Title: Input terminal
Inventor: NAIKI HIDEO
IPC: G10K9/122
Filed: 2002-11-14
Abstract: <P>PROBLEM TO BE SOLVED: To solve a problem that it is necessary to consider both ways of using, specially, an input terminal used for password code input, holding by hand and on a desk since, when a sound radiation hole is bored in a smooth surface or projection part, the hand of an operator closes the sound radiation hole and then buzzer sound volume becomes too small to transmit sufficient information to the operator.  <P>SOLUTION: A recessed part 4 is provided with a sound radiation hole 5 for outputting a buzzer sound from a sounding body 2 and a step part 3 is arranged around it. Consequently, the sound radiation hole 5 is not closed neither with a mount base 6 where the input terminal 1 is set nor by the hand 8 of the person who operates the terminal and then the buzzer sound is easy to hear.  <P>COPYRIGHT: (C)2004,JPO

Title: Automatic gain control instrument
Inventor: TERASAWA AKIRA
IPC: H03G3/30
Filed: 2002-11-18
Abstract: <P>PROBLEM TO BE SOLVED: To perform gain control which keeps an output signal level constant even if the input signal level variation is large.  <P>SOLUTION: A gain function selection part 4 selects a gain function F1 if a long time average value is relatively small, selects gain function F3 if it is relatively large, and selects a gain function F2 if it is relatively in an intermediate level. A gain calculation part 5 inserts a short time average value in the input level of the selected gain function Fi, and calculates the output level, and calculates the gain by dividing the output level with the input level (short time average value). Therefore, comparing to the conventional example which performs gain control only by a single gain function, the gain control is possible to keep the output signal level constant in case that level variation of the input signal is large.  <P>COPYRIGHT: (C)2004,JPO
