Title: Bag opening device
Inventor: OKABE KIMIAKI
IPC: B65H47/00
Filed: 1995-05-23
Abstract: PURPOSE: To perform an opening work of a bag body in a simple and sure manner by a method wherein pairs of holding bodies in which holding bodies of each pair of bodies are alternately disposed in the vertical direction to hold a bag body and a periphery of the bag body on the side of the opening thereof is displaced in the direction of the surface of the periphery to forcibly separate the bag body. CONSTITUTION: For opening a packaging bag F, a film raw fabric (f) is taken out to an opening point just below a separation point and left holding chucks 44 and right holding chucks 44 each are pressed against both front side edges and both rear side edges of the fabric, respectively. And the held portions of the fabric (f) are bent in a zigzagged manner along the opposed surfaces of adjoining holding claws 44a, 44b constituting each of the chucks 44. Hereupon, since a nonskid rubber is bonded onto each of the surfaces of the claws 44a, 44b, a frictional resistance is generated between pressed surface of the fabric (f) and surface of the the rubber. As a result, if the front and rear surfaces of the fabric (f) are displaced in the surface direction, the fabric is forcibly separated.  And thereafter, a part of the thermally bonded fabric (f) between the closed part and the held part is cut in the width direction by means of a cutter 41 to separate and form one packaging bag F.

Title: Reversion preventing device for inertia body
Inventor: TAKEUCHI YOSHINORI
IPC: E02F9/22
Filed: 1996-05-22
Abstract: PROBLEM TO BE SOLVED: To prevent repetition of reverse running of a hydraulic motor after inertia rotation of a hydraulic motor is stopped. SOLUTION: A control cylinder 37 is arranged in a state to be positioned between a valve casing 22 and a spring chamber 31 and a pilot pressure is introduced in the oil chamber 37D of a control cylinder 37. By changing the set length of a set spring 33 by causing slide displacement of a control piston 39 from an initial position to a movement position, the set pressure of the set spring 33 is changed. This constitution causes slide displacement of a spool 28 by a piston 35 against the set spring 33 even when, during inertia rotation of the hydraulic motor, a pilot pressure exerted on the piston 35 from a shuttle valve 40 is low, a reversion preventing valve 21 is reliably operated to intercommunicate first and second main lines.  A difference between the main lines is escaped from the high pressure side to the lower pressure side, and reversion operation of the hydraulic motor is reliably prevented.

Title: Data processor
Inventor: ONO SHOSHIRO
IPC: G06F9/38
Filed: 1987-06-17
Abstract: PURPOSE:To prevent the breakdown of a data processor and to improve its reliability by prefetching again an instruction out of an erroneous instruction via an instruction prefetching circuit in case the occurrence of an error is not detected by a detecting means and not stored in a storing means yet. CONSTITUTION:An arithmetic process holding circuit 4 detects the occurrence of a correctable error of an arithmetic processing circuit 2 and the detection of said error occurrence is not stored in an error indicator. In such a case, an instruction prefetching circuit 1 prefetches again an instruction out of the instruction given when the circuit 2 has a correctable error in a transfer mode. Thus the circuit 2 can receive an instruction when it has a correctable error. Thus, it is possible to prevent the breakdown of a data processor and to improve the reliability of this processor.
