Abstract: A computer program production system, a computer program, and a production terminal instrument each cause a computer to execute service block selection processing of selecting a service block program from among selection candidate service block programs, trigger block selection processing of selecting a trigger block program from among selection candidate trigger block programs, action block selection processing of selecting an action block program from among selection candidate action block programs, and production processing of producing an application program by combining the selected block programs.
Abstract: Disclosed is a friction welding method including: a heating step wherein, in relation to joining surfaces (S1, S2) defined by opposite end surfaces of a pair of materials (W1, W2), the pair of materials (W1, W2) are moved from a state in which their axes are unaligned with each other, in a direction for aligning the respective axes with each other, to a prescribed position where the joining surfaces (S1, S2) are brought into contact with each other and friction heated; and a pressure contacting step wherein the pair of materials are brought into pressure contact with each other. The method is characterized in that the heating step and the pressure contacting step are carried out while rotating each of the materials (W1, W2) at the same rotation speed in the same direction, as seen from one side in the axial direction.
Abstract: A pressure detection device includes: a piezoelectric element that detects a pressure change via a diaphragm head or the like; a circuit board that is provided with a processing circuit that performs electrical processing with respect to a charge signal outputted from the piezoelectric element; a conductive housing member, which has conductivity and is disposed to cover (house) the circuit board, and which is connected to the ground of the circuit board; and a housing (a leading end side housing, the diaphragm head and a rear end side housing), which houses the piezoelectric element, the circuit board and the housing member, and which is electrically insulated from the piezoelectric element, the circuit board and the housing member.
Abstract: A machine tool (1) includes a spindle (32) supported on a support surface (37a) of a support body (37) with such an orientation that the longitudinal axis of the spindle extends along the support surface (37a). The spindle (32) is movable in a vertical direction that is perpendicular to the longitudinal axis of the spindle (32). The support body (37) is provided with a ventilation hole (80) extending through the support body (37) between the support surface (37a) and a surface (37b) facing in the direction opposite to the support surface (37a), to open toward the spindle (32).
Abstract: An automatic lathe includes a positioning block that positions a rod material, the rod material projecting from a main spindle contacting the positioning block, and a sensor that moves in a direction intersecting with a shaft center C direction of the main spindle to detect a cut off condition of the rod material. The positioning block includes a groove that allows movement of the sensor, and moves in the same direction as a movement direction of the sensor between a position that contacts the rod material and a position that has no contact with the rod material. The sensor moves along the path in the position that has no contact with the rod material.
Abstract: An electronic switch includes a rubber sheet that includes a first surface, a second surface opposite to the first surface, and a convex portion on the first surface. The convex portion of the rubber sheet includes a semispherical shape.
Abstract: A variation reduction mechanism of a stop position of a pointer includes a return gear that is driven in conjunction with a time display mechanism, a slip torque spring (friction member) that contacts the return gear to apply a friction force to the return gear to be driven, and a return spring (return spring member) that applies, to the slip torque spring, a torque of the return gear in a direction (dashed line arrow—R direction) opposite to a normal hand movement direction (arrow R direction).
Abstract: A push switch which can have a small separation distance from a side surface of a mounting board, when it is mounted on the mounting board through a step, is disclosed. The push switch includes a substrate having a first surface on which a first fixed contact point and a second fixed contact point surrounding the first fixed contact point are formed, a second surface located opposite to the first surface, a third surface extending from the second surface to a corner in a direction perpendicular to the first surface, and a fourth surface extending from the corner parallel to the first surface, and a conductive movable contact point having a peripheral edge is in contact with the second fixed contact point, and a center contacted by the first fixed contact point when the movable contact point is pressed, and the corner includes a groove recessed with respect to at least one of the third surface and the fourth surface.
