Title: Frequency fluctuation detecting circuit and horizontal deflection output circuit
Inventor: SHIRATORI HIROSHI
IPC: G09G1/04
Filed: 1994-03-25
Abstract: PURPOSE:To provide a circuit being used in a multi-scanning type image display device provided with a CRT, being capable of detecting instantly the changeover of the frequency of an incoming horizontal or vertical synchronizing signal and being capable of attaining simultaneously the preventing of the high voltage abnormality of an equipment, etc., and the improving of the quality of a reproduced image. CONSTITUTION:When an F-V voltage is in an ascending stage, the voltage waveform of the inverting terminal of a comparator IC1 is made to be a waveform being delayed than the F-V voltage owing to the action of a first time constant circuit. When the F-V voltage is in a descending stage, the voltage waveform of the noninverting terminal of a comparator IC2 is made to be a waveform being delayed than the F-V voltage owing to the action of a second time constant circuit. Consequently, the output of the comparator IC1 becomes a high level at the instant when the horizontal frequency is changed over in the direction in which the horizontal frequency is increased and the output of the comparator IC2 becomes the high level at the instant when the horizontal frequency is changed over in the direction in which the frequency is decreased. Thus, the output voltage Vo of an NOR circuit becomes a low level for a time determined by the time constant only at the instant when the frequency of the horizontal synchronizing signal is changed over.

Title: Image forming device
Inventor: MISHIMA NOBUHIRO
IPC: H04N1/04
Filed: 1997-03-31
Abstract: PROBLEM TO BE SOLVED: To obtain an optimum image even from an original protruding from an original area by calculating the quantity of protrusion from the original area by extracting respective sides when that original placed on original glass protrudes from a read area, and inhibiting inclination correction when the result exceeds prescribed quantity. SOLUTION: In a reading with an original 10 placed inclined on a digital copy machine, an editing processing parameter can be found corresponding to every way of placing the original 10 and when one of four sides can be extracted at least, the calculation of inclination angle is enabled. When the original 10 is inclined, the read image can be automatically rotated at an arbitrary angle and corrected into normal image. When the protrusion from the read area is especially larger than a predetermined threshold value, however, since there is danger to generate image omission or the like, the correction of arbitrary angle rotation is inhibited and a caution message is displayed for a user.

Title: Engine controller
Inventor: TSURUMAKI KIYOSHI
IPC: G05B9/02
Filed: 1994-04-19
Abstract: PURPOSE:To avoid the situation that the control using the data becomes impossible by limiting an electrically deletion and write possible nonvolatile memory in the number of times of writing and generating the data destruction due to the excess of the number of times of writing. when the memory is used for the storage of data whose update is frequent. CONSTITUTION:An area storing the number of times of writing is saved at the inside of the EEPROM 9 within an engine controller 1. Before performing a writing in the EEPROM 9, the value is checked. When the value becomes the number of times of limitation, the writing of data is not performed. When the value is still smaller than the number of times of limitation, the writing of data and the number of times of writing are made incremental and they are stored in the EEPROM 9. Thus, the number of times of data rewriting in EEPROM 9 can be limited and the failure by the data destruction due to the excess of the number of times of writing in the EEPROM 9 can be evaded.

IPC: G01N27/414
Filed: 1983-05-09
Abstract: PURPOSE:To eliminate the effect affected to the potential in a measured solution by the potential of a substrate, source, drain and the like by a method wherein the surface of an FET sensor is covered with a semiconductor layer except a channel region and the semiconductor layer is biased at a suitable potential. CONSTITUTION:When an FET sensor is used as a PH sensor, the surface of its nitride film 15 is dipped in a solution 20 to be measured. An electrical double layer is produced between the surface of the nitride film. A current which flows between a source 12 and a drain 13 is modulated by a potential produced by the electrical double layer and this modulated current is measured to obtain the PH value of the measured solution 20. The surface of the FET sensor is covered with a semiconductor layer 31 except a gate layer and electrical contact metals 17. A potential is given to the semiconductor layer 31 by a terminal 32. As a substrate 11, the source 12 and the drain 13 are shielded by the semiconductor layer 31, their potential has almost no effect to the potential in the measured solution. It is preferrable to make the potential of the semiconductor layer 31 and the potential of a comparing electrode 26 nearly equal with each other.
