Abstract: A device for changing the speeds of the front and rear wheels in a four-wheel-drive vehicle including a continuously variable speed-changing mechanism for the front wheels, which changes the input rotational speed and outputs it to the front wheel drive shafts, and a continuously variable speed-changing mechanism for the rear wheels, which changes the input rotational speed and outputs it to the rear wheel drive shafts. The device for changing the speeds of the front wheels and the rear wheels comprises a detector means for detecting the operation conditions of the vehicle, a steering angle sensor for detecting the steering angle of the vehicle, and a controller for variably controlling the speeds of the continuously variable speed-changing mechanisms based on the operation conditions of the vehicle.

Abstract: A program conversion device includes a formal initialization expression generating unit, an actual initialization expression generating unit, and an object generation statement translating unit. The formal initialization expression generating unit focuses on a definition of an object generation function written in a source program and generates, if the object generation function does not perform any processing other than setting values in member variables of an object, a formal initialization expression which is the member variables represented by formal parameters. The actual initialization expression generating unit focuses on an object generation statement and generates, if a formal initialization expression that corresponds to an object generation function to be invoked by the object generation statement has been generated, an actual initialization expression.

Abstract: In an optimization apparatus embedded in a compiler apparatus that compiles a high-level language program to a machine language program, equivalence relations among a plurality of expressions are analyzed in a short time period by calculating an equivalent expression set group of each basic block, the equivalent expression set group being composed of equivalent expression sets with equivalence relations. Specifically, an equivalent expression set group at the entry point of a basic block is calculated from equivalent expression set groups at the exit points of basic blocks that precede the basic block, and then an equivalent expression set group at the exit point of the basic block is calculated from the equivalent expression set group at the entry point of the basic block. These calculations are repeated until there are no more changes to the equivalent expression set group at the exit point of any of the basic blocks.

Abstract: A debugging support apparatus for a processor that executes a plurality of instructions in parallel displays lines of source code statements in a user program that are executed in parallel. Code execution unit 15 executes the program. When execution of the program is interrupted at a breakpoint set in advance at a line of a source code statement, user interface unit 11 searches parallel execution information storage unit 5 for lines to be executed in parallel with the line set the breakpoint, and displays a source code statement of the line set the breakpoint and source code statements of the lines to be executed in parallel. As a result, a user is able to visually recognize which lines of source code statements are executed in parallel.

Abstract: Internal variables generated by a compiler are assigned to machine resources such as registers and memory by the resource assigning unit 11, and when the assembler code generation unit 18 has outputted an instruction sequence, the alias accessibility analyzing unit 19 registers memory access instructions in the instruction sequence in the assigned resource information 14 according to whether the instructions have a possibility of access by alias. The assembler code optimization unit 20 refers to the assigned resource information 14 and performs optimization at assembler level, thereby reducing the program size and execution time of the instruction sequence.

Abstract: The object of the present invention is to prevent disconnection of leading wirings extending across a seal area in a liquid crystal display panel based on a pixel-on-top structure. Scanning lines, signal lines and TFTs are formed over an insulating substrate. Pixel electrodes are formed over these components with an inorganic insulating film and an organic insulating film interposed therebetween. Around the display area in which the pixel electrodes are arranged are placed driver circuits that apply voltage signals to the scanning lines and the signal lines. A sealant is placed in boundary area (seal area) between the display area and the driver circuit area. At the same time the pixel electrodes are formed, ITO film is formed on the inorganic insulating film to overlies leading wirings that extend across the seal area.

Abstract: The basic block division unit 2 divides the instruction sequence into basic blocks which are sequences with a continuous execution order. The control flow analysis unit 3 analyzes the control flow between basic blocks. The global equivalence relation analysis unit 4 traces the control flow between basic blocks and analyzes equivalence relations between resources, such as memory and registers, which cross over between basic blocks. The code is then optimized using these equivalence relations which cross over between basic blocks. In this way, the equivalence relations between resources in the program are analyzed globally and are used in the optimization of the code, so that a greatest possible reduction can be achieved in the code size and execution time of the program.

Abstract: A damper device for rotary motion is disclosed which is small in size, has an excellent durability and can optionally change damping characteristics from the outside. Rotation of an input shaft is transmitted to a cylinder tube through a rotation transmitting device of loading cam type, thereby rotating an output shaft engaged with the cylinder tube through splines. When the rotational speed and torque of power to be transmitted is fluctuated, the cylinder tube is displaced against the resiliency of a conical plate spring and the volume of a pressure chamber is reduced. A viscous liquid in the pressure chamber is then discharged to the outside through a throttle hole. A relative displacement between the input and output shafts absorbs vibrations in terms of energy corresponding to the product of the mass and changes in the angular speed of members which are displaced in synch with the input shaft.

Abstract: It is possible for the present invention to operate with the optimal control to prevent a ram from overshooting in a case that a load acting on the ram is decreasing rapidly, like a stamping machining process. Linking a hydraulic circuit which consists of a hydraulic pump 3 and a hydraulic cylinder 2 to make the ram 1 for the hydraulic press equipment move upward and downward and a full-bridge hydraulic circuit with four proportional sheet valves V1 through V4, the working timings of the proportional sheet valves V1 through V4 are controlled by a NC controller 9. In the normal operation, operating the proportional sheet valves V2 and V3 with the turn-on-off control system and with the meter out control system, oil pressure PU acting on the upper chamber 2U of the hydraulic cylinder 2, driving the ram 1 by the piston 10 moving downward, a work is stamped out. The NC controller 9 detects the running by inertia of the ram 1 in the instance of having stamped out a work in the stamping out machining process.

Abstract: In an active matrix type liquid-crystal display device, in a peripheral circuit portion, there is arranged a TFT having a high mobility and capable of allowing a large amount of on-state current to flow. In a pixel portion, there is arranged a TFT having a small off-state current. These TFTs having different characteristics are constituted by using crystalline silicon film whose crystal has grown in a direction parallel with a substrate. That is, an angle formed between a crystal growing direction and a carrier moving direction are made different from each other, thereby to control a resistance imposed on the carriers when moving to determine the characteristics of the TFT. For example, when the crystal growing direction coincides with the carrier moving direction, high mobility can be given to the carriers. Further, when the crystal growing direction is arranged perpendicular to the carrier moving direction, the off-state current can be lowered.

Abstract: The toroidal continuous variable transmission for four-wheel drive automobiles distributes a greater torque to the rear wheels than to the front wheels. The torque of the first driven gear is distributed 50% each to the first output shaft and the second output shaft. The torque of the second driven gear is transmitted 100% to the second output shaft. Hence, when the front wheels are connected to the first output shaft and the rear wheels to the second output shaft, the ratio between torques distributed to the front and rear wheels is about 1:3. In the event that only the front wheels should race reducing the transmitted torque, the torque transferred to the second side gear that is not racing also decreases. The rear wheels, however, are supplied with a torque from the second driven gear and therefore can secure at least 50% of the input shaft torque.
