Title: Method and circuit for demodulation processing of variable transmission rate signal
Inventor: YONEDA MASAYOSHI
IPC: H04L27/38
Filed: 1999-02-08
Abstract: PROBLEM TO BE SOLVED: To achieve flexible multi-media communication in accordance with an information amount or the state of a communication line and to realize a small-sized and light circuit and power consumption saving. SOLUTION: An A/D converter 4 digitally converts a signal Sb which is obtained by the quasi-synchronous detection of the data signal of an IF input signal whose transmission rate is varied by a quasi-synchronous detection circuit 1, based on a local signal. Then an automatic rate recognizing circuit 5 memories a digitally converted sampling signal Se, recognizes the respectively different data transmission rates from the signal Se and transmits a decision result Sm to a digital demodulating circuit 6. The circuit 6 varies a system clock based on the transmission rate of the received decision result Sm and respectively demodulates data of the digital signals having the different data transmission rates by the same algorithm.

Title: Sphere processing device
Inventor: MIYATANI TAKASHI
IPC: B24B37/02
Filed: 1985-02-20
Abstract: PURPOSE:To provide possibility of grinding even a single sphere by forming a space in a lapping table for accommodation of works to be ground, installing pins upright in this accommodation space isolatedly, and by allowing its space to accommodate the works to be followed by operation of the lapping table. CONSTITUTION:Works in ceramic 18 to be processed are put in a retaining space 19. Then a lapping table 11 is revolved in the direction of arrow in attached illustration, and at the same time is swung oscillatively in the direction of Arrow 15. Works 18 roll on a grinding layer 12 and run against pins 13 to make change in their respective rolling directions. That is, the works 18 make the rolling and sliding motions randomly with frequent reversals. Thus the outside surface of each work 18 is lapped evenly. This processing method ensures that even one isolated sphere is processed with high precision, to lead to provision of an enhanced flexibility for the processing operation, In addition, there is small variation in the lapping conditions, so that even processing of spheres in a great number can be performed with high precision, which should raise the rate of acceptance as well as the efficiency in processing operation.

IPC: H04L1/00
Filed: 1984-02-20
Abstract: PURPOSE:To decide a defect of a recording system by dividing an optical disk into plural sectors to detect errors of each sector and giving information to outside when the number of sectors containing errors exceeds a certain level. CONSTITUTION:The output Q of the 1st counter 3 is set at a high level every time each of sectors S1-S8 are reproduced. The 2nd counter 4 counts all sector synchronizing signals SCK, and the contents of the counter 4 are set at 8 by a revolution of an optical disk 1. The output Q of the counter 4 is already set at a high level when the contents of the counter 4 are set at 4. Then the output Q of a D flip-flop 9 is set at a high level by the output of a track synchronizing signal TCK. Thus a light emitting diode 11 glows. In this case, it is shown that >=1/2 sectors of a track have errors. As a result, a fault of a recording system is decided.

Abstract: PURPOSE:To remove a lateral stripe pattern on a screen in the gap area between scanning lines and to excellently correct the gap between scanning lines even when the number of scanning lines is decreased to 1/n times (n: interger) of a maximum value. CONSTITUTION:The number (n) of scanning lines is found from the horizontal and vertical synchronizing signals HS and VS of an input video signal and when the (n) is smaller than the maximum number N of scanning lines which can be displayed on a display device, namely, when there are gap areas generated between the scanning lines, an electron beam is polarized vertically with a high frequency signal together with a vertical saw-tooth wave signal and vibrated vertically on the screen to apparently increase the width of each scanning line on the screen. Therefore, the electron beam strikes on even the gap areas formed owing to a decrease in the number of scanning lines to solve the problem that an image becomes unclear owing to the lateral stripe pattern of the gap areas.

IPC: H03L7/085
Filed: 1991-02-27
Abstract: PURPOSE:To realize a frequency synthesizer in which a frequency range is large with a small frequency step and phase noise is less. CONSTITUTION:The output of a reference oscillator 1 is counted by a frequency divider 2 to output a modulo M count (m), then a step frequency is generated through 1/M frequency division. A phase conversion circuit 7 applies the arithmetic operation of K(m/M) to the counted value (m) to generate a reference phase signal. The output of a VCO 5 generating a signal at a required frequency being a multiple of a value N with the step frequency is counted by a programmable frequency divider 6, which outputs a modulo N counted value (n) to implement 1/N frequency division. A phase conversion circuit 9 applies the arithmetic operation of K(m/N) to the count value (n) to generate an output phase signal. An adder 7 generates a modulo K difference between the reference phase signal and the output phase signal. The output of an adder 8 is converted into an analog signal by a D/A converter 10, the signal is smoothed by a loop filter 4 and the result is used for a phase control signal of the VCO 5.
