Title: Automatic paper feeder
Inventor: FURUKI ICHIRO
IPC: B65H1/14
Filed: 1996-03-18
Abstract: PROBLEM TO BE SOLVED: To prevent multi-feed and mis-feed of paper sheets by connecting a torque limiter to a separating roller for separating paper sheets picked up by a pick roller one by one, making the separating roller close to and separate from the pick roller, and driving a lifter for lifting up paper sheets and making the paper sheets close to and separate from the pick roller. SOLUTION: A pick roller 3 is driven by a stepping motor to pick up paper sheets 1. A separating roller 4 separates the paper sheets picked up from a paper cassette 2 by the pick roller 3 one by one. A lifter 6 makes the paper sheets 1 close to and separate from the pick roller 3. The separating roller 4 is pressed to the pick roller 3 by a spring 11 to apply contact pressure to the separating part which is the contact point part between the separating roller 4 and the pick roller 3. The separating roller 4 is set to be rotated in the reverse direction to the paper 1 transport direction by a torque limiter 14, so that if two or more paper sheets 1 enter the separating part, the separating roller 4 separates the paper sheets to transport only one paper sheet to the downstream side.

Title: Lock mechanism part of main body part of recording material cassette for thermal transfer printer
Inventor: MITSUISHI TSUTOMU
IPC: B41J17/32
Filed: 1986-03-19
Abstract: PURPOSE:To reduce operational power consumption, by attracting a plunger in a solenoid against the repulsive force of an elastic member when a current is supplied to the solenoid and protruding the same out of the solenoid by the repulsive force of the elastic member at the time of non-supply of a current. CONSTITUTION:When a solenoid 33 is turned ON, a plunger 34 is drawn in the solenoid 33 against the energizing force of a return spring and, when said solenoid 33 is turned OFF, the plunger 34 is protruded from the solenoid by the energizing force of the return spring. The head part of the plunger 34 is made semi-spherical so that the plunger 34 gets under the bottom part of a cassette or a main body part at first even if the cassette or the main body approaches to contact with the plunger 34 so as not to obstruct the movement of the cassette or the main body. When the position of the hole of a housing coincides with that of the head part of the plunger 34, the plunger 34 is protruded by the energizing force of the return spring to be engaged with the hole. By this operation, the movement of the cassette or the main body is stopped and, at the same time, the locking thereof can be performed. Because a time required in drawing the plunger 34 in the solenoid is reduced as a whole, power consumption can be saved.

Title: Speech recognition system
Inventor: ETO KOJI
IPC: G10L15/32
Filed: 1988-03-15
Abstract: PURPOSE:To improve a recognition rate by dividing a word according to no- voice parts in the word, selecting words having the same number of divisions among registered words, and comparing the input word with a reference word and selecting the word with the highest similarity as a 1st candidate. CONSTITUTION:A device consists of a microphone 1, a microphone amplifier 2, a filter bank 2, a microphone processor 4, a RAM 5, a ROM 6, and a display device 7. Then when a word is registered, the word is divided according to no-voice parts in the word to segment voice sections, which are compressed into constant-length parameters to register the word. When the input word is recognized, on the other hand, the word having the same number of divisions is selected among the registered reference words, the input word is compared with the reference words, and it is judged whether or not the word having the highest similarly among comparison results is correct as the 1st candidate; when not, a next candidate is selected and when it is judged that the candidate is correct, the recognition is finished. Thus, the word is divided according to no-voice parts in the word and recognized, so the recognition rate is improved.
