IPC: G01D5/246
Filed: 1981-01-16
Abstract: PURPOSE:To simplify the circuitry while facilitating the adjustment of the set control advance angle by obtaining a rotor position signal directly detecting the terminal voltage of a motor. CONSTITUTION:Terminal voltage of a motor 2 is detected with a transformer 9 and provided to a position detector circuit 10. In the circuit 10, output signals B of a zero-crossing detection circuit 12 is amplified by adjusting the variable resistance of an amplification circuit 13 to determine the time when a logic element of a logic circuit 16 reaches the threshold voltage Vs. The same operation is done for an amplification circuit 15. As a result, output signals G of the circuit 16 is obtained and a signal H is provided to a gate 3 through an FF17. In this process, with the adjustment of the variable resistance of the circuit 12, the inclination of the rising and the falling of the signal B is changed. The inclination of the rising and the falling of the amplified output signals C and D vary to change the time of reaching the voltage Vs thereby enabling the adjustment of the control advance angle beta0.

Abstract: PURPOSE:To decrease the time for a matching processing of a pattern and to make it possible to obtain the accurate amount of a positional deviation by a method wherein a correction processing for replacing with pixel data on one of the minimum level and the maximum level of the width, which is selected in the frame of a mask by a mask processing, of the mask is performed. CONSTITUTION:A correction processing for replacing with data on one of the minimum level and the maximum level of the width, which is selected by a mask processing, of a mask is performed. Accordingly, the contents of image data become the contents of data of a white, a half tone near a white, a half tone near a black or a black, the number of the gradations of the image data becomes lower than that of the gradations of image data picked first and moreover, the width of the edge parts of the mask becomes a thickness to correspond to the frame of the mask. As a result, the amount of data to be used as a whole is decreased, objects to be compared at the amount of data on a matching processing are reduced and the amount of a shift in the matching processing can be accurately calculated. Thereby, a high-speed and accurate matching processing becomes possible.

Title: Transmission system for event data
Inventor: AKASHI TETSUO
IPC: H04L29/08
Filed: 1991-01-23
Abstract: PURPOSE:To prevent the lack of event data while a system is switched by storing event data whose transmission is completed by means of a low-order station as a present state and transmitting event data in the present state which is stored when the system of a high-order station is switched as initial data. CONSTITUTION:When the regular system of the high-order station is sound, relevant data of a buffer 15 is updated and event data in the present state in a present state storage part 17 is updated to the relevant data when the transmission of event data in the buffer 15 is completed at the time of transmission. When a fault occurs in the regular system and a next even is generated in the low-order station while the high-order station is switched to a standby system, the data in the buffer 15 and the storage part 17 are held. When an initial request is received, an initial data editing part 19 fetches the data in the storage part 17, transfers it to a buffer 18 at the time of transmission and transmits it to the standby system. Thus, the standby system can be initialized and then data in the buffer 15 can be retransmitted, whereby the lack of data can be prevented.
