Title: Tab control system of serial printer
Inventor: KAMATA TAKAO
IPC: G06K15/08
Filed: 1979-12-27
Abstract: PURPOSE: To move a print head to a tab position in a high speed, by performing a flag retrieval of tab memory without stopping the movement of the print head after tab receiving.  
     CONSTITUTION: When receiving the tab code, microprocessor MPU1 takes in the address value of RAM3 and adds 1 to this value and sends the result to I/O port 4. Memory 5 is accessed according to this address value, and storage contents of the corresponding address are read out. Read contents are transferred to MPU1. MPU1 checks these contents; and if it is detected that the flag is set, the current position address value and the tab address are compared with each other to report the high-speed running instruction of output port 6. Then, driving circuit 7 rotates motor 8 in a high speed. MPU1 compares the current position address value and the tab address value with each other each time a character pulse is recevied; and when the difference between these address values becomes a prescribed value or less, the speed reduction instruction is issued. Then, motor 8 is decelerated, and the print head is moved from the tab position approximately in the normal print speed.

Title: Non volatile memory
Inventor: NAMIKI MASAYUKI
IPC: H01L29/788
Filed: 1980-12-04
Abstract: PURPOSE:To improve the effect of electron injection from an injector, and the integrity by making an SiO2 film sufficiently thicker than a control gate on a read transistor. CONSTITUTION:In the conventional method, SiO215 on a control gate and SiO216 on a read transistor are simultaneously formed films and the voltage transmitted to a floating gate 13 is lower than the voltage applied to the control gate and, consequently, a channel 14 is not sufficiently depleted which makes the electron injection by an injector less effective. The film 16, then, is formed as thick as other gate films in the order of 1,000Angstrom , which is sufficiently thicker than the film 15 to provide a large capacitance of the read transistor. No extra process is needed for this. In this construction, the voltage of the control gate is amply transmitted to the floating gate, improving the electron injection effect of the injector and the integration since the capacitance ratio is controlled by the thickness the SiO2 film and not by expanding the gate area.

Inventor: WADA YOSHIO
IPC: H04J13/00
Filed: 1993-06-17
Abstract: PURPOSE:To prevent deterioration in an S/N by restarting a synchronization acquisition section so as to ensure the correction even when detailed correction is failed after rough frequency correction. CONSTITUTION:A mixer 5 of a demodulator R mixes a frequency of a spread spectrum signal S and a local signal L from a modulator, and an inverse spread signal J from a multiplier 6 is fed to a phase comparator 15 and a synchronization acquisition section 9 provided with a DFT(discrete Fourier transformation) 8 and a data demodulation section 7. The demodulation section 7 extracts a signal component whose center frequency is f1 from a signal J at a BPF 10, a detector 11 detects an envelope to eliminate a carrier component and to demodulate data D, the acquisition system uses the DFT 8 to obtain the frequency spectrum of the signal J and a detection signal is fed to a PN series generator 4 via a timing circuit 12 till the level exceeds a predetermined value and a PN series MR is shifted by one bit to synchronize both PN series for modulation and demodulation. Thus, the deterioration in the S/N when the signal S is demodulated is completely prevented.

Filed: 1987-07-10
Abstract: PURPOSE:To reduce the increase of the area of layout, the delay due to wiring, and its variance by providing a group dividing means which divides the whole of gates in a logic circuit, a gate output destination classifying means, and a means of fan out adjustment based on classification result to perform adjustment of fan out. CONSTITUTION:Designation to divide gates in the circuit into groups is performed by a circuit group designating part 2. A table where output destinations of a clock input CIN11 are classified for respective groups is generated by a gate output designation classifying part 4. Finally, this table is referred to perform adjustment of fan out of the input CIN by a fan out adjustment executing part 5. Since the number of elements of a group G1 is five and the fan out limit number of a driver is five, the driver is inserted to the output destination of the input CIN and is connected to inputs of elements of the group G1. The driver is similarly connected with respect to a group G2. Since the number of elements of a group G3 is six, elements are divided by three and are connected to drivers for the purpose of equalizing loads. Consequently, the increase of the area after layout design, the increase of delay due to wiring, and the variance of delay are reduced.

Abstract: PURPOSE:To completely hold the influence of the phase noise of a local oscillator which is applied in a frequency conversion process and to increase jitter follow-up capacity by applying a pilot signal extracted from a demodulated signal to a phase comparator in a PLL without dividing the frequency of the pilot signal. CONSTITUTION:After demodulating a receiving signal by a demodulator 1, the demodulated signal is extracted as a signal through an amplifier 2. A pilot signal included in the extracted signal is extracted through a pilot extracting filter 3 and inputted to the phase comparator 51 with out dividing its frequency. The extracted pilot signal is influenced by the phase noise of the local oscillator in each conversion stage similarly to a transmission signal. On the other hand, the noise component of a pilot oscillator 7 is negligibly slight and a phase noise within a passing area of the PLL is superposed to a control voltage outputted from the phase comparator 51. When the loop band width is expanded, the phase noise is fed back to a demodulating carrier oscillator 6 and cancelled.
