 17 exceeds the starting date of reservation. Thus the data can be set at the master file for reserved sale at an appropriate time point before the starting date of reservation. As a result, the missetting can be avoided for the data on the commodities that can be sold by reservation. At the same time, the load of clerks can be reduced.
