A PID parameter adjustment device includes a model storage unit (1) which stores a mathematical model of a controlled system, a PID controller storage unit (2) which stores a controller algorithm, a constraint condition storage unit (3) which stores constraint conditions on operation, a simulation computation unit (5) which executes a simulation to simulate a control system on the basis of the constraint conditions, an ideal control result storage unit (6) which stores an ideal control response characteristic, an evaluation function computation unit (7) which computes an evaluation function value representing the proximity between a simulation result and the ideal control response characteristic, and a PID parameter search computation unit (8) which searches for PID parameters which makes an evaluation function value optimal by executing a simulation while changing the PID parameters.

A method and apparatus for transmitting document data enabling transfer of document data over a communication path assigned the highest possible priority among a plurality of communication paths. First, an attempt is made to transfer document data over the highest-priority communication path. If the attempt has failed, the document data are transferred over a communication path which is lower in priority than the highest-priority communication path. After information for one page of text data has been transferred over the lower-priority communication path, an attempt is again made to transfer the remaining part of text data over the highest-priority communication path.
摘要:
An exhaust manifold M is comprised of a plurality of inner exhaust pipe shells secured to an upper flange, and a plurality of outer exhaust pipe shells secured to the upper flange to individually cover the inner exhaust pipe shells, wherein a downstream end of each of the corresponding inner exhaust pipe shells slidably contacts an annular bead bulging from an outer peripheral surface of the downstream end of the outer exhaust pipe shells. An inner collecting pipe shell communicates with the plurality of inner exhaust pipe shells and is secured at its upstream end to the plurality of outer exhaust pipe shells, and an outer collecting pipe shell which is secured at its upstream end to the plurality of outer exhaust pipe shells covers the inner collecting pipe shell. A downstream end of the inner collecting pipe shell slidably contacts an annular mesh member interposed therebetween. Sliding portions for absorbing a difference in the axial thermal elongation between inner and outer double walls are provided separately at the downstream end of an exhaust single pipe and the downstream end of an exhaust collecting pipe. Thus, the sliding stroke in each of the sliding portions can be set to a small value, and the absorption of the thermal elongation can be carried out smoothly.

An ink jet recording sheet is disclosed which has excellent ink retention properties, color development properties, weather resistance and water resistance, and which is substantially free from curling even if it has its only one side provided with an ink receiving layer. In particular, the present invention relates to an ink jet recording sheet which is extremely suited for use in poster applications. The ink jet recording sheet comprises: a substrate having its at least one side provided with an ink receiving layer; the ink receiving layer containing a nonionic surfactant and a binder resin, solid content of the nonionic surfactant being in a range of 11% to 20% by weight of total solid content of the ink receiving layer, the binder resin containing a silanol group-modified polyvinyl alcohol as a component thereof in an amount of 70% by weight or more of solid content of the binder resin.

An artificial bait which can provide a great effect to attract fish by means of light emission or reflection from air bubbles contained in the artificial bait. A large number of air bubbles are enclosed within a artificial bait main body formed of elastic material having flexibility and light transmissible property wherein the air bubbles may be deformed to enhance the attractiveness of the bait.

The invention relates to a lure performing a new action which attracts a fish to make a good catch of fishing. The lure includes: a rotary member 16 rotated by the action of resistance to a water current; and a extrusion member 18 moved with the rotary member 16, resisting the water current so as to extrude water forward.
摘要:
A videophone at e.g., a called location, receives sound signals, video signals and control signals through a communication circuit from a communication line and originating at, e.g., a calling videophone. A start signal detecting means, within the called videophone detects a storage start requesting signal from received control signals originating at a calling videophone. At the time of such detection, a coding circuit within the called videophone again encodes the video signals, that are received by the communication circuit and continuously decoded by a decoding circuit, and transmitted by the calling videophone but only by one frame therefrom and stores the frame into a storage circuit. After storing the one frame, a change-over circuit in the called videophone switches to the storage circuit to continuously store the subsequent incoming coded video and sound signals for eventual playback.

A driving rotary shaft is rotatably carried on a compressor body of a variable displacement compressor. On axial one side of a sleeve slidably carried on the driving rotary shaft, there is disposed a first spring of a displacement setting device for biasing the sleeve in one axial direction and holding a stopper, with which the sleeve is engageable, at a stop position on the driving rotary shaft. On the axial other side of the sleeve, there is disposed a second spring of the displacement setting device for biasing the sleeve in the other axial direction, the second spring being weaker than the first spring. At the starting of the compressor, the first spring holds the stopper at the stop position against a repulsive force of the second spring to hold the sleeve engaged with the stopper at a fixed position. This makes it possible to set the strengths of individual members and the capacity of a clutch to be smaller than those in the prior art, leading to reductions in size, weight and cost of the entire compressor.
