Title: Automatic frequency characteristic measuring apparatus
Inventor: NAKASHIMA HIROYUKI
IPC: G01R27/28
Filed: 1979-03-28
Abstract: PURPOSE: To accomplish a higher measuring accuracy and efficient measuring work in the measurement of frequency characteristics by forming a variable frequency signal enabling direct reading of the frequency as a digital signal utilizing the PLL technique.  
     CONSTITUTION: The output fO of the voltage controlling oscillation circuit 5 in the PLL circuit is fed to the material 12 to be measured as the frequency signal and the outut signal is fed to a comparator 9. The comparator forms a coincidence signal between the signal inputted and reference signal Vref corresponding to the output signal to be detected. The coincidence signal is inputted to a one-shot generating circuit 10 to form a timing signal. Resetting the FF circuit 8, the timing signal controls the AND gate G 1  to prohibit the feed of the output pulse from the program counter 6 as clock signal of the counter 7 thereby halting the counter action, while the timing pulse controls the memory circuit 13. In this manner, the output of the counter 7 at this point is written. The information memorized in the memory circuit 13 is converted into the frequency signal to measure the characteristics thereof.

Title: Load pulse generating circuit
Inventor: ITO ETSUKO
IPC: H04L27/34
Filed: 1987-02-19
Abstract: PURPOSE:To attain accurate coding/decoding by using a retiming control pulse from a load pulse retiming control means so as to clear a load pulse generating means. CONSTITUTION:A 1st clock generating means 30 uses a coding rate set value and an error correction coding/decoding clock so as to generate the 1st clock having the same period as the data period and the retiming pulse to adjust the operation of the load pulse generating means 31 so that the change point of a load pulse comes in the nearly midpoint of adjacent change points of the 1st clock. Moreover, when a load pulse retiming control means 32 detects that the change point of the generated load pulse is at the outside of a prescribed range in a period of a timer pulse, the load pulse generating means 31 is reset by using the retiming control pulse sent therefrom to bring forcibly the change point of the load pulse to the midpoint region. Thus, the load pulse is generated at nearly accurate period.

Title: Welding process stopping method and welding device
Inventor: HOLVERSON TODD
IPC: B23K9/095
Filed: 1999-02-16
Abstract: PROBLEM TO BE SOLVED: To prevent a formation of a large ball by controlling a current corresponding to the short circuit formation, at the first level sufficient to clear a short circuit, then at a low level when the short circuit is cleared, and by repeating these steps until the short circuit formation does not take place. SOLUTION: A micro processor 808 stops a motor, upon receipt of a stop signal, by using a publicly known wire feed motor speed instruction signal, outputs a low constant voltage instruction, and maintains an arc for a period that the feed speed is reduced until it reaches a given feed speed. A control means 807 monitors an arc voltage and instructs a current buildup when the short circuit is detected. When the arc voltage reaches a threshold limit value, which is based on welding data, and shows a generation of the short circuit, the current buildup instruction is ceased and an extremely low current is instructed. When the short circuit is generated because the wire is kept to be fed and contacts with a paddle or the paddle is backflown and touches with the wire, routine is repeated and the large ball is not formed at the end of the wire.

Abstract: PURPOSE:To improve the operability and to decrease the retrieval time by converting an input character into a predetermined voiceless character when the input character has a specific sound such as a voiced sound or a p-sound so as to retrieve a Kanji(Chinese character) corresponding to the sound. CONSTITUTION:Let a character string to be converted be 'Gaisha'. In depressing the next candidate key, 'Gaisha (foreign car)' is stored in a synonym buffer SB, and since the voiced sound 'Ga' is regarded as a voiceless sound 'Ka' and the dictionary is accessed by the reading 'Kaisha', the corresponding Kanji 'Kaisha (company)' is stored in the buffer SB. In depressing the next candidate key, the 'Gaisha (foreign car)' is displayed as the 1st candidate. In depressing the next candidate key again, the 2nd candidate 'Kaisha (company)' is displayed. When the operator depresses the conversion key, the reading of the 'Gaisha (foreign car)' is converted into the Kanji 'Kaisha (company)' through Kana-Kanji conversion and as the display,the 'Kaisha (company)' is fixed.
