Title: Speech coding and decoding device
Inventor: MINAMI SHIGENOBU
IPC: G10L19/00
Filed: 1988-03-18
Abstract: PURPOSE:To easily select and determine a coding system without using recognition information by selecting the speech coding and decoding circuit with which the decoding output signals most markedly showing speech characteristics is obtainable from plural speech coding and decoding circuits. CONSTITUTION:A codec 6a to which the 1st coding system is applied and a codec 6b to which the 2nd coding system is applied are provided in parallel. A rule detector 10 is inputted with the decoding signal output of the speech information decoded by the respective codecs 6a, 6b and detects the speech characteristics. The detector decides whether the correct decoding with the speech coding signal is executed in accordance with the detected speech characteristics or not; thereafter, the detector executes control by selecting switches SW1, SW2 so as to use the codecs 6a, 6b from which the decoding outputs most markedly showing the speech characteristics are obtd. The need for the intricate control such as communication of the recognition information to indicate the kind of the coding system prior to the communication and control of the recognition information is thereby eliminated and the simple and efficient coding communication of the speech information by the various coding systems is enabled.

IPC: H01F10/20
Filed: 1985-03-28
Abstract: PURPOSE:To produce a ferrite film in high productivity, by adsorbing an aqueous solution containing ferrous ion and an anion such as acetate group to a solid surface, supplying oxygen to the system, and carrying out the ferrite crystallization reaction on the solid surface. CONSTITUTION:The rotary disk 11 is placed in the outer cylinder 12, and a solid 15 having adsorption activity is fixed to the ceramic heater 5 attached to the disk 11. An aqueous solution containing at least ferrous ion as a metallic ion and an anion such as acetate group, carbonate group, etc., (e.g. aqueous solution of ferrous ammonium acetate) is dripped continuously through the inlet pipe 1 onto the solid 15 to keep the surface of the solid 15 in a state wet with a thin liquid film. N2 gas and O2 gas are introduced through the gas- introducing pipes 8, 9. The oxidization of ferrous hydroxide ion or the ion and other metal hydroxide ion takes place by this process, and a ferrite film is formed on the solid 15 by the resultant ferrite crystallization reaction.

Filed: 1997-03-18
Abstract: PROBLEM TO BE SOLVED: To indirectly on/off-control power, to suppress unpleasant popping sound and to securely protect output shortcircuit by suppressing the change speed of bias voltage and holding a protection circuit to an operation state until bias voltage becomes lower than an active level where a power amplifier circuit is operated. SOLUTION: When a standby setting signal Sin in a standby setting terminal P4 is switched from an L level where an audio power amplifier circuit 2 is set to a non-operation state to an H level where the circuit is set to the operation state, a bias circuit 3 and the protection circuit 4 start to the operation state from the non-operation state in response. The change speed of bias voltage VB given from the bias circuit 3 to the power amplifier circuit 2 is suppressed by a transition suppression circuit 31 and the operation start and the operation stop of the power amplifier circuit 2 are slightly delayed compared to those of the protection circuit 4. The destruction of the power amplifier circuit 2 owing to wiring shortcircuit can securely be prevented while the sudden transient change generating unpleasant popping sound is suppressed.
