Title: Malfunction detecting system for serial printer
Inventor: NARITA MASAHISA
IPC: B41J7/96
Filed: 1979-07-31
Abstract: PURPOSE: To detect immediately the printing malfunction, by collating the count pulse which is generated in accordance with the rotation of the print head with the print check signal generated synchronously with the count pulse.  
     CONSTITUTION: Signal converting circuit 26 generates "1" or "0" in accordance with the output signal of present-position counter 12 at the moment the count pulse is generated, and then inverts "1" and "0" with every two units of the count pulse. At the same time, the initial state is set to the phase of the print check signal which is obtained when the selection of print head 3-1 is carried out properly. Accordingly, the coincidence must always be obtained through the collation given by coincidence detecting circuit 27 between the print check signal of register 25 and the output of signal converting circuit 26 and in case the count pulses are generated normally and counted. In this connection, the output is obtained through circuit 27 in case no coincidence is obtained through the collation given every 1/2 pitch of the rotation of the print head. Thus the fault is informed to the external control unit, and then the hammer action of e.g. print head 3-1 is discontinued to prevent the printing of wrong characters.

Title: Method for measuring ac characteristic of microprocessor
Inventor: ENAMI TOMOKAZU
IPC: G06F11/24
Filed: 1992-04-20
Abstract: PURPOSE:To reduce measuring errors in the measurement of an AC characteristic by removing a connection line, impressing an AC tester testing pulse to a connection terminal and measuring the AC characteristic of a CPU. CONSTITUTION:A processing output signal from the CPU 12 is outputted from a connection terminal 104 to an external circuit 14 through a driver 152 synchronously with a clock signal inputted from a connection terminal 103. In this case, a driver having a minimum power amplification factor required is sufficiently used as a driver 151. Measurement for the evaluation of an AC characteristic (a time characteristic between change points of an I/O signal) is executed by inputting an IC testser clock signal to the terminal 103. When it is necessary to evaluate only a clock oscillator part included in a clock generator 11, a crystal oscillator 111 is removed and the AC testser clock signal is inputted to a connection terminal 101. Thereby measurement for the evaluation of the AC characteristic can easily be executed.

IPC: H02M7/757
Filed: 1982-06-11
Abstract: PURPOSE:To control a load current at a high speed and with high precision, by employing an actual circulating current as a circulating current command added to a load current command. CONSTITUTION:The load current command 104(A) is inverted by a signal inversion part 31 into a pattern (B) and the circulating current command 106(C) is applied to the 1st and the 2nd thyristor converters, respectively. Then when they flow a current (D) to a load and further flow the circulating current (E), detected currents 100 and 102 are obtained from a current detector. Those detected currents 100 and 102 are applied to an adder 32 by switching the current (E) by a switching part 40 at times T1-T2. This current (E) flows on the basis of the circulating current command 106(C) and includes the delay of the system, etc., so the current command is added to the load current command 104(A) to obtain a command signal (D) of a forward side. Consequently, current control conforming to the load current command 104 and circulating current command 106 is performed at the high speed and with the high precision.

Filed: 1991-04-04
Abstract: PURPOSE:To calculate the machining time without producing the numerical control information nor performing any machining simulation when the machining order is changed in such a case where the single machining operations are changed to plural simaltaneous machining operations. CONSTITUTION:A machining time calculation data generating part 10 generates the machining time calculation data SF based on the machining process data SC stored in a machining process data storage part 3 and the machining order data SD stored in a machining order data storage part 6 and stores the data SF in a machining time calculation data store part 11. The data SF is used in each machining process for calculation of the cutting feed time at a fixed peripheral speed process, the fast forward time, and the cutting feed shift distance. Thus the numerical control information is temporarily produced with all machining processes defined for the fixed peripheral speed processes. Then the data SF is calculated by the internal machining simulation. A machining time calculation part 12 calculates the machining time data SE based on the data SF.
