    摘要： The present invention's method and apparatus to generate test sequences for communication protocols input the data of the finite state machines (FSM) representing the specification of the communication protocols, and convert the test sequence generation problem to the SAT problem, and generate test sequences for communication protocols by solving the SAT problem. In addition, the present invention converts the test sequence generation problem to the SAT problem by modifying the FSM and describing the test sequence generation problem by using a conjunctive normal form formula based on the modified FSM. According to the present invention, by considering the multiple UIO sequences and the overlapping of the UIO sequences, the minimum length test sequence to check whether the states described in the specification of the protocol exist in the implementation of the FSM can be generated. According to the present invention, by considering the overlapping of the subsequences, the minimum length test sequences to check whether the state transitions described in the specification of the protocol is correctly implemented in the implementation of the FSM can be generated.

    摘要： A clamp jig has a positioning pin provided at the tip of a cylindrical member, and a clamp arm is mounted in a slit formed in this positioning pin, so as to be able to swing and so as to be able to axially advance and retreat. A reciprocating shaft is connected to the clamp arm by a connecting pin, and a spring force is applied to this reciprocating shaft in a retreating direction by a compression coil spring. A plunger 35 brought into contact with the reciprocating shaft is mounted in a drive housing so as to be able to axially reciprocate, and a female screw member driven by a motor is thread-connected to a male screw member secured to this plunger. Accordingly, it is made possible to reliably perform positioning and clamping, of a member to be fixed, and unclamping thereof by a low-cost motor.

    摘要： A fluid pressure cylinder has a piston rod 18 fixed to a piston 26 and projecting outside a cylinder body 23. A lock surface 43 inclining to a radial direction of the piston rod 18 is formed in an engagement member 31 provided in the piston rod 18. A lock rod 35 reciprocating in an about right-angle direction to the piston rod 18 is built into a lock cylinder 33 provided in the cylinder body 23. The lock rod 35 is provided with: a large-diameter section 35a fitted into a guide hole 36 formed in the lock cylinder 33; and a slide contact section 37 provided in the large-diameter section 35a via a constriction section 35b. The slide contact section 37 contacts with a radial-inner portion of the lock surface 43 when the lock rod 35 comes nearest to the piston rod 18.
