Title: Sound reproducer
Inventor: OHASHI TOSHIHIKO
IPC: H04R3/00
Filed: 1998-03-25
Abstract: PROBLEM TO BE SOLVED: To perform the stable feedback and to secure the feedback effects in a wide band by correcting the output side of a sensor, which detects the reproduced signals at a correction part and connecting the corrected output side to one of both input sides of a subtracter. SOLUTION: The output side of a sensor 4, which is placed near a speaker 3, is connected to an A/D conversion part 5, a signal processing part 6 and a D/A conversion part 7. The output side of the part 7 is connected to one of both input terminals of a subtracter 1. A correction part consists of the parts 5, 6 and 7. As the signal of the sensor 4 that detected the output of the loudspeaker 3 has its limited feedback degree, the phase characteristic is corrected by the correction part without very much affecting the amplitude characteristic. Thus, the phase shift of a feedback signal is suppressed by the correction part, and accordingly the stable feedback operations are secured in a wide band. As a result, the distortions and the sound pressure frequency characteristic can be improved adequately with respect to the actual reproduced sounds.

IPC: G06K9/62
Filed: 1991-04-10
Abstract: PURPOSE:To collectively display a character string collectively expressing a meaning as a word does when a hand-written graphic is read and recognized as a character string. CONSTITUTION:When a hand-written graphic is inputted from an input section 12, a recognizing section 21 recognizes the graphic as a character and decide its character code and position. A storing section 22 stores the codes and positions of inputted characters and the characters are stored as a character string. A discriminating section 25 refers to a dictionary 24 whenever one character is added to the character string in the section 22 and confirms whether or not the character string is a registered word. When the character string is a registered word, the input character string constituting the word is given to a lining-up section 26 so as to line up the character string for which the positional information associated with each character is collectively displayed.

Filed: 1979-06-21
Abstract: PURPOSE: To provide a combustion device for liquid fuel which makes possible to start combustion quickly and extinguish fire instantaneously by providing a burner inner cylinder of a downwardly divergent shape which is arranged vertically.  
     CONSTITUTION: If the inside of a combustion chamber 8 is purged by a blower 12, an ignition device 14 is actuated and fuel is injected from an atomizing nozzle 10 via a fuel feed pump 11, fine fuel particles carried by primary air blow out from flame holes 6 and are ignited by consecutive spark discharges caused by the ignition device 14. A part of sprayed fuel stays on the concave parts of an end plate 7, but as they are heated by combustion heat, they become to serve as an effective vaporizing surface. Therefore the fuel sprayed onto the concave parts is vaporized immediately and forms gas premixture with primary air. If the apparatus is so arranged that combustion for the maximum rated combustion quantity may be completed with primary air and secondary air, a flame moves to the upstream side as fuel is throttled and a flame is formed at a position where air supply satisfys the set quantity of combustion.

Title: Error detecting system
Inventor: TERAKAWA YASUNARI
IPC: G06F12/16
Filed: 1982-05-10
Abstract: PURPOSE:To reduce the hardware quantity and improve a detection capability compared with a case where an error is detected in parallel, by giving a series CRC operation to the information stored in a storage device to detect an error. CONSTITUTION:An error detection control circuit 3 advances the designation of addresses. At the same time, the read information from an address 0 of a fixed storage device 1 through the final storage address (n) where the error detection information is stored is made into series form successively to perform a CRC (cyclic redundancy check) operation. A CRC operation is given to the error detection information stored in the address (n), and then the address stored in an address counter 2 is turned into an address n+1. Thus the coincidence is obtained with the value of the address stored previously. Then the counter 2 generates an error detection stop signal 16 to discontinue the working of the circuit 3, and at the same time an error detecting circuit 6 is set in an enable state. A CRC output signal 14 is inspected by the circuit 6, and an error display signal 15 showing the result of the inspection is delivered.
