Abstract: PURPOSE: To detect the joint of a photodetector belt and to prevent a latent image from being formed across the joint. CONSTITUTION: A sensor 40 is placed while facing one side of a light transmissive photodetector belt 17, and an LED print bar 12A is placed while facing the other side of the belt (the sensor 40 and the bar 12A face each other). When a joint 22 of the belt 17 passes between the bar 12A and the sensor 40, the joint 22 is detected by the sensor 40 and sent to a joint detection (identification) circuit 50 and a characteristic output containing information on the width and concentration of the joint is generated. The joint detecting output from the circuit 50 is sent to a controller circuit 15 and used for controlling the operation of an imager, and the latent image is surely prevented from being formed across the joint.

Title: Monitoring method for coupling of reel loading mechanism in magnetic tape device
Inventor: SAIJO HIROAKI
IPC: G11B15/26
Filed: 1990-02-21
Abstract: PURPOSE:To improve the reliability of cartridge loading operation by counting a pulse outputted according to the angle and the direction of the rotation of a reel within prescribed time, and outputting a signal to decide a coupling state according to the integrated value of the pulse. CONSTITUTION:After a cartridge 1 is loaded to a reel motor 8, the reel is stopped, and it is rotated in a tape draw-out direction by increasing gradually the generated torque of the motor 8 under the control of a motor drive control circuit 12. At that time, an output pulse from a tachometer 9 is counted by a tachometer pulse counter 13 of a rotation pulse integration circuit 10 during the prescribed time set by a timer 16. Then, the integrated value of the counter 13 and a reference value sent from the control circuit 12 are compared with each other by a comparator 14, and a compared result is inputted to a coupling state decision table 15, and the signal to instruct a countermeasure in the future is outputted. As the countermeasure, the retrial of the loading operation is executed, for instance, in the case of no rotation, reverse rotation and very small rotation. Thus, the reliability of the cartridge loading operation can be improved.

Title: Cock valve
Inventor: KAWAMURA KIMINARI
IPC: F16K27/04
Filed: 1996-02-28
Abstract: PROBLEM TO BE SOLVED: To prevent a sealing member from sustaining damage when a valve is opened or closed, by gradually increasing a radius a radius of the port side of a valve casing from near a joint such that it becomes larger than a value of the sum of a radius of the sealing member and the length of a projection. SOLUTION: A cock valve has hollow space 8 whose radius of the port side of a valve casing is gradually increased from a value of the sum of a radius of a sealing member 7 and the length of a projection 9. According to this structure, even if the projection 9 is formed at the valve casing side 1 when a hole is drilled into the inner surface of the port 3 from the axial direction of the port 3, when a valve element 4 is moved and a sealing member 7 passes the port 3, the tip of the projection 9 is in the hollow space and is not put into contact with the sealing member 7 and the sealing member 7 is not damaged. Since the hollow space 8 has a radius increased gradually, it does not form an edge and thus does not damage the sealing member 7 when it passes.

Abstract: PURPOSE:To attain sure transmittal confirmation by sending data simultaneously from a master station to plural terminal equipments and sending a defective data to the master station after the reception of the data from the master station when a terminal equipment detects an error. CONSTITUTION:A master station M uses an information transmission reception control circuit 1 to generate a data for the purpose of sending a simultaneous signal to terminal equipments A1, A2, AN and sends a signal to a transmission line via a transmission reception interface circuit 4 from a simultaneous signal transmission circuit 2. The terminal equipments A1, A2, AN receive the signal at a simultaneous signal reception circuit 6 via a transmission reception interface circuit 5. When the data is normal, an information transmission reception control circuit 8 executes the normal data processing. When the data is in error, a defect reception data signal transmission circuit 7 sets its own station address to an address designation section to generate a frame and the result is sent to the master station M via the transmission reception interface circuit 5.

Filed: 1990-02-23
Abstract: PURPOSE:To get rid of danger due to the reverse flow of combustion gas high in temperature by providing a valve control device which opens a nitrogen inflow valve provided at the front step of an anode when the detected differential pressure between the pressure of the anode in a fuel cell and the pressure of a reformer's burner is found to have been less than a set one. CONSTITUTION:A differential pressure detecting means 5 detecting differential pressure between an anode 1b and a reformer's burner 2a is provided for the combustion gas exhaust line of the anode 16 of a fuel cell main body 11, and the detecting means 5 is connected to the control device 20 of a nitrogen injection valve 15 which supplies nitrogen gas 22 to the anode 1b. When a fuel cell generating system is in a maintenance operating condition, differential pressure signals between the anode 16 and the reformer's burner 2a are forwarded to the control device by the differential pressure detecting means 5. When the differential pressure signal is found to have been less than a set signal set in the control device, since it is judged that this will get into danger of reverse flow from the reformer's burner 2a, a nitrogen inflow valve 15 connected to the control device 20 is thereby opened so that nitrogen gas 22 is supplied to the anode 16. By this constitution, danger due to the reverse flow of combustion gas which is caused by an increase in pressure within the anode 1b, is thereby got rid of.

IPC: G10L15/06
Filed: 1982-03-17
Abstract: PURPOSE:To shorten the access time, by using a dynamic RAM to a dictionary memory for pattern matching, dividing a standard pattern into parts of each fixed length to store them in plural banks and reading out these banks in parallel to each other. CONSTITUTION:A dictionary memory 2 for pattern matching which is used to a character reader or a voice recognizer, etc. is divided into plural banks. The standard pattern data which is loaded to a data register 1 from an external memory is divided into parts of each fixed length and stored in the above-mentioned banks. Then the matching is obtained between an input pattern stored in an input memory 5 and the standard pattern stored in the memory 2 through a matching circuit 7. In this case, it is just required for four banks of the memory 2 to designate the addresses equivalent to 64 bytes while the address is designated to the data equivalent to 256 bytes of the input pattern. As a result, the access time of the memory 2 can be effectively reduced down to 1/4.
