Title: Character recognizer
Inventor: SONE HIROFUMI
IPC: G06K9/48
Filed: 1984-12-18
Abstract: PURPOSE:To obtain easily the stable feature quantity having high resistance to the position shift of a character pattern and to improve the character recognizing accuracy, by using the direction exponent series extracted out of a contour part of the character pattern and the emerging frequency of the projection/ recess degree as the feature quantity. CONSTITUTION:A direction exponent series extracting part 13 tracks the contour part of a character pattern after preprocessing for extraction of eight direction exponent series. A projection/recess degree extracting part 14 extracts the projection/recess degree for each point of the contour part. An emerging frequency calculating part 15 calculates the emerging frequency of the direction exponent series and the projection/recess degree for each of small rectangular areas divided to secure mutual overlap. A discrimination processing part 16 defines a category where the distance between a standard pattern of the emerging frequency and an input pattern is minimum from the maximum and minimum allowance values in the form of the recognition result.

Title: A/d converter circuit
Inventor: MATSUYAMA HIDETO
IPC: H04N7/081
Filed: 1995-10-16
Abstract: PROBLEM TO BE SOLVED: To reduce the number of ports in the case of circuit integration of part or all without the need of provision of a reference level signal different from the case of using a comparator because a video signal switched to a different level is sliced by an inverter circuit. SOLUTION: A luminance signal Y received from a terminal S1 is clamped according to a pedestal clamp pulse given at first to an analog switch 36, and a level of a video signal is switched into plural levels by resistors R7 to R12 . The video signals whose levels are switched are given to the same inverter circuits 40 to 46, in which the video signals are sliced at a prescribed level. Thus, the video signals are sliced by different levels and the result is outputted as a high level or a low level signal from each of the inverter circuits 40 to 46.

Title: Graph expression method and device for graph unification
Inventor: NIINO HIROYUKI
IPC: G06F17/28
Filed: 1991-09-19
Abstract: PURPOSE:To improve processing efficiency for unifying graphs by managing the nodes of the graphs in a node data base in a wide area by means of ID numbers and sharing and using the nodes in the input graphs as the graph of a result which is unified. CONSTITUTION:A basic unifying means unifies the ID numbers of the root nodes of the two inputted graphs by referring to the node data base 3 holding the ID numbers of the nodes and node information, a new node ID data base 4 holding the ID number of the new node generated during a unifying processing, and the data base 5 for node which is previously unified and holding the ID numbers before and after the processing for unifying. When the node which is previously unified is unified again, the result is not reflected on a previous unifying result. A master node alteration means 2 checks whether the node of the acyclic place of the graph is altered or not and corrects the required node. Thus, a copy operation is avoided and the efficiency of the processing can be improved.

Abstract: PURPOSE:To prevent a product from damage improved in its sorting ability by successively providing a downward facing tilt fixed conveying surface, providing two or more opening and closing cover-provided dropping ports, to be lined with a carrying conveyor and arranging a chute between the dropping port and an introducing conveyer. CONSTITUTION:A sack product, conveyed by a transport conveyer 3, slides dropping on a fixed conveying surface of a sorter 10 from a tilt plate 11. The first sack product drops onto a chute 13a from an opening and closing cover 12a with its cover open, being introduced to an introducing conveyer 4. When this dropping is detected by a sensor, (not shown in fig.) the opening and closing cover 12a closes. Accordingly, the second product moves sliding to the second opening and closing cover 12b, passing through the opening and closing cover 12b and a chute 13b and dropping onto the introducing conveyer 4. Simultaneously the opening and closing cover 12b closes. Repeating this action, the product is supplied to an opening and closing cover 12d, returning to the first opening and closing cover 12a, the action is similarly repeated. Thus sorting ability can be improved.

Filed: 1993-09-30
Abstract: PURPOSE:To obtain the easy-to-sing KARAOKE reproducing machine by making the key of the accompaniment sound of the KARAOKE reproducing machine follow up a singer's singing voice. CONSTITUTION:The singer's singing voice gathered by a microphone 1 is amplified by an amplifier 2, and then amplified by an adder 3 together with the accompaniment sound and sent to a speaker 4. To prevent the accompaniment sound generated by reproducing a disk 5 on a player 6 from leaking to the microphone 1 through a key control, the adder 3, and the speaker 4, a subtracter 8 subtracts the accompaniment sound from the singing voice. Then, the accompaniment sound and singing voice have their pitches detected by specific methods through a singing voice pitch detector 9 and an accompaniment sound pitch detector 10, respectively. The pitch periods of the accompaniment sound and singer's singing voice are detected and compared with each other, and the period of the readout clock of the key control of the KARAOKE reproducing machine is varied so as to match the pitch of the singing voice of the singer. Thus, the key of the accompaniment sound is made to follow up the singer's singing voice.
