Title: Weighing device
Inventor: MORITA RYOICHI
IPC: B65G65/40
Filed: 1988-01-11
Abstract: PURPOSE:To obtain the small-sized weighing device which has small power loss accompanying metering by allowing a group of bodies to be weighed which are loaded at feeding operation time and that at following feeding operation time to be present on a conveying means at a specific interval in the front-rear direction. CONSTITUTION:The metering device 4 has a lateral drawing conveyor 21, whose ends are both supported supported by load cells 28 and 28. Then a group 2A of bodies to be measured moves toward a discharge part 23 while increasing in amount and when its tip reaches a sensor 29, a controller (not shown in figure) receives a signal from the sensor 29 and outputs a closure signal for a cut gate 26 to an actuator 27, thereby closing the gate 26. Simultaneously with the end of this feeding operation, cells 28 measures the weight of the object bodies 2 and inputs the weight to the arithmetic means of the controller. The weight measurement by the cells 28 is completed until the tip of the group 2A of the bodies reaches a sensor 30. Therefore, the weight measurement is carried out in a state wherein only the group 2A of the bodies is present on the conveyor 21, so as error in the measurement is small and its accuracy is high.

Title: Converter
Inventor: JIYON JIYOOJIFU PIICHINITSUKU
IPC: H02M7/66
Filed: 1990-01-10
Abstract: PURPOSE: To provide a converter for a storage battery system when an average load is not more than the half of a peak load by making such an arrangement that the current of first energy is in a unidirection and the current of second energy is in a bidirection when the selective opening and closing operation of a switch group is performed. CONSTITUTION: The voltage of a load RL is directly proportional to a voltage VB2b in a closed state of both switches S1, S3. In the closed state of both switches S2, S4, the voltage of the load RL becomes VB1 ±VB2a . Both switches S1, S2 are controlled so as to operate when VB2 =VB1 , and at that moment, a current does not flow in a circuit formed of batteries B1, B2a, B2b, and when the batteries are changed over from discharging to charging, the switches S1, S2 are simultaneously closed. Both switches S3, S4 are changed over at a zero VRL (voltage at a load RL) to generate two-pole outputs. Therefore, when the average load is not more than the half of a peak load, a converter for a storage battery system can be obtained.

Title: Implement and method for detection of fitting of connector terminal
Inventor: SAWAYANAGI MASAHIRO
IPC: H01R43/20
Filed: 1996-01-16
Abstract: PROBLEM TO BE SOLVED: To confirm whether a connector is nondefective after a fitting inspection has been finished by a method wherein a display means by which a 'passed' mark indicating that it has passed the fitting inspection, in a state that the connector is fitted completely is put on the front edge of the connector is installed at a detection implement body. SOLUTION: When the mounting and attaching state of a terminal metal fitting at a connector 2a is good in such a way that detection pins 4 are inserted into a terminal housing chamber without any trouble, a fitting part 5 at the connector 2 is caught on a locking pit 6 at a detection implement 1a so as to be locked by the detection implement 1a. In a state that it is confirmed to be good in a fitting inspection by a lock sound generated at this time, a 'passed' mark displaying an inspected nondefective product by using a pen 9 (a display means) is put on the front edge of the connector 2a. Thereby, it is possible to easily confirm that the inspection of the connector 2a is passed as a nondefective product after the inspection has been finished.  In addition, when the connector 2a is inserted halfway into the inspection implement 1a so as not to be locked, a gap is generated between it and the front edge of the connector 2a, and the 'passed' mark by the pen 9 is not put on.

Abstract: PURPOSE: To discriminate occurrence of faults by using a radio wave signal as a transmission medium so as to send control information thereby sending state information of all terminal equipments and a transmission path to a communication processing unit corresponding to each terminal equipment. CONSTITUTION: Plural terminal equipments 101 are connected via a communication processing unit 110 corresponding to each terminal equipment and lots of data are communicated at a high speed between the terminal equipments via an optical communication means 111 using a light with high directivity as a medium and built in the terminal equipment 110. In this case, the processing unit 110 uses a low directivity radio wave as a medium to send status information of its own unit to all other terminal equipments 101 as control information. On the other hand, a radio wave reception means 112 receives the control information and a collection means 113 corresponding to all the terminal equipments 101 belonging to the network acquired the status information via the means 112.  Thus, when a detection means 114 detects a fault, a discrimination means 115 specifys a fault occurrence location based on the result of detection and the status information of all the terminal equipments 101 for the restoration processing by a restoration means 116.

Filed: 1982-01-18
Abstract: PURPOSE:To recognize characters in reference to a dictionary corresponding to a blurring process, by giving the weighted average to each feature element of an input character pattern with the contiguous elements and in response to the degree of complicacy of the input character pattern and then having the blurring process. CONSTITUTION:An optical input 1 given from a slip is fed to a photoelectric converting part 2, and a character estimated region is decomposed into (128X 128) picture elements. Then each picture element is converted into a binary digital signal. A coefficient deciding part 10 contains a table which shows the correspondence between the complicacy degree of an input character pattern and a blurring coefficient that is used to give a blurring process to the input character pattern. Thus the part 10 receives the complicacy degree of the input character pattern and decides the blurring coefficient based on the table of blurring coefficient. A blur processing part 11 receives a feature matrix of the input character pattern and the blurring coefficient and gives the weighted average to each feature element by means of two elements which are contiguous with each other in the direction orthogonal to the stroke direction. Thus the noticed feature element is blurred, and a blur feature matrix is produced.
