Title: Voice decoding circuit having error correcting function
Inventor: MATSUMURA NAOMI
IPC: G10L19/005
Filed: 1987-07-17
Abstract: PURPOSE: To minimize deterioration of an output speech signal even if a parity error occurs by outputting a linear predictive decoded signal as the output speech signal in the case of the parity error. CONSTITUTION: A parity error check unit 3 checks whether or not a parity error occurs to an input digital signal 1 as input data in a transmission process. A comparator 5 compares the input digital signal 1 with the output of a linear predictive decoder 2 to check whether or not an error other than the parity error occurs in the transmission process. A selector 4 performs switching to the linear predictive decoded signal outputted previously from the linear predictive decoder 2 and outputting it as an output speech signal 6 once it is judged that the error occurs from the output of the comparator 5. Consequently, the signal outputted from the linear predictive decoder 2 becomes nearly equal to an error-free input digital signal 1 at present time and deterioration of the output speech signal 6 can be minimized.

Abstract: PROBLEM TO BE SOLVED: To enable the printing to be performed by adding specific information which is appropriate to a cassette incorporating a printing medium or the printing medium itself, in the printing device which prints an image on the printing medium built in the cassette such as a tape printer. SOLUTION: Identification information complying with the kind of a tape T stored in a cassette 41 is determined by detecting an identification part 41a provided in the cassette 41 using a cassette sensor 34. Further character string information, indicating the material quality and properties of the tape T, which is previously stored in an additional data storage region corresponding to each of sets of identification information, is read.

Abstract: PROBLEM TO BE SOLVED: To freely select laws of motion securing the minimum acceleration for the oscillation of a sheet receiving device by guiding printed sheets on a track deviated from the surface of a storage drum behind a common point of tangency of the storage drum and a reversing drum. SOLUTION: In the both-side printing operation, a printed sheet 8 is guided on a track deviated from the surface of an impression drum 4 after a paper gripper 7 is released, and the rear end of the sheet 8 is picked at a point of tangency t1:4 by a sheet receiving device 2 of a reversing drum 1 formed as a suction device. After that, the suction device 2 and the gripper oscillate and come closer to each other as publicly known, and the printed sheet 8 is brought from the suction device 2 to the gripper 3. After the gripper 3 oscillates and is separated, the printed sheet 8 moves forward with the rear end in front, reversed and transported continuously. Therefore, laws of motion and the separation angle can be selected according to conditions regardless of the relations between each other.

These magnets are so arranged that the adjacent opposite surfaces of the first magnets are of the same pole and that the second magnets are of the same pole as the poles of the first magnets to which the drum 1 side is adjacent. The magnetic fluxes generated from the N pole of the second magnets are, therefore, penetrated through the drum 1 and are admitted into the S pole of the second magnets.  The magnetic fluxes generated from the second magnets are effectively taken outside. The rotating direction of a magnet rotor 4 is made reverse from the progressing direction of the conveyor, by which the conductive magnetic metallic piece 15 are made to fly forward.

IPC: H01L21/60
Filed: 1981-11-05
Abstract: PURPOSE:To form a normal wire loop by jetting air in a part of a time while a capillary is moving from a first bonding point to a second bonding point. CONSTITUTION:After a ball 1a is formed by a torch 4, air is jetted to wire 1 and the ball 1a is fastened to the tip of a capillary 3. The air jetting is stopped between (c) and (d). Subsequently, by the operations (d)-(g) wire is spread between a first bonding point 5 and a second bonding point 6 to form a wire loop, whereas the air jetting is started for (e)-(f). When the capillary 3 starts bonding for the point 6 at (g), the air jetting is stopped. Since the air jetting is carried out between (e)-(f), the wire loop can be prevented from becoming low even if the quantity of flowing air is large, and proper wire loop is formed.

Filed: 1996-07-08
Abstract: PROBLEM TO BE SOLVED: To effectively prevent moire caused by the interference of a cycle mark with an image pattern on an electrostatic latent image in the case of changing the circumferential speed of an intermediate transfer belt. SOLUTION: Toner images are formed on a photoreceptor drum 1, successively primarily transferred to the intermediate transfer belt 5a so that the toner images of four colors are superposed on the surface of the belt 5a, and secondarily transferred to recording material P altogether.

There is possibility that the moire caused by the interference of the cycle mark with the image pattern on the electrostatic latent image is derived when the moving speed of the drum 1 is changed.  Then, a high-voltage power source 11 is controlled by the controller 10 so as to properly control the electrification frequency of AC voltage out of electrification bias applied on a transfer roller 2, whereby the moire is prevented.
