Title: Telephone set
Inventor: MUKUHIRA YASUHIRO
IPC: H04B3/20
Filed: 1995-06-30
Abstract: PURPOSE: To disable a user to listen to a sound giving a feeling of physical disorder with a reverberation sound by providing an input limiting circuit so that when an excessive voice is inputted, it does not exceed the dynamic range of a sidetone amplifier. CONSTITUTION: Even if the excessive voice is inputted through a microphone, a limiter part 4d clips it at a predetermined voltage. For the purpose, a telephone voice is previously distorted by the limiter part 4 and even if distortion is caused by the amplifier of a speech network, no sidetone is heard by the user. Namely, the limiter part 4 operates in response to neither a small input voice nor an intermediate input voice, and operates for a large input voice, and its sent voice is distorted and fed back as a sidetone. The sidetone has a level that does not exceed the dynamic range of the amplifier of the speech network part, so it is inputted as it is to an echo canceler part and canceled by the original voice, so that it never returns to the slave equipment.

Title: Electrolyte for phosphoric acid type fuel battery
Inventor: KAMIIDE MAKOTO
IPC: H01M8/08
Filed: 1989-06-30
Abstract: PURPOSE:To prevent freezing even when operations are suspended under a low temperature environment by incorporating phosphoric acid salt with strong phosphoric acid electrolyte. CONSTITUTION:When phosphoric acid salt which is slightly different in molecular structure is incorporated with strong phosphoric acid, the crystal growth of strong phosphoric acid is so inhibited that its freezing point is lowered. Since phosphoric acid is conjugated salt of strong phosphoric acid negative ions of which are mutually common, phosphoric acid ions which are mutually common, enter into the crystal lattice of phosphoric acid. On the other hand, this permits positive ions of phosphoric acid salt to enter into the crystal lattice in order that electrical balance is kept, the lattice results in failure, and the crystal growth is inhibited so that freezing hardly takes place. Phosphoric acid to be used for electrolyte solution shall, if desirable, be in the amount of 80 to 105% in terms of ortho phosphoric acid. Positive ions forming phosphoric acid shall, if desirable, be alkali metal ions or alkali earth metal ions.
