A sync detection circuit detects a standard signal which is a signal having V-sync signals with a predetermined repetition period, a non-standard signal which is a signal having V-sync signals with the repetition period other than the predetermined repetition period, and a signal absent condition which occurs when the broadcasting is finished. The sync detection circuit includes a V-sync separator for separating V-sync signals, a counter for counting the predetermined repetition period in relation to each of the V-sync signals and for producing a count-up signal upon counting the predetermined repetition period, and a phase comparator for comparing the phase of the count-up signal with the phase of a V-sync signal and for producing a first level signal, representing the receipt of the standard signal, when the compared signals have the same phase, and a second level signal, representing the receipt of the nonstandard signal, when the compared signals have the different phase. The counter also counts a predetermined time period, which is greater than the predetermined repetition period, in relation to the V-sync signal and for producing a time-up signal upon counting the predetermined time period, and a condition detector for detecting the signal absent condition when no V-sync signal appears before the time-up signal is produced.

The present invention relates to a vertical synchronizing pulse generating circuit in a television receiver, wherein a vertical synchronizing separation circuit (VS) is so composed not as to directly integrate pulses sequentially outputted from a composite synchronizing separation circuit, but as to integrate a small amount of electric current outputted according to the sequentially outputted pulses. Accordingly, it is possible to reduce the capacity of a capacitor (22) used for the integration and at the same time, it is possible to incorporate the capacitor in an integrated circuit, Thus, it is possible to decrease the number of pins provided to the integrated circuit. Furthermore, the small amount of electric current can be regulated according to the electric current flowing through an externally connected load (28).

A search system has a management device that stores compound data and a searcher device. The management device defines a similarity between query sequence data q representing a substructure or property of a substance that is input as a search condition at the searcher device and sequence data pi (i=1, 2, . . . , m) for substances stored in the database by means of a score T that takes a non-negative value when a Tversky index Si is greater than or equal to a threshold value θn/θd (where θn and θd are natural numbers that satisfy θn≦θd, calculates an encrypted value of the score T while the query sequence q is maintained in an encrypted state, and returns the encrypted value to the searcher device to thereby disclose information regarding whether or not similar compounds are present in the database while in a confidential state.

摘要:
The vertical drive pulse generator comprises a gate (59) passing a vertical synchronizing signal included in received video signals in response to a control signal, a counter (60; 360) counting a clock signal (CL) of 2f.sub.H (f.sub.H : a frequency of a horizontal synchronizing signal) to generate a plurality of timing signals, a 50/60 decider (65; 365) deciding whether the vertical synchronizing signal from the gate is of the NTSC or the PAL system and a synchronization decoder (66; 366) detecting whether the counter is reset in response to the vertical synchronizing signal passed through the gate or by a timing signal outputted by itself. One of the timing signals from the counter is selected in response to the outputs of the 50/60 decider (365; 65) and the synchronization detector (66; 366) and applied to the gate, thereby to make the gate pass a signal only when the control signal is received. When the 50/60 decider indicates that the arriving vertical synchronizing signal is of the NTSC system, the gate circuit (67; 367) opens during a period of 224 H to 296 H (H: a horizontal scanning period), while detecting the PAL system to open the gate during a period of 268 H to 356 H. when a step-out detection circuit (66; 366) detects a step-out state, the gate opens during 224 H to 356 H. The vertical drive pulse generator further comprises a phase comparator (422) which selects and generates a signal for defining a gate period of either 260.5 H to 264 H for NTSC system or 310.5 H to 314 H for PAL system.
