Abstract: The present invention provides a compound represented by the following chemical formula (I); a tautomer or stereoisomer of the compound; or a salt of the compound, the tautomer, or the stereoisomer. In the chemical formula (I), R1 and R2 are each a Group 1 element or a protecting group of an amino group and may be identical to or different from each other, or alternatively, R1 and R2 together may form a protecting group of an amino group. R3 is a Group 1 element or a protecting group of a hydroxy group. R4 is a Group 1 element or —PR5R6R7R8 (R5, R6, R7, and R8 are each a Group 1 element, a lone electron pair, a Group 16 element, a Group 17 element, or a protecting group of a phosphorus atom, and may be identical to or different from each other). J is a hydrogen atom or an arbitrary atomic group, A is a hydrogen atom, a hydroxy group, an alkyl group, an aralkyl group, an alkoxy group, an electron-withdrawing group, a silylene group, or a sulfide group, or alternatively, J and A together may form a linker.

Abstract: A cordless phone base unit includes a storage unit that stores a phone number of other party in association with a name of the other party in a registration table, a reading unit that reads the name of the other party from the storage unit based on a received phone number of the other party, a language selection unit that selects a language corresponding to the read name of the other party, and a voice data generating unit that converts the read name of the other party into voice data in the selected language and outputs the voice data.

Abstract: This invention discloses a multi-track recorded information regenerating system which regenerates signals recorded on a plurality of tracks and which composes and demodulates these recorded signals so as to obtain a read output signal. The characteristic feature of the present invention is to provide a delay circuit, which delays the regenerated signals in each track. Three signals are synthesized; that is, a first signal is synthesized from two regenerated signals from two tracks, and a second and a third signal are synthesized from one of the regenerated signals from two tracks and one of the outputs of the delay circuit. These synthesized signals are detected by an error checking circuit to determine whether or not said synthesized signals represent correct information recorded on the magnetic track, and the synthesized signal having the correct information is used as the read output of the multi-track recording system.
