Title: Both-surface character recognition device
Inventor: SASE SHINJI
IPC: G06K9/20
Filed: 1997-02-28
Abstract: PROBLEM TO BE SOLVED: To make a both-surface read almost as fast as a one-surface read by making a local check and performing an editing process for the contents of a character recognition result individually as to a top and a reverse surface, and storing them on a storage medium. SOLUTION: This device is equipped with a top-surface recognition part 12 and a reverse-surface recognition part 13 which cut necessary images out of an image of the top or reverse surface read by a conveyance scanning part 11 and then perform character recognition independently of each other. The contents of character recognition results of those top-surface recognition part 12 and reverse-surface recognition part 13 are logically checked and edited, and stored on a storage medium such as a hard disk by a top-surface control terminal device 15 and a reverse-surface control terminal device 16.  Namely, this device is equipped with the control terminal devices 15 and 16 which perform the logical check and editing process individually as to the top and reverse surfaces and stores the results on the storage medium, so that characters can be recognized by reading both the surfaces almost as fast as a one-surface read.

Title: Descriptor control system
IPC: G06F13/28
Filed: 1992-03-04
Abstract: PURPOSE:To improve communication line efficiency and communication system efficiency by transferring the tail data block of a received frame first and then transferring the frame header to plural buffer areas.

Title: Gate control circuit for gate turn-off thyristor
Inventor: SATOU MASAYOSHI
IPC: H02M1/06
Filed: 1981-03-31
Abstract: PURPOSE:To prevent the erroneous firing of a gate turn-OFF thyristor (GTO) by closing a switch of a reverse bias circuit having a DC power source and a series circuit of switches during the OFF period of the GTO. CONSTITUTION:Circuits 8, 9, 11 for supplying OFF gate currents to turn a gate turn-OFF thyristor (GTO) and reverse bias circuits 2, 3 for preventing the erroneous operation by reversely biasing the gate at the OFF time of the GTO are provided. When the switch 3 is closed during the OFF period of the GTO, the voltage of a DC power source 2 is applied directly to the GTO. The tail current of the GTO at the turning-OFF time of the GTO and the displacing current at the abruptly changing time of an anode volage flow through the power source 2, but since the impedance of passage is small, the variation in the gate voltage of the GTO is small. Accordingly, the GTO is not erroneously fired due to the application of the positive voltage.

Title: Thermosensitive printing system
Inventor: GOTO TOSHIHIKO
IPC: B41J2/345
Filed: 1985-03-11
Abstract: PURPOSE:To prevent generation of stripes in printing an intermediate tone picture by decreasing the pitch of width scanning more than the print width at main scanning to overlap ends of the printed part and decreasing the density of the overlapped part to make the density of the overlapped part nearly equal to the density of the part without overlapping. CONSTITUTION:The feeding pitch in the width scanning direction is not set to the arranging length (b) of heaters 12 but to a distance (d) shorter than the (b) by n-dot's share of the heater (n is a positive integer). Further, the temperature at heating at a position by n-dot's distance from both ends of the heater 12 is set lower than the temperature at heating of parts of m dots (m is a positive integer) of the remaining heater part. Since the width scanning pitch corresponds to (m+n)-dots content shorter by the n dots of the heater than the dot arrangement length (b), each n-dot length are printed duplicatedly twice at printing. Thus, even when the width scanning pitch is in variation or the relative position between the paper 6 and the thermal head 1 in the width scanning direction is changed due to vibration of a carriage 2 attended with the main scanning, the print is never missing between lines.

IPC: B25J9/16
Filed: 1984-03-14
Abstract: PURPOSE:To reduce the interpolation processing time by revolving adversely the 2nd rotary axis by an amount equivalent to an angle at which the 1st rotary shaft should be revolved at a broken point in an interpolation mode of a desired route. CONSTITUTION:A processor 1 has interface with a memory 3, a table 4, etc. via a bus 2, and input/output ports 6 and 7 form an input/output part between a robot 9 and the bus 2. Then the robot 9 is driven up to a prescribed position with an indication given from a teaching box 8. The value of a displacement detector of an actuator is read and the corresponding position is stored to the memory 3. In an operation mode the data is read out of the memory 3 to perform the interpolation processing between data points. In this case, the revolving speed of the 1st rotary axis of a robot hand is reduced monotonously. At the same time, the 2nd rotary axis is revolved adversely by an amount equivalent to an angle at which the 1st rotary axis should be revolved at a broken point. In this case, the revolving speed of the 2nd rotary axis is increased monotonously to obtain an interpolation route.

Title: Safety device for elevator
Inventor: MIYAZAKI MASAYUKI
IPC: B66B11/02
Filed: 1992-03-04
Abstract: PURPOSE:To prevent the mischief by giving the image that the mischief during operation is dangerous and secure the safety of passengers by installing a switch which performs continuous output when a cage door is in perfectly closed state and detecting the completion of output from the switch in operation and putting off a lamp in a cage. CONSTITUTION:When a cage door is in perfect closed state, a switch contacts a projection, and a contact point 5b connected between the dc power source terminals P and N opens, and a relay 10 is deenergized. Since the cage door is automatically opened when a cage is landed on each floor, the contact point 5b closes, but since the contact point 13b of the relay opens, the relay 10 is kept in deenergized state. When a passenger plays a trick and the cage door is opened a little during the traveling of the cage, the switch slips off from the projection, and the contact point 5b closes. The contact point 13b is in closed state, since the cage is not landed, and the circuit of P-5b-13b-10-N is formed, and the relay 10 is deenergized. Accordingly, an all-time closed contact point 10b is opened, and the circuit of P-11-10b-12-N is opened, and a lighting circuit 12 is deenergized, and the lighting in the cage is put off.
