Title: No-contact ignitor of internal-combustion engine
Inventor: IWATA MASAO
IPC: F02P5/155
Filed: 1984-03-02
Abstract: PURPOSE:To enable a capacitor to be charged with energy discharged to an ignition coil to the maximum capacity of the capacitor and perform ignition control exactly by disposing an exciter coil and a trigger coil with specific relationship between their phases, with respect to a triple-pole rotor. CONSTITUTION:When a rotor 1 is turned, a no-load voltage is induced in an exciter coil 2 and a trigger coil 3. Then, a capacitor 5 is charged with a voltage induced by the coil 2 and thereafter, capacitors 12 and 14 are charged with a reversely induced voltage. At this time, a thyristor 18 is turned on by the voltages developed at both ends of a resistor 15 and thyristors 22 and 7 are maintained in the off state. After that, when the thyristor 18 is turned off and a Zener diode 19 is broken over, the thyristor 22 is triggered on and the capacitor 14 is discharged. Sequentially, the thyristor 7 is turned on and the capacitor 5 is discharged so that spark is generated at an ignition plug 9 via an ignition coil 6.

IPC: G11C29/00
Filed: 1985-03-01
Abstract: PURPOSE:To evaluate a semiconductor memory by counting the number of defective bits at every word line, and comparing the number of counts with preset allowable limit value. CONSTITUTION:Addresses of a line and column are shown by i, j, respectively and the address of a memory cell is shown by (i, j). Cells up to (M-1, N-1) address are written successively in a total memory cell, such as from cell (0, 0) to (0, N-1), from (1, 0) to (1, N-1). Data are read out from (0, 0) cell, and compared with expected value data by a comparator. When the coincidence of data is obtained, column address is increased, and advanced to (M-1, N-1) address, and when there is not discordance, it is judged as an acceptable product and the evaluation is completed. If the discordance occurs on the ray, the counter 11 is increased, and the content of the counter 11 is compared with a set value by a comparator 12 at every N-1 address of column address, and when the set value is exceeded, a Fail signal is generated and the evaluation is terminated. Thus, the number of defective bits can be checked at every word line.

Title: Method of processing speed data of internal combustion engine
Inventor: BENJIYAMIN JIEEMUSU BURATSUDOS
IPC: G01M15/11
Filed: 1992-01-31
Abstract: PURPOSE: To control an engine in correspondence with surface roughness by measuring and analyzing variations and distribution of the variations in the speed of the engine, and detecting surface roughness in accordance with the data. CONSTITUTION: A wheel 2 is driven via a transmission 3 in an engine 1. A detector 6 provides signals of surface roughness to outputs 9 and 10. The output 9 is connected to an antilock brake system 11 and the output 10 is connected to a traction system 12. For example, the antilock brake system 11 generates a wheel speed difference signal from the wheel speed. The signal is compared with a slip threshold value for antilock brake control. The slip threshold value is affected by the surface roughness signal outputted by the output 9 of the detector 6. In this way, the knowledge of surface roughness is used in the wheel antilock brake and traction control systems to vary the wheel slip and wheel spin threshold values.
