Title: Device and method for embedding digital watermark data, transmitting method, recording medium and device and method for readin the watermark data
Inventor: NAITO JOJI
IPC: G10L25/51
Filed: 1999-09-30
Abstract: PROBLEM TO BE SOLVED: To permit only watermark data from not being removed efficiently as long as a password is unknown by enciphering watermark data, to which an error detecting code is added and embedding enciphered watermark data by means of a different embedding method. SOLUTION: Watermark data is transmitted to an enciphering mans 2, after adding the error detecting code to it by an error detecting code adding means 1 and enciphered, based on the password which is inputted by a user. Enciphered watermark data after adding the error detecting code is embedded into contents data, based on the method selected by a selector 3 among watermark embedding methods which are multiply defined by N pieces of encoders 4. Thus, contents data where watermark data are embedded are distributed by a recording medium 100 and transmitted by a transmitting means 102.

Abstract: PROBLEM TO BE SOLVED: To provide a hot water supply apparatus capable of preventing the temperature of water in a heat-exchanger from being increased to a value partially higher than an upper limit temperature even when heating is effected with a faucet being not opened. SOLUTION: When water in a heat-exchanger 14 is heated with a hot water supply faucet being not opened, by effecting intermittent combustion of a burner 12 for hot water supply a plurality of times, the temperature of water in the internal whole of the heat-exchanger 14 is heated to a target temperature.

Further, During a time in which combustion is stopped, temperature distribution at the internal part of the heat-exchanger 14 is uniformized.  As noted above, since heating to a target temperature is intermittently effected in division a plurality of times, the water temperature of the whole of the internal part of the heat-exchanger 14 is increased to a target temperature without exceeding an upper limit temperature by a water temperature in a spot wherein direct heating is effected by the burner 12 for hot water supply.
