Title: Driving gear for movement
Inventor: FUJIOKA YASUO
IPC: B06B1/06
Filed: 1995-10-12
Abstract: PROBLEM TO BE SOLVED: To obtain a unidirectional or bidirectional rotational driving gear that delivers a large rotational angle, by securing one side of a driving body on an object other than mobile units, and joining a vibrator to the other end so that the width of the driving body will be almost the same as, or slightly smaller than, that of grooves. SOLUTION: Grooves 5 are formed on the rotary shaft 1 of a driving gear, and the grooves 5 are in contact with the side portions 6a, 6b of vibrators 2, 2'. The ends of the vibrators 2, 2' on one side are fixed at fixed portions 4 by means of fixtures. There are vibrators 2, 2' and vibrator elements 3, 3' on both sides of one fixed portion. For driving, oscillating force is applied to the vibrator element 3 (or 3') on one side of the fixed portion 4. If forward rotation is caused when the force is applied to the vibrator element 3, it follows that backward rotation is caused when the force is applied to the vibrator element 3'. In order to transmit oscillation of the oscillators 2, 2', they are joined to the vibrator elements 3, 3' at their surfaces.  When the vibrators are expanded due to the oscillation of the elements 3, 3', frictional force is larger at the side portion 6a than at the side portion 6b. This is also the case when the vibrators are shrunken. This obtains a driving gear wherein the rotary shaft is rotated in the two directions and a large rotational angle is obtained.

Title: Voice recognition system
Inventor: IIDA MASAYUKI
IPC: G10L15/00
Filed: 1987-10-20
Abstract: PURPOSE: To eliminate the need for a storage medium such as a floppy disk by storing the recognition result of a speech recognition device in a sound- recording and reproducing device stored with an input speech to the speech recognition device. CONSTITUTION: A recognition result stored in a storage device 8 is recorded in the sound-recording and reproducing device 2 where the original text is sound-recorded. Consequently, the original text and recognition result can be recorded on the same recording medium, so the management of the original text and recognition result is facilitated. Further, while a sound-recorded document is reproduced and inputted, the recognition result is recorded in the sound- recording and reproducing device 2 to eliminate the need for an external storage medium. Thus, the recognition result like a character code sequence is stored in the sound-recording reproducing device 2 stored with the original text speech, so the need for the storage device such as a floppy disk only for recognition result storage is eliminated to make the device small-sized and low-priced.
