Title: Ignition time correcting device for internal combustion engine
Inventor: KOMURASAKI SATORU
IPC: F02P5/145
Filed: 1980-04-03
Abstract: PURPOSE:To correct the deviation of the ignition time by detecting the deviation of the ignition time upon the predetermined operation of the engine and correcting the ignition time so as to set it at the normal ignition time in correspondence to the detection memory output. CONSTITUTION:A reference signal generated from a reference signal generator 2 is supplied to a phase difference angle detection circuit 4, and an ignition signal generated from an ignition signal detector 1 is supplied to a phase difference angle detection circuit 4 through a phase shifting circuit 3. Further, the phase difference angle detection circuit 4 produces a correction signal of a pulse length corresponding to the phase difference angle between both signals. When the engine is operated in an idling mode in which an output signal from an idling detection circuit 5, a correction signal is supplied to a reversible driving device 7 through a gate circuit 6. By adjusting a variable resistor 8, the phase shifting quantity of the phase shifting circuit 3 is adjusted, and the ignition signal is maintained in a predetermined phase relationship with respect to the reference signal. Further, an abnormality detection circuit 12 affords an output signal from a set signal generating circuit 10 to the phase shifting circuit 3 when any abnormality is detected in the correction signal, thereby preventing a lead angle of large width at the ignition time.

Filed: 1998-02-10
Abstract: PROBLEM TO BE SOLVED: To manufacture a dynamic bearing device in a simple process without using a coining process, and to improve the durability by forming a surface part including a dynamic pressure surface of a thrust plate of a resin material. SOLUTION: In thrust dynamic pressure bearing parts SBa, SBb which are arranged adjacent to each other, each dynamic pressure surface on the side of a bearing sleeve 22 or a counter plate 25 and each dynamic pressure surface on the side of a thrust ring 16 are arranged opposite to each other in the axial direction through a narrow gap. The thrust ring 16 is formed of a prescribed resin, its dynamic pressure surface is formed of a resin surface, and a groove for generating the dynamic reassure is recessed in the dynamic pressure surface. When a hub 21 is rotated, the lubricating fulid is pressurized by the pumping action of the grove for generating the dynamic pressure, the dynamic pressure is geneted thereby, and the hub 21 is shaft-supported in the thrust direction.  Because the thrust ring 16 is formed of the resin material with high accuracy in a simple process, the metallic corrosion generated when a metallic material is used can be prevented, and the durability is improved.

Title: Assignment problem solving device
Inventor: KOYANAGI SHIGERU
IPC: G06F19/00
Filed: 1990-02-27
Abstract: PURPOSE:To obtain an optimum solution of the assignment trouble by using a network where neural elements whose number is equal to the number of modules are mutually coupled and setting a coupling coefficient between neural elements to start the network and changing the coupling coefficient value to start it at each time of detecting the convergence of output. CONSTITUTION:Neural elements 1 whose number corresponds to the number of n- number of modules are mutually coupled with coupling coefficient parts 2 among them, and the output value is multiplied by a weight Wij, and the weighted sum of the output value of each neural element and the weight Wij is calculated. The weighted sum and an external input Ix from a terminal 3 are subjected to threshold operation to determine the output value. This operation is repeated until outputs of elements 1a to 1n are stabilized to '1' or '-1' and the module corresponding to each element is divided into two. When a convergence discriminating part 4 detects that all neural elements are converged to the balanced state (divided into two), two-divided results of the output are stored in a memory, and the neural network is started again and a weight calculating part 6 is used to set a new coupling coefficient to coupling coefficient parts 2 in accordance with convergence results of the memory 5. By this constitution, the simple neural network is used to perform effective assignment to cells of plural modules.
