摘要： PURPOSE: To improve the performance of access to a distributed shared memory. CONSTITUTION: A main memory 106 is provided with a shared data consistency guarantee control specification instruction string memory 201, a work memory 202, a shared data memory 203, a shared data consistency guarantee control instruction string memory 204, a shared data management table 205, and a priority queue 206 with a shared data wait counter. A processor 104 executes an instruction string in the shared data consistency guarantee control specification inspection string memory 201 or receives network packets of other computers through a network interface 107 to execute the instruction string in the shared data consistency guarantee control instruction sequence memory 204. The instruction string in the shared data consistency guarantee control instruction string memory 204 refers to or alters the shared data management table 205 and the priority queue 206 with the shared data wait counter to control the consistency of the shared data stored in the shared data memory 203 and the synchronization of programs which operate in parallel.

摘要： PURPOSE:To increase strength per one place of a supporter, by integrating a lead wire and a retaining metal into an integrated structure. CONSTITUTION:The lead wires 1a, 1b of the rotor of a rotary electric machine are pushed against a pedestal 4 by a pushing metal 5; however, both of the lead wires 1a, 1b have a tendency to be deviated to the direction of an outer diameter by the centrifugal force of the lead wires 1a, 1b. In order to prevent the deviation, retaining metals 2a are projected from the lead wires 1a, 1b so as to abut against the pedestal 4 of the lead wires through an insulating piece 3. In this case, the retaining metal 2a, integrated with the lead wire 1a, is abutted against the pedestal 4 of the lead wire through the insulating piece 3. The retaining metal 2a, integrated with the lead wire 1b, is connected by silver solder or the like. According to this method, the strength per one place of a supporter, or strength against the centrifugal force, may be increased.

摘要： PROBLEM TO BE SOLVED: To ensure a noise margin even when a power supply voltage of an input output circuit connecting to both ends of a transmission line is fluctuated. SOLUTION: The transmission system 1 is provided with a transmission line 10, LSIs 30a, 30b connecting respectivelyt o both ends of the transmission line 10, and a reference level generating voltage divider 130 that is connected to the LSIs 30a, 30b. The reference level generating voltage divider 130 generates a reference level based on both power supply voltages of the LSIs 30a, 30b. The LSI 30a has a reference voltage adjustment circuit 110a that adjusts a reference voltage of a reference output 38a of an input circuit 80a based on the reference voltage (that is similar to the case with the LSI 30b). Thus, even when a power supply voltage between the LSIs is fluctuated, a maximum input difference voltage is ensured. Thus, malfunction hardly takes place even when the amplitude of the transmission signal is decreased and low power consumption and high rate signal transmission are attained.

摘要： PURPOSE:To alleviate a thermal stress applied on a coil insulator which is generated during the cooling and heating cycle of the windings of a rotor and a stator. CONSTITUTION:A winding 3 is inserted into a slot 2 of a core 1 of a rotary electric machine and a wedge 21 is also inserted thereto. A pair of heat insulating members 4a, 4b are counterposed at an area (for example, at the area between the wedge and winding), where a high surface pressure is applied, on a winding insulator 3b in the slot 2 and one heat insulating member 4a among these members is bonded with a winding insulator 3a so that it moves in the axial direction depending on thermal expansion of winding and contraction thereby by temperature drop. Meanwhile, the other heat insulating member 4b is fixed to a core and slidable members 5a, 5b having small friction coefficients are provided between the movable heat insulating member 4a and the fixed heat insulating member 4b.

摘要： PURPOSE:To prevent the application of stress to a root section in a connecting terminal by forming an interpole connecting section for a field coil in constitution in which the connecting terminal can be moved on thermal expansion. CONSTITUTION:A field coil 3 is shaped by winding flat type copper wires to a multilayer shape in an edgewise winding manner, and inter-wire insulators 4 are executed among each winding. Connecting terminals 5 for connections to the next poles are each fitted to an uppermost-layer winding section and a lowermost layer winding section. In interpole connection, the connecting terminals 5 for adjacent coils are connected alternately, and mounted to a support fitting 6 by using recessed type support fittings 11. The size of a groove for the recessed type support fitting 11 is represented by connecting terminal width added with a thermal expansion value after insulation. Accordingly, the application of forced stress to root sections (a) in the connecting terminals 5 is prevented.
