Title: Circuit breaker
Inventor: TAKAHASHI MITSUGI
IPC: H01H33/20
Filed: 1987-06-16
Abstract: PURPOSE:To make such a circuit breaker that is excellent in high voltage breaking capacity securable by having an arcing horn and an intermediate electrode opposed to each other so as to cause at least a part of both at time of opening the electrode to become almost paralleled. CONSTITUTION:With the dissociation between a fixed contact 3 and a travelling contact 4, there is produced an arc between both these contacts 3 and 4. Since high-pressure metallic vapor is spouted in the almost vertical direction from a leg of the arc shifted to the opposed surface 10 of an arcing horn 9, conductivity between both opposed surfaces 10 and 12 comes high, whereby the arc quickly shifts to an arc between the opposed surface 10 of the arcing horn 9 and the opposed surface 11 of an intermediate electrode 11 to be parallelly opposed and an arc between a topmost grid 13 and an arc runner 14. And, since each conductive route of the arcing horn 9 and the intermediate electrode 11 is almost parallel with each other and each direction of a current is reverse, the arc is magnetically driven so effectively in each tip direction of the arcing horn 9 and the intermediate electrode 11, thus it generates high arc voltage. With this constitution, such a circuit breaker that has excellent high voltage breaking capacity is securable.

Title: Gpib communication system
Inventor: AKASE YOJI
IPC: G06F13/366
Filed: 1988-06-17
Abstract: PURPOSE:To hold an autonomous service request from a slave device and to attain data transfer by means of the control of a master device by permitting the master device to periodically execute serial polling and reading status bytes. CONSTITUTION:The master device 2 and the slave devices 3 and 4 are connected through a GPIB bus interface 1, and the master device 2 has a serial polling period part 5 which periodically executes serial polling. Either one of the slave devices 3 or 4 makes an SRQ signal active through a GPIB bus interface 1 and informs the master device 2 of the service request. Since an SRQ detection part is removed from the master device 2, it does not recognize the service request. The master device 2 periodically reads the status bytes of the slave devices 3 and 4 by the serial poll period part 5, and detects the service request. Thus, the master device periodically executes serial polling and reads the status bytes by the main lead of the master device 2, and therefore the autonomous service request from the slave devices are held so as to transfer data by the control of the master device.

Abstract: PROBLEM TO BE SOLVED: To detect presence of a detect projecting in a passage accurately by setting the size of an internally moving spherical body smaller than the diameter of an opening and the nominal diameter of the passage but larger than the outlet diameter. SOLUTION: The diameter of a spherical body 10 is set smaller than the diameter A of an opening 3a at a tank section 3 and the nominal diameter C of the passage at a port 4 but larger than the outlet diameter B and tour spherical bodies 10 are located at respective port inlets. Attitude of an intake manifold 1 is then varied by driving a turning unit 14 so that the spherical body 10 is removed from the recess in a spherical body holding plate 11a and passed through the opening 3a and the port 4. If a projecting defect is not present in each port 4, the spherical body 10 stagnates in the vicinity of the outlet of the port 4 and detected by an insertion sensor. When four spherical bodies 10 are detected, a decision is made that a projecting defect is not present in each port 4.  When three spherical bodies 10 or less are detected, a decision is made that a projecting defect is present in the port 4 of a sensor which does not detect the detect. After determining the presence of a projecting defect, the turning unit 14 is turned reversely and the spherical body 10 is returned back to the recess in the spherical body holding plate 11a.
