Title: Scanning type probe microscope
Inventor: IZUNO GUNPEI
IPC: G01B21/30
Filed: 1994-11-18
Abstract: PURPOSE: To collect data with a high time resolving power by allowing a second transmission means to start transmission processing during the transmission of the analogue data of detected surface data by a first transmission means. CONSTITUTION: A drive circuit 2 generates analogue saw-tooth waves to drive a piezoelectric element 3 to send a data taking-in trigger signal to a CPU 1. A cantilever 4 detects the data on a sample to send an analogue signal 10 to an A/D converter row 6. The CPU 1 receiving the trigger signal outputs a changeover start signal 12 to a multiplexer 5. The multiplexer 5 changes over the A/D converters 6a-6n of the converter 6 successively on the basis of an A/D conversion start signal 13 to output a trigger signal to issue a command for the respective converters to latch analogue data and to start conversion. At this time, the converter 6a starts conversion and a command is issued for the converter 6b to perform latching of the analogue data and the start of conversion during the execution of conversion.  When the conversion of the converter 6a has been completed, an FIFO buffer 7 inputs an A/D conversion completion signal 14 and a digital signal 11 to display an image on a host computer 9.

IPC: F02P5/10
Filed: 1985-12-20
Abstract: PURPOSE:To prevent the unstable control of ignition timing and improve the drivability, by stopping a feedback control of ignition timing when a maximum timing of a cylinder pressure is within a predetermined range. CONSTITUTION:In a control unit 100, a cylinder pressure as an output from an amplifier 4 is A/D converted by an A/D converter 104, which is repeated until a predetermined angle, and each value is stored.

Title: Synchronizing circuit for time base correction circuit
Inventor: UGAKI HIDEHIRO
IPC: H04N9/89
Filed: 1989-10-31
Abstract: PURPOSE:To quicken a pull-in speed and to attain smooth reproduction even at special reproduction by discriminating the presence of the lock state based on a horizontal synchronizing signal and a 1st clock signal and increasing the weight of a signal from a 2nd phase comparator circuit in non-lock state. CONSTITUTION:A horizontal synchronization discrimination circuit 26 discriminates whether or not a signal from a voltage controlled oscillator (VCO) 18 is synchronously with a horizontal synchronizing signal included in a video signal. When the circuit 26 discriminates the non-lock state, a phase difference signal HPD from a phase comparator 24 is added to a phase difference signal from a phase comparator 16 through the parallel connection between resistors R1, R3 and a resistor R2. Thus, the effect of the phase difference signal HPD from the phase comparator 24 onto the VCO 18 is increased in the nonlick state more than that in the lock state. Thus, the pull-in speed of the VCO 18 is quickened more than the case of only the resistor R1.

Title: Image-reading device and its control method
Inventor: YOSHIDA HIROYOSHI
IPC: H04N1/04
Filed: 1996-10-09
Abstract: PROBLEM TO BE SOLVED: To avoid a case in which the originals are fed and read with no storage of the original data and without assurance by stopping the feed of the next original, if each page memory has no spare capacity equivalent to one page of original. SOLUTION: It is decided whether the next original has reached a critical point. If the next original already reached the critical point, it is decided whether the status is normal. If the status is not set in a normal operation mode, it is decided whether the page memories 119 and 120 have the spare capacity of image data equivalent to one page of original. If both memories 119 and 120 have no spare capacity equivalent to one page, the feed of the next original is stopped, and the spare capacity of the memories 119 and 120 are decided again. Thus, it is possible to avoid such a case in which the next step is carried out even if it is not assured that the image data can be stored in both memories 119 and 120.

Title: Image data coder
Inventor: AKAOGI KAZUNARI
IPC: H04N19/136
Filed: 1993-11-16
Abstract: PURPOSE:To reduce data quantity of generated codes and to decrease the storage capacity of a coding table as required. CONSTITUTION:A difference of DCT coefficients in the unit of a block is coded. When a comparator 12 decides the difference of the DCT coefficients to be smaller than a minimum coefficient, a selector 16 is used to replace the difference of the DCT coefficients with the minimum coefficient. When a comparator 14 decides the difference of the DCT coefficients to be larger than a maximum coefficient, the difference of the DCT coefficients are replaced with the maximum coefficient. Since a range of DCT coefficients to be coded is made narrow, the information quantity allocated to codes is reduced and generated data quantity is decreased.
