Filed: 1989-10-14
Abstract: PURPOSE:To obtain a focusing error signal not to be diffracted by a guide groove by forming the focusing error signal only by reflected light from a land when a condenser spot crosses the guide groove by utilizing the fact that the condenser spot on the land is not widely diffracted like the condenser spot on the guide groove. CONSTITUTION:An information carrier 6 composed of a guide groove 8 and a land 26 is irradiated with a condenser spot 7 and the output waveform of an adder amplifier 21 is changed by diffraction when crossing the guide groove 8. Next, the output waveform is compared with a certain threshold value Vth by a comparator 22 and it is discriminated whether the spot is on the guide groove 8 or the land 26. In such a case, when the spot 7 is on the land 26, an 'H' level is set and when the spot 7 is on the groove 8, an 'L' level is set. The pulse of certain fixed width T is generated from a pulse generator 23 synchronously with rise from 'L' to 'H' and a focusing error signal 17 of the spot 7 is outputted from a differential amplifier 16. Afterwards, only the output of the land 26 is held by an S/H circuit 24 and the error signal is obtained without ripple 18 caused by the groove 8.

Abstract: PROBLEM TO BE SOLVED: To prolong the aggregate service utilization time of an auction participant. SOLUTION: To an article which is a target of auction, a start price, an estimate price band and a lower limit price are preset. A server device for providing the service of auction starts the service from the set start prize and lowers the price to be presented for every lapse of prescribed time. The width of price-down is made into first scaling when the price presented at present is higher than the estimate price, into second scaling (smaller than first scaling) when the present price is within the range of the estimate price band and made into third scaling (smaller than second scaling) when the present price is lower than the estimate price band so that the curve of price-down can be made smooth with the passage of time.  During this operation, when information showing the will to purchase the relevant article is transmitted through a network to the server device, a successful bid is determined with the price presented at that time and the auction is ended.
